[PMID: 38713986 DOI: 10.1016/j.psj.2024.103777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 04/15/2024] [Accepted: 04/17/2024] [Indexed: 05/09/2024] Open
Abstract
This study aimed to determine the influence of black soldier fly larvae oil calcium salt (BSFLO-SCa) supplementation on performance, jejunal histomorphology and gene expression of tight junctions and inflammatory cytokines in laying hens. A total of 60 ISA Brown laying hens (40 wk of age) were divided into 3 treatment groups, including a control group fed a basal diet (T0) and basal diets supplemented with 1% (T1) and 2% (T2) of BSFLO-SCa. Each treatment group consisted of 5 replicates with 4 laying hens each. Results showed that 1% and 2% BSFLO-SCa supplementation significantly reduced (P < 0.05) feed conversion ratio (FCR), while egg weight (EW) increased (P < 0.05). The inclusion with 2% increased (P < 0.05) both egg production (HDA) and mass (EM). The addition of 1% and 2% BSFLO-SCa significantly increased (P < 0.05) villus height (VH) and villus width (VW), while crypt depth (CD) significantly increased (P < 0.05) with 2% BSFLO-SCa. The tight junction and gene expression of claudin-1 (CLDN-1), junctional adhesion molecules-2 (JAM-2), and occludin (OCLN) were significantly upregulated (P < 0.05) with 2% BSFLO-SCa. The pro-inflammatory cytokines and gene expression of interleukin-6 (IL-6) was significantly downregulated (P < 0.05) with the addition of BSFLO-SCa, while gene expression of interleukin-18 (IL-18), toll-like receptor 4 (TLR-4), and tumor necrosis factor-α (TNF-α) were downregulated with 2% BSFLO-SCa. On the other hand, the anti-inflammatory cytokines and gene expression of interleukin-13 (IL-13) and interleukin-10 (IL-10) were significantly upregulated (P < 0.05) at 2% BSFLO-SCa. In conclusion, dietary supplementation with 2% BSFLO-SCa improved productivity, intestinal morphology and integrity by upregulating tight junction-related protein of gene expression of laying hens. In addition, supplementation with BSFLO-SCa enhanced intestinal immune responses by upregulating anti-inflammatory and downregulating pro-inflammatory cytokine gene expression.

Black soldier fly larvae meal supplementation in a low protein diet reduced performance, but improved nitrogen efficiency and intestinal morphology of duck. Anim Biosci 2024; 37:678-688. [PMID: 37946415 PMCID: PMC10915214 DOI: 10.5713/ab.23.0259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 09/05/2023] [Accepted: 10/23/2023] [Indexed: 11/12/2023] Open
Abstract
OBJECTIVE Reduced crude protein (CP) diets offer potential benefits such as optimized feed efficiency, reduced expenses, and lower environmental impact. The objective of this study was to evaluate black soldier fly larvae (BSFL) meal on a low-protein diet for duck performance, blood biochemical, intestinal morphology, gastrointestinal development, and litter. METHODS The experiment was conducted for 42 days. A total of 210-day-old male hybrid ducklings (5 replicate pens, 7 ducks per pen) were randomly assigned to 6 dietary treatments (3×2 factorial arrangements) in randomized design. The factors were CP level (18%, 16%, 14%) and protein source feed soybean meals (SBM), black soldier fly larvae meals (BSFLM). RESULTS Reduced dietary CP levels significantly decreased growth performance, feed intake, the percentage of nitrogen, pH (p<0.05), and tended to suppress ammonia in litter (p = 0.088); increased lipid concentration; and enhanced relative weight of gastrointestinal tracts (p<0.05). In addition, dietary BSFL as a source of protein feed significantly increased lipid concentration and impacted lowering villus height and crypt depth on jejunum (p<0.05). CONCLUSION In conclusion, the use of BSFLM in a low-protein diet was found to have a detrimental effect on growth performance. However, the reduction of 2% CP levels in SBM did not have a significant impact on growth performance but decreased nitrogen and ammonia concentrations.

Effect of nutmeg essential oil (Myristica fragrans Houtt.) on methane production, rumen fermentation, and nutrient digestibility in vitro. Sci Rep 2024; 14:3554. [PMID: 38347010 PMCID: PMC10861442 DOI: 10.1038/s41598-024-52532-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 01/19/2024] [Indexed: 02/15/2024] Open
Abstract
The study evaluated the effect of adding of nutmeg (Myristica fragrans Houtt.) essential oil (NEO) as a feed additive on methane production, rumen fermentation parameters, rumen enzyme activity, and nutrient digestibility in vitro. This study was divided into three treatments based on the level of NEO addition, which included 0 µL/L (T0), 100 µL/L (T1), and 200 µL/L (T2). The feed substrate composition consisted of king grass as forage and concentrate in a 60:40 ratio. Feed fermentation was conducted using the Menke and Steingass gas production and two-step Tilley and Terry in-vitro digestibility technique. The data obtained from the study were analyzed using one-way ANOVA and if there were differences between means, they were further assessed using DMRT. The results showed that T2 treatment significantly decreased (P < 0.05) ammonia (NH3) levels, total VFA, acetate, propionate, butyrate, and microbial protein (P < 0.05). Methane production and the activity of rumen protease enzyme significantly decreased (P < 0.05) at T1 and T2 treatment. The T2 treatment significantly reduced (P < 0.05) protein digestibility (IVCPD) at 48 h, while IVCPD at 96 h significantly increased (P < 0.05). On the other hand, the addition of nutmeg essential oil did not effect the activity of the amylase, carboxymethyl cellulase, and β-glucosidase enzymes, as well as the in-vitro digestibility of dry matter (IVDMD), crude fiber (IVCFD), and organic matter (IVOMD). The conclusion drawn from this study is that the optimum level for NEO is 200 µL/L, which can reduce methane production and increase crude protein digestibility at 96 h without any negative effect on rumen fermentation and nutrient digestibility.

Utilization of marigold leaves ( Tagetes erecta L.) in rations and their effect on rumen enzyme activity, fermentation parameters, methane emission, and nutrient digestibility in vitro. J Adv Vet Anim Res 2023; 10:782-793. [PMID: 38370886 PMCID: PMC10868681 DOI: 10.5455/javar.2023.j734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 10/25/2023] [Accepted: 10/26/2023] [Indexed: 02/20/2024] Open
Abstract
Objective This study evaluated the utilization of marigold leaves (MGLs) in rations and their impact on rumen enzyme activity, fermentation parameters, methane (CH4) emission, and nutrient digestibility in vitro. Materials and Methods The experimental diets comprised different proportions of MGL incorporated into the dry matter (DM) rations. Experimental design: The MGL treatments in diets include 0% (MGL-0), 7% (MGL-7), and 14% (MGL-14). Results Results indicated that MGL-14 substantially raised (p < 0.05) the rumen parameters, including NH3-N and microbial protein, total volatile fatty acids, acetate (C2), propionate (C3), butyrate (C4), and the C2:C3 ratio. In contrast, the MGL-7 and MGL-14 groups experienced a noteworthy reduction (p < 0.05) in the total protozoa population. The MGL-7 and MGL-14 treatments also led to a substantial increase in the digestibility of DM, organic matter (OM), and crude fiber (CF) in the rumen. However, they also resulted in a decline (p < 0.05) in crude protein (CP) digestibility. The DM and OM total digestibilities were higher (p < 0.05) in the MGL-14 and MGL-7 groups. The utilization of MGL did not influence (p > 0.05) the ruminal enzyme activities (carboxymethyl cellulase, amylase, protease), cumulative gas production, kinetics, ruminal pH value, CH4 and CO2 production, total CF, and CP digestibility. Conclusion The utilization of MGL until 14% DM in diets can enhance ruminal fermentation parameters and nutrient digestibility in vitro without negatively affecting gas production kinetics or ruminal enzyme activities. However, it did not have any impact on CH4 production.

Abstract
This study evaluated the effect supplementation of black soldier fly larvae oil calcium salt (BSFLO-SCa) on performance, blood biochemical profile, carcass characteristic, meat quality, and gene expression in fat metabolism broiler chickens. A total of 280 male New Lohmann strain MB 202 broiler chicks (1-day-old) were randomly placed into 4 treatments, including a control group (T0) were fed basal diet and a basal diet supplemented with 1% (T1), 2% (T2), and 3% (T3) BSFLO-SCa. Each treatment consisted of 7 pens with 10 chickens each. Results showed that 1% BSFLO-SCa supplementation significantly reduced (P < 0.05) abdominal and meat fat, while gene expression on fat synthesis (FAS, ACC) was downregulated. Meat fatty acid profiles such as medium-chain fatty acid being dominant in lauric and myristic and monosaturated fatty acid significantly increased (P < 0.05). On the other hand, polyunsaturated fatty acid significantly decreased (P < 0.05). In addition, the other parameters did not affect by supplementation of 1% BSFLO-SCa. The addition starting from 2% significantly reduced (P < 0.05) performance and carcass characteristics. Blood biochemical profiles (HDL, protein, albumin) and meat qualities (protein, cholesterol, water-holding capacity, cooking losses, a* (redness), and b* (yellowness) values) were significantly increased (P < 0.05), while gene expression on fat oxidation (CPT-1) was upregulated. In conclusion, broiler chicken that received of 1% BSFL-SCa does not negatively affect growth performance and carcass characteristics but reduced fattening in broiler meat.

Abstract
This study was conducted to evaluate growth performance, carcass yield, intestinal morphology, organ development, nutrient digestibility, and blood biochemical parameters of broiler fed 1% reduced-protein diets with/without protease supplementation. A total of 1,120 one-day-old male broiler chickens with average initial body weight (BW), 46.45 ± 0.49 g, were divided into five groups with seven replications and 32 birds per replication. The treatment varied according to the protein and protease enzyme levels: positive control (PC), negative control (NC, PC with reduction of 1% protein), PC supplemented with 50 g/t protease (PC + 50), NC supplemented with 50 g/t protease (NC + 50), and NC supplemented with 100 g/t protease (NC + 100). The results showed that there was no significant effect of 1% reduced-protein diets, with or without protease on feed intake, final BW, average daily gain, feed conversion ratio, and nutrient digestibility. The changes in dietary protein level and supplementation of protease did not affect carcass yield, but significantly affected abdominal fat content, PC + 50 group had significantly lower abdominal fat content than NC-based diet including NC, NC + 50, NC + 100. Reduced-protein with protease supplementation strongly affected organ weight, especially on day 21: the pancreas was heavier in PC and NC + 50 group than other groups, spleen was heaver in NC group than in NC + 100 group, thymus was heavier in NC + 50 group than in PC, NC and NC + 100 group, small intestine was heavier in NC + 50 and NC + 100 group than in PC group, and large intestine was also heavier in NC + 50 group than in NC group. Villus height sampled at 35-d was significantly increased with protease supplement, and which was significantly higher in NC + 100 group than NC group. Regarding on blood metabolites, only urea and uric acid were affected by the reduction of dietary protein, broiler fed PC diet had higher urea and uric acid content than fed NC diet. In conclusion, supplementation of 50 g/t protease in 1% reduced-protein diets does not negatively affect on growth, nutrient digestibility, carcass yield, organ development, and blood metabolites. Moreover, supplementation of protease in low-protein diet could effectively promote organ development and benefit intestine morphology.

Abstract
Soybean oil is a high source of unsaturated fatty acids which if given to sheep have the potential to accumulate in the meat. However, in the rumen unsaturated fatty acids undergoes biohydrogenation by rumen microbes, and the addition of fat in the feed has the potential to reduce fiber fermentation in the rumen which can have an impact on animal performance. This study aimed to determine the effect of the combination of protected and non-protected soybean oil supplementation on the characteristics of rumen fermentation, nutrient digestibility, and nitrogen balance of Garut sheep. Twelve male Garut lambs aged 13 months and weighing 29±3.23 kg were kept in a metabolic cage and divided into three groups. The basal diet of 60% King grass and 40% pollard bran was supplemented with protected and non-protected soybean oil with the ratio of 3%:0%, 1.5%:1.5%, and 0%:3%, respectively, based on the dry matter of ration. The data obtained were analyzed by One-Way ANOVA, followed by the Duncan Multiple Range Test (DMRT). The results showed that supplementation had no effect on rumen fatty acids profile, microbial protein, ammonia concentration, total volatile fatty acids, acetat, propionate, butirat, and pH. The digestibilities of dry matter, organic matter, crude protein, crude fibre, and crude fat were not affected. Supplementation also had no effect on nitrogen balance. Hence supplementation of different levels of protected fats did not influence animal performance in Garut sheep.

Abstract
The glass house experiment involving compost tea and harvest age was conducted to investigate the effect of giving compost tea (cricket and rabbit feces) and harvesting age on productivity, nutrient content, and in vitro digestibility value of Cichorium intybus. Compost tea (CT) is an aqueous extract from compost that can correct nutrient deficiencies during crop production and protect cultivation. The research treatment consisted of two factors, namely: the age of harvest and the dose of compost tea. The administration of compost tea consisted of three kinds of doses as follows: no compost tea (P0), 200 mL of compost tea (P1), and 400 mL of compost tea (P2). The experimental plants were harvested at different age, consisting of 25, 35 and 45 days after planting (DAP). The experimental design was Factorial Completely Randomized Design (CRD) with 6 treatments and 9 replications. The data were statictically analyzed using analisys of variance, and differences among value of each treatment were tested with the Duncan Multiple Range Test. The results indicated that compost tea dose and harvesting period treatment affected (P<0.05) leaf length, fresh leaf weight, crude protein content, dry matter digestibility (DMD), and organic matter digestibility (OMD). Meanwhile, it showed not significant effect (P>0.05) on the leaf width and root length. The results suggest that the fertilization treatment of 200 mL of compost tea and 25 DAP could increase productivity (leaf length and fresh leaf weight) of chicory, nutrient content (crude protein) of chicory, and in vitro digestibility (DMD and OMD).

Abstract
This study investigated the effect of feeding atung (Parinarium glaberrimum Hassk.) seed meal on growth performance and haematology profile in broiler chickens. A total of 140 one-day-old male New Lohmann broiler chicks were randomly assigned to five treatment groups with four replicates and seven birds in each replicate pen. The dietary treatments consisted of feeding the same corn-soybean meal as the basal diet with atung seed powder inclusions at levels of 0, 0.5, 1.0, 2.0, and 4.0%, respectively. The data were statistically analyzed using One-way with five treatments and four replications and continued with Duncan's New Multiple Range Test for data with a significant difference. Results showed that feed intake increased (p<0.05) in broiler chickens fed diets with 0.5 and 1% atung seed powder. At the same time, the inclusion of atung seed powder had no effect on final body weight, weight gain, and FCR. Inclusion of 1 and 2% atung seed powder significantly increased leucocyte counts, as well as the PCV value trend increased with the inclusion of atung seed powder. It can be concluded that atung seed powder additives can be supplemented in broiler chickens feed at doses 1% by improving feed intake and some haematological profiles.

Abstract
This research was carried out to examine the chicory forage yields on different regrowth which were intercropped with Pennisetum purpureum cv. Mott (dwarf elephant grass) on different regrowth due to various harvest age. The research was conducted in the Laboratory of Forage and Pasture, Faculty of Animal Science UGM for 7 months, with a split-plot design and analyzed by Duncan with a total of 9 plots and an area of 2.5x2.5 m2 for each plot. The main plot was the harvest age treatment (30, 45, and 60 days) and the subplot was the regrowth (first and second). In the first stage, as many as 9 cuttings of dwarf elephant grass in one plot were planted with a spacing of 1x1 m2 until the plant height reaches 10 to 15 cm, then the chicory seeds were spread among the dwarf elephant grass plants with the sand mixture. The results showed the harvest age had a significant effect (P<0.05) on chicory's plant height, fresh forage yield, dry matter content, dry matter digestibility, and organic matter digestibility. The 30 to 45 days harvest age performed a higher fresh production more than the 45 days to 60 days harvest age. The 60 days harvest age and second regrowth yielded the highest mixed fresh production compared to the other harvest ages, namely from 12.50 ton/ha to 25.26 ton/ha. Based on the research results showed that the older the harvest age (60 days) increased the biomass of plant production but decreased the plant digestibility. The second regrowth was able to produce higher than the first regrowth, but there was no significant effect on the dry matter content and forage digestibility.

Variables measured were the digestibility of dry matter, organic matter, and crude protein in the rumen as well as the total digestive tract digestibility based on in vitro technique. The data obtained were analyzed by One Way ANOVA, and followed by the Duncan Multiple Range Test (DMRT). The results showed that rumen dry matter digestibility was lower (P<0.05) in P1 and P2 (59.03±3.24 and 57.19±1.32) compared to P0 (70.77±1.05), but did not show a significant difference (P>0.05) in the total dry matter digestibility of P0, P1, and P2 (74.88±5.28, 67.70±3.21, and 64.83±4.96). Organic matter digestibility in the rumen was also lower (P<0.05) in P1 and P2 (55.55±6.29 and 55.76±6.88) compared to P0 (75.39±0.91), but did not show significant difference (P>0.05) in total organic matter digestibility from P0, P1, and P2 (64.69±6.44, 64.33±6.34, and 61.20±5.11). The digestibility of crude protein in the rumen at P1 and P2 (45.48±5.12 and 38.47±3.44) was also significantly lower (P<0.05) compared to P0 (60.93±9.72), whereas total digestibility did not show any significant difference (P>0.05). Addition of tannin leaf nutmeg 2% optimally reduced rumen dry matter and crude protein digestibility without causing excessive negative impact on results of in vitro digestibility, so it can be used as a protective agent protein feed.

Abstract
This experiment aimed to determine the nutrient digestibility of Bligon and Kejobong goats fed by king grass and peanut straw. The sample used was 6 to 8 months of five male Bligon goats, and five male Kejobong goats with the initial body weight of 15 to 20 kg and placed in separated metabolism cages. The diet and water were supplied ad libitum. This experiment was done in 14 days of adaptation period and seven days of the collection period. In the collection period, samples of feed, refusal feed, and feces were collected to get the chemical content includes dry matter (DM), organic matter (OM), ether extract (EE), crude fiber (CF), crude protein (CP), nitrogen-free extract (NFE), and total digestible nutrient (TDN). The data obtained were subjected to a T-test analysis. Results showed that nutrients intake, digested nutrient as well as nutrient digestibility of Bligon and Kejobong goats were not significantly different. However, Kejobong goats had EE and CP intake of 15.42% and 14.02%, digested DM, OM, and NFE of 16.29%, 15.71%, and 13.93% respectively, as well as NFE digestibility 4.37% higher than those Bligon goats (P< 0.05). Therefore, there was no difference in nutrient intake, digested, and digestibility of nutrients in Bligon and Kejobong goats fed by king grass and peanut straw. However, Kejobong goats appeared to have higher EE and CP intake, as well as digested and digestibility of DM, OM, and NFE than Bligon goats.

Abstract
The objective of this study was to determine the activity and the stability of bacteriocin from lactic acid bacteria (BAL) isolated from rumen fluid of thin-tail sheep under the temperature (80, 100, and 121°C), pH (3, 7, and 10), and the length of storage (for 2 weeks under the temperature -8, 11, and 29°C). Lactic acid bacteria obtained by isolation, selection, and identification of thin-tailed sheep rumen fluid were used for bacteriocin production. The crude bacteriocin was partially purified using 70% ammonium sulfate, then was dialysis for 12 hours. The obtained bacteriocin then tested its inhibitory activity against E.coli (representing Gram-negative) and S. aureus (representing Gram-positive) under temperature (80, 100, and 121°C), pH (3, 7, and 10), and the length of storage (for 2 weeks under the temperature -8, 11, and 29°C). The data of bacteriocin activity based on pH, temperature, and the length of storage were analyzed with factorial, then when there was a significant difference of variable because treatment was continued with Duncan's Multiple Range Test (DMRT) test. The results showed that the bacteriocin activity of the three types of BAL against S.aureus is greater than E.coli. The highest activity was shown in pH 3, while the lowest activity was shown at pH 10 (P<0.01). The highest activity was shown at a heating temperature of 100°C, while the lowest activity was shown at a heating temperature of 80°C (P<0.01). The activity of bacteriocin produced by BAL 0 A, BAL 1 A, and BAL 4 C tended to be stable to the heating temperature of 80, 100, and 121°C but decreased with increasing pH value (pH 3, 7, and 10). The best of bacteriocin activity was found at pH 3 (acid), heating at 100°C, and stored at -8°C for 14 days.

Abstract
This study was aimed to determine the effects of protease supplementation in diets with agricultural-livestock by products on the growth performance in broiler chickens. The commercial protease used in current study was produced by Bacillus licheniformis which based on keratinase. The treatment diets were a control basal diet without agricultural-livestock by-products and protease supplementation (P1); P1 + 0.05% protease; basal diet with meat bone meal (MBM) and distiller’s dried grain with soluble (DDGS) suppementation (P3); P3 + 0.05% protease (P4); basal diet with hydrolized chicken feather meal (HCFM) and DDGS supplementation (P5); P5 + 0.05% protease. The obtained data were statistically analyzed using Complete Randomized Design, and analyzed subsequently by Orthogonal Contrats Test. Results showed that protease supplementation in the diets containing agricultural-livestock by-products did not affect growth performance of broiler chickens in starter phase and overall age phase. However, in diets containing MBM, protease supplementation reduced the nett gain and feed conversion ratio (FCR) in finisher phase (P<0.05). In diets containing HCFM, protease supplementation increased nett gain and FCR (P<0.05), compared to those of containing MBM. It could be concluded that qualified HCFM, MBM, and DDGS can be used as alternatives for protein-energy source feed stuffs in starter phase, as they did not reduce growth performance of broiler chickens. Protease used in this study might be more effective in diets containing HCFM than those of containing MBM and DDGS.Keywords: Agricultural-livestock by-products, Broilers chickens, Growth performance, Protease.

Abstract
BACKGROUND AND OBJECTIVE Bacillus subtilis is a bacterium that can produce the oxalate decarboxylase (ODC) enzyme. This enzyme decomposes oxalate. ODC enzyme activity is influenced by temperature and pH. This study was conducted to determine the optimum pH and temperature for ODC enzyme activity in B. subtilis FNCC 0059. MATERIALS AND METHODS B. subtilis was cultivated in oxalate medium at different incubation temperatures for 24 h. The tested temperatures were 25, 29, 33, 37, 41 and 45°C. In separate experiments, cultures were grown in oxalate medium at varying pH from 4-8.5. The cell growth assay and enzyme activity were performed and all the experiments were done with 3 replicates. Data were analyzed using one-way analysis of variance. RESULTS The optimum temperature of 37°C could produce maximum ODC enzyme activity (0.041 U mL-1) enzyme activity increased to the point of the optimum pH and then decreased 5.6% when the pH was increased 0.5 from the optimum. Maximum ODC enzyme activity (0.0413 U mL-1) was achieved at pH 5.5. CONCLUSION Temperature and the pH of the medium affected ODC enzyme activity. Optimum medium condition of B. subtilis was reached at 37°C and pH 5.5.
