Cottonseed meal with enzyme complex for finishing pigs. Trop Anim Health Prod 2021; 53:306. [PMID: 33956237 DOI: 10.1007/s11250-021-02762-8] [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: 08/19/2020] [Accepted: 05/02/2021] [Indexed: 10/21/2022]
Abstract
This work evaluated the digestibility of the experimental diets, the performance and the economic viability of pigs in the finishing phase fed with diets containing increasing levels of cottonseed meal (CM) with enzymatic complex. In the digestibility test, 35 barrows with an average weight of 54.54 ± 2.49 kg were used and for the performance and economic viability test, 30 pigs with an average weight of 55.47 ± 5.3 kg were used. In both trials, the animals were distributed in five diets: control diet (0), control diet plus the enzyme complex (0E), diet with 5% CM plus the enzyme complex (5E), diet with 10% CM plus the enzyme complex (10E), and a diet with 15% CM plus the enzyme complex (15E). The digestibility coefficients of dry matter (DM), organic matter (OM) and crude protein (CP) reduced with the inclusion of CM with enzyme complex in the diet of pigs in the finishing phase, in contrast to the ether extract (EE), which improved as the inclusion of CM increased. No statistical difference (P > 0.05) was found in the performance when all diets were compared; however, when comparing only the diets that contained the enzyme complex separately, a negative linear effect (P = 0.015) was observed for the feed conversion (FC) in period 2. The diets have no effects on periods 1 and 3. Diets 0, 5E, 10E, and 15E, presented better net income (P = 0.019) in March to May 2018 due to the different levels of inclusion of CM with enzyme complex; in the other evaluated items, there were no statistical differences (P > 0.05). The inclusion of CM and enzyme complex in the diets reduced the digestibility of the dietary components; however, it did not reflect on the performance and was not financially viable in the studied scenario.

Prawirodigdo S, Gannon NJ, Leury BJ, Dunshea FR. Acid-insoluble ash is a better indigestible marker than chromic oxide to measure apparent total tract digestibility in pigs. ANIMAL NUTRITION (ZHONGGUO XU MU SHOU YI XUE HUI) 2021; 7:64-71. [PMID: 33997333 PMCID: PMC8110848 DOI: 10.1016/j.aninu.2020.07.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 05/26/2020] [Accepted: 07/09/2020] [Indexed: 11/17/2022]
Abstract
The aim of this study was to determine the apparent total tract digestibility (ATTD) of nutrients in cottonseed meal (CSM) and soybean meal (SBM) in simple carbohydrate and more complex wheat-based diets using 2 indigestible markers and total faecal collection. Twenty-five Large White × Landrace boars (57.8 kg) were randomly allocated to either a pure wheat diet, 40% CSM or SBM in either a sugar-starch- (1:1) or wheat-based diet for 18 d. Acid-insoluble ash (AIA) and chromic oxide (Cr2O3) were included in all diets as indigestible markers. Diets were offered (1,800 g/d per pig) in 3 meals/d from d 1 to 11 and 8 meals/d from d 12 to 17. On d 9, the pigs were moved to individual metabolism cages to allow total faecal collection. On d 18, the pigs were fed hourly for 8 h. After the 8th meal, pigs were anaesthetized and digesta sampled from the terminal ileum and rectum before lethal injection. There were no differences between ATTD of nitrogen (N) determined using AIA as a marker and measured by total faecal collection. On the other hand, the ATTD of N of diets containing CSM in sugar-starch- or wheat-based diets and the pure wheat diet determined using Cr2O3 as a marker was less (-3.11%, -4.46% and -6.59%; P < 0.001) than that measured by total faecal collection. The ATTD of N determined using AIA as a marker was highly correlated with that measured using total faecal collection (P < 0.001; R 2 = 0.95). Similarly, the ATTD of N determined using Cr2O3 as a marker was correlated with that measured using total faecal collection, although the correlation was not quite as strong as using AIA (P < 0.001; R 2 = 0.87). Also, the slope of the regression line and the intercept were closer to unity and zero for the relationship when the ATTD of N was determined using AIA compared to Cr2O3 as an indigestible marker. The ATTD of organic and dry matter behaved similarly. These data demonstrate that the basal diet and choice of indigestible marker can substantially influence the ATTD and that the use of AIA as an indigestible marker is more suitable than Cr2O3 in digestibility studies in pigs.

Basal diet and indigestible marker influence apparent digestibilities of nitrogen and amino acids of cottonseed meal and soybean meal in pigs. ACTA ACUST UNITED AC 2019; 5:234-240. [PMID: 31528724 PMCID: PMC6737563 DOI: 10.1016/j.aninu.2019.02.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 02/15/2019] [Accepted: 02/27/2019] [Indexed: 11/25/2022]
Abstract
This study was to determine the apparent ileal nitrogen (N) and amino acid digestibilities of cottonseed meal (CSM) and soybean meal (SBM) in simple carbohydrate-based and more complex wheat-based diets. Twenty five Large White × Landrace boars (40.9 kg) were randomly allocated to one of 5 dietary treatments: a wheat diet, 40% CSM in either a sugar:starch (1:1) or wheat-based diet, or 40% SBM in either a sugar:starch or wheat-based diet for 14 d. All diets contained vitamins, minerals, and contained acid-insoluble ash (AIA) and Cr2O3 as indigestible markers. Rations were offered (1,800 g/pig per d) in 3 meals/d on d 1 – 11 and 8 meals/d on d 12 – 13. On d 14, the pigs were fed hourly for 8 h. After the 8th meal, pigs were anaesthetised with isoflurothane, and ileal and faecal digesta sampled from the terminal ileum and rectum before lethal injection of barbiturate. Apparent ileal digestibility (AID) of N was greater (12.1%) when CSM was fed in the wheat-based diet as compared to the simple carbohydrate-based diet, whereas apparent ileal N digestibility of SBM was slightly lower (−4.5%) in the wheat-based diet as compared to the sugar:starch-based diet. Apparent ileal amino acid digestibility generally respondeds similarly to N. Therefore, while there was a wide difference in apparent N and amino acid digestibilities of SBM and CSM when they were fed in the sugar:starch-based diets, these differences were less apparent when they were fed the wheat-based diet. There was an apparent net release of N into the hindgut of pigs fed CSM in both base diets. Conversely, there was quite substantial apparent digestion of N in the hindgut of pigs fed SBM in both base diets. The use of Cr2O3 as an indigestible marker resulted in lower apparent ileal and faecal digestibilities than using AIA, particularly for diets containing CSM. These data demonstrate that the basal diet and choice of indigestible marker can substantially influence the estimate of apparent N digestibility, this response can differ for different protein meals.

Abstract
Background: Herbal medicines have been used in the treatment of liver diseases for a long time. The current study was elaborated to evaluate in vitro and in vivo antioxidant and anti-inflammatory effects of Lotus corniculatus (L. corniculatus) butanolic extract. Methods: The in vitro antioxidant and anti-inflammatory properties of L. corniculatus were investigated by employing DPPH radical scavenging, H2O2 scavenging and BSA denaturation assays. In vivo antioxidant and anti-inflammatory effects of L. corniculatus were evaluated against paracetamol (APAP)-induced hepatitis in rats. L.corniculatus at doses of 100 and 200 mg/kg was administered orally once daily for seven days. Serum transaminases (AST and ALT) and lactate dehydrogenase (LDH), total bilirubin levels, liver malondialdehyde (MDA), reduced glutathione (GSH), glutathione S- transferase (GST) and superoxide dismutase (SOD) levels and inflammatory markers, such as serum C-reactive protein (CRP), circulating and liver myeloperoxidase (MPO) levels were investigated. Further histopathological analysis of the liver sections was performed to support the effectiveness of L. corniculatus. Results:L. corniculatus exhibited strong antioxidant and anti-inflammatory effects in vitro. In the in vivo study, our findings demonstrate that L. corniculatus (100 and 200 mg/kg) administration led to an amelioration of APAP effects on liver histology, liver functions parameters (AST, ALT, LDH, and total bilirubin levels) and liver oxidative stress markers (MDA, GSH, GST and SOD levels). Furthermore, serum CRP, circulating MPO and liver MPO levels were declined by both doses of L. corniculatus extract. The best benefits were observed with 200 mg/kg of L. corniculatus extract. Conclusion: Antioxidant and anti-inflammatory effects of L. corniculatus extract may be due to the presence of active components.

Abstract
In the present study, we investigated the effect of grape seed and skin supplement (GSSS), on lactating dairy ewes' production. Ten dairy pregnant ewes from northern Tunisia were allocated to two groups: control diet (C) and supplemented with 20 % (w/w) GSSS. The experiment lasted for 8 weeks and took place after 2 months of lambing. During the experiment, daily milk yield and milk composition were determined. Supplementation of the diet with GSSS increased milk production (P < 0.001), calcium (P < 0.01), free iron (P < 0.01) and urea content (P < 0.001) but had no effect on milk fat nor protein. From these data, it is concluded that the inclusion of GSSS in sheep diets increased significantly ewes' milk yield.

Abstract
Oilseed meal is an important source of essential amino acids (EAA) for livestock production. It is the second most important ingredient in pig feed after grains. Optimal use of these ingredients requires precise knowledge of amino acid standardized ileal digestibility (SID), which may vary depending on several factors including botanical variety or processing treatments. A meta-analysis was performed in order to derive models for predicting the SID of soybean, cotton and rapeseed meal EAA, based on chemical composition data such as CP, total concentration of each EAA and fibre (crude fibre, ADF and NDF) content. A database of 47 references (224 experimental treatments) was built. A model incorporating processing method of the meals (e.g. cold pressed, expeller pressed, solvent extracted), experimental surgical procedure (T-cannula, re-entrant cannula, post valve T-cannula and ileo-rectal anastomosis) and pig growth stage (BW⩽ or ⩾25 kg) was tested. Results indicated that neither processing nor BW affected EAA SID. NDF was the best predictor of SID (R 2=0.944, 0.836, 0.779, 0.899 and 0.814, respectively, for Lys, Met, Thr, Trp and Val). The total EAA content was the best predictor of digestible content (g/kg diet) for each EAA (R 2=0.990, 0.985, 0.977, 0.985 and 0.978, respectively, for Lys, Met, Thr, Trp and Val). This study shows that routine chemical analyses may be used to predict EAA digestibility with satisfactory accuracy.

Abstract
For Australian and New Zealand dairy farms, the primary source of home-grown feed comes from grazed perennial pastures. The high utilisation of perennial pasture is a key factor in the low cost of production of Australian and New Zealand dairy systems and, hence, in their ability to maintain international competiveness. The major pasture species used are perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.), normally grown in a simple binary mixture. As pasture production has been further driven by increasing use of nitrogen fertiliser and irrigation, farms are getting closer to their economic optimum level of pasture utilisation. Increasing inputs and intensification have also increased scrutiny on the environmental footprint of dairy production. Increasing the diversity of pasture species within dairy swards presents opportunities to further increase pasture utilisation through additional forage production, extending the growing season, improving forage nutritive characteristics and, ultimately, increasing milk production per cow and/or per hectare. Diverse pastures also present an opportunity to mitigate some of the environmental consequences associated with intensive pasture-based dairy systems. A consistent finding of experiments investigating diverse pastures is that their benefits are due to the attributes of the additional species, rather than increasing the number of species per se. Therefore, the species that are best suited for inclusion into dairy pastures will be situation specific. Furthermore, the presence of additional species will generally require modification to the management of dairy pastures, particularly around nitrogen fertiliser and grazing, to ensure that the additional species remain productive and persistent.

Abstract
Foi conduzido um estudo com objetivo de avaliar o uso do farelo de algodão (FA42) na alimentação de suínos, nas fases de crescimento e terminação, seus efeitos sobre o desempenho zootécnico, características de carcaça e viabilidade econômica. Foram utilizados 40 suínos mestiço com peso de 29,7 ± 1,6 aos 52,2 ± 3,6kg para o crescimento e 52,7 ± 2,9 aos 86,9 ± 5,0kg para a terminação. Para cada fase foram formuladas três rações (5, 10 e 15% de FA42). Adicionalmente foi formulada uma ração sem a inclusão de FA42 (0%). Os suínos foram distribuídos em um delineamento em blocos ao acaso com quatro tratamentos e quatro blocos, com quatro repetições por tratamento. Não foram observados efeitos da inclusão de FA42 para as variáveis de desempenho na fase de crescimento, entretanto para a fase de terminação, houve efeito linear crescente dos níveis de inclusão sobre o consumo e conversão alimentar. As características de carcaça e o nitrogênio da uréia plasmática não foram influenciados. Os resultados sugerem que o FA42 pode ser utilizado nas rações de suínos em crescimento em até 15% e em até 10% na terminação ou em substituição próxima de 50% da proteína do farelo de soja, sem prejuízos ao desempenho. Entretanto, o nível de 5% de inclusão do FA42 foi o que apresentou a melhor eficiência econômica.
