Abstract
Ruminal methanogenesis is a major contributor to global environmental pollution in the agriculture sector. Dietary intervention modestly abates enteric methane emissions in ruminants. Therefore, the present experiment was conducted to evaluate the combined effect of dietary oilseeds and phytochemical-rich herbages on enteric methane emission, growth performance, and nutrient utilization in lambs. Forty-eight finisher Malpura lambs were divided into 4 groups (RSZ, RSP, RSLZ, and RSLP) of 12 each in a factorial design. Lambs were fed ad libitum concentrate formulated with roasted soybean (RS) or roasted soybean plus linseed (RSL) along with Ziziphus nummularia (Z) or Prosopis cineraria (P) leaves as roughage sources. Variation in the source of roughage significantly affected feed intake, and it was higher (P < 0.05) in lambs fed Prosopis cineraria leaves (RSP and RSLP). The average daily gain was improved (P < 0.05) by 28.6 and 25.0% in lambs fed Prosopis cineraria, i.e., RSP and RSLP respectively, than those fed Ziziphus nummularia leaves irrespective of concentrate diets. Overall, microbial nitrogen synthesis (MNS) was higher (P < 0.05) in lambs fed roasted soybean (RS) than roasted soybean plus linseed (RSL); however, combination of Prosopis cineraria with both the concentrate diets increased MNS, than the combination of roasted oilseeds and Ziziphus nummularia. No significant interaction was observed in the concentration and proportion of volatile fatty acids by feeding combination of roasted oilseed and tree leaves; however, the proportion of acetic and propionic acid was higher (P < 0.05) in the RSL group compared to RS. Methane emission per kg dry matter intake was reduced (P < 0.05) by feeding Prosopis cineraria leaves regardless of concentrate mixture. As a result, the loss of metabolizable energy through methane emission was lowered by 0.7 and 4.6% when Prosopis cineraria leaves were combined with roasted soybean (RSP) and roasted soybean plus linseed (RSLP), respectively. From the present findings, it can be concluded that combination of Prosopis cineraria leaves either with roasted soybean or roasted soybean plus linseed reduced enteric methane emissions more effectively than Ziziphus nummularia leaves, and the energy saved was transformed into higher body weight gain and improved feed conversion ratio.

Effects of feeding urea-treated triticale and oat grain mixtures on ruminal fermentation, microbial population, and milk production performance of midlactation dairy cows. ANNALS OF ANIMAL SCIENCE 2021.

Abstract
Abstract
The starch content of triticale and oat grains provides much of their readily available energy. Synchronizing energy and nitrogen in the rumen is important in optimizing profitability; for this reason, ammonia processing of these grains was evaluated for its potential to modify ruminal fermentation and to improve milk production performance. A mixture of ground triticale and oats (CONG, at a ratio of 60:40 on a dry matter basis) was treated with urea (5 kg/1000 kg) and urease additive (20 kg/1000 kg) containing 200 g/kg of moisture, for 2 wk (UREG). The urea treatment enhanced the pH and CP content of grains by 34% and 52%, respectively. In a batch culture study, CONG or UREG as the only substrate was incubated in a buffered ruminal fluid. Compared to CONG, UREG increased pH, total VFA concentration, total gas, and disappearance of DM, while reducing CH4 production, whereas NH3 concentration increased and entodiniomorph counts tended to increase. In the in vivo study, cows were randomly allocated to two dietary groups (n = 24) and were offered TMR based on maize and grass silage, containing either 155 g/kg of CONG and 80 g/ kg of soybean meal (CONT) or 155 g/kg of UREG and 59 g/kg of soybean meal (URET) for 31 d. Ruminal fluid was collected (n = 10) using rumenocentesis. The relative abundances of Streptococcus bovis decreased, but Megasphaera elsdenii, methanogens, and ammonia-producing bacteria increased by URET. Entodiniomorph and holotrich counts were decreased by URET. Feeding with URET increased ruminal pH and concentrations of total VFA, acetate, branched-chain VFA, and NH3. Feeding with URET also increased milk yield. These results demonstrate that replacing untreated triticale and oat grains with urea-treated grains can beneficially modulate ruminal microbiota and fermentation, consequently improving production performance and profitability.

JOURNAL OF ANIMAL SCIENCE AND TECHNOLOGY 2021; 63:475-490. [PMID: 34189498 PMCID: PMC8203991 DOI: 10.5187/jast.2021.e50] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Revised: 01/21/2021] [Accepted: 02/25/2021] [Indexed: 01/30/2023]
Abstract
An experiment was conducted to determine the effects of two levels of rumen undegradable protein (RUP) without or with whole or extruded flaxseed on milk yield, milk component, milk fatty acids (FAs) profile and plasma metabolites in transition ewes. Three weeks before and after lambing, seventy-two Baluchi ewes were used in a completely randomized design with a 3 × 2 factorial arrangement of treatments. The treatments contained 1) no flaxseed + 20% RUP (no flaxseed, low RUP [NFLR]); 2) no flaxseed + 40% RUP (no flaxseed, high RUP [NFHR]); 3) 10% whole flaxseed + 20% RUP (whole flaxseed, low RUP [WFLR]); 4) 10% whole flaxseed + 40% RUP (whole flaxseed, high RUP [WFHR]); 5) 10% extruded flaxseed + 20% RUP (extruded flaxseed, low RUP [EFLR]), and 6) 10% extruded flaxseed + 40% RUP (extruded flaxseed, high RUP [EFHR]). Ewes fed 10% extruded flaxseed exhibited higher (p < 0.001) dry matter intake (DMI) and colostrum yield (p < 0.1) compared to other treatments. Two types of flaxseed and RUP levels had no significant effect on milk yield, but milk fat and protein contents decreased and increased in diets containing 40% RUP, respectively. Ewes fed extruded flaxseed produced milk with lower concentrations of saturated fatty acids (SFA) and higher α-linolenic and linoleic acids and also polyunsaturated fatty acids (PUFA) compared to other groups (p < 0.05). During post-lambing, the ewes fed diets containing flaxseed exhibited higher concentration of serum non-esterified FAs (NEFA) compared to diets without flaxseed (p < 0.01). The concentration of serum β-hydroxybutyric acid (BHBA) decreased in the diets containing flaxseed types at pre-lambing, but increased in diets containing extruded flaxseed at post-lambing (p < 0.01). The serum glucose concentration of ewes (pre and post-lambing) which consumed diets containing extruded flaxseed or 40% RUP increased, but blood urea concentration was elevated following supplementation of diet with whole flaxseed or 40% RUP (p < 0.001). In conclusion, utilization of 10% extruded flaxseed in the diets of transition ewes had positive effects on animal performance with favorable changes in milk FAs profile. However, there is no considerable advantage to supply more than 20% RUP level in the diet of transition dairy sheep.

Abstract
The transition period of dairy cattle is characterized by a number of metabolic, endocrine, physiologic, and immune adaptations, including the occurrence of negative energy balance, hypocalcemia, liver dysfunction, overt systemic inflammatory response, and oxidative stress status. The degree and length of time during which these systems remain out of balance could render cows more susceptible to disease, poor reproductive outcomes, and less efficient for milk production and quality. Studies on both monogastrics and ruminants have reported the health benefits of nutraceuticals (e.g. probiotics, prebiotics, dietary lipids, functional peptides, phytoextracts) beyond nutritional value, interacting at different levels of the animal’s physiology. From a physiological standpoint, it seems unrealistic to disregard any systemic inflammatory processes. However, an alternate approach is to modulate the inflammatory process per se and to resolve the systemic response as quickly as possible. To this aim, a growing body of literature underscores the efficacy of nutraceuticals (active compounds) during the critical phase of the transition period. Supplementation of essential fatty acids throughout a 2-month period (i.e. a month before and a month after calving) successfully attenuates the inflammatory status with a quicker resolution of phenomenon. In this context, the inflammatory and immune response scenario has been recognized to be targeted by the beneficial effect of methyl donors, such as methionine and choline, directly and indirectly modulating such response with the increase of antioxidants GSH and taurine. Indirectly by the establishment of a healthy gastrointestinal tract, yeast and yeast-based products showed to modulate the immune response, mitigating negative effects associated with parturition stress and consequent disorders. The use of phytoproducts has garnered high interest because of their wide range of actions on multiple tissue targets encompassing a series of antimicrobial, antiviral, antioxidant, immune-stimulating, rumen fermentation, and microbial modulation effects. In this review, we provide perspectives on investigations of regulating the immune responses and metabolism using several nutraceuticals in the periparturient cow.

Abstract
There are few studies on the concentrations and emission characteristics of ammonia (NH3) and hydrogen sulfide (H2S) from Chinese dairy farms. The purpose of this study was to calculate the emission rates of NH3 and H2S during summer and to investigate influencing factors for NH3 and H2S emissions from typical dairy barns in central China. Eleven dairy barns with open walls and double-slope bell tower roofs from three dairy farms were studied. Five different locations in each barn were sampled both near the floor and at 1.5 m above the floor. Concentrations of NH3 and H2S were measured using the Nessler’s reagent spectrophotometry method and the methylene blue spectrophotometric method, respectively. NH3 concentrations varied between 0.58 and 4.76 mg/m3 with the average of 1.54 mg/m3, while H2S concentrations ranged from 0.024 to 0.151 mg/m3 with the average of 0.092 mg/m3. The concentrations of NH3 and H2S were higher during the day than at night, and were higher near the ground than at the height of 1.5 m, and were higher in the manure area than in other areas. NH3 and H2S concentrations in the barns were significantly correlated with nitrogen and sulfur contents in feed and manure (P < 0.05), and with temperature inside the barns (P < 0.05). Calculated emission rates of NH3 ranged from 13.8 to 41.3 g NH3/(AU·d), while calculated emission rates of H2S ranged from 0.15 to 0.46 g H2S/(AU·d). These results will serve as a starting point for a national inventory of NH3 and H2S for the Chinese dairy industry.

Abstract
The Australian dairy sheep industry is small and mostly based on a natural grass grazing system, which can limit productivity. The current study tested different plant oil-infused and rumen protected polyunsaturated fats and their interactions with sire breeds to improve lactation traits and body condition scores (BCS) of ewes grazing low quality pastures. It was hypothesised that supplementing lactating ewe's diets with plant-derived polyunsaturated oils would improve milk production and composition without compromising BCS. Sixty ewes (n = 10/treatment) in mid-lactation, balanced by sire breed, parity, milk yield, body condition score, and liveweight, were supplemented with: (1) control: wheat-based pellets without oil inclusion; wheat-based pellets including; (2) canola oil (CO); (3) rice bran oil (RBO); (4) flaxseed oil (FSO); (5); safflower oil (SFO); and (6) rumen protected marine oil containing eicosapentaenoic acid and docosahexaenoic acid (RPO). Except for the control group, all supplementary diets included the same level of 50 mL/kg DM of oil and all diets were isocaloric and isonitrogenous. Experimental animals were grazed in the same paddock with ad libitum access to pasture, hay, and water during the 10-week study. RPO was the most effective diet that enhanced milk, fat, and protein yields by approximately 30%, 13%, and 31%, respectively (p < 0.0001). A significant increase in milk production was also observed with CO, RBO, and SFO treatments (p < 0.0001). Breed significantly influenced animal performance with higher milk yields recorded for crossbred Awassi × East Friesian (AW × EF) (578 g/day) vs. purebred Awassi (452 g/day) (p < 0.0001). This study provides empirical evidence for the use of rumen-protected and plant-derived oil-infused pellets as supplements under low quality pasture grazing conditions to improve the production performance of purebred Awassi and crossbred AW × EF ewes.

Abstract
The aim of the present research was to evaluate the effects of protein level and flaxseed supplementation on the yield and quality of buffalo milk. In particular, the fatty acid profile of milk from buffalo cows subjected to different diets has been investigated. A 2×3 factorial design was tested with buffalo cows receiving 2 dietary crude protein (CP) and 3 flaxseed (FS) supplementation levels. Treatments were (1) low dietary CP level [12% of dry matter (DM)] and no flaxseed supplementation (LP); (2) low dietary CP level (12% of DM) and low flaxseed supplementation (500g/d) (LPFS500); (3) low dietary CP level (12% of DM) and moderate flaxseed supplementation (1,000g/d) (LPFS1000); (4) moderate dietary CP level (15% of DM) and no flaxseed supplementation (MP); (5) moderate dietary CP level (15% of DM) and low flaxseed supplementation (500g/d) (MPFS500); and (6) moderate dietary CP level (15% of DM) and moderate flaxseed supplementation (1,000g/d) (MPFS1000). Milk protein and casein were affected by flaxseed supplementation being higher in MP, intermediate in LP, and lower in flaxseed-supplemented diets. However, the results from the present study highlighted that low protein diets sustained milk yield, protein, and casein synthesis in milk when whole flaxseed was administered. Short-chain fatty acids, in particular C8:0 and C10:0, were the lowest in milk from buffalo cows fed the highest level of flaxseed supplementation. Medium-chain fatty acids were the lowest in FS1000, intermediate in FS500, and the highest in the HP and LP groups. Long-chain fatty acids were the highest in FS1000, intermediate in FS500 groups, and the lowest in milk from buffalo receiving no flaxseed supplementation. Protein level of the diet influenced the percentage of C18:0, which was higher in MP than LP groups. Total conjugated linoleic acid content evidenced the same trend of long-chain fatty acids, with an increase of about 7% in FL500 and of 22% in FL1000 than the control. Apart from protein level of the diet, atherogenic index, thrombogenic index, and n-6/n-3 were the lowest in FS1000 groups; thrombogenic index and n-6/n-3 were intermediate in milk from animals receiving FS500. Nutritional value of the acidic profile in buffalo milk is influenced by flaxseed supplementation, and its improvement reflects the level of dietary flaxseed supplementation.

Abstract
The overall objective of this study was to calculate the amount of nitrogen (N) that cattle feed must contain in order to utilise the potential supply of utilisable crude protein at the duodenum provided by their energy intake without incurring a negative N balance, that is, without having to break down body protein. For this purpose, the literature was screened for measurements of net degradation and renal excretion of urea as well as N balances (N intake, faecal N and urinary N) in ruminants (cattle, sheep and goats) fed diets with varying N concentrations. Irreversible loss of N from the body urea pool increased with increasing N intake, but net degradation of urea as a proportion of irreversible loss decreased concurrently. Faecal N appeared not to be influenced by N intake and exceeded 11 g/kg dry matter intake (DMI) only in 7% of the data sets available. Urinary non-urea-N rarely exceeded 4 g/kg DMI and appeared independent of N intake. Urinary urea-N showed a clear dependence of N intake, and it is concluded that 1 g N/kg DMI is sufficient for compensating inevitable N losses in the form of urinary urea. In conclusion, ruminant rations should contain the following N concentrations (per kg DM) to account for obligatory losses: 11 g for compensating losses as faecal N, 4 g for compensating losses as urinary non-urea-N and 1 g for compensating inevitable losses as urinary urea-N. The derived recommendations should be helpful for limiting N excretion where this is desirable for ecological reasons.

ASIAN-AUSTRALASIAN JOURNAL OF ANIMAL SCIENCES 2013; 26:1111-8. [PMID: 25049891 PMCID: PMC4093220 DOI: 10.5713/ajas.2013.13027] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/11/2013] [Revised: 03/27/2013] [Accepted: 03/12/2013] [Indexed: 11/27/2022]
Abstract
The objective of this study was to determine the effects of whole linseed supplementation on performances and milk fatty acid composition of dairy cows. Thirty six Holstein Friesian crossbred lactating dairy cows were blocked by milking days first and then stratified random balanced for milk yields and body weight into three groups of 12 cows each. The control group received 300 g of palm oil. The second group was supplemented with 344 g/d of top-dressed whole linseed plus 150 g of palm oil and the third group was supplemented with 688 g/d of top-dressed whole linseed. All cows also received ad libitum grass silage (Brachiaria ruziziensis), had free access to clean water and were individually housed in a free-stall unit and individually fed according to treatments. Residual feeds were collected on 2 consecutive days weekly and at the end of the experiment. Feed samples were pooled to make representative samples for proximate and detergent analyses. Daily milk yields were recorded. Milk samples were collected on 2 consecutive days weekly. Live weights were recorded at the start and at the end of the experiment. Milk samples were taken on d 56 of the experiment and subjected to milk fatty acid composition. The results showed no statistical significant differences in intakes, live weight change, milk yields and milk compositions, however, C18:1, C18:3 and unsaturated FAs were increased while saturated FAs were reduced by whole linseed supplementation. It is recommended that the addition of 300 g/d oil from whole linseed could be beneficial to lactating dairy cows in early lactation.

Abstract
BACKGROUND The aim of this study was to examine the influence of linseed variety on the concentration of cow's milk constituents, particularly fatty acids. The experiment was conducted on 30 Polish Holstein Friesian cows whose diet was supplemented with two varieties of crude linseed, Opal and Szafir. RESULTS After 21 days of linseed supplementation, the Szafir variety proved to be a better supplement than the Opal variety, particularly in relation to the concentration of saturated fatty acids, C20:5 (69.2% higher) and C22:6 (147.1% higher) and also because of improved chemical composition of the milk (19.7% higher fat, 2.9% higher protein and 39.9% higher casein content). CONCLUSION Linseed variety significantly influenced the lipid fraction level and the basic chemical composition of cow's milk. Linseed variety should therefore be taken into consideration in subsequent experiments in addition to the quantity and physical form of linseed. The results showed that the use of a diet supplemented with linseed, especially the Szafir variety, was effective in reducing saturation, atherogenic and thrombogenic indices, yielding benefits for consumers by improving the nutritional quality of cow's milk.

Abstract
The objective of the study was to determine the effects of adding Gln or Gln in combination with flaxseed to the diet on milk production and immune response of dairy cows during the summer season. The experiment lasted 60 d and involved 24 lactating Friesian cows, divided into 4 groups of 6 animals, fed as follows: (1) control diet, (2) control diet supplemented with 160 g/d of rumen-protected Gln (GLN), (3) control diet supplemented with whole flaxseed (FS), and (4) control diet supplemented with both flaxseed and Gln (FS+GLN). Individual milk samples were collected at morning and afternoon milkings every 14 d throughout the experiment and analyzed for pH, total protein, casein, fat, lactose content, and somatic cell count. Milk samples were also analyzed for milk fatty acid profile. Monitoring of cow immune responses was carried out by the determination of lymphocyte response to phytohemagglutinin in vivo on each animal by measurement of skin-fold thickness at site of phytohemagglutinin injection. A humoral response to chicken egg albumin (OVA) was determined following a subcutaneous injection with OVA. Plasma samples were measured for the presence of anti-OVA IgG, IL-1β, IL-6, and IL-10. Results indicate that Gln administration can be used to support dairy cows under a hot climate, because Gln was able to enhance cow immune reactions in terms of a strengthening of cell-mediated immune response, which is weakened in cows under heat stress. In addition, an increase in milk and fat, protein, and casein yields in response to GLN was observed. When administrating Gln in combination with flaxseed, milk production and milk fat profile did not further increase compared with FS milk, and a reduction in immune reactivity compared with FS and GLN cows was found.

Abstract
Flaxseed hull, a co-product obtained from flax processing, is a rich source of n-3 fatty acids but there is little information on digestibility of its nutrients by dairy cows. Four rumen-cannulated multiparous Holstein cows averaging 665 ± 21 kg of body weight and 190 ± 5 d in milk at the beginning of the experiment were assigned to a 4 × 4 Latin square design with four 28-d experimental periods to determine the effects of feeding monensin and flaxseed hulls on total tract apparent digestibility of nutrients and fatty acids. The four treatments were: (1) diet CO: control with neither flaxseed hulls nor monensin added; (2) diet FH containing 19·8 g flaxseed hulls/100 g dry matter (DM); (3) diet MO with 16 mg monensin/kg DM; (4) diet HM containing 19·8 g flaxseed hulls/100 g DM and 16 mg monensin/kg DM. Diets provided similar amounts of protein and net energy of lactation. Digestibility of crude protein was higher for diets containing flaxseed hulls and for diets supplemented with monensin. Flaxseed hulls supplementation decreased digestibility of acid and neutral detergent fibre. Significantly higher digestibility of ether extract and individual fatty acids was observed for treatments with flaxseed hulls compared with treatments without flaxseed hulls. A combination of flaxseed hulls and monensin did not result in better fatty acid digestibility than when feeding only flaxseed hulls.
