The objective of this study was to evaluate whether providing chitosan (CHI) cows fed diets supplemented with whole raw soybeans (WRS) would affect the nutrient intake and digestibility, ruminal fermentation bacterial populations, microbial protein synthesis, N utilization, blood metabolites, milk yield composition dairy cows. Twenty-four multiparous Holstein (141 ± 37.1 d in milk, 38.8 6.42 kg/d yield; mean SD) were enrolled a 4 × Latin square design experiment 23-d periods. Cows blocked...
Our objective was to evaluate the effects of providing increasing levels chitosan on nutrient digestibility, ruminal fermentation, blood parameters, nitrogen utilisation, microbial protein synthesis, and milk yield composition lactating dairy cows. Eight rumen-fistulated Holstein cows [average days in lactation = 215 ± 60.9; average bodyweight (BW) 641 41.1 kg] were assigned into a replicated 4 × Latin square design, with 21-day evaluation periods. Cows be provided four chitosan, placed...
This study aimed to evaluate of productive characteristics in integrated livestock-crop systems with or without winter grazing and fertilization strategies. The experimental design used was a randomized complete block split plots (3 replications per treatment). Treatments were composed four strategies (COMB = combination for both soybeans pasture applied during the phase; FSBP REC recommended fertilizations soybean their respective phases TRAD traditional recommendation, N phase P K...
Chitosan (CHI) is a derivative of the biopolymer chitin, found in high amounts shell wastes crustaceans, and has antimicrobial properties. The objective this study was to determine influence increasing doses CHI for grazing cattle on nutrient intake total apparent digestibility, ruminal fermentation parameters, microbial protein synthesis, nitrogen utilization, urea creatinine metabolism. Five rumen cannulated crossbred steers [3.6 mo 300 ± 25 kg live weight (LW), mean SD] were used 5 ×...
An experiment was conducted to evaluate the effects of inorganic trace minerals (TM) and reduced levels TM by using proteinate forms Co, Zn, Mn, Cu, Se-yeast in diets transition cows on performance, concentrations colostrum, plasma, liver, blood metabolites, antioxidant status, peripheral neutrophil activity, oocyte quality. Thirty-two Holstein (22 multiparous 10 primiparous cows) were enrolled this study from 30 d before expected calving date 56 DIM. Cows blocked according body condition...
The aim of this study was to evaluate the effects different anti-mycotoxin feed additives on concentration mycotoxins in milk, urine, and blood plasma dairy cows fed artificially multi-mycotoxin-contaminated diets. Secondarily, performance, total-tract apparent digestibility nutrients, parameters were evaluated. Twelve multiparous (165 ± 45 d 557 49 kg body weight, 32.1 4.57 kg/d milk yield at start experiment) blocked according parity, yield, days used a 4 × Latin square design experiment...
This study was undertaken to determine the effects of chitosan and whole raw soybean on nutrient intake total tract digestion, nitrogen utilization, microbial protein synthesis, blood metabolites, energy balance dairy heifers. Twelve Jersey heifers (6±0.5 months age 139.50±25.56 kg live weight; mean ± standard deviation) were randomly assigned a replicated Latin square design with 2 × factorial arrangement. The experimental period consisted 14 days adaptation diets, six sampling, five...
Ruminants have a unique metabolism and digestion of unsaturated fatty acids (UFA). Unlike monogastric animals, the acid (FA) profile ingested by ruminants is not same as that reaching small intestine. The objective this study was to evaluate whole raw soybeans (WS) in diets replacer for calcium salts (CSFA) terms UFA abomasal digesta early- mid-lactation cows. Eight Holstein cows (80 ± 20 d milk, 22.9 0.69 kg/d milk yield, 580 kg body weight; mean standard deviation) with ruminal cannulas...
Sugarcane is relatively affordable in subtropical regions and can be used as a forage source for cattle; however, its low fiber degradation the rumen may impair diet digestibility animal performance. The objective of this study was to evaluate influence fibrolytic enzyme product dairy heifers fed either corn silage or sugarcane silage-based diets on nutrient intake digestibility, eating behavior, energy N utilization, ruminal fermentation, microbial protein synthesis, blood metabolites....
The objective of this experiment was to quantify the effects feeding polymer-coated slow-release urea on nutrient intake and total tract digestion, milk yield composition, balances, ruminal fermentation, microbial protein synthesis, blood parameters in dairy cows. Sixteen Holstein cows (580±20 kg live weight (mean ± standard deviation); 90 180 days (DIM); 28 kg/d average yield) were used a replicated 4 × Latin square experimental design. animals assigned each according DIM. randomly...
Two experiments were carried out to evaluate a blend of essential oils (EO) combined with amylase as an alternative ionophores and its potential for reducing the use antibiotics in dairy industry. In experiment 1, 8 rumen-cannulated Holstein cows (576 ± 100 kg body weight, 146 35 d milk, 35.1 4.0 kg/d milk yield at start experiment) assigned 4 × Latin square 21-d periods determine influence feed additives on total apparent digestibility nutrients, ruminal fermentation, N utilization,...
Peppers (Capsicum spp.) contain capsaicin, an organic compound with a group of alkaloids that has shown thermoregulation properties in humans and mice, may influence glucose lipid metabolism ruminants. An experiment was conducted to evaluate different doses feed additive containing encapsulated pepper on milk yield composition, dry matter intake, sorting index, total-tract apparent digestibility nutrients, purine derivatives excretion, serum concentrations urea-N glucose, N respiration rate,...
Summary Whole oilseeds such as soya beans have been utilized in dairy rations to supply additional fat and protein. However, antinutritional components contained beans, trypsin inhibitors haemagglutinins (lectins) may alter digestibility of nutrients consequently affect animal performance. The objective the present experiment was quantify effect different levels whole raw diets cows on nutrient intake, total tract digestion, balances milk yield composition. Sixteen mid late‐lactation (228 ±...
