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...
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,...
Exogenous enzymes are added to diets improve nutrient utilization and feed efficiency. A study was conducted evaluate the effects of dietary exogenous enzyme products with amylolytic (Amaize, Alltech) proteolytic (Vegpro, activity on performance, excretion purine derivatives, ruminal fermentation dairy cows. total 24 Holstein cows, 4 which were ruminally cannulated (161 ± 88 d in milk, 681 96 body weight, 35.2 5.2 kg/d milk yield), blocked by yield, days then distributed a replicated × Latin...
This study aimed to evaluate the effects of replacing corn silage (CS) with whole-plant soybean (SS) in dairy cow diets on nutrient intake and apparent total-tract digestibility, rumen fermentation, milk yield, composition fatty acid profile milk, serum metabolites, feeding behavior. Twenty-four Holstein cows were enrolled a replicated 4 × Latin square experiment (21 d-periods), samples data collected during last 7 d each period. Treatments consisted control diet (CON) 480 g/kg DM CS, SS...
Dry malt extract (DME) has been used in animal nutrition as an alternative source of rapidly fermentable carbohydrate. An experiment was conducted to evaluate the partial replacement ground corn with DME diets dairy cows on apparent digestibility, ruminal fermentation, predicted rumen microbial protein supply, N excretion, serum urea-N concentration, and milk yield composition. Twenty-eight Holstein (35.3 ± 5.88 kg/d 148 78 d milk), 4 which were cannulated, blocked according presence...
Lactation diets dependent on rumen undegradable protein (RUP) sources derived from soybean meal (SBM) products are generally high in Lys and poor Met. We conducted an experiment to evaluate the effects of increasing dietary RUP altering digestible AA supply by inclusion heat-treated (HTSBM) or high-protein corn dried distillers grains with soluble (DDGS) performance mid-lactation dairy cows. Twenty-four Holstein cows (200 ± 40 d milk 30.0 3.92 kg/d yield) blocked according parity, yield,...
This study was conducted to evaluate the effects of live or autolyzed yeast supplementation on dairy cow performance and ruminal fermentation. Two experiments were performance, feed sorting, total-tract apparent digestibility nutrients, purine derivatives excretion, N utilization, fermentation, abundance specific bacterial groups in rumen. In Exp. 1, 39 Holstein cows (171 ± 40 d milk 32.6 5.4 kg/d yield) blocked according parity, days milk, yield randomly assigned following treatments:...
This study evaluated the effects of homolactic bacteria and molasses (MOL) in whole-plant soybean silage on dry matter (DM) losses, content organic acids, bromatological composition, situ degradation DM aerobic stability. Mini-silos (n = 200) were blocked 5) by phenological stage assigned into a 2×2 factorial treatment arrangement with 2 levels microbial inoculation (INO, 0 or 105 colony forming units Lactobacillus plantarum Pediococcus pentosaceus per kg fresh forage) powdered MOL (0 40...
Introdução: Aditivos fitogênicos podem ser inclusos na dieta de vacas lactantes para melhorar desempenho produtivo e substituir a utilização ionóforos.Sua associação outros aditivos pode contribuir incrementação dos resultados produtivos.Objetivos: avaliar efeitos da implementação compostos fitogênicos, associados ou não leveduras minerais orgânicos em lactação sob consumo digestibilidade nutricional.Metodologia: Foram utilizadas 39 raça Holandesa com 201,3±70,0 dias lactação; 651±36,1kg...
