The present study was conducted to determine the effects of inclusion macauba cake, from biodiesel processing, on profile rumen protozoa Santa Ines lambs. Twenty-four lambs were randomized in block design supplemented with cake at 0, 100, 200, and 300 g/kg dry weight diet. Concentrations small, medium, large had quadratic relationships maximum occurring 100 g/kg. High genus diversity occurred fluid that did not feed comprising 13 genera. However, only genera Isotricha, Charonina, Entodinium,...
Assuming that acetic acid plays a minor role in the development of ruminal epithelium preweaning dairy calves, fiber supply for growing calves has been neglected. More research done on including starch and nonfibrous carbohydrates solid feed calves. Accordingly, requirement these is not well known, as diet recommendations vary greatly. Hence, elucidating effects from long particle sizes may be essential helping overcome transition challenge during weaning. Forty-five Holstein were used...
Lipid supplementation through vegetable oils in diets for ruminants can be a nutritional strategy to increase energy density, manipulate ruminal fermentation and change the physicochemical composition sensorial properties of meat. This study evaluated optimal dietary inclusion palm kernel oil (PKO) Nellore bulls on meat quality. The consisted 0.0, 11.5, 23.0, 34.6 g/kg dry matter (DM) PKO levels. did not influence centesimal composition, pH, color indices, water holding capacity, cooking...
β-glucans has been reported to be associated with many health-promoting and improvements in animal performance, however, information about their effects on the bacterial community remains unknown. This study aimed investigate how addition of can affect fecal possible consequences growth health. For this, newborn Holstein calves (n = 14) were individually housed tropical shelters blocked according sex, date, weight at birth randomly assigned one following treatments: (1) Control: milk...
Studies have shown that β-glucans extracted from the cell wall of cereals, algae, and yeasts been associated with improved immune function. However, it is unknown whether algae β-glucan supplementation affects performance, blood metabolites, or counts cells in dairy calves. The objective this randomized clinical trial was to evaluate milk replacer calves fed 6 L/d growth performance fecal status altered metabolite profile. In trial, we enrolled Holstein (n = 34) at birth (body weight 36.38 ±...
The aim of this study was to evaluate the effects inclusion palm kernel oil (PKO) in a lamb diet on nutrient intake, digestibility, ingestive behavior, nitrogen balance, blood metabolites, rumen fermentation parameters, and animal performance. Three experimental trials were conducted. treatments consisted varying levels PKO included diet, with PKOzero = no inclusion, PKO1.3 1.3% addition, PKO2.6 2.6% PKO3.9 3.9% PKO5.2 5.2% based total dry matter (DM) diet. With linear decreases DM (p <...
Abstract The liquid diet composition can affect dairy calves' performance and diarrhea incidence. effect of three diets on performance, incidence diarrhea, microbial community during occurrence in calves were evaluated. At birth, 35 (20 male 15 female) randomly assigned to one treatments—refrigerated whole milk (WM), acidified (AWM), replacer (MR). Intake, fecal score, rectal temperature evaluated daily, blood parameters weekly the preweaning period. Fecal samples from diarrheic collected,...
The purpose of this study was to quantify, identify and compare the protozoa populations in rumen different ages beef cattle raised tropical pastures during dry season. We sampled ruminal fluid 36 steers, 34 cows 30 calves, all crossbred Nelore. diluted 10% formaldehyde solution decimal dilutions were prepared saline quantify small, medium large Sedgewick Rafter chamber. A total 135,800 evaluated an optical microscope using Lugol's iodine coloration genera classified according morphological...
The study aimed to evaluate the effect of maternal or formulated transition milk with colostrum powder on performance and health dairy calves. After receiving 12% their birth weight in high-quality colostrum, 36 Holstein calves (17 males 19 females) were blocked according sex, date (29.16 kg ± 1.34) randomly distributed into three treatments: (1) Milk: supplying 4 L/d whole (WM) for days (n = 12); (2) Transition (TM): (3) Formulated (FTM): enriched 280 g/d powder, 12). Daily feeding was...
This study aimed to evaluate the effect of feeding milk replacer (MR) with varying levels lactose and increased supply total solids (from 750 960 g/d) on performance, blood metabolites, health Holstein male calves during preweaning period.
Feeding a liquid diet to the newborn calf has considerable implications for developing intestinal microbiota, as its composition can shift population highly adapted microbiota. The present work evaluated 15 Holstein calves individually housed and fed one of three diets: I – whole milk ( n = 5), II replacer (22.9% CP; 16.2% fat; diluted 14% solids; 5) III acidified pH 4.5 with formic acid 5). All animals received 6 L diet, divided into two meals, being weaned at week 8 life. Calves also had...
Vegetable oils can be used to increase energy density in diets; manipulate rumen fermentation; and alter the capacity for degradation, digestion absorption of nutrients. Two experiments were conducted evaluate palm kernel oil (PKO) diet confined bulls with inclusion 0.0, 11.5, 23.0 34.6 g PKO/kg dry matter (DM). The first experiment evaluated nutrient intake, performance, ingestive behavior carcass characteristics. In second experiment, steers crossbred a ruminal cannula digestibility,...
The aim of this study was to evaluate the age and post-prandial variations in selected metabolite concentration that may indicate a shift metabolism, from pre- functional ruminant, according liquid diet fed dairy calves. Sixteen newborn Holstein calves were included randomized complete block experimental design. individually housed 6 L/d with whole milk (WM) or replacer (MR). Blood samples collected weekly at 0 h (before feeding), 1 h, 2 4 8 after morning feeding glucose, β-hydroxybutyrate...
This research was conducted to investigate the effect of live and inactive sugarcane yeast on beef cattle voluntary intake, apparent digestibility nutrients, ruminal pH, volatile fatty acids (VFA) concentrations, ammonia. Five rumen-cannulated Nellore heifers were distributed in a 5×5 Latin square design, with five experimental periods 15 days, seven days for adaptation additives remaining data records sampling. Total mixed ration (TMR) composed by corn silage (20%) concentrate (80%) based...
We aimed to determine the optimal inclusion level of sunflower cake (0, 90, 180, and 270 g/kg total DM) as a partial replacement soybean meal corn ground in young bulls’ diets by examining nutrient intake digestibility, ingestive behavior, nitrogen balance, metabolic serum profile, growth performance, carcass traits. Thirty-two intact Nellore bulls (BW 374 ± 42.5) were distributed completely randomized design. The experiment lasted 90 days. final BW animals was 515.25 24.7. There linear...
This study aimed to evaluate the performance and metabolic changes in dairy calves supplemented with lysine methionine milk replacer (MR) or starter concentrate (SC). Male Holstein (n = 45) were blocked distributed Control without supplementation (1) and; Lysine Methionine achieve an intake of 17 5.3 g/d SC (2) MR (3). was fed (6 L/d) until 8th week life when weaning occurred. Calves followed 10th age. Feed measured daily. Weight body measurements registered weekly. Blood samples collected...
