The objective of this trial was to evaluate the increasing levels of soybean oil (0, 1.5, 3.0, 4.5, 6.0, and 7.5% of diet dry matter), ethanolic extract of propolis (0, 1.0, 2.0, 4.0, 8.0, and 12.0 mL/animal/day) and ground crude propolis (0, 0.5, 1.0, 2.0, 4.0, and 6.0 g/animal/day) on intake and ruminal metabolism (pH, ammonia N, VFA, and specific activity of ammonia production) in dairy goats. Six ruminally fistulated female Alpine goats were used in a completely randomized design […]

Data consisting of 172,304 test-day records of first lactation Holstein cows were used to evaluate non-genetic effects on Somatic Cell Count (SCC) and Somatic Cell Score (SCS). Milk samples were collected in Holstein herds supervised by the Dairy Herd Analysis Program, at Paraná State, Brazil, between January 1983 and December 1998. The statistical models included the fixed effects of region (Reg), number of milkings (NM), days in milk (DIM), age of cow (AC), month of test-day (MTD), days of storaging […]

Eight crossbred steers fitted with ruminal and duodenal cannulas were randomly assigned to two replicated 4 x 4 Latin squares to evaluate the effects of crude protein (CP) levels on microbial protein synthesis efficiency and in situ degradability of nutrients. Animals received a control diet containing Tifton 85 bermudagrass hay or the control diet supplemented with urea, soybean meal or corn gluten meal-60. Ruminal pH and concentration of ruminal ammonia (NH3-N) were determined in the ruminal fluid at 0 (pre-feeding), […]

The objective of this trial was to evaluate carcass characteristics, cuts yield, tissues proportion, and chemical composition and fatty acid profile of the Longissimus dorsi of feedlot kids fed diets, in which soybean hulls (SH) replaced ground corn grain (GCG). Fifteen Boer x Saanen male kids were assigned to a completely randomized design (five animals per treatment) and slaughtered at 33.82 ± 4.40 kg of body weight. Diets were composed by star grass hay (Cynodon spp), soybean meal, GCG and/or […]

The objective of this trial was to investigate the effect of heterosis and genetic group on the yield and weight of internal organs and gastrointestinal tract (GIT) of feedlot purebred (Charolais C and Nellore N) and crossbred steers from second (G2) (¾C ¼N and ¾N ¼C), third (G3) (5/8C 3/8N and 5/8N 3/8C) and fourth (G4) (11/16C 5/16N and 11/16N 5/16C) generations of rotational crossbreeding slaughtered at 23 month of age. Crossbred steers from G2, G3 and G4 had, respectively, […]

The objective of this trial was to evaluate the compensatory growth and biometrical measurements on lambs feed restricted or ad libitum fed. In the first of two periods of 60 days, 18 7/8 Ile de France x 1/8 Ideal female lambs were assigned to three treatments in a completely randomized design as follows: 1) no feed restriction (ad libitum fed), 2) 30% of feed restriction or 3) 60% of feed restriction calculated as proportion of the ad libitum fed group […]

This trial was carried out to evaluate the influence of defoliation intensities (10 and 20 cm stubble height) and defoliation frequencies (three cut intervals based on the appearance of 5, 7 and 9 leaves/tiller after each defoliation event) on the morphogenetic and structural traits, tillering and herbage production of Brachiaria brizantha cv Marandu swards. Treatments were allocated to experimental units according to a completely randomized design, in a 2 x 3 factorial arrangement, with three replications, in a total of […]

The objective of this trial was to investigate intake and apparent digestibility of nutrients on goats fed one of the following chopped grass hays: pearl millet (PMH), sudangrass (SH), elephantgrass (EH) or two cultivars of forage sorghum (FSH1 and FSH2). Twenty-five goats averaging 18 months of age and 19.5 kg of body weight were assigned to a completely randomized block design with five treatments and five replicates. DM intake (DMI), expressed as percentage of body weight (% BW), did not […]

The work aimed to evaluate the effect of the irrigation on the production of biomass and the nutritional value of Panicum maximum, Jacq. cv. Mombaça and Pennisetum purpureum Schum, cv. Napier. Four treatments were tested, consisting of the combination of irrigation levels and two forages. A split-plot arrangement in time and space in a complete randomized block design was used, with more than one observation per treatment, per block. The forages were evaluated under rotational stocking, using F1 European-zebu steers, […]

Four bulls fitted with ruminal cannula were used in a 4 x 4 Latin square design to evaluate the effects of different ruminally inoculated additives on the degradation kinetics of DM, CP, and NDF of corn silage (CS). The treatments were: control CS incubated in rumen with no additive; LB – CS incubated in rumen inoculated with five grams of dehydrated and lyophilized ruminal and intestinal bacteria (Ruminobacter amylophilum: 3.0 x 1011 ufc/kg; Fibrobacter succinogenes: 3.0 x 1011 ufc/kg; Succinovibrio […]
