The study was carried out with the objective to evaluate the effects of the inclusion of the wheat bran (WB) with or without supplementation of an enzymatic complex (EC) on the performance of semi-heavy hens in the egg-production phase. A total of 288 Lohmann Brown pullets were used, distributed to a completely randomized design in 4 × 2 factorial arrangement, composed by four WB levels (0, 3, 6 and 9%) in the ration and enzymatic complex supplementation (0 or 100g/100 […]

Twelve Nellore of three sexual categories (four heifers, four bulls and four steers) averaging 15 months of age and body weight of 235, 249, and 239 kg, respectively, were assigned to a completely randomized design with a 2 × 3 factorial arrangement (two levels of concentrate – 25 or 50% and three sexual categories) to evaluate intake, partial and total digestibility of nutrients, microbial protein synthesis and ruminal metabolism. The collection of ruminal fluid was done before and at 2, […]

Eight hundred Nile tilapia larvae with two days old were used to evaluate the inclusion of soybean meal in diets fed Nile tilapia during the sex reversion period (30 days). The experiment was analyzed as a completely randomized blocks, with four treatments and four replications. A net tank with 50 larvae was considered an experimental unit. The treatments were formulated to be isoprotein and isonitrogenous (38.6% of digestible protein and 3,800 kcal/kg of digestible energy), with increasing levels of soybean […]

A greenhouse experiment was carried out during the Spring 2004 aiming to evaluate Panicum maximum cv. Tanzania root system as related to the combined supply of K and Mg in nutrient solutions. A randomized block design was used, with four replications, in an incomplete 52 factorial experiment with 13 combinations between K and Mg fertilization rates, in mmol/L: 0.4K/0.05Mg; 0.4K/1.35Mg; 0.4K/2.65Mg; 3.2K/0.70Mg; 3.2K/2.00Mg; 6.0K/0.05Mg; 6.0K/1.35Mg; 6.0K/2.65Mg; 8.8K/0.70Mg; 8.8K/2.00Mg; 11.6K/0.05Mg; 11.6K/1.35Mg, and 11.6K/2.65Mg. Roots were collected after the second harvest of […]

Genetic divergence among three lineages of meat-type hens from the Genetic Breeding Program of the Universidade Federal de Viçosa was evaluated for the following traits: days at first egg (DPPO), egg production rate (TP) from 22nd to 56th week, body weight on the 32nd (PMI1), on 40th (PMI2), at 48th (PMI3), at 56th (PMI4) and at the 64th week (PMI5), egg weight on the 32nd (PMO1), on 40th (PMO2), at 48th (PMO3), at 56th (PMO4) and at the 64th week […]

The objective of this trial was to study the effects of substituting corn silage by cassava foliage silage in the diets of non lactating, pregnant dairy cows. The levels of substitution of corn silage by cassava foliage silage were 0, 20, 40 and 60%. Intake and apparent digestibilities of dry matter, organic matter, crude protein, neutral detergent fiber, total carbohydrates, no fiber carbohydrates were evaluated, and pH and ruminal ammonia nitrogen before and 2, 4, 6 and 8h after the […]

The effect of feeding grain sorghum silage, sweet sorghum silage, and corn silage on intake, milk production, milk composition, and nutrient digestibility of lactation dairy cows was evaluated. Twenty-four Prim’Holstein (PO) cows were used, forming three groups of eight cows each. The experimental treatments were: 1) corn silage; 2) grain sorghum silage; and 3) sweet sorghum silage, fed ad libitum, with two commercial concentrates, distributed following the cow milk production. Grain sorghum silage promoted greater DM intake (22.98 kg/day) compared […]

This experiment was carried out to evaluate the influence of the linseed oil addition in replacement of soybean oil in laying hens diets on performance and internal and external egg quality. A total of 192 laying hens Bovans Godline line with 29 week-old, were distributed to six treatments, that consisted of a control diet (without vegetal oil) and of five diets containing 2% of linseed oil in replacement of 0, 25, 50, 75 and 100% of soybean oil, generating levels […]

The objectives of the present work were to determine nitrogen compounds flow into the abomasum, total carbohydrate and organic matter ruminal degradation, microbial efficiency, N-NH3 concentration and ruminal pH in cattle fed with diets based on corn silage, elephant grass silage and Tifton-85 bermudagrass hay. Six ruminal and abomasal fistulated cattle were utilized in a double 3 × 3 latin square. Abomasal digesta dry matter of and microbial dry matter flows were determined by use of indigestible neutral detergent fiber […]

Thirty-five male kids Boer × Saanen kids were shaughtered at 5, 10, 15, 20 e 25 kg BW to evaluate the carcass traits and commercial cuts and tissues allometry. The diet fed to the animas was composed by cow milk in the first 49 days and ad libitum ration from the seventh day until slaughter. The cuts were obtained after cooling of the carcass and the leg dissected in muscle, bone and fat. The body weight showed a negative linear […]
