To evaluate the effect of probiotic (Lactobacillus sp.) associated with different crude protein (CP) levels on performance, CP nutritional requirements, carcass and cut yields of meat quails, a total of 2304 meat quails were distributed in a 2 × 4 factorial design (with and without probiotic and four CP levels – 15, 20, 25 and 30%), with two replications per treatment, repeated twice in time (two experimental periods), totalizing 32 experimental units. The addition of probiotic decreased the feed intake […]

This study was to evaluate the use of fodder salt (salt and dicotyledon hay mix) on daily intake of fodder salt (IFS) and pangola (Digitaria decumbens) hay, and intakes of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), hemicellulose (HCEL), lignin and water (AGU), in addition to daily weight gain (ADG) and feed conversion tatio of lambs in confinement. Fodder salts were compound by dicotyledon hay meal (90%), mineral salt (5%) and ground maize (5%). Thirty non-castrated male […]

In this study, it was evaluated the productive performance of nine Zebu × Holstein crossbred calves in comparison with nine Holsteins calves for veal production. All animals were maintained in the similar environmental conditions, management and feeding, with individual measurement of dry matter intake. The evaluation measurements of the development of animal, as feed conversion ratio make possible to compare between the treatments, using a completely randomized design. The Zebu × Holstein calves showed higher values of hearth girth growth […]

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 […]

This experiment was carried out to evaluate the substitution of corn silage by fresh pressed citrus pulp (FPCP) on the performance of Santa Ines lambs. Twenty-four lambs, with average age of 90 days and initial average body weight of 18.44 kg, were feedlot during 67 days and fed with increasing levels of FPCP in substitution of corn silage (0, 25, 50, and 75 % DM). There was no difference for DM intake (DMI). The average values for DMI in g, […]

The trial aimed to evaluate the effect of particle size (small: from 0.2 to 0.6 cm or large: from 1.0 to 2.0 cm) and cutting height (low cut: 15 cm or high cut: 39 cm) of the corn plant on dry matter intake and performance of steers in a feedlot. The treatments were: T1 – small particle size with low cutting height; T2 – large particle size with low cutting height; T3 – small particle size with high cutting height; […]

The objective of this trial was to evaluate the effect of feed restriction during a grazing period of 104 days (phase I) on intake, feed conversion, and digesta load as well as body weight (BW) change and weights of carcass and non-carcass components during a feedlot period (phase II) in crossbred steers. Thirty nine crossbred Holstein-Gyr steers averaging 19.3±5.1 months of age and 202.0±49.1 kg of BW at the beginning of the study were used. Animals were assigned to one […]

Twenty crossbred male Santa Inês sheep were assigned to a completely randomized block design to evaluate the effects of feeding dried cashew pulp (DCP) on performance, digestibility of nutrients, and nitrogen balance. It was also of particular interest to study the economical viability of adding DCP to diets of feedlot sheep. Diets were isonitrogenous and contained ground Tifton 85 hay (Cynodon spp), corn, soybean meal, salt, and one of the following levels of DCP: 0, 10, 20, 30 or 40%. […]

Intake, digestibility of nutrients, daily weight gain, and feed conversion were evaluated in beef cattle receiving diets containing the following ratios of sorghum silage:Tifton 85 haylage: 0:100; 32:68; 66:34; and 100:0. Diets were formulated to be isonitrogenous (12% crude protein) with a forage:concentrate ratio of 60:40, on DM basis. Twenty-four crossbred Holstein x Zebu steers averaging 360 kg of initial body weight were distributed in a completely randomized block design with 15 days for diet adaptation followed by three experimental […]

The objective of this experiment was to evaluate the performance of crossbred Charolais x Nellore young steers fed diets with different corn hybrid silage: Agroceres AG9090, Dekalb DK440 or Braskalb XL344. Animals were feedlot finished until reaching approximately 430 kg of body weight. The average age of the animals at the beginning and at the end of the trial was 10.3 and 15.2 months, respectively. Diets were formulated to contain a forage:concentrate ratio of 60:40 (DM basis) with the following […]
