This work was carried out with the objective to evaluate the effect of replacement of soybean meal by common bean (Phaseolus vulgaris L.) residue in rations for milking cows on the following variables: intakes and total apparent digestibilities of nutrients, milk production and composition and feeding efficiency. Twelve Holstein cows were randomly assigned to three 4 ´ 4 balanced latin square design. The animals was fed ad libitum total mixed rations, which contained 0; 13; 26 and 39% of raw […]

The objective of this study was to evaluate the effects of diets with different levels of fresh orange pulp in substitution to sorghum silage on eating behavior (feeding, rumination and idle)in sheep. Sixteen wethers, crossbred breeds averaging 28.27 kg BW (±2.41) were allotted to a randomized blocks design, with four treatments (0, 25, 50, and 75%), two blocks and two replicates per block. Animals were evaluated by observation during two consecutive days. In the first day, the average number of […]

An experiment was carried out with the objective of evaluating the effect of different lysine levels in diets supplemented or not with ractopamine (RAC) on the performance and carcass characteristics of finishing barrows. Forty commercial hybrid swines were distributed to a randomized experimental block design, in a 2 x 2 factorial arrangement, with two digestible lysine levels (0.67 and 0.87%), with adjustment for the others amino acids to achieve an ideal protein relationship, and two levels of RAC (0 and […]

The influence of feeding frequency was evaluated on weight gain, specific growth rate, feed conversion and survival of jundiá juveniles. Twelve groups of 280 fish (7.47 ± 1.73 g) were each stocked in twelve ponds (2 fish/m2) and fed to apparent satiety an extruded commercial feed containing 42% CP In four feeding schedules: 1, 2, 3 and 4 times a day, in triplicate, for 120 days (May to September, 2003). Average weight gain was recorded by sampling 10% of the […]

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 […]

An assay was conducted to evaluate the development of Iguaçu surubim (Steindachneridion melanodermatum) larvae fed different diets. The experiment was analyzed as a complete randomized design with five treatments and four replicates, in 35 L-aquaria, each one with 15 larvae (8.35±0.85 mm and 6.75±0.64 mg). The treatments consisted of five feeding programs: Artemia (A); diet (D); zooplankton (Z); Artemia with diet (A+D); and zooplankton with diet (Z+D). Larvae development was evaluated in illuminated environment during 29 days. For larvae feeding […]

The effects of feeding elephantgrass silage ammoniated or not with urea (5% DM basis) and the concentrate replacement (corn and soybean meal) by cocoa meal (CM) or palm cake (PC) on the ingestive behaviour of 18 Santa Inês non-castrated male sheep averaging 22.62 kg of initial body weight were studied. The animals were allotted to individual pensas a completely randomized design with six treatments, two roughages (elephantgrass silage ammoniated with urea or not) and three concentrate replacement level with by […]

Twenty crossbred bulls (1/2 and 3/4 Bos taurus x Bos indicus) averaging 24 months of age and 532 kg of body weight at the beginning of the experiment were used. Animals were randomly assigned to five treatments (four replicates/treatment) in a completely randomized design to evaluate the effect of replacing corn grain with a wet byproduct of cassava starch extraction on apparent digestibility of nutrients. Bulls were fed diets containing sorghum silage and one of the following levels of cassava […]

The objective of this study was to evaluate the effect of replacing coastcross (Cynodon dactylon) hay with a dehydrated pineapple by-product (DPB) on performance, apparent digestibility, and intake of digestible nutrients in growing goats. Twenty-four crossbred Saanen x Criola female goats averaging 19.2 kg of body weight (BW) at the beginning of the trial were used in a completely randomized design. Animals were assigned to one of the following four treatments: 0, 33, 66, or 100% of DPB in the […]

Fifty Alpine lactating does were used to evaluate the effects of feeding different levels of forage neutral detergent fiber (FNDF) on nutrient intake and milk yield and composition. Animals were housed individually and assigned to a completely randomized design with five treatments and ten replicates. A total mixed ration, containing Tifton-85 (Cynodon sp.) hay, ground corn, soybean meal and mineral mixture was fed ad libitum. The experimental diets contained 20, 27, 34, 41 or 48% of FNDF. As dietary FNDF […]
