Carcass yield and growth of organs and innards of 40 crossbreed F1 Holstein X Gir calves fed different liquid diets (whole milk or fermented colostrum-based diets), supplemented or not with soy oil (45 mL) and with or without growth promoter Zeranol were evaluated. The animals were daily fed a diet with concentrate (23% crude protein), Tifton hay ad libitum and 3 L of milk or fermented colostrum. The animals were slaughtered at average weight of 57.38 kg and 60 days […]

The objective of this trial was to evaluate ruminal, intestinal, and total tract apparent digestibilities of nutrients as well as metabolism of ruminal and nitrogenous compounds in supplemented finishing cattle during the drought to rainy transition season. Five Holstein x Zebu steers averaging 304 kg of live weight and 24 months of age located in five paddocks (0.34 ha each) of Brachiaria decumbens were used in this trial. The supplements fed (4 kg/animal/day) contained ground corn, whole soybean, urea, ammonium […]

The root system (pre and post grazing) characteristics of aruanagrass and tanzaniagrass under two nitrogen rates (150 and 300 kg ha-1 N year) grazed by sheep in variable rotational stocking (three to seven grazing days) and variable rest period were evaluated in this study. The treatments were assigned to a complete randomized block (two) design with two replicates (plots = grasses and split-plots = nitrogen rates)within repeated measures. In the pre-grazing tanzaniagrass, averages within nitrogen rates and grazing period showed […]

The objective of this experiment was to study the effects of feeding whole goat milk or fermented cow colostrum supplemented or not with soy oil and with or without the growth promoter Zeranol on performance of kid goats. Twenty-four Alpine kid goats assigned to a completely randomized design in a 3 x 2 factorial arrangement were used in this trial. The following variables were investigated: weight gain, intakes of dry matter and concentrate, feed conversion, and organ sizes. Significant differences […]

The objective of this trial was to evaluate the voluntary intake and ruminal passage of particles in supplemented finishing cattle during the drought to rainy transition season. Five Holstein x Zebu steers averaging 304 kg of live weight and 24 months of age located in five paddocks (0.34 ha each) of Brachiaria decumbens were used in this trial. The supplements fed (4 kg/animal/day) contained ground corn, whole soybean, urea, ammonium sulfate, and minerals and were formulated to yield, on as-fed […]

The objective of this trial was to study the effects of replacing milk with whole milk or fermented colostrum, supplemented or not with soy oil and with or without growth promoter (Zeranol) on performance of 40 F1 Holstein x Gir calves averaging 36 kg. Weight gain, thoracic circumference, withers height and milk or fermented colostrums intake, and concentrated ration intake were the variables investigated from age 15 to 60 days. No significant difference on feed intake was observed when whole […]

A mixture of two winter forages: black oat (Avena strigosa Schreb. cv. Common) and Italian ryegrass (Lolium multiflorum Lam. cv. Common) was introduced in a pasture of aruanagrass (Panicum maximum Jacq. cv. Aruana), grazed by sheep in an intensive production system (irrigation, fertilization and rotational stocking) with the objective of increasing the forage nutritive value during the dry winter period. From 04-14-00 to 01-18-01 and 06-07-01 to 02-22-02, the chemical composition and digestibility of pre-grazing forage were evaluated in six […]

Five lactating Brown-Swiss cows averaging 520 kg of body weight (BW) and 15 kg of milk yield were assigned to a 5 x 5 Latin square to study the effects of replacing sorghum silage (Sorghum bicolor L. Moench) with a columnar cactus known as xiquexique (Pilosocereus gounellei (A. Weber ex K. Schum.) Byl ex Rowl.) on animal performance and apparent digestibility of nutrients. The experimental diets contained (DM basis): 0, 12.5, 25, 37.5, or 50% of xiquexique. Each experimental period […]

Body weight gain of 103 Nelore calves until 20/21 months old when weaned on cultivated pasture and supplemented during the dry period was evaluated during three years to obtain steers with body weight to be finished immediately at fedlot. At the beginning and end of supplementation period, the animals averaged body weight and age of 189.51± 21.08 kg and 254 ± 29.22 days and 242.38 ± 29.22 kg and 400 ± 31.08 days, respectively. The mean daily feed intake was […]

The experiment was carried out to establish the lysine requirement of females swine, from 6 to 16 kg live weight. Sixty crossbreed gilts with high genetic potential for lean gain and average initial and final weight of 6.0 ± 0.21 kg and 16.0 ± 0.32 kg, respectively, were assigned to a randomized blocks design, with five treatments, four replications and three animals per experimental unit. The treatments corresponded to a basal diet with 21.60% crude protein, supplemented with five levels […]
