The objective of this study was evaluate the yields and weights of the organs, viscera, by-products and edible offal in 32 males castrate Morada Nova hair sheep breed, in feedlot, fed with diets containing 20.0 40.0 60.0 and 80.0 % of concentrate. The animals (8.11 ± 1.15 months old, 19.67 ± 2.97 kg BW) were slaughtered at 30.0 kg BW. A completely randomized blocks design, with four diets and eight replicates, was used. The crescent concentrate levels increased empty body […]

The objective was to study the effects of partial replacing of corn silage by corn gluten feed (CGF-21) dehydrated on milk production and composition of milk and in the blood parameters of dairy cows, beyond the economic evaluation. Inclusion levels of 0, 8 and 16% of CGF-21 (% DM) to the diets were evaluated. Thirty cows were used for study of milk production and composition and fifteen cows for blood parameters study. A 3 x 3 Latin Square experimental design […]

The objectives of this trial were to evaluate the effect of replacing corn meal with coffee hulls or soyhulls on intake and apparent digestibility of nutrients, milk yield and composition, and body weight (BW) change in lactating dairy cows. Twelve purebred and crossbred Holstein cows were assigned to three replicated 4 ´ 4 Latin squares. Diets were isonitrogeneous (14% of CP, DM basis) and control diet contained 60% corn silage plus 40%concentrate. Three sugarcane based diets with 60% concentrate were […]

The objective of this trial was to evaluate the apparent total tract digestibility of nutrients on sheep fed diets containing ammoniated elephantgrass silage plus cocoa meal or palm kernel cake, which partially replaced corn and soybean meal in the concentrate. Eighteen non-castrated Santa Inês sheep averaging 22.6 kg of body weight were assigned to a completely randomized design with a 2 x 3 factorial arrangement of treatments. The experiment lasted 77 days with 14 days for diet adaptation and three […]

Milk fat from 12 7/8 crossbred Holstein-Zebu lactating dairy cows was used to evaluate the effect of different diets on milk fatty acid (FA) profile and milk CLA content. Cows were fed concentrate containing corn (CR), wheat bran (WB), or dried citrus pulp (CP) supplemented or not with soybean oil. Chromatographic analysis showed a FA recovery greater than 95%. With the exception of milk content of trans-10 C18:1 and proportions of trans-10 C18:1 and trans-11 C18:1 on total milk trans– […]

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 […]

The effects of replacing corn and soybean meal with cocoa meal (CF) or palm kernel cake (PKC) in the concentrate on milk intake and yield of goats were evaluated. Five Saanen goats, averaging 2 kg daily milk yield at 60 days of lactation, were assigned to a 5 x 5 Latin square experimental design. The experiment lasted 14 days, with 10 days for adaptation period and four days for sample collection. Diets contained: 36% of roughage (corns silage) and 64% […]

An experiment was conducted to evaluate the use of animal by-products in diets of broilers from 22 to 42 days of age, formulated based on crude and ideal protein concepts. The experimental design was a completely randomized in a factorial arrangement 2×2+1 with two animal protein sources (poultry viscera meal and bovine blood meal), two formulation concepts (based on crude and ideal protein) and a control diet based on corn and soybean meal, with four replications. The evaluated characteristics were […]

The objective of this research was to evaluate total rations with differents levels of swine waste on the productive performance of sheep, in a feedlot system during 56 days, where seven days of adaptation and 49 days for data collect. Were utilized 32 Santa Inês hair sheep, aged seven months aproximately and with average body weight of 25.2±3.9 kg, distributed in four blocks as for body weight. A randomized complete block design, with four treatments (Swine waste levels: T1=0%, T2=4.2%, […]

The objectives of this work were to evaluate effects of replacing corn by cassava by-product meal, in diets of Saanen lactating goats, on milk production and composition (total solids and crude protein), nutrient apparent digestibility and total digestible nutrients (TDN) of diets. Four multiparous goats fitted with ruminal cannula, with 100 days of lactation, were used. The design was a 4 x 4 Latin square and treatments as following: 0, 33, 67 and 100% replacement of corn by cassava by-product […]
