ABSTRACT The objective of this study was to evaluate the productivity and carcass traits of unweaned Suffolk lambs finished on pasture and subjected to three strategies for endoparasite control: prophylactic treatment of all animals every 28 days; treatment of animals with a cut off number of nematode fecal egg count (FEC) ≥ 700; and treatment of animals using the FAMACHA scores ≥ 3. Average daily weight gain (ADG) and FEC were evaluated every 14 days for 112 days. Body condition […]

The objective of this study was to evaluate the characteristics of carcass and non-carcass components in Brazilian semi-arid native goats of different genotypes in feedlot system. It was used 30 non-castrated Azul, Graúna and Moxotó goats with average initial weight of 15.93 ± 2.4, distributed in a completely randomized design with 3 genotypes and 10 replicates. The experimental diet used had a roughage:concentrate ratio of 47:53. There was a significant effect for weight gain and subcutaneous fat thickness according to […]

With the objective of estimating genetic parameters of performance and carcass characteristics of commercially reared ostriches in Ourinhos, SP, it was used the Bayesian method, by using Gibbs sampling algorithm, available in the program MTGSAM (Multiple Trait Gibbs Sampling in Animal Models). It was estimated the heritabilities and genetic correlations for: birth live weight (BW), corrected live weight at 190 days (W190) and at 360 days (W360) of age; pre-slaughter live weight (PSW), weight loss during transport and fasting (WLT), […]

The objective of this study was to evaluate the biometric and morphometric measures, regional composition, carcass characteristics and non-carcass components of Santa Inês lambs submitted to levels of corn replaced by cactus pear in the diet. It was used 45 Santa Ines non-castrated male lambs, with average initial live weight of 25.50 ± 0.48 kg as a completely randomized block design with five treatments (0; 25; 50; 70 and 100%) and nine replicates. There was an effect of the diet […]

This work was aimed at evaluating the effects of green propolis, brown propolis and sodic monensin aditives on the carcass characteristics by means of ultrasound and after-slaughter measures such as carcass non-components and yield of retail products from lambs finished in feedlot system. Thirty-two male lambs, with eight animal per treatment, were feedlot during 64 days. The animals were fed a diet with roughage:concentrate ratio of 50:50, composed of Tifton 85 hay grass (Cynodon spp.) and commercial concentrate. The experimental […]

This work was carried out with the objective to evaluate the effects of different levels (0.0 20.0, 30.0 and 40.0%) of whole cottonseed (Gossypium hirsutum L.) of the diet (% DM) on carcass characteristics, cut yields and carcass muscularity of feedlot Santa Inez sheep. Twenty-four sheep with average initial and final body weight of 19.0 and 32,2kg, respectively, and allotted to a completely randomized design, with four diets and six replications. No effect was observed for the inclusion of whole […]

The characteristics of carcasses and non carcass components of calves fed after weaning until slaughter with high moisture grains silage or dry ground grains of corn or sorghum was evaluated, for production of pink meat veal. Thirty Holstein calves were allotted to a complete randomized blocks experimental design with five blocks and six concentrate rations with similar contents of protein (18.5% CP) and energy (3.2 Mcal ME/kg DM), formulated with dry ground corn (GC), high moisture corn silage (HMCS), dry […]

The objective of this trial was to evaluate weight gain and carcass traits of feedlot Nellore fed diets containing sugarcane bagasse and one of the following concentrate sources: corn germ meal, soybean hulls or citrus pulp that partially (50% DM) replaced ground corn in the diet. The four experimental diets were formulated to yield a forage:concentrate ratio of 39:61. Forty Nellore animals averaging 340 kg of body weight and 32 months of age at the beginning of the trial were […]

The objective of this trial was to study the partial replacement of ground corn with soybean hulls or corn germ meal in diets containing sunflower meal and urea as nitrogen sources and corn silage as forage for confined Nellore steers. Twenty-one steers averaging 25 months of age and 343 kg of initial body weight were assigned to diets containing a forage:concentrate ratio of 60:40. The period for measurements of intake and weight gain lasted 97 days. No significant differences were […]

The objective of this trial was to evaluate the animal performance, carcass characteristics and meat tenderness of 36 crossbred steers averaging 14 months old and 320 kg body weight. The animals were fed high concentrate-based diets: control – without additional fat (CO); diet with 5% calcium salt of fatty acids (AG); and diet with 21% whole cottonseed (CA). Dry matter intake of AG treatment was lower (P=0,05) than CA, that differ from CO diet. No significant differences of treatments on […]
