2. Overprice on purchase of replacement cattle and genetic group as variables of economic result in feedlot operations
ABSTRACT The objective of this study was to analyze the economic result of feedlot operation for three genetic groups of cattle (Nellore, Nellore crossing with other Zebuine breeds, and Dairy crossbred) as a function of the overprice on the purchase price of cattle to be feedlot-finished. The study involved data of 57,589 animals divided into 709 lots origin

3. Multivariate analysis of productive and nutritional traits and feeding behavior of sheep fed roughage-free diets
ABSTRACT The objective of this study was to evaluate productive traits in sheep fed roughage-free diets by multivariate analysis. Forty lambs were used in this study: 20 Santa Inês animals, consisting of 10 uncastrated males and 10 females; and 20 crossbreds (½ Santa Inês × Dorper), consisting of 10 uncastrated males and 10 females, at an average age of

4. Nutritional requirements of energy, protein and macrominerals for maintenance and weight gain of young crossbred Nellore × Holstein bulls on pasture
The objective of this study was to estimate requirements of energy, protein and macrominerals of young Nellore/Holstein crossbreds bulls supplemented on pastures of Brachiaria decumbens Stapf. Thirty-five young bulls, at 8.53±0.18 months of age and with initial body weight of 230.6±6.1 kg were used. Ten animals were slaughtered as reference, in different w

5. Net requirements of energy, protein and macrominerals for weight gain of grazing beef cattle castrated at different ages, with and without supplementation
The objective of this experiment was to estimate the requirements of energy, protein and macrominerals of grazing crossbreds calves, in Brachiaria decumbens Stapf pasture, castrated at different ages, with and without supplementation. Forty-seven young calves at initial age of 120±30.1 days and 115.3±1.97 kg of live weight were used. To estimate net energy

6. Impacto em características qualitativas de carne bovina in natura decorrente do manejo nutricional e de tecnologias pós-abate, e sua relação com grupo genético / Impact on quality characteristics of fresh beef due to nutritional management and post-harvest technologies, and their relationship to genetic group
Um dos maiores desafios do setor produtivo de carne bovina está relacionado com a inconsistência na maciez. Várias estratégias de manejo nutricional e tecnologias pós-abate foram desenvolvidas com o intuito de diminuir a inconsistência na maciez. O objetivo deste trabalho foi avaliar a interferência dos sistemas de produção e das diferentes estraté

7. Morphological measurements and body indices for Cuban Creole goats and their crossbreds
In this work, linear body measures were taken and production indices calculated for 100 Cuban Creole goats and 100 crossbred goats in order to aid in the characterization of animal genetic resources in Cuba. Low variation was found for all indices of the Creole goats, showing homogeneity between the groups of animals studied. Most of the functional indices a

8. Desempenho produtivo e qualidade da carne de ovinos terminados em pastagem irrigada no semiÃrido nordestino / Productive performance and meat quality of sheep finished in irrigated pasture in the northeastern semi arid
The aim of this study was to evaluate the productive performance and meat quality of animals of Santa InÃs (SI), Somalis Brasileira (SO) and Morada Nova (MN) breeds and  Dorper x  Morada Nova crossbreds (F1) finished in irrigated cultivated pasture. Breeding season was done simultaneously for SI, SO and MN breeds and half of the Morada Nova females was

9. Desempenho de bovinos superprecoces não castrados ou castrados em diferentes idades criados no sistema pasto/suplemento / Performance of young beef cattle uncastraded or castraded in grazing reared in pasture system/supplement
This work was developed in two chapters. The objective of the study described in the first chapter was to evaluate the performance nutritional and carcass traits of grazing young bulls castrate at different ages or not, supplemented or not. Fourty seven crossbred Nellore young bulls with initial age of 120 30,1 were used, housed in paddocks of Brachiaria dec

11. AVALIAÇÃO DE DIFERENTES SISTEMAS DE ALIMENTAÇÃO SOBRE AS CARACTERÍSTICAS QUE AFETAM A QUALIDADE DA CARCAÇA E DA CARNE / EVALUATION OF DIFFERENT FEEDING SYSTEM ON THE CHARACTERISTICS THAT AFFECT THE CARCASS AND MEAT QUALITY
This work was divided in two experiments. In first the objective was to evaluate the carcass, meat, carcass no integrants components and fatty acids profile of intramuscular fat of Devon steers finished in: feedlot (CONF), or winter pasture (pasture of ryegrass - Lolium multiflorum Lam -PTEM), or tropical pasture (association of millet pasture - Pennisetum a

12. Factor XI deficiency in Indian Bos taurus, Bos indicus, Bos taurus x Bos indicus crossbreds and Bubalus bubalis
We investigated the occurrence of Factor XI (FXI) deficiency syndrome in the following Indian dairy animals: Bos taurus Holstein-Friesian and Jersey cattle, Bos indicus Indian cattle breeds, B. taurus x B. indicus crossbreds and the river buffalo Bubalus bubalis. Factor XI deficiency is an autosomal recessive bleeding disorder known to affect Holstein cattle
