1. Grazing height targets for Alexandergrass pastures under continuous stocking in integrated crop-livestock system
RESUMO: O objetivo deste trabalho foi identificar alturas de manejo para pastos de papuã sob lotação contínua em sistemas de integração lavoura-pecuária (ILP). Para tanto, doze pastos foram cultivados em uma área de ILP e mantidos em 10, 20, 30 ou 40 cm por meio de lotação contínua com caprinos. As seguintes variáveis foram analisadas: massa; ta

2. Beef cattle performance on signal grass pastures deferred and fertilized with nitrogen
RESUMO Foi avaliado o efeito de quatro doses de nitrogênio (0, 40, 80 e 120kg N ha -1 ), aplicadas antes do diferimento, sobre o desempenho de bovinos e as características estruturais de Urochloa decumbens (capim-braquiária), de janeiro a outubro de 2012 e de janeiro a setembro de 2013. Um delineamento de blocos ao acaso foi utilizado em arranjo de medid

4. Can the strategies for endoparasite control affect the productivity of lamb production systems on pastures?
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 u

5. Influence of lamb finishing system on animal performance and meat quality
ABSTRACT. This study aimed to assess the influence of lamb finishing systems on zootechnical performance, as well as on carcass and meat quality. The experiment was conducted at the APTA’s experimental farm. Thirty-three lambs were used - both sexes, initial age of 90 ± 3 days, Texel with Santa Inês, each animal being one experimental unit, with 6 males

6. Binary programming for the simulation of crop rotation and animal transit in an integrated crop-livestock system
RESUMO O objetivo é desenvolver e implementar um modelo de programação linear (PL) que forneça como resultado um cronograma com a melhor seleção de cultivos em cada gleba por período e com o maior ganho de peso de cada animal. O modelo de programação linear foi desenvolvido a partir do trabalho empírico realizado por Alvarenga e Gontijo Neto (2008)

7. Beef cattle performance in response to Ipyporã and Marandu brachiariagrass cultivars under rotational stocking management
ABSTRACT The objective of this two-year study was to evaluate live weight gain per animal and per area and their relationships with the characteristics of BRS Ipyporã (Brachiaria ruziziensis × Brachiaria brizantha) and Marandu (Brachiaria brizantha) pastures. A completely randomized block design was used with two treatments and four replicates. The grazing

8. Dry matter intake, performance and carcass characteristics of hair sheep reared under different grazing systems
ABSTRACT The aim of this study was to evaluate the effect of three different grazing systems: isolated, alternate and simultaneous, on feed intake, performance and carcass characteristics of sheep. About 5.2 ha area of Tanzania grass (Panicum maximun Jacq cultivate Tanzania) was divided into 13 paddocks. This area was used as a stocking rate of two animal un

9. Phenotypic association between feed efficiency and feeding behavior, growth and carcass traits in Senepol cattle
ABSTRACT The objective of this study was to evaluate the associations between feed efficiency and feeding behavior, growth and carcass traits in Senepol cattle. A total of 137 animals were evaluated. Of these animals, 36 males were evaluated in a second test, totaling 173 records (initial age of 466±96 days and initial weight of 426±104 kg). Residual feed

10. Animal performance and sward characteristics of two cultivars of Brachiaria brizantha (BRS Paiaguás and BRS Piatã)
ABSTRACT The objective of the present study was to evaluate live weight gain per animal and per area and its relationship with the characteristics of pastures of Brachiaria brizantha cv. Paiaguás and Piatã. A randomized blocks experimental design was used, with two treatments and six replicates. The experimental area was 8.0 ha, divided into twelve paddock

11. Sward structure and livestock performance in guinea grass cv: Tanzania pastures managed by rotational stocking strategies
Grazing strategy is a key element in the determination of sward structure, herbage nutritive value and animal performance. We aimed to compare the herbage characteristics and performance of livestock in pastures of Panicum maximum cv. Tanzania managed, using two rotational stocking strategies, which provided either a fixed-length rest period (FRP) of 35 days

12. ESTUDO DA RECRIA DE NOVILHAS DE CORTE EM PASTAGENS CULTIVADAS DE VERÃO / STUDY OF BEEF HEIFERS REARING ON WARM-SEASON PASTURES
Heifers rearing is a determinant step of efficiency in beef cattle production systems on pastures. Several experiments have tested alternative uses for tropical grasses to heifers rearing. In order to summarize results and making not visible relationships evident in these individual experiments an analysis was performed in a set of data from six experiments
