The present study aimed to evaluate the application of shear strength and its correlations with leaf blade morphological and chemical variables as a tool capable of detecting differences between species and accessions of the genus Paspalum in the early stages of a forage plant breeding programme. A total of 13 Paspalum accessions from two species (Paspalum atratum and Paspalum regnellii) were subjected to analy...
This study characterizes the changes in leaf mass, morphological composition and nutritional value of leaf blades of palisadegrass (Urochloa brizantha cv. Marandu) under continuous grazing in the first year of implementation of pasture and after second year of the eucalyptus planting in an Integrated Crop-Livestock System and Integrated Crop-Livestock-Forest, which were tested in the four seasons. The experimen...
The objective of this study was to evaluate the effects of combinations of dry and moist corn and sorghum grain on the carcass and cut characteristics of crossbred lambs Suffolk x Santa Inês produced in feedlots. The experimental design was a randomized block with four treatments and three replicates. Sixty uncastrated male lambs with an initial average weight of 15.5 kg were used in this experiment. Four combi...
The economic losses caused by gastrointestinal nematodes are one of the biggest obstacles in the small ruminants production. Understanding the population dynamics of the infective larvae (L3) in the pasture is the key point to develop control programs, and reliable results depend on the used methodology to quantify L3 numbers. The use of the sampling directly from the pasture appears as a viable option, since i...

Foram utilizados 15 cavalos da r...
Indigestible fractions of dry matter (iDM) and neutral detergent fiber (iNDF) in the feed of ruminants are mainly estimated by in situ incubation time with regard to particle size and textile types. Samples of alfafa, ground into three particle sizes, were analyzed. Samples, processed in a Willey mill with 1.0; 2.0 and 3.0 mm sieve pores, were conditioned in F57 (Ankon®), nonwoven (100 g m-2) and polyester text...
Water deficiency during the dry seasons influences the relationship between water and gas exchange in tropical grasses, reducing their productive potential. In addition, the phosphorus (P) deficiency Brazilian soils adds to the set of factors limiting crop production. In this context, the objective of this study was to evaluate the responses of different tropical forage species to phosphorus supplementation as ...
O objetivo do presente estudo foi avaliar a degradabilidade ruminal da matéria seca (MS), proteína bruta (PB), fibra em detergente neutro (FDN) e amido e a digestibilidade in vitro da matéria seca (DIVMS) da silagem de híbridos de milho em função de duas texturas, três estádios de colheita, três tamanhos de partículas e processamento por meio do esmagamento. Após colheita e picagem, parte do material foi esmaga...
Este estudo foi conduzido na Fazenda Canchim em São Carlos-SP, área física da Embrapa Pecuária Sudeste, objetivando selecionar, com base nas características agronômicas de produtividade de matéria seca e qualidade da forragem, os acessos das espécies do gênero Paspalum indicados por possuir potencialidade para utilização como plantas forrageiras. Foram avaliadas durante 3 anos, 22 gramíneas forrageiras, sendo 1...
O milho é a cultura mais utilizada para confecção de silagem. A eficiência do processo deve ser avaliada também pelos custos por kg de massa seca colhida (KgMS). O objetivo deste trabalho foi avaliar o consumo de energia na colheita de híbridos de milho para ensilagem em função da textura do híbrido, quatro maturidades de colheita e três tamanhos de partículas - Tp Foi utilizado um trator da marca Massey Fergus...
