Haemonchus contortus, the main gastrointestinal nematode parasitizing sheep, has developed resistance to all classes of anthelmintics, making it essential to study alternative control methods that reduce reliance on these drugs. This study aimed to develop a passive immunization protocol by produ...

Objective: This study aimed to estimate genetic parameters and evaluate genetic correlations between temperament and facial hair whorl traits with productive, reproductive, and carcass traits in Canchim beef cattle. Methods: Phenotypic records from animals born between 2013 and 2022 were analyzed...

A qualidade de plantas forrageiras determina o desempenho animal em gramíneas tropicais quando não ocorre limitação de forragem em oferta. Os animais sob pastejo são seletivos, colhendo preferencialmente lâminas foliares, as quais diferem em qualidade entre os genótipos devido ao grupo anatô...

Paspalum notatum Fl. é uma gramínea rizomatosa nativa da América do Sul, sendo um importante componente das pastagens naturais da Argentina, do sul do Brasil e do Paraguai [1]. Diversos biótipos são encontrados no Brasil e vários destes são dominantes na composição botânica de ...

Lipid-coated aging has been proposed as an alternative to enhance flavor, particularly using butter as a coating material (butter-aged beef). Thus, this study compared the wet-aged and beef-aged with different lipid-based coatings: milk butter (butter-aged), cocoa butter (cocoa-aged), pork lard (...

This study evaluated the effects of a bromoform based feed additive (BBFA) on growth performance and enteric methane emissions in Nellore cattle during feedlot backgrounding and finishing phases. Ninety-six Nellore bulls (10 +/- 2 mo old, body weight (BW) 315 +/- 23 kg (b...

Variable resistance to Haemonchus contortus infection and the associated immune mechanisms have been investigated and characterized in different sheep breeds adapted to tropical climates. In a recent study, we compared the local immune responses of the resistant Santa Inês with those of ...
