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...
