Genotype by environment interaction for post-weaning weight gain, scrotal circumference, and muscling score of composite beef cattle in different regions of Brazil
(Funpec-editora, 2014-01-01)
The objectives of this study were to characterize and define homogenous production environments of composite beef cattle in Brazil in terms of climatic and geographic variables by using multivariate exploratory techniques; ...
Genetic study of skin thickness and its association with postweaning growth in Nellore cattle: estimation of the genetic parameters
(Funpec-editora, 2016-01-01)
The objective of the present study was to estimate genetic parameters for skin thickness (ST) and postweaning weight gain (PWG550) in Nellore cattle. Records were obtained from 152,392 Nellore animals born between 2001 and ...
A meta-analytical study about the relation of blood plasma addition in diets for piglets in the post-weaning and productive performance variables
(2013-08-01)
The meta-analysis was used to evaluate the performance of piglets in post-weaning period, without imposition of sanitary challenge and fed diets containing blood plasma, obtained by spray-dried process (SDBP). Piglets are ...

Genetic parameters for postweaning traits in Braunvieh cattle
(FUNPEC-EDITORA, 2010)
Genetic parameters for traits related to postweaning growth in Braunvieh cattle, reared under tropical and sub-tropical conditions in Brazil, were studied. Weight traits were weight at 365 days of age (W365, N = 4055), at ...
Anthelmintic treatment and supplementation in Nellore calves performance in the post-weaning period
(2017-05-01)
The objective of this study was to analyze the effects of anthelmintic treatment and supplementation of post-weaning Nellore calves. The parasitism degree, hematological changes and animal performance were analyzed, as ...
