Abstract

Due to the increasing importance of cryptosporidiosis in animal productivity, this study was carried out to investigate the occurrence of Cryptosporidium spp. and its association with animal weight development and fecal consistency in crossbred Nellore cattle. Thus, fecal samples of 30 cattle were...

Abstract

The present study aimed to evaluate the reproductive efficiency and establish the incidence of reproductive diseases in Nelore (pure breed) animals via rectal palpation in cows and a retrospective survey, through property records, obtaining days open (DO) and calving interval (CI). The DO and CI...

AbstractFull Text

The objective of this study was to characterize the displacement patterns of Nellore cattle in areas of crop livestock and crop livestock forest integration systems with density of 196 and 448 eucalyptus ha-1. Paddock maps were drawn from satellite images of the experimental area. In each evaluated ...

AbstractFull Text

Protein-energy supplementation (SPE) is an adequate strategy for beef cattle during drought season of the year, although the wrong adoption might compromise its cost/benefit ratio. The aim of this study was to evaluate Nellore heifers' performance under SPE periods and to draw economic analysis of...

Abstract

Early weaning (EW) has been adopted in cattle breeding farms in Pantanal as a strategy to increase the rate of pregnancy in cows. The primary income of these properties is the production of beef calves, and the price of these animals depends on their weight. Therefore, the calves subjected to EW...

Abstract

The objective of this study was to investigate the population genetic structure and the effects of inbreeding on growth traits of Nellore breed animals from the Amazon biome. The database used for the analyzes contained records of 1,402,287 animals born between the years of 1950 and 2012 and weight ...

Abstract

The objective of the present study was to identify genetic variation in heifer pregnancy due to heat stress in Nelore cattle during the breeding season. The Nelore heifers were born between 2003 and 2013 on six farms located in three Brazilian States. Heifer pregnancy (HP) was analyzed as a binary...
