Abstract

The aim was to carry out a survey of dairy farms concerning aspects related to the pre-weaning and post-weaning of dairy cows. Interviews were conducted with 30 dairy farmers of different technological levels and milk production scale in the period of April to July of 2016. A semi-structured form...

The objective of this work was to study "days for a specific weight" traits in Nelore breeding programs comparing them with traditional traits such as average daily weight gain. Thus, this study aimed to estimate genetic parameters for days to reach 180 kg (D180), days to reach 300 kg (D300),...

Abstract

Providing a solid diet in addition to sow milk during lactation (creep feed) is a management commonly recommended to producers. This practice was introduced as a strategy to minimize the deleterious effects of abrupt and early weaning, as well as to standardize the litters to be weaned, to increase ...

AbstractFull Text

The aims of this study were to estimate genetics parameters for average daily gain from birth to weaning (DGBW) and post weaning average daily weight gain (PDWG) of animals of the Nellore breed, born from 1978 to 2007. Data was provided by File zootechni cal covenant ABCZ/EMBRAPA/MAPA. The dataset...

Abstract

The aim of this study was to evaluate the effects of gender, type of birth, doe weight at delivery and gestation period on the weight of crossbred Boer kids at birth, 30, 60 and 90 days of age. Daily weight gain from birth to 60 days of age and from 60 to 90 days of age was also followed. In the...
