Genetic parameters of a biological lactation model: early lactation and secretion rate traits of dairy heifers.
Early lactation parameters are difficult to estimate from commercial dairy records due to the small number of records available before the peak of production. A biological model of lactation was used with weekly milk records from a single Holstein herd to estimate these early lactation parameters and the secretion rate of milk from the average cell throughout lactation. A genetic analysis of th...
متن کاملEstimation of Genetic Parameters for Lactation Curve Traits in Holstein Dairy Cows in Iran
The objectives were to estimate (co)variance components and genetic parameters for lactation curve traits in Holstein dairy cows in Iran. The used data were records on Holstein cows collected during January 2003 to December 2012 by the Animal Breeding Center of Iran (Karaj, Iran). In order to describe the lactation curve, an incomplete gamma function was fitted to 691200 test-day records on 962...
متن کاملGenetic and Phenotypic Parameters for Milk Production Traits in the First and Second Lactation in Romanian Simmental Dairy Cows
The aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of Romanian Simmental dairy cattle. For the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...
متن کاملRelationship between season, lactation number and incidence of clinical mastitis in different stages of lactation in a Holstein dairy farm
The aim of the present study was to compare the occurrence and duration of clinical mastitis in different seasons, stages of lactation period and parities in a Holstein dairy farm in Iran. A retrospective epidemiological survey from April 2005 to March 2008 was conducted on 884 clinical mastitis cases of 7437 lactations. Data of each case including calendar-date of mastitis onset, days in milk ...
متن کاملEffect of Restricted Grazing in Early Lactation on Milk Production from Dairy Heifers
Dairy heifers had an estimated grazed pasture intake of either 11.8 (H) or 6.0 (L) kg DM/heifer/day for four weeks in early lactation and a common pasture allowance thereafter. Group L produced less milk (2202 vs. 2433 R) and milk protein (75.0 vs. 81.6 kg) than Group H in 31 weeks but milk fat yield (104.9 vs. 109.8 kg) and milk composition were not significantly affected. All heifers lost bod...
