Abstract

Background: A concern for breeders is whether an animal ranking based on genetic evaluations is similar to that obtained from show-ring judging. Objective: to determine the association between rankings for Braunvieh (BR) and Brown Swiss (BS) cattle of Mexico based on show-ring judging and their...

Abstract

Crossbreeding effects were evaluated in three dual purpose bovine sub-populations in the tropics, and 5,040 lactations, 4,429 birth weights and adjusted weights at 205 [3,878], 365 [3,017] and 540 [2,276] days (PN, P205, P365 y P540, respectively) from Zebu cattle (CE) and its crosses with Holstein ...

Abstract

The aim of the study was to analyze different factors that affect the productive and reproductive rates of dual purpose cows (DP). 2584 lactations of 840 cows racial groups were analyzed: 1/2 Holstein (Hs) × 1/2 Zebu (C), 1/2 Brown Swiss (Ps) × 1/2 C, 3/4 Hs × 1/4 C, 3/4 Ps × 1/4 C, + Hs × C, + Ps...

Abstract

Records of 1,289 cows at first calving with different proportions of Bos indicus and Bos taurus genes (Charolais, Brown Swiss, Simmental, Holstein Friesian, Salers) were analyzed. The cows were both purebreds and crossbreds from a commercial herd born between 1966 and 2006. They were used to...

Abstract

This study was carried out in the municipality of Villaflores, Chiapas, Mexico, to determine genotypic and allelic frequencies of the leptin gene in exon 2 in dual purpose cattle. The polymorphism was observed by ARMS-PCR. 47 sires in active service in the production system were included in this...

AbstractFull Text

The objective of this work was to estimate the genetic and phenotypic correlations among fertility traits of 317 Holstein Friesian and Brown Swiss cows. Cows were born and reared under subtropical conditions, during a 20-year period (1986 to 2006), and were daughters of 116 sires and 199 dams. The...

Abstract

The objective of this study was to evaluate the effect of environmental factors and to determine the optimum proportion of Bos taurus (BT) genes on milk yield (MY) and reproductive traits of % Holstein-Friesian (H) × 1/4 zebu (Z), 3H1Z; 3/4 Swiss (S) × 1/4 Z, 3S1Z; 1/2 H × 1/2 Z, HZ and 1/2 S × 1/2 ...

Abstract

1746 calving records of Tropical Dairy Criollo (TDC) cows and their crosses were collected between 1972 and 1990 at the experiment station of the Mexican Association of Animal Production on the Gulf Coast of Mexico. Traits studied were 305-day milk yield, days in lactation, number of services per...
