Abstract

Breeding records, including 649 inseminations during fall and winter at a dairy farm in a subtropical area of Western Mexico (24°N; 24°C, mean annual temperature 24°C) were analyzed to document effects of sex-sorted semen from commercial Gyr bulls, estrus synchronization protocol, inseminator, sire ...

Abstract

Polynomial regression models of the first, second, and third order were used to fit milk production deviations of daughters in Mexico on Canadian and US predicted transmitting ability values for 305-d mature-equivalent milk production (kg). For the pairs Canada-Mexico and Mexico-United States, 40...

Abstract

The main objective of this study was to assess the effect of month of breeding on reproduction performance of Holstein heifers and cows inseminated with sex-sorted or conventional semen in a hot environment. Pregnancy per artificial insemination (P/AI; 64,666 services over an 8-year period) both in ...

Abstract

The aim of this study was to estimate genetic and phenotypic (co)variances for lactation curve traits and for days open in Holstein cows. Data included 1 579 lactations from 766 cows, daughters of 126 sires in a dairy herd in northern Mexico. The studied traits within lactation were days open (DO), ...

Abstract

The objective was to determine the effect of including silages of annual ryegrass (Lolium multiflorum) intercropped with winter vetch (Vicia villosa) (ARG-VV) or with common vetch (Vicia sativa) (ARG-VS) compared with maize silage (MS) on milk yield and milk composition of dairy cows grazing...

Abstract

Records representing data from 1,500 barren Holstein cows over an 8-yr period from a large commercial dairy farm in northern Mexico were analyzed to determine the effects of lactation number and season and year of initiation of lactation on milk production of cows induced hormonally into lactation...

Abstract

The aim of this study was to evaluate the effects of restricted suckling (RS) in Holstein cattle on the weight gain, health and behaviour of calves and on udder health and milk let-down in cows compared to artificial rearing (AR). The study was conducted in Mexico. The 27 cows with calves were...

Abstract

Antimicrobial therapy is a useful tool to control bovine mastitis caused by Staphylococcus aureus, as consequence an increase in staphylococci resistant cases has been registered. Alternative strategies are desirable and bacteriocins represent attractive control agents to prevent bovine mastitis....

Abstract

Data (1970-97) from 47 609 cows and pedigree information from 57 787 Holstein cattle were used to estimate heritabilities, as well as genetic and phenotypic correlations for length of productive life until third lactation (DVP), total milk production until third lactation (PTA), ability to maintain ...
