AbstractFull Text

Oaxaca is the most biodiverse state in México, represented by its wild species and domestic creole livestock. Two creole cattle populations from two regions of Oaxaca were analyzed (Zimatlan: n=26, Ecatepec: n=34) in order to assess their genetic diversity level and to clarify if they are two...

Abstract

In México, there are no studies whose purpose has been characterizing the production units with registered cattle herds. These studies are important because they allow designing successful genetic improvement programs and the transfer of their results to commercial producers. The objective of this...

Abstract

Crossbred dairy cows differ in productive and reproductive traits compared to purebred Holsteins. The objectives of this study were to breed Holstein, Jersey, Montbeliarde and Swedish Red using a breed rotational crossbreeding system and evaluate some productive and reproductive performance....

Abstract

The objective of this study was to characterize and compare predicted transmitted abilities of Brown Swiss and Jersey cattle used in Mexico (MX), and those obtained in the United States (US) and Canada (CA). The database used in this study came from imported American and Canadian Brown Swiss and...

Abstract

The study was conducted to evaluate the heat tolerance, physiological constants, of 32 dairy cows (Chinampo, n=12; Holstein, n=10 and Jersey, n=10) in an arid region of northwest Mexico. Rectal temperature and respiratory rate were recorded every Monday at 06:00 and 17:00 h between June and...

AbstractFull Text

The objective was to determine the optimum percentage of Bos taurus (BT) genes for traits related to lactation performance of crossbred cows. Lactations (n=1,220) from 507 cows with percentage of BT genes ranging from zero to 87.5, were collected from a commercial farm in tropical Mexico. Variables ...

Abstract

The inclusion of the inbreeding coefficient (F) into the models to predict breeding values (BV) for Jersey (J) and Brown Swiss (BS) Mexican registered dairy cattle was studied. The conventional model including the fixed effect of herd-year-season, and the genetic additive and permanent...

AbstractFull Text

The objective was to determine the optimum percentage of Bos taurus (BT) genes on age at first-calving (AFC), days to first postpartum service (DFPS), days open (DO), and calving interval (CI) of Zebu cows and their crosses with European breeds. Calving records (n=1,704) from 570 cows with...

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...

Abstract

Research on FOOT AND MOUTH DISEASE was conducted in several countries. Samples of the virus from the outbreak in Mexico in 1950 were identified in tests carried out in England and Mexico as Type A. Antiserum of O, A, and C types from the Foot and Mouth Disease Research Institute, England were used...
