Genomic selection in multi-breed dairy cattle populations. Abstract Genomic selection has been a valuable tool for increasing the rate of genetic improvement in purebred dairy cattle populations. However, there also are many large populations of crossbred dai... ... Repository: BDPA Publication year: 2016
Repetition of estrus is the most frequent reproductive problem after breeding in dairy cattle from Rio de Janeiro, Brazil. ABSTRACT - Reproductive efficiency is one of the key elements for any milk production system to be successful. In this regard, reproductive management must be planned properly and the identification o... ... Repository: BDPA Publication year: 2017
Genetic analysis of productive and reproductive traits in multiple-breed dairy cattle populations. The objective of this work was to determine whether the random regression model using linear splines (RRMLS) is suitable to estimate the genetic parameters for productive and reproductive traits of a... ...

Study of the impact of breeding seasons in the dynamics of dairy goat herds. Abstract: The competitiveness in the animal production field has forced the smaller activities to be more efficient when compared to big business of the agro-industries. The dairy goat production is o... ... Repository: BDPA Publication year: 2009
Estrus induction in the non-breeding season is not associated with hydrometra in dairy goats. Abstract: This study aimed to compare the prevalence of hydrometra (HD) at the end of the reproductive season in goats subjected (HORM and LIGHT) or not (Control-HORM and Control-LIGHT) to estrus indu... ...

Genetic parameters for milk production traits and breeding goals for Gir dairy cattle in Brazil. The present study defined breeding goals and proposed selection indices for milk production and quality traits of Gir dairy cattle. The results indicate that milk component traits should be included i... ... Repository: BDPA Publication year: 2015
Providing genetics for the dairy industry in the tropics - the Brazilian Dairy Gir Breeding Program. Milk production is usually challenging under tropical environments. Heat stress and/or recurrent parasite infestations frequently cause cattle?s reduced fitness and productivity. As a way to overcome... ... Repository: BDPA Publication year: 2022
Evaluation of brazilian dairy goat breeding programs. Abstract: This work aimed to evaluate the genetic and economic gains for two selection schemes for dairy goats in Brazil. Analyses were performed by ZPLAN software. The traditional scheme had no econo... ... Repository: BDPA Publication year: 2014
Effects of feeding level and breed composition on intake, digestibility, and methane emissions of dairy heifers. The dairy Nutrients Requirements of Cattle (NRC) was developed using data from purebred Holsteins and it might not accurately predict the performance of crossbred cattle. Our objectives were to evalua... ... Repository: BDPA Publication year: 2021
Spatialization of climate, physical and socioeconomic factors that affect the dairy goat production in Brazil and their impact on animal breeding decisions. Abstract: Brazil has high climate, soil and environmental diversity, as well as distinct socioeconomic and political realities, what results in differences among the political administrative regions o... ...
