Five new recessive defects were discovered in Holsteins, Jerseys, and Brown Swiss by examining haplotypes that had a high population frequency but were never homozygous. The method required genotypes only from apparently normal individuals and not from affected embryos. Genotypes from the BovineSNP50 BeadChip (Illumina, San Diego, CA) were examined for 58,453 Holsteins, 5,288 Jerseys, and 1,991...

The objectives were to estimate the effects of various environmental factors on female calf survival Israeli Holsteins, economic value under conditions, genetic and variance components for cow using individual animal model, perform GWAS analyses first calving herd life after calving, trends since 1985, correlations with traits included in current breeding index, consequences inclusion national ...

Milk production in Thailand has been growing into an important agricultural sector, but it still faces numerous difficulties in environmental constraints. The main intention of this study was to identify significant environmental effects on production and fertility traits to give advices for farm management. Additionally, adjusting records for environmental impact is essential to define appropr...
