Article Synopsis
- The study focuses on identifying genes linked to milk production in crossbred Gir × Holstein (Girolando) dairy animals, as most genetic research has been on pure breeds.
- Researchers performed a genome-wide association study (GWAS) on 337 Girolando animals, analyzing over 45,000 single-nucleotide polymorphisms (SNPs) to find associations with 305-day milk yield while adjusting for various factors.
- The study identified 52 significant SNPs associated with milk production, including NUB1 and SLC24A2, suggesting these markers could help predict genetic potential for milk yield in Girolando cows.
The aim of this study was to evaluate the effect of daily biotin supplementation on the mineral composition and microstructure of the abaxial hoof wall in dairy heifers. The heifers were housed on a concrete floor and fed for weight gain more than 800 g per day, which is a challenging environment for the hoof. Twelve crossbred dairy heifers (Jersey × Holstein) were divided into two treatment groups.

Blood samples were collected from the animals of the School of Agrarian and Biological Sciences of the Pontifical Catholic University of Goiás, two males and two females of pure breed. These samples were submitted to the cell culture method to study metaphase chromosomes.
