Whole-genome comparative analysis reveals genetic mechanisms of disease resistance and heat tolerance of tropical cattle breeds.

cattle breeds have been naturally selected for thousands of years for disease resistance and thermo-tolerance. However, the genetic mechanisms underlying these specific inherited characteristics must be elucidated. Hence, in this study, a whole-genome comparative analysis of the cattle breeds Kangayam, Tharparkar, Sahiwal, Red Sindhi, and Hariana of the Indian subcontinent was conducted.

Meta-analysis of mammary RNA seq datasets reveals the molecular understanding of bovine lactation biology.

A better understanding of the biology of lactation, both in terms of gene expression and the identification of candidate genes for the production of milk and its components, is made possible by recent advances in RNA seq technology. The purpose of this study was to understand the synthesis of milk components and the molecular pathways involved, as well as to identify candidate genes for milk production traits within whole mammary transcriptomic datasets. We performed a meta-analysis of publically available RNA seq transcriptome datasets of mammary tissue/milk somatic cells.

Modulation of post-hatch growth and immunity through in ovo supplemented nutrients in broiler chickens.

Background: Early post-hatch growth and immunity were assessed through in ovo supplementation of nutrients: amino acids (AA), trace elements (TE), fatty acids and vitamins (FAV) grouped under humoral immunity (HI) or cell-mediated immunity (CMI) on the 18th day of incubation at the broad end of the egg using a 25 mm needle.

Results: Hatchability in AA groups was better than TE and FAV groups. CMI groups had better hatchability than HI groups.
