This research aimed to determine the effects of body weight, the body condition score (BCS), body measurements, birth type, birth weight and sex on the gestational length in sheep. The lowest and highest gestational lengths were found to be 148.90 and 151.41 d respectively. It is thought that the use of the BCS, which is easily applied by the breeder, will have a positive effect on determining the bodily reserves of sheep and the reproductive efficiency as well as on obtaining healthy lambs.

The objective was to find whether cow growth, milk performance, and behaviour are affected by rearing conditions until weaning after a milk-fed period of 84 d. Holstein heifers were assigned to one of three treatments: SM, pen with mother to 21st day, then group pen; SN, with own mother, then in pen with nursing cow; H, in hutch from 2nd to 56th day. The SN group tended to have the highest production of milk for 305 d and crossed the maze the fastest.

The mechanism of lipid metabolism is complex, and the manipulation of fat storage for lean meat production is very important in the sheep-breeding industry. The present study aimed to study the genetic profiles of fat tissues and to discover the diversity in the genetic mechanisms defining fat deposition between two morphologically different sheep breeds. Analysis of the diversity of fat deposition may aid the recognition of genes and pathways responsible for the formation of tail fat.

In this study, we examine the correlation between the expression of GPAM and adipogenesis in bovine mammary epithelial cells (bMECs). Additionally, three novel polymorphisms are identified within the bovine key functional domain of GPAM. GPAM plays a pivotal role in the regulation of phospholipid levels and cellular triacylglycerol, and its mutations could serve as a competent molecular marker that could be utilized for marker-assisted selection.
