Nutritional Level and Type of Feed on the Reproductive Performance of Ewe and Its Effects on Offspring. [PDF]

Reprod Domest Anim
ABSTRACT The amount and source of nutrition are important factors that influence an ewe's reproductive ability, but the effects of diet on the reproductive performance of its offspring are unclear. This study aimed to investigate the impact of maternal nutrition (level of nutrition and source) on the reproductive performance of ewes and their female ...

Comprehensive Analysis of PAPPA2 Expression and Genetic Variants in Sheep and Their Association With Litter Size. [PDF]

Vet Med Sci
ABSTRACT Background The PAPPA2 gene encodes a metalloproteinase critical for regulating insulin‐like growth factor (IGF) bioavailability through cleavage of insulin‐like growth factor‐binding protein 5 (IGFBP5). While its role in human and murine reproduction is documented, its function in sheep reproductive traits remains underexplored. Objective This

Preliminary Results about Lamb Meat Tenderness Based on the Study of Novel Isoforms and Alternative Splicing Regulation Pathways Using Iso-seq, RNA-seq and CTCF ChIP-seq Data

Foods, 2022
Tenderness is an important indicator of meat quality. Novel isoforms associated with meat tenderness and the role of the CCCTC-binding factor (CTCF) in regulating alternative splicing to produce isoforms in sheep are largely unknown.
