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

Survival analysis and reproductive performance of Dorper x Tumele sheep [PDF]

Heliyon, 2020
Productivity and profitability of sheep farming are highly influenced by lamb survival and ewe reproductive performance. Thus, this study was conducted to evaluate the survival and reproductive performance of crossbred sheep. Data collected from 2009 to 2018 from Sirinka sheep breeding stations were utilized for this study.
