A comparative study was performed to investigate the efficacy of KiFAY as a feed additive on performance parameters, thyroid, and pancreatic hormone levels in broilers. Ninety birds (Vencobb 400) were...
The effect of the insulin-like growth factor 2 (IGF2) gene polymorphism – a g.292C>T transition in exon 2 on feed uptake and conversion, growth rates, and meat production traits in Polish Holstein-Fri...
The principal objective of this experiment was to determine the effects of dietary betaine on IGF-I, IGFBP-3 and IGFBP-1 secretion and IGF-I mRNA gene expression in the serum and liver of laying hens....
A single nucleotide polymorphism (SNP) site, alleles A and C, within promoter region of insulin-like growth factor 1 gene (IGF1) showed significant association with chicken growth, body composition a...
Nutrient availability may control muscle growth directly and indirectly through its influence on regulatory factors. We analyzed the effects of nutrient availability on the breast muscle insulin-like ...
There is a constant increase in demand for large numbers of high-quality oocytes of domestic mammals for various reproductive biotechnologies. Prolonged in vitro culture represents one of the many pos...
Insulin-like growth factor binding protein-3 (IGFBP-3) gene is a structural gene associated with the growth and development of the animals. The present investigation was carried out to unravel nucleot...
The effect of refeeding with various single essential amino acids on the recovery of plasma insulin-like growth factor-I (IGF-I) concentration in fasted young chickens was examined. Young chickens (29...
