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...
Ghrelin is a regulatory peptide in glucose homeostasis in animal species. Its effect in the avian embryo is unclear. The aim of this study was to investigate the effects of in ovo ghrelin administrati...
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...
This study was conducted to investigate the effects of increasing levels of protein-free energy supplementation on blood glucose, urea nitrogen, insulin and gene expression of hepatic phosphoenolpyruv...
Pigs fitted with ileal T-cannula in the terminal ileum were used to study the effect of synthetic amino acids (AA) added to a nitrogen-free diet on endogenous losses. We compared the obtained data wit...
This study was carried out to investigate the effects of intraruminal infusion of propionate on ruminal fermentation characteristics and blood hormones and metabolites in Hanwoo (Korean cattle) steers...
Dietary protein restriction affects lipid metabolism in rats. This study was performed to determine the effect of a low protein diet on hepatic lipid metabolism and insulin sensitivity in growing male...
Insulin-responsive glucose transporter 4 (GLUT4) is a member of the glucose transporter family and mainly presents in skeletal muscle and adipose tissue. To clarify the molecular structure of porcine ...
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....
Twelve SuffolkSmall-tail-Han male sheep (body weight 21-26 kg), aged four months, were used to study the effects of volatile fatty acids (VFA) on IGF-I (insulin-like growth factor-I) , IGFBP-3...
The aim of the present study was to determine if some naturally-occurring substitutions of amino acid residues of insulin could act differentially within the central nervous system (CNS) of neonatal c...
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 ...
Healthy multiparous Holstein-Friesian cows (n = 22, parity: 2–4) from a large-scale dairy herd in Hungary were subjected to an intravenous glucose tolerance test 10–15 days after calving. AluI genot...
The glucose tolerance and pancreatic insulin secretion response to glucose in sheep fed on germinated sorghum grain were determined using an intravenous glucose load. Twelve male Thin Tail sheep (an I...
