Decreased concentration of plasma leptin in periparturient dairy cows is caused by negative energy balance.
Dairy cows suffer from an intense energy deficit at parturition due to the onset of copious milk synthesis and depressed appetite. Despite this deficit, maternal metabolism is almost completely devoted to the support of mammary metabolism. Evidence from rodents suggests that, during periods of nutritional insufficiency, a reduction in plasma leptin serves to co-ordinate energy metabolism. As an...
متن کاملEffect of insulin and growth hormone on plasma leptin in periparturient dairy cows.
After parturition, dairy cows suffer from an intense energy deficit caused by the onset of copious milk secretion and an inadequate increase in voluntary food intake. We previously showed that this energy deficit contributes to a decline in plasma leptin. This decline mirrors that of plasma insulin but is reciprocal to the profile of plasma growth hormone (GH), suggesting that both hormones may...
متن کاملExpression of metabolic sensing receptors in adipose tissues of periparturient dairy cows with differing extent of negative energy balance.
We recently showed that the mRNA expression of genes encoding for specific nutrient sensing receptors, namely the free fatty acid receptors (FFAR) 1, 2, 3, and the hydroxycarboxylic acid receptor (HCAR) 2, undergo characteristic changes during the transition from late pregnancy to lactation in certain adipose tissues (AT) of dairy cows. We hypothesised that divergent energy intake achieved by f...
متن کاملpromoter analysis of effective genes in negative energy balance in dairy cows
this study was done to gain insights into transcriptional regulation of negative energy balance (neb) assoctiated genes. overexpressed genes in neb were identified using microarray and rna-seq data and promoter analysis of these overexpressed genes was applied to identify novel transcription factors. moreever, string database was used to construct a regulatory network of identified transcriptio...
