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 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...
متن کاملFollicular cysts in dairy cows
Follicular cysts are the most critical reproductive disorder in dairy cows and disturb normal ovarian cycle, resulting in the prolonged interval from calving to conception. Therefore, this condition causes significant economic losses to the dairy industry. Two direct causal factors of cyst are suggested in this review; the disorder of ovulation and the delay of regression. The disorder of ovula...
متن کاملInteractions between negative energy balance, metabolic diseases, uterine health and immune response in transition dairy cows.
The biological cycles of milk production and reproduction determine dairying profitability thus making management decisions dynamic and time-dependent. Diseases also negatively impact on net earnings of a dairy enterprise. Transition cows in particular face the challenge of negative energy balance (NEB) and/or disproportional energy metabolism (fatty liver, ketosis, subacute, acute ruminal acid...
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...
