Project description:This study evaluated the effect of enhanced dietary intake during the early life period on the anterior pituitary transcriptome in bull calves. Between 2-12 weeks of age bull calves were offered either a high (HI; n=15) or moderate (MOD; n=15) plane of nutrition, with diets designed to evoke growth rates of 1.0 and 0.5 kg/day, respectively. At 12 wk of age, anterior pituitary tissue samples were harvested from all calves and subsequently subjected to mRNAseq.
Project description:This study evaluated the effect of enhanced dietary intake during the early life period on hypothalamic arcuate nucleus transcriptome in bull calves. Between 2-12 weeks of age bull calves were offered either a high (HI; n=15) or moderate (MOD; n=15) plane of nutrition, with diets designed to evoke growth rates of 1.0 and 0.5 kg/day, respectively. At 12 wk of age, arcuate nucleus tissue samples were harvested from all calves and subsequently subjected to mRNAseq.
Project description:The aim of the overall study was to investigate the development of immune competence in artificially reared dairy calves and in two breeds of naturally suckled beef calves over the first 168h of life. Dairy calves were fed 5% total body weight of colostrum, with beef calves monitored to ensure natural ingestion of colostrum. Blood samples were taken from all calves at 24h 48h 72h and 168h, and analysed for alterations to immunes genes.
Project description:This study evaluated the effect of enhanced dietary intake during the early life period on testes transcriptome in bull calves. Between 2-12 weeks of age bull alves were offered either a high (HI; n=15) or moderate (MOD; n=15) plane of nutrition, with diets designed to evoke growth rates of 1.0 and 0.5 kg/day, respectively. At 12 wk of age, testes parenchyma tissue samples were harvested from all calves and subsequently subjected to mRNAseq. Subsequent bioinformatics analyses revealed differential expression of genes invovled in cellular adhesion and immune function.
Project description:The aim of this study was to identify changes in metylome of parenchyma (PAR), fat pad (MFP) and liver in dairy calves. Our earlier results showed that feeding management regulates the dynamics of organ growth in preweaned heifers. We observed that a daily dose of 5.3 kg of milk replacer inhibits mammary gland development. Therefore, this research aims at evaluation of the influence of the nutritional level in the early life period of calves on the biological processes related to the development of the mammary gland through transcriptomic alterations.
