Beta-hydroxybutyric acid(BHBA),as one of the main metabolic ketones in the rumen epithelium,plays critical roles in cellular growth and *** ketogenic capacity is associated with the maturation of rumen in young ruminants,and the exogenous BHBA in diet may promote the rumen ***,the effects of exogenous BHBA on rumen remain *** is the first study to investigate the mechanisms of BHBA on gene expression and metabolism of rumen epithelium using young goats as a model through multi-omics ***-two young goats were divided into control,low dose,middle dose,and high dose groups by supplementation of BHBA in starter(0,3,6,and 9 g/day,respectively).Results demonstrated the dietary of BHBA promoted the growth performance of young goats and increased width and length of the rumen papilla(P<0.05).Hub genes in host transcriptome that were positively related to rumen characteristics and BHBA concentration were *** upregulated hub genes including NDUFC1,NDUFB4,NDUFB10,NDUFA11 and NDUFA1 were enriched in the gene ontology(GO)pathway of nicotinamide adenine dinucleotide(NADH)dehydrogenase(ubiquinone)activity,while ATP5ME,ATP5PO and ATP5PF were associated with ATP ***-PCR revealed the expression of genes(HMGCS2,BDH1,SLC16A3,etc.)associated with lipolysis increased significantly by BHBA supplementation(P<0.05).Metabolomics indicated that some metabolites such as glucose,palmitic acid,cortisol and capric acid were also increased(P<0.05).This study revealed that BHBA promoted rumen development through altering NADH balance and accelerating lipid metabolism,which provides a theoretical guidance for the strategies of gastrointestinal health and development of young ruminants.

Animal Nutrition 2015年第4期1卷 344-348页

作者： jianmin chai Qiyu Diao Haichao Wang Yan Tu Xiaojing Tao Naifeng Zhang Feed Research Institute of Chinese Academy of Agricultural Sciences Key Laboratory of Feed Biotechnology of the Ministry of Agriculture Jiangsu Taizhou Helen Sheep Ltd.

This study was conducted to investigate the effect of weaning age on growth performance, nutrient digestion and metabolism, and serological indicators, and to obtain an optimal weaning age in Hu ***-eight newborn Hu lambs(birth weight, 2.53 ± 0.14 kg) were randomly divided into 4 groups. The lambs in control group(ER) suckled their dams. The lambs in other three experimental groups were weaned on milk replacer at 10.20, and 30 days of age(EW10, EW20, and EW30 groups),respectively. The results were as follows: 1) lambs in EW10 and EW30 groups had a lower(P 0.05) among groups; however, the apparent digestibility and deposition of calcium in early weaned lambs were lower(P < 0.05) than those in ewe-reared lambs. 4)The albumin content in EW30 group was lower(P < 0.05) than that in ER group; the globulin content in EW30 group was higher(P < 0.05) than that in other groups; the content of serum insulin-like growth factor-1 in weaned lambs tended to increase compared with lambs in ER group. Finally, the growth rate of lambs decreased within 10 days post-weaning, but early weaning boosted creep feed intake, leading to better growth and health later in life. The Hu lambs can be weaned on milk replacer and creep feed at 10 days of age.
