Background Brown adipose tissue(BAT)is known to be capable of non-shivering thermogenesis under cold stimulation,which is related to the mortality of *** the previous study,we observed that goat BAT is mainly located around the kidney at birth,and changes to white adipose tissue(WAT)in the perirenal adipose tissue of goats within one month after ***,the regulatory factors underlying this change is remain *** this study,we systematically studied the perirenal adipose tissue of goat kids in histological,cytological,and accompanying molecular level changes from 0 to 28 d after *** Our study found a higher mortality rate in winter-born goat kids,with goat birthing data *** we used thermal imaging revealing high temperature in goat hips at postnatal 0 d and gradually decrease during 28 *** is consistent with the region of perirenal BAT deposition and highlights its critical role in energy expenditure and body temperature regulation in goat ***,we found a series of changes of BAT during the first 28 d after birth,such as whitening,larger lipid droplets,decreased mitochondrial numbers,and down-regulation of key thermogenesis-related genes(UCP1,DIO2,UCP2,CIDEA,PPARGC1a,C/EBPb,and C/EBPa).Then,we used RNA-seq found specific marker genes for goat adipose tissue and identified 12 new marker genes for BAT and 10 new marker genes for WAT of ***,12 candidate genes were found to potentially regulate goat BAT *** mechanism of the change of this biological phenomenon does not involve a large-scale death of brown adipocytes and subsequent proliferation of white *** apoptosis may play a limited role,it is largely not critical in this transition *** We concluded that perirenal BAT plays a crucial role in thermoregulation in newborn goat kids,with notable species differences in the expression of adipose tissue marker genes,and we highlighted some potential marker genes
