Twenty-four kids were studied for effects of early weaning. (d 14) on body weight, concentrations of DNA, RNA and alkali soluble proteins in muscle and liver, and serum concentrations of thyroxine and triiodothyronine. Body weight increased (P<0.05), DNA, RNA and protein content of muscle decreased (P<0.05), nucleic acid concentration of liver increased (P<0.05) during the first 2 wk after birth, and thyroid hormones decreased (P<0.05) until d 14. Contents of DNA and RNA in muscle decreased exponentially. Increases in nucleic acids in the liver suggest that hepatic function had a higher priority for nutrition than the cumulative and proliferative process of muscular growth during weaning. Decrease of extrathyroidal conversion of T4 to T3 suggests an adaptive mechanism to prevent excessive loss of metabolically active tissue during early weaning. Weaning goats as early as 14 d, may result in loss of cellularity, even though LBW increases. |
