The purpose of this study was to measure the growth and body composition of pigs during normal or compensatory growth from 60 to 100 kg, without (cont) or with ractopamine (rac) supplementation (20 mg/kg of diet). Thirty-four pigs were scanned by dual X-ray absorptiometry (DXA) for body composition analysis at a starting weight of 61.4 ± 0.3 kg and at a final weight of 100.4 ± 0.5 kg. Half the ...
Compensatory growth is a physiological phenomenon found in both humans and animals. However, the underlying mechanisms are unclear. In this study, for the first time, we investigated the role of microbiota in compensatory growth induced by protein restriction using a rat model. Weaned Sprague-Dawley rats were fed a low protein diet (L group), a normal protein diet (N group) and a low protein di...
This experiment was conducted to investigate the effects of intensity of restricted early feed and increased nutrient density after restriction period on performance and compensatory growth in broilers. Two hundred and eighty-eight broiler (Lohman) chicks in a completely randomized design in a 2*3 factorial arrangement of treatments were employed. Birds were fully fed from 7 to 13d or 100% of a...
Organisms usually grow slower than their maximum potential under a given set of conditions, suggesting that fast growth carries a corresponding fitness cost. A pattern of growth that might influence such costs is compensatory (or catch-up) growth, where individuals grow faster than expected. One form of compensatory growth occurs when small individuals grow faster for their size than do large i...
Compensatory renal growth after unilateral ureteral obstruction. The accumulation of bulk renal protein, RNA and DNA was studied in mice during a 35-day period of accelerated renal growth in the kidney contralateral to that obstructed by acute ureteral ligation. Control mice were sham-operated and nonoperated. RNA was determined by the method of Monroe and Fleck, DNA after Ceriotti and protein ...
