RESULTS CONCERNING THE GROWING DYNAMICS IN YOUNG SHEEP HYBRID SUFFOLK x TSIGAI AND TSIGAI, FROM LAMBING TO WEANING

Abstract

The comparative results of the growing dynamics of the Suffolk x rusty Tsigai hybrids, and rusty Tsigai pure breed young sheep from lambing to weaning are comparatively presented in this paper. The average values, variability estimates and differences between the average values of both breed structures and those performed by the offspring of three Suffolk rams used in reproduction are apart presented by male and female young sheep. The following traits were recorded: the body weight (at lambing, 60 days of life, and weaning), total gain and average daily gain from lambing to weaning. The average weaning age was between 84 and 89 days, function of sex. Positive differences, statistically assured were recorded in Suffolk x Tsigai hybrids of both sexes (p<0.01 and p < 0.001) compared to rusty Tsigai young sheep in all analyzed traits, except lambing weight. Statistically not significant differences were recorded in all analyzed traits between the hybrid offspring of the three Suffolk rams used for reproduction, and also between male and female offspring within both breed structures.
