“…Heterosis estimate for birth weight was lower compared to 10.6%, 17.1%, 15.3% and 23.1% heterosis for birth weight of crossbreds of Nubia, Saanen, Toggenburg and Alpine sires with local goat does from Northern Mexico, respectively [13] and lower to 46.67% heterosis estimate of crossbred kids of Boer and PE goat [14]. Heterosis values observed in this study are also lower than those estimated for birth weight, weaning weight and pre-weaning growth rate in crossbred kids between Aradi Saudi goats and Syrian Damascus goats which ranged from 7.8% to 14.5% [15]. Heterosis estimates for weaning weight (6.28%) and (5.66%) in crossbreds of Boer and Kiko goats and in crossbred of Boer and Spanish goats, respectively, were higher than those observed in this study [16].…”

The study estimated heterosis of growth traits from crossbred progeny of MalyaxSukuma goats and heritability, genetic correlation and phenotypic correlation for growth traits of Malya goats in Maswa, Tanzania. The objective was to explore strategies for crossbreeding Malya goats with the Sukuma goats. Growth performance data recorded during the implementation of a crossbreeding project for parent breeds and crossbred off-springs were used to estimate the parameters. Positive heterosis was observed for birth weight (8.19%), yearling weight (9.59%), post-weaning growth rate (19.26%)

“…These improvements accomplished in some crossbred bucks of the current study could be explained on the basis that crossbreeding influences positively growth rate of the whole body. This leads to an early maturation of the hypothalamus and the pituitary, which directly manipulates the growth of testes and finally the performance of the bucks [ 22 ]. There was a positive genetic correlation (0.36) between the volume of ejaculate and body gain in paternal lines of rabbits selected for growth rate [ 23 ].…”

The aim of this investigation was to evaluate the semen quality traits of purebred male rabbits and their crosses under subtropical Egyptian conditions. A full 3 x 3 diallel crossing was performed for producing the first generation progeny of New Zealand White (N), Flander (F) and Rex (R) breeds. The highest ejaculate volume (p< 0.05) and percentage of live sperms (p<0.01) with the lowest percentage of sperm cell morphological abnormalities (p<0.05) had been recorded in the NF bucks. Moreover, they possessed positive estimates of direct heterosis for ejaculate volume, mass motility (Mm), individual motility (Im) and sperm cell concentration (SCC). On the contrary, pH had negative estimates of direct heterosis in all crosses and their reciprocal. Semen pH was negatively correlated with SCC (r = -0.18), Mm (r = -0.13) and Im (r = -0.23). In conclusion, the superiority of crossbreeding was particularly obvious in the New Zealand White x Flander males, which cumulated heterosis and favorable maternal effects of the Flander dams.

“…This indicated there was a crossbreed resistance of F1 BoerPE. Crossbreed resistance means that there are physiological efforts to respond to the results of crossbreeding [17]. Physiological efforts of crossbreeding resistance related to improving cell performance for increased productivity.…”

Cases of clinical reproduction in crossbred cattle have been reported with the incidence of decreased reproductive performance. Crossbreeding resistance is usually followed by low immunity. Blood profile is one of the parameters that illustrate the immunity of livestocks. Goat crossbreeding resistance has never been studied. The purpose of this study was to analyze the crossbreeding resistance of the F1 BoerPE goat and her mothers by analyzing their blood profile. F1 BoerPE goat is the offspring of crossbreeding between Boer buck with PE goat. The research method was case study. The primary data were obtained from examination of blood profile and Physiological Status of F1 BoerPE goat and her mothers. The secondary data obtained from recording age and body weight. The blood profile data were analyzed by t test. The observed blood profile indicators were neutrophils, monocytes and lymphocytes. The results showed that theÂ physiological status of F1 BoerPE goat and her mothers was not significant. Nevertheless, the number of neutrophils, lymphocytes and monocytes was significantly different (pË‚0.01). The average (%) number of neutrophils, lymphocytes and monocytes of PE goats was 37.92 Â± 1.37; 51.85 Â± 1.4; 3.87 Â± 0.21. while the average blood profile of F1 BoerPE was 46.16 Â± 2.1; 58.06 Â± 3.4; 5.51 Â± 0.18. The average number of neutrophils, lymphocytes and monocytes F1 BoerPE goat was higher compared to the parent. It is indicated that there were crossbreeding resistance of F1 BoerPE goat.
