| Abstract |
The present study was carried out by using 217 does and 147 kids of Zaraibi goats. The aim of the study was to estimate some productive and reproductive traits and their possible associations with biochemical marker genes in blood in Zaraibi goats. The effects of season of birth were highly significant on each of age at first kidding, kidding interval, live weights at birth and at weaning and pre-weaning kid morality and significant on each of litter size at birth, abortion and six months body weight (SMW). The effects of year of birth were highly significant on each of age at first kidding, litter size at weaning, litter weights at birth and at weaning, live weights at birth and at weaning, abortion, mortality rate, survival rate, birth weight (BW), pre-weaning growth rate and pre-weaning kid mortality and significant on each of litter size at birth, weaning weight (WW) and daily gain. The effects of type of birth were highly significant on each of age at first kidding, WW and daily gain and significant on, live weight at birth. The effects of parity were highly significant on each of litter size at weaning, litter weights at birth and at weaning, live weights at birth and at weaning, abortion, mortality rate, survival rate, BW, WW, SMW, daily gain and pre-weaning kid mortality, significant on litter size at birth and pre-weaning growth rate. The effects of sex of kids were highly significant on live weight at weaning, WW, SMW and daily gain and significant on litter weight at weaning and BW. The effects of litter weight at birth were highly significant on each of age at first kidding, live weights at birth and at weaning, abortion, mortality rate, survival rate and pre-weaning kid mortality. The effects of weaning weight and growth rate of dam were highly significant on age at first kidding.
Marker genes polymorphism for Zaraibi goats were, Immunoglobulin M (IgM; 205,000), Immunoglobulin G (lgG; 116,000) Immunoglobulin p (IgP; 97,400), Albumin (A.; 66,000),α1 Antitrypsin (Ant.T.; 45,000), Carbonic Anhydrase Erythrocytes (C.An.Er.; 29,000), Trypsinogen (T.; 24,000) and Trypsin Inhibitor (Tr.I.; 20,000), by using one-dimensional sodium dodecyl sulfate polyacrylamide slab gels electrophoresis (SDS-PAGE) with high molecular weight standards, as reference bands. The effect of IgP marker gene was highly significant on pre-weaning kid mortality and significant on abortion. The effect of A. marker gene was highly significant on each of kilograms produced per doe at birth and at weaning, mortality rate and survival rate. The effect of Ant. T. marker gene was significant on BW. The effect of C.An.Er. marker gene was highly significant on pre-weaning growth rate and significant on age at first kidding. The effect of Tr.I. marker gene was highly significant on litter size and litter weight at birth and at weaning.
