0.001). The average TMY was 1429 Kg. The heritability estimate of TMY was 0.25. The regression of TMY on year of calving showed a positive trend (+67 kg per year of calving). Also, genetic trend was positive (+12.55kg per year of birth). In conclusion, although the trend in the estimated breeding values was positive, it still did not lead to adequate change required in the average milk production due, probably, to inadequate feeding and/or impaired management of the herds.]]>

0.05). As well, 2–week castrated kids had the lowest density of sebaceous glands compared with entire kids and 6 – month castrated ones. Histologically, the parietal glands of entire kids appeared highly modified and larger occupying the major part of the dermis with marked secretory activity than other regions as well as castrated kids. Sweat and sebaceous glands in parietal region of Baladi bucks are the major source of buck odor. Furthermore, the attained results revealed that castration of kids at an early age of life (2-weeks of age) plays an important role in reducing male odor.]]>
