  A two phase study was conducted using a total of forty-five West African Sheep lambs. The first phase was from birth to one year of age and the second phase was from one year to four years of age. The lambs were grouped using their dental arrangements at the upper and lower jaws, respectively. Their body measurements were carried out at both the experimental and field levels. Body length, heart girth, height at withers and chest depth were measured. Experimental lambs were taken at birth, weaning, one year age and adult animals at one to four years of age. The effect of sex and birth type was investigated. Similarly, the same measurements were taken for the surveyed animals from birth to one-month of age and for adult animals. The study indicated that surveyed animals exceeded experimental animals in all the body measurements taken.

  The study was conducted at University of Nyala Farm. 75 females and 10 males were selected with typical characteristics of the breed to study their reproduction and production traits. Flock statistics for ewes lambing in the winter and wet-summer seasons were recorded and then some reproductive traits were estimated such as conception rate, barrenness rate, fertility, litter size, abortion, lambing rate, twining rate and male ratio. The mean gestation length was 150.44?2.64 days ranging between145-156 days. The effect of ewe age on gestation length was non significant (p>0.05). Male and single born lambs had longer gestation period than female and twinborn lambs. Similarly, overall birth weight of lambs was found to be 2.90?0.50 kg, it was 3.18?0.49 kg for males and 2.70?0.41 kg for females. They were weaned at approximately 3 month of age with an average of 11.55?2.19 kg for males and 9.97?2.12 kg for females, single born lambs were heavier than twin born lambs for both sexes. The average pre-weaning growth rate was 90.00 gram per day, males and single born lambs were grew faster than females and twins born lambs. Similarly, growth rate was determined for the periods of 3 to 6, 6 to 9 and 9 to12 months of age, they observed that single and male lambs exceeded twins and females lambs in growth rate.

  The West African sheep was originated in the West African countries, brought to Sudan in 1930. These breeds include (Uda, Sankara and Weila) strains. They are normally reared to gather as mixed pastoral flocks, followed different routes during summer and autumn seasons. In the first phase of this study 75 females and 10 males were selected with typical characteristics of the breed, brought to the University of Nyala experimental farm. In the second phase basic information from tribal breeders and their sheep flocks were collected. For each phase flock statistics were recorded and then some reproductive and productive traits were estimated. Season and age effect on mortality of sheep flock was estimated. Likewise feed lot experiment was done to examine the possibility of sheep for improvement of meat production. Body length, heart girth, height at withers and chest depth were measured for lambs at birth to one year age and similar measurements were taken for adult flocks.

  eventeen male Ostrich chicks (Ostruiothio, Camelus camelus) aged one month old were brought from Radom National Park to the research farm of University of Nyala, both in Sudan, and reared indoor, concentrate rations were formulated and provided ad-libitum and water equally supplied. During the study period, chick behaviour were observed, body weight gained (g/day), feed intake (g/day), water consumption (liter/day) and feed conversion ratio (FCR) were found to be 178.64, 447.91, 4.18 and 2.39, respectively. Rapid growth rate during the age of 2 to 4 months resulted to leg deformation which eventually leads to the death of some chicks with mortality rate 41.20% at the end of the experiment. The body measurements at different ages of chicks were highly significant (P< 0.05). There were high positive correlations between live weight and other parameters estimated (shank diameter and length, nick diameter and length, wing length, body length, heart girth and bird high).

  The genetically fat Anka and lean Rugao chicken breeds were used for this study, both are reared in the same environment and management system. Body weight and abdominal fat weight were determined at 12 weeks of age. A polymerase chain reaction single strand conformation polymorphism technique was applied to detect mutation in intron 8 of lipoprotein lipase gene. Hardy Weinberg Equilibrium (HWE) test shows that allele frequency was significantly (p<0.01) different in Rugao population in locus LPL10 and non significantly different in Anka population. In addition chi-square test shows that populations were significantly (p<0.01) differed from each other. Body weight in fat breed was significantly (p<0.05) different between LPL genotypes in LPL9 and LPL10 loci. However, the abdominal fat was significantly (p<0.05) different in LPL10 locus. In addition lean breed shows non significant difference on body weight and fat weight. Genotype effect within two breeds showed that body weight and fat weight in LPL9 and LPL10 loci were significantly (p<0.05) higher in heterozygous AC compared with homozygous AA.
