  A study was carried out to determine the effects of varying levels of whole cottonseed on feed intake, weight gain and blood parameters in FriesianxBunaji and Bunaji heifers. Twenty FriesianxBunaji and 24 Bunaji pre-pubertal heifers were divided to 4 groups of 5 and 6 animals/group. Animals in each group were fed 1 of 4 experimental concentrate diets containing 0, 25, 50 and 75% whole cottonseed for 140 days. The result of the study showed that concentrate intake declined with increase in the level of whole cottonseed in dieting averaging 4.2, 3.3, 3.1 and 2.9 kg head -1day -1 in FriesianxBunaji fed 0, 25, 50 and 75% whole cottonseed diets, respectively. The corresponding intake figures for the Bunaji heifers were 3.1, 2.9, 2.5 and 2.2 kg head -1 day -1. Mean daily weight gain were 0.59, 0.59, 0.48 and 0.64 kg in FriesianxBunaji and 0.48, 0.41 and 0.50 C kg in Bunaji heifers fed 0, 25, 50 and 75% whole cottonseed levels, respectively. Changes in blood parameters were not significant in both FriesianxBunaji and Bunaji heifers across treatments. The study showed that heifers could be fed diets containing up to 75% whole cottonseed, respectively without adverse effects.

  Twenty Friesian x Bunaji crossbred and twenty-four Bunaji prepubertal heifers were fed 4 diets containing 0, 25, 50 and 75% whole cottonseed to determine effect of varying the level whole cottonseed on onset of puberty, response to oestrus synchronization with PGF and artificial insemination. The animals were fed the diets for 140 days. At the end of the feeding trials, oestrus synchronization was carried out on all the animals using PGF, injected intramuscularly in 2 doses of 2 mL each given 13 days apart. Compared to animals on the control diet (0% whole cottonseed diet), there was a slight delay in onset of puberty (age at first detection of palpable ovarian structures and first oestrus) with inclusion of whole cottonseed in the diet. Following oestrus synchronization with PGF, interval from treatment to onset of oestrus increased. Compared to the animals on the control diet, oestrus response rates, oestrus activities (vis-à-vis number of mounts) and heat duration declined significantly (p<0.05) in both Friesian x Bunaji and Bunaji heifers with increasing level of whole cottonseed in the diet. Level of whole cottonseed had no effect on conception rates of Friesian x Bunaji heifers. However, there was significant decline in pregnancy rates of animals fed 25, 50 and 75% whole cottonseed diet compared to the control (averaged pregnancy rates = 100, 80.3, 40.2 and 80.3% for the Friesian x Bunaji and 66.7, 50.0, 50.0 and 50% for the Bunaji on 0, 25, 50 and 75% levels of whole cottonseed, respectively).

  Twenty-five cocks consisting of 14 red and 11 white Shikabrown cocks selected on the basis of body weight and antibody titres were infected with 0.2 ml of 106.0 EID50 of a velogenic Kudu 113 strain of Newcastle disease virus intranasally and intraocularly. Twenty-five cocks consisting of 14 red and 11 white Shikabrown cocks served as controls. Cloacal temperatures, live weights and semen samples of both control and infected cocks were taken weekly for six weeks. Semen was collected by abdominal message and evaluated for volume, colour, motility, concentration, percent live spermatozoa and percent total spermatozoa abnormalities. The semen volume of infected red cocks showed a general increase over that of control red cocks. The semen volume of the control white Shikabrown cocks was significantly (p<0.05) higher than that of the infected white cocks. The white Shikabrown cocks had higher semen volume than the red Shikabrown cocks. The red Shikabrown cocks had slightly better semen colour than the white Shikabrown cocks. The control white cocks had better (p<0.05) spermatozoa motility than the infected white cocks, while the infected red cocks had significantly (p<0.05) spermatozoa motility than the control red cocks. Generally, the white Shikabrown cocks had better spermatozoa motility than the red cocks. The spermatozoa concentration of the control white cocks was consistently higher than that of the infected white cocks; the reverse was the case with the red cocks where the spermatozoa concentration of the infected red cocks was higher than that of the control red cocks. The white cocks had higher spermatozoa concentration than the red cocks. The control white Shikabrown cocks had significantly (p<0.05) higher percent live spermatozoa than the infected white cocks. The infected red Shikabrown cocks had significantly (p<0.05) higher percent live spermatozoa than the control red cocks. The control white cocks had significantly (p<0.05) higher percent live spermatozoa than the control red cocks. The infected red and white Shikabrown cocks had higher percentage total spermatozoa abnormalities than the control red and white cocks. It can be concluded from this study that the white Shikabrown cocks had better semen quality than the red Shikabrown cocks. It is recommended that breeder cocks be routinely vaccinated against Newcastle disease to ensure that the level of antibodies is high enough to prevent adverse effects on semen quality.

  Fifty 20 week old Shikabrown cocks consisting of 22 red Shikabrown and 28 white Shikabrown cocks were purchased from the National Animal Production Research Institute, Shika and used for this study. Twenty-five of the cocks made up of 12 red and 13 white cocks selected on basis of weight were infected with 2 ml of 106.0 EID5.0 of a Velogenic Kudu 113 strain of Newcastle disease virus intranasally and orally. The remaining twenty-five cocks made up of 14 red and 11 white served as control. Blood samples were taken from the wing veins of both infected and control cocks and centrifuged in a Hermle Z364 centrifuge at 251.6 g for packed cell volume, total protein and Newcastle disease antibody titres. There was no significant difference in the packed cell volume of the control and infected red Shikabrown cocks. Similarly there was no significant difference in the packed cell volume of the control and infected white Shikabrown cocks, although the infected cocks had slightly lower values. Total protein did not show any significant difference between the control and infected red cocks and between the control and infected white cocks. The antibody titres of the control red and white cocks were significantly (p<0.05) lower than those of the infected red and white cocks. This finding showed that the challenged red and white cocks had high antibody titres and a slight drop in packed cell volume. The mean antibody titres of 1.9 ±0.7 to 4.6 ±0.4 log2 provided protection to the Shikabrown cocks against the velogenic Newcastle disease virus since none of the challenged cocks died. This study suggests that in an endemic environment like Zaria, poultry farmers keeping Shikabrown chickens should vaccinate them against Newcastle disease. Challenging the red and white Shikabrown cocks with the velogenic Newcastle disease virus increased their protection against the Newcastle disease.

  The effect of progesterone (P4) on egg production was investigated using twenty female guinea fowls raised on deep litter. The birds were given feed and water ad-libitum. They were routinely bled by wing jab between the hours of 9.00 and 10.00 am twice a month for P4 determination. Sera harvested from the samples were stored at -20°C until assayed for P4 by Radio-Immuno-Assay method (RIA). Egg production had a very high (p<0.001) and positive correlation with progesterone level. A high value of coefficient of determination (R2 value) was observed, which implies that there is a high accuracy of prediction of egg production from progesterone level.

  Fifty 20 weeks old Shikabrown (SB) cocks consisting of 22 red and 28 white SB cocks were purchased from the National Animal Production Research Institute Shika. The cocks were fed on a diet of layers mash with 18% crude protein, 95.6% dry matter, 17.1% crude fibre and 3% nitrogen. About 25 cocks consisting of 8 red and 17 white SB cocks selected on the basis of body weight and antibody titres were infected with 0.2 mL of 106.0 EID50 of velogenic Kudu 113 strain of Newcastle disease virus intranasaly and orally. About 25 cocks consisting of 14 red and 11 white SB cocks served as control. Cloacal temperatures, body weights and semen samples of both control and infected cocks were taken weekly for 6 weeks. The semen was evaluated for volume, colour, motility, concentration, percentage live spermatozoa and percentage total spermatozoa abnormalities. Semen colour was graded as creamy (1 = very good); milky (2 = good) and watery (3 = poor). There was no significant difference in the cloacal temperatures and body weights of control and infected red and white SB cocks. The infected red and white cocks had slightly higher cloacal temperatures than the control. The semen volume of infected red cocks showed a general increase over that of the control red cocks. The semen volume of the control white SB cocks was significantly higher than that of the infected white cocks. The white SB cocks had higher semen volume than the red SB cocks. The red SB cocks had slightly better semen colour than the white SB cocks. The control white cocks had higher spermatozoa motility than the infected white cocks while the infected red cocks had higher spermatozoa motility than the control red cocks. The white SB cocks generally had better spermatozoa motility than the red cocks. The spermatozoa concentration of the control white cocks was consistently higher than that of the infected white SB cocks; the reverse was the case with the red cocks where the spermatozoa concentration of the infected red cocks was higher than that of the control red cocks. The white cocks had better spermatozoa concentration than the red cocks. The control white SB cocks had significantly (p<0.05) higher percent live spermatozoa than the infected white cocks. Similarly, the infected red SB cocks had lower percent live spermatozoa than the control red cocks. The control white SB cocks had significantly (p<0.05) higher percent live spermatozoa than the control red SB cocks. The infected red and white SB cocks had higher percentage total spermatozoa abnormalities than the contol red and white cocks. It can be concluded from this study that the white SB cocks had better semen quality than the red SB cocks; the non-infected SB cocks had better semen quality than the infected SB cocks. It is recommended that white SB cocks be used for breeding purposes and that breeder cocks should be routinely vaccinated against Newcastle disease to ensure that the level of antibodies is high enough to prevent adverse effect on semen quality.
