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 PGF2α 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 PGF2α, 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 PGF2α, 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). |

The study was conducted to determine the relative resistance
of Red Sokoto and Sahelian goats to experimental infection with infective
larva (L3) of Haemonchus contortus. At the age of about 7-9 months
weaned goats were transferred to individual feeding pens and fed concentrate
at 08:00 h and given Digitaria smutsii hay ad libitum.
Fifteen goats of each breed were divided into 3 groups of five animals
each. Goats were either given 0 L3 kg-1 (treatment
1), 75 L3 kg-1 (treatment 2) or 100 L3
kg-1 (treatment 3), three times weekly for 3 weeks. The faecal
egg count expressed in Eggs per Gram (EPG) was significantly higher (p
< 0.05) for the Sahelian (1477±153.4) than the Red Sokoto
(607±147.5). The PCV didn`t show any significant difference between
breed however the difference between treatment was significant at p <
0.05. The average daily gain was higher for the Red Sokoto (11.2 g day-1)
than the Sahelian (5.6 g day-1) even though the difference
was not significant (p > 0.05). The mean total protein was statistically
different between breeds. The Red Sokoto had higher (p < 0.05) than
the Sahelian (64.6 ± 1.81 vs 57.6 ± 1.86). The mean albumin
and globulin concentration did not differ significantly between breed.
It was concluded that the Red Sokoto were relatively more resistant to
Haemonchus contortus on the basis of faecal egg count, weight gains,
changes in the PCV and total serum protein concentration. |

The milk production potentials and growth rates of Red
Sokoto and Sahelian goats fed basal diets of maize stover and Digitaria
smutsii (wolly finger grass) supplemented with concentrate was investigated
in two separate trials. In experiment 1, ten multi-parous does were allocated
to intensive management following kidding. Does were hand-milked twice
weekly and the milk production recorded. Body weight changes of dam and
kid, milk fat, milk solid were determined weekly over 12 weeks period.
The average birth weight of the Sahelian (2.2 ± 0.23 kg) was significantly
(p<0.05) higher than the Red Sokoto kids (1.0± 0.17). At weaning
age, the average kid weight of the Sahelian (5.6 ± 0.42 kg) was
significantly higher than the Red Sokoto (3.9 ± 0.44 kg). There
was no significant difference (p>0.05) in daily milk yield and total
lactation between the two breeds. The total solids and milk fat of 16.4
± 0.39 and 3.7 ± 0.13% were significantly (p<0.05) higher
for the Red Sokoto than the Sahelian (15.1 ± 0.39 and 3.2 ± 0.13%).
The second trial was to evaluate the comparative growth of the Sahelian
and Red Sokoto breeds of goats. Animals were group-fed based on sex and
fed Digitaria smutsii hay supplemented with concentrate. The growth
trial lasted for 150 days with a 14 day digestibility trial. The Average
Daily Gain (ADG) were significantly (p<0.05) different for breed, as
well as sex. The Red Sokoto (66.9 ±1.59) kids had higher ADG than
the Sahelian (46.6 ±1.59). Similarly the males of the Red Sokoto
(61.9 ±1.59) had higher ADG than the Sahelian males (46.7 ±0.59)
and the females of both breed. The experiments demonstrated a linear increase
in weight gains of Red Sokoto over the Sahelian and a slightly higher
milk yield obtained from the Sahelian providing the basis to conclude
that the Sahelian goat can adapted and fit into the production systems
of Sudan Savannah rural farmers. |
