    Effect of Breed and Sex on Pelt Growth of New Zealand White and Chinchilla Gigantas Rabbits.
    (International Conference of Agriculture and Agricultural Technology, 2022-12-12) Eniwaiye, A. A.; Otu, B. O.; Kolo, S. P.; Owolabi, S. J.
    New Zealand White and Chinchilla Giganta rabbits are breeds of rabbits popularly known for their meat production and pet strain and usually produce top quality pelts when slaughtered. As the rabbits increased in sizes, so also are the pelt weight and pelt area which corresponded to the body volume and the vastness of the pelt. The research aim was to study the effect of breeds and sexes on the development of pelt. A total of 216 (54 males and 54 females of NZW; 54 males and 54 females of the Chinchilla Giganta) rabbits were used in this research. Data were analysed with analysis of variance using GenStat software and the pelt area was calculated using ImageJ analysis. Variables observed were pelt weights and pelt area. The results showed that sexes had no interaction on pelt area but the breed does, and as the rabbit’s increases in age, so also the increase in pelt weight and pelt area

    Semen Characteristics Of Rabbit Bucks Fed Graded Levels Of Newbouldia Laevis Leaf Meal.
    (International Conference of Agriculture and Agricultural Technology, 2022-12-12) Kolo, H. N.; Abdulraheem, B. O.; Otu, B. O.; Kolo, P. S.; Banjo, A. A.; Dikko, A. H.
    This study evaluated the effect of Newbouldia laevis leaf meal on the semen characteristics of Rabbit bucks. Twenty four rabbit bucks of 5-6 months old weighing 1.44 kg – 1.96 kg were acclimatized and allotted randomly into four treatments: T1 (control), T2, T3 and T4. The crude protein was set at 16% with inclusion levels of 0 %, 2.5 %, 5 % and 7.5 % Newbouldia laevis leaf meal respectively for12 weeks. Semen samples were collected and evaluated fortnightly for semen volume, semen motility and semen concentration. The mean values of semen volume and semen motility of rabbit bucks was not significantly (p>0.05) different across all the groups. The mean values for semen concentration of T4 was significantly (p<0.05) different from the controls. It was concluded that Newbouldia laevis leaf meal improved the testicular functions of rabbit buck.

    Growth And Body Morphometric Parameters Of Broiler Chickens Orally Administered Varying Levels Of Lemongrass Extract, At Finisher Phase.
    (International Conference of Agriculture and Agricultural Technology,, 2022-12) Otu, B. O.; Banjo, A. A.; Kolo, P. S.; Egena, S.S.A.; Dikko, A. H; Audu, F.
    The growth and body morphometric parameters of broiler chickens orally administered varying levels of lemongrass extract at finisher phase was evaluated. A total of 150-day old broiler chicks were used for this study in a CRD design. The birds were allotted into five treatments of 30 chicks in each treatment with three replications of 10 chicks per replicate. The control (T1) group was not administered antibiotic nor lemongrass extract and treatment group T2 was administered 0.2mls of antibiotic while T3, T4 and T5 treatment groups were administered 0.2mls, 0.4mls and 0.6mls of lemongrass extract respectively. Data on the growth and morphometric parameters were collected. There was no significant difference (P>0.05) in the growth parameters with an exception of the average initial body weight. The average final body weight (g) in T1, T2, T3, T4 and T5 were 1781.48, 1767.59, 2061.90, 1897.62 and 1898.31 respectively. The average body weight of broiler birds in T3 was higher as compared to those in T1, T2, T4 and T5. The body weight gain in T1, T2, T3, T4 and T5 were 1249.78, 1266.22, 1458.24, 1386.54, and 1420.91 respectively. The birds in treatment groups T3, T4 and T5 recorded higher weight gain than T1 (control group) and T2 (0.2mls antibiotic). The feed intake (g) were 359.87, 3152.33, 4039.16, 3777.33, 4063.40 in treatment T1, T2, T3, T4 and T5 respectively. The treatment group T5 consumed more feed (4063.40g) compared to the other treatments. Feed conversion ratio was higher in T5 (2.82) as compared to T1 (2.81), T2 (2.49), T3 (2.77) and T4 (2.73). However, there were significant (P<0.05) differences in average initial body width, final body girth, final shank length and shank length gain compare to other parameters such as initial body length, final body length, body length gain, body width gain, final body width, initialshank length, initial neck length, final neck length, which were not significantly affected. It can be concluded that the use of lemongrass extract at the levels 0.6mls and 0.2mls proved to have improved the growth performance as well as better performance of the morphometric parameters
