Item Influence of wattle on body measurements, scrotal and semen of red Sokoto bucks kept semi-intensively in Niger state, Nigeria.(Lapai Journal of Science and Technology, 2019) Kolo, P. S.; Alemede, I. C.; Egena, S. S. A; Adama, J. Y.SelfItem Effect of sex, wattle, beard, hair type, and extra teat on growth-related traits of extensively managed goat (Capra aegagrus) population of Niger State, Nigeria.(Equity Journal of Science and Technology, 2016) Kolo, P. S.; Egena, S. S. A.; Tsado, D. N.; Adisa-Shehu, MAstudy that evaluated the effect of sex, wattle, beard, hair type and extra teat on growth traits of goats extensively managed in the three Senatorial zones ( i.e zones A, B and C) of Niger state was carried out. The growth traits evaluated include body weight, body length, height-at-withers, chest depth, chest girth, head length, head width, rump length, rump width, shin circumference, fore leg length and hind leg length.Male goats had better (p<0.05) measurement in all parameters considered in zone B of the state while the females were better (p<0.05) in all parameters measured in zones A and C except for shin circumference in which the males were better in zone A. Goats without wattle showed superiority (p<0.05) in most of the parameters measured in zone C. This was not so for goats in zones A and B as there was no clear demarcation between goats with or without wattle. Goats with beard were superior (p<0.05) in most of the parameters measured in zones B and C. Coarse hair type had significant (p<0.05) effect on body weight and all the other body measurements except for height-at-withers which was not significantly (p>0.05)affected. Soft hair had significant (p<0.05) effect on body weight, and all the body measurements except for hind leg length which showed no significant (p>0.05) difference. Extra teat had no significant (p>0.05) effect on body weight, body length height-at-withers, chest depth, chest girth, head length, rump width, shin circumference and hind leg length but significantly (p<0.05) influenced head width, rump length and fore leg length. Absence of extra teat had significant (p<0.05) effect on all the parameters measured except for head length which showed no significant (p>0.05) difference. At the end of the study, it was observed that sex and major genes had significant effect on most of the parameters measured. It is recommended based on the result emanating from the study that farmers be encouraged to rear goats with beard, those without extra teat and wattle since they were better in most of the parameters measured.Item Performance and haematological profile of broiler starter birds fed graded levels of raw Allamanda cathartica (L) seed Meal diet.(Journal of Agriculture, 2012) Malik, A. A.; , Aremu. A; . Adelowo, A.; Kolo, P. S.; Haruna, B. G.The response of 120 day-old broiler starter birds to graded dietary inclusion levels of 0.0 %, 2.5 %, 5.0 %, 7.5 % and 10.0 % of raw Allamanda cathartica (L) seed meal (ACSM) to form diets 1, 2, 3, 4 and 5 respectively was investigated. The isocaloric and isonitrogenous diets were fed to the birds for 4 weeks, after which a digestibility trial was carried out. Blood samples were collected for haematological and biochemical analyses at the end of the second week. Feed intake/bird/week and weight gain/bird/week decreased progressively as the dietary inclusion level of ACSM increased (280.52g/209.34g, 160.20g/99.50g, 90.41g/53.18g, 70.10g/38.73g and 41.30g/21.51g for diets 1, 2, 3, 4 and 5 respectively); while feed conversion ratio increased progressively (p<0.05) as the dietaryACSM level increased (1.34, 1.61, 1.70, 1.81 and 1.92 for diets 1, 2, 3, 4 and 5 respectively). No mortality was recorded for the control diet (with 0 % dietary inclusion level of ACSM), while mortality increased progressively asthe dietary ACSM level increased (p<0.05), reaching up to 100 % at 10 % inclusion level. Dietary treatments had no effect on ether extract digestibility but birds on 0 % and 5 % ACSM diet significantly digested crude protein and crude fibre better than the 2.5 % ACSM diet. No significant (p>0.05) effect was observed on all the haematological and biochemical parameters investigated for the five dietary treatments. It is therefore concluded that ACSM contains potent anti-nutritional factors which are extremely toxic to broiler starter birds at whatever dietary inclusion level. So, there is the greatest need to detoxify the raw seed meal before it can be effectively incorporated into broiler starter diets.Item Phenotypic and genetic categorization of qualitative traits in extensively managed local goat (Capra aegagrus) population of Niger State, Nigeria(Nigerian Journal of Genetics, 2015-10-09) Kolo, P. S.; Egena, S.S.A.; Tsado, D.N.; Adisa-Shehu, M.A study on the distribution and frequencies of coat colour, wattle, beard, horn, and hair type using 375 extensively managed local goats wascarried out in the three administrative zones of Niger state, Nigeria. The animals were scored for coat colour pigmentation pattern, presence orabsence of wattle, beard, horn, hair type and extra teat. The study showed that light brown is the predominant colour in zones A (43.24%) and zone C (47.57%). Dark brown colour was predominant in zone B (37.82%) followed by light brown (31.09%). The observed frequencies for wattle (Waw) and extra teat (Ete) were above (p < 0.01) the expected Mendelian value of 75% for a dominant gene in all the zones (90.34, 86.55, 87.39 percent for wattle and 91.73, 96.64, 98.21, percent for extra teat in zones A, B, and C, respectively). The gene frequency for beard (Brb) were significantly lower (p < 0.01) than the expected Mendelian value of 75% for a dominant gene in zone A (66.20%) and zone B (55.46%), butwas higher in zone C (83.78%). The gene frequency for polledness (Pop) was 0.00% for all the zones. The gene frequency for soft hair.was more than (p < 0.01) the expected Mendelian value of 75% for dominant genes in zone C (87.33%) but fell short in zone A (60.69%) and zone B (43.70%), respectively. It was concluded that coat colour variation exist in local goats reared extensively in Niger state.Item Application of path coefficient analysis in assessing the relationship between growth-related traits in indigenous Nigerian sheep (Ovis aries) of Niger State, Nigeria(AGRICULTURAL SCIENCE AND TECHNOLOGY, 2015) Egena, S.S.A.; Tsado, D. N.; Kolo, P. S.; Banjo, A. A; Adisa-Shehu-Adisa, MIndigenous Nigerian sheep raised under extensive management were evaluated with the aim of assessing variability among body weight and body measurement traits thereby deducing components that best describe the relationship using path coefficient analysis. The parameters measured were body weight (BW), body length (BL), head length (HL), head width (HW), height at withers (HAW), chest depth (CD), chest girth (CG) and shin circumference (SC). Pair wise correlation between body weight and body measurements were positive and significant (r = 0.475 – 0.655 in males, 0.262 – 0.449 in females, and 0.336 – 0.509 in the combined population, P<0.01). Path analysis showed that shin circumference and chest depth had the greatest direct effect on body weight in male, female and the combined population (path coefficient = 0.250, 0.252 and 0.250, respectively) while the least direct effect was observed for head width (in male and female with path coefficient = 0.007 and -0.017, respectively), and height at withers in the combined population (path coefficient = -0.020). Percentage direct contribution to body weight was 6.25, 6.35 and 6.25% from shin circumference (male), chest depth (in female and the combined population respectively). The optimum linear regression models with coefficient of determination (R ) value of 0.45, 0.31 and 0.37 included forecast indices such as chest depth and shin circumference in males, body length, head length and chest depth in females and the combined population, respectively.
