(AGRICULTURAL SCIENCE AND TECHNOLOGY, 2015) Egena, S.S.A.; Tsado, D. N.; Kolo, P. S.; Banjo, A. A; Adisa-Shehu-Adisa, M
Indigenous 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.

(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

Path coefficient analysis,Red Sokoto goat, body weight, linear body measurements, indigenous goats, regression, correlation. Indigenous Red Sokoto goats raised under extensive system of management were used to evaluate the relationship between body weight (BW), head length (HL), head width (HW), height at withers (HAW), chest depth (CD), chest girth (CG), shin circumference (SC) and body length (BL). The objective of the study was to assess variability among body weight and its related characters using path coefficient analysis. Pair wise correlation between body weight and linear body measurements were positive and mostly significant (r= 0.053 - 0.826 in males; -0.020 - 0.667 in females and 0.072 – 0.690 in the combined population; P<0.05, 0.01). Path analysis showed that chest depth, shin circumference and body length made the greatest direct effect on body weight in male, female and the combined population (path coefficient = 0.360, 0.341 and 0.322, respectively) while the least direct effect was observed for height at withers, chest depth and height at withers in the male, female and the combined population (path coefficient = -0.019, -0.104 and -0.001 respectively). The optimum linear regression model with a coefficient of determination (R2 ) value of 0.684, 0.635 and 0.628 included forecast indices such as chest depth and body length in the male, head length, height at withers, chest depth, chest girth, shin circumference and body length in the female and head length, head width, chest girth, shin circumference and body length in the combined population. The optimum regression equations could be used in predicting body weight of indigenous goats in the field and for selection purposes.

(Pakistan Journal of Nutrition, Asian Network for Scientific Information, 2008) Egena, S.S.A.; Usman, Abdulkadir; Shiawoya, E.L.; Yahaya, S.K.; Ogunlowo, H.O.
One hundred and twenty day-old Hubbard broiler birds were used to study the effects of anaerobic fermentation and lyle treatment of Delonix seed meal on the performance of starter broilers. The experimental period spanned 5 weeks. The birds were divided into four treatment groups of three replicates each using complete randomized design. The anaerobically fermented and lyle treated Delonix seed meal (AFLTDSM) was used to replace groundnut cake (GNC) at 0%, 5% and 7.5% level. Untreated raw Delonix seed meal (URDSM) was also used at 5% level in order to evaluate its effects on starter broiler performance. The four treatments were designated as T1, T2, T3 and T4 respectively. Parameters evaluated were mean body weight, daily body weight gain, mean feed intake, mean feed conversion ratio as well as apparent nutrient digestibility. The results showed that mean body weight, daily body weight gain, mean feed intake and mean feed conversion ratio were not significantly affected (p>0.05) by the substitution of GNC with AFLTDSM in the diets. However, apparent nutrient digestibility of dry matter (DM), crude protein (CP), ash, ether extract (EE) and Nitrogen free extract (NFE) were significantly affected (p<0.05) by the treatment diets. Crude fibre (CF) digestibility was however not affected (p>0.05) by the inclusion of Delonix seed meal in the diets. It was concluded that AFLTDSM could be used as a substitute for GNC in starter broilers diet without any significant effect on the performance of the birds.

(Nigerian Journal of Genetics/Elsevier, 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 was carried out in the three administrative zones of Niger state, Nigeria. The animals were scored for coat colour pigmentation pattern, presence or absence 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%), but was 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%) andzone B (43.70%), respectively. It was concluded that coat colour variation exist in local goats reared extensively in Niger state
