Item Carcass yield, organoleptic and serum biochemistry of broiler chickens fed activated charcoal(Scienceweb Publishing, 2014-05) Jiya, E. Z; Ayanwale, B. A; Adeoye, A. B.; Kolo, P. S.; Tsado, D. N.; Alabi, O. J.Two hundred and twenty five (225) unsexed Marshal Broiler chicks were used to investigate the carcass yield, organoleptic and serum biochemistry of broilers fed activated charcoal. The broiler chicks were randomly allotted to five dietary treatments, supplemented with activated charcoal at 0, 0.5, 1, 1.5 and 2% and designated as T1, T2, T3, T4 and T5, respectively. Each treatment was grouped in three replicate with 15 birds per replicate. At the end of 8 weeks experimental period, a total of 15 broiler chickens were used for both carcass and blood analysis with three birds per treatment. Data was collected on carcass characteristics, sensory evaluation, and blood serum cholesterol. There were significant (P < 0.05) differences in the values of dressed weight, eviscerated weight, gizzard, abdominal fat, heart and spleen, while other carcass parameters were not significantly (P > 0.05) different. The result of the sensory evaluation were significant in all the parameters measured, while the serum biochemical analysis showed that SGOT (serum glutamine oxaloacetic transminase, SGPT (serum glutamine phosphates transminase), albumin, cholesterol and triglycerides were significantly (P < 0.05) different except alkaline phosphates and SGPT that were not significantly different. However, activated charcoal would serve as a good source of growth promoter for broiler birds to improve feed efficiency and their health. It is therefore concluded that at 0.5% activated charcoal supplementation increased relative organ weights, reduced cholesterol level of the broiler meat as a result or efficient mineral intake and nutrient utilization due to the absorptive effect of the activated charcoal.Item Path coefficient analysis of body weight and body measurements in Red Sokoto goats (Caprahircus l.) of Niger State, Nigeria(Revue Agriculture, 2014-06) Egena, S.S.A; Tsado, D.N.; Kolo, P. S; Banjo, A. A; Shehu-Adisa, M.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.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, 2015-06-05) Egena, S. S. A; Tsado, D. N; Kolo, P. S; Banjo, A.A; 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 2 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.Item Growth Performance and nutrient digestibility of broiler chickens fed diets containing varying inclusion levels of dried watermelon rind at the starter phase.(Nigerian Journal of Animal Production, 2021) Otu, B. O.; Banjo, A. A.; Kolo, P. S.; Balogun, A. M.; Dabban, A. I.Watermelon rind is one of the several unwanted by-products generated by restaurants, fruit juice producers and food industries in Nigeria that can be gotten rid of by using it as an energy source in broiler production. The growth performance and apparent nutrient digestibility of broilers fed diets containing varying inclusion levels of dried watermelon rind (DWMR) in replacement for wheat offal as source of energy and fibre at starter phase was evaluated. The dried watermelon rind was prepared by sun-drying fresh watermelon for three days and oven-dried at 50 ºC for 2 hours. The birds were randomly allocated to five (5) treatments (T – T ), each treatment had three replicates with ten (10) birds per replicate. The 1 5birds were fed varied levels of DWMR at 0 %, 25 %, 50 %, 75 % and 100 % in replacement of wheat offal to obtain five diets. Feed and water were provided ad-libitum throughout the 28 days study duration. Body weight, Body weight gain, Feed intake, Feed conversion ratio and apparent nutrient digestibility were measured. The results obtained on the growth performance shows no significant (P>0.05) difference of the growth parameters across treatments. However, there was significant (P<0.05) difference in the digestibility of Crude fibre, Ether extract, Ash, Nitrogen free extract and Total digestible nutrient across treatments. There was no obvious variation in dry matter and crude protein digestibility. The result of the total digestible nutrient was significantly (P<0.05) higher in T (92.90 %) than 2 the T (84.99 %) which was the control diet. The crude fibre digestibility recorded in T (63.48 1 2%) and T (61.09 %) is higher than T (43.00 %), the ether extract digestibility of T (96.42 %) 1 5 1is higher than the other groups with the lowest in T (95.25 %). There was depress ash 4 digestibility in T (68.30 %), lower than the other groups with the highest in T (82.59 %). The 5 1study therefore concluded that farmers can replace wheat offal with 25 % watermelon rind in broiler starter diet without any deleterious effect in the growth performance and nutrient digestibility.Item A study on haematology and serum biochemistry of wattle and non wattled red sokoto does and their offspring(Nigerian Journal of Animal Production., 2021) Kolo, P. S.; Otu, B. O.; Banjo, A. A.; Kolo, H. N.A study on haematology and serum biochemistry of wattled and non wattled Red Sokoto does and their offspring *Kolo, P. S., Otu, B., Banjo, A. A., and Kolo, H. N. Department of Animal Production, Federal University of Technology, Minna, Niger State, Nigeria. Corresponding author: kolo.philip@futminna.edu.ng; +2347035071871 Wattle is of utmost ornamental importance for courting potential mates and influencing thermoregulatory mechanisms which help the animal adapt to the environment. It also provides information on relationship between haematological and serum biochemical parameters. A study on haematology and serum biochemistry of wattled and non wattled Red Sokoto does and their offspring was carried out at the Teaching and Research Farm of the Department of Animal Production, Federal University of Technology, Minna. Fifty (52) Red Sokoto goats comprising of thirty-two (32) does four (4) bucks and sixteen (16) weaned kids managed semi-intensively were used for the study Blood samples were collected using 5 ml syringe and 22-guage needle from the jugular vein. 5 ml of blood was collected from each goat used out of which 2.5 ml was dispensed into Ethylene Diamine Tetra Acetic Acid (EDTA) bottle while the remaining 2.5 ml was dispensed into plain (anticoagulant free) bottles and labelled properly according to the treatment group. Data collected were analyzed using SAS statistical package. It was observed: that wattle had significant effect (p<0.05) on Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC), White Blood Cell (WBC), Sodium, Potassium, Calcium, Chloride, Phosphorus, Cholesterol, Total Protein, Low Density Lipoprotein (LDL) and Total Bilirubin of Red Sokoto Does but had no significant influence on the haematology and serum biochemistry of wean Red Sokoto kids. Does in T had the highest MCH values of 63.50 mmo/l while treatments T1 3 , T2 and T4 had values of 23.00 mmo/l, 33.00mmo/l and 34.00mmo/l respectively. Also Does in T2, T3 and T4 recorded higher calcium levels of 2.54mmo/l, 2.56mmol/l and 2.61mmo/l) respectively compared to values of 2.29mmo/l recorded in T1. These relevant influence of wattle therefore should suggest the deployment of deliberate effort to preserve the wattle gene to prevent the goats carrying the gene from going to extinction.Item Growth performance and nutrient metabolizability of Japanese Quails (Coturnix coturnix japonica) orally administered varying levels of Lemon grass (Cymbopogon citratus, Stapf) aqueous extract(Indian Journal of Poultry Science, 2022-08-31) BANJO, A.A.; ALABI, J.O.; OTU, B.O.; KOLO, S.P.; OMOTOLA, MA 42-days trial was conducted to evaluate the efficacy of lemon grass aqueous extract (LGAE) on growth performance and nutrient metabolizability of Japanese quails (Coturnix coturnix japonica). The 10 days old Japanese quails (n = 240) used in this study were allotted to 5 groups and were fed a common corn-soybean meal-basal diet unrestrictedly for a period of 42 days. The five treatments include the control group fed basal diet with no additive, the second group received antibiotics (Embacox® at 8g per litre) while the remaining three (3) treatments were administered LGAE in drinking water at varying levels of 0.20, 0.40, and 0.60 ml per litre once a week. The quails which received 0.2ml LGAE per litre had higher (P<0.05) body weight gain, and daily feed intake was increased by 3.88% when compared with antibiotic-treated group. FCR was higher (P<0.05) in quails exposed to 0.4 and 0.6ml LGAE while the least value was obtained in quails which received antibiotics (Embacox®). Significant increase in water intake (P<0.05) and water to feed ratio (P<0.001) was observed in growing quails which received 0.2ml LGAE when compared to other treatments. Japanese quails which received lemon grass extract in water showed higher (P<0.05) nutrient metabolizability, except crude fibre, than those in control group. Nutrient metabolizability increases (except for fibre) as the LGAE inclusion level increases. The study concluded that Japanese quail served 0.2ml LGAE per litre had similar growth rate with those on control groups while additional dosage resulted in negative effects. LGAE administered in drinking water up to 0.6ml per litre enhance nutrient metabolizability and utilizationItem Influence of wattle on udder measurements and milk yield of Red Sokoto (Maradi) does raised semi-intensively in Minna, Niger state, Nigeria.(Nigerian Journal Animal Science, 2023) Kolo, P. S.; Alemede, I. C.; Egena, S. S. A.; Adama, J. Y.; Banjo, A. A.; Otu, B. O.; Abubakar, M. B.; Agboba, K.; Maidariya, H, A.; Omolade, C.; Okike, C.; Idajili, G.; Yusuf, A.; Apata, A. M.A study on the Influence of wattle in Red Sokoto (Maradi) goats on udder measurements, colostrum/milk quantity and quality was carried out at the Teaching and Research Farm of the Department of Animal Production, Federal University of Technology, Minna. Thirty-six (36) Red Sokoto goats comprising of thirty-two (32) does and four (4) bucks, managed semi-intensively, were used for the study. Parameters observed included udder circumference, distance between teats, change in udder circumference, change in distance between teats, teat length after milking, milk quantity and quality analysis. After the experiment, it was observed that crosses between the wattle and the nonwattled had the highest (p<0.05) udder circumference before and after milking, quantity of milk and average daily milking. Wattled does crossed with non-wattled bucks in T3 and Wattled does crossed with wattled bucks in T4) produced the highest (p<0.05) peak yield. Wattled does mated with wattled bucks (T4) had the highest (p<0.05) total milk yield. Wattled does mated with wattled bucks (T4) had the (p<0.05) highest moisture content in colostrum sample which reduced the availability of other minerals. Non-wattled does mated with non-wattled bucks (T1) and wattled does mated with wattled bucks (T4) had the highest (p<0.05) moisture content in the milk sample which reduced the availability of most minerals in the milk. In conclusion, attention should be focused on the crosses between the wattled and the non-wattled Red Sokoto as it gave best result in most parameters examined. Deliberate effort must be made to preserve the wattle gene to prevent the goats carrying the gene from going into extinction.Item Effect of spice-treated sundried bovine rumen digesta on performance, carcass characteristics and nutrient digestibility of finisher broiler chickens(Journal of Animal Science and Veterinary Medicine, 2023-04-12) Eniwaiye, A. A.; Otu, B. O.; Kolo, P. S.; Owolabi, S. J.; Balogun, M. A.; Ochiyan, M. A.The study was conducted to investigate the effects of feeding diets containing spice treated Sundried Bovine Rumen Digesta (SDBRD) on growth performance, carcass characteristics and nutrient digestibility of broiler chickens. A total of one hundred and fifty (150) day old broiler chickens were assigned to five (5) diets in triplicates containing ten (10) birds each in a completely randomized design. The diets were; T1, (control, 0% SDBRD), T2 (20% SDBRD without spice supplementation), T3 (20% SDBRD + 200 mg ginger), T4 (20% SDBRD + 200 mg garlic), and T5 (20% SDBRD + 200 mg thyme). Data were collected on growth performance, carcass characteristics and nutrient digestibility. The data were analysed using the Analysis of Variance (ANOVA) and differences among mean were separated with the Duncan Multiple range. The results showed that broiler chickens fed diets containing spices-supplemented SDBRD had significantly (p<0.05) higher weight gain and better feed conversion ratio (FCR). The live weight and dressing percentage were significantly (p<0.05) higher among birds fed spice-supplemented diets compared to the control and the un-supplemented SDBRD diet. However, digestibility for dry matter and crude protein was higher (p<0.05) on T1 and T2 than on spicesupplemented diets. It was concluded that the combination of sundried bovine rumen digesta and spices such as garlic, ginger and thyme improve growth performance, carcass characteristics and nutrient digestibility, and can therefore be included in the ratio of broiler finisher at 20% level without any deleterious effect.
