Item Response of broiler chickens to carica papaya and talinium triangulare leaf meal under normal and subnormal diets(Sciencedomain International, 2018) Agboola, B. E.; Ologhobo, A. D.; Adejumo, I. O.; Adeyemo, G. O.The use of locally available and cheap feed ingredients has received particular attention as a viable alternative to the use of conventional feedstuffs in developing countries. Vegetable-based feeds are rich sources of essential plant amino acids, vitamins, minerals, and antioxidants. Further to the rich contents mentioned, it has been established that green vegetable leaves are cheap and abundant sources of protein because of their ability to synthesize amino acids from a wide range of available primary materials. The aim of this study was to investigate the response of broiler chickens to Carica papaya and Talinium triangulare under normal and subnormal diets. In this study, the effects of C. papayaleaf meal and T. triangulare chopped leaves were assessed on growth performance and haematological parameters of broiler chickens. Two hundred and seventy 1-d old Arbor acres broiler chicks were used for the study. Each treatment had 5.replicates with 6 birds per replicate. Normal diets and subnormal diets were compounded with varying amounts of ingredients. The test ingredients were supplied at the rate of 10% of the main diets. The design of the experiment was a completely randomized design. All the treatments with subnormal diets obtained higher feed intake than treatments with normal diets. Birds on subnormal diet mixed with C. papaya leaf meal (24.03%) obtained the highest packed cell volume. The haemoglobin concentrations followed a similar pattern. Normal diets compared with control for feed conversion ratio.Item Effect of water electrolyte supplementation on perfonnance, serum and haematological indices of broiler chickens under heat-stressed condition(Animal Science Association of Nigeria, 2018) Adeyemo, G. O.; Sulaiman, A. K.; Tanimowo, D. A.; Longe, O. G.In a study to assess the effect of electrolyte supplementation on performance of broiler chicken, 192 day- old Abor Acre broiler chicks were randomly allotted to 4 treatments: T1 - un-supplemented water, T2 - 0.5% NaCI, T3 - 0.5% KCI and T4 - 0.5% NaHCO3, with 6 replicates each in a completely randomized design. Initial weight, final weight, weight gain, feed intake were recorded and feed conversion computed. Mortality was recorded when observed. Ambient temperature and relative humidity were monitored daily. At the end of day 28, rectal temperature of each bird was recorded weekly for 3 weeks using a digital thermometer. At day 42, blood (5mls) was collected for haematological indices and plasma separated for the determination of Cl, Na, K, Ca, P, Mg, HCO3. Data obtained were analyzed and means separation determined by least significant differences (p<0.05) using the SAS Institute statistical software. Under heat stress, 0.5% KCI and 0.5%NaCI supplementation in water reduced rectal temperature, increased body weight, improved FCR, and reduced blood pH. Electrolyte supplementation also influenced red blood cell count as well as serum levels of sodium, potassium and bicarbonate. Supplementing KCI and NaCI in drinking water may be a means to improve productivity of broiler under high temperature and humidity conditions.Item Performance and tibia characteristics of chickens fed cassava chips supplemented with Dl-methionine(Sciencedomain International, 2016) Ologhobo, A. D.; Etop, S.; Ogunwole, O. A.; Adeyemo, G. O.; Adejumo, I. O.; Adeoye, D.This study was carried out to investigate the effect of cassava chips and DL-methionine supplementation on performance and tibia bone characteristics of broiler chickens. Broiler chickens were randomly assigned to 20 treatments in a 4x5 factorial arrangement with 5 dietary levels of cassava chips (0, 25, 50, 75 and 100 corn replacement) and 4 dietary levels of DL-methionine supplementation (0, 0.05, 0.1 and 0.2% i.e. 0, ½ NRC, NRC and double NRC 1994 recommended levels). Data obtained were subjected to analysis of variance. At starter phase, birds on cassava chips-based diets had significantly (P<0.05) higher body weight gain (BWG) than the control. Those on 25% cassava chip-based diet compared well with the control. Methionine supplement improved BWG at both starter and finisher phases; Cassava chips supplemented with DL-methionine can replace corn 100.00% in broiler chickens diet.Item Dietary effect of different drying methods and graded inclusion levels of ginger (zingiber officinale) on the perfonnance and gut morphology of broilers(Sciencedomain International, 2016) Adeyemo, G. O.; Ogunshote, E. O.; Longe, O. G.The experimental design was a 3 by 3 factorial arrangement in a completely randomized design. Three hundred broilers were used for the experiment; they were randomly allotted to the ten dietary treatments with 5 replicates per treatment and 6 birds per replicate. The birds were weighed weekly to determine their weight gain, body weight and feed conversion ratio. Thirty finisher birds were sacrificed and the ileum and duodenum removed for gut histo-morphometry. Results showed that drying methods influenced performance. This was observed for the average body weight gained per bird per day while the effect of the inclusion level was observed on the feed conversion ratio. Factor interaction was observed for weight gained/bird per day and feed conversion ratio. However, only numerical differences were observed for average final body weight/bird and average feed intake /bird/day. Duodenal and ilea, villous height showed significant effect (P<0.05) of drying method, inclusion levels and treatment interaction with the control having the highest mean values. It can be concluded that supplementing broiler feed with air-dried ginger at 1.5% inclusion level can be effective as it led to an increase in the final body weight, average body weight gained per day per bird and average feed intake. No effect of drying methods and inclusion levels were observed for the histo-morphometry.Item Effect of dietary inclusion of ginger (zingiber officinale) dried with different methods on perfonnance and gut microbial population of broiler chicks(Sciencedomain International, 2016) Adeyemo, G. O.; Olowookere, I. J.; Longe, O. G.Effect of dietary inclusion of differently processed ginger on performance and microbial population of broiler chicks were investigated in a 52-days feeding trial. A total of three hundred one-day old (arbor acre) broiler chicks were used for the experiment, the birds were allotted into ten dietary treatments of five replicates and six birds per replicate in a 3x3 factorial arrangement of completely randomized design. Weights of the birds were taken weekly throughout the experimental period. Birds were fed ad-libitum such that diet 1 was the basal diet (BD) without ginger, diets 2, 3 and 4 were BD+ sundried ginger at 1, 1.5, 2% inclusion levels respectively, diets 5, 6 and 7 were BD+ air- dried ginger at 1, 1.5 and 2% inclusion levels respectively, diets 8, 9 and 10 were BD+ oven-dried ginger at 1, 1.5 and 2% inclusion level respectively. On day 52 of the experiment, the birds were slaughtered. Sections of the ileum was cut and aseptically emptied into a sterile bottle for microbial analysis. Broilers fed diets containing ginger had no significant (P> 0.05) differences on the average initial body weight, average final body weight and average daily feed intake. Although the birds fed with diet containing oven-dried ginger at 2% inclusion level had the least (P>0.05) numerical difference of the average daily feed intake. The average body weight gain and feed conversion ratio (FCR) were not significant across the dietary treatments. Birds fed diet without ginger had higher body weight gain and best feed conversion ratio (P<0.05). The total Aerobic and coliform microbial counts of broilers were not significantly (P>0.05) affected by the dietary treatments. Although the total aerobic microbial count was reduced in birds fed diets containing ginger when compared with the control.Item Performance and egg quality traits of egg-type chickens fed cottonseed cake based diets(Department of Agricultural Extension and Rural Development, University of Ibadan, 2015-07) Adeyemo, G. O.The study evaluated the performance of egg type chickens fed diets where Cottonseed cake (CSC) replaced Soybean cake (SBC) in five experimental rations such that 0% (control), 15%, 30%, 45% and 60% of CSC replaced SBC. The design of the experiment was completely randomized design (CRD). Chemical analysis was carried out to determine the crude protein (CP) and gossypol contents of CSC. Seventy-five 23 week - old egg type chicken were fed with experimental layer diets for 12 weeks. Parameters evaluated include hen-day production (HDP), Feed conversion ratio (FCR), egg weight (EW) and haugh units (HU). All data were analyzed using descriptive statistics and analysis of variance. The determined CP of CSC was 35.11% and its gossypol content was 570g/ton. FCR ranged from 1.6 to 4.9, HDP from 47% to 68%, EW from 47.5 to 62.8 g, and HU from 3.1 to 6.7. Chickens on 60% CSC replacement for SBC had higher values for the parameters measured which were not significantly different from the control. CSC can replace up to 60% SBC without adverse effects on performance and egg quality characteristics of egg type birds.Item Effects of stocking density and season on growth performance and welfare of broiler chickens in Ibadan, Nigeria(2017) Ademulegun, T. I..; Adeyemo, G. O.; Salako, A. E.The study was carried out to investigate the effects of season and stocking density on the growth performance and welfare of broiler chickens in Ibadan, Nigeria. In a seven-week feeding trial, a total of 96 one-week old Arbor Acre broiler chickens were randomly distributed to three stocking densities (birds/m2) of 10, 12, and 14 at the rate of 32 birds per stocking density (SD) during each season; Late Wet (LWS) and Late Dry (LDS). Total Feed Intake (TFI, g), Final Live Weight (FLW, g), Feed Conversion Rate (FCR), Live weight/m2(LW/m2), Normal Gait Score(NGS,%), Survival Rate(SR %), Heterophil: Lymphocyte(H:L) ratio, were assessed. Data were subjected to statistics analysis (ANOVA at α0.05). Birds raised during LWS had higher TFI (4756.60) than LDS birds, while SD had no effect on TFI. Birds on SD of 14 birds/m2 had lower FLW. The FCR was lower during LDS and on SD 10 and 12 Birds/m2. The LW/m2 was higher in birds on SD 14birds/m2. The LWS had higher NGS and lower H:L ratio. Season and SD had no effect on SR. The NGS and H:L were not affected by SD. Broiler chickens could be raised at stocking density of 14birds/m2 during either of the seasons.
