Item Performance, blood chemistry and serum electrolytes of broilers given water from different sources(Animal Science Association of Nigeria, 2018) Adeyemo, G. O.; Kabir, A. O.; Tanimowo, D. A.; Ologhobo, A. D.The role of water sources in broiler performance was assessed using 168 Abor Acre broiler birds. The birds were randomly allotted to 4 treatments (Treatment 1(T1) - tap water, Treatment 2 (T2) – bore-hole water, Treatment 3 (T3) – well water and Treatment 4 (T4) – river water), with 6 replicates each in a completely randomized design. The initial weight was measured at hatch and subsequently on weekly basis till the final week of study. Feed intake and conversion ratio were recorded and computed, while rectal temperature was obtained using a clinical thermometer inserted into the rectum of the broiler chicken. On day 42, blood was collected via the jugular vein into sample bottles for hematological and serum electrolyte assay. Data obtained were analyzed and means separated using Duncan Multiple Range Test (DMRT). Water source was observed to significantly influence rectal temperature at the 4th week, with birds served borehole water having higher rectal temperature than birds served river water. Source of water offered to the birds was also observed to influence (p<0.05) serum levels of sodium, calcium, potassium and phosphorus. Sodium level was significantly higher in birds offered river water, while borehole water resulted in significantly higher phosphorus level in broiler chicken.Item Effect of Ad-libitum, split and restricted feeding on performance, digestibility and welfare of broiler chicken(Sciencedomain International, 2017) Adeyemo, G. O.; Badmus, R. T.; Longe, O. G.; Ologhobo, A. D.An experiment was conducted to assess the performance, welfare and digestibility of broilers fed varying forms of feeding regimes. The objective of this work research was investigate the possibility of improving growth performances, digestibility and welfare of broilers using ad libitum, split and restricted feeding. Formulated diet was given in four different forms Ad-libitum (Treatment 1) twice a day meal/split feeding (Treatment 2) thrice a day feeding (Treatment 3) 3 hours restriction feeding (Treatment 4). Experimental design was completely randomized design. 240 broilers were randomly allotted to four treatments with 6 replicates and 10 birds per replicate. Birds were weighed weekly to evaluate their performances, faeces was collected on day 42, to determine digestibility and rectal temperature was taken as a measure of bird's wellbeing. Results showed that there were no significant differences (p≥ 0.05) in performance of birds across treatments but values from birds fed Ad-libitum were higher. Rectal temperature (RT) differ at week 4, birds fed 3 hours restricted feeding had the highest RT (41.62°C) while the least RT were from birds fed Ad-libitum (41.20°C). Significant differences were obtained in digestibility and nutrient utilization of broilers with respect to feeding regimes. Crude protein (CP) digestibility was significantly higher in birds fed 3 hours restriction (81.91%) while birds fed Ad-libitum had the least (46.76%). The digestibility of crude fibre was higher in birds fed 3 hours restricted feeding regime (86.77%) the least was from birds fed thrice a day feeding regime (62.66%). A similar trend was obtained for digestibility of gross energy. Ad-libitum feeding had the highest non-significant performance values but split feeding optimized feed and nutrient utilization thereby enhancing performance and minimizing nutrient waste at the same time.
