Abstract

This study was designed to determine the physiological response of blood and immune organs ofbroiler chickens fed on various concentration of dietary black cumin powder (BCP) during the dryseason. A total number of 100 unsexed one-day old Cobb broiler chicks were used and distributed to 5treatments (control, antibiotics and without BCP, 20 g/kg BCP, 40 g/kg BCP and 60 g/kg BCP) and 4replications (5 birds for each). Physiological responses of blood and immune organs were measured at30 day of age. Addition of BCP to broiler ration did not significantly effects on physical properties ofblood (leukocytes count, erythrocytes count, haemoglobin, hematocrit, monocytes, and eosinophils) andrelative weights of thymus and bursa of fabricius, but significantly (P<0.05) increased relative weightsof spleen when compared to control. It was concluded that the black cumin grinds (Nigella sativa) as afeed additive could not change the physical properties of blood, relative weights of thymus and bursa offabricius, but it increased the relative weight of spleen at the level of 60 g/kg BCP, which could reduceadverse effects of infectious diseases in broiler chicken.

Abstract

This research aimed to study the effect of protein level and lysine supplementation on bone growth of native chicken by the age of 6 weeks. The materials used were unsexed DOC of native chicken with average body weight 25.2 ± 1.0 g. Research was carried out in 2 x 3 factorial arrangement  according to completely randomized design. There were 4 replications for each treatment combination with 10 chickens for each experimental unit. The treatments  were  P1L1 (17% protein  +  0.6% lysine of the ration ), P1L2 (17% protein + 0.7% lysine of the ration), P1L3 (17% protein + 0.8% lysine of the ration ), P2L1 (14% protein + 0.6% lysine of the ration), P2L2 (14% protein + 0.7% lysine of the ration), P2L3 (14% protein + 0.8% lysine the ration). Treatments were applied  starting from the age of  day 1 to 6 weeks of age. Parameters measured were femur length, femur weight and femur bone strength. Data were analyzed by analysis of variance followed by Duncan?s multiple range test at 5% probability level if there was a significant effect of treatment on the parameters. There was a significant interaction (P <0.05) between the level of protein and lysine supplementation affecting the femur length and femur bone weight, but there was no  interaction (P> 0.05) effects on the femur bone strength. Based on these results, it was concluded that the optimal growth of native chicken bones were obtained from the ration containing  17% protein and 0.8% lysine supplementation.
