| This experiment was conducted in poultry fields of the Department of Animal Production - College of Agriculture -University of Kirkuk for the period from 20/3/2021 to 1/5/2021 for a period of 42 days. The aim of this study was to determine the effect of Betaine and Taurine with the herbal methionine upon the productive performance, carcass characteristics for broiler ROSS 308. In this study we used 350 chicks of broiler ROSS 308 unsexed, at the age of one day, the weight rate was 42 gm per chicken, Chickens were distributed from the first day to 7 feeding treatments, (50 birds/ treatment) with 5 replications/ treatment. ( 10 birds/replicate), and each replicate included 10 birds in 35 cages by dimensions (90×190cm). The birds of experiment were fed with the following nutritional Treatments: The first treatment: (control)without any addition, the second treatment: (control) positive adding the Indian herbal methionine to meet the needs. The third treatment is Betaine instead of the herbal methionine to fill the body's need of methionine, and the fourth treatment is the replacement taurine instead of the herbal methionine to fill the body's need of methionine, and the Fifth transaction Add the Betaine compound by 50% and taurine by 50% of the body's need for the herbal methionine to fill the needs, and the sixth treatment is (Control) Addition of Betaine at 25% and Taurine at 75% instead of herbal methionine to meet the bird's methionine needs , and the sixth treatment (Control): Addition of Betaine at 75% and Taurine at 25% instead of herbal methionine to meet the bird's needs of methionine. The results of the statistical analysis showed that there were significant differences (P≤0.05) in the rate of weight gain, we note that T6 was significantly (P≤0.05) superior to T3, T4 and T5, and in the rate of feed consumption, we noticed a significant decrease in the total feed consumption for all treatments added to the two compounds betaine and taurine and herbal methionine compared with the control group, as for the characteristic of the rate of food conversion factor, we notice a significant improvement for all treatments added to it the two compounds betaine and taurine compared with the control group, and in the character of the relative weight of the internal organs eaten, it is noted that T1 was significantly (P≤0.05) superior to T2. In the mean relative weight of the heart, liver, gizzard and abdominal fat. As for the carcass cuts, it was found that T3, T4, T5, T6 and T7 were significantly superior to the T2 in the average netting ratio, in the relative weight of the chest, a significant (P≤0.05) was found for T5 and T7 over T3 . T7 significantly (P≤0.05) over the rest of the treatments, and in the weight of the drumstick, a significant increase was observed in favor of T7 over T1 and T4. As for the relative weight of the back, T3 significantly (P≤0.05) exceed T4, and it was noted in the relative weight for wings, T1 exceed T2, and the T1 (P≤0.05) was significantly superior to T3 and T4 in neck weight | ||
