摘要

Abstract This experiment was conducted in the poultry hall of the Department of Animal Production Technologies, Al-Musayyib Technical College, Al-Furat Al-Awsat Technical University for the period from 9/17/2023 until 10/22/2023 to study the effect of using different levels of red Chili pepper Capsicum annuum and the essential amino acid synthetic methionine DL- Methionine in some productive traits of broilers. The research used 525 Ross 308 broiler chicks, one day old and with a starting weight of 43 grams, which lasted for five weeks. The chicks were distributed randomly and equally into seven treatments. Each treatment included 75 chicks, with three replicates (25 chicks/replicate). The chicks in this experiment were fed two diets, the first the starter diet from the age of 1-21 days, while the chicks were fed the finisher diet from the age of 22-35 days (the end of the experiment). The treatments were distributed as follows: the first treatment, T1, fed the chicks on a basic diet (control treatment). The second treatment, T2, was fed on a basic diet with red chili powder added at an average of (0.50 g/kg feed). In the third treatment, T3, the chicks were fed a basic ration with red chili powder added at an average of (0.75 gm/kg feed), the fourth treatment T4 chicks were fed a ration with red chili powder added at an average of (1 g/kg feed), and the fifth treatment T5 chicks were fed a basic ration added. It contains synthetic methionine at an average of (0.50 g/kg of feed). As for the sixth treatment, T6, its chicks were fed a basic diet to which synthetic methionine was added at an average of (0.75 gm/kg of feed), and the seventh treatment, T7, fed its chicks on a basic diet to which synthetic methionine was added at an average of (1 g). /kg feed). The results of the research showed that there was a significantly excelled(P<0.01) in the productive traits represented by live body weight, weekly weight gain, feed consumption rate, feed conversion ratio, and the qualitative traits of the carcass represented by the dressing percentage and relative growth rate in favor of the treatments to which red chili powder was added, especially the added treatment. To it (1 g/kg feed red Chili pepper powder) compared to the control treatment, and there was a noticeable improvement in the treatments for adding synthetic methionine, especially in the treatment with (1 g/kg synthetic methionine added), but it did not rise to the level achieved by the treatments adding red Chili pepper powder.
