Response of Broiler to Addition Dimethylglycine of Normal and Low-Energy Diets in Productive Performance

Abstract

Abstract The research was conducted in poultry fields in the Department of Animal Production / College of Agriculture / University of Anbar for the period starting from the third of September 2022 until the fourteenth of December 2022 (42 days), and The purpose of the study was to find out the effect adding dimethylglycine to diets Regular and low-energy diets on productive performance of broiler chickens. 180 Ross 308 unsexed chicks, 1 day old and average weight of 37.8 g, were used, distributed to two groups depending on the energy level in the diet (normal diet and low energy diet), each group was treated with dimethylglycine at levels (0, 300 and 600 mg / In kg of fed), The results showed a significant improvement (P < 0.05) for the addition treatments 0, 300 and 600 mg / kg feed in average body weight, weight gain and feed conversion factor compared to control treatments. As for the interaction between the trait of the diet and the additives, a significant improvement (P < 0.05) was observed in the treatment of the regular ration by adding 300 DMG / kg feed compared to the rest of the treatments, then this was followed by the treatment with reduced food rations without addition or with the addition of 300 DMG / kg fed. We conclude that adding DMG at the above levels to the regular and low-energy diets The productive performance of broilers improved without any negative effect.
