The use of sugar sorghum in the diets of broiler chickens

Abstract

In order to ensure high productivity of poultry compound feeds are required. However, their production is limited by the lack of high-energy and protein feed in the country. In recent years, many farms are increasingly using the reserve of intensification of feed production, such as the cultivation of new and sparsely distributed forage crops. In this regard, more and more attention is drawn to sugar sorghum, which has received a high rating not only as a productive and drought-resistant crop, but also as the culture that has excellent feed qualities. The results of studying the influence of compound feed with sugar sorghum seeds on zootechnical, physiological and economic indicators when raising broiler chickens have been presented in the article. The researches have been carried out on broiler chickens from the age of one day to 42 days. Two groups of broiler chickens have been formed (control and experimental) per 50 heads in each to conduct the experiment. It has been found during the researches that when input in structure of the diet of 30 % of sugar sorghum the increase of live weight of broilers by 4,16 %, the average daily feed intake 2,82 %, and reduced expenditures of feed per 1 kg of daily gain by 1,67 %. The use of experimental compound feed has increased the digestibility of nutrients by broiler chickens: raw protein by 0,48 %, raw fat by 2,50 %, and raw fiber by 4,93 %. It has been found on the base of the results of anatomical cutting of broiler chicken carcasses that the experimental group contained more edible parts and muscles compared to the control group. The level of profitability of broiler meat production in the experimental group has exceeded the indicator of the control group by 5,4 %.
