Increasing the nutritional value of compound feed for Broiler chicken due to the introduction of fish concentrate

Introduction. Feed makes up 65,00 – 70,00 % of the total cost of growing in the poultry industry [2]. Animal protein is the most expensive component of compound feed for birds and makes up over 15,00 % of the total cost. In many poultry industries, fishmeal is the traditional animal protein for complete feed production, but it is expensive and lowers the expected profits of the poultry industry. On the other hand, excessive demand for poultry meat and eggs has increased the need for new feed components to support intensive poultry production. Thus, the feed industry needs an alternative source of highly digestible protein with a suitable amino acid profile to replace traditional protein sources. The fish concentrate studied by us has promising advantages in this respect. Fish concentrate «VolgaFish» is a by-product of aquaculture production with a higher nutritional value, has a crude protein content of 50,00 %, crude fat – up to 17,50 %, crude ash – up to 20,00 %. In addition, the fish concentrate studied by us contains a large amount of important fatty acids and minerals (especially calcium and phosphorus), in this regard, it is successfully integrated as a feed element in the poultry diet.

Object. The object of the study was the agricultural bird of the fast-growing cross ROSS-308.

Materials and methods. The methodological basis of the research was the scientific developments of the authors who studied the use of non-traditional feed products in the cultivation of poultry for meat productivity. The presented studies were carried out in the period from 2021 to 2023. In the conditions of the the Federal State Budget Educational Institution of Higher Education «Volgograd State Agrarian University» on the poultry of the ROSS-308 cross. To perform the study, four groups were formed in three repetitions: control, 1-experimental. 2-experienced and 3-experienced 40 heads each. The poultry was raised from the daily to 37-day age with outdoor maintenance. The chickens were kept on a deep litter (sawdust), the feeding technology, watering and microclimate parameters meet the requirements of the ROSS-308 cross.

Results and conclusions. The chemical composition of fish concentrate exceeds fish meal in terms of crude protein by 2,15 %, crude fat by 0,25 %, crude ash by 0,28 %, which suggested the replacement of fish meal in broiler chicken feeding programs with this feed product. The use of «VolgaFish» fish concentrate in the feed for broiler chickens, which replaces 50,00 %, 75,00 % and 100,00 % fishmeal, made it possible to increase the average daily gain of poultry by 1,38-5,18 %, and the live weight individuals by 37 days of age by 1,32-5,01 %.
