РАЗРАБОТКА ЭКСПЕРИМЕНТАЛЬНЫХ СТАРТЕРОВ ДЛЯ МОЛОДНЯКА КРУПНОГО РОГАТОГО СКОТА НА ОСНОВЕ ОТХОДОВ ПИЩЕВОЙ ПРОМЫШЛЕННОСТИ

Abstract

This article describes the production technology and nutritional characteristics of starters for calves based on food production waste such as substandard eggs, whey and yeast grown on grain bard as a method of processing thereof to obtain an alternative to factory feed products. The zootechnical analysis of the prepared starters revealed a high protein content and significant nutritional value. The protein content in the experimental starters exceeded 20%. Specifically, "Starter A," based on egg powder from substandard eggs, had a protein content of 20.98%, while "Starter B," based on feed yeast, had a content of 21.58%. Special attention was given to the feasibility and economic aspects of producing these starters. It was also found that "Starter A" is the most cost-effective feed. The production cost of egg powder-based "Starter A" was 172.78 tenge, while "Starter B" cost was 269.4 tenge. The difference in their costs was 96.62 tenge, or 64.1%. It was also concluded that the experimental feed additives are not inferior in nutritional value to the factory equivalent and are characterized by lower production costs.
