The nutritional value analysis of different genotypes of barley, triticale and wheat and efficiency using of whole cereal grains in broiler chickens feeding

Abstract

The aim of the study: To investigate nutritive value of a variety of barley, wheat and triticale genotypes and influence of whole barley and triticale used in various amounts on broilers’ productivity, digestive processes and morphological composition and quality of poultry meat. Objectives of the study: 1. To investigate nutritive value of a variety of barley, wheat and triticale genotypes under concretely defined conditions of their growth. 2. To determine impact of various genotypes of barley and triticale on transit, viscosity of broiler chickens’ digesta and ammonia nitrogen concentration in the content of cecum. 3. To examine impact of various whole barley amounts on broilers’ productivity, digestive processes and quality of poultry meat. 4. To examine impact of various whole triticale amounts on broilers’ productivity, digestive processes and quality of poultry meat. Actuality and novelty of the work: Whole triticale is most frequently used for broiler chickens’ feeding. Their usage preconditions a better development of digestive system and decreases the cost of poultry meat production. The use of whole barley and triticale for broilers’ nutrition is scarcely investigated, whereas the price of aforesaid grains is frequently lower comparing with that of wheat. Besides, nutritive value of barley and triticale has not been completely investigated; there is no published data on the in-fluence of whole barley and triticale (used in various amounts at different growth periods) on broilers’ productivity, physiological processes, digestion and quality of poultry meat. Therefore, the investigation is actual and timely. In this study, concentrations of β-glucanes, pentosans, phenolic acids, trace elements, and flavonoids in various genotypes of barley, triticale and wheat were determined and publicized for the first time. Using two different investigation methods (liquid chromatography and near infrared spectroscopy) general and prececal amino acids amounts in grains of various crops were investigated. For the first time, effect of triticale and barley of various genotypes on viscosity of digesta, its transit and on cecal concentration of ammonia nitrogen in broiler chickens was determined. Various whole barley and triticale amounts (used for broilers’ nutrition at different periods of their growth) were analyzed; their influence on viscosity of poultry digesta, on concentration of ammonia nitrogen and short chain fatty acids in cecal content was evaluated; influence of whole barley and triticale in chicken feeds on the composition of fatty acids, atherogenic, trombogenic indices, sensory and textural properties in poultry meat was examined
