Poultry product manufacturing using by-products of fat-and-oil industry

The article presents the results of the use of "Gorlinka" concentrate in the feeding of broiler chickens of the cross "Ross 308". Differences in poultry feeding were as follows: the chickens of the control group were fed mixed fodder (with sunflower seed meal) used at the poultry farm, and the chickens of experimental control-mixed fodder in which a new feeding product was introduced instead of 75% of the sunflower seed meal. Housing and feeding conditions, as well as other requirements, corresponded to the standard of the cross "Ross 308". The duration of the experiment corresponded to the period of broiler farming at the poultry farm (37 days). It should be noted that the introduction of the studied concentrate had a positive effect on the poultry meat productivity, which is confirmed by the results of the weekly weighing. Thus, the total and average daily live weight gain of the poultry during the fattening period was higher in the experimental group than in the control one by 141.2 g and 3.98 g, respectively. The feed consumption by volume in the experimental group was lower than in the control group by 10.63%. The morphological and biochemical compositions of the blood of the poultry were also studied. The analysis showed that the studied haematological parameters of the poultry were within the physiological norm. However, it is important to note that in the blood of the experimental group poultry, as compared to the control group, was observes a slight increase in the red cell content by 0.12 10¹²/L, the total protein by 2.1 g, calcium by 0.24 mmol/L and phosphorus by 0.25 mmol/L. The obtained data of haematological studies show, first of all, that poultry feeding is nutritious and improves the metabolic processes in the body. The slaughter yield of chickens of the experimental group was higher than in the control group by 1.98%. The protein content in the breast and thigh muscles of the control group was 22.12% and 21.05%, and of the experimental group-22.61% and 21.4%, respectively. The amino acid content in the breast and thigh muscles was higher in the experimental group than in the control group by 1.89% and 1.42%. The additional profit due to the use of a new local feed additive in the mixed fodder for meat poultry was 1085.53 rubles.
