| CONCLUSION
The study of the chemical composition and nutritional value of eggs from hens supplementation with mineral and fishmeal additives in diet has showed the positive influence on eggs quality indicators and morphometric parameters. A higher content of protein, carbohydrates and energy value of eggs were observed. The supplementing diet had a significant effect on the fatty acid profile of yolk amino acids. Feeding with supplementing diet in mineral and protein led to an increase in total fatty acids content and dietary mono (MUFA) and polyunsaturated fatty acids (PUFA). The vermiculite contributed to a significant increase in the concentrations of C18:2 n-6 and C18:3 n-3 fatty acids and total PUFAs in yolk lipids. The amount of protein, WBC, HGT, calcium hens group was higher in the group fed with combination of V+FM. These results allowed concluding that high mineral nutritional value gives a perspective of the use vermiculite additive in the production of high quality poultry products. For future poultry industry, especially in developing countries, this novel knowledge of vermiculite as feed additive is very important for better understanding how to improve eggs properties and quality ensuring consumers' health and safety.

ABSTRACT In this experiment the effects of supplementing laying hen’s diets with vermiculite (V) and vermiculite mixed with fishmeal (FM) on productivity, morphometric parameters, chemical composition and fatty acid profile of eggs, and some blood plasma indicators of laying hens were studied. "Hajseks white" birds were randomly divided into 5 groups (20 birds per group) and 24 weeks of age hens were fed 2 months: A-base diet (BD) (control group), B and C-base diet with 3% or 5% vermiculite and D and E-base diet and 1% vermiculite + 2% fish meal or 1% vermiculite + 3.5% fish meal. In two tested groups of hens fed with vermiculite plus fishmeal productivity of eggs was higher than control group. Hens groups B and C laid 100 eggs more than control group and group D and E about 200 eggs more after feeding with V+FM. A higher content of protein, carbohydrates and energy value of eggs were observed. Average egg weight was the highest in group E (63.3 g), also weight of protein, white and yolk of egg. Eggs of hens group C had the highest parameters of weight, thickness and density of shell. The results showed that supplementation of V+F significantly affected concentration of the fatty acid (FA), protein content in the yolk and white. Feeding with supplementing diet in mineral and protein led to an increase in total fatty acids content and dietary mono (MUFA) and polyunsaturated fatty acids (PUFA). The level of n-6 FA (especially linoleic and linolenic acids) was significantly increased in eggs of hens group D and E. The amount of protein, WBC, HGT, calcium of hens group fed with combination of V+FM was higher. The high mineral nutritional value gives a perspective of the use vermiculite additive in the production of high quality poultry products. For future poultry industry, especially in developing countries, this novel knowledge of vermiculite as feed additive is very important. жүктеу/скачать 0,93 Mb. Достарыңызбен бөлісу:
