Probiotikų poveikis paukščių fiziologinėms funkcijoms / The effect of probiotics to the birds physiology functions

In today’s poultry new ways are finding how to increase the bird’s productivity, to improve the quality of production. The feed additives which stimulate the growth, consolidate the immunity, improve the quality of meat are using for better appropriation of nutrient.
It is necessary to regard that preparation witch are bringing into feeds would be natural, their garbage wouldn’t stay in the terminal product, wouldn’t raise resistance for antibiotics and wouldn’t do other effect for consumer health. Before antibiotics were used for this purpose, but nowadays more often they are exchanging into natural probiotical preparations.
In this job are analyzed practice facilities of the probiotic Bio Plus 2 B in the Ross chicken broilers feeds and was trying to motivate in physiology this probiotic preparation influence to the growth of chickens, to the index of blood and to the quality of meat.
Researches of the blood index was showed: the stock of the nucleic acid was increased from 12,69 % (P<0,05) to 22,41 % (P<0,001), total proteins – from 8,50 % (P<0,05) to 17,68 % (P<0,001), lipids – from 8,69 % (P<0,05) to 25,43 % (P<0,001) and triglycerides – from 5,00 (P<0,05) % to 16,38 % (P<0,001). The alive mass was increased from 6,7 % (P<0,05) to 14,51 % (P<0,001).
Researches of the meat chemical composition was showed that the stock of dry material in chickens breast muscles was increased for the effect of probiotic preparation from 23,67 % to 24,01 %, from 21,87 % to 22,37 %... [to full text]
