Increased requirements for quality and safety of agricultural products formed the basis for the study of the use of probiotics in broiler poultry.In this regard, the study for the replacement of antibiotics safe for animal and human health drugs, the development of technologies for producing safe food is a priority.
One alternative solution to this problem may be probiotics, and products derived from them.At the same time, as shown by multiple studies can be grown broiler chickens without antibiotics, under certain conditions, replacing them will probiotics .
However, despite the widespread bans on the use of feed antibiotics, is still quite difficult to break the stereotype that it is impossible to grow without antibiotics bird.The main priority in the production of poultry products still make a profit, not to ensure product quality and safety.Specialists make feeding rations for feeding the birds on the recommendations of suppliers and crosses its sole discretion, without taking into account many factors.When outdoor poultry has the ability to be fed up with missing products from the litter that is inaccessible to birds in a cage.
Thus, studies were conducted to determine and justify the need for poultry feed additives containing micro-organisms in growing broiler chickens.
To realize this objective have been formulated the following research problems:
- Set the effect of probiotic feed additive to the terms of formation and the quality of the microbial landscape of broiler chickens.
- determine the dependence of the level of consumption of broiler chickens of different probiotics monokultkur of the presence in their composition enzymes.
- determine the relationship between changes in the qualitative composition of intestinal microflora and immune resistance of the organism of broiler chickens.
broilers cross ISA was skomplektovat 2 groups of 38 chickens, day-old counterparts.All chickens were subjected to veterinary treatments planned.
control group of broiler chickens received the basic diet.The cell comprising the test group chickens were installed automatic feeders 4, wherein at least poured eating feed premix enriched with lactic acid feed additive (MCD): I - based on lactic acid bacteria, MXD-A;II - on the basis of lactic acid Streptococcus thermophilus, MCD-C;III - based bifidobacteria MXD-B;IV - based on propionic acid bacteria, ICD-P. Premixes based on microorganisms fed broilers within three weeks, with free access to all feeders.It should be noted that during the experiment in the experimental groups feed enzymes and antibiotics were not used.
During research conducted metering feed, feed additives MKD (L, C, R, B), body weight, and the safety of the birds.In 30 min.after hatching and then 7, 14, and prior to slaughter - 42 days.fragments were sampled to determine the effect of the intestine to form ICM qualitative composition of intestinal microflora of broiler chickens.
The studies identified the need of broiler chickens in feed additives containing live monoculture of bacteria (bifidobacteria, lactobacilli, propionic acid bacteria and lactic streptococci).Furthermore, it was found that regardless of age chicks prefer main representatives of the intestinal microflora of poultry species - bifidobacteria and lactobacilli.The use in the diet of broiler premix based on monocultures has a positive effect on the speed and quality of the settlement of the intestinal microflora of chickens representatives of their own flora and positive impact on productivity and safety performance of broiler chickens in the process of growing.
