Funkcinio maisto ingredientų - prebiotikų įtaka paukščių organizmo fiziologinėms funkcijoms ir mėsos kokybei

Abstract

The contemporary integrated fanning is aiming to produce a broad variety of safe products and concentrates of the quality that has to match best to the needs of consumers. This is especially important in poultry production. Products of poultry industry are often mistakenly regarded as the least ecological. This myth in the consciousness of consumers was probably influenced by the intensive technology of production, which looks like something "unnatural", quite opposite to the traditional way of farming. However, according to the available references, poultry meat can be assigned to the category of functional food. The aim of our study was to investigate the influence of the new prebiotic feed additive BIO-MOS on the physiological functions and meat quality of broilers. The investigation was performed in 2005 at the Laboratoiy of Biological Diversity and Technologies of Vilnius Pedagogical University and on the broiler farm "Petkus". Day-old Ross broiler chickens were assigned into two groups, trial and control, of 100 chickens each (50 males and 50 females). Broilers of both groups were given feed of the same composition and nutritional value, just for the trial group the prebiotic additive BIO-MOS was mixed into the feed. The inclusion rate was different at different age periods of the chickens: 0-7 d. -2 kg, 7-35 d. - 1 kg and at 35-39 d. - 0.5 kg/t of feed. The results showed that the prebiotic additive BIO-MOS had a positive effect on the digestion process, the growth of chickens and the quality of meat. Results of anatomical analysis of carcasses and chemical analysis of the meat of broilers at 39 days of age showed that addition of BIO-MOS had a positive effect on some meat quality parameters: the meat of both male and female chickens contained more dry matter, protein and fat. The study was financed by Lithuanian State Science and Studies Foundation.
