A trial was conducted to evaluate the effect of in ovo injection prebiotic and synbiotics on growth performance, meat quality traits (cholesterol content, intramuscular collagen properties, fiber measurements), presence histopathological changes pectoral muscle (PS) broiler chickens. On d 12 incubation, 480 eggs were randomly divided into 5 experimental groups treated with different bioactives, injected: C, control physiological saline; T1 1.9 mg raffinose family oligosaccharides; T2 T3 oligosaccharides enriched probiotic bacteria, specifically 1,000 cfu Lactococcus lactis ssp. SL1 cremoris IBB SC1, respectively; T4 commercially available synbiotic Duolac, containing 500 both Lactobacillus acidophilus Streptococcus faecium addition lactose (0.001 mg/embryo). Among hatched chickens, 60 males chosen (12 birds for each group) grown 42 collective cages (n = 3 4 cages: replications groups). Broilers fed ad libitum commercial diets according age. In administration had a low investigated traits, but depend kind bioactives administered. Commercial treatment (T4) reduced carcass yield percentage, feed conversion ratio higher compared other groups. The abdominal fat, ultimate pH, cholesterol PS not affected by treatment. Broiler chickens slightly greater diameter significantly lower amount collagen. thickness fibers (not significant) density (statistically significant), observed comparison those C group, are associated broilers. incidence from examined low, which did affect deterioration obtained these birds.
