Abstract
The present study aimed to evaluate carcass, cut yields and gastrointestinal tract biometry, the meat quality and body lesions of broiler chicken fed with four levels of corn distillers dried grain with soluble in experimental diets. A total of 700 day-old mixed flock Cobb 500 broiler chicks were distributed in a completely randomized design with five treatments, seven replicates by treatment with 20 birds each. The experimental diets were controlled with crescent inclusion levels of DDGS (4, 8, 12 and 16 %). At 35 days of age 2 broilers from each lot was selected, weighted and identified with medium weight from the experimental unit for slaughtering and evaluation of cuts yield, carcass and gastrointestinal biometry. To evaluate hock lesions and broiler meat quality. Quadratic effect was observed in reference to the weight of the carcass and chest can be included the levels up to 11.29 percent and 6.16 percent respectively. For the other variables of income of casting, edible organs and not edible and there was no significant effect on gastrointestinal biometrics, only for the total size of the gastrointestinal tract there was quadratic effect being the level of 4.25% indicated for increased size of the organs. For all welfare and meat quality variables evaluated, there was no difference between the DDGS levels used in broiler diets and control diet. These findings means that the addition of up to 16 % DDGS in diets can be an alternative to feed chicken without inducing body lesions neither altering broiler meat quality.
Highlights
Current profile of animal protein consumers has changed over the last years, they are looking for quality instead of price which supported industry and research activities to assign more value for animal welfare (Oliveira, 2015)
This study aimed evaluate carcass yield, meat quality and characterize body lesions of broiler chicken fed with experimental diets including five different dried grains with soluble (DDGS) inclusion levels
Five experimental diets were utilized with four levels of DDGS inclusion (4, 8, 12 and 16 %) and a control (0 %), each diet was offered to seven pens by treatment
Summary
Current profile of animal protein consumers has changed over the last years, they are looking for quality instead of price which supported industry and research activities to assign more value for animal welfare (Oliveira, 2015). It is common to find high incidence of chest calluses, hock lesions and pododermatitis in warehouses that have compacted litter Those findings may contribute to decreasing broiler growth rate leading economic losses mainly due meat condemnation at slaughter (Saraiva et al, 2016). DDGS can be considered source of proteins, amino acids, energy, phosphorus and many other nutrients This ingredient has high amount of non-starch polysaccharides, resulting in. Consumption of high fiber content ingredients as DDGS may influence litter quality and bring about changes in meat quality and economic losses in the carcass production. This study aimed evaluate carcass yield, meat quality and characterize body lesions of broiler chicken fed with experimental diets including five different DDGS inclusion levels
