ABSTRACT This study aimed to investigate the effects of xylanase (Xyl) individually or in combination with B. subtilis and B. licheniformis associated or not with yeast cell wall in pig diets with a reduction of 100 kcal/kg of metabolizable energy (ME) content. Pig performance, bone parameters, intestinal morphometry, and bioeconomic indices were evaluated. A total of 75 pigs (25 females and 50 barrows; 25.02±3.21 kg) obtained from crossing Large White × Landrace were used. The experimental design consisted of randomized […]

It was evaluated the effect of different levels of probiotics in the diet on performance, carcass yield, noble cuts and abdominal fat, intestinal pH and blood parameters of broilers at 1 to 40 days of age fed ingredients of vegetal and animal origin. It was used 1.000 line Cobb 500 broilers, distributed in a complete random design with 10 treatments, each one with 5 replicates of 20 broilers per experimental unity, allocated in a reused litter. The probiotic which was […]

Three experiments were conduced with the purpose of evaluating the effect of the addition of probiotics in the diet of broilers on the characteristics of reused litter and lesions of chest, knee and feet. Eight hundred male chicks, one day old, from Ross Commercial Breeding, were utilized in each experiment. The animals were housed in 20 pens in a populational density of 10 birds/m2. The experimental design was completely randomized and the treatments were organized in a 2 x 2 […]
