<b>Performance, gut morphometry and enzymatic activity of broilers fed neonatal supplementation in housing

Abstract: ABSTRACT. The objective was to evaluate the performance, relative organ weight, morphometry, intestinal length and pancreatic enzyme activity of broilers receiving neonatal supplementation. A total of 900 Cobb 500 broiler chicks was housed in 30 boxes of 2.5 m². The treatments were divided in a completely randomized design with six replications, and consisted of five inclusion levels (0.0, 2.5, 5.0, 7.5 and 10 grams per bird). The supplement used was based of amino acids, vitamins and minerals, which was provi… Show more

“…The effect on villus size in the jejunum and ileum at 42 days was probably due to the fact that the inclusion of proteases increases the amount of digestible peptides available for villus growth (Santos et al, 2018). Our results suggest that the use of protease signi cantly in uences the size and integrity of intestinal villi, also in uencing crypt size and the muscular V/C ratio.…”
