Última Small intestine development of laying hens fed different fiber sources diets and crude protein levels Rev. Bras. Ciênc. Avic. Praes,MFFM; Pereira,AA; Sgavioli,S; Duarte,KF; Alva,JCR; Domingues,CH de F; Puzzoti,MM; Junqueira,OM. The objective of the presente study was to evaluate the effects on different dietary fiber sources and crude protein levels on the intestinal morphometry of commercial layers. Isa Brown® layers with 48 weeks of age were distributed in a completely randomized experimental design with a 3 x 2 + 1 factorial arrangement, resulting in seven treatments with seven replicates of eight birds each. At the end of the fourth experimental period (28 days each), birds were 64 weeks of age and were randomly chosen (two birds per replicate, totaling 14 birds per treatment), weighed and sacrificed by neck dislocation. Their intestine was dissected and the duodenum, jejunum and ileum were collected for subsequent analysis of intestinal morphometry. Treatments consisted of...

Bras. Ciênc. Avic. Norouzian,H; Alirezaei,M; Dezfoulian,O; Taati,M. ABSTRACT The capacity of the chicken intestinal tract to digest and absorb nutrients is not fully developed on the day of hatch. The aim of this study was to investigate the role of betaine on the intestinal development of broiler chickens, including brush border enzyme activities indices and morphological changes during the first week of growth. Fiftyone-day-old Ross 308 broiler chickens were randomly distributed into five groups: control (C), low methionine(LM), low methionine plus betaine (LM+B), betaine 1 (B1) and betaine 2 (B2). Betaine was dissolved with a concentration of 500 mg/L in the drinking water of LM+B and B1groups and a concentration of 1000 mg/L in the B2 group. Histological assessment showed lower duodenal crypt depth and villi...
