Resumo: An experiment was conducted to investigate the development of the digestive system in slow-growing broilers of different strains. The experiment involved a total of 544 one-day-old chicks, 136 of each of four genotypes, namely, Label Rouge Pesadão, Label Rouge Pescoço Pelado, Carijó and Carijó Pescoço Pelado. The birds were distributed in a completely randomized design with four treatments (genotypes) and eight replicates of 17 animals each. Live weight, digestive tract development and intestinal histomorphometric measurements were evaluated at different ages. Significant differences (p < 0.05) were observed between the strains for live weight, relative weight and length of digestive tract organs and intestinal histomorphometric measurements at one, seven and 28 days of age. The Carijó strain showed greater weight and development of digestive organs than the Carijó Pescoço Pelado strain. There was a difference (p < 0.05) for histomorphometric measurements of the small intestine between the strains at the evaluated ages. The Carijó Pescoço Pelado and Label Rouge Pescoço Pelado strains showed higher villi and higher villus:crypt ratios in the duodenum, jejunum and ileum. The slow-growing strains differ in performance regarding the relative weights and lengths of digestive tract organs and intestinal histomorphometric measurements.

Foram utilizados 544 pintos com um dia de idade, sendo 136 de cada genótipo sendo: Label Rouge Pesadão, Label Rouge Pescoço Pelado, Carijó e Carijó Pescoço Pelado. Distribuídos em um delineamento inteiramente casualizado com quatro tratamentos (genótipo) e oito repetições de 17 animais cada. As variáveis estudadas foram peso vivo, desenvolvimento do trato digestório e medidas histomorfométricas intestinal em diferentes idades. Houve diferença (p < 0,05) entre as linhagens no peso vivo, peso relativo e comprimento dos órgãos do trato digestório e medidas histomorfométricas intestinal com um, sete e 28 dias de idade. A linhagem Carijó apresentou maior peso e desenvolvimento de órgãos digestórios comparada a linhagem Carijó Pescoço Pelado. Houve diferença (p < 0,05) para medidas histomorfométricas do intestino delgado entre as linhagens nas idades avaliadas. As linhagens Carijó Pescoço Pelado e Label Rouge Pescoço Pelado apresentaram maior altura de vilo e relação vilo:cripta do duodeno, jejuno e íleo. As linhagens de crescimento lento apresentam diferenças entre si no desempenho peso relativo e comprimento de órgãos do trato digestório e nas medidas histomorfometricas do intestino.UEL2021-01-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3996810.5433/1679-0359.2021v42n1p319Semina: Ciências Agrárias; Vol. 42 No. 1 (2021); 319-334Semina: Ciências Agrárias; v. 42 n. 1 (2021); 319-3341679-03591676-546Xreponame:Semina.
