Resumo: This experiment was conducted to study the effects of three stocking densities (10, 12 and 14 birds/m2), three litter types (rice hull, colonião grass (Panicum maximum, jacq.) and elephant grass C. V. napier (Pennisetum purpureum, schum.) and two lines (Arbor Acres and Hubbard) on the productivity index of broilers in the period 1 (1-28 days), 2 (29 -45 days) and total (1-45 days). Five hundred four chicks were used in a randomized block design with factorial arrangement of 3x3x2x2. Commercial ration were given containing 22% and 19% of crude protein in the periods 1 and 2, respectively. The studied characteristics were: mean body weight, daily mean weight gain, viability, production per unit of area and productive efficiency index. The different lines had significant effects (P < 0,01) on all characteristics except viability in all periods and productive efficiency index in period 2, the line Hubbard showed the highest averages. The different litter types had no significant effects ( P > 0,05) on all studied characteristics, except production per unit of area and productive efficiency index in period 1, to which it was observed significative interaction of line x litter. The stocking densities affected linearly ( P < 0,01) only the characteristic production per unit of area.

The stocking densities affected linearly ( P < 0,01) only the characteristic production per unit of area.   O experimento foi realizado com o objetivo de estudar os efeitos de três densidades populacionais (10, 12 e 14 aves/m2), três tipos de camas (casca de arroz, capim colonião e capim elefante var. napier) e duas linhagens, Arbor Acres e Hubbard) sobre os índices de produtividade de frangos de corte nos períodos 1 (1 a 28 dias), 2 (29 a 45 dias) e total (la 45 dias). Utilizou-se 504 pintos de um dia, em um delineamento experimental em blocos casualizados com arranjo fatorial 3x3x2x2. Foram fornecidas rações comerciais contendo 22% e 19% de Proteína Bruta nos períodos 1 e 2, respectivamente. As características estudadas foram: peso corporal médio, ganho de peso médio diário, viabilidade, produção por unidade de área e índice de eficiência produtiva. Observaram-se efeitos significativos ( P < 0,01) das diferentes linhagens sobre todas as características estudadas, exceto sobre a viabilidade, em todos os períodos estudados e sobre o índice de eficiência produtiva no período 2, sendo que a linhagem Hubbard apresentou maiores médias. Os diferentes tipos de camas não afetaram significativamente ( P > 0,05 ) nenhuma das características estudadas, com exceção de produção por unidade de área e índice de eficiência produtiva, no período 1, para as quais foram observadas interação significativa de linhagem x cama. As densidades populacionais afetaram linearmente ( P < 0,01) apenas a característica de produção por unidade de área.    UEL1994-01-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/439210.5433/1679-0359.1994v15n1p40Semina: Ciências Agrárias; Vol. 15 No. 1 (1994); 40-47Semina: Ciências Agrárias; v. 15 n. 1 (1994); 40-471679-03591676-546Xreponame:Semina.
