Resumo: | This experiment was developed to compare the performance and uniformity of broilers chickens as related to sex and different stocking rates. 1800 one day Ross breed chicks were distributed in 36 boxes, on a completely randomized block design, 3x2 factorial, with 3 sex (male, female and mixed) and 2 stocking (10 and 15 birds/m²). There were six replications per treatment, with 40 or 60 birds per replication. The experimental ration was formulated with corn and soy bean meal. The results were taken weekly, and after 45 days the animals were slaughtered. The results showed an increase in weight, consumption food, food conversion and daily weight gain in the smaller stocking, with statistical significance (p<0,05) for: food consumption (all period) and food conversion (1-21 and 22-45 days). However, the increase in stocking showed better values in viability and uniformity. With regard the sex, better values were seen for males, with statistical significance (p<0,05) for weight (21 and 45 days), food consumption(22-45 and 1-45 days), food conversion (1-45 days) and daily weight gain. |

With regard the sex, better values were seen for males, with statistical significance (p<0,05) for weight (21 and 45 days), food consumption(22-45 and 1-45 days), food conversion (1-45 days) and daily weight gain.O experimento teve a finalidade de comparar o desempenho e uniformidade de frangos de corte separados por sexo e criados em diferentes densidades populacionais. Para tanto foram utilizados 1800 pintos de 01 dia da linhagem Ross, distribuídos em 36 parcelas experimentais (Boxes), de acordo com um delineamento experimental tipo blocos ao acaso, obedecendo um modelo fatorial 3x2 com 3 sexos (Machos, Fêmeas e Misto) e duas densidades populacionais (10 e 15 aves/m²), com 6 repetições por tratamento, sendo 40 ou 60 aves por repetição. As rações experimentais foram formuladas à base de milho e farelo de soja. Foram efetuadas medidas semanais de consumo de ração e peso dos animais, e ao final de 45 dias os animais foram abatidos. Ao final do período experimental, os resultados mostraram que os maiores valores de peso, consumo, Conversão Alimentar e Ganho Médio Diário foram verificados na menor taxa de lotação empregada, havendo significância estatística (p<0,05) para os itens : consumo (todos os períodos) e Conversão Alimentar (1-21 e 22-45 dias). Todavia, o incremento na taxa de lotação apresentou maiores viabilidade e uniformidade.Quanto aos sexos empregados, foram observados melhores valores para os machos, havendo diferença significativa (p<0,05) para peso corporal (21 e 45 dias), consumo (22-45 e 1-45 dias), Conversão Alimentar (1-45 dias) e Ganho Médio Diário.Universidade de São Paulo.
