Resumo: | A total of 375-day-old naked neck chicks were distributed in a completely randomized design in five diets with 0, 2, 4, 6, and 8% macaúba meal levels to evaluate colonial broiler chickens. The data were submitted to linear or quadratic regression analysis according to the best fit for each studied variable using the statistical program SAS 9.0. Macaúba meal levels increased feed intake without influencing weight gain, resulting in worsening feed conversion and leading to a linear reduction in slaughter weight at 85 days and reduction in carcass yields due to higher abdominal fat deposition. Linear effects were found on the contents of a*, pH, ethereal extract, and ash in the breast and b*, moisture, ethereal extract, and ash in the drumstick + thigh. Thus, macaúba meal inclusion in the diet of naked neck broilers impaired performance by increasing diet intake, impairing feed conversion and reducing carcass yields. However, it favors breast, drumstick, and thigh colors because it is rich in carotenoids.Keywords: Acrocomia aculeata. Alternative foods. Alternative poultry farming. |

MACAÚBA MEAL LEVELS IN THE DIET OF NAKED NECK BROILERSNÍVEIS DE FARELO DE MACAÚBA NA DIETA DE FRANGOS DE CORTE DE PESCOÇO PELADOA total of 375-day-old naked neck chicks were distributed in a completely randomized design in five diets with 0, 2, 4, 6, and 8% macaúba meal levels to evaluate colonial broiler chickens. The data were submitted to linear or quadratic regression analysis according to the best fit for each studied variable using the statistical program SAS 9.0.

Linear effects were found on the contents of a*, pH, ethereal extract, and ash in the breast and b*, moisture, ethereal extract, and ash in the drumstick + thigh. Thus, macaúba meal inclusion in the diet of naked neck broilers impaired performance by increasing diet intake, impairing feed conversion and reducing carcass yields. However, it favors breast, drumstick, and thigh colors because it is rich in carotenoids.Keywords: Acrocomia aculeata. Alternative foods. Alternative poultry farming.Para avaliar níveis de farelo de macaúba na dieta de frangos de corte tipo colonial foram utilizados 375 pintos de um dia, da linhagem pescoço pelado, distribuídos em delineamento inteiramente casualizado. em 5 dietas com níveis de 0, 2; 4; 6; e 8% de farelo de macaúba. Os dados obtidos foram submetidos a análises de regressão linear ou quadrática, conforme o melhor ajustamento obtido para cada variável estudada, utilizando-se o programa estatístico SAS 9.0. Os níveis de farelo de macaúba aumentaram o consumo de ração sem influenciar no ganho de peso, resultando na piora da conversão alimentar. Causaram redução linear no peso de abate aos 85 dias e redução nos rendimentos de carcaça em função da maior deposição de gordura abdominal. Foram observados efeitos lineares nos teores de a*, pH, extrato etéreo e cinzas no peito e sobre os teores de b*, umidade, extrato etéreo e cinzas na coxa + sobrecoxa. Conclui-se que a inclusão do farelo de macaúba na dieta de frangos de pescoço pelado prejudica o desempenho por aumentar o consumo da dieta, prejudicando a conversão alimentar e reduzindo os rendimentos de carcaça. Entretanto, por ser rico em carotenoides favorece a coloração de peito, coxa e sobrecoxa.Palavras-chave: Acrocomia aculeata. Alimentos alternativos.
