Objetivou-se avaliar de forma quantitativa a incubabilidade e qualitativa a qualidade dos pintos das galinhas caipiras Peloco e Caneludo do Catolé através de avaliações da qualidade do ovo, desenvolvimento embrionário e eclodibilidade além das principais características do pinto ao nascer. Coletou- se ovos por um período de 15 dias, os quais foram armazenados em sala de estocagem, a temperatura media de 17ºC ±1 e UR entre 70 e 75%. Pesaram-se os ovos após coleta e aos 18 dias de incubação, perdas de peso apresentadas na estocagem: 0,77% Peloco e 0,88 % Caneludo; e aos 18 dias de incubação: 10,53% Peloco e 11,22% Caneludo. Incubou-se 277 ovos Peloco e 273 ovos Caneludo, em máquina de estagio único durante 21 dias com 37,5 ºC e 57 a 60% UR. Outras variáveis avaliadas: peso do pinto pós eclosão, eclosão e eclodibilidade, obtendo-se (36,58g, 68,13% e 77,15% Peloco) e (39,07g, 77,15% e 74,10% Caneludo). Realizou-se mortalidade embrionária através do embriodiagnóstico, dividida por fases: inicial (1 a 5 dias), intermediaria (6 a 15 dias) e final (16 a 21 dias). Observou-se para ovos férteis não eclodidos e mortalidade embrionária por fases: 22,84; 28,30; 16,98 e 54,72% Peloco e 25,30; 10,80; 10,80 e 78,40% Caneludo respectivamente. Os ovos inférteis: Peloco 45,92% e 25,30% Caneludo. Avaliou-se a qualidade do pinto através do ScorePasgar©, obtendo 9,20 Peloco e 9,17 Caneludo. Concluiu-se que as características de incubação e a qualidade dos pintos, são satisfatórias, pois estas aves não passaram por programa de melhoramento genético até o momento.
Determine levels of digestible lysine for free-range chicken of the Caneludo Catolé, during the initial, growth and termination phases. Were used150 male and female poultry in confinement cages. The digestible lysine levels used per phase: initial (1-30 dias) 0.856, 0.978, 1.100, 1.223, 1.345%, growth (30-75 dias) 0.705, 0.806, 0.906, 1.007, 1.108% and termination (75-105 dias) 0.624, 0.713, 0.802, 0.891, 0.980%. Five treatments, three replicates, 10 chickens per experimental unit, distributed in a completely randomized design. Parameters of zootechnical evaluated: feed intake, weight gain, feed conversion ratio. The carcass characteristics evaluated: carcass, breast, drumstick, thigh, wing, neck, back, foot, gizzard, liver and heart yields. Meat quality evaluated: pH, shear force (kgf/g), cooking weight loss (%).The levels of digestible lysine influence in the initial phase with quadratic effect (P<0.01) in weight gain 1.225% and feed conversion ratio 1.175%. In the growth phase digestible lysine had a positive linear on feed intake (P<0.05) and weight gain (P<0.01) and linear decrease (P <0.01) for feed conversion ratio. In the termination phase, feed intake linearly increased (P<0.05), weight gain and feed conversion were quadratic (P<0.01), with levels calculated as 0.757 and 0.713%, respectively. Increasing linear responses were observed for carcass (%), breast (P<0.05) and drumstick (P<0.01) yields. The pH of the breasts showed a linear increasing effect (P<0.01), while shear force and cooking weight loss had a linear decreasing effect (P <0.01) with the increase of digestible lysine levels. The levels of digestible lysine recommended per phases: 1.175% initial, 1.108% growth and 0.713% termination.
