Knowledge of protein requirements of pigs during the first phase of life is crucial for both achieving high growth rates and avoiding nitrogen waste.

Twelve male pigs were individually reared indoor, fed with four isoenergetic diets with different levels of CP (18, 16, 14 and 12%) equally distributed among animals. The animals, with an initial average live weight of 27 kg, were fed ad libitum and slaughtered after 2 months of trial. Left side carcass was sectioned in six cuts: head, neck, loin, shoulder, ham and ribs. Each cut has been dissected into the main tissues. As regards in vita performance a slightly higher growth rates with decreasing protein levels were recorded (ADG of 0.781, 0.774, 0.755 and 0.729 kg/d respectively for 12, 14, 16 and 18% of CP), though only the two extreme levels of CP (12 vs 18%) resulted statistically different (P=0.05).

Abstract

Knowledge of protein requirements of pigs during the first phase of life is crucial for both achieving high growth rates and avoiding nitrogen waste. Autochthonous breeds possess specific requirements in this regard and the literature is poor even for the Cinta Senese breed. Thus, the effect of different level of crude protein (CP) in Cinta Senese pigs, between 30 and 60 kg, was evaluated within the TREASURE* project. Twelve male pigs were individually reared indoor, fed with four isoenergetic diets with different levels of CP (18, 16, 14 and 12%) equally distributed among animals. The animals, with an initial average live weight of 27 kg, were fed ad libitum and slaughtered after 2 months of trial. Left side carcass was sectioned in six cuts: head, neck, loin, shoulder, ham and ribs. Each cut has been dissected into the main tissues. As regards in vita performance a slightly higher growth rates with decreasing protein levels were recorded (ADG of 0.781, 0.774, 0.755 and 0.729 kg/d respectively for 12, 14, 16 and 18% of CP), though only the two extreme levels of CP (12 vs 18%) resulted statistically different (P=0.05). Cuts weights and percentage of the main tissues were similar between diets. The diet with 12% of CP may be the optimal compromise for the growth of the Cinta senese pigs from 30 to 60 kg of live weight.
