Patrón de consumo de cerdos Pelón Mexicano alimentados con dieta de Aguacate (Persea americana Mill.)

A total of eight castrated male pigs, four Mexican Pelon and four improved (predominantly Yorkshire x Large White) pigs with a live weight of approximately 30 kg were used to study the pattern of consumption of diets in the form of grain and cereal flour. 20% of substitution for fresh avocado pulp (Persea americana Mill.), According to a 2x2 shift design where the factors one type were the type of animal, and the diet (0 and 20% avocado pulp) . The food behavior was recorded by direct observation during the two consecutive hours and immediately to the distribution of the food. No significant effect (P> 0.05) was found on the genotype x diet interaction in any measure. It was found that there was no effect of genotype in the time that eating, the speed of ingestion and the visits to the trough. In contrast, the effect of diet was evident for most of the traits that describe the pattern of consumption. During the two consecutive hours of food distribution, the feed intake was 67.8 and 69.1% of the feed in improved pigs and in the Mexican Pelon (P> 0.05), or 84.4 and 52.5% in diets with or without 20% Avocado (P <0.001). The rate of ingestion seemed to be influenced by the genotypes and diets examined, and on average was 28.9 g MS / min. It is suggested that the provision of conventional diets substituted by fresh avocado pulp determine a decrease in the size of the ration and in the time eating, which can prolong the prandial act throughout the day. On the other hand, there are no notable differences between the Mexican Pelon pigs and the conventional or improved ones, as regards the indices of the food consumption pattern, less in the way in which they were determined in the present experiment.
