Abstract
Short-term tests of feed intake pattern were conducted with 20 growing pigs of 41 kg liveweight fed with isoproteic diets containing either untreated or treated canavalia and velvet beans (25% of the diet). Experimental diets were compared to a control, soyabean formulated diet. Data of feed intake were compareded within every day and within every offered feed interval according to a one way classification. A paired data test was used to compare feed intake amongst different days. Feed intake significantly decreased (P0.01) when the animals ate diets containing untreated beans. There was no dispersion in feed intake data either 4 hr after the ingestion of treated velvet bean or 16 hr after start eating treated canavalia beans. There was no improvement in feed consumption of a diet containing fermented canavalia beans, but beans soaking with calcium hydroxide caused an effective increase in pig's feed intake. The pattern of feed intake could be described by curves ajusted by regression analysis. It is suggested that the short-term test of feed intake in pigs is appropiate to readily obtain results with low levels of inclusion in the strategy of searching locally available fe resources for pigs.
