USE OF THE MOBILE NYLON BAG TECHNIQUE FOR MEASURING IN SITU DIGESTIBILITY OF SOME SUPPLIES FOOD AND AVOCADO IN PIGS
The mobile nylon bag technique was used for measuring in situ digestibility of conventional feeds and avocado (Persea americana Mills) products in three 70 kg pigs fitted with a simple cannula in duodenum. One 3x3 Latin square was used for determining in situ digestibility of soybean, maize and sorg...
