Abstract

This experiment was conducted to determine the digestibility of processed barley and corn grains in Turkmen horse by mobile nylon bag technique. Four Turkmen mares used in the experiment. Experimental cereals include barley and corn grains that used in four different forms include: Steam flaked, micronized, pelleted and without processing. The mobile bag filled with 1 g of one of experimental feeds and incubated through a nasogastric tube in gastrointestinal tract. Bags were collected from the faeces and after washing and drying the bags, dry matter, starch, crude protein and ether extract measured and digestibility coefficients calculated. Data were analyzed in complete randomized design with 2×4 factorial arrangement. The results showed that dry matter digestibility of barley was higher than corn (P<0.05), and also micronizing of cereals increased dry matter digestibility than other processing methods (P<0.05). Starch digestibility wasn't differ between two cereals, but micronizing and steam flaking increased starch digestibility than other processing methods (P<0.05). Individual comparison of processing effects showed increase in crude protein digestibility of pelleted corn (P<0.05). Digestibility of ether extract was higher in corn grain (P<0.05). In conclusion, micronizing and steam flaking can improve dry matter and starch digestibility in gastrointestinal tract of horses and processing have more effect on barley grain.
