Effects of pineapple by-product on nutrient composition, digestion and diet efficient of fermented total mixed ratio in goats
This study aim to evaluate the effects of utlization pineapple by-product (PBP) replacing with 10% dry matter of fresh corn plant on nutrient composition, preservation, nutrient digestibility and nutrient efficiency of fermented total mixed ratio (FTMR) in the goats. The results show that, replacing 10% dry matter of fresh corn plant with PBP did not affect on nutrient composition during fermentation. pH of the FTMR was lower for the PBP diet comparing to the control diet. The mold appearance was later for the PBP diet compare to the control diet. The replacing PBP with corn plant did not affect on the DM and OM intake and digestibility, but it resulted in the higher protein digestibility in the goat comparing with those of the control diet. The PBP diet did not affect the rumen fermentation of the goats. The average daily gain of goat fed PBP FTMR was higher than that of goat fed control diet. In conclusion, replacing PBP with 10% corn plant in the FTMR did not affect on the nutrient composition, but prolong preservation time, increasing digestibility and feed efficiency on goats.
