Abstract

ABSTRACT A total of thirty sows (Landrace × Yorkshire) were used to determine the effects of plant protein source containing multienzyme on performance, nutrients digestibility and milk characteristics. A feeding trial was conducted for 21 days from parturition to weaning. Experimental diets were supplied for 1 week before the parturition day and throughout the experimental period. Dietary treatments included: 1) Control (CON; basal diet), 2) CGLT (included corn gluten) and 3) FSPM(included fermented soy protein containing multienzyme). Through the entire experimental period, backfat loss and return-to-estrus intervals were not affected by the treatments (P>0.05). Nitrogen digestibility was increased significantly (P<0.05) in FSPM treatment compared to CON treatment. Blood urea nitrogen (BUN) concentration was increased significantly (P<0.05) in FSPM treatment compared to CON treatment. At the initial period, total protein content of milk was higher significantly (P<0.05) in FSPM treatment compared to CGLT treatment and at the final period, total fat content of milk was higher significantly (P<0.05) in FM treatment compared to CON treatment. Rectal temperature showed similar tendency of change among treatments. The final piglet body weight, weight gain and ADG were higher significantly in FSPM treatment compared to CON treatment. On diarrhea rate in piglet, just one piglet occurred in CGLT treatement. In conclusion, 2.5% dietary plant protein source containing multienzyme suppelmentation improved N digestibility, BUN concentration, fat and protein contents in milk and weight gain in piglet.(
