Effects of non-starch polysaccharide enzyme on growth performance, carcass traits and meat quality of growing-finishing pigs
This study was conducted to investigate the effects of non-starch polysaccharide enzyme on growth performance,carcass traits and meat quality of growing-finishing pigs..Forty-eight Duroc× Landrace× Yorkshire crossed piglets with an average body weight of 40 kg were divided into 2 groups with 3 replicates of 8 piglets each,male:female was 1 ∶ 1,incuding:control group (fed basal diet) and experiment group(0.6％ non-starch polysaccharide enzyme in basal diet).The results showed as followed..(1) during the growth stage,the ADG and ADFI in the experiment group were significantly inproved and the F/G was decreased compared with the control group(P ＜0.05),ADG increasedby 9.8％,ADFI increased 4.7％ and F/G decreased by 5％ ; (2)in the carcass traits and nutrient component of the longissimus dorsi,the eye area muscle in the experiment group was significantly higher than that in the control group(P＜0.05),increased by 9.8％,the drip loss and the shear force in the experiment group was decreased compared with the control group(P＞0.05),decreased by 2.0％ and 14.6％.In conclusion,the results indicate that dietary non-starch polysaccharide enzyme can enhance growth performce and improve meat quality of pigs.
