The Exploitation And Application Of Green Feed Additive In Pigs

The piglets were allotted randomly to four groups. There were ten piglets weaned at 40d of age in group 1 or 2 or 3 or control group. The basel diets of these groups were supplemented with the green feed additives. Group 1 with propolish, group 2 with propolish and Penac-T, grpoup 3with Penac-T and control group was not. Feed experiment lasted for 122 days. The results were as follows:(1)The addition of the green feed additives significantly increased the average daily gains (P<0.05) and the ratios of feed to gain(P<0.05); (2) The green feed additives could increase the contents of serum protein and serum alkaline phosphatase(P<0.01) and reduce the contents of serum total lipid and urea nitrogen(P<0.01) and increase the activation of serum glutamic-pyruvic transaminase(P<0.05). (3) The green feed additives markedly increased the contents of essential amino acid(P<0.01) and C18:2(P<0.05); Improved meat color and muscle marbling but not increased the eye muscle area and not reduced the average back thickness(P>0.05) and significantly reduced the contents of meal choleterol(group2 and group3 : P<0.01; group1 : P<0.05 ). (4) The green feed additives could increase the economic return for the producers.
