Data from table 1: compared with the pig fed with conventional feed, using being added with adding of 1 group of -2 group of the embodiment of the present invention Plus the growing and fattening pigs of the forage feed of agent, its fat percentage, percentage of water loss and storage losses rate are significantly lower than matched group, and cooked meat percentage, flesh Meat and lean meat percentage exceed matched group 7.38% and 12.66%, 0.47% and 1.31%, 9.83% and 12.5% respectively, so the present invention is real The pig feed additive that applying 1 group of -2 group of example provides can improve the carcass quality of pig.

Table 2 each group nutritive index synopsis

Nutritive index	1 group of embodiment	2 groups of embodiment	Matched group
				Moisture (%)	71.75	70.89	74.6
Protein (%)	21.4	23.7	18.5
				Intramuscular fat (%)	2.39	2.45	1.42
Cholesterol (mg/100g)	82.87	80.72	89.29

Knowable to the data of table 2: using the growing and fattening pigs of the forage feed of the feed additive being added with the embodiment of the present invention 1 and 2, The Carnis Sus domestica moisture of the growing and fattening pigs that the moisture of its Carnis Sus domestica is fed compared with conventional feed is low, and the pig of 1 group of -2 group of embodiment is described Meat water absorbing force is better than matched group, and the content of the Carnis Sus domestica of 1 group of -2 group of the embodiment protein than matched group is substantially much higher；Intramuscular Fat content determines the color of meat and the mouthfeel of meat, and the international criteria for classifying is 2.0%-2.9%, 1 group of -2 group of embodiment In machine, fat content is in critical field；Cholesterol is to lead to one of arch-criminal of numerous cardiovascular and cerebrovascular diseases, intake A lot of health risks, cholesterol in pork content 6.42% He lower than the Carnis Sus domestica of matched group of 1 group of -2 group of embodiment excessively can be faced 8.57%, meet lower cholesterol content standard.

By above-mentioned contrast experiment, it is added with the educating of the forage feed of feed additive of the embodiment of the present invention 1 and 2 Big porker, its carcass quality and nutritive index are superior to conventional feed, and are had been surprisingly found that by experiment, the embodiment of the present invention 1 He The feed additive of embodiment 2 can not only improve meat quality, and also to the lean meat percentage improving growing and fattening pigs, reducing lipidosiss has Significantly effect.

The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the spirit and principles in the present invention Within, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
