Effect On Using Plenty Of Unconventionality Feedstuff On Production Capability Of Fatten Pigs

The theme designed a breeding trial of fatten pigs which using plenty of unconventionality feedstuff instead of portion Of conventionality feedstuff. The trial investigated growing capability; nutrition absorptivity; blood index; immunity function; germ in feces; carcass characteristics and pork quality by using plenty of unconventionality feedstuff. We chose 90 healthy pigs, which had similar weights(P＞0.05) and 45-day lives. A group was using 8% unconventionality feedstuff during 30-60kg and 6% unconventionality feedstuff during 60-90kg. B group was using 10% unconventionality feedstuff during 30-60kg and 8% unconventionality feedstuff during 60-90kg. C group was comparison group. Every group had also divided into 3 groups with 10 pigs each. The contrast experiment indicated:(1)Daily weight gain of A and B groups had separately extremely marked depressed 14% and 26% compared to C group(P＜0.01). The rate between feed and weight of A and B groups had separately extremely marked increased 17% and 26% compared to C group(P＜0.01). Appetite on daily feedstuff of B group had marked depressed 7% compared to C group(P＜0.05).(2)In aspect of digest ratio of nutrition, digest ratio of Ca, P of A and B. groups had separately depressed 5% (P＜0.05),7% (P＜0.01) and 5% (P＜0.05),9% (P＜0.01) compared to C group. Digest ratio of protein of B groups had depressed 5% compared to C group (P＜0.05). Digest ratio of fattiness of A and B groups had separately increased 4% and 6% compared to C group(P＜0.05).(3)In aspect of body quality, loin-eye area and muscle rate of A and B groups had separately marked depressed 6%, 7%; 5%, 7% compared to C group (P＜0.05). Fattiness rate and fattiness thickness of A and B groups had separately extremely marked increased 22%; 29%; 9%, 15% compared to C group(P＜0.01). (4)In aspect of sense estimate, fragrance, flavor, tender pork index of A and B groups had separately depressed 6%, 8%; 6%, 7%; 5%, 6% compared to C group(P＜0.05). Flesh color index of A and B groups had separately depressed 18%, 21% compared to C group(P＜0.01)(5)In aspect of pork quality, Leu and Arg content had separately increased 9%, i5%; 14%, 15% (P＜0.05). Asp, Lys and Glu content had separately depressed12%, 13%; 10%, 13%; 6%, 8% (P＜0.05). ALA content had separately depressed32%, 35% (P＜0.01). C14:0 and C16:0 had separately increased 5%, 8%; 5%, 9% (P＜0.05). Ch content of A and B groups had separately increased 5% (P＜0.05) and 9%(P＜0.01).(6)In aspect of blood index, the content of T-BILI, TG, Ch, HDL-Ch of A and B groups had separately increased 21%, 36%; 40%, 60%; 30%, 51%; 35%, 48%(P＜0.01). The content of Ca+, K+ had separately depressed 19%, 29%; 30%, 32%(P＜0.01). The content of GPT and ALP had separately depressed6%, 7%; 5%, 7% (P＜0.05).(7)In aspect of immunity index, EaT and EACB index of A and B group had separately depressed 14%, 8%(P＜0.05) and 21%, 14%(P＜0.01). C3bR rate of B group had separately depressed 21% compared to C group(P＜0.05).(8)In aspect of economic benefit, feedstuff price of B group had depressed 4% compared to C group (P＜0.05). Pure benefit of A and B groups had separately depressed 20%(￥61), 30%(￥92) (P＜0.01).
