【摘要】：本研究采用胃蛋白酶-胰蛋白酶兩步體外消化法來(lái)測(cè)定小麥、玉米、豆粕三種原料在不同粉碎粒度下粗蛋白質(zhì)的體外消化率,分析小麥替代玉米的可行性；并結(jié)合實(shí)際應(yīng)用,來(lái)考察全麥型日糧對(duì)生長(zhǎng)豬生長(zhǎng)的影響。將小麥、玉米、豆粕分別經(jīng)1.5mmm、2.0mmm、2.5mmm、3.0mm孔徑篩片粉碎,三種原料在4種不同粉碎粒度下分別各取3個(gè)樣品,采用體外消化法測(cè)定胃蛋白酶消化率和胃蛋白酶-胰蛋白酶總消化率,試驗(yàn)結(jié)果表明：在本實(shí)驗(yàn)條件下,相同粉碎粒度的小麥與豆粕的粗蛋白質(zhì)胃蛋白酶消化率和胃蛋白酶-胰蛋白酶總消化率差異不顯著(P0.05),小麥和豆粕與玉米的粗蛋白質(zhì)胃蛋白酶消化率和胃蛋白酶-胰蛋白酶總消化率差異均顯著(P0.05)；三種原料的粗蛋白質(zhì)胃蛋白酶消化率和胃蛋白酶-胰蛋白酶總消化率從高到底為豆粕小麥玉米。同種原料隨著粉碎篩片孔徑增大,粉碎粒度增加,粗蛋白質(zhì)胃蛋白酶消化率和胃蛋白酶-胰蛋白酶總消化率呈下降趨勢(shì)。選取150頭健康狀況良好、日齡相近,平均體重30kg左右的杜長(zhǎng)大仔豬,隨機(jī)分為2個(gè)處理組,每個(gè)處理組設(shè)5個(gè)重復(fù),每個(gè)重復(fù)15頭豬。兩個(gè)處理組分別飼喂小麥型日糧和玉米-豆粕型日糧,飼喂試驗(yàn)期共36天。試驗(yàn)結(jié)果表明：小麥型日糧組和玉米-豆粕型日糧組在日增重、采食量、料重比、腹瀉率等生產(chǎn)性能指標(biāo)方面均無(wú)顯著差異(P0.05)；在屠宰后胴體肉色方面也無(wú)顯著差異；但小麥型日糧在造肉成本上更有優(yōu)勢(shì),降低造肉成本5.01%,差異顯著(P0.05)。
[Abstract]:In this study, the in vitro digestibility of crude protein of wheat, corn and soybean meal was determined by pepsin and trypsin two-step digestion method, and the feasibility of wheat replacing corn was analyzed. The effects of whole wheat diet on the growth of growing pigs were investigated. Wheat, corn and soybean meal were crushed by 1.5 mm ~ 2. 0 mm ~ 2. 5 mm ~ 2. 5 mm ~ 2. 0 mm ~ 3 mm sieve respectively, and 3 samples were taken from each of the three kinds of raw materials under 4 different granularities. Pepsin digestibility and pepsin-trypsin total digestibility were determined by in vitro digestion. There was no significant difference in the digestibility of crude protein pepsin and pepsin-trypsin between wheat and soybean meal with the same granularity (P 0.05), but the digestibility of protein pepsin and pepsin in wheat, soybean meal and corn were not significant. The total digestibility of trypsin was significantly different from that of P0.05, and the total digestibility of CP pepsin and pepsin to trypsin were from high to high to soybean meal wheat and corn. The same raw material increased with the aperture of crushing sieve. The digestibility of crude protein pepsin and the total digestibility of pepsin and trypsin decreased with the increase of crushing granularity. 150 piglets with good health condition, similar day age and average body weight of about 30kg were selected. Two treatment groups were randomly divided into two groups, 5 replicates in each treatment group, and 15 pigs in each treatment group. The two treatment groups were fed wheat diet and corn-soybean meal diet, respectively. The trial period was 36 days. The results showed that the daily gain, feed intake and feed weight ratio of wheat type diet group and corn-soybean meal diet group were higher than those of wheat diet group. There was no significant difference in the production performance indexes such as diarrhea rate and carcass color after slaughter, but the wheat-type diet had more advantages in the cost of meat production, and reduced the cost of meat production by 5.01, the difference was significant (P 0.05).
