【摘要】：本試驗(yàn)旨在探討飼糧添加亮氨酸和谷氨酸對(duì)肥育豬生長(zhǎng)性能、胴體性狀和肉品質(zhì)的影響。試驗(yàn)選取體重為77 kg左右的"杜×長(zhǎng)×大"肥育豬60頭,隨機(jī)分為5個(gè)組,每組12頭豬,公母各占1/2。對(duì)照組飼喂基礎(chǔ)飼糧,試驗(yàn)組分別在基礎(chǔ)飼糧中添加2.05%L-丙氨酸(等氮對(duì)照組)、1.00%亮氨酸+1.37%L-丙氨酸(亮氨酸組)、1.00%谷氨酸+1.44%L-丙氨酸(谷氨酸組)、1.00%亮氨酸+1.00%谷氨酸(亮氨酸+谷氨酸組)。試驗(yàn)期為60 d。結(jié)果表明:與對(duì)照組相比,谷氨酸組1~30 d的平均日采食量、末重和背膘厚均顯著降低(P0.05),31~60 d的平均日增重降低了22.50%(P0.05);亮氨酸組、亮氨酸+谷氨酸組背最長(zhǎng)肌和股二頭肌中的肌內(nèi)脂肪含量顯著增加(P0.05),且亮氨酸+谷氨酸組1~30 d的平均日增重增加了8.04%(P0.05),31~60 d的平均日增重則降低23.70%(P0.05)。與等氮對(duì)照組相比,亮氨酸組和谷氨酸組的熟肉率、滴水損失和肉色均無(wú)顯著差異(P0.05),亮氨酸+谷氨酸組肌肉黃度值顯著降低(P0.05);各試驗(yàn)組背最長(zhǎng)肌和股二頭肌中風(fēng)味氨基酸含量均無(wú)顯著差異(P0.05)。上述結(jié)果提示,飼糧添加1.00%亮氨酸可降低1~30 d肥育豬的料重比,增加背最長(zhǎng)肌肌內(nèi)脂肪含量;飼糧添加1.00%谷氨酸或1.00%亮氨酸+1.00%谷氨酸可增加1~30 d的平均日增重,降低31~60 d的平均日增重;飼糧添加1.00%亮氨酸+1.00%谷氨酸可降低肉色黃度值,增加肌內(nèi)脂肪含量,從而改善豬肉品質(zhì)。
[Abstract]:The purpose of this study was to investigate the effects of leucine and glutamate supplementation on growth performance, carcass traits and meat quality of fattening pigs. In this experiment, 60 "du 脳 Chang 脳 Da" finishing pigs weighing about 77 kg were randomly divided into 5 groups, 12 pigs in each group, male and female accounting for 1 / 2 / 2 respectively. The control group was fed with basic diet. In the trial group, 2.05 L- alanine was added to the basal diet with 1.00% leucine 1.37% leucine and 1.44% L-alanine (1.00% leucine and 1.00% leucine in the leucine group), and 1.00% leucine 1.00% glutamic acid group (leucine glutamate group) respectively. The experimental period is 60 days. The results showed that compared with the control group, the average daily intake, end weight and backfat thickness of the glutamic acid group were significantly lower than those of the control group, and the average daily gain of the glutamate group was significantly lower than that of the control group. The content of intramuscular fat in longissimus dorsi and biceps femoris increased significantly in leucine glutamate group, and the average daily gain in leucine glutamate group increased by 8.04 and 8.04g / kg for 30 days, while the average daily gain decreased by 23.70g / kg / d. The cooked meat rate of leucine group and glutamate group was higher than that of control group. There was no significant difference in drip loss and meat color, but there was no significant difference in the content of flavor amino acids in longissimus dorsi muscle and biceps femoris muscle in leucine glutamate group, but there was no significant difference in the content of flavor amino acids in longissimus dorsi muscle and biceps femoris muscle in leucine glutamate group. The results suggested that dietary supplementation of 1.00% leucine could decrease the feed weight ratio and increase the intramuscular fat content of longissimus dorsi, and 1.00% glutamic acid or 1.00% leucine 1.00% glutamic acid could increase the average daily gain of 1g / 30 days. Adding 1.00% leucine 1.00% glutamic acid to diet could decrease the color yellow value of meat and increase the content of intramuscular fat, thus improving the quality of pork.
