本研究选用6日龄AA商品代肉仔鸡200只,随机分为两组,用稻壳粉稀释日粮进行早期限食养分试验。以观察日粮稀释法对肉鸡生产性能的影响,结果显示:试验组鸡21日龄平均每只体重显著低于对照鸡(P<0.05),28、42、49日龄体重略高于相应的对照鸡,但无统计学上的显著性(P>0.05)。试验鸡6~21日龄段的饲料转化率显著低于对照鸡(P<0.05),21~28、28~42、42~49日齿段的饲料转化率优于相应的对照鸡。试验鸡每公斤增重所需饲料成本比对照鸡降低0.39元/公斤增重。  相似文献

试验将体重约10kg的35日龄断奶仔猪135头随机分成9组,通过添加豆粕、鱼粉、血浆蛋白粉3种不同蛋白源分别配制18%、20%、22%三个不同蛋白水平的日粮,研究蛋白源与蛋白水平对断奶仔猪生产性能与腹泻率的影响。结果表明:日粮蛋白含量超过20%时,仔猪腹泻率超过10%,其中蛋白含量20%和22%的豆粕组日粮腹泻率最高;但蛋白含量相同时,血浆蛋白粉组日粮腹泻率要低于鱼粉组日粮,鱼粉组日粮腹泻率低于豆粕组日粮。9个试验组中蛋白含量22%的豆粕组平均日增重最低;蛋白含量18%和20%的豆粕组、18%的鱼粉组日增重次之;血浆蛋白粉组及蛋白含量20%和22%的鱼粉组日增重最高,但18%、20%和22%血浆蛋白粉组之间日增重差异不显著(P〉0.05)。蛋白含量22%的豆粕组饲料转化率最高;血浆蛋白粉组、蛋白含量20%和22%的鱼粉组饲料转化率最低,但与血浆蛋白粉组的饲料转化率差异不显著(P〉0.05)。  相似文献

本研究选用18头28±1日龄断奶的杂交仔猪(平均体重约5.5kg),研究低蛋白质氨基酸平衡饲粮对早期断奶仔猪腹泻和生产性能的影响。试验结果显示:(1)低蛋白质氨基酸平衡饲粮使仔猪血浆挥发性盐基氨含量、血浆尿素氨含量和腹泻指数降低(P<0.05或0.01)。(2)采食全植物蛋白型氨基酸平衡饲粮(CP18.3%)的仔猪,其平均日增重(ADG)、平均日采食量(ADFI)和料肉比(P/G)与采食复合蛋白型对照饲粮(CP19.7%)的仔猪差异不显著(P>0.05),但前者的增重成本比后者降低(P<0.05)31%。(3)采食复合蛋白型氨基酸平衡饲粮(CP18.4%)的仔猪的生产性能优于采食复合蛋白型对照饲粮(CP19.7%)的仔猪,前者的ADG和ADFI分别提高(P<0.05)61%和32%,F/G和增重成本分别下降(P<0.05)24%和37%。(4)采食全植物蛋白型氨基酸平衡饲粮的仔猪,其ADG和ADFI低于(P<0.01)采食复合蛋白型氨基酸平衡饲粮的仔猪。前者的F/G和增重成本趋于高于后者,但差异不显著(P>0.05)。以上结果表明,低蛋白质氨基酸平衡饲粮可显著降低仔猪断奶后腹泻和提高仔猪生产性能。复合蛋白型?  相似文献

Amino acid (AA) levels in plasma and body growth were determined in rats (n20) fed diets with different soya bean meal levels. Free AA in plasma was determined by reversed-phase high-pressure liquid chromatography. We have used four levels of protein diets like 8%, 15%, 23% and 35% in this trial. Rats which were fed the low-protein (8%) diet with low percentage of soya bean meal were found to be growth-retarded. The body weight gain of high protein group (35%) was lower than that of the 23% groups. In the rats fed with the low-soya bean meal diet, some nonessential AA (NEAA) in plasma like asparagine, aspartic acid, cysteine, glutamic acid and serine increased, whereas the essential AA (EAA), with the exception of arginine, methionine and valine decreased. Here, plasma EAA-to-NEAA ratios were not correlated to growth and experimental diet. We hypothesize that AA metabolism is associated to changes in growth in rats on different protein intake. This study has showed the sensitivity of body mass gain, feed intake, feed conversion rate of rats to four levels of protein in the diet under controlled experimental conditions.  相似文献

A total of 32 weaner piglets (Landrace×Yorkshire) with an average initial body weight of 9.6±1.2 kg, and 29.8±2.7 days of age, were used in a 28-day growth assay to compare low-glycoalkaloid potato protein with fish meal as the main protein source. The piglets were housed pair-wise in pens and were fed semi-ad libitum. During feeding the piglets were separated allowing individual feeding within the pen. Four diets were tested with varying proportions of a high quality fish meal (F) and low-glycoalkaloid potato protein (P): diet A (10% F); diet B (5% F and 5% P); diet C (2.5% F and 7.5% P) and diet D (10% P). On average, in weeks 1–4, the piglets on diets C and D had higher feed intakes (17%; P<0.01) and daily weight gains (18%; P<0.05) than the piglets on diets A and B. There was no effect of diet (P>0.05) on feed conversion. It can be concluded from the present study that low-glycoalkaloid potato protein can completely replace high quality fish meal in diets for weaner pigs. The improved feed intake and daily gain with increasing inclusion suggests that low-glycoalkaloid potato protein may be superior to fish meal as a protein source for weaner pigs.  相似文献

By further experiment lasting 44 days trout fingerlings were fed with feed containing 50% poultry by-products meal in order to prove the possibility of using it as sole source of animal protein. Water temperature was 10-15 degrees C. The daily weight gain amounted to 2.17% with a feed conversion of 1.62 kg feed/kg gain. The control group being fed with standard feed (FB) containing 51.5% fish meal reached a daily weight gain of 2.33% with a feed conversion of 1.39 kg feed/kg gain. Due to higher lipid content of test diet the test group reached a higher fat content than the control group (10% compared to 5.9%). Suggested recipe makes it possible to use poultry by-products meal in pelleted feed for trout fingerlings.  相似文献

This experiment was to study the effects of corn germ meal in different levels on use value of finishing pigs.120 health PIC piglets aged 45 days with similar body weight (17±2.1)kg were randomly divided into 4 groups of 5 replicates for each group and 6 pigs for each replicates (male and female were the same in each replicate).Control group was fed basic diet,group one to three were fed diets containing different amounts of corn germ meal (5%,10% and 15%) with the same concentration of the main nutrient items.The results showed that compared with the control group,feed conversion rate in group one was no significant difference (P>0.05),feed conversion rate in group two had a significantly decreased (P<0.05),feed conversion rate in group three was significantly increased (P<0.05),average daily feed intake in control group was significantly lower than that in other groups (P<0.05),and there were no significant differences in daily feed intake among experimental groups (P>0.05).With the corn germ meal level increasing,the daily feed intake was increased slightly.Group one and group two had a tendency to reduce the serum urea nitrogen content,but group two had a significant difference (P<0.05),the content of serum urea nitrogen in group three was increased significantly (P<0.05),there were no significant differences in serum albumin,total protein and glucose levels among all groups (P>0.05). Compared with the control group,the apparent digestibility of crude protein and crude fiber in group one had no significant differences (P>0.05).The apparent digestibility of crude protein and crude fiber in group two increased significantly (P<0.05),and the apparent digestibility of crude protein and crude fiber in group three decreased significantly (P<0.05).There were no significant differences in the apparent digestibility of crude fat and crude ash compared with the control group (P>0.05).Theses results indicate that the best supplementation level of corn germ meal was 10%,the anti-nutritional factors of corn germ meal may be the cellulose.  相似文献

The aim of the experiment was to study the effect of pelleted and meal-form of a diet supplemented with lysine on passage rate through the digestive tract (DT) and utilization by young pigs. The experiment was carried out on 20 young boars of about 10 kg live weight, divided into 3 groups. The experimental diet composed of feeds of plant origin (barley 80.0%, sesame meal 10.6%, soybean meal 7.0%; total crude protein 15.3%) and supplemented with L-lysine to total level of 0.8% was fed twice daily as: a) a meal mixed with water (group I), b) dry meal (group II), c) pellets (group III). The experiment lasted 51 days including the last 6 days for nitrogen balance. On the first day of the collection period 3% Cr2O3 was included in the first meal to estimate the passage rate of feed. The average body weight at the end of the experiment was similar in group I and II (29.7 and 28.5 kg) but significantly lower as compared to group III (31.7 kg). Differences between the groups in the growth rate were higher during the first than the last period of the experiment. Pelleting reduced feed consumption per kg gain by about 12%. It was calculated that the increase in the live weight in group III could be attributed to the deposit of both protein and fat in the body. Large individual differences were observed in the rate of passage through DT and this probably effected the lack of significant differences between the groups.  相似文献

本试验旨在研究大豆肽和乳酸菌素对蛋鸡生产性能、蛋品质及血液生化指标的影响.选取336日龄健康罗曼商品蛋鸡576只,随机分成8组,每组3个重复,每个重复24只鸡.对照组饲喂基础饲粮,试验组分别饲喂在基础饲粮中添加0.075%、0.15%、0.3%大豆肽和0.1%、0.2%、0.4%乳酸菌素及0.15%大豆肽+0.2%乳酸菌素的试验饲粮.预试期1周,正试期4周.结果表明:1)饲粮中添加0.15%大豆肽或0.2%乳酸菌素均可显著提高蛋鸡产蛋率(P<0.01),降低料蛋比(P<0.05),显著提高哈夫单位(P<0.05),对平均日采食量、蛋壳厚度、蛋壳强度无显著影响(P>0.05).2)饲粮中添加0.15%大豆肽或0.2%乳酸菌素可以极显著或显著提高血浆谷草转氨酶(GOT) (P <0.01,P<0.05)、谷丙转氨酶(GPT)活性(P<0.01),降低血浆尿酸含量(P<0.01),对血浆总蛋白、清蛋白、球蛋白含量无显著影响(P>0.05).由此可见,饲粮中添加0.15%的大豆肽或0.2%的乳酸菌素均能提高蛋鸡生产性能和蛋品质,改善蛋白质代谢,并且0.15%大豆肽+0.2%乳酸菌素的联合应用优于单独添加大豆肽或乳酸菌素.  相似文献

试验采用单因子随机设计法,设4个不同的VE水平,每个水平3个重复。选取96只1日龄爱拔益加(AA)肉鸡,采用玉米—豆粕型基础饲粮,饲粮VE添加量分别为5、15、150及1 500 IU/kg。各处理间除VE水平不同外,其他营养及饲养管理条件均一致。试验期28 d,试验结束时,计算各组AA肉鸡的日采食量、日增重、料肉比、吞噬指数、免疫器官指数和新城疫抗体滴度。试验结果表明,当饲粮中的VE适当超量(150~1 500 IU/kg)供给时,可提高AA肉鸡新城疫抗体滴度、脾脏指数和法氏囊指数,但肉鸡生产性能下降。综合生产性能及免疫机能各项指标得出,1~28日龄AA肉鸡日粮中VE适宜添加水平为5 IU/kg。  相似文献

采用单因素完全随机设计,研究杂粕日粮中添加0.015%的酶制剂和0.15%的益生素与豆粕日粮饲喂蛋鸡的效果差异。结果表明,与豆粕相比,加酶或加益生素的杂粕日粮降低蛋鸡产蛋率、产蛋量、蛋重和蛋鸡采食量;通过添加益生素或酶制剂,杂粕日粮在饲料转化率上与豆粕日粮效果相当;与豆粕日粮相比,加酶或加益生素的杂粕日粮不影响蛋壳厚度和软破蛋率,也不影响能量和蛋白质代谢率,但显著降低排泄物中蛋白质含量。可见,一定程度上加酶或加益生素能可提高杂粕的利用率,但其实用效果与豆粕日粮还有一定差距。  相似文献
