半胱胺及复合蛋白对肉牛生产性能和血液指标影响的研究
|
摘要
本试验分别在衡水格林、金泰来牛场进行，在肉牛日粮中分别添加不同剂量半胱胺和用不同剂量复合蛋白替代日粮中豆粕等蛋白饲料，研究其对肉牛生产性能、养分消化率和血液指标的影响。
试验一：选用西门塔尔杂交公牛64头，采用随机分组的设计方式，随机分为4组，每组16头，每组添加不同剂量半胱胺，分别为5、10、20、0g/头·天，研究对西杂公牛的生产性能、养分消化率以及血液指标的影响。
结果表明：(1)试验期间各组生长无不良状况，淘汰率为0；采食量正常，且各组间采食量无明显差异。(2)试验期试验1、2、3、对照组平均日增重分别为1065g、1025g、1217g、1052g，其中试验3组显著高于其它3组(P＜0.05)，试验1组比对照组略高，试验2组比对照组略低，但均差异不显著(P＞0.05)。各组粗料料肉比分别为12.37、13.42、11.21、12.63，精料料肉比分别为3.09、3.24、2.28、3.13，第3组明显低于其它各组(P＜0.01)，第1组显著低于2、对照组(P＜0.05)，2、对照组差异不显著。(3)血液指标中血糖(Glucose)和血清尿素氮(BUN)，试验3组与其它各组差异显著(P＜0.05)；3碘甲状腺原氨酸(T_3)和甲状腺素(T_4)，试验3组与对照组差异显著(P＜0.05)；胰岛素(INS)试验组与对照组差异不显著。试验3组生长激素(GH)、生长素介质(IGF-1)和生长抑素(SS)差异极显著于对照组(P＜0.01)。(4)粗蛋白消化率试验3组高于对照组且差异显著(P＜0.05)，粗脂肪消化率极显著高于对照组(P＜0.01)；中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)消化率各组差异不显著(P＞0.05)。(5)对照组(第四组)获利润2.55元，第三组获利润3.47元，比对照组净增36％，是对照组的1.36倍。
以上结果表明，在肉牛日粮中分别添加不同剂量半胱胺有利于提高肉牛生产性能，提高饲料利用率，增长经济效益。
试验二：选体重300kg左右西门塔尔等杂交公牛36头，随机分为三组，每组12头组间差异不显著。对照组使用牛场原有的预混料及其推荐配方，试验组使用复合蛋白替代饲料蛋白，比例分别为6％、10％。分别测定日增重、饲料转化率，血液指标，消化率并进行饲喂效益分析。
结果表明：(1)三个组的日增重分别为：对照组822g，试验一组839g，试验二组917g。试验一组和试验二组比对照组分别提高2.1％和11.6％。(2)料肉比试验组均低于对照组，且差异显著(P＜0.05)，试验一组和试验二组比对照组每单位增重耗料分别降低1.9％和10.4％。(3)血清总蛋白和葡萄糖水平，试验一组到对照组有增高的趋势，但差异不显著(P＞0.05)；血清尿素氮各组差异不显著(P＞0.05)。(4)养分消化率试验二组稍高，但差异不显著(P＞0.05)。(5)对照组每头每天获利1.44元，试验二组2.45元，增利1.01元，是对照组的1.71倍，饲喂净效益提高71％。
结果表明，不同剂量复合蛋白替代日粮中豆粕等蛋白饲料，如搭配合适，不但不降低肉牛生产性能，而且可以提高日增重，降低料肉比，增长经济效益，节约成本。
Our researches were conducted to test the effects of different dose of Cysteamine and compound protein instead of the proteins on production trait nutrient digest rate and blood index in beef cattle ,which were carried out hi Green of HengShui and Jin Tai.
In experiment 1:There were four groups,every group has sixteen male Simmentals which were selected at random from the total. Different dose of Cs, 5,10,20,and 0 gram per unit and per day for each group to determine the effects on performance , nutrient digest rate and blood parameters.
The result were followed (1) During experiment ,there was no any culling in any group and each group grow well; intake was normal, there was not significant difference; (2) The average weight of every group respectively increased 1065g,1025g,1217g,1052g every day. Obviously, the third group increased significantly than others(P<0.05),the first group increased slightly than the control group, the second group decreased slightly than the control group,but there was no significant difference among the four groups ( P>0.05 ).The rate of rough feed and beef of every group were 12.37,13.42,11.21 and 12.63 respectively, and the rate of fine feed and beef were 3.09,3.24,2.28,3.13 respectively. The rate of the third group was lower than other groups (P<0.01),and the first group was lower than the second and the fourth group (P<0.05). There was no significant different between the 2nd and the 4th group. (3) The content of Glucose and BUN was significant difference between the third group and the others (P<0.05);The content of T3 and T4was significant different between the third group and the control group (P<0.05);and there was no significant difference for INS between the treatment groups and the control group. The content of GH, IGF-I and SS was extreme different between the third group and the control group (P<0.01). (4) The content of the rate of CP was significant difference between the third group and the content group ,but the rate of digest of NDF ,ADF was no difference among the groups .(5) The profit of the third group was 3.47 Yuan which increased 36%than 2.55 Yuan the profit of the control group ,and was 1.36 times that the control group.
The results indicated supplementing CS in beef cattle can improve the performance of the beef cattle and improve utilization of the forage, it is benefit for improving the profits.
In experiment 2:Three groups of male Simmentals which was no significant difference were selected to determine the effects of supplemental 0%,6%,10% compound
protein on the weight the rate of translation of forage, blood parameters the rate of digest; then analysis the profits.
The result suggested:(1) The average weight per day of each group increased 8 22g,839g,917g respectively .The treatment groups improved 2.1%and 11.6%than the control group.(2) There was extreme difference from the rate of forage and beef (P <0.05), the consumption per unit of the treatment group decreased 1.9%and 10.4% respectively relative to the control group.(3) Serum total protein and glucose tended to increase but no significant difference(P>0.05); Serum urea-nitrogen was no signi ficant difference(P>0.05).(4) The nutrient the rate of digest of treatment group increa sed slightly, but 110 significant difference(P>0.05).(5) The profit per day per unit of the second group increased 1.01 Yuan than the control group.
The results indicated that different dose of compound protein can improve the
daily-increased weight and increase the profit.
