【摘要】：试验目的是为了考察初生仔猪口服营养液(简称营养液,下同)对乳仔猪死亡率和生长性能的影响。进行两个试验,试验一在未发生疫情时考察营养液对乳仔猪死亡率和生长性能的影响,试验设有两个处理组,对照组初生仔猪未灌服营养液,试验组出生仔猪每头灌服2 ml营养液。试验二考察在发生疫情情况下营养液对初生仔猪死亡率的影响,试验设有三个处理组,分别为对照组(吃初乳前未灌服营养液、发病后未灌服营养液)、试验组1[吃初乳前未灌服营养液、吃初乳后灌服营养液4 ml/(头·d),连用4 d]和试验组2(吃初乳前灌服营养液2 ml/头)。试验期均为30 d。试验结果表明:(1)未发生疫情情况下,与对照组相比,试验组提高成活率3.29%,ADG显著提高36.35%(P0.05)。(2)发生疫情时,对照组死亡率达到68.95%,而试验组1(发病后的仔猪连续灌服营养液)死亡率较对照组降低49.98%(P0.01),刚出生就灌服营养液的试验组2死亡率较对照组降低82.94%(P0.01),与试验组1相比,死亡率降低65.90%(P0.05)。结论表明:初生仔猪口服营养液显著降低死亡率,提高生长性能,可做为常规保健使用。
[Abstract]:The purpose of this study was to investigate the effects of oral nutrient solution on mortality and growth performance of newborn piglets. Two experiments were carried out. In experiment 1, the effects of nutrient solution on mortality and growth performance of piglets were investigated in the absence of epidemic situation. There were two treatment groups, the control group and the control group. Each piglet in the test group was given 2 ml nutrient solution. In the second experiment, the effect of nutrient solution on the mortality of newborn piglets was investigated under the condition of epidemic situation. There were three treatment groups in the experiment, namely the control group (no feeding before colostrum, no feeding after the onset of disease). Group 1 [before colostrum was not fed with nutrient solution, 4 ml/ after colostrum (head d), for 4 days] and test group 2 (before colostrum was administered with nutrient solution 2 ml/ head). The test period was 30 days. The results showed that: (1) compared with the control group, the survival rate of the experimental group increased by 36.35% (P0.05). (2), and the mortality of the control group reached 68.95%. The mortality of group 1 (continuous infusion of nutrient solution after onset) was 49.98% (P0.01) lower than that of control group (P0.01), and the mortality of group 2 was 82.94% (P0.01) lower than that of control group (P0.01). Compared with the trial group 1, the mortality rate was reduced by 65.90% (P0.05). The results showed that oral nutrition solution significantly reduced mortality and improved growth performance of newborn piglets, and could be used as routine health care.
