硝呋烯腙对生长肥衣猪促生长效果试验 总被引:1,自引:0,他引:1
利用120头生长肥育猪,采用单因素试验设计,进行饲粮中添加硝呋烯腙(10mg/kg)、硝呋烯腙(10mg/kg) 金霉素(10mg/kg)、泰乐菌素(30mg/kg)和盐霉素(30mg/kg)对生长肥育猪增重速度和饲料利用效率影响的试验。结果表明,在30-60千克体重阶段,猪只的平均日增重分别为713g、742g、710g和696g(P>0.05);耗料增重比分别为2.62、2、63、2.64和2.59。在61-90千克体重阶段,猪只的平均日增重分别为894g、912g、887g和894g(P>0.05);耗料增重比分别为2.82、2.76、2.84和2.79。 相似文献

大蒜素对卡拉库尔羊日增重的影响 总被引:1,自引:0,他引:1
试验选用4-5月龄卡拉库尔羊12只,随机分为两组,即对照组和试验组,除饲喂常规日粮外,还在其精料中分别添加了0mg/kg和150mg/kg水平的大蒜素。结果对照组平均日增重为100.71g,而试验组平均日增重为-22.90g,说明大蒜素对绵羊无增重作用,在一定程度上还会抑制绵羊的生长。 相似文献

不同营养浓度对全舍饲山羊生长发育的影响 总被引:1,自引:1,他引:0
对40只6月龄的马头山羊和努马杂交羊分别予以250g、300g混合精料进行舍饲。结果在较高营养水平下,试验羊平均日增重由93.5g增至131.5g,提高40%,差异极显著。其中杂交羊日增重由82g增至152g,提高85.4%;而马头山羊仅由105g增至111g,提高5.7%,差异不显著。 相似文献

Problems related to feeding behavior in horses fall into three main categories: underconsumption, overconsumption, and abnormal consumption. Anorexia may be caused by a variety of diseases and overcome by removing the underlying causes (pain, fever), and physical or chemical stimulation of appetite. "Hypophagia" may be caused by poor dentition, disease, or stress. Again, removal of the cause or stimulation by physical or chemical means may improve intakes. Acute and chronic overconsumption of feeds are reflections of the normal controls (or lack thereof) of feeding in the horse. The only reliable prevention is to limit access to feeds. Abnormal eating behaviors such as pica or coprophagy are usually caused by a dietary imbalance or boredom. Coprophagey, however, is a normal behavior in young foals. Drinking disorders are rare, the only common one being the avoidance of "strange" water. Masking water at home with specific flavors such as peppermint or vinegar may encourage the horse to drink water from other sources to which the "home" flavor has been added. 相似文献

In the last decade there has been increasing emphasis on the role of healthy eating in the prevention of disease. The aim is to make people aware of the need to be more responsible for their own wellbeing. As attention is drawn to improving our diet there is now also greater awareness of the need to apply the same principles to our pets. I intend to discuss the key elements of dietary selection; nutrient content, energy, digestibility and palatability which are to be considered when formulating a healthy feeding regimen. Both physiological and environmental factors affect food intake and often animals' feeding habits will be affected by their owner. Finally, it must be remembered that cats and dogs are individuals and will always have their own particular food preferences. As long as a balanced diet is offered to the animals in sufficient quantities our pets should enjoy long and healthy lives. 相似文献
