配制日粮的原则是满足鹿对各种养分的需要,达到最佳或最高生产效益,充分利用当地饲料资源。主要考虑以下几方面:
Diets were formulated principle is to meet the need for various nutrients deer, optimum or maximum production efficiency and make full use of local feed resources. Mainly consider the following aspects:
一、根据不同性别、不同生物学时期的营养需要量或饲养标准,按规定的营养供给量进行配制。但也要考虑鹿群的体况、健康状况等适当增减,通过实际饲喂效果进行调整。
First, depending on gender, nutritional requirements of different standards or breeding biology period prescribed by the supply of nutrients formulated. But also consider appropriate changes in deer body condition, health status, adjusted by the effect of the actual feeding.
二、根据饲料的营养成分、饲料的营养特性及鹿的食性及消化性生理特点,合理选用饲料。注意饲料原料的质量及所含营养物质的差异。
Second, according to the nutritional content of feed, feed and nutritional characteristics of deer diet and digestive physiological characteristics, rational use of feed. Attention to the quality of feed ingredients and nutrients contained in the difference.
三、选用适口性好、消化率高的饲料进行配制。因为适口性的好坏,直接影响鹿的采食量。对于适口性差的饲料,要限制其用量。
Third, the choice of palatability, digestion rate of feed formulated. Because palatability will directly affect the amount of feed deer. For the poor palatability of feed, to limit their usage.
四、在配制日粮时,饲料的原料应多样化,尽量根据当地的饲料资源和现有的饲料种类,充分考虑各个原料的营养特点、适口性和价格因素等进行合理的搭配。发挥各种营养物质的互补作用。
Fourth, in the preparation of diets, feed raw materials should be diversified as much as possible according to local feed resources and existing feed categories, fully consider the nutritional characteristics of the various raw materials, palatability and price factors reasonable match. Play complementary roles of various nutrients.
五、注意各种饲料的理化特性,避免营养物质之间的破坏。不用霉烂、变质和有毒的饲料。
Pay attention to all kinds of physical and chemical characteristics of feed, to avoid the destruction of nutrients between. Not rotten, spoiled and toxic feed.
六、对当地土壤成分要有所了解,尤其是土壤中严重缺乏的元素对饲料成分产生的影响,如东北玉米往往硒的含量不足等。
Sixth, local soil composition to understand, especially the impact of a serious lack of soil elements to produce feed ingredients, such as the Northeast corn often insufficient content of selenium and the like.
