(1) hay
Refers to grass or other green plants in the seed before the harvest before the harvest down, made by drying. As hay still maintain some green color, it is also known as green hay. The purpose of dried green fodder is mainly to preserve the effective nutrients in the green fodder and to facilitate access at any time. Green feed after drying, in addition to vitamin D increased, the majority of nutrients than silage loss. Reasonable modulation of hay, the dry matter loss of about 18% to 30%. The nutritive value of hay depends on the plant species, growth stage and modulation technology of the raw material. In the case of raw materials, hay made from legumes contains more crude protein. In terms of energy, there was no significant difference between the three types of hay made from legumes, gramineous and cereal crops, and its digestion was about 9.61 MPa / ten grams. However, excellent hay, digestible crude protein content should be more than 12%, digestion in 12.5 megawatts / kg or so. In the mountains timely harvesting marsh hay, mountain hay, forest hay, can be used to feed deer. Due to the diversity of mountain hay and swamp hay, are generally known as mountain weeds, including a large number of legumes, Compositae and other broad-leaved herb.
(2) draft blight feed
The plaque is a short staple and unspecified. The stalk is mainly composed of stems and leaves that have been left after threshing. The shells are fragments of chips falling off from the grains and a limited number of small or broken particles. Most agricultural areas have a considerable number of drafts that can be used as deer feed. Draft straw feed not only low nutritional value, low digestibility. According to the total dry matter, the crude fiber 28% to 48%, nitrogen-free extract of 40% to 50%, crude protein accounted for 3% to 8%, vitamin content is very small. The nutritional value of shell feed is generally higher than that of straw feed, soybean pod is the most representative, is a good roughage, the crude fiber content of 33% to 40%, nitrogen-free extract of 12% to 50% , Crude protein 5% to 10%.
(3) foliage feed
Most of the leaves of the trees (including leaves and autumn leaves) and their shoots and fruits can be used as deer feed and have higher nutrition. Leaves are easy to digest, not only for deer to maintain the feed, but also for the production of deer feed. Although the foliage is rough, but far better than straw and US shell feed. Its nutritio组成部分的起源、季节、地点、variety, modulation and different. The general leaves contain carotene is 110 ~ 250 mg / kg. Walnut leaves are rich in vitamin C, pine leaves contain a lot of carotene and vitamin C, vitamin E, vitamin D, cobalt and vitamin K, and rich in iron, drilling, zinc, calcium, phosphorus, manganese and so on Kind of elements. In the summer j leaves the highest crude protein content, about 36%; gradually decreased after the fall to winter can be reduced to 12%. In the deer industry commonly used foliage feed mainly from oak trees, Lespedeza. Trees, elm, willow, mulberry, poplar, birch and fruit trees, etc., the general leaves of dry matter contains 15% to 20% of the crude protein. Deciduous leaves are the main roughage of the deer in the mountainous area. Including large, small oak leaves, all kinds of fruit leaves and broadleaf miscellaneous leaves, etc., of which small oak leaves for deer feed the most extensive. The nutrient content of the high-quality deciduous leaves is still higher than that of the stalk, close to the hay-like feed, usually deciduous with the crude protein 10.3% -26 .3%, nitrogen-free extract 37.8% ~ 55.7%, crude fiber 16.6% ~ 35.2%, inorganic salt 4.9% ~ 10.3%, which is less calcium and less All kinds of vitamins. Deciduous feed contains more tannic acid substances, non-bacterial diarrhea antidiarrheal effect, but a large number of long-term feeding will affect the deer's normal digestive function.
