First, the economic value of planting grass and raising rabbits
1. Significant increase in income. Planting winter grazing 70 rye in winter and winter fields, the entire growth period of 5 to 6 months, harvest 3 to 4 times, per mu fresh produce 3 to 5 tons, equivalent to hay 600 to 800 kilograms. 200 rabbits can be raised per acre, and according to the market price, except for the production cost of grass seed, rabbit species and fertilizer, each rabbit can earn more than 10 yuan, and the net income per mu can increase by more than 1,500 yuan.
2. This section highlights synergies. Pasture can promote the growth and development of rabbits, improve the reproductive rate of rabbits and improve the quality of fur. Planting forages can be fed to rabbits in the green, and can also be processed into grass-flour mixes. The grass powder in condiments can account for 20%, which greatly reduces feed costs.
Second, the choice of pasture grass species
There should be three conditions: it should be a species of pasture that rabbits prefer to eat; adapt to local natural conditions and suitable for local production of planting conditions; with high yield and excellent quality.
Suitable for high quality pasture planted in our province, the rabbits like to eat the main Mexican corn, high Dancao, winter grazing 70 rye, annual ryegrass, bitter leeks, chicory and alfalfa and so on. These pastures feed rabbits have the following advantages: 1 high nutritional value. 2 use a long time. Annual pastures can be cut many times, and once perennial weeds can be used continuously for many years. 3 Fresh grass palatability is good. 4 Strong resistance to pests and diseases. These pastures generally do not cause serious diseases or insect pests, which can reduce production costs and reduce pesticide residues.
Third, it is worth promoting the production of grass and rabbit production model
1. The production mode of single pasture raising rabbits: In general, we should choose pasture varieties with large proportion of leaves, high quality and high yield to raise rabbits. The main production modes are as follows:
1 planting grass forage grass rabbit mode. The main choice is the cultivation of high-grass grasses such as Mexican corn, high-grass grass, sudan grass and sweet sorghum. Feeding rabbits directly as a green feed, the growth height is generally 80 to 120 centimeters, and it must be cut and used; when harvesting dry hay, The cutting height of the grass can reach 120-150 cm. Feeding a rabbit requires 18 kg grass (dried matter); feeding 100 rabbits, generally need to plant 2 to 3 acres of Mexican corn, or 2 to 3 acres of high Dan grass, or 3 to 4 acres of sweet sorghum and Sudan grass.
2 planting legume and forage rabbit mode. The main selection of leguminous grasses such as planted leeks and red bean grasses began in the budding stage with fresh grass feeding; or from the early flowering stage to the full flowering stage, drying hay to feed rabbits, each rabbit needs legume grass (dry matter) 20 kg; can also be processed into hay powder hay, added in the compound feed, the general proportion of grass powder added to the diet is 30% to 50%. Feeding 100 rabbits requires the planting of 4 to 5 mu of wolfberry or red bean grass.
3 planting leafy pasture rabbit mode. The grasses planted mainly include chicory, pine cone herb, bitter leeks, and grain pods, etc. It should be used as a green feed. The daily feeding amount can reach 50% to 60% of the ration, and each rabbit needs leafy vegetables. Forage (dry matter) 30 kg. Feeding 100 rabbits requires the cultivation of 1 to 1.5 mu of leafy pasture.
4 legume grass + gramineous grass mixed planting rabbit breeding mode. This model can improve the utilization rate of forage grass in rabbits; the commonly cultivated forage grasses include legumes, white clover, red clover, and red bean grass, and grasses are mainly perennial ryegrass, fescue, and cocksfoot. The ratio of leguminous pastures to forage grasses is 1:2 to 3. The proportion of rations that can be fed by green pasture when they are mixed can reach 70% to 80%. Feeding 100 rabbits requires an area of ​​6 to 8 mu for mixed legumes and grasses.
5 leaf grass + high stalk gramineous grass mixed rabbit breeding mode. The pasture varieties planted in this model include leaf lettuce, chicory, herb bitter leeks, grain pods, and grasses such as Mexican corn, Sorghum, Sudan grass, and sweet sorghum. These two types of pastures can be planted on the same plot, or they can be planted individually after harvest. The ratio of leafy vegetables to forage grasses is 2:3. The proportion of this mixed pasture in rabbit diets can reach 70. From 5% to 75%, feeding 100 rabbits requires an intercropping area of ​​2 to 3 acres of leafy pasture and high-grass forage grass, or 1 mu of leafy grass pasture and 1.5 acres of high-grass grass forage.
2. Pasture and food crops combined planting mode of production of pasturage rabbits:
1 wheat - pasture rotation. The cultivated pastures are mainly Mexican corn, grain pods and Sudan grass. After the wheat is harvested, these pastures are planted in wheat fields. After the end of September to the beginning of October, all the mowing is completed and wheat is sown to complete a rotation cycle.
2 Intercropping grasses in wheat reserve lines. In the middle and late May, pastures are planted in reserved rows of wheat fields. The cultivated pastures are mainly Mexican corn, Sorghum bicolor and Sudan grass. After wheat is harvested, it can be directly cut and utilized. These pastures are generally on-demand.
3 Maize - pasture rotation. After harvesting corn from the end of September to the beginning of October, the pastures are planted. The main planting species include Dongmu 70 rye and Lolium multiflorum. In the late May to early June of the following year, the winter grazing 70 rye is harvested and used to grow corn. . After winter grazing, 70 rye can be castrated to feed rabbits.
3. The mode of forage and rabbit breeding for pasture and fruit:
Grass and rabbits are planted under trees in our province, mainly mulberry gardens, orchards and ecological forests. This method can use the ecological, fodder and other conditions under the mulberry, orchard, and ecological forest trees, both economically and ecologically balanced.
When the saplings are small, grasses such as alfalfa, red bean grass, white clover, red clover, ryegrass, cocksfoot and chicory are planted between the rows of trees. In addition, branches, stems, stems and leaves obtained from tree pruning are collected and fed to rabbits. Raising the grass in mulberry gardens, orchards and ecological forests not only has convenient source of forage, but also has low cost and quick effect. The average monthly weight gain of meat rabbits can reach 500 grams or more; rabbit manure can also be collected and stored for fermentation. Trees provide quality fertilizer.
Wrist blood pressure monitors may be a great option for those looking for a compact and portable device to take blood pressure readings.
Wrist blood pressure monitors are very sensitive to body position and movement, and it is recommended that you keep your wrist at the level of your heart when taking your reading. For greater accuracy, sit up straight, rest your elbow on a table, and avoid unnecessary movements during readings.
