At present, most developed countries feed rabbits with full-priced pellets, that is, as long as the pellet feed is used to ensure the supply of drinking water, the nutritional needs of rabbits can be met. However, this kind of feeding method has high cost and relatively low economic benefit, which does not meet China's current national conditions. Green feed has comprehensive nutrition and good palatability. It mainly uses green feed, and supplements with concentrate supplements can also meet the nutritional needs of rabbits. It can also improve the fur quality of rabbits, reduce feed costs, and increase economic efficiency. The general rural extension.

1 Materials and Methods

1.1 Test site

This experiment was conducted at the green feed base at the good breeding site of Taicang City Venus Rex Rabbit Co., Ltd., which owns 6.67 hectares of green fodder for rabbits.

1.2 Forage crop selection

In order to ensure the balanced supply and quality diversification of green feeds throughout the year, select forages with good palatability, rich nutrition, easy cultivation and high yield, such as ryegrass, bitter leeks, Mexican corn, sudan grass, carrots, kohlrabi, Alfalfa and so on.

1.3 Cultivation time

Various pasture cultivation time: ryegrass in late September, Sudan grass in early April, bitter leeks in late March, alfalfa in April-October, Mexican corn in April-May, and carrots in July-August.

2.3 Balanced round supply

The cultivation and utilization periods of the selected green fodder are different. As long as reasonable arrangements are made, a balanced annual round of supply can be achieved. The model is shown in Table 3.

From Table 3, it can be seen that there is a shortage of green feed in January-February and December of the year, which can be supplemented with vegetables or good-quality vegetable skins. In this way, a balanced supply of green feed can be achieved throughout the year.

3 Summary

3.1 Since the establishment of Jinxing Rex Rabbit Co., Ltd., it has been paying attention to the production of green fodder. Green fodder basically meets the needs of rabbits in the field. As green feed self-sufficiency, the entire production is implemented without pollution, so that the quality of green feed has been guaranteed, providing protection for the green breeding of rabbits.

3.2 From the practice of breeding shows that the selected green feed species for this experiment are more suitable for the rex rabbits, both grasses and legumes, as well as root crops (carrots). These pastures not only have good palatability but also have high nutritional value. And the output is also high. Adopting the "green material + supplement material" feeding mode not only reduces the cost of feeding, but also is beneficial to the growth and development of fur rabbits and the improvement of fur quality. During the breeding process of Venus Lexus rabbits, it has played an important role in satisfying the quality green feed supply. In December 2003, Venus Lex received unanimous approval from the Expert Group of the Rabbit Industry Branch of the China Animal Husbandry Association, and successfully passed the national first â€œAAAâ€ qualification certification for the breed of rabbit and the Jiangsu Science and Technology Department. The provincial scientific and technological achievements appraisal of "Green Farming Technology" also fully explained this issue.

Hair Removed Device:

IPL Hair Removal Machine is a kind of broad-spectrum visible light with a wavelength between 560 â€“ 1200 nm. According to the principle of photothermal effect, IPL can selectively act on hair follicles and hair rods rich in melanin granule cells to produce local micro-explosion and destroy hair follicle tissue, So as to achieve effective hair removal effect.
