First, choose to breed early fast-growing rabbit breeds. Judging from the current breeds of rabbits, there are mainly Belgian rabbits, French ram rabbits, giant German rabbits, New Zealand white rabbits, Japanese big white rabbits, American California rabbits and Danish white rabbits. These meat rabbits are large in size and can be slaughtered before 90 days of age.
Second, make full use of the advantages of hybridization to breed fine puppies. The puppies are the basis of meat rabbit breeding. To cultivate good son rabbits, we must choose the father and mother. The paternal breed rabbits require good meat quality, early weight gain, high feed conversion rate and high slaughter rate; maternal breed rabbits require more calving, good maternity, high milk power, strong feeding ability, and high survival rate and development of puppies . With such rabbit cross breeding, the laying pups are basically excellent.
Third, to maintain proper temperature and humidity in rabbit houses. The temperature and humidity in the rabbithouse have a certain influence on the weight gain of fattening rabbits. In the condition of intensive rearing, the optimal temperature for finishing the young rabbits is 24°C; the young rabbits' digestive enzyme system is fully formed at the age of 42 to 46 days, and the suitable temperature is 24~30°C; it enters 60~80 days of age. Take 18~24°C as well. The humidity in the rabbit house is not too dry because the rabbit prefers dryness and fear of moisture. Therefore, the suitable humidity for the rabbit house is 60%~65%, 60% is the best, the minimum can not be less than 40%, and the maximum can not be higher than 75%. Otherwise, it is unfavorable to fatten rabbits.
Fourth, often pay attention to ventilation and ventilation of rabbit houses. The accumulation of harmful gases in the rabbit house not only affects the growth and development of the rabbit, but also makes the rabbits sick. Ventilation conditions in the rabbit house are better to keep the rabbit house air clean and fresh.
5. Minimize lighting. Under the condition of feeding the full-price feed, fattening rabbits kept darkness in addition to adding water, adding ingredients, cleaning hygiene and observing health. In this way, it will not only save electricity, but also help increase the weight of fattening rabbits.
Six, timely slaughter. In terms of age, fattening rabbits are generally marketed for slaughter from 60 to 90 days of age. In terms of weight, it is appropriate to market slaughtered meat with a live weight of 2.25 to 3 kg. If the age or the live weight is too small, it will affect the income; if it is too big, it will increase the cost of feeding, which is very uneconomical.
Nucleic Acid (DNA/RNA) Extraction Kit
1. Introduction
The total viral nucleic acid extraction kit is suitable for extracting total viral nucleic acid from serum, plasma, tissue homogenate and other samples. The kit is based on silica column purification technology, which eliminates the need for toxic phenol-chloroform extraction and time-consuming alcohol precipitation. This product has successfully extracted nucleic acids from hepatitis B A/C, hepatitis C, and norovirus standard. The obtained DNA/RNA can be directly used in a series of downstream experiments such as PCR, RT-PCR, and LAMP.
Notice:
1. The carrier RNA solid must be dissolved in Nuclease Free Water to 1µg/µl before use, and vortex to dissolve. Store in aliquots at -70°C. If you need to store it at -20℃ for a long time, please repackage it according to the number of times of use.
2. Dissolve Proteinase K (20mg/ml): Add Proteinase Dissolve Buffer to dissolve Proteinase K to a final concentration of 20mg/ml. Proteinase K dry powder can be stored at 2-8°C for one year, but dissolved Proteinase K must be stored in aliquots at -20°C. Repeated freezing and thawing of Proteinase K can affect its activity.
3. Buffer VHB must be diluted with 14 ml absolute ethanol before use and stored at room temperature.
4. Buffer RW2 must be diluted with 80 ml of absolute ethanol before use and stored at room temperature.
3. Shelf life
Except for Proteinase K and Carrier RNA, other components of this product can be stored at room temperature (15-25°C) for 12 months, and should be stored at 2-8°C for long-term storage. Proteinase K and Carrier RNA dry powder are transported at room temperature. Please store at -20°C after receiving the test product, and store at -20°C after dissolving.
