The use of rabbits in mountain grasslands is a good way for the farmers to get rich. However, the rabbit's reproductive physiology has a different characteristic compared with pigs, cattle and other livestock: rabbits can not ovulate naturally during estrus, and ovulation is induced by mating stimuli. Without mating stimuli, mature eggs degenerate and shrink in the ovaries. When the female rabbits of the appropriate age are mated with the animals for a long period of time, degraded and atrophied eggs accumulate in the ovaries, causing early deterioration of ovarian function. Even too late breeding or two breeding intervals can lead to the same consequences.
Because the rabbit's breeding season is not seasonal. Females generally begin to return to heat on the second day after giving birth. In the absence of pregnant females, estrus occurs every 8 to 10 days for 3-5 days. Mating should be carried out during estrus. After mating, sperm can live in the female's reproductive tract for a day and night. The female rabbit starts ovulation approximately 10-12 hours after mating, and if the sperm and egg meet at this time, they will be fertilized. Rabbits are multi-fetal animals and have the ability to completely combine lactation and gestation. However, taking into account the health of female rabbits and the strength of pups, breeding rabbits at the appropriate age (7-8 months after birth) will be bred every year. Five litters are appropriate for farrowing.
According to practice, the greater the difference between the species and age of the female and male rabbits used for reproduction, the higher the conception rate of the female rabbits and the stronger the pups. The hybrids between the varieties have the characteristics of strong vitality, large body size, and rapid growth and development, as well as high feed utilization rate and strong disease resistance. Therefore, in the breeding of rabbits, the male and female rabbits of different breeds, ages, and ancestral origin should be selected for breeding. Each male rabbit can breed 3-4 times a day, but it is necessary to increase nutrition. The breeding time should be early morning or evening in the summer, and it should be done at noon in the winter. Mating time is best in the middle of the female estrus. Female rabbits have the following performances during estrus: mentally disturbed, loss of appetite or even deprivation of food, frequent grazing around, sometimes caged forage, and cry from time to time. When the vulva was examined, it was light red at the beginning, red and swollen in the middle, and later purple. When the female rabbit enters the mid-estrus phase, the female rabbit can be caught in a cage of rabbits to breed. If male rabbits catch and go to breed, it takes a long time to adapt to the new environment, so don't take the male rabbit to the female rabbit cage for breeding.
The estrous female rabbit usually mates with the male rabbit once to conceive, and if it is suspected that it cannot fit, the female rabbit can continue to be compounded in the male rabbit cage.
Starch sugar is the sugar produced by starch as the raw material and the enzyme preparation is widely used in the preduction of starch sugar. The enzyme method has unique advantages comparing with the traditional acid hydrolysis of starch. The enzymatic reaction can carry out efficiently under the conditions of normal temperature, normal pressure and mild acidity. Enzyme method can simplify production equipment, improve labor conditions and reduce cost. The enzyme itself is a protein and nontoxic. Enzyme is very sensitive to the pH value, and the reaction can be controlled by simply adjusting the acidity and alkalinity, changing the reaction temperature or adding inhibitors. The main liquefying enzyme is α-Amylase and the saccharifying enzymes include α-Amylase and Glucoamylase.
Sunson Starch Enzyme is developed for the hydrolysis of starch, we provide Glucoamylase, High-Temperature α-Amylase and Pullulanase for starch sugar industry.
Benefits:
Efficient degradation of dextrinsHigher dextrose yield
Less by-products formation
Low treatment costs and dosages
This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
