The Institute of Livestock Breeding in Dechang Township, Longdong City, Heilongjiang Province has proposed several typical types of pig rearing based on our survey of pig farmers in recent years, and analyzed and compared their advantages and disadvantages for reference and selection. (1) Professional rearing of finishing pigs This type refers to pig raising specialists to the piglet professional market or pig farms specializing in the production of weaned piglets for fattening till 90 to 100 kg for slaughter. The main advantages of this type: (1) The business is simple and easy to start, and it can be launched or discontinued at any time based on the fluctuation of market conditions. If you can grasp the pulse of the market, you can not only earn the profits of the pigs themselves, but also earn the difference. (2) The feeding cycle is short and the cash flow is fast. From input to output up to 3 to 4 months. (3) The fixed capital investment is small, and the column turns fast. Each block can be kept at least 3 batches per year. The main disadvantage of this type: (1) The supply of piglets is not stable, and it is difficult to buy piglets of the same breed, quality and specifications. (2) It is impossible to understand clearly the epidemic and immune status of the piglets, and it is easy to bring the disease to the field, posing a risk of disease. (3) Vulnerable to market fluctuations, the return varies with the market price of piglets and pigs. (2) Production and sales of weaned piglet This type refers to pig raising piglets that are raised by specialized pig raising households and sold to pig rearing households after the piglets are raised to a certain weight after weaning. (1) The turnover starts slowly. Once the breeding pigs are put into normal production, the cash flow is faster. (2) The intake and excretion of each pig is relatively small, and the daily physical input of the feed and excrement is relatively small. (3) Once the breeding herds are fixed, they rarely buy off-site pigs, and the chance of bringing in the disease from the outside is reduced, thus ensuring a good health status of the farm. The main drawback of this type: (1) Higher fixed capital investment. Not only will it be necessary to build a pregnant sow house, a nursing sow house and a piglet nursery, but also to spend a lot of money to buy a breeder. (2) The structure of the pig house is high. In particular, the delivery room, nursing sow house and nursery house need not only a more scientific structure of the pig house, but also facilities such as anti-heating and cooling, cold and warmth, and ventilation. (3) The profit per pig is smaller because the other part of the profit is distributed to the first type of finishing pig. (4) Breeding pigs and piglets have higher technical requirements, requiring both a higher number of live pigs and a litter weight, as well as a higher rate of rearing. (3) Feeding this type throughout the entire period refers to the whole process of production, management and management of raising pigs from pig production, piglet cultivation, and pig fattening until slaughter of 90 to 100 kilograms. It is the first type of pig raising and the second Joint of pig types. (1) The probability of purchasing pigs from the off-site is small, and the health of pig farms is guaranteed due to the reduced probability of the pigs being brought into the disease. (2) Earning piglets and fattening pigs in two parts, so the profit per pig is high. (3) Self-cultivation and balanced production. The main drawback of this type: (1) The turnover is slow. It takes at least 10 months from sow breeding to sale of fattened pigs, and therefore, there is no income for the first 10 months. (2) It is technically difficult to master the feeding and management techniques in all aspects. (3) The income changes due to fluctuations in the fattening market. (IV) Breeding of Breeding Breeders This is also a type of full-breeding. Its purpose is to produce breeding pigs and sell them to other pig breeders. Breeding pigs can either be pure or hybrid. This is a very specialized type of feeding. In particular, feeders need to have a good grasp of fattening technology, breeder lineage and strain development. (1) There is no uniform standard for the price of breeding pigs, which is often higher than the price of hogs. Fine varieties can sell very high prices and therefore have higher profits. (2) Has all the advantages of feeding all the way. (1) Because of the lack of heterosis, pigs produced from purebred pigs do not produce pigs from hybrid pigs, and thus the total number of pigs sold may be less. (2) Put more time and effort into saving pedigree and performance records. (3) Numerous other breeders in the market for breeding pigs visit the herds, which will bring disease risks. If the pig house has a short period of use, or if raising pigs is a temporary act, or if you can better grasp market conditions, choose the first type of pigs. If the breeder's expertise and technical advantages are for the rearing of sows and piglets, but the cash flow is insufficient, the second type of pigs can be selected. However, the economic benefits of raising piglets are relatively small, and they are also vulnerable to changes in market conditions. Therefore, the production and sale of piglets is not a good type of pig breeding, unless it is a good local breed with good motherhood, many litter size, and rough tolerance. Pigs, and green roughage rich in resources. Although the third type of pig raising requires relatively comprehensive pig-breeding technology and capital investment is relatively large, but the impact of market fluctuations and the risk of foreign diseases is relatively small, pig-raising income is relatively stable. If there is breeding technology, there is a strong sense of market and a large sales network. The fourth type is the most lucrative one.
Dried fruit products as the name suggests dried fruit products are fruits after selection, washing and other pretreatment, dehydration to the water content of 15 ~ 25% of the products. The volume and weight of dry fruit are about 11-31% and 10-25% of that of fresh fruit, so the cost of packing, storage and transportation can be saved significantly, and it is convenient to eat and carry. Dried fruit products take fruit as raw material, take natural drying or artificial drying (hot air drying, vacuum freeze drying, vacuum frying, etc.) methods to remove most of the water in the fruit group processing (pieces, pieces, grains, powder, etc.). Dried fruit products mainly include all kinds of dried fruit, crisp fruit chips, fruit powder, etc. Such as raisins, fruit chips, aromatic powder. Among them, dried fruit has raisins, dried apricot, edible coconut, dried apple, dried plum, dried pear, dried lychee, etc.
Dried fruit: this kind of products are dried fruit, dried products, such as raisins, dried apple, dried peach, dried apricot, red date, persimmon, persimmon pendant, etc. Dried Fruit Products,Freeze Dried Fruit,Best Dry Fruits,Mixed Dry Fruits XuChang Youjia Food Product Development Co., LTD , https://www.yjgrain.com
