In swine production, the method of breeding piglets through crossbreeding between different breeds and strains using their heterosis is called economical crossbreeding of pigs. The general hybrid offspring have strong vitality, rapid growth and development, high daily weight gain, and the province's feed is welcomed by farmers. As a result, some farmers have reared piglets on their own pigs, but the piglets they produce have had more stillbirths, and their survival has become stagnant pigs. This is because hybrid pigs are produced by the crossing of two breeds with certain genetic differences. The hybrids are even genetically unstable. They are used as the offspring produced by their parents. Most of them are not developed to heterosis; They are closely related to each other and are used as maternity mates that are closely related to each other. Nuclear contradictions ease, genetic differences are small, and the viability is reduced. In addition, severe trait isolation occurs in hybrid pigs from the first generation. Therefore, the offspring produced by using hybrid pigs as breeding pigs are necessarily small in size, have weak viability, and have poor disease resistance. It can be seen that a new generation of hybrid pigs can only be reared for hogs, and they should all be castrated for fattening and cannot be used for breeding pigs.
Quick Release Pin
Quick Release Pins have a wide range of uses in fastening , locating , and alignment applications. The pins will not release until the button on the handle is depressed. Once the button is depressed, the balls retract into the shank allowing the pin to be inserted or removed into or out of a hole. The shanks are made from 304 or 17-4PH stainless steel. The handles for the pins listed below are made from aluminum alloy and anodized black. Stainless steel handles are also available .The pins are supplied with stainless steel split ring for attaching a cable assembly .Pins in other grip lengths are available as special orders .
The detent pins are designed to use in temporary quick disconnect operations. Used as a convenient way to adjust or remove accessories on equipment. The pin has a ball bearing on one end with a steel spring works that depresses and springs out to lock the pin into place.Rigid quality control procedures ensure a consistent fastener you can count on. Standard sizes are made from low carbon steel,zinc plated, or stainless steel.
