The main purpose of cross-breeding domestic pig breeds is to take advantage of the improvement in the performance of the descendants of the pigs above that of either parent. Crossbred pigs have some advantages over purebred pigs because of a genetic phenomenon called heterosis also known as hybrid vigor. Because of heterosis , most commercial swine producers use crossbred pigs rather than purebreds as market animals. To produce a good quality crossbreed pig, the parents of the hybrid pig must come from two different pure breeds.
For example, you can cross a pure breed female Hampshire and a pure breed male Duroc to produce an improved breed. A major objective of pure-breeding is to identify and propagate superior genes for use in commercial production primarily in crossbreeding programs as well as to propagate and identify superior females for maintaining valuable genetic material.
The table below contains some of the popular domestic pig breeds available for the pig farming business, with pictures. I know very little about pig farming and would like to learn, to be able to operate a medium-sized farm. And also, I am still waiting to pickup the meat from the pigs we just took to butcher and we are very anxious to see how they taste we took a red one, a blue dun and a blue and white so we are hoping to get some insight on which ones taste the best.
I have duroc x yorkshire hogs, both the boar and sow where the result of the mix. I sold the boar to e neighbor he was eating to much, but I still have the sow and she has had 2 litters of piglets.
Could single decaying tanker worsen global supply issues? HGV driver crisis: 'Things are not visibly getting better at this stage' industry bosses warn. It leaves farmers with the stark prospect of having to kill pigs which have been bred to eat and dump their carcasses.
UK employers are no longer able to recruit freely from Europe under post-Brexit immigration rules. Temporary visas that are being issued to workers in the poultry and haulage sectors to head off shortages in those industries have not been offered for pig processing. But Ms Davies, who first warned of the issue in August , said that even then they would need to be for longer than three months to attract the workers needed.
She described the despair being felt by farmers as worse than that experienced during previous disease outbreaks when large numbers of animals had to be killed - as there was no end in sight to the current impasse.
The shortage of food processing workers is just one element of a labour shortage taking its toll across the economy, with a shortage of , HGV drivers also causing havoc - most recently setting off a spate of panic buying at petrol stations.

Instead of raising a few animals in a small yard fed on food scraps or harvesting a few feral hogs from the mountain each fall, producers were now housing and feeding massive numbers of animals in confinement settings.
These pigs, like all animals and people, are more prone to health difficulties when forced into extreme proximity. With this, the use of prophylactic antibiotics, farrowing crates, and artificial insemination were developed to further increase efficiency and profit margins.
Another disadvantage to the centralized format of production was the large amount of waste generated. In fact these are still serious issues today within the business as evidenced by Smithfield Foods , who has recently been found guilty in court of causing harm to those who live in proximity to their hog rearing facilities. So here we find ourselves today, with a growing concern over antibiotics in our meat and calls for greater animal welfare. There seems to be a resurgence in folks who are interested in consuming heritage breed, pastured raised, humanly handled, pork products.
In other words, consumers are becoming more interested in small batch, non-industrial sources of pork for their consumptions.
Many experience sticker shock when we price out heritage pork from local farms. I often wonder how much of that differential is based on marketing and how much is based on the inefficiencies of smaller batch, slower growing, outdoor herds the topic is beyond the scope of this article. My hope is to work with local producers to keep the quality of pigs and pork high while bringing the price down to what most folks would consider affordable levels.
