    Pork Production Perspective: What’s New (and What Isn’t) by Kelly Klober in Farm Animals, Horses & Pets As consumer demand for pork raised in more natural ways increases, the groundwork laid by small-scale farmers of the past can guide tomorrow’s producers. Note: Outdoor production units or production units with outdoor exposure cannot always control bird, dog, cat, rodent, or wildlife access to pigs or feed. Depending on location, producers with outdoor facilities should be aware of the need to be more cautious and more observant.

Abstract "Issued March "--P. n of access: Internet Topics. Ultimately in commercial pork production, selection and crossbreeding are combined to achieve the highest level of performance.

An example of heterosis is a cross between Yorkshire and Landrace. Let’s assume that number of pigs born alive average 10 and 11 for Yorkshire and Landrace, respectively, and that daughters produced from this cross. The pigs marketed have high genetic potential for production and the sow herd has high merit for reproductive traits.

Ultimately in commercial pork production, selection and crossbreeding are combined to achieve the highest level of performance. Molecular genetics is also an important part of genetic improvement programs. The most common pig breeds for commercial pig production are the Yorkshire, Landrace, Hampshire, Duroc, and Tibetan, Tamworth and their crosses.

These breeds produce lean meat combined with efficient feed conversion (3 kg of good feed is needed to produce 1 kg of pork). A third breed (Breed C) may be added to this system. Known as a “three-breed rotational crossbreeding system”, the F1 female is mated to Breed C.

The resulting female progeny Crossbreeding programs for commercial pork production book as F2 or second filial generation) is bred to a boar from breed A, etc.

Inpork imports increased by 28 percent from the previous year to metric tons. The Duroc breed is commonly used in crossbreeding programs as a terminal sire to improve performance and meat quality in commercial pork production (McGloughlin et al.

; Whittemore and Kyriazakis ). Ultimately in commercial pork production, selection and crossbreeding are combined to achieve the highest level of performance. Gilts Selection Gilts of the appropriate genotype that have 12 to 14 teats should be selected from the sows with the best reproductive performance.

The genetic evaluation program typically used in the swine industry is referred to as: True. Sow productivity is the foundation of commercial pork production. False. The primary purpose of seedstock producers is to provide breeding stock Crossbreeding programs for commercial pork production book other seedstock producers.

True. The two basic types of swine crossbreeding systems are rotational. 1) sow productivity (number in litter/litter weight at 21 days), 2) growth weight, 3) feed efficiency, 4) carcass traits (pounds of acceptable-quality pork), 5) skeletal soundness ___________ in swine is widely used whereby the outstanding traits of 2+ breeds are combined and heterosis increases the pounds of market pigs sold per litter.

REFERENCES Ahlschwede W.T., Robison O.W., Allen P., Crossbreeding Systems for Commercial Pork Production, Pork industry handbook CD-ROM Edition. Success in commercial swine production is determined by a pork producer's ability to use resources efficiently.

However, the level of efficiency that can be obtained is set by the genetic merit of the breeding herd. The genetic merit of the breeding herd is established by the crossbreeding program used and the introduction of new seedstock either by purchasing females or most popular.

Pork Production Systems. Pigs breed at all times of the year so pork production is a continuous cycle. Traditionally, sows farrowed periodically, piglets were retained after weaning around eight weeks of age, grew slowly, and were consumed eventually or sold by their original owners.

Animal breeding - Animal breeding - Breeding systems: Crossbreeding involves the mating of animals from two breeds. Normally, breeds are chosen that have complementary traits that will enhance the offsprings’ economic value.

An example is the crossbreeding of Yorkshire and Duroc breeds of pigs. Yorkshires have acceptable rates of gain in muscle mass and produce large litters, and Durocs are.

It is generally the duroc boar that is used in commercial cross breeding programs with the Landrace / Large White sows.

The Duroc produces a heavy carcass and this cross works well for bacon production. For such a large breed, the litter size of the pure duroc sow is quite small and for this reason they are not used in commercial operations.

To remain competitive with alternative meat products, particularly pork and poultry, the beef industry must reduce cost of production and fat while maintaining tenderness and palatability of its products. Producers have two powerful breeding tools - systematic crossbreeding programs and composite populations - to assist in this tools offer the benefits of heterosis, breed differences.

The Creole pig was a result of centuries of inbreeding and possessed all the negative consequences of that breeding system, including low fertility, litter size, and growth rates, "Crossbreeding", practiced by 90% of U.S.

Pig Production Prestage’s vertically integrated production process affords a number of strategic advantages that allow us to be one of the most efficient pork producers in the United States.

The Chester White, which originated in Chester county, Pa., afteris restricted to the United States and Canada. The Berkshire, which originated in Berkshire, Eng., aboutis used for fresh pork production in England and Japan; a larger bacon type has been evolved in Australia and New the Duroc breed, the Berkshire is noted for the quality of its meat.

The United States is the world's third-largest producer and consumer of pork and pork products. In recent years, the United States has been either the world’s largest or second largest exporter of pork and pork products, with exports averaging over 20 percent of commercial pork production.

Introduction. Pork quality could be affected by the factors e.g., breed, animal nutrition, and pre-and post-slaughter managements.

However, breed could be attributed as to the most significant single factor influencing the meat quality traits (Josell et al., ).Crossbreeding is extensively used in pig production to increase the total efficiency of pig production and also to improve the.

One of the commercial breeds widely used in the KNP crossbreeding program is the Duroc pig resulting in KNPxDuroc crossbred (KNPxD). Duroc is usually used as a sire breed due to its higher feed intake, better feed conversion ratio (Raj et al., ), excellent growth rate that is important factor for fattening pig production (Suzuki et al.

Cows for a commercial operation can be bought at a purebred sale and then used in a crossbreeding program or you can contact individual producers to buy larger numbers of heifers that could be purebreds or crossbreds.

Another option is to buy animals through an auction barn. annually. Pork production and pig prices vary in a predictable manner during the calendar year. Such variation is called seasonality or seasonal variation.

The US exports billion pounds of pork annually, up 23% since and a % increase since the North American Free Trade Agreement (NAFTA) ofa treaty entered into by the US, Canada. Three are common in commercial pork production – Landrace, Large White and Duroc.

The remaining five breeds tend to be used by outdoor producers. Their popularity varies according to their commercial value – Tamworth, Wessex Saddleback, Hampshire, Berkshire and Large Black.

The identification of the origin and the authentication of food products are important issues to defend livestock production chains from frauds that produce consumer distrust and undermine commercial valorisation of many local and niche products (Montowska and Pospiech, ).Among these products, an increasing interest during the last few years has been directed to the.Breeding programs include pure breeding, linebreeding, outbreeding, grading up, and crossbreeding.

The pigs used in breeding programs are judged on such traits as growth rate, feed consumption, carcass quality, litter size, piglet weight, and thickness of back fat.

Domestic pigs reach market weight at about 5 to 11 months of age.
