How to distinguish between binary pigs and ternary pigs?

The first point can be seen from the shape of the ear.

The second point can be seen from the body size and body length.

The third point, judging from ** and fur.

Binary hybridization is the crossing between two varieties, and ternary hybridization is the crossing between three varieties. Farmers with good conditions can engage in "Sanyo" ternary hybridization, and those with general conditions can use "two oceans and one book", or "Sanyang one" ternary or quaternary hybridization.

Binary hybridization is also known as simple hybridization, that is, two varieties or strains are crossed to obtain a generation of hybrids. Due to the large degree of heterozygosity, there are obvious hybrid advantages, fast growth, and good fattening effect, so this kind of hybrid is widely used. The technical requirements are also simple.

A ternary cross is a cross of three varieties. It is to cross the two varieties to obtain a generation of hybrid sows into the upper body, as the second sow and then cross with the second breed of boar, called ternary crossbreeding. Ternary crosses generally work better than binary crosses and can make the most of a generation of crossbred sows.

Deng can make full use of the heterosis to improve the lean meat rate, and can solve the contradiction of insufficient original sows.

Binary pigs, three-dimensional pigs.

2 bucks for a pig and 3 bucks for a pig.

ok??

1. Different varieties.

One Yuan Pig is a hundred varieties of original pure products. Binary pigs are a cross between two breeds.

2. The advantages are different.

One-yuan pigs grow slowly and have poor fattening effect. Due to the large degree of heterozygosity, binary pigs have obvious hybrid advantages, fast growth and good fattening effect, and it is known that this kind of hybridization is widely used.

3. The technical requirements are different.

One-yuan pigs are purely naturally cultivated. The technical requirements for binary pig breeding are also simple.

The difference between one-yuan pigs and two-yuan pigs is: different breeds, different advantages, and different technical requirements.

First, the varieties are different.

1. One-yuan pig: it is a pure breed.

2. Binary pigs: a cross between two breeds.

Second, the advantages are different.

1. One-yuan pigs: slow growth and poor fattening effect.

2. Binary pigs: due to the large degree of heterozygosity, obvious hybrid advantages, fast growth and good fattening effect, this kind of hybrid is widely used.

Third, the technical requirements are different.

1. One-yuan pig: pure natural breeding.

2. Binary pigs: the technical requirements for breeding are also simple.

Binary sows, i.e. a generation of hybrid (grown or large sows) resulting from the crossbreeding of Landrace boars with large white sows or between large white boars and Landrace sows.

Binary sows bred to parents of different exotic breeds are called "exoduos". Exobinary sows refer to hybrid sows produced by crossbreeding between two imported breeds of pigs, such as the most common at present, Yorklands, Yorksgro, Duroc York, Duroc Landrace, etc. This kind of outer binary sow has the advantages of large size, high lean meat rate, moderate litter size, plump body, strong limbs, straight back and waist, no hooves and no belly, etc., in the case of better feeding conditions, there is a higher production performance and market price, and it is the basic sow group that most farms and farmers like to raise.

A monary pig is an ordinary, male and female offspring of a single line.

Monary is a purebred, and binary is the offspring of two purebreds.

When distinguishing between binary pigs and ternary pigs, the appearance characteristics of pigs can be observed, among which binary pigs are two interbreed hybrids with a body pattern and a small head, while ternary pigs are hybrids between three breeds, with droopy ears, large heads, heavy bones, and ternary pigs have no patterns.

How to distinguish between binary pigs and ternary pigs.

1. Distinguishing method.

If you want to distinguish between binary and ternary pigs, you can observe their appearance characteristics. Ternary pig refers to the successful crossbreeding of three breeds. With the Duroc pig as the male parent, the body shape is not patterned. A binary pig is a successful cross between two breeds with erect ears and a lighter head.

2. Binary pigs.

Binary pigs are breeds formed by binary crosses. It has obvious hybrid advantages, fast growth rate and good fattening effect. Moreover, binary pig crossbreeding is simple and widely used, and it is suitable for living in the whole country. It mainly feeds on coarse grains such as coarse grains, hogweed, etc.

3. Three-yuan pig.

There are three varieties of ternary pigs, which are the outer ternary and the inner ternary. The outer ternary is also known as the foreign ternary, which is the cross between the Duroc boar and the male parent. It has the advantages of fast growth rate and high feed utilization, and the alias of the inner ternary burner is soil ternary, which is usually formed by the cross of two foreign varieties.

4. Breeding methods.

When raising pigs, it is necessary to control the ambient temperature at about 16-18 degrees to provide a suitable growth environment for pigs, and ensure that the enclosure is ventilated and breathable to avoid a large number of bacteria in the environment. When raising pigs, pigs should be provided with barley, corn, wheat, sorghum, rice and other feeds to make them grow fast.

It is mainly manifested in the advantages of varieties.

Binary and ternary are divided into inner binary, ternary and outer binary and ternary.

Superior hybridization improves production performance: such as the number of births, lean meat rate, growth velocity, etc.

For example, domestic native pigs (high litter size, good motherhood) and Landrace or York (high lean meat rate, fast growth rate) are used as or closed paternal parents. The production is a binary pig, which has the advantages of both the male and female breeds.

If the mated binary pig is used as the female parent and Duroc or other pigs (good body shape, good meat quality) as the male parent, the crossbred is a ternary commercial pig, which has the advantages of three breeds of pigs at the same time.

The differences between binary pigs and ternary pigs are as follows:

Binary pig is a hybrid obtained by the crossbreeding of two breeds, with a large degree of hybridization, obvious hybrid advantages, and the advantages of fast growth and good fattening effect.

The ternary pig is a cross of three breeds, which is to cross the first generation of hybrid sows obtained by two crosses with the second breed of boars, and the hybrid effect is good, making full use of the advantages of a generation of hybrid sows, and solving the problem of insufficient original sows.

Pigs

Pigs, artiodactyl porcine mammals, native to Asia, Europe, Africa and other regions of the Old World. Pigs usually have large ears, long heads, short limbs, straight noses, fat bodies, and narrow backs. The coat is coarse and stiff, and the fur color is usually white, pink, black, brown and flower color.

Its classification is mainly domestic pigs and wild boars, domestic pigs are a subspecies of wild boars domesticated by humans, the tusks are shorter than wild boars, and they are one of the domestic animals domesticated by humans. Pigs are gifted with the genetic characteristics of arch soil, and foraging is a prominent feature of pig feeding behavior. The pig's nose is a highly developed organ, and the sense of smell plays a decisive role when foraging for food.

Although in the modern pig house, pigs also show the characteristics of arching foraging, each time the pig tries to occupy a favorable position in the trough when feeding the coarse food, sometimes the two forelimbs step on the trough to feed, if the trough is easy to approach, individual pigs even drill into the trough, stand in the corner of the trough, just like a wild boar arching the ground to feed, with the snout along the trough arch, the food is stirred out, and the wine is thrown to the ground.
