Is the binary sow better in size or ternary in size

Don't raise a ...... as a sow

The ternary body shape is good relative to fattening pigs.

A binary sow and a Duroc cross is a ternary finisher.

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

The mating breeds are different.

1. Binary pigs: crosses or strains between two breeds to obtain hybrid breeds. (refers to the breed of Landrace boars crossed with large white sows).

2. Ternary pigs: The three breeds of hybrid pigs are obtained by crossing the two breeds of a generation of hybrid sows and then crossing them with the second breed. (On the basis of the excellent binary pigs, they are crossbred with other breeds to obtain pigs).

Advantages and disadvantages of binary and ternary pig fattening.

The difference between binary pigs and ternary pigs is as follows: mating breeds are different 1. Binary pigs: crosses or strains between two breeds to obtain hybrid breeds.

(refers to the breed of Landrace boars crossed with large white sows). 2. Ternary pigs: The three breeds of hybrid pigs are obtained by crossing the two breeds of a generation of hybrid sows and then crossing them with the second breed.

On the basis of the excellent Kai digging liquid of binary pigs, it is crossed with other breeds to obtain loose rock pigs).

The hybrid effect is different 1, binary pigs: the degree of heterozygosity is larger, the hybrid advantage is obvious, the long hand argument is faster, the fattening effect is good, the application is more extensive, and the requirements for breeding technology are low. 2. Three-yuan pig:

Make full use of the advantages of crossbreeding, improve the lean meat rate, and solve the contradiction of insufficient pigs of the original mother, which has high requirements for breeding technology. The main deficiency of ternary hybrid pigs is to combine the advantages of binary pig hybrid pigs and the advantages of terminal paternal parents, and the growth rate is relatively fast.

In the case of a grown binary sow, the ears are large and slightly tilted forward, the body is long, the limbs are long, the width of the back is medium, and the lower abdomen is slightly downward. Because the grown-up binary sow is a breed crossed by Landrace boars and large white sows, it has the advantages of high litter size and strong adaptability, and can also take advantage of the characteristics of fast growth, good fattening effect and high lean meat rate of excellent lean pigs to improve the lean meat rate of commercial pigs.

1. The physical appearance and characteristics of binary sows.

1. Features. In the case of the growing binary sow, which has large ears and slightly tilted forward, a long body and limbs, a medium width on the back, and a slightly downward lower abdomen, the 2 3 growing binary sow has the characteristics of the paternal system. Grown binary sows are breeds that are crossed between Landrace boars and Landrace sows, and the breed bred by crossbreeding between Landrace boars and Landrace sows is called Big Long Sow.

2. Advantages and characteristics of binary sows.

1) Binary sows combine the advantages of Landrace boars and large white sows, and at the same time have the advantages of strong adaptability and good motherhood, they can make full use of the characteristics of fast growth, good fattening effect and high lean meat rate of excellent lean pigs, and improve the lean meat rate of commercial pigs.

2) Binary sows have the characteristics of high litter size, easy delivery, low dystocia rate, high uniformity of piglets, tolerance to rough feeding, long service life and high litter size for life.

2. What is the difference between binary sows and ternary sows.

1. Different mating varieties.

1) Binary pig: a breed bred by the cross of two breeds or strains.

2) ternary pig: by three breeds of hybrid pig crossbred breed of breed, usually two breeds of crossbred to obtain a generation of hybrid sows and the third breed of pigs for crossbreeding, the production of hybrid pigs is called ternary pigs, the pig is based on the excellent basis of binary pigs and then crossed with other breeds to obtain the breed.

2. The hybridization effect is different.

1) Binary pigs: the degree of heterozygosity is larger, the hybrid advantage is obvious, the growth rate is faster, the fattening effect is good, the application is more extensive, and the binary pig has low requirements for breeding technology.

2) Ternary pigs: Ternary pigs make full use of the advantages of crossbreeding, improve the lean meat rate, and solve the contradiction of insufficient original sows, but they have high requirements for breeding technology, because ternary pigs combine the advantages of binary pigs and the advantages of the terminal paternal, so the growth rate is faster.
