The fattening period of the 28 brows is shorter, 10 to 14 Moon age, body weight 75 to 85 kg can be released; the pig can be slaughtered when the pig is 10 months old and weighs 50 to 60 kg. The daily gain during the finishing period was 458 grams and the lean meat rate was 43.2%. Eight eyebrow pig meat is good, bright red flesh, muscle was marbled, tender, fragrant, carcass lean meat protein containing 22.56%, eye muscle pH 6.71. Third, reproductive performance Boars are sexually mature and have sexual behavior around the age of 30 days. Boars began to be bred when they were 40 kg old at 10 months of age. The general life span is 6-8 years and there are as many as 10 years or more. The sows started estrus at 3- to 4-month-old (average 116 days).

Vegetable Seeds are used in the production of vegetable seeds, divided into conventional and hybrid seeds.Vegetables that conventional types of vegetables to grow itself through natural laws of seeds, vegetables hybrid seeds (general hybrid F1 generation of hybrid) is by using different features of plants (male and female parent) for their pollination, change its characteristics.
First, many varieties and complex.In science and technology is the first productive force and science and technology oriented market sense, such as policy, scientific research institutions, experts and scholars engaged in the work of agricultural breeding have mushroomed, new achievements and new varieties are created.The resulting problems, a species and strains are many, character difference is small, removing impurity harder when breeding, varieties of authenticity and purity is difficult to guarantee;Second, in many scientific research units and experts and scholars of breeding race, south guo is inevitable the sham as the genuine, some traits instability, poor adaptability, or no market with a production value of species, strain, misleading, interfere with the normal order of seed production and operation.So for buying vegetable seeds, should be on the basis of reputation good place.Buy formal cultivated seeds.
