If the production conditions are poor and the management level is low, it is best to use local breed sows to hybridize with the introduced breeds of Yorkshire and Landrace boars. The resulting hybrid sows have strong resistance, good adaptability, and easy management. Easy to raise, good litter performance, production levels will also have a greater increase. The disadvantage is that the lean meat rate and the growth rate are relatively poor.
For pig farms with better production conditions and better management, it is recommended to use the introduced variety, gram, as a female parent, and use Landrace boars as a parent to carry out crossbreeding. Conversely, it is also possible to use Landrace sows as a female parent and use Yorkshire as a parent. The male pigs are male parents, producing hybrid sows; regardless of the method used, the hybrid sows produced are pure-blood hybrid pigs. Such pigs have high growth rate, high lean meat ratio, and good feed compensation. The disadvantages are adaptability and The resistance is slightly poor and requires a high level of management.
The 5XZ-L laboratory Gravity Separator is used for separating seeds by specific gravity difference. It effectively separates granule with heavy specific gravity ( as gravel, soil particles), and granule with light specific gravity (as mildewed seeds, seeds damaged by worms).
Working principle:
The lab gravity separator sieve bed is triangular shape. On the sieve bed, there are more aluminum punching holes under the hopper area. This design will help raw material stratification.
By the effect of the sieve bed vibration and air blowing from bottom, the raw material is well separated to different ranks. The material discharge outlets are at one side. Outlets are for light impurity, mixing material, good seeds. There are flexible plates on outlets end. These plates can be adjusted to divide area then getting desired sorting effect.
Feature:
Laboratory Gravity Separator's sorting base on grain
density difference. The gravity separator table is triangular structure. The gravity separator table vertical angle, horizontal angle, vibration frequency,
bottom air blower volume are all adjustable. This can meet different dimension
/density seed sorting requirements. By
using the gravity separator, you will seeds density distribution of this batch
of seeds. It is an important seeds studying equipment.
