First, skinning season peeling season has little effect on young Rex rabbits, and it has a greater impact on adult rabbits and older rabbits. In general, the quality of winter skin is the best. Therefore, it is best to select the season of skin peeling for adult rabbits or aged rabbits in late fall or winter.
Second, slaughter age In general, the quality of adult rabbit skin is better than that of young rabbit skin and old rabbit skin. The skin of pre-young-aged rabbits of 4 months old was not plump enough, fetal wool faded, hair coarse velvet thin, plate quality was light, and the commodity value was not high. The skins of 5 to 6 months old young rabbits are thick, dense and lustrous, with strong plate quality, moderate thickness and best quality. Aged rabbit skin is thick and hard, rough, hairy, dull, dull and dull, with low commodity value, and the quality of fur is gradually decreasing with the increase of childbirth times.
Third, Germplasm Factors Germplasm factors are one of the key factors that determine the quality of rex rabbits. For example, genetic variability is not stable. In addition to appearance of heterochromia, variegated, stain, and ribbon are prone to appear in the hair of their offspring. , rust and hanging belly and other defects, feeding, management, feeding and management have a great impact on the quality of fur. Insufficient protein in feeds will often lead to short awns and cause a decrease in the strength of wool fibers; the lack of vitamins and trace elements will often cause the rex rabbits to be discolored, fragile, and even produce hair loss. In addition, malnutrition can often lead to restricted growth of rabbits, small size, resulting in the skin area does not meet the level requirements.
Fifth, improper processing of processing factors will often produce knife holes, suede, lack of materials, support boards and fractures, crumpled board, etc., seriously affect the quality of Rex rabbit fur. Knife holes are caused by improper slaughtering and peeling techniques; scratching the skin is not known as a "knife." The depth of the "knife" is less than that of the skin plate thickness 1/2, and the effect is more than 1/2. Holes may appear after the system is made.
Sixth, storage conditions Due to improper storage of fur, often appear Chenpi, smoke, bored, mildew, the central defect and other phenomena, seriously affecting the quality of fur.
VII. Gender Impact Gender has a significant effect on the quality of Rex rabbit fur under the same conditions. Male rabbits slaughtered from 4 to 5 months of age are generally thicker than female rabbits. The coat is thicker, the plush is more dilute, the plate quality is more relaxed, and the elasticity is lacking. Therefore, the fur quality of the male rabbit is worse than that of the female rabbit. However, the quality of the female rabbit fur obviously decreased with the increase in the number of childbirth times. The more childbirth times, the worse the quality of the fur.
The larger the individual size rabbit, the larger the area of ​​the skin and the higher the level of fur.
