At present, the rural geese mainly use green roughage. The advantage of this type of rearing method is that it can save a large amount of concentrate feed and reduce the cost of feeding. The disadvantage is that the survival rate of the gosling is low due to the uniqueness of the feed, the growth and development are delayed, the disease is easy to be sick, and the slaughter period is prolonged, which is not suitable for large-scale feeding. In fact, according to the nutritional needs and digestive characteristics of goslings, the combination of fine green materials in the goslings stage, the growth rate of the goslings is accelerated, and the occurrence of various diseases is reduced. The survival rate is high, the slaughter is early, and the capital turnover is fast. Conducive to intensive production. The relevant technology is introduced as follows. Feed formula: Formula 1 (1--10 days old, %): corn 60, bean cake 15, bran 10, fish meal 5, grass powder 5, shell powder (bone meal, stone meal) 2, blood meal (silkworm cocoons) 1, sand 1, salt 0.4, antibiotics (feeding yeast preferred) 0.5, vitamin A powder 0.1, trace amounts of appropriate elements. Formula 2 (11--20 days old, %): corn (wheat) 40, bean cake 14, bran 26, wheat powder (powder) 4, fish meal 10, blood meal 2, shell powder (bone meal, stone meal) 2 , Salt 0.4, sand 1, vitamin A and vitamin D3 powder 0.1, antibiotic 0.5, trace element amount. Formula 3 (21--29 days old, %): corn 33, bean cake 15, bran 35, bad residue (corn starch residue) 5, bran (crack) 3, fish meal 5, blood meal 2, sand 1, salt 0.4, antibiotic 0.5, vitamin A and vitamin D3 powder 0.1. Since goose has two stomachs (including glandular stomach and musculature), and the cecum is very short, the general green feed emptying is only about 2 hours (hours). According to the digestive characteristics of the goslings, the nutrient concentration of the concentrate should be properly reduced when feeding the goslings, and the concentrates should be fed in small quantities. In addition, we can adopt the combination of feeding and grazing to make up for the lack of green feed intake during the brooding period. After a week of age, healthy goslings can be grazing at temperatures above 20°C, and should not be too far away from the pasture. It is advisable to have a near brooding room, and the grazing time should not be too long. It should be within 1 h (hours) at the beginning, and Grazing land must be fresh and the pasture must be leveled. The slope is less than 20 degrees (degrees). Generally, as long as non-toxic and non-odor grass goslings can feed, the goslings can gradually expand the range of pastures and extend the time of grazing, after multiple training exercises for the ability to eat grass. The physical quality of the goslings is enhanced, and a large amount of concentrated feed can be saved, which greatly reduces the cost of feeding.
