3.1 All sheep should be kept in a leeward place, in a non-infectious environment, and in a place with convenient water sources. 3.2 Regularly prevent and treat diseases, and carry out epidemic prevention on the breeding list every year. 3.3 The breeding ram house, the production room, and the sheep breeding room should be disinfected regularly to eliminate the source of disease infection. 1
NY/T 677-2003
3.4 ​​According to the size of the sheep, set up adequate sheds and movable feeding cotton or hay racks to prevent crowding and uneven feeding of the flock. The activity range of the heat-producing sheep is 1.4m--2.3m. For high-producing mothers, it can be increased by 20~20%, and the range is 4.1m~6. (m. 3.5 Reasonable grouping, according to age, gender and lactation period, the strength and weakness of the sheep are scored. 3. Formulate a feeding and grass plan to ensure that there is a complete feed all year round: 3.7 Reasonable allocation of feed and grass, various growth stages need to be coordinated (see Appendix A and Appendix E). 3.B The feeding methods in different seasons vary, and the model type needs to be gradually replaced or the components in it need to be gradually increased or decreased. 3.9 According to the conditions of release, supplementary feeding or shed feeding should be carried out. Feed slowly and add less feed, first dry and then fine feed. 3.10 Feed cutting and adjustment, roughage should be chopped or shredded, and the shavings and pickles should be reasonably matched. 3.11 Anti-feeding method, various techniques, rates, cuts and grazing should be added appropriately in late autumn and winter, and exercise should be carefully added. Different types of sheep should be provided with different daily diets according to these feeding standards.
3.12 Clean water sources should be used to ensure sufficient drinking water for supplementary or shed feeding sheep. 4 Feeding techniques
4.1 Feeding and feeding techniques for sheep
4.1.1 The delivery room should be kept at a large size.
4.1.2 Disinfect the umbilical cord after delivery and the first-born ewes and the ewes and ewes that are not fertile. 4.1.3 After the cows are calved, they should be fed with colostrum in time. After living with the ewes in the pen for 2-3 days, they should be breastfed regularly every month, usually 1-4 times a day. The number of breastfeeding should be gradually reduced as the age of the ewes increases. 4.1.4 After the cows are calved for 1 week, high-quality dry food can be provided. As the weight and feed intake increase, the amount of milk replacer and concentrate can be increased. 4.1.5 From birth to 1 year old, the lambs should be fed with breast milk as the main food. For lambs with insufficient milk, they should be breastfed or supplemented with new feed. 4.1.6 Sheep can be taken out for exercise during the day and at night, but the herders should not go far away. In the late lactation period, the lambs should be fed with grass and fodder to adapt to the environment quickly:
4.1.7 The lambs should be fed with grass and fodder in the late lactation period, or the ewes should be kept in a water-conditioned environment. 4.2 Feeding and management techniques for growing sheep
4.2.1 The males and females should be divided into groups of different sizes. The small lambs should be carefully managed and supplemented. The grazing area should be selected with good grass quality. 4.2.2 The lambs are restless after weaning and are gregarious. The grazing system should be strict and strict to prevent them from running away. The grazing area should be kept away from the ewes. 4.2.3 The weaned lambs should be fed carefully and supplemented. Attention should be paid to supplementing the minerals in the intervals. According to the grass collection situation, the supplementation should be carried out according to the supplementation plan for mature sheep.
4.2.4 The sheep should be fed more intensively in the first wintering period. The standard of feeding should be adopted in an individual system or supplementation method. 4.3 Ewe feeding and management techniques
4.3.1 Make good pre-delivery preparations, such as leaving the shed, feeding, feeding mats, two-product tools, labor organization, clean the delivery room and thoroughly disinfect it. 4.3.2 Change the mats regularly after delivery and keep it very dry. 4.3.3 Do not let the ewes go too far away from the grazing area. Go out to pasture every day and return to feed once in the afternoon. 4.4 Empty ewe training and management techniques
4.4.1 In the usual feeding mode, empty ewes should be grazed more frequently and return less late. Use grassland forage to restore body condition, and feed grass and mineral supplements appropriately.
4. 4.2 For ewes bred in early autumn and winter, some supplementary feeding can be applied 2-3 days before mating to improve the acceptance rate. 4.5 Management techniques for pregnant ewes
2,5.1 Methods: Grazing and supplementation can be done before pregnancy. 4.5.2 Feeding management should be strengthened in the early stage of pregnancy, and the unfinished pasture or crop land should be fully utilized. The supplementation amount should be determined according to the climate and harvest conditions. The standard feeding standard for pregnant ewes should be adopted, mainly coarse feed, and fine feed should be appropriately matched. According to the quality of the feed, the proportion of fine feed and coarse feed should be adjusted according to the quality of the feed, and the exercise should be strengthened. 4.5.3 In the late stage of pregnancy, the standard feeding should be followed, and the fine feed and coarse feed should be increased to reach the standard amount. For ewes that are returned to the supplementary plan or released in small quantities with mainly feed, it is necessary to grasp the active and overall feeding amount. 4.6 Feeding and management techniques for lactating ewes
4.6.1 Laying ewes and non-laying ewes are raised in separate pens, and the feed is digested into high-quality green grass and sticky. Gradually increase the compound concentrate to reach the early lactation stage
4.6.2 For lactating ewes, give high-quality dry feed according to the supplementary standards, mixed concentrate and multi-line and green fodder. During this period, some nutrients need to be added to the energy consumption, etc.
4.6.3 The standard of raising sheep will be changed according to the feeding standards, combined with the feeding and grass conditions of each farm. No matter which shed or half-price ewes are located, ensure that there is sufficient clean natural water.
4.6.4 For double-covered ewes, the amount of feeding or supplementation should be more than 1= more than that of single ewes, and they should be managed separately from single ewes. 4.6.5 After the grass grows on the mountain, reduce or stop supplementing with new pasture areas. 4.7 Manage the relationship between rams and sheep according to the standard
4.7.1 Stop rams and single ewes from climbing and butting against each other, and deal with the damage in time. Check the roots of horns and bags in autumn to prevent parasitic insects and flies.
4.7.2 The males should be healthy, not obese, active, energetic and of good quality. 4.7.3 During the breeding period, the males should be selected and grazed in the single land. The appropriate amount of intercropping should be done. The males should be mixed with green grass and qualified feed to maintain the body condition.
4.7.4 During the breeding period, before the start of breeding, the males should be gradually given high-quality dry feed with high protein content. Ensure sufficient drinking water and good nutrition.
4.7.5 The males should be fed with more feed and grazed in the high-quality land. Common feeds include corn, soybeans, soybean cakes, etc. High-quality dry feeds such as lycopods, etc. Pay attention to the addition of calcium, phosphorus and other nutrients. 5 Management and control techniques during the shearing period
5.1 Make a good plan for shearing and prepare shearing machinery and tools. 5.2 The wool should be separated and packaged strictly according to the current management requirements of wool. 5.3. Shearing time: The climate in Hong Kong is very favorable. The wool should be sheared in advance, avoiding the time when cold air invades. Shearing should be done on rainy days to prevent the wool from getting damp and deteriorating. 5.4: Stop applying makeup and water 2-14 hours before shearing. 5.5: After shearing, the affected skin should be treated in time to avoid wound infection. 3. NY/T677-2003: See Table 4.1 for the standard of grass supplement for fine wool.
