First, the care of newborn lambs. After the lamb is born, the body is weak, the adaptability is low, the resistance is poor, and it is easy to develop. Therefore, doing a good job of newborn lamb care is the key to ensuring its survival.
1, eat colostrum early. After the lamb is born, it usually takes more than 10 minutes to stand up and find the ewes' nipples. The first breastfeeding should be performed under the care of the confinement personnel so that the lamb can eat colostrum as soon as possible. Colostrum is the milk produced in the first week after delivery of ewes. It is rich in nutrients and antibodies and has anti-disease and laxative effects, which is beneficial to lambs excreting meconium.
2, early row meconium. Lamb meconid dark brown, sticky, usually 4 to 6 hours after birth can be discharged. If a newborn lamb blew and blamed, it might be meconium stagnation, if no meconium should be discharged after 24 hours, enema and other measures should be taken. Meconium is particularly viscous, easy to block the anus caused by defecation difficulties, should pay attention to wipe clean.
3, mother and child number. For management convenience and avoiding chaos on breastfeeding, mother and child numbering can be used, ie, the number of the ewe is written on the side of the lamb for identification.
4. Find a nanny sheep. Lambs develop rapidly during lactation. If the milk is not enough to eat, it will not only affect the development of the lamb, but also be easy to cause death. For the lack of milk, you should look for nanny sheep. The nanny sheep is usually the ewes who have lost their lambs or have extra milk. Otherwise, artificial breastfeeding should be performed.
5, artificial breastfeeding. Artificial nursing should first use goat milk, milk, milk powder, milk substitutes, etc. Artificial breast-feeding of lambs is an advanced method commonly used today in fat lamb production and dairy sheep production. The practice of artificial breastfeeding facilitates the formation of large-scale, factory-based production methods. When using artificial feeding methods to keep lambs, it is necessary to strictly control the composition and concentration of milk, especially when using milk powder and milk replacer, pay attention to hygiene and disinfection, must be determined when determining, quantitative, fixed temperature, to achieve standardized feeding management requirements.
Second, the identification of newborn lambs. The identification of newborn lambs is a preliminary selection of lambs (fine wool sheep, semi-fine wool sheep and their hybrids). Its role is to identify the quality of rams based on the rank composition of lambs, and the sooner the ram's descendant test results are known, the sooner they are known. The better; there are some traits (such as colored spots on the lamb and dog hair, etc.) can be clearly seen in the lamb, will gradually disappear after growing up or difficult to find, and these traits have a great impact on the quality of offspring.
The identification of newborn lambs should be carried out within 24 hours of birth. The items include type, physical fitness, physique, weight, wool and coat color. Type refers to the tendency of its product direction; constitution is based on the thickness of the bones, the width of the head and skin folds for the firm or thick, thin; physical refers to the size of the skeleton, can be combined with body weight assessment; body weight refers to its birth Body weight is represented by large, medium, and small. The weight of male lamb born at 4.5 kg or more is large, 3.5 to 4.4 kg is medium, and the weight of 3.4 kg or less is small; the hair quality can be divided into the same type of hair and basically the same type of hair and Mixed hair; coat color can be divided into white, body miscellaneous, miscellaneous head or all miscellaneous.
After identification according to the above items, the lambs can be divided into four grades: excellent, good, medium, and poor. Anybody with strong physique, large individual size, full white coat without hairs, good or slightly fine physique, large or medium sized body, white hair, same type or few canine hairs; strong or thick physique Small or medium-sized or slightly smaller, all white hair, same type, slightly larger dog hair, or medium-sized spots with minor spots on all four limbs; other items are slightly the same as above, but the main part of wool mixed or body has rough hair Or, the hair quality is slightly lower than the above levels and the body size is particularly small and the physical quality is particularly poor.
The above criteria apply to fine wool sheep and semi-fine wool lamb lambs and their hybrid lambs, but the hybrid lambs can be slightly relaxed on wool and coat color. The outstanding individuals selected through preliminary identification can use parent-subsidiary feeding management methods to strengthen cultivation and management.
Hearing Protection refers to devices used to protect the ear, either externally from elements such as cold, intrusion by water and other environmental conditions, debris, or specifically from noise. High levels of exposure to noise may result in noise-induced hearing loss. Measures to protect the ear are referred to as hearing protection, and devices for that purpose are called hearing protection devices. In the context of work, adequate hearing protection is that which reduces noise exposure to below 85DB over the course of an average work shift of eight hours.Different types of hearing protection may be utilized to maximize hearing protection. OSHA regulations dictate whether hearing protection is required and if the company must participate in a hearing conservation program.
