The pregnant sheep not only provides its own nutrition, but also meets the growth and development needs of the fetus in the abdomen. In addition, the water is cold and dry in winter, the temperature is low, and the light is low. There is less chance for the pregnant sheep to receive sunlight outside the pen home, and the body produces vitamin D. Also correspondingly reduced, if not timely supplement of calcium, phosphorus and vitamin D and other substances, pregnant sheep are susceptible to osteomalacia over winter, resulting in difficult labor in the future, postpartum expectorant, and fetal and umbilicated patients with congenital rickets, rickets, and even stillbirth. Winter breeding pregnant sheep should do the following: Strengthen care and increase lighting. It is necessary to repair the pens timely. The best choice for the pens is the leeward sunny place. In the cold weather, be careful to cover the plastic film and straw curtains outside the pens. The sheep pens should be diligently used for composting, constantly changing the soil, and keeping the pens clean and warm. For the sheep to drink warm soup, avoid feeding frozen grass and drinking water. In winter, there is less light, so we must seize the opportunity of noon sunshine and let the sheep go to the sun outside. Make full use of silage and ammoniated feed. The green corn stalks and sweet potato vines are chopped and shortened to make silage and ammoniated feeds for sheep. This not only saves concentrate feed and solves the problem of lack of winter feed, but also has good palatability and can meet the nutritional needs of pregnant sheep. With a reasonable mix of feed, add vitamins and calcium and phosphorus. In addition to diets such as silage for pregnant sheep, they should also be supplemented with substances containing vitamin D and calcium and phosphorus, such as fish meal, bone meal, eggshells, etc., as well as the storage of some cabbage leaves, carrots, oysters, sweet potatoes, etc. Vitamin feeds are short of nutrients to supplement straw feed. Preventive medications prevent problems before they occur. For lean pregnant sheep, it is necessary to take preventive medication as soon as possible to eliminate hidden dangers. The method is to feed calcium gluconate tablets that can be used together with cod liver oil pills to promote the body's absorption of calcium and phosphorus, and facilitate the deposition of calcium and phosphorus in sheep. In the bones. The medication time depends on the constitution of the pregnant sheep. Generally, it can be used continuously for 2 to 4 weeks.

Overwintering of pregnant sheep prevents osteomalacia
The evidence based guidelines shows that Anesthesia breathing circuit components can help to reduce infections,
prevent cross contamination between patients and maintain normothermia.
Why single-use circuits
• Respiratory pathogens can be transmitted through breathing circuits used to provide anesthesia. This can put
reusable circuits at risk for contamination of the next patient.
• The reuse of breathing circuits puts both patients and anesthesiologists at risk for hospital acquired infections.
Disposable circuits can be an important part of prevention protocol.
• The OR has unique infection control issues compared with other clinical care areas-due to the patient`s
vulnerability and prolonged period under anesthesia. Consequently, microorganisms may be transmitted via
contamination of normally sterile sites with a patient`s own bacteria and transmission of bacteria to subsequent
patients in the OR.
