The early diagnosis of pregnancy is very important in dairy cows' production. Early diagnosis can be made to strengthen the feeding management and improve the milk production and the cow's constitution. At the same time, it can prevent miscarriage due to repeated breeding; if it is diagnosed as not pregnant, pay attention to it. One oestrus and timely breeding. However, the diagnosis of early pregnancy in cows is more complicated and difficult to grasp for rural cattle farmers. There is no detection equipment and reagents. Several easy-to-use early pregnancy diagnosis methods for cows are introduced for trial use by farmers.
Cervical mucus diagnosis
Take a corn-sized mucus at the cervix and place it in warm water. The water temperature is appropriate at 30°C~38°C. After 1-2 minutes, it is still not frozen but it is already pregnant. If you loosen it, it indicates that you are not pregnant.
Milk diagnostic method
1. Add 1 ml 3% copper sulphate solution to 0.5-1 ml of milk. The milk will condense into a pregnant woman.
2. Take 1 ml of milk into a test tube, add 1 ml of pure saturated sodium chloride, shake and then add 15 ml of 0.1% magnesia solution and shake for 20-25 seconds, then place it in boiling water for 1 minute and take it out for a rest 3 - Observed after 5 minutes, if the floc settled in the lower half shows that it is pregnant, floc formation is not formed or the upper part is not pregnant.
Urine diagnostic method
Take 20ml of urine discharged from the early morning of the cow into a test tube, add 1ml of vinegar first, and then add 1ml of 2%-3% medical iodine infusion, and then slowly heat and boil with fire. At this time, the top of the test tube is from top to bottom. A red color indicates pregnancy, such as light yellow, brownish green, and the color fades quickly after cooling and is not pregnant.
Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
