The gilt is the basis of the farm. As the reserve force of the farm, its normal estrus and timely mating will affect the useful life of the breeder and ultimately affect the economic efficiency of the farm. There are many gilts on the farm that are still sexually mature and mature, and their proportion is not small (about 10%-15%), and even some gilts are eventually eliminated. Therefore, to ensure the normal estrus of gilts, we must grasp the two key control points that promote the normal estrus and timely breeding of gilts, that is, inducement and nutrition, which means that the two major management measures of “seduction management, nutrition management†must be In place. First, incentive management In many farms, gilts appear "not estrus," and more than 30% are "false estrus." Experiments have shown that when gilts reach 160-180 days of age, sexually mature boars are used for direct stimulation, and the initial period can be approximately 30 days in advance. In general, gilts that appear earlier in the puberty period have higher numbers of pregnancies and longer production periods. Therefore, gilts must pay attention to the incentive work. Suggested incentive schemes are as follows: 1. Grasp the first time of feelings: 170-190d, weighing 110kg. Do not induce prematureness, otherwise the gilt does not respond to boars and may be used to boars and does not stimulate estrus. 2, do a good job boar selection: more than 12 months of age, strong sexual desire, rogue, strong odor of the young boar. 3. Scientifically arrange contact frequency: 2-3 times daily, 5-10 minutes/time. 4, pay attention to the contact method: the best boar into the bar to induce, if you can not enter the column, but also to do nose contact. It is worth proposing that if the sows are still not estrus after 21 days of entice, they must strengthen the incentives. For example: grouping with estrus sows, carrying out proper exercise, restricting feeding, alternating with excellent feeding, etc. It is best to use a variety of incentives to better effect, such as: to strengthen the movement, change bar, parallel bar, boar contact and so on. Second, nutrition management 1, the use of reproductive nutrition with a suitable method of early initiation of the feelings of love, and the use of cellulose and intestinal nutrition methods to exercise intestinal function. 2, adjust the nutrition program in stages. When gilts reach 60kg, use reserved gilts for fast growth and do not limit feeding (before 100KG) before puberty. It is recommended that Hunan Jianong Zhenghe Biotechnology Co., Ltd. reproductive nutrition program, namely: 300g/t + 300g/t intestinal raw material or green feed or soluble fiber. 3. Special Note: 1 Do not use big pig feed at this stage, as gilts require 30-40% more reproductive nutrient than fattening pigs, some nutrients are even twice as high, and pigs are high in copper and lack choline. . 2 Back-up material can be fed until the birth of a child, which is beneficial to the reserve of key nutrition. Rapid test kits are designed for use where a preliminary screening test result is required and are especially useful in resource-limited settings.
• Same-day results provide timely treatment possibility.
[Test Principle]
Urobilinogen:Urobilinogen with diazonium salt produce red violet dyes in strong acid medium.
Bilirubin:The direct bilirubin with dichlorobenzene diazonium produce azo dyes in acid medium.
Ketone:The acetoacetic acid and sodium nitroprusside cause reaction in alkaline medium,which produces red violet compound.
Blood:Hemoglobin acts as peroxidase. It can cause peroxidase release neo-ecotypes oxide (O).(O) oxidizes the indicator and make the color change subsequently.
Protein:It is based on a specific pH indicator attracted by cation on protein molecule,the indicator further ionized and make the color change.This phenomenon is called protein-error-of -indicator principle.
Nitrite:Nitrite and aromatic amine are diazotized to form a diazonium compound.The diazonium compound reacts with tetrahydrobenzo(h)quinolin 3-phenol produce the red azo dye.
Leukocyte:Pyrrole amino acid ester produce free phenol under the hydrolysis of esterase in neutrophile granulocyte,the free phenol couple with phenyl diazonium salt produce purple azo dyes.
Glucose:The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.Peroxide hydrogen releases neo-ecotypes oxide(O)under the function of peroxidase.(O)oxidizes tetramethyl benzidine, which make the color change.
Specific Gravity:Methyl vinyl ether and maleic acid copolymer is weak acid (-COOH) exchanger,the M+ cation (the major is Na+) in urine reacts with the exchanger and release hydrogen ion,hydrogen ion reacts with indicator produce color change.
pH:The method of pH indicator is applied.
Ascorbic Acid:Ascorbic acid deoxidizes the 2.6-dichlorphenolindophenol dye into colorless in alkaline medium.
Microalbumin:Sulfone phthalein dye has high sensitivity to microalbumin by the method of protein error.
Creatinine:Creatinine with 3,5-Dinitrobenoic acid produce violet compound in alkaline medium.
Calcium:Calcium ion reacts with methyl bromothymol blue produce color change in alkaline medium.
