Pay attention to the reasonable amount of feed, can not completely replace the natural feed. The urea-fed cattle are better fed than the “microbes of cattle.†Urea can only replace the feed of a portion of the protein in the diet, and urea is the safest way to replace 20% of the total crude protein in the diet. In the urea diet, the crude protein content should account for 9% to 12% of the total dietary dry matter; carbohydrates are mainly starch, and cooked starch is better than raw starch, such as gelatinized starch urea. Do not feed urea alone to prevent urea poisoning. The reason is that cow rumen contains a urease, which can make the urea hydrolysis quickly, and the resulting ammonia will inhibit the microorganisms, at the same time, a large number of ammonia accumulation and into the blood, causing animal poisoning. To prevent poisoning, there are several points: 1 When feeding urea, add appropriate amount of heavy metal (cobalt or copper) or organic compound (acetate fatty acid) to inhibit urease activity. 2 Heat urea to convert it to biuret and feed it. 3 Soak the crude protein feed with 2% formaldehyde solution for 24 hours and feed it with urea. 4 Reasonable use of VB12, cobalt, sulfur and other trace elements. It is scientific to feed urea, but it is not appropriate to feed four cows. One should not be fed alone, should use good quality urea mixed with fine material or grass powder feed; second should not be fed postpartum cows, calves; three should not be mixed with raw bean cake or raw beans, should not be in the state of starvation Feed immediately; four should not give enough time, you should control the amount of feed, fed in batches, and extend the feeding time.

Sulfonamides are broad-spectrum bacteriostatic agents, similar to p-aminobenzoic acid (PABA) in structure. They can compete with PABA to act on difolate synthase in bacteria, so as to prevent the process of synthesizing folic acid required by bacteria as raw material and reduce the amount of tetrahydrofolate with metabolic activity. The latter is the synthesis of purine, thymidine and deoxyribonucleic acid (DNA) by bacteria Therefore, it inhibits the growth and reproduction of bacteria. The effect of sulfonamides can be antagonized by PABA and its derivatives (procaine and tetracaine). In addition, the presence of pus and tissue decomposition products also plays an antagonistic role, because it can provide essential substances for bacterial growth.
Description of use
An antibacterial sulfonamide; Induction of CYP3A4 expression and acetylation by N-acetyltransferase; It shows sex dependent pharmacokinetics and produces metabolic changes through male specific isomer CYP2C11; Inhibit dihydrofolate synthase to hinder folate synthesis. Equivalent to sulfadiazine. It is suitable for the treatment of hemolytic streptococcus, meningococcus, pneumococcus and other infectious diseases with long-lasting effect.
It is used as feed additive to prevent and control the infection of Staphylococcus and hemolytic streptococcus, that is, it is mainly used to treat avian cholera, avian typhoid, chicken coccidiosis, etc.
It is used to prevent the infection of Staphylococcus and soluble Streptococcus, inhibit hemolytic streptococcus and pleurisy coccus, and mainly treat avian cholera, avian typhoid, chicken coccidiosis, etc
It is used as an antibacterial agent to prevent and treat the infection of Staphylococcus and hemolytic streptococcus. It is suitable for the treatment of hemolytic streptococcus, meningococcus, pneumococcus and other infections. It is mainly used to treat avian cholera, avian typhoid fever, chicken coccidiosis, etc.
Sulfamethazine is a traditional antibacterial and anticoccidial drug. It has been widely used in coccidiosis of livestock and poultry in China. The anti coccidia mechanism and peak period of sulfamethazine are the same as Sulfaquinoxaline.
purpose
â‘´ the effect of poultry sulfamethazine on chicken coccidia is the same as that of Sulfaquinoxaline, that is, it is more effective on chicken small intestinal coccidia than cecal coccidia. If you want to control cecal coccidia, you must use high concentration drugs.
Sulfamethazine also does not affect the host's immunity to coccidia. In addition, its antibacterial activity is stronger than Sulfaquinoxaline. Therefore, it is more suitable for coccidia complicated infection.
Coccidia turkeyi can be administered with sodium salt drinking water at a daily dose of 110 ~ 290mg per kilogram of body weight.
(2) for other rabbit coccidiosis, 0.5% medicine can be used for one week, and it can be used for another week after stopping the medicine for one week, or it can be fed for three days according to the daily dose of 109mg / kg body weight. For prevention, o.1% medicine can be used continuously for 2 ~ 4 weeks.
Mink and other coccidiosis can be taken orally at the concentration of 0.5%.
It is effective to treat Eimeria bovis and Eimeria Qiu infection in calves with 5g per 45kg body weight for 5 days.
Lamb coccidiosis can be treated with 0.4% medicine or 0.1% sodium salt for 7 ~ 9 days.
Use attention
(1) long term continuous feeding of sulfamethazine can cause serious toxic reactions. If it is fed at the concentration of 0.5% for 8 days, it will cause hemorrhagic infarction and swelling of spleen in chicks. Continuous feeding at 1% concentration for 3 days can significantly affect weight gain, prolong hemagglutination time and even bleeding lesions due to obstruction of intestinal vitamin K synthesis. Therefore, intermittent dosing method should be used for this product.
(2) laying hens are forbidden.
(3) the rest period is 5 days for broilers, 10 days for turkeys and 11 days for beef cattle.
