How to Identify Pig Diseases from Urination? Detailed Explanation of Deworming Methods for Sows

How to identify pig diseases from urination? How to deworm sows?

Parasitic diseases are a type of serious disease that harms pig production. Pig farms should pay attention to deworming sows to ensure the growth, development and health of sows. Generally, open sows and replacement gilts are dewormed once before mating by adding avermectin at 2 ppm to the feed and feeding continuously for 7 days. Deworming by oral administration of levamisole at 10 mg per kg of body weight also has good results. Pregnant sows should be dewormed twice from 2 to 6 weeks before farrowing, also by adding avermectin at 2 ppm to the feed and feeding continuously for 7 days, then after an interval of two weeks, feeding continuously for another 7 days. If ivermectin injection is used for subcutaneous injection in pigs, the deworming effect will be more pronounced than oral administration.

If disease occurs in the urinary system of pigs, pigs will show various abnormal manifestations or special symptoms during urination. By carefully observing the urination of pigs, the type of urinary system disease in pigs can be preliminarily distinguished. Several identification methods are introduced below.

Increased frequency of urination with a small amount of urine each time is pollakiuria, mostly seen in cystitis or bladder stones. Increased frequency of urination with a large amount of urine is polyuria, mostly seen in kidney disease and metabolic disorders.  Involuntary urination in pigs, manifested as urinary incontinence, is mostly seen in diseases of the spinal cord or central nervous system, as well as damage or paralysis of the bladder sphincter. Decreased frequency of urination with a small amount of urine is mostly seen in acute nephritis, severe dehydration of the body, or febrile diseases. Pigs often assume a urination posture but do not pass urine, mostly seen in bladder rupture, renal failure, or obstruction of the ureter, bladder or urethra. When pigs urinate, they arch their backs and strain, show pain, and even vocalize; this is difficult urination, mostly seen in cystitis, urethritis or incomplete urethral obstruction.

Newly excreted urine is white and turbid, and does not settle after standing; this mostly belongs to bacteriuria. If white flocculent sediment appears after standing, it is pyuria, mostly seen in urinary system infections or chlorpromazine, aminophylline, and piperazine poisoning. Urine is white, contains fine sand-like white matter, and often adheres to the hair at the urethral opening; this is a symptom of stones in the bladder.

Blood is mixed in the urine. If there is blood in the urine at the beginning of urination, but no blood in the middle and final segments of urination, it is often anterior urethritis; bright red urine is mostly urethral injury; blood in the final segment of urination is often acute cystitis or bladder stones; if there is blood throughout the entire urination process, it indicates that the bleeding site is in the upper urethra or bladder and kidneys; if hematuria is accompanied by colic, it is mostly seen in urinary system stones.
