DEWORMING:
Must Read For All Pig Farmers going into 2025
Make sure you read to the end.👌
Worm burden can result in a loss of up to 15% in daily gain and 18% in feed conversion in growing/finishing pigs, increasing cost of production by 16 p/kg DW through increased food usage and reduced sale weight.
Large roundworms (Ascaris suum) are endoparasites which cause milk spot liver and are the most prevalent of worms affecting pig productivity and can cause sudden death if it's treated....
There can be up to 80 adult worms in the gut. These adults wil start producing eggs at a rate of 200,000-900,000 eggs per day in just over one month! This is why a low infection pressure can quickly lead to a NEW MASSIVE infestation.
Here are negative effects of not deworming.
NEGATIVE EFFECT OF NOT DEWORMING
Worm infections independently cause a great deal of damage.
The migration of roundworm larvae through the pig’s vital organs, such as the liver and lungs, causes a range of negative effects.
Secondly, adult worms feed in the intestines, thus, depriving the pig of nutrients. Consequently, the economic damage is a combination of inferior growth, increased feed conversion, the consequences of intestinal damage, lower lean meat percentage, condemned livers, increased medication cost due to increased health problems and higher mortality.
It is recommended that pigs kept for fattening, breeding or even kept as pets should be wormed against gastro-intestinal roundworms routinely. Pigs that are kept outdoors should also be treated against lungworms.
ROUTINE TREATMENT FOR PIGS
Routine treatment of adult pigs should be carried out every six months, and if possible either moved to clean pasture or their accommodation steam cleaned.
GROWING PIGS
Growing pigs should be treated at 8 wks then every 2 months until maturity.
SOWS AND GILTS
Sows and gilts should be treated 7-14 days before farrowing. Gilts should also be treated 7-14 days before going to the boar.
CHOOSING A WORMING TREATMENT
Before choosing a worming product it is good practice to determine the pigs approximate weight. This can be done by using a specially designed pig weigh band or by using the following calculation:
LENGTH (inches) X GIRTH (inches) / (medium) 11 = weight of pig in pounds (lbs)
Length – measured from between ears to top of tail whilst pig standing.
Girth – measured behind front legs.
The dividing factor of 11 should be used for medium pigs but should be increased to 12 for lean pigs or decreased to 10 for fat pigs.
The pigs weight in kilos can be determined by dividing the weight in pounds by 2.2.
