I have two barrows that were farrowed on July 12. One is growing fine, but his brother isn’t. He’s not just small…he is TINY!
About two months ago he wasn’t looking good…humped back, droopy tail, no enthusiasm for eating…and I wormed him with Ivomax, with a followup injection two weeks later. Everything improved…curly tail, level back, eating well, running and playing with the other pigs, eating with enthusiasm, shouldering in with others pushing to get to food…everything improved that is except…growth. He is getting taller (though he is not nearly as tall as his brother) but is still thin. Not emaciated thin, but his build is more of a dog than a pig.
What are the genetics???? These crosses???? What is the CI …. Was the mom feed Fescue???? Each pig will grow differently. We have those that grow long and thin putting on the stocky bulk at finishing. Others we have to watch they do not get fatty.
He may have been stunted by the illness or parasite load that he had earlier. Have you consulted with your veterinarian about possible continued illness or mineral deficiency?
He is only 4 months old and may have a growth spurt and catch up. Try weighing him on a bi-weekly (twice a week) schedule to gauge his rate of growth. If he is gaining consistently, then logically he would catch up to his sibling, but if he is not gaining consistently, then I would suspect a deeper illness or genetic issue. He may take longer to finish out as a meat pig.
