Abstract: On the other hand, the animals weaned at 3 weeks were the heaviest at 9 weeks ( 20 kg versus 1 8.8 kg).The choc due to weaning was then largely compensated, but this was not the case for the animals weaned at 5 weeks.Total feed intake was higher in the animals weaned at 21 days ( 235 kg versus 19 8 kg feed/litter).Correlatively, the feed intake of the sows was lower for the same treatment ( 91 kg in the case of weaning at 3 weeks versus 1 66 kg at 5 weeks).The age at weaning had no effect on the fertility of the sows.From an economic point of view, feeding costs were slightly higher in the case of weaning at 3 weeks but this was compensated by a higher growth rate.Consequently, weaning at 21 days allows production of a greater number of piglets per sow and per year than weaning at 35 days (about 1 .5 piglets) without raising the feeding costs. SUMMARY PRACTICAL EFFECTIVENESS OF A NEUROI,EPTIC AGENT UPON WEANED PIGLETSTo study the effectiveness of a neuroleptic agent in alleviating the problems following the mixing and moving of weaned piglets from one piggery to another, a double blind clinical trial has been used with two different procedures i. e. either a short or a long lasting transport both occuring after the pigs were mixed, but before they entered the new piggery.
