Baby pig castration is a procedure that is routinely conducted on male piglets in the European pig production. The presented trial has been conducted in a Hungarian large breeding unit. At an age of 3 days, there were two groups of baby pigs formed. Group one (n=678) has been castrated without anaesthesia, the animals of group two (n=678) has been castrated in ketamine and acepromacine general anaesthesia. The weight of the piglets has been measured on days 3.- 6.-, 10.-, 14.- und 28. At day 6 (the third day after castration) the piglets castrated in general anaesthesia showed significant (P<0.05) higher weights compared to the piglets castrated without general anaesthesia (2.75+/-0.69 kg vs. 3.22+/-0.37 kg). The significant differences (P<0.05) (4.23+/-0.51 kg vs. 4.74+/-0.45 kg) were still found at day 10 (7 days after castration). There were no significant differences detectable both at days 14 and 28. The authors suggest that castration in general anaesthesia has a positive impact on short term weight gain due to diminishing stressful events for the piglets, but exerts no effect on long term weight gain. Producers should be encouraged to castrate piglets in general anaesthesia.
While botanical composition, growth cycle and phenological stage are integral factors, they are not the sole determinants of the quality of grass silages from intensively managed permanent meadows.
Food that is unsuitable for human consumption does not affect the growth performance or carcass composition of pigs to which it is fed. This makes it a promising solution for reducing food waste.
Horses are ridden or driven on a variety of surfaces, which differently absorb the impact forces exerted on hooves, limbs and the horse's entire body. Objective measurement of the functional properties of equestrian arena surfaces is therefore of great importance.
