Sažetak
Defficiency of the live stock food has been strongly felt in Macedonia in recent years. From the another side, development of canning industry and the remain of the secondary organic matters are a potential pollutant of rivers and the human environment. Taking into consideration that these matters have some energetic value and could be used in feeding animals (Jordanovski 1988; 1993), an experiment has been carried out on utilizing 5% and 10% of wild cherry pits, as substitue for corn in diets of fattening growing pigs. The experiment was performed with three groups: control and two experimental groups of 30 (15 m + 15 f) pigs in each group. The control group was fed with commercial mixture tho first experimental group with 5% of pits, and the second group with 10% of wild cherry pits. The experiment lasted 70 days. The initial live weight of pigs was 22.7 kg in all groups. At the end of fattening period the pigs of the second group were the heaviest (53.7 kg), and the lighest were the pigs of the second group (50.2 kg), while those of the control group weighed 53.0 kg. The differences are statistically significant (P<0,05). Total live gain is the highest in the first experimental group (31.0 kg) and the least in the second experimental group (27.4 kg), while in the control it is 30.3 kg. The differences are statistically significant (P<0,05). Total consumption of feed is almost the same in all groups ranging from 113.3 (control) to 115.3 (ll exp.) and 115.1 kg (1. exp. group). The gain/feed is most favourable in the first exp. group (3.71 kg), very close to this are the controls (3,74 kg), and rather low in the ll exp. group amounting lo 4.21 kg. According to the obtained rezults wild cherry, we can say that there is a possibility of utilizing pits in fattening growing pigs, because the results group do not diverge in the first exp. from the controls. They are even better and that means a cheaper production. However, the quantity of 10% of pits in the mixture seems much for fattening pigs.
