WYNIKI PRODUKCYJNE KRÓLIKÓW ŻYWIONYCH PODCZAS TUCZU MIESZANKĄ BEZ DODATKU KOKCYDIOSTAKTYKU
The objective of this study was to determine whether meat-type rabbits can be fed a diet without coccidiostatics during the fattening period. The effect of feeding two pelleted diets was compared during the experiment. The control diet was supplemented with the coccidiostatic drug robenidine, while the experimental diet contained no coccidiostatics. Over the experimental period the animals were weighed at 35, 56, 70, 77 and 90 days of age. Feces samples were taken for parasitological analysis and assayed for the presence of coccidia. Mortality rates were determined at particular stages of the experiment. It was found that a diet without the coccidiostatic drug had no statistically significant effect on the final body weights of rabbits. It was also demonstrated that coccidian infection rates and mortality rates were slightly higher in the experimental group.Badania miały na celu wykazanie możliwości żywienia królików mięsnych podczas tuczu mieszanką pełnoporcjową nie zawierającą kokcydiostatyku. W trakcie eksperymentu porównano wpływ żywienia mieszankami pełnoporcjowymi granulowanymi, z których kontrolna zawierała kokcydiostatyk – robenidynę a doświadczalna była go pozbawiona. Podczas badań zwierzęta ważono w 35, 56, 70, 77 i 90 dniu życia, ponadto z pod każdej klatki pobierano próbki kału do badań parazytologicznych na obecność kokcydii. Dodatkowo obliczono procent upadków królików podcza poszczególnych etapów trwania eksperymentu. Przeprowadzone badania pozwoliły na stwierdzenie, że brak kokcydiostatyku w mieszance nie wpłynął statystycznie na końcową masę ciała królików. Wykazano, że poziom
zarażenia kokcydiami i procent upadków był nieco wyższy w grupie doświadczalnej, jednak nie został potwierdzony statystycznie

BODY WEIGHT CHARACTERISTICS OF FARM-RAISED FALLOW DEER (DAMA DAMA L.) OVER THE WINTER PERIOD
The aim of this study was to determine the body weight characteristics of fallow deer fawns and does over the period from weaning to the time the animals are put out to pasture, as well as to analyze seasonal variations in their body weights during the winter months. Before the winter the average body weights of fawns, 1.5-year-old does and older does were 24.30 kg, 35.64 kg and 44.60 kg respectively. After the winter the average body weights were as follows: fawns that spent the winter with does in the wintering ground – 22.98 kg, fawns that spent the winter under a shelter
– 25.60 kg, does aged 1.5 years – 34.28 kg, does older than 2 years – 42.20 kg. It may be concluded that wintering under a shelter had a positive effect on the body weight gains of fawns
