RAPESEED OIL CAKE IN FATTENING HYBRID GEESE

Pogača uljane repice dobar je izvor sirovih bjelančevina povoljnog aminokiselinskog sastava, te kalcija i fosfora. Budući da su višegodišnjim selekcijskim radom stvoreni hibridi uljane repice sa smanjenim sadržajem antinutritivnih tvari, provode se istraživanja glede udjela pogače uljane repice u hranidbi različitih vrsta peradi. Cilj ovog istraživanja bio je utvrditi utjecaj 5 i 10% pogače uljane repice (kultivara Bristol) u krmnim smjesama na proizvodna svojstva 108 hibridnih gusaka podijeljenih u 12 skupina, do dobi od 8 tjedana. Završne tjelesne mase iznosile su 4224.32, 4280.00 i 4290.9 g, te nije utvrđena signifikantna razlika (p>0.05) gledano po tretmanima. Konverzija krmne smjese na kraju istraživanja iznosila je 2.99, 3.03 i 3.18 kg/kg, dok je mortalitet gusaka bio 0.00, 2.78 i 8.33%. Na temelju povećane konverzije krmne smjese i mortaliteta kod skupina hranjenih krmnim smjesama koje su sadržavale 10% pogače uljane repice ona se može primijeniti u krmnim smjesama u udjelu do 5%.Rapeseed oil cake is a good source of protein with a favorable amino acid content as well as calcium and phosphorus content. Over the years of selection work a new hybrid of rapeseed with reduced antinutritive substances was created. Feeding trials on various poultry species with different share of rapeseed oil cake are carried on. The aim of this experiment was to determine the influence of 5% and 10% rapeseed oil cake (Bristol) in rations on production properties of 108 hybrid geese divided in to 12 groups to 8 weeks of age. After the trial the body weight was 4224.32, 4280.00 and 4290.91 g. respectively and there was no significant (p>0,05) difference between treatments. Feed conversion at the end of the trial was 2.99, 3.03 and 3.18 kg/kg while mortality was 0.00, 2.78 and 8.50% respectively. Due to higher feed conversion and higher mortality in trial groups fed 10% rapeseed oil cake in ration, its 5% share in ration can be recommended for feeding hybrid geese
