Abstract

Cilj istraživanja bio je utvrditi utjecaj modificiranih ugljikohidrata stijenke kvasca u krmnim smjesama na proizvodne rezultate pilića u tovu. Korištena su 300 muških jednodnevnih pilića hibrida Ross 308 koji su slučajnim odabirom smješteni u 2 skupine sa 6 ponavljanja. Tokom istraživanja pilići iz kontrolne skupine bili su hranjeni starterom s 24,0 % SB (14 dana), finišerom I s 21,0 % SB (14 dana) i finišerom II s 20,0 % SB (10 dana). Pilići u pokusnoj skupini su hranjeni istom smjesom kao kontrolna skupina s dodatkom modificiranih ugljikohidrata. U starter je dodano 800 g, finišer I 400 g, a u finišer II 200 g po toni krmne smjese. Prilikom promjene smjesa, pilići su vagani. Prosječne tjelesne mase pilića na kraju istraživanja su bile 2808,86 g u kontrolnoj i 2880,42 g u pokusnoj skupini. Konverzija krmnih smjesa je iznosila 1,58 i 1,56 kg/kg tjelesne mase u kontrolnoj i pokusnoj skupini. Pošto su tjelesne mase u pokusnoj skupini veće za 2,62 %, ali ne statistički značajne, a konverzija niža za 1,27 % (p>0,05), preporučuje se korištenje modificiranih ugljikohidrata stijenke kvasca u krmnim smjesama za hranidbu pilića.

Abstract (english)

The aim of this study was to determine the effect of yeast wall modified carbohydrate to diets on the performance of broiler chickens. In the study were used 300 male day-old chicks hybrid Ross 308 which were randomly placed in two groups of 6 repetitions. During the research, the chickens in the control group were fed with starter with 24.0 % CP (14 days), finisher Iwith 21.0 % CP (14 days) and finisher II with 20.0 % CP (10 days). The chickens in the test group were fed the same feed mixture as the control with the addition of modified carbohydrates. In the Starter was added 800 g, in Finisher I 400 g and in Finisher II 200 g per ton of feed. The chickens were weighed after each feed mixture were changed. Average body weights at the end of the study were 2808.86 g in the control and 2880.42 g in the experimental group. Conversion of compound feed amounted to 1.58 and 1.56 kg/kg body weight in the control and experimental group. Since the body weight in the experimental group increased by 2.62 %, but not statisticly significant and conversion was lower by 1,27 % (p>0.05), it is recommended to use of yeast wall modified carbohydrate in feed mixtures for broiler chickens.
