Abstract

Hranidba životinji omogućuje opskrbu potrebnim hranjivim tvarima koje dobiva iz krmiva preko niza biokemijskih i fizioloških procesa koji se odvijaju u organizmu životinje. Zato je nužno istražiti različite aspekte hranidbe domaćih životinja s ciljem maksimalnog iskorištenja potencijala ponuđene hrane. U tu se svrhu provode pokusi probavljivosti na živim životinjama (in vivo) koji prate razliku između količine hranjivih tvari unesenih obrokom i količine hranjivih tvari izlučenih izmetom. Primjena aditiva kod pripreme silaže ima mnoge pozitivne učinke poput smanjenja gubitka hranjiva, povećanje hranidbene vrijednosti silaže, poboljšanje kvalitete fermentacije u silosu, može poboljšati animalnu proizvodnju i povećati sadržaj suhe tvari (ST). Cilj ovog rada bio je utvrditi utjecaj primjene aditiva na konzumaciju suhe tvari i in vivo probavljivost suhe tvari sjenaže u hranidbi kastriranih ovnova. Rezultati rada pokazali su da je dodatak aditiva utjecao na povećanje (P < 0,001) ad libitum konzumacije suhe tvari i in vivo probavljivosti suhe tvari silaže u odnosu na silažu koja nije bila tretirana aditivima.

Abstract (english)

Feeding the animal enables the supply of necessary nutrients derived from the feed through a series of biochemical and physiological processes occurring in the animal organism. Therefore, it is necessary to explore different aspects of nutrition in domestic animals with the aim of maximal utilization of food offered. For this purpose, the digestibility experiments with living animals (in vivo) are carried out, which follow the difference between the quantity of nutrients fed and excretes through feces. The application of additives at ensiling might have many positive effects on fermented forage such as reducing nutrient loss, increasing nutritional value of silage, improving the quality of fermentation in a silo and animal production, increaseinge the dry matter (DM) concentration. The aim of this study was to determine the influence of additives supplementation on DM ad libitum intake and in vivo digestibility in the ration of wether sheep. The results of the work showed that the additive supplementation to increased (P < 0.001) ad libitum DM intake and in vivo digestibility in comparison with the control feeding treatment.
