Abstract :

There are many researches about different prebiotics which can increase live weight and at the same time can reduce methane production in livestock (Fao, 2010; Mirzaei-Aghsaghali, 2015). There are no information about prebiotic inulin, so the aim of this research was to determine the impact of different dosages of inulin concentrate (50%) on increase of calvesâ?? body weight and methane emission. Four week clinically healthy different Holstein Friesian crossbreed calves (n=24) which were kept in groups of 8 calves in partly closed space with passive ventilation system divided into three groups: control group (CoG; n=8) and 2 groups fed with additional flour supplement (Pre12 (n=8); Pre24 (n=8). The length of research was 57 days, during this time on research start day, 29th and 57th day we determined each calf â??s weight and methane emission PICARROG-2508 (Fleck, 2013). Conclusion: 1. We found out that inulin supplement showed good results of live weight gain at the end of the research comparing Pre24 and CoG (P=95%). In Pre24 it was 128?±18.8kg and in CoG 116?±7.1kg, also there was a significant (P=95%) difference between Pre12 and Pre24â?? respectively 114?±12.4kg and 128?±18.8kg. 2. The biggest methane emission on 1 kg body weight at the end of the research was noticed in CoG â?? 5.72?±0.08 mg/m3, comparing to Pre12â?? 4.10?±0.06 mg/m3 and Pre24 â?? 4.17?±0.05 mg/m3. 3. The highest amount of methane in surrounding space where calves were kept was noticed in Pre24 â?? 15.4?±0.77 mg/m3, comparing to Pre12 â?? 13.8?±0.7769 mg/m3 and CoG â?? 10.2?±0.51 mg/m3.
