Abstract

Investigations were carried out in order to determine whether the addition of bioactive substances "Bioril" on different percentages in concentrate (0.3% and 0.6%), has an impact on weight gain and feed conversion in lambs. For the experiment were used lambs of Mis sheep breed, which at the beginning of the experiment were 50 days of age. The experiment lasted 42 days, so it is over when all lambs had 92 days of age. The experiment included 60 lambs (30 male and 30 female) were divided into three groups-20 lambs per group (control group I and II and III experimental groups ).The results shows that the greatest gains made lambs of group III. The difference between body weight of group I and II was 1.62 kg and was statistically significant (P<0.01). The difference between body weight of I and III group was 1.87 kg and was also statistically significant (P<0.01). The difference between the body weight of II and III groups was 0.25 kg and was not statistically significant (P>0.05). We find that lambs of all groups consumed per kg of gain more concentrated than hay. The difference in feed conversion between groups is not significant (P>0.05), but lambs of groups III and II consumed per unit of gain approximately 5g/kg and 10g/kg less concentrate than lambs of group I. Most hay consumed by lambs of group I. The difference in hay consumption between groups I and II is 20 g/kg. Lambs in group III consumed 30 g/kg which was less hay than group I and less 10 g/kg than lambs of group II. The most energy per kg of gain was consumed by lambs of group III, whereas lambs in II group consumed the least energy.

In majority countries of Europe, lamb meat is the most important product of the sheep and growth of lambs has special interest for the farmers

Summary

Introduction

In majority countries of Europe, lamb meat is the most important product of the sheep and growth of lambs has special interest for the farmers. Because of the small volume of digestive organs of lambs on one side and greater intensity of growth on the other, some unconventional feeds are used, such as fats of animal origin (Diaz et al, 2002; Samy,2006; Ružić-Muslić et al, 2007). Bioactive Supplements "Bioril" is concentrated salt sodium fatty acids, which comes from sheep wool fat sweat. Bioril is highly effective and environmentally clean product promotes active development of the microflora in the rumen, increased enzymatic processes, increase the total number of VFA and total lipids, while the hydrogenation processes are enhanced, there is a rapid growth of body weight and wool growth in sheep (Ermolovna, 1998, Novopashina, 1999)
