Efficiency of zeolite basis preparation in fattening lambs diet

Abstract

The paper presents the results of a research on the impact of products based on natural zeolite on the production results of fattening lambs. The experiment involved two groups of lambs (the control - C and experimental - E groups), each consisting of 15 heads, for a period of 90 days. The meal was made from sheep milk, feed mixtures for fattening lambs and meadow hay. The test group lambs, unlike the ones from the control group, were given mixtures based on natural zeolite. Min-a-Zel S mixture (in the form of 25% composite) was fed to lambs from birth till their 14th day of life, directly into the mouth, once a day (before the morning feed), in the amount of 10 ml. Min-a-Zel Plus was given to them from their 15th day of life, together with the feed mixture (0.5%). Feeding was at will. The average weight of lambs at the end of the experiment, in accordance with the sequence of treatments (C:E) was 24.40:26.94 kg (P (lt) 0.01). Daily weight gain of lambs, during the experiment, was 229:256 g and in the experimental group it was by 27g or 11.79% higher (P (lt) 0.01). The test group lambs had a better utilization of dry matter, protein and energy, which justifies the use of products based on natural zeolite in fattening lambs.

U radu su prikazani rezultati istraživanja o uticaju preparata na bazi prirodnog zeolita na proizvodne rezultate jagnjadi u tovu. Ogled je izveden na dve grupe jagnjadi (kontrolna - K i ogledna - O), po 20 jagnjadi u trajanju od 90 dana. Obrok se sastojao od ovčjeg mleka, krmne smeše za tov jagnjadi i livadskog sena. Iskorišćavanje preparata na bazi zeolita (Min-a-Zel S i Min-a-Zel Plus) pozitivno je uticalo na prirast, iskorišćavanje i efikasnost iskorišćavanja suve materije, proteina i energije. Prosečan dnevni prirast bio je veći kod jagnjadi ogledne grupe za 27 g ili 11,79 posto. Utrošak suve materije za kilogram prirasta u istoj gupi, bio je manji za 12,21 posto a proteina i energije za 10,58 posto. Manja učestalost javljanja proliva bila je kod jagnjadi ogledne gupe.
