Eco-fish meal as an alternative to fish meal in diets for lambs

Abstract

The effect of Eco-fish meal, as an alternative to fish meal, on the production performance of the lambs of the Mis population in the intensive fattening, was investigated. The experiment was carried out on 40 lambs, the average age of 30 days, divided in 2 groups. In addition to mother's milk, the lambs were given a concentrated mixture and a lucerne hay, at will. Isoprotein forage mixtures (16% of total proteins) differed in terms of the protein component. The protein source for treatment I had fish meal, while the animals on treatment II consumed EcoFish, a herbal substitute for fish meal, which consisted of domestic foods of known origin such as genetically unmodified and thermally treated meal of decorticated soybean grains, soybean protein isolates, gluten, livestock yeast with the addition of minerals, amino acids, vitamins, enzymes and other additives. Statistical processing of the obtained data was done using the SPSS STATISTICA, Version 20. On treatments I and II, the average daily lamb gain was 320 and 283 g, respectively, without statistical significance. The consumption of dry matter and proteins in analogue treatments was 0.819 and 0.823 kg, and 152.62 and 157.04 g, respectively. The dry matter consumption per kilogram of gain (kg/kg of gain) was 2.56 and 2.91; of energy (MJ NEM/kg): 17.65 and 20.25; of total proteins: 476.9 and 554.9 g, respectively. The protein efficiency ratio - PER (g of gain/g of consumed protein) in analogue treatments was: 2.09 and 1.80. There were no statistically significant differences between examined treatments (P> 0.05). Considering that the source of protein did not significantly affect the intensity of growth and the use of food by lambs of Mis population in intensive fattening (P>0.05), fish meal can be replaced by Eco-fish meal - plant protein, since according to Commission Decision 9/2001 on BCE protection (OJEC, 2001), there is a distance to the use of fish meal, as a source of protein.

Ispitivan je uticaj eko fiš meal kao alternative ribljem brašnu, na proizvodne performanse jagnjadi Mis populacije, u intenzivnom tovu. Eksperiment je izveden na 40 jagnjadi, prosečnog uzrasta 30 dana, raspoređenih u 2 grupe. Pored majčinog mleka, jagnjad su dobijala koncentrovanu smešu i lucerkino seno po volji. Izoproteinske krmne smeše (16% ukupnih proteina) su se razlikovale u pogledu proteinske komponente.Izvor proteina na tretmanu I je bilo riblje brašno, dok su grla na tretmanu II konzumirala Eko fiš meal-biljnu zamenu za riblje brašno, koja se se sastojala od domaćih hraniva poznatog porekla kao što su genetski nemodifikovano i termički obrađeno brašno oljuštenog zrna soje, izolat proteina soje, glutena, stočnog kvasca uz dodatak minerala, aminokiselina, vitamina, enzima i drugih dodataka. Statistička obrada dobijenih podataka je izvršena korišćenjem SPSS STATISTICA, Version 20. Na tretmanima I i II, prosečan dnevni prirast jagnjadi je iznosio: 320 i 283 g, bez statističke značajnosti. Konzumiranje suve materije i proteina na analognim tretmanima, je iznosilo: 0.819 : 0.823 kg, odnosno 152,62 : 157,04g. Utrošak suve materije po kilogramu prirasta je(kg/kg prirasta) je iznosio: 2,56 : 2,91; energije (MJ NEM/kg): 17,65 : 20,25; ukupnih proteina: 476,9 : 554,9 g. Efikasnost iskorišćavanja proteina - PER (g prirasta/g konzumiranog proteina) na analognim tretmanima je iznosila: 2,09 i 1,80. Nisu ustanovljene statistički značajne razlike između ispitivanih tretmana (P>0,05). Obzirom da izvor proteina nije značajno uticao na intenzitet rasta i iskorišćavanje hrane kod jagnjadi Mis populacije u intenzivnom tovu (P>0,05), riblje brašno se može zameniti Eko fiš-meal- biljnim izvorom proteina, budući da prema odluci Komisije 9/2001 o zaštiti BCE (OJEC, 2001),postoji distanca prema korišćenju ribljeg brašna, kao izvoru proteina.
