THE POSSIBILITY OF CONDENSED MOLASSES "VINASSA" UTILIZATION FOR THE FEEDING OF THE LIGHT HYBRID LAYERS

U pokusu provedenom na 1037 nesilica, koje su komercijalni hibrid Nick Chick (namijenjenih proizvodnji konzumnih jaja) istraživali smo mogućnost zamjene dijela kukuruzne prekrupe i pšeničnih posija ugušćenom melasnom đibrom, uključivanjem u pokusne smjese na razinama 1, 3 i 60%. Pokus je trajao 168 dana i bio je podijeljen u 6 razdoblja po 28 dana, na završetku kojih smo vršili obračun nesivosti, potroška i iskorištenja hrane, težine jaja, broja manje vrijednih i bezvrijednih jaja, također su izvršena mjerenja čvrstoće ljuske te određene kategorije jaja i boja žumanjka jaja. Sve tri pokusne skupine hranjene sa 1, 3 i 60 % ugušćene melasne đibre, ostvarila su veću nesivost (P>0,05) od kontrolne skupine nesilica. Najveću nesivost ostvarila je skupina s 3% ugušćene melasne đibre u obroku. Prosječni dnevni utrošak bio je jednak u svim skupinama, a najveći utrošak hrane za proizvodnju jednog jajeta imala je kontrolna skupina. Prosječna težina jaj bila je niža u pokusnim skupinama (>0,05). Pokusne skupine imale su čvršću ljusku a broj snesenih jaja značajno se povećao. U usporedbi prema kontroli boja žumanjka i kemijski sastav bjelanjka i žumanjka u pokusnim skupinama nisu pokazali nikakva odstupanja. Rezultati provedenog pokusa upućuju na mogućnost djelomične zamjene kukuruzne prekrupe i pšeničnih posija ugušćenom melasnom đibrom u smjesama za lako hibridne nesilice

Effect of feeding olive by-products on certain blood parameters and serum enzyme activities of fattening rabbits

The effect of feeding different levels (10 and 20%) of dehydrated olive cake pulp on certain blood parameters and on the catalytic activity of serum enzymes was studied in fattening rabbits. A total of 60 rabbits were divided into a control group (C) and two experimental groups (E1, E2), each comprising 10 males and 10 females. Rabbits of Group C received no dehydrated olive cake pulp in their diet, while rabbits of Group E1and Group E2were fed 10% and 20% dehydrated olive cake pulp, respectively. After Day 56 of the experiment, blood samples were obtained by cardiac puncture and certain blood parameters as well as the catalytic activity of serum enzymes were determined. Following the experimental feeding period no significant differences were found between Group C and Groups E1and E2in red blood cell (RBC) and white blood cell (WBC) count, haemoglobin concentration and haematocrit value. Similarly, after 56 days of experimental fattening no significant differences were found between the control group and the experimental groups in the catalytic activity of the serum enzymes alkaline phosphatase (AP), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), and lactate dehydrogenase (LDH). However, Group E2 rabbits manifested a significantly higher alanine aminotransferase (ALT) activity in the serum than did rabbits of Group E1. The results indicate that the inclusion of dehydrated olive cake pulp in the diet at the rate of 10% or 20% caused no changes in the investigated blood parameters and serum enzyme activities of fattening rabbits
