Sažetak
Cilj ovog rada bio je da se istraži uticaj smese prehrambenog graška: lanenog semena (3:1) na proizvodne performanse i određene biohemijske parametre seruma kod odlučene prasadi. Takođe su ispitane fekalne bakteriološke i fungalne kulture, kao i pojava dijareje. Ukupno dvadeset odlučenih prasadi starosti od 28 ± 3 dana bilo je nasumično podeljeno u dve grupe: kontrolna grupa (C dijeta) sa klasičnom ishranom (kukuruz i sojina sačma) i ogledna drupa (GL dijeta 3:1). Lipidni i proteinski sastav utvrđen je pomoću uređaja Analyser BS - 130. Koncentracija kortizola seruma određena je pomoću uređaja Immulite 2000 (Siemens). Koncentracija lipaze seruma je određena spektorofotometrijskom metodom. Ukupan broj mikroorganizama u uzorku fecesa određen je metodom brojanja kolonija na odabranim podlogama za svaki mikroorganizam. Dodavanje smese grašak: laneno seme nije značajno uticalo na proizvodne performance prasadi (p>0,05). Markeri seruma: holesterol, trigliceridi, ukupni proteini i njihova frakcija se takođe nisu značajno razlikovali između tretmana. Osim proteina, čiji je sadržaj bio neznatno ispod preporučenih granica, ostali markeri bili su u preporučenim fiziološkim granicama. Sadržaj masti bio je sličan kod obe grupe prasadi. Nivo lipaze u serumu kod ispitivane prasadi bio je nešto manji u oglednoj grupi u odnosu na kontrolnu, ali razlika nije bila statistički značajna (<9,06% u GL dijeti u poređenju sa C dijetom). Niži nivo lipaze seruma u oglednoj grupi (GL dijeta) ogledao se u višem nivou triglicerida (> 1,10 puta) i holesterola (> 1,06 puta). Nivo kortizola smanjen je za 94% u oglednoj grupi. Izvor biljnih proteina nije imao značajan uticaj na bakterije iz fecesa. Nakon dve nedelje od odbijanja, broj bakterija je postepeno postajao viši u oglednoj grupi (GL dijeta) u poređenju sa kontrolnom (C dijeta), što je pokazala i veća učestalost dijareje. Može se zaključiti da grašak i laneno seme predstavljaju dragocene izvore biljnih proteina za odlučenu prasad, a njihova kombinacija pruža mogućnost optimizacije ishrane.
Abstract
The objective of this work was to investigate the influence of dietary peas: linseed mixture (3:1) on the performance and certain serum biochemical parameters of weaned piglets. The faecal bacteriological and fungal composition and diarrhoea incidence was done as well. A total of 20 weaned piglets, 28 ± 3 days of age, were assigned randomly to 2 groups: control diet (C diet) with a classical diet (corn and soybean meal) and peas: linseed diet (PL diet, 3:1). The lipid and protein profile were determined by Analyser BS - 130. The cortisol serum concentration was determined with an Immulite 2000 (Siemens). The serum lipase concentration was determined by the spectropho - tometer method. The number of microorganisms from the faeces samples was determined by counting the colonies obtained on selected media for each particular microorganism. The dietary additismogisaac@gmail.comon of peas: linseed mixture did not influence the performance (P>0.05). The serum markers: cholesterol, triglycerides, total protein and their fraction did not differ significantly between treatments. Except the protein, which was slightly under the recommended limit, the other markers were within the physiological limits. The dietary fat content was similar. Serum lipase level in weaned piglets decreased insignific antly by dietary incorporation of pV10.5937/FFR1702173Heas: linseed (<9.06% in PL diet compared to C diet). The lower level of serum lipase in PL diet was reflected in a higher level of triglyceride (>1.10 times) and cholesterol (>1.06 times). The cortisol level was reduced by 94% by peas: linseed addition. The vegetable protein source did not have a significant influence on the bacteria of the faeces. After 2 weeks from weaning, the bacteria count was slowly higher in PL diet compared to C diet, as shown by a higher incidence of diarrhoea. We can conclude that peas and linseed are valuable vegetable sources for weaning piglets, their combination delivering an opportunity to have an optimal diet.
