U radu je istražen sastav masnih kiselina u mesu biserke (Numida meleagris), običnog fazana (Phasianus colchicus), japanske prepelice (Coturnix coturnix japonica), jarebice čukare (Alectoris chucar), trčke skvržulje (Perdix perdix) i divljeg purana (Meleagris gallopavo). Istražena je razlika između sastava masnih kiselina u prsnom mišiću i mišićju buta svake vrste posebno, a dobivene razlike uspoređene su i između svih vrsta. U mastima istraživanih vrsta pernate divljači praćen je sadržaj zasićenih i nazasićenih masnih kiselina te sadržaj pojedinačnih masnih kiselina iz skupine MUFA i PUFA. S aspekta ishrane ljudi interes je bio usmjeren posebice na sadržaj masnih kiselina iz skupine ω-9, ω-6 i ω-3 te na međusobni odnos ω-3/ω-6 masnih kiselina. Na temelju dobivenih rezultata istraživanja procijenjena je nutritivna vrijednost masti u mesu navedene pernate divljači., The study evaluates fatty acid composition of fat in meat of six species of feathered game – helmeted guineafowl (Numida meleagris), the common pheasant (Phasianus colchicus), Japanese quail (Coturnix coturnix japonica), chukar partridge (Alectoris chucar), the grey partridge (Perdix perdix) and wild turkey (Meleagris gallopavo). Attention was paid to the differences between breast and thigh muscles as well as to the differences between the particular species of feathered game. We monitored the saturated and unsaturated fatty acids and the individual fatty acids content from MUFA and PUFA families. With regard to human nutrition, we paid attention to the ω-9, ω-6 and ω-3 acids content and especially to the ratio of ω-3 to ω-6 fatty acids. Based on our results, we evaluated the nutritional value of fat in meat of these species of feathered game in relation to the human nutrition.

Partridges ( Perdix perdix ), chukars ( Alectoris chukar ), wild guineafowl ( Numida meleagris ), wild turkeys ( Meleagris gallopavo ) and chickens ( Gallus domesticus ) were inoculated per os with 103 or 105 Toxoplasma gondii oocysts (K7 strain). Two of five partridges fed 103 oocysts and six of eight partridges fed 105 oocysts died between day 6 and 16 post-inoculation (p.i.); no clinical symptoms were observed in surviving birds. Antibodies to T. gondii were detected in the birds by the indirect fluorescence antibody test (IFAT) first on day 7 p.i. On days 14, 21 and 28 p.i. (end of the experiment), antibodies were found in all partridges, chukars, guineafowl and turkeys. In chickens, IFAT antibodies were first detected on day 14 p.i., and all chickens were serologically positive on days 21 and 28 p.i. Bioassay in mice revealed T. gondii in the brain, liver, spleen, heart and leg muscles of all partridges and chukars. Enteritis was the most striking lesion in partridges that died. Results indicated that partridges are highly susceptible to toxoplasmosis, while chukars, wild guineafowl and turkeys seem to be less susceptible. Chickens are highly resistant to T. gondii infections.

Cilj ovog rada bila je usporedba klaoničkog randmana i randmana značajnih organa i tkiva između šest vrsta pernate divljači: divljeg purana (Meleagris gallopavo), biserke (Numida meleagris), čukare (Alectoris chucar), japanske prepelice (Coturnix coturnix japonica), običnog fazana (Phasianus colchicus) i trčke skvržulje (Perdix perdix). U svrhu istraživanja u siječnju 2007. godine od svake je vrste zaklano i analizirano10 ptica (5 mužjaka i 5 ženki). Navedena pernata divljač uzgojena je pod istim uvjetima u uzgajalištu peradi u Jinačovice (Češka republika), u uzgojnom centru u sklopu Veterinarskog i farmaceutskog fakulteta Sveučilišta u Brnu. Pernata divljač uzgajana je u volijerama s istovjetnim sustavom hranjenja i pojenja, a za istraživanje odabrana je metodom slučajnog izbora. Odmah nakon odabira pernata divljač je izvagana, zaklana i klaonički obrađene na klasičan način, slično kao i pilići u tovu. Posebna pozornost posvećena je masi trupa, vrata, srca, jetre, želuca, abdominalne masti, prsnih mišića, bataka (s kožom i bez kože), zabataka, te muskulaturi zabataka i bataka. Na temelju dobivenih podataka, s obzirom na živu masu pernate divljači izračunat je klaonički randman i randman pojedinačnih organa i tkiva. Iz dobivenih rezultata istraživanja proizlazi da su razlike u klaoničkom randmanu i randmanu istraživanih organa i tkiva meču pojedinim vrstama pernate divljači značajne (P< 0,05). Najveći klaonički randman utvrđen je kod prepelica (71,14 %), nešto niži kod biserki (70,61 %), običnog fazana (69,74 %), trčke skvržulje (69,09 %) i čukare (68,92 %), a najniži kod divljeg purana (67,99 %). Značajne razlike (P, The aim of this study was to compare the slaughter dressing and the dressing of characteristic organs and tissues of six breeds of wildfowl: wild turkey (Meleagris gallopavo), guinea-fowl (Numida meleagris), chukor (Alectoris chucar), Japanese quail (Coturnix coturnix japonica), common pheasant (Phasianus colchicus) and grey partridge (Perdix perdix). For the purpose of the study, in January 2007, 10 birds of each species were slaughtered (5 males and 5 females)and analysed. The birds were bred in equal conditions in the breeding centre of the Veterinary and Pharmaceutical Faculty, University in Brno. The birds were bred in roosts applying equal system of feeding and watering systems and were randomly selected for the study. Immediately following the selection the birds were weighed, slaughtered and processed in the conventional method, similar to that in chickens intended for slaughter. A special attention was paid to the weight of the trunk, neck, heart, liver, stomach, abdominal fat, breast muscles, drumsticks (with and without skin), upper legs and the muscles of the upper legs and drumsticks. On the ground of the data obtained with respect to the live weights of the birds, slaughter dressing and the dressing of individual organs and tissue were calculated. The results obtained show that differences in slaughter dressing and the dressing of the investigated organs and tissue between some breeds are significant (P
