This research aimed to determine the meat production indicators and carcass traits of Posavska crested hen, which is the Croatian indigenous chicken breed. The research was carried out on five ...strains of the Posavska crested hen breed: yellow vetch, vetch, red colourful, light gray, and golden brown. Feeding was ad libitum for the whole time, adapted to the age of the chickens from a nutritional point of view. Separation by sex was carried out at the age of four weeks, while slaughter of roosters and determination of carcass traits was done at the age of 18 weeks. The highest average body weight was achieved by roosters of light gray and yellow vetch strain (3542.63 and 3430.38 g, respectively) and light gray pullets (2562 g) at the age of 18 weeks. The lowest feed conversion ratio was achieved by the light gray strain (2.39) at four weeks of age, and by the the roosters of the light gray strain (4.07) and pullets of the light gray and golden brown strain (4.08) at 18 weeks of age. The average dressing percentage was 71.54%, while the highest average dressing percentage was established in the red colourful strain (72.48%). Regarding the proportion of individual parts of the carcass, a significant (P < 0.05) influence of the strain can be seen in the proportion of drumsticks in the carcass, the proportion of which was the highest in the yellow vetch strain (18.69%). A significant influence of the strain was also found regarding L* (P < 0.01) and a* (P < 0.05) skin color indicators. Considering the established differences between the strains, it is necessary to carry out further selection and work on the uniformity of the breed.

Križevačka kukmasta kokoš nastala je u osamdesetim godinama 20. stoljeća selekcijskim radom na domaćim kokošima uzgajanim u Kalničkom prigorju, koje je karakterizirala osrednja kukmica te srednje ...teško tijelo. Te su kokoši planski križane s pijetlovima pasmine Orpington. Do današnjeg vremena nisu provedena znanstvena istraživanja kako bi se dobile spoznaje o njihovim fenotipskim i proizvodnim karakteristikama pa je stoga cilj ovog istraživanja bio utvrditi vrijednosti tjelesnih mjera kokoši i pijetlova te odrediti izgled i kakvoću jaja kako bi se moglo započeti s izradom pasminskog standarda potrebnog za njezino priznavanje kao autohtone pasmine kokoši. U istraživanje su bile uključene kokoši i pijetlovi s četiri obiteljska gospodarstva na području grada Križevaca. Utvrđena je boja perja, nogu i podušnjaka kod životinja u dobi od šest mjeseci i godinu dana te su iste izvagane, a provedeno je i mjerenje vrijednosti za još deset tjelesnih mjera. Prikupljena su i kokošja jaja kako bi se utvrdile vrijednosti mase jaja, čvrstoće ljuske, udjela žutanjka, bjelanjka i ljuske te utvrdila boja žutanjka. Križevačka kukmasta kokoš je skladnog tijela kvadratnog oblika i bujnog perja žute boje obrubljenog tamnom gotovo crnom bojom. Glava je srednje veličine, na njoj se nalazi kukmica narančasto-žute boje kod pijetlova, a crno-smeđe kod kokica. Tjelesne mase pijetlova u dobi od 6 i 12 mjeseci u prosjeku su iznosile 2,33 i 2,95 kg, a kod kokoši u istoj dobi 2,06 i 2,71 kg.
Distribucija polimorfizma dužine restrikcijskog fragmenta (RFLP) preko gena za ovalbumin zagorskog purana i hibridnih pilića bila je mapirana u genomu DNA izoliranom iz krvi 30 životinja koje su ...predstavljale četiri soja. Rabeći iste početnice lančana reakcija polimeraze (PCR) upotrijebljena je za umnažanje ovalbumin gena genomske DNA purana i pilića. Uz veličinu umnoženog gena za ovalbumin, redoslijed restrikcijskih fragmenata određen je usporedbom mapa EcoRI, HaeIII, PvuII i AvaI položaja kod zagorskog purana i pilića. Duljine PCR proizvoda dobivenih iz 40 genomskih DNA purana bile su 2,47 MB i bile su bez značajne razlike. Dva polimorfna restrikcijska mjesta PCR proizvoda kao što su AvaI mjesto na poziciji 2150 bp i PvuII mjesto na 1718 bp omogućavaju genotipizaciju zagorskih purana i pilića. Naši rezultati ukazuju na to da je dio gena za ovalbumin identičan u sva četiri soja zagorskog purana na području Hrvatskog zagorja. Pri usporedbi dijela gena za ovalbumin između pilića i zagorskog purana uočena je velika polimorfna raznolikost.
Slobodan način držanja kokoši nesilica jedan je od propisanih alternativnih načina proizvodnje kokošjih jaja u Europi, a proizvodnja konzumnih jaja na obiteljskim gospodarstvima u Hrvatskoj uglavnom ...se odvija na taj način. Cilj istraživanja bio je utvrditi proizvodnost hrvatske autohtone pasmine kokoši hrvatice u uvjetima slobodnog
načina držanja. Kokoši u dobi od 20 tjedana useljene su na 11 obiteljskih gospodarstava, pri čemu su na svakom bila dva jata po 10 kokoši. Praćenje proizvodnih rezultata trajalo je 32 tjedna Sve kokoši su hranjene po volji kompletnom krmnom smjesom koja je sadržavala 15% sirovih bjelančevina i 11,28 MJ/ME, a na raspolaganju su imale i zatravnjeni ispust po 10m2 po kokoši. Praćen je broj i masa jaja te konzumacija krmne smjese. Za utvrđivanje čvrstoće ljuske, boje žutanjaka i vrijednosti Haugh unit iz svakog je jata u 10 tjednu istraživanja prikupljeno 10 jaja. Cost benefit analizom izračunati su ekonomski pokazatelji proizvodnje. Prosječan broj jaja po nesilici tijekom istraživanja iznosio je 130,98 jaja, konverzija krmne smjese
3.46 /kg jajčane mase, a prosječna masa jaja iznosila je 51,4 grama. Čvrstoća ljuske bila je 3.10 kp/cm2, boja žutanjka 11 po skali La Roche, a vrijednost Haughovih jedinica 66.02. Ukupni prihodi koji su uključivali iznose dobivene prodajom jaja i državna poticajna sredstva bili su 57.742,50 kn, dok su ukupni varijabilni troškovi bili 21.666,60 kn. Pokriće varijabilnih troškova za svih 11 obiteljskih gospodarstava
iznosilo je 36.075,90 kn odnosno 3279,63 kn za jedno gospodarstvo. Prema navedenom zaključujemo da se kokoš hrvatica može u potpunosti preporučiti za proizvodnju jaja slobodnim načinom držanja na malim obiteljskim gospodarstvima u Hrvatskoj.
Amiloidoza je generički pojam koji se odnosi na postojanje lokaliziranog ili difuznog nakupljanja fibrilarnih proteina u izvanstaničnom prostoru različitih organa. Sekundarna (AA) amiloidoza je ...rijetka, ali ozbiljna komplikacija koja nastaje u bolesnika s kroničnim upalnim procesima i malignomima. Prikazujemo 39-godišnjeg bolesnika kojem je prije 18 godina postavljena dijagnoza Crohnove bolesti. Hospitaliziran je zbog pogoršanja kliničkog stanja u obliku tjestastih edema nogu te reevaluacije osnovne bolesti. Kolonoskopijom i rentgenskom pasažom crijeva potvrđena je aktivnost osnovne bolesti. U laboratorijskim nalazima bilježio se porast upalnih reaktanata, normocitna anemija, hipokalcemija, hipoalbuminemija te hipoproteinemija. Klirens kreatinina iznosio je 66 mL/min, a proteinurija >24 grama/L. Učinjena je biopsija bubrega a patohistološkom obradom verificirana je sekundarna amiloidoza. S obzirom na već postojeću aktivnu upalnu bolest crijeva predloženo je aktivno liječenje indukcijom kortikosteroidima, kako bi se postiglo remisiju, te azatioprinom uz obradu za eventualnu terapiju infliksimabom, na što bolesnik u tom trenutku nije pristao. Prognoza bolesnika sa sekundarnom AA amiloidozom i bubrežnom insuficijencijom je loša te 50% bolesnika umire unutar 5 godina od postavljanja dijagnoze. Do sada ne postoji uspješno specifično liječenje sekundarne amiloidoze, već je terapijski pristup usmjeren prije svega na liječenje primarne bolesti.
Amyloidosis is a clinical entity that results from deposition of an extracellular protein material that causes disruption in normal architecture and impairs function of multiple organs and tissues. ...Secondary amyloidosis (AA) is a rare but serious complication that occurs in the context of cancer, chronic inflammation and chronic infectious diseases, including inflammatory bowel disease, mainly long-standing Crohn's disease. Renal failure is the most common clinical presentation of AA, ranging from nephrotic syndrome and impaired renal function to renal failure, with a potential for high morbidity. The incidence of the association of secondary amyloidosis in patients with Crohn's disease has been reported to be 0.5%-8%. We present a case of a 39-year-old male patient diagnosed with Crohn's disease at age 21 and submitted to right hemicolectomy because of ileus 17 years before. Thereafter, he was treated with corticosteroids for 15 years and with azathioprine for a short period; in the last three years he was on therapy with mesalazine alone. He was hospitalized due to worsening clinical condition and re-evaluation of the underlying disease. Physical examination revealed marked peripheral edema in both lower extremities. Endoscopic and radiographic examinations confirmed the underlying disease activity. Laboratory tests showed an increase of inflammatory reactants, anemia, hypocalcemia, and severe hypoalbuminemia and hypoproteinemia. He had proteinuria over 24 g/L and creatinine clearance of 66 mL/min, falling within second grade of chronic kidney disease. Renal biopsy was performed for evaluation of renal insufficiency with nephrotic range proteinuria. Congo red staining showed the presence of characteristic amyloid deposition; deposits immunoreacted with the antibody against amyloid A protein, confirming the diagnosis of secondary amyloidosis. The patient was suggested active induction treatment with corticosteroids and azathioprine to achieve remission of Crohn's disease, thereafter treatment with infliximab, but he did not consent with this therapy at that time. Studies with infliximab have demonstrated a decrease in SAA circulating levels and proteinuria, as well as stabilization of renal function. Amyloidosis is frequently described as a major cause of death in patients with Crohn's disease, with long-term mortality between 40% and 60%. Various therapeutic attempts such as azathioprine, colchicine, dimethyl sulfoxide, infliximab, and elemental diets have been tried but there is no definite treatment for secondary amyloidosis in Crohn's disease. Kidney transplantation may offer the best prospects for patients with Crohn's disease who develop amyloidosis and end-stage renal failure.
Fourteen barley cultivars were tested through 4-year trials at Tovarnik, Nova Gradiška, Požega and Osijek sites in order to explore interaction effects of genotype by environment using AMM1 and AMM2 ...models for grain yield and grain protein content. The results of analysis of variance showed statistically significant effects of year, location and cultivar on grain yield and protein content. The highest grain yields had cultivars Bingo (7.357 t/ha) and Barun (7.336 t/ha). The highest values of grain protein content had cultivars Vanessa (13.06%) and Prometej (12.94%), whereas the lowest values of grain protein content were obtained for cultivars Barun (12.14%) and Princ (12.29%). High stability of grain yield and protein content, together with high level of grain yield and lower level of protein content, was estimated for cultivar Barun. The stability of cultivar Barun was more expressed in relation to the year of testing than to the location. Related to location of testing, high interaction scores (IPCA1) were obtained for cultivar Vanessa with high average protein content. Cultivars Tiffany, Plaisant and Favorit had medium to higher interaction scores (IPCA1 and IPCA2) for grain protein content, and in case of AMMI2 analysis they didn't show specific relation to locations.
U pokusima s četiri sorte jarog ječma (Astor, Fran, Matej i Scarlett)
tijekom pet godina (2004.-2008.) na dva lokaliteta (Osijek i Nova Gradiška)
istraživan je interakcijski učinak sorte i okoline na ...urod zrna i količinu
bjelančevina u zrnu modelima AMMI1 i AMMI2.
Analizom varijance utvrđeni su značajni učinci godine i sorte na urod
zrna, dok su učinci godine, lokaliteta, norme sjetve i sorte značajno utjecali
na sadržaj bjelančevina. Interakcijski učinci dokazani su za urod zrna (godina
x lokacija, godina x lokacija x norma sjetve i godina x sorta), te za sadržaj
bjelančevina (godina x lokacija, godina x norma sjetve i godina x sorta).
Sorta Matej ostvarila je najviši urod zrna u provedenim istraživanjima, uz
nizak interakcijski skor IPCA1, a što ukazuje na visoku adaptabilnost ove
sorte uvjetima proizvodnje. Na biplotu se uočava povezanost ove sorte s
uvjetima proizvodnje lokacije Nova Gradiška - 2005. Sorta Scarlet, uz urod
zrna na razini prosjeka pokusa, vrlo visokog je interakcijskog skora IPCA1, a
što ukazuje na nižu adaptabilnost ove sorte uvjetima proizvodnje (lokacijegodine)
u provedenim istraživanjima. Sorte Fran i Scarlett, su sorte koje se
odlikuju nižim sadržajem bjelančevina, a u provedenim istraživanjima sorta
Scarlett je imala viši interakcijski skor IPCA1, a sorta Fran niži interakcijski
skor IPCA 1.
Na biplotu modela AMMI2 uočava se velika udaljenost sorti Astor, Matej
i Scarlett od ishodišta, što upućuje na nestabilnost ovih sorti za svojstvo
sadržaja bjelančevina te na značajan specifičan učinak okolišnih uvjeta na
sadržaj bjelančevina.
