FATTY ACIDS COMPOSITION OF POULTRY MEAT PRODUCED IN INDOOR AND OUTDOOR REARING SYSTEMS
No full textThe research was carried out on chickens of Ross 208 provenience, which were divided into two groups. Chickens reared outdoor had statistically significantly higher portion of α-linolenic acid (P<0.05), linoleic and arachidonic acid, as well as higher total of PUFA n-6 acids (P<0.01) than chickens that were kept indoor. However, these chickens had higher portion of myristic and palmitic acid (P<0.01), as well as DHA (P<0.001) in the lipids of breast muscles. There was also higher content of myristic and linoleic acids (P<0.01) determined in the lipids of thigh muscles of chickens reared indoor, while chickens kept outdoor had higher content of EPA (P<0.01), palmitic, stearic and arachidonic acids (P<0.001). Chickens of the 2nd group exhibited more favorable ratio of PUFA n-6 / PUFA n-3 in the lipids of breast muscles. The same ratio for the lipids of thigh muscles was better in the 1st group
INTENSITY OF ATTACK OF BOTRYTIS CINEREA PERS. EX FR. ON THE CV. GRAŠEVINA AND TRAMINAC GRAPES AND THE EFFICIENCY OF BOTRYTICIDES
No full textBotrytis gray mold caused by Botrytis cinerea is an important pathogen of grapevines all over the world. In order to determine the intensity of B. cinerea attack on mature grapes and efficiency of botryticides (cv. Traminac - iprodion, pyrimethanil, fludioxinil + cyprodinil; cv. Graševina - fenhexamid, fludioxinil+cyprodinil, tebuconazol+diclofluanid) a two-year experiment (2001-2002) was set up on locations Mladice (Traminac) and Škomić (Graševina). By evaluation of the intensity of B. cinerea infection on the Graševina and Traminac grapes the strongest infection determined on the control, and the weakest on the variant with botryticides Switch. Comparison of infection intensity on the Traminac grapes with the Graševina grapes led to no differences concerning the sensitivity of varieties. The disease intensity primarily depended on climate conditions. Both experimental years were charactized by the quantity of precipitation in the vine-yards which were in favour of the high humidity allowing high disease intensity
DINAMIKA POPULACIJE NEMATODA U PŠENICI
No full textNa području Kneževa u Baranji, tijekom 2000./2001. godine, proučavane su nematode na ozimoj pšenici pri standardnoj obradi tla. Praćena je dinamika populacije nematoda u pšenici, od jeseni (sjetva pšenice) do konca vegetacije pšenice. Rezultati su pokazali kako je ukupna brojnost nematoda i rodova očekivano rasla razvojem vegetacije pšenice. Broj nematoda bio je najmanji u listopadu, a najveći broj zabilježen je u travnju. Slična je bila i dinamika ukupnog broja rodova, najmanje rodova utvrñeno je u listopadu, a najviše u ožujku,do kraja vegetacije broj rodova se smanjio. Populacija fitoparazitnih nematoda bila je najveća u jesen, a
najmanje u proljeće. Dinamika populacije bakterivora rasla je tijekom vegetacije. Tako je u listopadu bila minimalna zastupljenost od 10 % bakterivora u odnosu na druge trofičke grupe. Brojnost bakterivora najvišu razinu dosegla je krajem vegetacije. U svibnju su 65 % nematoda iz uzorka tla činile bakterivore
INFLUENCE OF Ca-FOLIAR APPLICATION ON YIELD AND QUALITY OF SWEET PEPPER IN GLASSHOUSE CONDITIONS
No full textCalcium is an extremely important nutrient in highly productive fruit growing such as glasshousegrown sweet pepper. Good bioavailibility of calcium can be achieved by calcisation, but in many cases owing to its high prices, long-term effects, along with a delayed initial effect, as well as problems that appear due to radical change in
availability of other nutrients in soil, its application is restricted. This paper deals with research on effects of foliar applications of the commercial chemical named "Calciogreen", as a supplement to the standard fertilization in greenhouse growing, on yield and quality of pepper fruits of the Cecil cultivar in the region of East Croatia
RASPODJELA SJEMENA PŠENICE PO POVRšINI I DUBINI U IZRAVNOJ SJETVI
No full textTijekom istraživanja postavljen je sjetveni pokus na dva pokušališta na površinama PZ “Jankovci” u Vukovarsko-srijemskoj županiji. Istraživana je uzdužna i poprečna raspodjela sjemena te raspodjela sjemena po dubini. Analiza navedenih raspodjela obavljena je nakon nicanja usjeva, a dobiveni podaci obrañeni su i prezentirani standardnim znanstveno-statističkim metodama, uz podršku programskog paketa EXCEL 5.0. Rezultati istraživanja ukazuju na nezadovoljavajuću raspodjelu sjemena po površini (uzdužna i poprečna) i dubini, što je podudarno s dosadašnjim istraživanjima. Dakle, izravnom sjetvom pšenice štedi se energija, povećava se produktivnost rada, obavlja se sjetva u kraćem i optimalnom roku u odnosu na konvencionalnu sjetvu, ali i nadalje ostaje problem nezadovoljavajuće raspodjele sjemena
INFLUENCE OF SEX ON LIPIZZANER BREED FOALS DEVELOPMENT
No full textThe offspring’s development especially in the first months after foaling is crucial for further development. If favourable conditions of feeding, keeping and fancying as well as other important conditions are ensured, a homogenous growth and development of the offspring is obtained. Research was conducted on 44 male and 42 female Lipizzaner breed foals in the first six months after foaling. The measuring of the withers height, chest girth and cannon bone circumference were done seven days after foaling and at the age of six months. Measuring data were processed by the statistical program SPSS/PC (Nie et al., 1975). The processed data of
the obtained measurings indicate homogeneity for both male and female foals. The male foals had a little higher values than the female in both measurings, but the differences between sexes were highly significant only in the cannon bone circumference. Correlations among obtained values were positive and ranged between low and very high, with correlation coefficients between r= 0.379 and r=0.843 for male and r=0.338 and r=0.723 for female foals. The differences between the obtained values were significant and highly significant and a little more marked in male foals
