FATTENING CAPACITIES AND MEAT QUALITY OF JAPANESE QUAILS OF FARAON AND WHITE ENGLISH BREEDS

The aim of the study was to establish the fatting capacity and the meat quality of the combined (meat+eggs) White English breed and to compare with the same of the meat Faraon breed. Logically, the live weight of 31-day old male Faraon-birds was by 5,9 % higher and of the female ones – by 7,9 % compared to the birds of White English breed. Feed conversion ratio for the experimental period (3-31 days) for the White English quails was to 9,95% less effective, compared to the Faraon birds. The meat of Faraon quails contained more dry matter and protein compared to the meat of White English breed. Fat content in the quail bodies of White English breed was signifi cantly lower compared to Faraon breed /Р≤0,05/. Quail meat of White English breed was characterized by its better capacity for technological processing due to the lower loss of moisture – by 18,8 % for breast and 22,4 % for leg muscles /Р≤0,05/. The established results characterize the combined White English breed as suitable for producing both of eggs and meat from quails

The effect of the weaning age of rabbits on slaughter traits and physicochemical properties of meat was investigated. Sixteen New Zealand White rabbits (Oryctolagus cuniculus) were used, divided in two groups: group А (n = 8) - weaned at the age of 21 days (early weaned) and group В (n = 8) - weaned at the age of 35 days (normally weaned). The animals were fed with two categories of pelleted feed: for weaned rabbits up to 50 days of age and for growing rabbits older than 50 days of age. It was established that the early weaning of rabbits resulted in a statistically significantly lower body mass, dressed carcass weight and dressing percentage as compared to normally weaned animals. Also, the pH of meat by the 24th hour after slaughtering and the dry matter of m. longissimus lumborum (LL) were signififi cantly lower in group A. Simultaneously, a statistically significantly higher water-holding capacity, water content and lightness were established in the meat of early weaned compared to normally weaned rabbits. The protein and fat contents of LL and m. semimembranosus (SМ) in rabbits from group A correlated negatively and significantly with water content, and positively with the dry matter. In group B, water content also correlated significantly and negatively with protein content. Fat and ash in SM meat was in a positive statistically significant relationship for both experimental groups. The results from the present study showed that the weaning age influenced both the slaughter traits and physicochemical properties of rabbit meat.Istražen je učinak dobi odbijanja od sise kunića na klaonička i fizikalnokemijska svojstva njihova mesa. Šesnaest novozelandskih bijelih kunića (Oryctolagus cuniculus) bilo je podijeljeno na dvije skupine: skupinu A (n = 8) - odbijenu u dobi od 21 dan (rano odbijanje) i skupinu В (n = 8) - odbijenu u dobi od 35 dana (normalno odbijanje). Kunići su bili hranjeni dvjema kategorijama peletirane hrane: za odbijene kuniće do dobi od 50 dana te za tovljene kuniće starije od 50 dana. Ustanovljeno je da rano odbijanje dovodi do statistički značajno manje tjelesne mase, manje mase obrađenog mesa i manjeg postotka obrađivanja u usporedbi s normalno odbijenim kunićima. Vrijednosti pH mesa 24 sata nakon klanja i suhe tvari najdužeg leđnog mišića bile su značajno manje u skupini A. Istodobno je statistički značajno veći kapacitet zadržavanja vode i veći sadržaj vode bio ustanovljen u mesu rano odbijenih kunića u odnosu na normalno odbijene. Sadržaj bjelančevina i masti u m. longissimus dorsi i m. semimembranosus (SM) u kunića skupine A bio je u negativnoj i značajno većoj korelaciji sa sadržajem vode i pozitivnoj sa suhom tvari. Sadržaj vode u skupini B također je bio u značajno većoj i negativnoj korelaciji sa sadržajem bjelančevina. Sadržaj masti i pepela u mesu semimembranoznog mišića bio je u pozitivnom statistički značajnom odnosu u obje pokusne skupine. Rezultati istraživanja pokazuju da dob odbijanja od sise utječe na klaoničku obradu i fizikalnokemijska svojstva kunićjeg mesa

Логично на 31-дневна възраст живата маса на мъжките птици от породата Фараон е била с 5,9% по- висока, а при женските - със 7,9% в сравнение с птиците от породата Бели английски. Средно за опитния период (3-31 дни), конверсията на фураж при птиците от породата Бели английски е била с 9,95% по-неефективна в сравнение с тази при месодайната порода Фараон. Месото на птиците от породата Фараон е по-богато на сухи вещества и протеин - съответно с 8% при гръдната и 8,5% при крачната мускулатура сухи вещества и с 3,2% при гръдната и 4,6% при крачната мускулатура протеин. Съдържанието на мазнини в трупчета от породата Бели английски е достоверно по-ниско в сравнение с трупчетата на породата Фараон /Р≤0,05/. Месото на пъдпъдъците от породата Бели английски се характеризира с по-добра пригодност за технологична преработка, поради по-ниската загуба на влага – с 18,8% за гръдната и с 22,4% за крачната мускулатура / Р≤0,05/. Получените резултати характеризират породата Бели английски като подходяща за производство на яйца и месо от японски пъдпъдъци

Mixnets: Implementation and Performance Evaluation of Decryption and Re-encryption Types

The anonymous channels have been the essence of numerous protocols that include anonymous message passing between peers. The mixnet structure is one way to accomplish the anonymity . Since the publication of the Chaumian mixnet, there have been many practical implementations. There are two main approaches to implement mixnets: the decryption (Chaumian) and the re-encryption mixnets. In this paper we analyze four types of mixnets, from which one decryption and three re-encryption types. They were implemented in the Java programing language and evaluated on several criterias as: the number of messages, the total number of nodes, the number of threshold nodes, and the key length of underlying crypto system. In the results section we compare the results from the practical tests to answer the research question, which type of mixnets has better features

Meat quality and boar taint in entire male pigs fattened to 90 kg

Abstract. The aim of the present study was to investigate the chemical composition, technological traits and incidence of boar taint of meat from entire male pigs from two of the commonest breeds reared in Bulgaria: Landrace and Danube White. Fifty meat samples from entire male pigs (22 Landrace and 28 Danube White) fattened to average live weight of 90 kg were investigated. The chemical composition of Landrace pig meat was characterised with insignificantly lower fat and mineral content compared to Danube White meat. There were no significant differences between both breeds as technological properties of meat (pH, water holding capacity, and cooking loss) were concerned. The breed had a statistically significant effect on meat marbling (р<0.001). Landrace meat exhibited insignificantly higher incidence of the unpleasant boar taint as compared to Danube White meat (27.27% and 25.00%, respectively)
