Uticaj gustine naseljenosti na pojedine parametre dobrobiti brojlera - 2. različite gustine naseljenosti brojlera

Stocking density is considered one of the most important factors for the welfare of broilers. This paper is continuation of the study in order to obtain full evaluation of the impact of different broiler stocking densities on production performance, condition of the broiler legs and body feathering, as welfare indicators but also indicators of the productivity and quality of produced chickens. The effect of three stocking densities (20, 15 and 10 birds/m2) was investigated in 4 repetitions on broilers of genotype Hubbard at the age of 3 and 6 weeks. At the age of 6 weeks stocking density of 20 birds/m2 resulted in significantly lower growth of broilers, higher mortality and higher incidence of leg lesions and problems with body feathering, compared to stocking densities of 15 and 10 birds/m2.Gustina naseljenosti se smatra jednim od važnijih faktora za dobrobit brojlera. Rad predstavlja nastavak istraživanja u cilju potpunijeg sagledavanja efekata različitih gustina naseljenosti brojlera na proizvodne performanse, stanje nogu i telesnog pokrivača, kao indikatore dobrobiti ali i proizvodnosti i kvaliteta proizvedenih pilića. Ispitan je uticaj tri gustine naseljenosti (20, 15 i 10 grla/m2) u 4 ponavljanja na brojlerima genotipa Hubbard u uzrastu 3 i 6 nedelja. Gustina naseljenosti se, na osnovu ispitanih indikatora, ne može smatrati faktorom koji utiče na dobrobit pilića u uzrastu od 3 nedelje. U uzrastu od 6 nedelja gustina naseljenosti od 20 grla/m2 je rezultirala značajno manjim porastom brojlera, većim mortalitetom i većom frekvencijom pojavljivanja problema sa nogama i telesnim pokrivačem u odnosu na gustine od 15 i 10 grla/m2

The politics of performance: transnationalism and its limits in former Yugoslav popular music, 1999–2004

This paper examines transnational relations between the Yugoslav successor states from the point of view of popular music, and demonstrates how transnational musical figures (such as Djordje Balaševi?, Mom?ilo Bajagi?-Bajaga and Ceca Ražnatovi?) are interpreted as symbolic reference points in national ethnopolitical discourse in the process of identity construction. Another symbolic function is served by Serbian turbofolk artists, who in Croatia serve as a cultural resource to distance oneself from a musical genre associated by many urban Croats with the ruralization (and Herzegovinization) of Croatian city space. In addition, value judgements associated with both Serbian and Croatian newly composed folk music provide an insight into the transnational negotiation of conflicting identities in the ex-Yugoslav context. Ultimately the paper shows how the ethnonational boundaries established by nationalizing ideologies created separate cultural spaces which themselves have been transnationalized after Yugoslavia's disintegration

Effect of straw size and microbial amendment of litter on certain litter quality parameters, ammonia emission, and footpad dermatitis in broilers

This study was conducted to evaluate the impact of litter amendment (microbiological product &ndash; Micropan complex) and straw size (unchopped and chopped straw) on pH, moisture level, ammonia emission, and footpad dermatitis in broilers. A total of 1200 1-day-old Ross 308 broilers were randomly allocated to four treatments (2  ×  2 factorial arrangement), with four replicates per treatment. Each replicate consisted of 75 as-hatched birds per pen. The first factor consisted of wheat straw &ndash; chopped (<i>C</i>) or unchopped (<i>U</i>) &ndash; and the second factor was the litter amendment with (WM) or without (OM) Micropan^&reg; (enzymatic bacterial product &ndash; Eurovix, USA). At 4, 5, and 6 weeks of the trial, the levels of ammonia concentration, moisture content, and pH of litter in each pen were measured. The foot pad lesions were evaluated at 21, 35, and 42 days of age. Broilers reared on chopped straw had significantly better leg condition as expressed by a smaller incidence and severity of footpad dermatitis. The pH value of litter was decreased and footpad quality was significantly improved by Micropan application in broilers kept on chopped and unchopped straw in the sixth week of age. There was no significant effect of Micropan application and straw size on ammonia emission in broiler housing
