Abstract
Pri treh slovenskih tradicionalnih pasmah kokoši lahkega tipa (slovenski rjavi kokoši, slovenski srebrni kokoši in slovenski grahasti kokoši) smo proučevali nesnost in kakovost jajc. V 18. tednu starosti smo v individualne kletke trinadstropne baterije vselili po 162 jarkic vsake pasme. V obdobju od 20. do 72. tedna starosti smo spremljali nesnost, porabo krme, telesno maso ter vitalnost kokoši. Vsake 4 tedne smo merili fizikalne lastnosti jajc. V nesnem obdobju je bila slovenska rjava kokoš najlažja in je znesla največ jajc, 301 jajce letno oz. 5,63 jajc tedensko. Najmanj krme je dnevno porabila slovenska rjava kokoš (119,9 g), ki je tudi najbolje izkoriščala krmo in sicer le 2,4 kg krme/kg jajčne mase in 145,0 g krme/jajce. Najtežja jajca so nesle slovenske srebrne kokoši (64,33 g), največ jajčne mase na leto so proizvedle slovenske rjave kokoši (18,40 kg). Jajca slovenske srebrne kokoši so imela najdebelejšo lupino (0,37 mm). Višina gostega beljaka in število hughovih enot sta bila pri slovenskih srebrnih kokoših večja kot pri ostalih dveh pasmah. Največ krvnih in mesnih peg smo našli v jajcih slovenskih rjavih kokoši (41%), ki so bile tudi najvitalnejše, v nesnem obdobju jih je poginilo le 3,1%.

Abstract:
Production traits and egg quality among Slovenian Brown hen, Slovenian Silver hen and Slovenian Barred hen were compared. At 18 weeks of age we encaged 162 hens of each breed in individual cages of 3 deck-batteries. Egg production, feed consumption, body weight and vitality of hens between 20 and 72 weeks of age were recorded. Every 4 weeks physical characteristics of the eggs were measured. During laying period Slovenian Brown hens were lightest, and had the most eggs (301 eggs per year, 5.63 eggs per week). The Slovenian Brown hen had the lowest daily feed consumption (114.0 g) and the best feed conversion efficiency (2.4 kg of feed/1 kg of egg weight and 137.9 g of feed/egg). The haviest eggs were laid by Slovenian Silver hen (64.33 g). The most egg mass per year was produced by Slovenian Brown hen (18.40 kg). Slovenian Silver hen laid eggs with the thickest egg shell (0.37 mm). The highest albumen height and the number of Haugh units were observed in Slovenian Silver hens compared to the other breeds. The most frequent blood and meat spots were recorded in eggs of Slovenian Brown hen (41 %), which also showed the best vitality - only 3.1% hens died during their laying period.

Keywords:laying hens, light type, traditional breeds, production, eggs, physical traits, Slovenia
