The aim of this work was to study the effect of different housing systems (wire-net cage vs pen; 0.15 m2 per rabbit) and gender (male vs female) on the growth performance and carcass traits of fattening rabbits. A total of 110 Hyplus rabbits (PS 19 × PS 39) of both sexes (1:1) were weaned at 36 days of age (on average 908±11 g). The rabbits were provided with a standard fattening diet. They were randomly divided into 4 experimental groups (by housing system and by gender). The final rabbit’s live weight (at 80 d of age), as well as daily weight gain were affected by the housing system (P≤0.001) and gender (P≤0.05). Feed intake and feed conversion ratio were not affected by housing systems and gender. The females (gender effect) and cage-housed rabbits (housing system effect) showed the higher slaughter weight (P≤0.05) compared to other rabbits. There was a higher hind part to reference carcass ratio in females (by +1.0 percentage points; P≤0.05) than in males. There was a higher hind part to reference carcass ratio in pen-housed rabbits (+1.6 percentage points; P≤0.001) than in cage-housed rabbits. Similarly, the pen-housed rabbits demonstrated the both significantly higher thigh to reference carcass ratio (+0.7 percentage points) and thigh muscle to reference carcass ratio (+0.5 percentage points). It can be concluded that regardless of gender, the productive performance was better in cage-housed rabbits. The housing of rabbits in the pen affected the carcass characteristics in a beneficial way. This research was supported by the Ministry of Education, Youth and Sports of the Czech Republic (‘S’ Project) and Ministry of Agriculture of the Czech Republic (Project No. MZER00714).

The present study was conducted to investigate whether monochromatic light affect feed intake, egg production and egg quality of laying hens. In this study, it was used white and green fluorescent lamps to illuminate Brown-Nick hens for 8 wk. Light sources were equalized to a light intensity of 15 lx. 47 weeks old layers were divided into 2 groups of similar mean weight comprising 16 birds each and housed in individual cages. A 16:8 hours light:dark photoperiod was employed. The birds were housed in an air-conditioned room at a conventional ambient temperature (15-25 °C) with a relative humidity of 50-60% for 24 h per day. Laying performance was assessed by recording feed intake, egg weight, egg production daily and egg quality weekly of the experiment. The results indicated that green light application did not have significant (P>0.05) effects on feed intake, feed conversion efficiency, egg production, total number of eggs, total egg weight, average egg weight and egg quality criteria on laying hens. However, the green light application affected egg yolk colour a (redness) (P<0.01) and b (yellowness) values (P<0.05). The results suggest that green light application may improve egg yolk colour score of laying hens.
