The aims of this study were twofold: to assess the welfare of two hybrids of laying hens in conventional cages and to investigate the effects of tier’s level on the integument condition and fearfulness. Two commercial hybrids, white Lohmann Selected Leghorn (LSL) and brown Lohmann Traditional (LT) at about 18 weeks of age were used in the current study and were housed at three hens / cage. No birds were beak-trimmed. External appearance of the body (scoring of plumage condition and skin injuries at body parts and comb), heterophil-lymphocyte (H-L) ratios and duration of tonic immobility (TI) were used as indicators of well-being. LSL birds showed better plumage condition and low H-L ratios than LT birds while no significant difference was recorded in TI test between the two hybrids. Hens housed in the top tier showed worse feather condition and more wounds than birds in middle and bottom tiers whereas for fear levels, no significant difference was revealed for hens from different tiers of cages. These results suggest that the welfare of LSL birds was relatively good compared to LT. Therefore, conventional cages can be used by the hens to a large extent if birds are properly selected to be specifically adapted to cages.

This study was carried out in Sids Agricultural Research Station belonging to Animal Production Research Institute in Beni-Suef governorate on a total number of forty apparently healthy ewe lambs with average weight of 28±0.5 kg to clarify the effect of shearing as a stressor on comfort, feeding and social behaviour and blood cortisol level. Ewe lambs were divided into three groups, the first one (n=10) is shorn at spring, the second (n=10) is shorn in autumn and the third (n=20) is kept as a control. Results showed that there was no significant difference in patterns of comfort behaviour between shorn and unshorn ewes except for grooming behaviour which was significantly (p<0.01) increased in shorn than unshorn groups. Blood cortisol level was significantly (p<0.05) higher in ewes shorn in spring and autumn at time of shearing (zero minute) than pre-treatment (-20 minutes) and post-treatment time (3 hours following shearing). So the cortisol measurements is a useful indicator of short-term stresses from handling or husbandry procedures such as shearing.

This study is to develop a new scoring system for rating Hazard analysis and critical control points prerequisite evaluation items for meat shops to provide a more objective and accurate evaluation of food safety compliance. The importance of each item was measured by looking at the hazard severity level and the rate of non-compliance associated with it. It was found that the new scoring system is more stringent and gives a clearer picture of compliance with the most critical safety standards, and therefore is expected to have a positive effect on the hygiene and safety of livestock products.
