Transportation is often considered as one of the main causes of stress raising considerable interest, both in animal welfare and economic fields. Stressful transportation of camel may cause severe welfare consequences and economic losses. Therefore, this study was conducted to assess the stress resulting from transportation of Dromedary Camel (Camelus dromedarius) by measuring some behavioural and physiological responses. Camels were imported from Dongola quarantine in Sudan to Arqueen (at the borders between Egypt and Sudan) by walking for about 450 km. After that, camels are transported from Arqueen to Abu Simble quarantine in Aswan. According to method of transportation, camels were randomly assigned into three groups; group 1 (camels were transported by trucks for about 150 km, taking about 2-3 h), group 2 (camels were transported by walking for about 90 km, lasting for about 24 h), and group 3 (non-transported camels). In Abu Simble quarantine, 30 healthy males (5-7 years and 300-400 kg b.wt.) were selected for each group (three replicates for each). Some behaviours were selected from the ethogram and are used in the analysis which include comfort (recumbency and standing), ingestive (feeding and rumination), eliminative (defecation and urination) and body care (rubbing, scratching and nipping). All behaviours were recorded in the morning and afternoon by direct personal observation for 60 min with an interval of 5 min and calculated as a frequency per total observation time. Furthermore, blood samples were collected just after arrival of camels (T0) and at 18 h after arrival (T18) for hematological examination (PCV%, total RBCs and WBCs) and measurement of some blood parameters including total protein, albumin, globulin, glucose and cortisol. The results revealed that the frequency of standing, feeding, defecation, urination, scratching and total body care behaviours, were significantly decreased in group 1 (81.24, 33.51, 6.48, 9.12, 3.87 and 12.80) and group 2 (10.80, 31.67, 1.40, 2.19, 1.25 and 10.96) including transported camels in comparison to control group (97.26, 47.62, 12.16, 16.44, 12.88 and 21.06) respectively. The frequency of recumbancy was increased in transported groups as compared to control one. The results of haematological examination indicated that there is a significant increase in PCV% and neutrophil count and a significant decrease in lymphocyte count in groups 1 and 2 as compared to control one. Camels transported by trucks had a significant high level of cortisol at T0 (17.21 µg/dl) and T18 (6.14 µg/dl) in comparison to other groups. In conclusion, transportation of camels either by trucks or walk imposes a marked stress upon them as indicated by behavioural and physiological measures.

The twinning rate in a herd of Holstein dairy cattle and its effect on lactation and calf performance was investigated by using records of 5815 calving events. Data from twin calving Holstein cows in (TEC-DAP) farm in Al-Fayum Governorate between January 1997 and April 2008 were compared to those giving singles to study the differences in subsequent milk yield, previous and subsequent lactation and dry period length, as well as calf performance. The obtained average twinning rate was 1.4% during the period of the study. Cows giving twins had a significantly (p<0.01) lower daily, peak and 305-d milk yields than those with singles. There was no significant difference (p>0.05) in previous and subsequent lactation and dry period length between cows calving twins or singles. Calves born as twins were significantly (p<0.005) lighter at birth and weaning time than single calves, whereas total birth weight and total weaning weight were significantly (p<0.005) increased for twins than singles. Daily body weight gain from birth to weaning was significantly lower (p<0.005) for twin than single calves. Twinning in dairy cattle has a negative depressive effect on subsequent milk yield. Calf weight produced at weaning per cow calving can be increased in cows producing twins relative to cows producing singles. Alleviation of twinning constraints including dystocia, reduced calf survival and low reproductive performance requires improved management practices and early diagnosis of cows gestating twins in order to provide higher nutritive requirements in the last trimester of gestation and proper timing of drying off, and for higher assistance requirements at parturition. Thus, due to the increased disadvantages which did not offset the additional returns earned by calves, twinning in dairy cattle via selection or artificial induction appears not to be desirable.

This study was conducted in six dairy farms in Beni-Suef Governorate representing the most prevalent systems of housing and management in Egypt to assess the welfare and health of dairy cows kept in these systems. These systems including 1) tie stall barn with daily access to an outside shaded area associated with hand milking twice daily; 2) loose housing in partially sheltered yards on earthy floor represented by 4 farms with different management practices include feeding and milking, and 3) free stall barn with daily access to partially sheltered yards during the day time associated with three times daily milking in a parlour system. Each farm was visited three times over a period of one year. All cows were observed for lying and standing up behaviour and examined for lameness, mastitis, skin alterations at the knee and hock joints and rest of the body, teat injuries, cleanliness of the hind legs and udder, and body condition score. Results revealed that no restriction for lying and standing up behaviour was observed in all systems indicating that cow comfort was maintained. The prevalence of lameness was higher in loose housing system on earthy floor (0.9, 15.4 and 8.7 %). The prevalence of skin alterations at the knee joint was higher in cows kept in tie and free stall barns (4.7 and 7.5 % respectively) and at hock joints (11.9 %) in tie stall barn on concrete floor. Tie stall system had a higher prevalence of teat injuries (14.3 %) than other systems. High degree of dirtiness of hind legs (90.5, 89 and 99.2 %) and udder (91.4, 91.6 and 100 %) was found in loose housing system associated with increased dampness of the floor and lack of daily cow cleaning regimen.
