The aim of the study was to investigate the effects of transport time up to 12 h on welfare of bulls and cows. Cattle transport vehicle was used for the experiment. Sensors to measure temperature, relative humidity and video camera to monitor behaviour were mounted in observation pen. Eighteen measurements were performed during summer and winter for 4, 8, and 12 h transport time with three replications. To determine cortisol, glucose, lactate, and creatine kinase concentrations, blood samples were collected before and after transport from 80 bulls, 82 cows and 20 control animals. Cortisol concentration was generally inversely proportional to transport time (P < 0.001). Glucose concentration for cows was the highest at 12 h and the lowest at 8 h and for bulls it increased with transport time (P < 0.002). Lactate level generally correlated with transport time (P < 0.001), but for bulls the highest and the lowest were at 8 and 4 h in winter. Creatine kinase concentration positively correlated with transport time for bulls and cows but at different rates. Loss of balance and swaying strongly correlated with transport time (P < 0.002). Based on behaviour, stress hormones and pH values, an increase from 4 to 8 h had a higher effect than from 8 to 12 h transport time on welfare and subsequent meat quality.

In the agricultural sector, it is important to appropriately develop livestock resources in of developing countries in order to reduce poverty. The aim of this study was to investigate the animal handling and welfare issues during transport for marketing with special focus on cattle flow to and from Gudar livestock market and activity chain of Ambo abattoir in Ethiopia. Information and data on main feeder markets to Gudar regional market; the main stakeholders in this animal supply chain; number of animals flow to and from Gudar market; the distance and time duration the animals transported; animal handling and welfare concerns during transport and at market site; and activities in Ambo abattoir chain were gathered, interpreted and discussed. The study indicated that the flow of cattle to and from Gudar market was by walk- ing which took up to 4 days or by vehicles which took up to 3 h. There were no appropriate vehicle and loading facili- ties and animal handling conditions were poor. From total number of animals supplied to Gudar market about 7.6% died, 6.9% injured and 2.8% was stolen during transport. During transport from Gudar to final destination by walking, about 16% died and 10.7% was injured. The effect of animal number (p = 0.0498) was slightly significant than the effect of travel distance (p = 0.3487) on the occurrence of incidences such as animal death and injuries, at significance level of 0.05. Lameness and injury to bone, muscle, swelling of leg and sickness were widely observed during transportation by walking. Poor market infrastructures; lack of regional abattoir facilities; difficulties in getting timely market information; and lack of well-organized networks between stakeholders were also identified as existing problems compromising the animal welfare and economic benefits. Therefore, further research works concerning animal welfare during animal flow in the supply chain; and impact of abattoir activities on environment and human and animal health should be conducted. Such studies important to improve the economic benefits gained from livestock resources with positive contribution towards efforts of insuring food security and sustainable development
