Aline Dos Santos Neutzling: Predicted and true herd development over ten years by applying a bio-economic model to village cattle in South-western Niger. Ms. Neutzling gave a presentation about the cattle development of 40 households in Niger between 1998 and 2008. This development was predicted with a computer model (PRY Herd Life) using stochastic and deterministic modeling with fixed input parameters. The model predicted that there would be 153 heads of cattle in 2008; there were 151 heads, so a good simulation. The model did not perform well for the herd structure, this might have been caused by the fact that the model only has 7 culling strategies to choose from and that this is fixed for the entire time period. Faradilla Attamimi: Bali Cattle Performance in Smallholder Mixed Systems of Indigenous and Transmigrant Farmers on Ceram Island, Indonesia The Indonesian government chose the Balinese cattle herds to produce the majority of the meat for the growing demand in the Maluku, North Maluku and Papua provinces. The cattle population cannot deal with the high pressure and now the cattle numbers are decreasing. This study was done to see if there is a difference in the performance of the management system of the native farmers vs. that of the transmigrated farmers. There was found no relationship between the two performance types just between the different areas on Bali, so there are other factors playing a role in the change in performance of cattle on Bali. Simon Riedel: Variation in Reproductive Performance of Sows Kept by Smallholder Farmers in Xishuangbanna, Southern China. This research on pig production provided the researchers with surprising and unexpected results. They expected that the pig production in rural China was different at various altitudes in the area. However they found no relation between the average reproduction performance of the pigs on different altitudes. The researchers now suspect that the difference in performance is related to the pigs diet.
