| The objective of the present study was to compare the colour, chemical composition, meat quality and fatty acid profile of the longissimus dorsi (LD) muscle of growing bulls housed in an insulated tie-stall, an uninsulated barn or a forest paddock. Two housing experiments were conducted at the North Ostrobothnia Research Station of MTT Agrifood Research Finland in Ruukki (64°44’N, 25°15’E). The first experiment was conducted from November 1999 to October 2000 and comprised 30 Hereford bulls, the second from November 2000 to December 2001 with 30 Ayrshire bulls. In both experiments the bulls were divided into six groups of five animals according to live weight and the groups were randomly allotted to one of three treatments: tie-stall in an insulated barn... |

| Training cattle to avoid electric fences before turnout to grazing reduces the risk of the animals breaking out from their paddock. We investigated the time needed for dairy bull calves to learn to avoid a light-built electric fence. Nineteen dairy bull calves were trained to an electric fence in a training yard during seven days. The number of electric shocks the animals received from the training fence was recorded continuously. After the training period, the calves were turned to pasture. Nine of the animals were also grazed the following summer as yearlings, and observed before turnout in a smaller enclosure. The calves got more shocks from the fence during training hour 1 than during any of the following seven hours. The number of shocks the calves... |

| The objective of the present study was to compare the performance of Hereford bulls in an insulated tie-stall, an uninsulated barn and a forest paddock in Northern Finland (Ruukki: 64°44’N, 25°15’E). In November 1999, thirty Hereford bulls (age 6.8±0.5 (mean±SD) months; live weight (LW) 285±35 kg) were divided into six groups of five animals according to their LW and the groups were randomly allotted to one of three treatments: tie-stall in an insulated barn (IB bulls, ten animals in individual stalls), pen in an uninsulated barn (UB bulls, 5 animals per pen, two pens) and forest paddock (PAD bulls, 5 animals per paddock, two paddocks). The experiment ended in October 2000, when the bulls were 18.3±0.5 months of age and 772±51 kg LW. During the entire... |
