The effects of early separation on the dairy cow and calf
Contributor(s):: Flower, F. C., Weary, D. M.
Most dairy producers believe that early separation of the cow and calf is necessary for reproductive efficiency, to minimize health problems and to improve the ease of milking. In addition, many consider that it is less distressing for both animals if separation occurs earlier rather than later....
The impact of genetic selection for increased milk yield on the welfare of dairy cows
Contributor(s):: Oltenacu, P. A., Broom, D. M.
Milk yield per cow has more than doubled in the previous 40 years and many cows now produce more than 20,000 kg of milk per lactation. The increase in production should be viewed with concern because: (i) the increase in milk yield has been accompanied by declining fertility, increasing leg and...
The locomotion of dairy cows in passageways with different light intensities
Contributor(s):: Phillips, C. J. C., Morris, I. D., Lomas, C. A., Lockwood, S. J.
Guidelines for the housing of dairy cows do not address the provision of supplementary lighting in passageways, other than for inspection of the animals. Two experiments were conducted to investigate whether lighting passageways to various intensities influenced the locomotion of dairy cows. The...
Time budgets and adrenocortical activity of cows milked in a robot or a milking parlour: interrelationships and influence of social rank
Contributor(s):: Lexer, D., Hagen, K., Palme, R., Troxler, J., Waiblinger, S.
Adrenocortical activity and time budgets in a robotic milking system in two variants of cow traffic (partially forced, free) were compared with a conventional milking system, focusing on the relationships between adrenocortical activity, time budgets, and social rank of the cows. Both groups were...
Welfare assessment on Japanese dairy farms using the Animal Needs Index
Contributor(s):: Seo, T., Date, K., Daigo, T., Kashiwamura, F., Sato, S.
The Animal Needs Index (ANI) is used for on-farm assessment of welfare in Austria. However, no synthetic welfare assessment system exists in Japan. We performed a welfare assessment of Japanese dairy farms using the ANI scoring system. On 25 farms, 36 dairy herds were assessed using the...
Behaviour to the human as a individuality of the milking cows
Contributor(s):: Shuji, Y.
The importance of dairy cattle behaviour towards humans was examined. 17 milking cows of Niigata University Muramatsu Station were investigated. The behaviours to one human inside of cowshed and in the pasture were examined. Responses to the behaviour which the human did to the cows, the...
Voluntary behaviour and passive response toward a human of the milking cows
The behaviour of 16 milking cows of Niigata university Muramatsu Station towards a human voluntarily was examined the human sat on the pasture and when the human stood up. Furthermore, relation between the voluntary behaviour and the passivity behaviour of each individual were examined. As a...
Long-term effect of housing method during the first three months of life on human-animal relationship in female dairy cattle
Contributor(s):: Mogensen, L., Krohn, C. C., Foldager, J.
To investigate the effect of housing during the first 3 months of life to the end of the first lactation on the human-animal relationship and milk production, 80 female dairy calves were housed either in open single pens (SOpen), closed single pens (SClosed), calf-groups (GCalf; 5 calves per...
Animal health and welfare aspects in organic dairy production systems - experienced practice during conversion to organic farming. (DARCOF Report No. 2)
Contributor(s):: Vaarst, M., Thamsborg, S. M., Kristensen, E. S.
A synthesis of knowledge project was carried out during the late summer 1998 to June 1999 with the objectives to describe the conversion to organic farming as experienced by people connected to the dairy herd (the farmers themselves, their veterinarians and agricultural advisors). Special focus...
Evaluation of the relationship between milkers and dairy cows and its effect on animal welfare
Contributor(s):: Salaberry, X., Huertas, S., Cesar, D., Piaggio, L., Gil, A.
Animal fear towards people can be very stressful, making animal handling difficult and dangerous. The way animals are handled, absence of food, milking parlour conditions and presence of human beings constitute a special stimulus to the animal. If it is positive, fear diminishes and the capacity...
Human-cow interactions: production effects
Contributor(s):: Grandin, T.
Behaviour of cows towards herdsmen is reviewed, with reference to fear memory formation; place-specific fear; introducing heifers to the milking parlour; effect of veterinary treatment; memory; locking of stanchions and stress.
The influence of the human-animal interaction in the milking parlour on the behaviour, heart-rate and milk yield of dairy cows
Contributor(s):: Knierim, U., Waran, N. K.
This study addressed questions regarding the quality of human-cow interactions in the modern milking parlour, and whether in this situation cows still react differently to different milkers.
Welfare assessment in cattle in two housing systems
Contributor(s):: Brule, A., Lequenne, D., Capdeville, J., Botreau, R., Veissier, I., David, V.
This study specifically focused on the welfare of dairy cows, as the first step towards a practical tool to assess some aspects of animal welfare on farms. First, 12 indicators were recorded in ten Prim'Holstein dairy farms (five free-stall housing and five tie-stall housing). Measurements were...
Welfare implications of dairy calf and heifer rearing
Contributor(s):: Lawrence, A. B., Dwyer, C. M., Jarvis, S., Roberts, D.
In this chapter we have focused primarily on behavioural issues that emerge from current practices of calf rearing. We have used the perspective of behavioural development and existing knowledge from other species to emphasise that early events in the calf's life (early weaning and individual...
