An experiment with two groups of 24 cows during weeks 3 to 22 of lactation examined the
influence of 7 (L) or 11 (H) kg concentrates per day on the prevalence of lameness. Grass
silage was offered ad libitum. The cows were scored on a 1 to 5 scale for their locomotion on …

Objective methods are required to assess the welfare of livestock in different environments.
Two experiments were conducted to determine comparative indicators of welfare in the two
most common loose-housing systems for dairy cows, strawyards and cubicles. Experiment I …

Calves were either isolated, spatially but not visually, or group-reared for eight months and
then kept together. Rank orders based upon competitive interactions were similar at eight
and 20 months. Almost all group-reared animals were higher in rank than all isolation …

The concentrations of progesterone in plasma, whole milk or fat-free milk taken 21 days after
AI and at other times have been used to diagnose pregnancy in about 500 Friesian heifers
and cows. Those cattle diagnosed not pregnant (15–35%) by this method were in 95–100 …

In an experiment during weeks 3 to 26 of lactation, two groups of 12 cows were offered a
mixed concentrate/grass silage diet containing 161 g crude protein per kg dry matter, and
two similar groups a diet containing 198 g crude protein per kg dry matter. The concentrate …

Two experiments were conducted to study the effects of two space allowances and two initial
milk yield levels on indicators of welfare relating to behaviour, performance and health of
dairy cows housed in strawyards (experiment 1), and cubicles (experiment 2). The …

A review.

During weeks 3 to 26 of lactation, two groups of 24 cows were offered either a 60: 40 (high)
or a 40: 60 (low) ratio of concentrate dry matter: silage dry matter. The 40: 60 diet was
restricted to give the same daily metabolizable energy and crude protein intake. The hooves …

In the first experiment, the digestibility of diets containing ratios of 1: 1 and 1: 4 hay to
concentrates was determined at five levels of feeding in castrated male sheep. With diet 1.1,
increasing the daily dry matter intake from 600 to 1400 g resulted in a linear decline in …
