Dietary Zn supplements for ruminants have traditionally been inorganic salts, such as zinc oxide (ZnO) or zinc sulphate (ZnSO4)
Tracking and locating wolves in the wild is possible using playbacks, according to the findings of a trial carried out by researchers at Reading University.
Walk-through enclosures provided positive enrichment for ring-tailed lemurs and encourage behaviour similar to that found in the wild.
Chickens did not regulate feed intake when fed using a sequential feeding schedule (diets of different nutritional value offered in cycles) over the medium term (day) on energy related to protein content.
A longer left shoulder in racehorses means the horse is likely to be classified as anticlockwise, while a longer right shoulder means the horse is significantly more likely to prefer the clockwise direction and the same can be said for fore limb length.
Using an electronic heart-rate monitor to assess horse fitness and response to exercise proved to be a useful tool in recent trials at Reading University – good news for trainers and owners without specialist facilities.
Controlled fermented lucerne had a positive impact on the digestible energy (DE) of high grain, racing-type diets, thus increasing the supply of energy to racing horses.
Lying behaviour was not affected by the range of housing treatments used in a trial by Australian scientists, but the role of lying behaviour in the welfare of horses needs to be clarified.
Take Home Message: Exposing ewes to parasites does not affect mean lamb birth weight, but reduces lamb weight gain in the first 5 weeks post lambing and increases lamb weight gain during lamb exposure to parasites.
The expression of immunity to parasites in immune ewes is nutritionally expensive and body reserves may be sacrificed over reproductive [...]
Traditional British and New Zealand lambs are similar in performance for birth assistance and lamb vigour traits, but high index-selected lambs required more assistance at birth than NZ lambs.
