Fattening Pigs

1. Voluntary feed intake, performance and carcass quality were studied with 20 individually housed pigs given isocaloric diets (2,770 kcal/kg. DM) containing either 8·9 % or 12·9 % crude fibre in the dry matter over the period of growth from 45 to 91 kg. live-weight.2. There were no significant differences between diets in voluntary feed intake, rate of gain or carcass quality.3. Apparent digestibility coefficients and rates of passage of the diets were determined in eight castrated male pigs. Rates of passage were not significantly affected by diet or live-weight when determined at 57 and 82 kg. live-weight.

Voluntary Intake

Disposal of sewage sludge to grassland is likely to increase in future years as a result of legislation to control disposal to the sea (CEC, 1991) and increased production (DoE, 1993). Recent research has investigated the possible accumulation of potentially toxic elements in body tissues of lambs given diets containing known amounts of sludge (Wilkinson et al, 1996). The aim of this experiment was to study the effects of season and method of application of sludge to grassland on voluntary feed intake, digestibility and growth of lambs.

The Uk

De-hydrated forages are often fed to equids in the UK in place of more traditional grass hay, particularly where individual animals are known to have a sensitivity to dusty, mouldy hay which may play a part inducing respiratory problems such as chronic obstructive pulmonary disease (COPD). One such alternative forage is short-chop de-hydrated grass. However, there is very little information available on voluntary feed intake (VFI), apparent digestibility and nutrient intake parameters when de-hydrated grass is offered to equids compared with traditional grass hay. This study examines the VFI and apparent digestibility in vivo of a short-chop de-hydrated grass compared with a traditional grass hay and determines their ability to meet the predicted energy and protein needs of mature ponies.Six mature Welsh-cross pony geldings with a mean liveweight (LW) of 281 kg (s.e.d. 0.89) were individually housed and offered ad libitum access to either short-chop de-hydrated grass (DHG) or traditional grass hay (HAY) plus 60 g/h/d minerals. The DHG and HAY were made from the same 2nd cut perennial ryegrass sward cut on the same day.
