The effect of long or chopped straw on pig behaviour.
In the EU, pigs must have permanent access to manipulable materials such as straw, rope, wood, etc. Long straw can fulfil this function, but can increase labour requirements for cleaning pens, and result in problems with blocked slatted floors and slurry systems. Chopped straw might be more practical, but what is the effect on pigs' behaviour of using chopped straw instead of long straw? Commer...
متن کاملeffect of supplemental dietary fat and processed barley grain on performance of lactating dairy cow
the effect of barley grain processing and source of supplemental fat on performance of lactating dairy cows were studied in a replicated 4 × 4 latin square design with 21-d periods and a 2 × 2 factorial arrangement. eight holstein cows with mean body weight (bw) of 572 ± 71 kg and 45 ± 10 days in milk were allocated to 4 dietary treatments including 1) ground barley with cottonseed 2) pelleted ...
متن کاملA comparison of microbial protein synthesis in beef steers fed ad libitum winter ryegrass or fodder beet
Microbial protein synthesis of steers (liveweight 286±9 kg) was compared with diets of ad libitum winter grass and fodder beet with 1 kg DM of lucerne silage. The experimental design was a four-by-two treatment comparison (experiment 1 and 2), using 11 day individual pen trials with total faecal and urinary collection. The trials assessed in vivo digestibility of diets, and diurnal variations i...
متن کاملDDT residues in beef cows fed apple pomace.
D RIED apple pomace and apple pomace silage have been fed successfully to ruminants (Hills, 1902; Lindsey et al., 1921; Walton and Bidwell, 1923; Holdaway, 1925; Atkeson and Anderson, 1927; Knott et al., 1932; Perkins and Monroe, 1935). I t has replaced all of the roughage normally used for wintering beef cows (Burris and Priode, 1957). However, in the past, apple pomace has contained up to 40 ...
متن کاملEffects of Physical Form of Barley Straw and Urea Supplementation on Intake and Digestion of Sheep Kept Under High Ambient Temperature
This research was designed to examine the effect of both physical form of the roughage (chaff or ground/pelleted) and or urea supplementation on intake, and digestion by sheep fed barley straw housed at high ambient temperature (40C). The experimental design was factorial 2 x 2 x 4. Sixteen Merino sheep, weighing 26.3 ± 2.1 (SE) kg were randomized into four groups (n=4). Each group was fed one ...
