The Effect of Urea Treatment of Straw and Lupin Supplementation on Intake, Liveweight Changes and Wool Growth in Sheep
نویسندگان
چکیده
Chaffed wheat straw was treated with a seven per cent solution of urea and sealed for three weeks before feeding to sheep. Mature wethers received either this urea-treated straw or straw that had received an equivalent amount of urea mixed in with it at feeding. Both straws were fed either with or without lupins at 200 g/hd/d for seven weeks. DM intake was increased both by the urea treatment and by lupin supplementation compared with the urea-supplemented straw, but animals on all treatments lost weight throughout the experiment. Urea treatment had no significant effect on either liveweight change or wool growth compared with the control animals. Lupin supplementation decreased the rate of liveweight loss by 93 g/hd/d, and also increased wool growth by 18% ( + 0.51 g clean wool/hd/d) on both basal diets.

Comparison of feeding value of a treated sea plant, Posidonia australis, with lucerne, pasture and wheat
An experiment was carried out to compare the effect of feeding posidonia australis as a non-conventional feedstuff with cereal straw for sheep maintenance; and to compare seagrass/chicken litter with lucerne hay and pasture for sheep production on a scale such as would be applicable to lot-feeding of sheep in the area of suthern Australia in case of short term feed scarcity. To approach this ta...
متن کاملWool growth in Merino wethers fed lupins untreated or treated with heat or formaldehyde, with and without a supplementation of rumen protected methionine
Lupins were treated by either heat (1158C for 1 h) or by formaldehyde (0.4 g 100 gÿ1 crude protein). The fractional rate of disappearance of N from dacron bags suspended in the rumen of steers was reduced by either treatment. Assuming a rumen outflow rate of 0.03 hÿ1, effective rumen degradability was 0.96, 0.94 and 0.92 for protein and 0.84, 0.82 and 0.81 for dry matter in untreated, heatand f...

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 ...

Forty ewes (3-6 years of age, average weight 41.2 kg)were randomly chosen from the flock of the sheep experiment station of Tripoli University. Ewes were divided into two groups, control group (C) received untreated barley straw and treatment group (T) received barley straw treated with 10% urea solution applied as 40% (V/W). Barley straw was sprayed with molasses when fed to animals. Both grou...
متن کاملEffect of Supplementing Common Reed (Phragmites australis) with Urea on Intake, Apparent Digestibility and Blood Metabolites of Baluchi Sheep
To evaluate the effects of treating or supplementing common reed (Phragmites australis) with 2% urea on intake, nutrient apparent digestibility, and blood metabolites, fifteen Baluchi rams (35.4±2.3 kg body weight) were used in a completely randomized design. Treatments were as follows: 1) common reed, 2) common reed supplemented with 2% urea solution at feeding, and 3) common reed tre...
