were two treatments, control and citrus pulp; the control treatment had 91.3, 8.3 and 0.42
% DM of lucerne, lupins and phosphate, respectively whereas fresh citrus pulp treatment

had 57.7, 9.5, 0.48 and 32.3% DM of lucerne, lupins, phosphate and fresh citrus pulp,
respectively. Results revealed that nutrient intake was lower in animals fed fresh citrus pulp

based diet than control treatment. Macedo et al. (2007) carried out a trial to evaluate the

effect of fresh citrus pulp as a replacement of sorghum silage on nutrient intake in male
crossbred sheep. The average body weight of all male sheep was 28.3 kg (±2.41). In

comparison to control diet, sorghum silage was substituted by fresh citrus pulp at 25, 50

and 75% levels. Results revealed a better nutrient intake at all levels of fresh citrus pulp
than sorghum silage.

Similarly, Cooke et al. (2007) performed an experiment to observe the effect of
DCP on nutrient intake in Brahman British cows. There were twenty-four cows equally

divided into two experimental groups and offered two different TMRs having molasses and

DCP along with ad libitum feeding of forage hay. At the end of experiment, they found that
cows fed DCP based TMR had less nutrient intake than those supplemented molasses based

TMR. Contrary to these, Villarreal et al. (2006) examined the effect of DCP on nutrient
intake in steers. Experiment was performed on three steers (average body weight 324±16

kg) who were randomly offered three different levels of DCP (0, 1.25 and 2.5 kg DCP/
animal/day) in a 3x3 Latin square design along with ad libitum feeding of a basal diet (star

grass) to the steers. They found that nutrient intake reduced when the level of DCP was

increased. Reduction in nutrient intake with increasing levels of DCP might be due to
provision of low fiber and low protein energy concentrate.

Taniguchi et al. (1999) performed an experiment to study the effects of DCP on
nutrient intake in steers. Steers were offered four TMRs in 4x4 latin square design. First

TMR had 40% Italian ryegrass, 48% rolled barley grains and 12% soya bean meal. Second

TMR had 38% Italian ryegrass, 18% rolled barley grains, 30% DCP and 14% soya bean
meal. Third TMR had 27% Italian ryegrass, 32% rolled barley grains, 30% beet pulp and

11% soya bean meal and 4th TMR had 14% Italian ryegrass, 51% rolled barley grains, 30%
soya bean hulls and 15% soya bean meal. Results revealed a non-significant effect of DCP

on DMI in steers. Henrique et al. (1998) performed a study to examine the effect of
substituting corn grain with DCP on nutrient intake in young bulls. These bulls were offered

diets having corn silage along with concentrate at levels of 200 or 800 kg/tones DM in

TMR. The 70 g/kg DM of the concentrate was used by incorporating corn grain or DCP in
