digestibility might be due to same proportions of pectin, uranic acid, glucose and fructose
in all diets due to which similar nutrient digestibility was observed in all treatments.

Taniguchi et al. (1999) carried out an experiment to study the effects of DCP on

nutrient digestibility 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 fourth TMR had 14% Italian ryegrass, 51% rolled barley
grains, 30% soya bean hulls and 15% soya bean meal. Results revealed that CP digestibility

in DCP treatment was lower whereas NDF digestibility was similar to other treatments in

steers.

Sparkes et al. (2010) examined the effect of replacing lucerne hay with fresh citrus

pulp on nutrient digestibility in ewes. Two treatments were used. Control treatment had
91.3, 8.3 and 0.42 % DM of lucerne, lupins and phosphate, respectively whereas the fresh

citrus pulp treatment had 57.7, 9.5, 0.48 and 32.3% DM of lucerne, lupins, phosphate and

fresh citrus pulp, respectively. They reported that animals fed fresh citrus pulp showed
higher nutrient digestibility than control diet. Similarly, Gholizadeh and Naserian (2010)

checked the effect of dried citrus pulp replacing barley grains on nutrient digestibility in
Saanen kids. Dried citrus pulp was supplemented at 7, 14, and 70% of the energy

concentrate and was fed to twelve female Saanen kids. Non-significant effects of dried
citrus pulp were observed on apparent digestibility of DM, CP, NDF and ADF.

Deaville et al. (1994) executed an experiment to evaluate the effect of DCP on

nutrient digestibility in Suffolk crossbred wethers. Four Suffolk crossbred wethers were
equally divided into two experimental groups. The experimental diets consisted of 26 and

24% DCP of dietary DM (concentrate energy source) along with ad libitum grass hay. The
results revealed non-significant differences on nutrient digestibility between both

treatments. _ENREF_24Fegeros et al. (1995) performed an experiment to check the effect

of dried citrus pulp on nutrient digestibility in ewes. The ewes were fed 7.5, 15, 22.5, 30,
37.5 and 45% DCP of dietary DM along with hay. Results showed that crude fiber

digestibility was higher whereas in ewes who were fed 30% DCP lower of dietary DM than
those offered 7.5, 15, 22.5, 37.5 and 45% DCP whereas, apparent digestibility of DM and

CP were un affected at all levels of DCP in ewes.
