Page 15 - Effects of dried citrus pulp on nutrient intake, nitrogen balance and growth performance in Lohi lambs

Similarly, Alkire (2003) conducted a study to evaluate the effects of feeding citrus
pulp supplements on the performance of growing beef cattle. They used fifty Angus x

Brahman crossbred steers and heifers for the experimental purposes. They fed them
individually. These calves were fed Bahia grass hay as a basal diet at ad libitum intake

along with concentrate. The concentrate consisted of corn and citrus pulp with increasing

levels of un-degradable intake protein. The experiment continued for 84 days. It was
observed that calves supplemented with corn grains ate 0.7 kg more hay compared to those

fed citrus pulp.

Miron et al. (2002) carried out an experiment to observe the effect of DCP on

nutrient intake in dairy cows. Ten cows were equally divided into two experimental groups.

Animals of group 1 offered TMR having 10% DCP and 20% corn while animals of other
group were offered TMR having 21% DCP and 9% corn. Both TMRs also contained 6.5%

soya bean meal, 14% extruded full fat soya bean, 28% corn silage, 19.5% legume haylage,

minerals and vitamins. These results showed that nutrient intake was higher in cows offered
TMR having 10% DCP than those offered TMR having 21% DCP.

Bueno et al. (2002) carried out an experiment to evaluate the effect of DCP in
replacement of corn grain (concentrate energy source) and its effect on nutrient intake in

Saanen kids. Sixteen kids were taken into metabolic cages. Corn was replaced by DCP at
0, 23, 46 and 66.5% as concentrate energy source and fed to animals along with ad libitum

chopped grass hay. Results revealed that nutrient intake was higher in those Saanen kids
fed diet having 46% DCP. However, above this level, there was a reduction in nutrient

intake. Similarly, O’Mara et al. (1999) conducted a comparative trial to evaluate the effects

of DCP on nutrient intake using sheep and cattle. Four sheep (7-9 months age) and four
cattle (1.5 years age) were offered 77.7% DCP of dietary DM as concentrate energy source

along with 16% hay and 0.63% soya bean meal. Results showed nutrients intake

coefficients of DCP were similar between sheep and cattle in significant manner.

A better DMI of DCP as concentrate energy source in goats was observed when fed

along with Alfalfa hay in 50:50 proportions on DM basis. An increased DM and OM intake
was found in animals who were fed dried citrus pulp. While the supplementation has no

significant effect on ADF NDF and CP intake (Madrid et al., 1996; Madrid et al., 1997).
Scerra et al. (1994) also reported significant effect of DCP on nutrient intake in rams.

Fegeros et al. (1995) carried out a study to examine the effect of DCP on nutrient intake in
