Page 34 - Effects of dried citrus pulp on nutrient intake, nitrogen balance and growth performance in Lohi lambs

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 there was a non-significant effect of different
levels of DCP on nitrogen metabolism.

Williams et al. (1987) planned two experiments to evaluate the effect of DCP on

nitrogen metabolism in Friesian calves. They selected 40 Friesian calves in first
experiment. Diets were formulated with different ratios of barley to pulp. Diets comprised

100:0, 67:33, 33:67 and 0:100 ratio of barley to pulp. At end of the experiment they found
that there was increased level of nitrogen retention in animals fed DCP up to 33% in the

diet

Chen et al. (1981) performed an experiment to check effects of DCP in replacement
of corn on nitrogen metabolism in lambs. Three types of concentrates were formed at

different levels including 0, 10 and 20% DCP in lamb feed. Results declared that there was
an increased intake in control diet. They also reported that there was a less retention of

nitrogen in diets containing DCP.

Bhattacharya and Harb (1973) performed an experiment to examine the effect of
DCP on nitrogen balance in Awassi lambs. Citrus pulp was dried at 90˚C. The DCP was

mixed in concentrate at the level of 20, 40 and 60% (on DM basis). The diets were fed to
lambs in 4x4 Latin square design. Results revealed that nitrogen increased at the level of

20% of DCP while a decreased retention of nitrogen was observed in lambs fed 60% DCP

in diet.

Oni et al. (2008) conducted a study on the effect of DCP in replacement of brewers

dried grains on the nitrogen metabolism in dwarf goats. Sixteen goats were equally divided
into four groups. Control group had 88.5% brewers dried grains whereas, in other three

experimental groups, it was replaced with 25, 50 and 75% DCP. Enterolobium cyclocarpum

was used as a basal feed. Molasses, vitamin mineral premix, salt and urea were also used
in all diets. Results indicated that there was a decreased intake of nitrogen when the goats

are fed more than 25% DCP in their diets. An increased outgo of nitrogen was also noted
when the goats were fed more than 25% of DCP in their diets. The nitrogen balance tended

to decrease when the level of DCP in goat diets was increased than 25%.
