Page 19 - Effects of dried citrus pulp on nutrient intake, nitrogen balance and growth performance in Lohi lambs

of DCP in concentrate feed along with ad libitum feeding of hay. Experiment was 84 days
long. At the end of experiment, results revealed that there is a non-significant effect of DCP

on nutrient intake in dairy heifers. Loggins et al. (1968) performed an experiment to study
the effect of DCP on nutrient intake in lambs. There were seventy-six lambs equally divided

into two experimental groups and fed 67.7 and 74.5% DCP in the concentrate rations along

with ad libitum feeding of Bermuda grass hay to the lambs. Experiment was 90 days long.
The results revealed a non-significant effect of DCP on nutrient intake in lambs fed

different levels of DCP, as results were similar among all the treatments.

Aregheore (2000) conducted two research trial to evaluate the effect of DCP as a

by-product on DM intake of small ruminants. Four by-product feeds (BPF) from groundnut

shells, maize cobs, cassava peels and citrus pulp + peel waste were used to make treatment
diets. Goat (12 heads) and sheep (16 heads) of 16-18 months having average weight of

12.96 and 14.05 kg respectively were selected. They were divided into three and four

groups respectively. At the end of the experiment, it was observed that there was a better
intake of diet containing cassava peels. Diet containing citrus pulp was observed to have

second best DM intake.

Belibasakis and Tsirgogianni (1996) conducted a research to investigate the effect

of DCP on nutrient intake. They selected twenty Friesian cows and divided them into two
groups of ten cows. Two experimental diets were designed. First diet having 20% DCP

while, the other one having 15% beet pulp. They offered the feed twice a day to ensure ad
libitum feeding. At the end of the experiment, they found a non-significant effect on DM,

CP and ME intake.

Broderick et al. (2002) executed a research to investigate the effect of DCP on
nutrient intake in cows. They selected 48 lactating Holstein cows having 596 kg body

weight. Cows were divided into two groups and stalled individually. All diets contained
50% alfalfa silage 10% ryegrass silage, 28% NDF. In addition, concentrates were added to

six diets HMEC (high moisture ear corn), CSC (cracked shelled corn), HCP (50:50 mixture

of high moisture ear corn and DCP) and their combination with ESBM (expeller soybean
meal). At the end of the experiment, they observed a higher intake with CSC and its

combination with ESBM as compared to HMEC, HCP and their combinations with ESBM.
DM intake calculated by Bampidis and Robinson (2006) is given in Table 2.2.
