the low concentrate TMR while 650 g/kg DM corn or DCP was incorporated in high
concentrate level. They indicated that performance of bulls fed high concentrate treatment

along with DCP was lower compared to those bulls, which were fed low concentrate
treatment. However, a non-significant effect was observed on DMI across all treatments.

Rihani et al. (1993) performed two trials to evaluate the effect of DCP on nutrient

intake in sheep and Sardi lambs. In the First trial, four iso-nitrogenous and iso-caloric diets
containing 15, 20, 25 and 30% DCP were fed to four groups of sheep having ten sheep in

each. While in second experiment, same diets with same proportions were offered to Sardi
lambs to observe nutrient intake. Both experiments were 105 days long. At the end of

experiment, they observed that nutrient intake was similar among all treatments in both

experiment as non-significant effects of different levels of DCP on nutrient intake in sheep
and Sardi lambs were observed. Martinez and Fernandez (1980) conducted a study to

determine the effect of DCP on DMI in fattening lambs. Animals were fed 10% Alfalfa hay

and 90% concentrate mixture. The DCP was mixed in concentrate at a level of 0, 15, 30,
45 and 60% in each diet. The results exposed that DMI decreased with an increased level

of DCP in concentrate mixture.

Bhattacharya and Harb (1973) performed an experiment to examine the effect of

DCP on nutrient intake 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 DMI tended to decrease with
increase in the level of DCP. McCullough and Sisk (1972) evaluated the effects of different

levels of DCP on nutrient intake in steers. Two experimental diets having 15 and 25% DCP

of dietary DM along with ad libitum corn silage were offered to steers. Results showed that
there is a non-significant difference on nutrient intake between both levels of DCP. Deaville

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

Suffolk crossbred wethers. Four Suffolk crossbred wethers were equally divided into two
experimental groups. Experimental diets containing 26 and 24% DCP of dietary DM

(concentrate energy source) along with ad libitum grass hay. The results revealed a non-
significant difference on nutrient intake between both treatments.

Welch and Smith (1971) performed an experiment to examine the effects of DCP
on nutrient intake in dairy heifers. Four dairy heifers having average weight 500 kg were

kept in separate metabolic crates and offered four different levels i.e. 21, 30, 40 and 53%
