Similar results were reported by Rihani et al. (1993) who performed two
experiments to study the effect of DCP on nutrient digestibility in sheep and Sardi lambs.

In the First experiment, four iso-nitrous and iso-caloric diets having 15, 20, 25 and 30%
DCP in the concentrate were offered to four experimental groups having ten sheep each.

While in second experiment, same diets with same proportions were offered to Sardi lambs

to observe nutrient intake and digestibility. Both experiments lasted for 105 days. At the
end of experiment, they observed that nutrient digestibility was similar among all

treatments in both experiment as non-significant effects of different levels of DCP on

nutrient digestibility in sheep and Sardi lambs were observed.

Martinez and Fernandez (1980) designed a research to check the influence of DCP

on nutrient digestibility in wethers and fattening lambs. The wethers were fed 100 g/kg
alfalfa hay and 900 g/kg of a concentrate mixture. The concentrate contained 0, 150, 300,

450 and 600 g DCP per kg of diet on DM basis. These diets were fed at 46.6 g/kg BW

0.75/day to wethers in metabolic cages. It was observed that there was a linear decrease in
DM and CP digestibility but ADF digestibility tended to increase as the level of DCP in

concentrate was increased in the diet. In another experiment, performed on rams by
Martinez and Fernandez (1980), they observed that digestibility of ADF tended to increase.

However, digestibility of DM, OM and CP were remained unaltered with increasing levels
of DCP up to 600 g/kg.

McCullough and Sisk (1972) evaluated the effects of different levels of DCP on
nutrient digestibility in steers. Two experimental diets containing 15 and 25% DCP of

dietary DM along with ad libitum feeding corn silage was offered to steers. Results showed

non-significant difference among nutrient digestibility between both levels of DCP. Welch
and Smith (1971) performed an experiment to examine the effects of DCP on nutrient

digestibility in dairy heifers. Four dairy heifers having average weight 500 kg were kept in

separate metabolic cages and offered four different levels i.e. 21, 30, 40 and 53% DCP in
concentrate feed along with ad libitum feeding of hay. Experiment lasted for 84 days. At

the end of experiment, results revealed non-significant effects of DCP on nutrient
digestibility in dairy heifers.

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

experimental groups and fed 67.7 and 74.5% DCP in the concentrate ration along with ad
