الملخص الإنجليزي

The main object of this study was to assess the productive and physiological responses of broiler chickens to dietary pigeon pea (Cajanus cajan) leaf meal “PPLM”.

The chemical composition of PPLM was determined.

200 day-old, unsexed Ross (303) broiler chicks were used as experimental birds.

They were distributed to 5 groups, each of which subdivided into 10 replicates (4 bird / replicate) following the completely randomized design.

5, experimental diets were formulated to be isocaloric and isonitrogenous (NRC, 1994) with graded levels of PPLM (0.0%, 2.5%, 5.0%, 7.5% and 10.0 %), at the expense of alfalfa meal which was included at 10.0 % in the control diet.

Feed and water were provided ad labium.

Experimental period lasted for 7 weeks.

During the first 10 days all birds fed on the control for adaptation.

During the rest of the experimental period, birds received their respective experimental diets till the end of experiment (day 49).

Feed intake and body weight were recorded on weekly basis.

At the end of the experiment 10 birds from each group were selected randomly and slaughtered.

The dressing out percent, weights of organs and length of intestine and ceca were determined.

Also serum cholesterol was measured.

Proximate analysis results showed that PPLM contains 97.73 % dry matter, 16.59 % crude protein, 1.32 % crude fat, 38.90 % crude fiber, 9.34 % ash, 30.58 % nitrogen free extract and 6.8 (Mj \ kg) metabolizable energy (ME).

Rresults revealed that the total feed intake in all PPLM treatments was higher than the control (0.0 %) PPLM, but the difference was significant only between level (2.5 %-5.0 %) PPLM and control (P<0.05).

Total body weight gain was improved at 5.0 % PPLM compared to the control while the other levels were inferior than it, the difference was significant (P<0.05) between control and both of level (7.5 %-10.0 %) PPLM.

Feed conversion ratio (FCR) results showed that all birds fed PPLM were lagging after control.

No significant difference detected between control and 5.0 % PPLM.

In conclusion the study showed that the pigeon pea (Cajanus cajan) shows great promise as source of leaf protein for poultry in the Sudan and recommends intensive interdisciplinary study of its agronomic biochemical and nutritional characteristics.
