Table 1. Proximate composition <strong>of</strong> experimental ration and poultry litter (%DM)<br />

Proximate principle Experimental ration (%) Poultry litter (%)<br />

Dry matter 91.25 93.45<br />

Organic matter 80.00 63.21<br />

Crude protein 12.18 15.70<br />

Ether extract 1.87 0.87<br />

Crude fibre 30.17 15.08<br />

Total ash 20.00 36.78<br />

Acid insoluble ash 6.19 12.39<br />

Nitrogen free extract 35.78 31.57<br />

Calcium 0.89 4.57<br />

Phosphorous 0.76 3.7<br />

on various factors like dry matter, season, climatic<br />

condition and type <strong>of</strong> feed (Taneja, 1969; Mehrothra<br />

and Mullick, 1960).<br />

<strong>The</strong>re was no significant difference in<br />

digestibility co-efficient <strong>of</strong> Dry matter, Organic matter,<br />

(Table 2). Similar findings were reported by<br />

(Mallikarjuna, 1989), in sheep and goats fed rations<br />

containing cotton straw, maize cobs for dry matter.<br />

A non-significant difference in digestibilities for Crude<br />

Protein was observed in sheep and goats. Similar<br />

results were reported by (Murthy et al., 1996) when<br />

fed poultry litter and poultry droppings in the pelleted<br />

ration. <strong>The</strong> lower digestibility <strong>of</strong> Crude Protein in the<br />

present experiment may be due to incorporation <strong>of</strong><br />

cotton seed hulls at 40 percent level. <strong>The</strong> cotton seed<br />

hulls contained about 31 percent lint, mostly made<br />

<strong>of</strong> cellulose and about 14.3 percent lignin. It is quite<br />

likely that proteins in the cotton seed hulls are located<br />

in the structural component <strong>of</strong> cell. Structural protein<br />

(Maynard et al., 1981) which may not be available<br />

for the microbes to attack due to high lignin content.<br />

Further the fineness <strong>of</strong> cotton seed hulls during<br />

processing might have also contributed to lower<br />

digestibility due to faster rate <strong>of</strong> passage through the<br />

digestive tract (Keys and Smith., 1984). <strong>The</strong>re was<br />

no significant difference in ether extract and crude<br />

fibre digestibility in the two species <strong>of</strong> sheep and<br />

goats (Table 2). <strong>The</strong> findings are in agreement with<br />

those <strong>of</strong> (Sreedhar et al., 1993).<br />

<strong>The</strong> non-significant difference in Nitrogen free<br />

extract digestibility between sheep and goats<br />

observed in the present study concur with the results<br />

<strong>of</strong> (Murthy et al., 1996) who also reported nonsignificant<br />

difference in Nitrogen free extract<br />

digestibility between sheep and goats fed poultry<br />

litter/poultry droppings based pelleted ration. All<br />

experimental animals were in positive N, Ca, and P<br />

balances indicating that the experimental feed<br />

supplied these nutrients in required quantities to both<br />

species. Sheep retained significantly (P>0.01) higher<br />

N, Ca and P than goats (Table 2). This could be<br />

attributed to higher Dry matter intake in sheep. <strong>The</strong><br />

ration met Digestible crude protein (DCP) and Total<br />

digestible nutrients (TDN) requirements as<br />

recommended by ICAR (1985). <strong>The</strong> results <strong>of</strong> this<br />

study indicate that complete feed containing poultry<br />

litter up to 35 percent level could be utilized for feeding<br />

<strong>of</strong> small ruminants. <strong>The</strong> complete ration formulated<br />

in this study met the nutritive requirement <strong>of</strong> sheep<br />

and goats. Further it was observed that poultry litter<br />

could be used up to 35 percent level in complete<br />

feeds <strong>of</strong> small ruminant rations as an un- conventional<br />

protein source without any adverse effect.<br />
