Rabbit feeding on cow manure supplemented diets

Radwan M.S.

Twenty-eight New Zealand White rabbits (1560 + 23 g) were divided into four groups of seven. Treatments were control, 10, 20 or 30 per cent of dried cow manure (DCM). Diets were nearly isonitrogenous and isocaloric. Approximate chemical analysis of DCM was 14.3 per cent crude protein; 2.8 per cent ether extract; 30.0 per cent crude fibre; 32.0 per cent NFE and 20.4 per cent crude ash. The total digestible nutrients (TDN) values were 80.0, 68.3, 61.5 and 54.5 per cent; those for metabolizable energy (ME) were 3.29, 2.78, 1.70 and 1.33 MCal/kg food. The digestibility coefficient values for dry matter were 84.8, 75.3, 63.2, 53.2 and 53.8 per cent; and those for organic matter were 84.6, 75.2, 64.5 and 57.5 per cent respectively. Supplementation of DCM resulted in low body gains, feed intake and poor conversion ratios, compared to the control diet. The 30 per cent DCM rabbit group had a significant difference (P less than 0.01). Digestion of most of the nutrients were greatly affected by DCM additions (P less than 0.05). The poor performance of incorporated diets could be related to palatability of diets, dietary fibre levels and the type of that fibre. Using DCM in rabbit diets up to 20 per cent gave adequate growth, while 30 per cent DCM diet failed to support performance as compared to the control diet and more trials are necessary to evaluate DCM with breeding stock.
