|Abstract:||An investigation was carried out to assess the effect of dried spleen as a growth promotant in kid rations. Twenty four female Kalahari kids with an average body weight of 8.5 kg were distributed randomly and as uniformly as possible into four groups (groups I, II, III and IV) of six animals each, with regard to age and weight. The four dietary treatments A, B, C and D were alloted to the kids in the groups I, II, III and IV respectively, ration A with a concentrate mixture containing 16 per cent crude protein supplemented with dried buffalo spleen at the rate of 0.1 per cent, ration B forming the control diet at 16 per cent protein level without incorporation of spleen, ration C with a concentrate mixture containing 12 per cent crude protein supplemented with dried buffalo spleen at the rate of 0.1 per cent, ration D forming the control diet at 12 per cent protein level. Jack leaves formed the sole source of roughage to the animals. The experimental duration was 120 days. 11 The results indicated that incorporation of dried spleen in the ration enhanced the growth performance of animals, especially in animals maintained on low level of protein , as evidenced by the cumulative and average daily weight gain registered in that descending order being 7.52 kg and 62.64 g, 7.4 kg and 61.67 g, 6.88 kg and 57.36 g and 5.00 kg and 41.67 g for the animals maintained on rations C, A, B and D respectively. The efficiency of feed and protein utilisation also exhibited the same trend. It was also noticed that, a cost of production per kilogram gain of Rs. 32.58 and 26.14 were registered for animals maintained on spleen incorporated rations (rations A and C) as against Rs. 35.08 and 38.63 respectively for the animals maintained on corresponding control groups (ration B and D) indicating a better cost efficiency in spleen incorporated groups, especially in animals maintained on low level of crude protein in the ration. The haematological studies reveal that R.B.C., W.B.C., haemoglobin, plasma protein, plasma calcium, phosphorus and magnesium were within the normal range prescribed for the species. The animals maintained on ration C showed a significant increase (P<0.01) in plasma calcium level when compared to that of the control. Digestibility studies reveal no significant difference in digestibility of dry matter and nitrogen Ill free extract between the four groups. Animals maintained on the spleen incorporated rations (groups I and III) showed better digestibility (P<0.01) of crude protein and ether extract than the respective control groups (groups II and IV). Incorporation of dried spleen could not bringforth any influence on fibre digestion. The results of the balance experiment showed better retention of nitrogen, calcium, phosphorus and magnesium in the animals maintained on spleen incorporated diets. The higher retention of these parameters could be substantiated by the comparatively lower faecal and urinary excretion of these, in animals maintained on spleen incorporated rations (rations A and C). An over all assessment of the results, indicated that incorporation of dried buffalo spleen in the ration of goats, at the rate of 0.1 per cent, certainly augment the nutrient utilisation by increasing the digestibility and retention, and can be recommended as a harmless natural growth promotant with economic benefit.|
