520	3		_aAn investigation was carried out to evaluate the effect of supplementation of sodium sulphate in White Leghorn layer diets devoid of animal protein sources. White Leghorn 'Ft strain pullets of 20 weeks of age were wing banded and randomly distributed to five different dietary treatment groups, each with eight replicates of four birds each. The dietary treatment consisted of control ration (T1) prepared using unsalted dried fish as animal protein source, all vegetable protein diet with the addition of 300 g DL-methionine (T2), all vegetable protein diet with the addition of anhydrous sodium sulphate at the levels of 200 g (T3), 300 g (T4) and 400 g (Ts) in every 100 kg of diet. All the rations were formulated as per BIS (1992) specification of nutrients for layer chicken. Soyabean cake, groundnut cake and gingelly oil cake were used as protein sources in vegetable protein diet. Body weight at 20 and 48 weeks of age, age at sexual maturity, egg production, feed intake, feed efficiency, egg weight, livability and cost-benefit analysis were the major criteria considered for the evaluation. The data were recorded for seven, 28 day periods. There was significant difference in body weight at 48 weeks of age (P<O. 05). Body weight of birds fed with standard layer ration (T1) and birds fed with 0.4 per cent sodium sulphate were significantly (P<0.05) higher than those birds fed with 0.3 per cent sodium supplemented diet. But body weight of birds fed with standard layer ration (T1) was comparable with body weight of birds fed with vegetable protein diet having 0.4 per cent sodium sulphate (Ts). Similar trend was followed in egg weight also, with significantly higher egg weight in treatment group fed with 0.4 per cent sodium sulphate (Ts). Egg weight of birds fed with standard layer ration (T1) was comparable with T, (P<O. 01). But parameters like age at sexual maturity, hen-day and hen-housed egg production and feed efficiency were not affected by the supplementation of Sodium Sulphate. Feed intake showed significant (P<O.Ol) difference between dietary treatments. The group fed with 0.3 per cent methionine (T2) had significantly lower feed intake in comparison with 0.2 per cent (T3) and 0.3 per cent sodium sulphate (T4) supplemented group. Feed intake of birds fed with control diet (T1) was statistically comparable with all treatment groups except those birds fed with vegetable protein diet with 0.4 per cent sodium sulphate (Ts). Mortality pattern showed no difference among the five dietary treatments tested. All vegetable protein ration prepared with the addition of either methionine or sodium sulphate had higher price when compared with standard layer ration. Based on this study it was surmised that sodium sulphate supplementation did not have any deleterious effect on production performance of White Leghorn layers. So methionine or sodium sulphate can be effectively utilized in formulation of all vegetable layer ration when scarcity of fish occurs.
