Abstract: Indigenous ducks in Kerala are reared extensively by foraging in post harvest paddy fields, traditionally. Large number of ducklings is being produced in Alappuzha district and the grown up ducks are distributed among duck growers in other districts. The layer ducks are being reared in flocks of 500 to 5000 and the minimum flock size is 500 layers. The present study was carried by distributing 10 layer ducks each in 75 households in three districts. The results indicated that the duck housed egg number was 59.15, 78.24 and 73.88 eggs per duck in Thrissur, Malappuram and Ernakulam districts respectively with corresponding duck housed per cent (DHP) production of 32.32, 42.75 and 40.37 up to 44 weeks of age during the period from June to November. A significant variation in egg production was observed due to variations in feeding system. The feasibility of rearing of ducks under backyard system of rearing was proved successful in Kerala.

Abstract: An experiment was conducted to evaluate the performance of caged layer ducks (144) fed high fibre diets supplemented with Polyzyme, a cocktail enzyme preparation. The birds were divided into four groups of 36 ducks each having 3 replicates of 12 ducks each. A basal diet having 18% CP, 2650 kcal ME/kg and 8% CF was prepared and fed to T1. Paddy was added to basal diet to make a CF of 12% and fed to T2. Groups T3 and T4 were fed with diet T2 supplemented with enzyme at 0.1 and 0.2% levels respectively. The birds in the group T3 recorded superior performance with respect to duck housed number, duck housed per cent, feed efficiency, egg weight, egg mass and livability.

Abstract: A field trial was carried out in 1000 layer ducks to evaluate supplementary feeding of Jowar (Sorghum) grains and economics over egg production during the lean season. The monsoon rain period is the lean season in Kerala since the paddy fields are submerged. Four farmers with flocks size 250 each was chosen at four locations. Jowar (Sorghum) was supplemented @ 150g per duck per day for three months. The mean daily egg production from a flock of 250 ducks averaged 104.87, 154.06, 90.84 and 147.75 eggs with farmers I, II, III and IV respectively. The corresponding duck housed percent production was 41.95, 61.62, 36.34 and 59.10 per cent. The egg production recorded with farmer II and IV were significantly higher than those recorded with farmer I and III (P<0.05). The supplementary feeding was found to be beneficial to maintain egg production. The farmers could earn a net profit of Rs. 50 per day from a flock of 250 ducks against ‘Zero’ returns with traditional method of providing only maintenance feed during lean season.

Abstract: Hatching eggs from white Leghorn chicken maintained at AICRP on poultry, Mannuthy were first examined visually and then candled to remove the defective eggs unfit for hatching. A total of 540 defective eggs were then categorized into 10 different groups as described by USDA (2000) and Coutts and Wilson (2007) as misshapen, pimply shelled (having calcareous deposits on the surface), ridge shelled, body checked (sealed cracks), mottled (porous), hairline checked, misplaced and tremulous air celled and eggs having blood spots. The eggs with dented or star or impact cracks were grouped a severe cracks. These defective eggs along with 200 hatching eggs, which are free from any such defect were used a s control and were set in setter operated at 37.4 ± 0.2ºc dry bulb and 28.9± 0.2ºc wet bulb temperatures. He fertility of eggs having blood spots was significantly (P<0.05) low (75.00 ±7.37vs 95.50 ± 1.47 in control) while other defects did not have any influence on fertility. The eggs with blood spots also had significantly (P<0.05) higher (50.00 ± 12.36) incidence of EED, while all other treatment groups were statistically similar to control (5.76 ± 1.69). The incidence of DG was significantly (P<0.05) more in eggs having severe cracks (33.33 ± 9.83) misplaced air cell (47.83 ± 10.65) and tremulous air cell (35.71 ± 13.29) in contrast to control (4.71 ± 1.54).

Abstract: The effect of dietary crude fibre levels (8 and 12 %) and enzyme supplementation on production performance of indigenous layer ducks from 21-56 weeks of age was evaluated. Two hundred female ducks were divided in to five treatment groups each having four replicates of ten ducks each. The group T1 was fed with a diet containing 18.03% crude protein (CP), 2552Kcal/kg metabolizable energy (ME) and 8.02 % crude fibre (CF). In the other four groups T2, T3, T4 and T5 the dietary crude fibre level increased to 11.86% and supplemented with Polyzyme at 0, 0.06, 0.12 and 0.18 % levels, respectively. The body weight of ducks at 40 weeks of age was not significantly affected either by crude fibre levels or enzyme supplementation in the diet. The body weight of layer ducks at 52 weeks of age was significantly (P<0.05) higher in 0.18 per cent enzyme supplemented group (T5) than the group fed with 8 % CF diet (T1). The cumulative Duck housed egg number from 21 to 56 weeks of age in all the 12 % CF diet groups were significantly (P<0.05) higher than that of 8 % CF group (T1) with highest value in 0.06 % enzyme supplemented group (T3). The mean egg weight from 21 to 56 weeks of age was significantly (P<0.05) higher in all enzyme supplemented groups than that of 8 % CF group (T1). The mean daily feed consumption per duck (21 to 56 weeks) was significantly (P<0.05) higher in all high fibre diet groups than 8% CF group. Feed conversion ratio per dozen eggs was superior in 0.06% enzyme group but the difference was statistically non-significant. Feed conversion ratio per kilograms of eggs was also non-significant between the groups. The results indicated that 12% crude fibre could be included advantageously in the diet of indigenous layer ducks. Supplementation of 0.06% polyzyme in 12 % fibre diet improved the production performance of indigenous layer ducks.
