Effect of enzyme supplementation on the metabolisable energy content of solvent-extracted rapeseed and sunflower seed meals for chicken, guinea fowl and quail

1. The nitrogen-corrected apparent metabolisable energy (AMEN) content of solvent-extracted rapeseed and sunflower seed (un-decorticated) meals in relation to species (chicken, guinea fowl and quail) and dietary addition of feed enzymes (0 or 0·5 g/kg diet) was evaluated by a diet replacement method in a 3 × 2 factorial design. 2. The metabolism trial was conducted at two substitution levels (200 and 400 g/kg diet) of each meal with or without supplementation of commercial enzyme preparation in 6 individuals or 6 groups of cockerels, guinea fowls and quails. 3. The experimental diets were fed for a period of 12 d followed by a 3-d collection period during which total feed consumed and droppings output were quantitatively recorded. 4. The AMEN values of rapeseed meal for cockerels, guinea fowls and quails were 8·4, 8·7 and 8·8 MJ/kg, respectively, while the corresponding values for sunflower seed meal were 6·1, 6·1 and 6·2 MJ/kg dry matter, without enzyme supplementation. 5. The AMEN value of rapeseed meal did not improve with enzyme supplementation. However, AMEN values of sunflower seed meal significantly increased with enzyme supplementation, from 6·1 to 6·5 MJ/kg dry matter. 6. Since AMEN values of rapeseed meal and sunflower seed meal were similar in chicken, guinea fowl and quail, values reported for chicken could, therefore, be used for guinea fowl and Japanese quail.

Utilization of Sorghum and Finger Millet With or Without Feed Enzyme in Broiler Chickens

Abstract Elangovan, A.V., Mandal, A.B., Tyagi, Pramod K, Tyagi, Praveen K., Toppo, S. and Johri, T.S. 2004. Utilization of sorghum and finger millet with or without feed enzyme in broiler chickens. J. Appl. Anim. Res., 26: 33–38. A 4x2 factorial experiment of seven weeks duration was conducted on day-old broiler chicks (n=240) to study the efficacy of commercial feed enzyme preparation added @ 50g/quintal in four experimental diets containing either maize, sorghum, finger millet as sole cereal source or a combination of maize, sorghum, finger millet and pearl millet in equal proportions on performance, nutrient utilization, carcass traits and feed cost of production. The body weight gain and feed efficiency were significantly lower (P<0.01) in finger millet based diet, which were improved (P<0.01) upon enzyme addition. However, addition of enzyme in diets based on other cereals did not improve the performance of broilers. The enzyme addition significantly (P<0.05) improved the dry matter and gross energy metabolizability with higher nitrogen retention from diet containing finger millet. The carcass traits remained unaltered (P>0.05) by various dietary treatments. Feed cost of broiler production was higher (P<0.05) in finger millet based diet. It is concluded that diet containing finger millet, a poor quality grain, can be improved by adding commercial feed enzyme preparation.

Effect of Feeding Rice Gluten Meal (RGM) on Haematological, Serum Biochemical and Carcass Traits in Broilers

Poultry industry is the fastest growing sector in Indian agriculture. Feed is the major constituent in the poultry production accounts for 65-75% of total recurring expenditure. Feed costs are primarily driven by the cost of protein sources. Substitution of expensive protein sources with lower cost ingredients would potentially reduce the cost of the feed. Soybean meal (SBM) is the major protein source used in poultry diet. Instability in its production, indiscriminate exports and higher demand has resulted in its shortage for the poultry industry leading to its higher price. Substitution of SBM at reasonable price will lead to economic broiler production.

Effect of rice gluten meal as protein source in the diet of broiler chicken: Immunity, gut microbial count, haematology and serum bio-chemical parameters

Rice gluten meal (RGM), a by-product of wet-milling of rice, is relatively a new feedstuff having brownish coloured coarse powdery texture. An Investigation has been planned to explore the feeding value of RGM in the diet of broiler chicken. A 6 week study was conducted on 240 CARI BRO VISHAL chicks of same hatch with uniform weight. The birds were randomly assigned to six isocaloric and isonitrogenous dietary treatments including control group, containing RGM at 0, 5, 7.5, 10, 12.5 and 15% levels. Each group comprised of 40 birds. The overall results of the present study on immunity, gut microbial count, haematology and serum biochemical parameters did not show any significant (P>0.05) difference among different dietary treatments and control group during 0–6 weeks of feeding period. The study envisaged that rice gluten meal can be safely incorporated upto15% level as a substitute of soybean meal without any adverse effects on immunity, gut microbial count, haematology and serum bio-chemical parameters in broiler chicken.
