Abstract

The objective of the study was to evaluate whether mannanase supplementation in the low protein diet fed to laying hens from 31 to 45 weeks of age would improve egg production and quality. The experiment was designed into completely randomized designed with 2 treatments and 20 replicates. Two hundred and thirty six  31-week old ISA brown hens were distributed at random to individual cage. Two experimental diets containing 15% protein without (0%) or with mannanase supplementation (0,05% [72,5 MU/kg product Elanco, Animal Health IN, USA] ) were assigned to cages, so each treatment had 20 replicates with 5- 6 birds per treatment. Feed intake, egg production (hen day and egg mass), egg weight, and feed conversion ratio (FCR) were recorded every week in the period of 31-35 weeks and 42 to 45 weeks of age. On Week 34 and 45, eggs were collected for egg quality analysis (albumen height, haugh unit, yolk color, shell thickness, shell strength and shell weight). Data were subjected to one way of ANOVA (with 20 replicates per treatment). The results showed that mannanase supplementation had had no effects on performance parameters (feed intake, egg production, egg weidht, and FCR) measured at 31 to 35 weeks of age, but had significant effect (P <0,05) on daily feed intake, and FCR on 42 to 45 weeks of age. With regard to egg quality, only egg shell weight was improved by mannanase supplementation. In conclusion, dietary supplementation to low protein diet could improve feed conversion and egg shell quality.

Abstract

ABSTRACT Ration in pellet form could increased feed efficiency level compared to mesh in poultry. The objective of the research was to  evaluate Morinda citrifolia leaves in ducks ration on the pellet physical quality and rancidity level after storing. The treatments diet contained 18 % of crude protein and 3000 kkal kg-1 metabolizable energy.  Pelleting diet process used simple wood pellet without steam, pellet knife and coller. The experiment was factorial using completely randomized design. Factor A was the percentage of mengkudu leaves (0, 2.5, 5 and 7.5%). Factor B was the period of storage (0, 3 and 6 weeks). The data were analyzed by using analysis of varian (ANOVA) and Duncan Multiple Range test. The variables were moisture content, water activity, density, compact bulk density, bulk density, pellet durability, pellet durability index, angle of repose, particle size, peroxide value, and fat content. The result showed that supplementation of Morinda citrifolia leaf and storage period significantly (P<0.05) affected the water activity and moisture content. Supplementation 7.5% of Morinda citrifolia leaves reduced (P<0.05) pellet density. The average pellet density in 0% Morinda citrifolia and 7.5% Morinda citrifolia were 1.27 g mL-1 and 1.22 g mL-1 respectively. Storing ducks pellet up to 6 weeks decreased physical pellet quality as indicated by increasing moisture content, water activity and the peroxide value. Keywords : Morinda citrifolia, pellet diet, peroxide value, storage
