Metode Cekaman Luruh Bulu Yang Cocok Untuk Kondisi Di Indonesia

Abstract

The objective of the research is to find out the appropriate and beneficial forced molting program that suitable with the environment and the condition of the farmer in Indonesia. The research used 180 medium type chickens, strain Dekalb Warren, aged 84 weeks old. The research applied 2×2×2 factors and used complete randomized design in (CRD) 5 times replications with 4 chickens for each repeat. The first factor was water supplying and without water supply. The second factor was the duration of no feeding for 10 and 5 days. The third factor was the amount of feed given during recovery period, that was 50% and 25% of the normal consumption. So, the total of the treatment of forced molting program applied were 9 treatments. Data obtained were analysed using analysis of variance (ANOVA), orthogonal comparison test. The result obtained showed that the treatment B (without feeding for the first 10 days, having water supply, day 11 to 30 were feed 25% of normal consumption) could be increasing the average of egg production of old chicken to 68.20%, improving feed convertion, egg quality: Haugh Unit value, yolk percentage, significantly and no differences were obsesrved among treatments versus control for egg weighth, albumen percentage, eggshell thickness. The result was also showed that the Forced Molting Stress Method used in this experiment, would be giving profit of Rp 2,500,000;- per 1,000 chickens if implemented; in the contrary, if the old chickens are allow to keep laying egg without treatment, the farmer would get deficit of Rp 467,000;- per 1,000 chickens
