Abstract/ Executive Summary:

An experiment was conducted for a period of 5 weeks with 240 day-old cobb-500 broiler chicks and were allocated into six dietary treatments with isocaloric and isonitrogenous containing 2975 Kcal ME/kg DM & 21.70% CP and 3077 Kcal ME/kg DM & 20.34% CP both starter and finisher ration respectively. There were 40 chicks per treatment, each treatment had 4 replication having 10 chicks in each. The dietary treatments were T1 (0% triticale + 100% maize), T2 (20% triticale + 80% maize), T3 (40% triticale + 60% maize), T4 (60% triticale + 40% maize), T5 (80% triticale + 20% maize) and T6 (100% triticale + 0% maize). The broilers of all treatment groups were supplied feeds and water ad libitum throughout the experimental period. There were no significant differences (P>0.05) in feed intake, final body weight, total gain, feed conversion efficiency, survivability% but feed cost per kg live broiler production was differed significantly (P<0.01) among dietary treatments at 35 days of age. Therefore, it is clear that triticale is a good alternative cereal for broiler diet without affecting performance and it may safely replace up to 100% of maize but 40% replacement enhance production performance and edible meat yield of broiler and reducing feed cost (Tk. 2.88/kg) per unit of broiler production.

Objectives:

The was conducted to investigate the effect of maize replacement by different level of triticale on the production performance, cost effectiveness and meat yield characteristics of broiler chicken.

Methodology:

A feeding trial was conducted for a period of 5 weeks with 240 day-old Cobb-500 broiler chicks collected from a local hatchery. The initial live weights of the day old chicks were between 42-50g. The chicks were arranged in a completely randomized design with 6 dietary treatments. There were 40 chicks per treatment, each treatment had 4 replication having 10 chicks in each replicate. The dietary treatments were T1 (0% triticale + 100% maize), T2 (20% triticale + 80% maize), T3 (40% triticale + 60% maize), T4 (60% triticale + 40% maize), T5 (80% triticale + 20% maize) and T6 (100% triticale + 0% maize). Lighting was provided for 24 hours for the first 3 weeks and then from 1800 h to 0600 h for the rest of the days. One thermometer and a dry and wet bulb hygrometer were hanged in the experimental room to record temperature and relative humidity. The temperature and humidity percentages were recorded 3 times a day. One feeder and one round drinker were provided in each pen for 10 birds. All mash dry diets were supplied in different feeders for each replication under each treatment to all birds adlibitum, three times a day throughout the experimental period. Water also provided once daily in the morning. The Feeding trial was performed for a period of 35 days. Feed conversion ratio for a particular period was calculated dividing the total feed consumed by the cumulative body weight attained at that period. Management like litter, feeding system and temperature were similar for all treatments. At the end of 5 weeks, 2 broiler from each replication i.e, 8 birds from each treatment was randomly selected considering around same body weight and slaughtered to analyze the morphological and edible meat yield characteristics. Birds were slaughtered following halal method by serving the jugular vein and allowed to bleed completely. Collected and Calculated data were analyzed for analysis of variance using MSTAT-C Computer package program in according to the principles of Completely Randomized Design (CRD). Least Significance Difference (LSD) was done to compare variations between treatments where adjudged by Duncan’s New Multiple Range Test.

Achievement/Findings:

Considering the above facts and findings, it may be concluded that triticale based diet at any proportion in broiler ration had no adverse effect on production performance. Growth performance and meat yield of broilers were better with 40% replacement of maize with triticale in the diet. It is also more profitable due to a reduction of feed cost. So, triticale can easily be used as the replacement of maize in broiler diet on scarcity of maize or its price is higher.
