Abstract/ Executive Summary:

A total of ninety-six Shaver 579 pullets were fed on isocaloric and isonitrogenous diet with vitamin-mineral premixes, Supramixes Layer, Acimix Super-L and Adivit-L and without premix (control) in the age duration from 25 to 40 weeks to evaluate the efficacy of different commercial premixes. Daily feed intake and body weight gain of the pullets did not differ significantly (P>0.05). Hen day egg production of different treatments differed significantly (P<0.01). Higher and statistically similar egg production was obtained in Supramix layer (75.4%) and Acimix Super-L (74.12%) treatment. The lowest (62.5%) and statistically similar (65.99%) egg production occurred in control and Adivit-L treatment respectively. Egg weight of the treatments differed significantly (P<0.01). The highest (57.15g) and statistically similar (56.57g) egg weight was observed in supramix Layer and Acimix Super-L group respectively. The highest egg mass output of Supramix Layer (42.98) differed significantly (P<0.01) from the control (33.98). Significant (P<0.01) difference was observed in the FCR value of Supramix Layer (2.68) and control (3.43) group. Broken egg percent of the treatments differed significantly (P<0.01). High broken egg (4.11%) was observed in control group. No significant (P>0.05) differences were observed in livability. The observation of the results showed that use of commercial vitamin-mineral premix to supplement the diet of caged laying pullets is inevitable to maintain desirable production level. But the efficacy of all commercial premixes was not equal. The quality of marketed premixes is not uniform which is revealed in terms of performance test in the study.

Objectives:

To study the economic feasibility of using vitamin-mineral premix in laying diet and to recommend a suitable vitamin-mineral premix to the poultry producers from those available in the market.

Methodology:

The research was conducted for 16 weeks duration at Bangladesh Agricultural University Poultry Farm, Mymensingh with 96 Shaver 579 pullets to evaluate the efficacy of a few vitamin-mineral premixes available in Bangladesh on the performance of laying birds. Four treatments were compared for this experiment. Each treatment had 3 replications. Required feed ingredients for making diet for experimental birds were supplied by the Poultry Farm of BAU. Vitamin-mineral premixes were purchased from the local market of Mymensingh district town. The premixes Supramix layer of Jayson Agrovet, Acimix super-L of ACI and Adivit-L of FNF company were considered for experimental purpose. The experimental house was first made clean and disinfected by using disinfectant to avoid microbial contamination. The feeder, waterer and feed container also cleaned and disinfected. Then birds were transferred gently in clean laying cages and randomly to avoid biasness. The caged birds were allowed two weeks to adjust before feeding test diets. A diet without vitamin-mineral premix was given to the experimental birds of all treatments for a week to observe the actual effect of premix in subsequent experimental period. Locally available feed ingredients supplied by BAU Poultry Farm formulated diets. Here, it is notable that the amount of all ingredients for four diets of the treatments was same. The requirements of ME, CP, critical and limiting amino acids, Ca and P content were satisfied according to the recommendation of Shaver Breeding company, Canada. The samples of supplied feed ingredients were made for chemical analysis. Samples of feed ingredients (wheat, fish meal, soybean meal, rice polish, bone meal, sesame oil cake and oyster shell) were stored in airtight screw capped bottles for subsequent chemical analysis. Samples of feed ingredients were analyzed to determine dry matter (DM), crude protein (CP), crude fibre (CF), ether extract (EE), nitrogen free extract (NFE) and total ash in the Poultry Science Laboratory following the standard procedures of proximate analysis. Analytical procedures to determine crude protein (CP), crude fibre (CF), total ash, and ether extract (EE) content of all the feed ingredients were performed following A.O.A.C. The experimental birds were exposed to similar care and management through out the experimental period. At the same time, strict care was maintained to protect pullets from unhealthy condition. The day length was less than 16 hours during the experimental period. So a provision was made by using 60-watt electric bulb to meet up 16 hours light per day for maximum laying performance according to the recommendation of Shaver 579 Breeder Company. Feeder and waterer were cleaned and disinfected regularly to avoid microbial contamination. The floor of the experimental house was cleaned regularly. The experimental diets were prepared weekly and stored in tin container. Feed and water was offered twice daily, once in the morning and again in the afternoon in such a way that feeders and waterers were not kept empty. The eggs laid by the experimental birds were collected two times daily i.e., in the morning at 11 o'clock and in the afternoon at 3.30 PM. Treatment wise body weight of birds were taken at the beginning of the experiment and then fortnightly to monitor the change in body weight during the experimental period. Weekly feed consumption for each treatment was recorded by subtracting the left over of the feed from the total amount of feed supplied to the respective treatment. The number of eggs laid by each treatment was recorded daily and weighed just after collection in replication wise. In case of broken or abnormal eggs, weights were considered as average of the eggs laid by the same replication of the treatment on the same day. Replication wise the number of broken eggs were recorded daily. Any kind of shell broken of eggs was recorded. The collected data on laying performance and egg quality characteristics were analyzed using a package program Stat Graphics. Data for different variables were subjected to analysis of variance in Completely Randomized Design (CRD). Multiple comparisons were made where ANOVA showed significant differences. Duncan's Multiple Range Test was used to compare the pair of mean values.

Achievement/Findings:

From the results of the experiment it is concluded that use of commercial vitamin-mineral premix to supplement the layer diet is inevitable for obtaining desirable production performance. And extra care must be taken for caged laying pullets during summer season in terms of supplementation of vitamins and minerals to the diet to reduce the broken egg percent. And the efficacy of all marketed commercial vitamin-mineral premixes was not equal rather the quality of some premixes is questionable. So, it will be good enough if government make strict rules and regulations in the light of experience of developed country during importation and marketing of nutritional and medicinal products of poultry.
