A comprehensive study on production performance in COBB 430 Y strain of broiler and BV 300 strain layer reared in intensive poultry farm of IVSAH, SOA

Introduction

As per 2021-22, Odisha Economic Survey, Odisha contains 27.4 million birds and ranks 10 th in terms of Chicken population (20 th livestock census, 2019). In India the poultry industry is a well organised sector and is making tremendous growth in the recent years. Factors influencing the growth of poultry sector are modern breeding technologies, advanced managemental practices eco friendly housing methods, advance therapeutics, vaccination, poultry processing units, hatcheries, better feed quantities etc. If a breeder develops a bird of a specific breed by introduction of any economic traits like egg weight, egg size, laying index, FCR, mortality etc is known as strain. They seem to have arisen out of the product of systematic crosses of a few breeds or variety. Breed refers to an established group of birds/animals having the same general shape, weight and some common characteristics. Variety is a sub-division of a breed distinguishable by feather pattern, colour, and shape and comb type. By nature BV 300 strain of layer are considered as good egg producer and not good brooder (Komolafe et al., 1980) [3] . Review of literature related with the study As per the study conducted by Abdullah et al in 2010, stated that feed conversion ratio (FCR) of the broiler belonging to the strain Cobb 500 is superior to any other strains. This is owing to the potential of the strain to consume more amount of feed, better weight gain live weigh t enhanced FCR compared (better efficiency of the bird to convert to meat) to other broiler strain. As per the study conducted by Smith et al., in the year 1988, higher FCR of the bird is due to heavy body weight and requirement of the bird. Higher intake of feed is determined by several factors such as breed or strain, quality of the feed, feed palatability, age, sex, production stage, climatic and other associated environmental conditions. As per the study conducted by Sharma et al., in the year 2019, [6] BV-300 layer breeder has exhibited reproductive as well as productive performance according to their stated standard values under Indian agro-climatic conditions.

Materials and Methods

The present study was carried out under farm condition in LFC, SOADU to study the production performances of spent hen of Cobb 430 Y broiler (1500 heads) and BV 300 layer (2000 heads) for a period of 35 days and 26 weeks, respectively. All recorded and calculated data were statistically analyzed. A sample of individual 150 birds body weight data was recorded manually using 5 kg weighing machine from the 1500 broiler reared in the farm. COBB 430 Y broilers were reared in deep-litter system and BV-300 layers reared in cage system. Feeds and water were given by manual feeder and waterer to broilers and by automating watering and manual feeding in layer birds. The eggs are collected to the egg tray which is fallen from cage and were collected and stored in egg filler. Feeds were provided to the birds twice a day i.e. in the morning as well as in the evening. Clean water was given to the birds throughout the day. Feeds were being provided to the birds as per their nutrient requirement considering their age and egg production (Reddy et al., 1999) [5] . The standard vaccination schedule was maintained for broilers and layers.

Results

Growth Performance

The average weekly body weights of Cobb 430 Y broiler across 5 weeks are shown in Table 1. The average marketed body weight at the end of rearing period (at 5 th week) was 2000 g. Average weight gain at the end of rearing period was 744 g. Average weight gain from 1 st to 5 th week was 97.92g to 744g. This study depicts higher body weight than Vezaguda chicken at the growth stage of 4 th week (Mishra et al., 2023) [4] . Overall average FCR during the rearing period was 1.52. The above table 2 shows the production performance of layer. Average egg laid during the rearing period was 745 and the average hen day egg production was calculated 77%. According to Sharma et al., 2019 [6] average hen day production was calculated 79.51% which was higher than this present study.

Conclusion

This preliminary study provides a baseline data on performance traits of COBB 430 Y and BV 300 layer. We have achieved the average FCR which was 1.52. Average hen day egg production was calculated 77%. This report is a valuable reference for assessing the poultry farm's performance and guiding future improvements and strategic decisions.
