Abstract/ Executive Summary:

The study was conducted to observe and compare the phenotypic characteristics of ISA brown and Hisex brown commercial layer strains. A total of 200 birds were examined out of 36000 in a commercial layer farms at Chandonysh upazila (sub-district) of Chittagong district, Bangladesh during the period of July to December, 2013. Observable difference was found in several phenotypic characteristics like plumage, beak, shank, egg, comb color and comb type between ISA brown and Hisex brown. In ISA brown shank length (cm), egg weight (gm) and body weight (gm) was 3.32±0.01, 59.44±0.47 and 1846.60±11.18 respectively where in case of Hisex brown it was 3.11±0.00, 55.82±0.45 and 1769.10±33.90. Significant (P<0.05) difference was found in shank length (cm), egg weight (gm) and body weight (gm). In ISA brown beak length and age at first lay was 2.02±0.01 and 141±0.51 respectively, On the other hand for Hisex brown, it was 2.02 ± 0.01 and 141 ± 0.58. There was no Significant (P>0.05) difference between the strains in respect of shank length, egg weight and body weight. Some innate characteristics of studied strains differentiate them and any improvement program of commercial layer strains should be incorporate production objectives and trait performance of the society.

Commodity: Poultry

Objectives:

The present study was conducted to compare phenotypic characters between Isa brown and Hisex brown.

Methodology:

The study was conducted on commercial layer farm at Chandonysh upazila, Bangladesh. This area is located in the south-eastern region of Bangladesh at 22.2438 latitude and 92.0126 longitude. It is a part of the Chittagong Division. The duration of the study was six months from July to December, 2013. The present study was conducted on 36000 layer strains of ISA brown and Hisex brown reared in a commercial poultry farm. A total of 200 birds were examined. They reared Hisex and ISA brown in ten shed and in five shed birds are reared in cage system and in another five sheds’ birds are reared in deep litter system. Among ten shed, five sheds used for ISA brown and five sheds for Hisex brown. They have separate shed for rearing day old chick from brooding to pullet. In brooding shed, they provided feed adlibitum which contains 21% CP and 2900 kcal ME/kg up to 8 weeks and 16% CP and 2650 kcal ME/kg up to 18 weeks and in layer 17% CP and 2750 kcal ME/kg up to 72 weeks. The birds were vaccinated against Mareks, Newcastle, Fowl cholera, chicken pox and Gumboro diseases. The necessary data of related parameters were collected from record book of the poultry farm. Twenty birds were randomly selected from each shed and the following data were collected during the period of study by a previously structured questionnaire; (One hundred Hisex and one hundred ISA brown). Data were collected on the following parameters: Beak length (cm) and shank length (cm) were determined by using measuring tape, where egg weight (gm) and body weight (gm) were determined by using digital balance. Other non-measurable data were collected by eye estimation like plumage color, beak color, shank color, egg color, and comb color and comb type, The age at first lay was calculated as duration of days between day old chicks (DOC) to start of egg laying. The housing system was open sided for layer and closed house for brooding chick. In case brooding each chick guard contains 1200 chicks where space was 720 square feet, contains electric brooder or gas brooder. It is increased according to age and up to 16 weeks of age. For the prevention of diseases fresh and clean water were supplied to bird and each 75 birds need one round drinker and after 3 days later used nipple drinker (one nipple drinker for 8 to 10 birds) with round drinker. The experimental farm supplied feed to Day old chick (DOC) on especial flat feeder for 2 days. They provide linear feeder @ 2.5 cm/bird. The starter rations start after 24 hours of arrival and contained CP 19 to 20%, ME 2950/kg, lysine 1.07, and methionine 0.43 to 0.54%. Adlibitum feeding was allowed for 3 weeks. Then weighing which compared with guide line. The obtained information was imported, stored and coded accordingly using Microsoft Excel, 2007 for analysis. Then the data were imported in SPSS v16 statistical software.

Achievement/Findings:

Population of commercial layer strain in Bangladesh is increasing. Chicken is only species that is expected to be found in village that serves as a source of income and nutrition. Therefore emphasis should be given from stakeholders (policy makers, research and development bodies) to increase chicken population. Bangladesh has diversified agro-ecologies that may be attributing for the presence of diversified phenotypic appearance of commercial layer strain. Most communities from different parts of a country have been attaching their social believes and life with such morphological characteristics of commercial layer chicken. This may create influences on the market values of poultry. Thus any breeding and improved production program of the commercial layer should therefore, incorporate the production objectives and trait performances of the society. By improving the approaches and traditional management of commercial layer, better performance always been achieved from these birds. Hence, these huge gene pool should be protected from genetic erosion and apply for improvement through scientific selection together along with technologies of genomics.
