Comparison of productive performance of frizzle and cross-bred frizzle - naked neck chicken reared under different farm management systems

A study was carried out to analyse the performance of frizzle and cross bred naked-neck frizzle chicken population under various farm management systems. The results of the study revealed that the mean body weights of both sexes of both chicken populations were not significantly different (P<0.05) in all management systems. The age at first laying was significantly early (P>0.05) in frizzle (7.02±0.04months) and naked-neck frizzle (6.93±0.11 months) in extensive system. The mean monthly egg production was significantly higher (P>0.05) for both genotypes under intensive system. The average egg weight (46-47g) and hatchability (76-79%) were significantly higher (P>0.05) in the semi-intensive system. The productive period and life time were significantly longer (P>0.05) under the extensive system for both populations. It was concluded that, both the populations performed well in intensive and semi-intensive management systems with respect to different productive traits

Egg quality parameters of frizzle and naked-neck frizzle chicken genotypes under different farm management systems

A study was carried out to analyse the egg quality parameters of local chicken genotypes such as frizzle chicken and naked-neck frizzle chicken under different farm management systems including extensive, semi intensive and intensive farm management systems. The results of the study revealed that egg quality parameters such as egg fertility, egg hatchability, egg shell weight and egg shell thickness of both chicken population were significantly differed (P0.05) under semi intensive management system while in naked-neck frizzle chicken it was significantly higher (0.65±0.01) in intensive system. From the results, it was concluded, both the population performed well in extensive and intensive management systems for many egg quality traits. However, it is essential to select the cost of production before selecting a suitable management system for both frizzle and naked neck frizzle chickens

Evaluation of the quality traits of hybrid eggs of local chicken genotypes from multi-hybrid crossing technique

Local chicken exist as the valuable genetic resource in Sri Lanka. However, there is lack of breeding and improvement programme for this kind of chicken in the country. In this context, a study was designed to analyze the quality traits of hybrid eggs from cross-bred local chicken. For this study forty local chickens were randomly allocated to four different crossing combinations. Each combination consisted of five hens and a cockerel. The crossing was designed in between village chicken hen and Hy-line white cockerel, village chicken hen and Girirajah cockerel, Naked-neck hen and Hy-line white cockerel and Naked-neck hen and Girirajah cockerel. Hundred hybrid eggs from each crossing were selected for analysis using Statistical Analysis Software (Version 9.0). The results of the study revealed that the egg weight (57.22±2.71g), yolk weight (20.0fttl.54g), yolk albumen ratio (0.74±0.01), specific gravity (1.11 ±0.002) and shape index (79.21±1.42%) were significantly higher (PO.05) in the eggs from Naked-neck X Hy-line white cross. Fertility (79.64±2.29%), shell thickness (0.48± 0.003mm), egg albumen weight (27.1 l±0.94g) and shell thickness (9.92±1.45) were significantly higher (P<0.05) in eggs from Naked-neck X Giriraja. From the study it was concluded that the Hy-line white and Giriraja can be used to improve naked-neck chicken flocks. However, village chicken population should need genetic improvement through different crossing program with other existing exotic breeds in Sri Lanka

Comparison of consumer preference on meat from broiler and village chicken and processed chicken meat products in Batticaloa district of Sri Lanka

The demand for chicken meat is increases in Batticaloa district as the chicken is the major protein source next to fish in this district However, the availability of chicken meat is lower and the prices for meat have also increased. The major sources of chicken meat in the market are village chicken, broiler chicken, cross-bred chicken and processed products. Consumers believe that meat form village chicken is healthier. This poses a particular challenge for the organization of safe marketing chains. Consumer preferences affect the production and marketing systems for poultry products, therefore knowledge and understanding of these preferences is required for the design of appropriate new interventions. In this context, a survey based study was carried out during December, 2009 to May 2010. Two hundred respondents were randomly selected to gather information on the availability of meat and meat products, consumer preference and consumption pattern. The sample was comprised of equal numbers of male and female respondents having education from primary level to graduation in Batticaloa district The results of the study revealed that the availability of broiler meat was significantly higher (P>0.05) in urban areas (66%) while in rural areas the availability of village chicken meat (88%) was significantly higher (P>0.05) than broiler, cross-bred and chicken meat products. Consumers showed significantly higher (P>0.05) preference for village chicken meat (68%) while lowest preference was for processed products (13%). Among processed meat products the consumers showed significantly higher (P>0.05) preference for meat balls (58%). Furthermore, the majority of respondents (73%) liked to purchase meat up to 1kg weekly. Around 76% of the respondents consume meat once a week. Sixty two percent of the consumers were willing consume fish as the substituted for chicken meat and meat products than other substitutes (mutton, beef, pork and crustacean). Farmshed was the major sales point for meat (67%). The respondents were asked to express consumption of meat in case of increased prices and 64% of the respondents had positive response and rest showed negative response to this aspect From the study it was concluded that the consumer preference of chicken meat and meat products showed the positive trend. However, low purchasing power resulted weaker purchasing frequency in rural areas. Government organizations should take efforts for enhance the production and marketing according to the farmers' perception. Results will be much useful in planning the location specific and species based poultry farming and will be beneficial to policy makers also. Key words: Village Chicken, Broiler, Consumer Preference

Scholars Journal of Agriculture and Veterinary Sciences Effects of Feed restriction on the growth performance, organ size and carcass characteristics of Broiler chickens

Abstract: An experiment was conducted with an objective to study the effects of feed restriction on the performance of broiler chicken. Total of 96, Indian River strain, unisex broiler day old chicks were distributed into four experimental units in a complete randomized design. The birds in the control treatment were fed ad libitum throughout the experimental period and the birds in other three treatments were fed restricted by withdrawing the feed for 3 hours (9 a.m. to 12 p.m), 5 hours (9 a.m. to 2 p.m) and 7 hours (9 a.m. to 4 p.m), respectively from day 10 to day 30. Each diet was fed to 24 birds in three replicates. The body weights and feed consumption were recorded weekly and the body weight gains and feed conversion ratio were calculated. Three birds from each replicate were used for the measurement of organ size on day 41. The average weight of the day-old chicks was 50 g. The results revealed that the growth performance and carcass characteristics of broiler chickens were not affected by the feed restriction for 3, 5 and 7 hours. However, significantly higher relative gizzard weights were observed in the birds fed restricted for 3 hours and 5 hours while significantly highest relative liver weight was observed in the birds fed ad libitum
