Comparative study on morphological and morphometric features of village chicken in Sri Lanka

Abstract

ABSTRACT:A study was conducted in two selected sites (Anuradhapura and Puttlam districts)

Phenotypic characterization of the indigenous chickens <i>(Gallus gallus)</i> in the northwest of Algeria

“…Males had significantly darker combs than females. This finding agrees with results of Guni et al (2013) in Tanzania and Liyanage et al (2015) in Sri Lanka. As the intensity of the red colouration is an indication of the quality of sperm in the case of male birds (Navara et al, 2012), our results indicate that there is probably good fertility in the birds investigated.…”

“…In females chickens (Table 8), WS alone accounted for 97.2 % of the variation in BW and was nearly not improved by the addition of BrW, TL, TC, CH, and BL in the regression equation. Liyanage et al (2015), using a regression analysis, showed significant relationships of body weight with every linear trait, while chest circumference and shank length were the best predictors of live weight in vil- Ajayi et al (2012) reported that the highest contributor to the variation in body weight in normal feathered Nigerian indigenous chickens was body length, which again highlights the importance of determining specific equations for local populations, which differ for a lot of characteristics, including genetic background and environmental factors of production. According to the results of PCA, using PC1 as a single predictor already explained 81.2 and 80 % of the total variability in body weight in males and females, respectively.…”

Factors Influencing the Morphological Characteristics of Village Chickens’ Genetic Resources in the Abu-Dhabi Emirate, UAE

“…Village chickens (VCs) are those kept under traditional raising system and used for multiple purposes with variable morphological characteristics [1] [2] [3]. In many regions of the world, VCs are kept for several goals which include local consumption, extra income, pest control and manure production [4] [5] [6] [7].…”

“…In general, even if local breeds have low production rate, they are more adapted to their environment and they may reserve an essential and special genes or traits that could meet the changeable preferences of consumers, alteration of production systems, and resistance to newly developing diseases [13]. Consequently, VCs are gene reservoirs for genetic future studies, improvement and conservation [3] [6].…”

Production systems of village chickens in the Abu-Dhabi Emirate, UAE

“…Many meanings are found from the term village chickens (VC) in literature, though it can be defined as those chickens kept under traditional system of raising for multiple purposes with no identified description (FAO, 2012;Aklilu et al, 2013;Liyanage et al, 2015). Raising VC has several purposes in many regions of the world which include; local consumption, extra income, pest control and manure production (Muchadeyi et al, 2004;Mtileni et al, 2009).…”
