Abstract

Our work consists in characterizing the breeding of local chikens "Gallus Gallus domesticus" in the wilaya of Guelma (East Algeria), as also the phenotypic and morpho-biometric characterization of this species.

To achieve this, a survey was carried out in the field between November 2016 and August 2017, the following points were analysed: the socio-economic situation of the breeders, the farming method based on the history of the livestock, with phenotypic and morpho-biometric characterisation of 231 chickens from this region.

According to the surveys, women are the main managers of livestock farms to meet certain living needs; the population average is 11 chickens per farmer and the creation of livestock farms by farmers over an average period of 2 years; 27.3% of the farmers surveyed buy domestic village chickens and 41.8% of the market, the results also show that 92.7% of farmers indicate that almost all farms are in open breeding mode with the purchase of adult birds; 5.5% of farmers involve a closed mode and 61.8% the reproduction mode with known parents, 38.2% unknown parents, so over half the farmers are aware of at least one parent.

The results obtained for 231 hens sampled show a very different source of characteristics: the most frequent feather colours are walleye with 11.53%, brown with 11.37% and wheat with 11.17%, red with 9.33% and white with 8.44%, the other colours are: mille-fleurs, herminé, black, copper black, partridge, salmon, stone, grey and cuckoo are at lower frequencies ranging from 2.52% to 7%., The dominant feather distribution on the body is normal with 77.72%, the skin color is distributed as follows: white 39.8%, pink 34.64%, yellow with a variability of 21.59%, but rarely a pigmented skin with 4.02%,

The body measurements under consideration (body weight, tarsal length and diameter, barbel length and crest height) confirm sexual dimorphism with higher values in males than females,
