The study was conducted in midland and lowland agro-ecological zone of North western zone of Tigray, Ethiopia. Two districts were selected purposively based on their potential exotic chicken breed production. Out of the total chicken producers in the study area 264 farmers, 132 from each of the two districts were selected randomly using systematic random sampling methods. It was conducted in cross sectional survey data from 264 respondents in 2016. Its aim was to assess the contribution of producing exotic chicken to dietary diversity of the rural households with 24 hours recall method. The study examines the study area is characterized in a low dietary diversity mainly defined by starchy staples (grains, condiments, oil or fats) at the expense of protein sources (meat, fish, fruits, vegetables, eggs). The result also indicates that there is a higher probability of the exotic chicken producers groups to move from a medium dietary diversity status to a high dietary diversity status as compared with indigenous chicken producers. Based on the study result, there is possibility to improve dietary diversity and income of the households through introduction and dissemination of exotic chicken breeds to rural households. Hence, governmental and non-governmental organizations should help in intervention of exotic chicken breed to the farm households by giving different incentives.

Japanese indigenous chickens have a long breeding history, possibly beginning 2000 years ago. Genetic characterization of Japanese indigenous chickens has been performed using mitochondrial D-loop region and microsatellite DNA markers. Their phylogenetic relationships with chickens worldwide and genetic variation within breeds have not yet been examined. In this study, the genetic characteristics of 38 Japanese indigenous chicken breeds were assessed by phylogenetic analyses of mitochondrial D-loop sequences compared with those of indigenous chicken breeds overseas. To evaluate the genetic relationships among Japanese indigenous chicken breeds, a STRUCTURE analysis was conducted using 27 microsatellite DNA markers. D-loop sequences of Japanese indigenous chickens were classified into five major haplogroups, A–E, among 15 haplogroups found in chickens worldwide. The haplogroup composition suggested that Japanese indigenous chickens originated mainly from China, with some originating from Southeast Asia. The STRUCTURE analyses revealed that Japanese indigenous chickens are genetically differentiated from chickens overseas; Japanese indigenous chicken breeds possess distinctive genetic characteristics, and Jidori breeds, which have been reared in various regions of Japan for a long time, are genetically close to each other. These results provide new insights into the history of chickens around Asia in addition to novel genetic data for the conservation of Japanese indigenous chickens.

Abstract. Functional polymorphisms in pattern recognition receptors (PRRs) modulate innate immunity and play a crucial role in resistance or susceptibility to diseases. The present study was carried out to explore polymorphic patterns in the coding sequences of PRR genes TLR3, TLR1LA (TLRs), MDA5, LGP2 (RLRs) and NOD1 (NLR) in chicken breeds of India, namely Ghagus (GH), Nicobari (NB) and the exotic White Leghorn (WLH) breed. Out of 209 SNPs observed in five genes among three breeds, 117 were synonymous (Syn) and 92 were non-synonymous (NS) SNPs. In TLR genes the highest polymorphism was observed in NB (16, 28) compared to GH (14, 16) and WLH (13, 19) breeds. In the MDA5 gene the highest polymorphism was observed in GH (12) compared to NB (eight) and WLH (four) breeds. However, an almost similar level of polymorphism was observed in the LGP2 gene among the three breeds. In the NOD1 gene, the highest polymorphism was observed in NB (27), followed by WLH (11) and GH (10) breeds. The overall highest number of SNPs was observed in NB (90), followed by GH (62) and the WLH (57) breed. With regard to variation in polymorphism among different classes of PRRs, the study revealed the highest polymorphism in TLRs compared to NOD1 and the RLR class of PRRs. Further, the domain locations of various Syn and NS SNPs in each PRR among the three breeds were identified. In silico analysis of NS SNPs revealed that most of them had a neutral effect on protein function. However, two each in TLR1LA and LGP2 and one in the MDA5 gene were predicted to be deleterious to protein function. The present study unravelled extensive polymorphism in the coding sequences of the TLR and NLR class of PRR genes, and the polymorphism was higher in indigenous chicken breeds.
