Abstract:
Assessment of village chicken egg quality parameters were conducted in two agro-ecology and eight rural kebeles, in Chelliya district. A total of 120 households were participated in the survey. Eggs were collected from 15 households for determination of egg quality parameters and two eggs were collected each from indigenous, cross breed and exotic, hence ten eggs were collected from each breed. Total of 240 eggs were used for this experiments. The objectives this study was to assess some quality parameters of eggs produced under scavenging production system.

Abstract:
To improve the reproductive performance; several scholars conducted research in different parts of Ethiopia on indigenous, crosses and exotic chickens. However, there were inconsistencies among the various studies. This review was, therefore, conducted to assess the reproductive characteristics of indigenous, exotic and their crosses. Under scavenging system, the indigenous chickens are characterized by less clutch size (2.7-4.2 per year), good hatchability rate (59.6-93.2%), higher mortality rates (25.3-61.15), and reach sexual maturity at advanced age (19.6-26.8 weeks for male; 19.7-34.05 we

The objective of this review paper was to review dorper sheep cross breeding with indigenous sheep breed in Ethiopia. The paper reviewed and discussed the history of dorper breed introduction, research and development efforts in crossbreeding and their performance under on-station and on-farm management. Formal survey on farmers perception on Dorper cross sheep indicated that the crossbred dorper sheep have non selective feed behavior and excellent in meat production under farmer`s management.

Abstract:
There is still limited information on the genomic structure and genetic diversity of African pigs. Genetic diversity studies can contribute significantly to the genetic improvement and conservation of African pigs. This study presents a genetic diversity analysis and population structure of pig breeds in Ghana, with a focus on the Ashanti Dwarf pig (ADP), an indigenous pig breed of Ghana. A total of 167 pigs sampled in Ghana and populations consisting of Ashanti Dwarf pigs (n = 106), exotics (mostly European pigs) (n = 11), crosses (between indigenous and exotic breeds) (n = 44), and unknown b

Abstract:
To compare the reproductive and productive performance of exotic crossbreds and indigenous Terai cattle under farmers' management condition, a household survey was carried out in 218 households of Bardiya, Nepal. Total of 262 cows [Jersey cross (n=107), Holstein cross (n=24) and indigenous Terai cattle (n=131)] were considered to determine the production and reproduction parameters. The age at first calving in months was the lowest in Jersey crossbred (27.8±1.8) followed by Holstein cross (29.5±4.0) and Terai cattle (45.7±3) (P<0.05).

Faecal samples (39,896) from native, crossbred and exotic sheep managed under farm condition in both arid and semi-arid agro-climate of Rajasthan were evaluated for incidence and intensity of strongyle infection (predominated by Haemonchus contortus). In semi-arid region, parasitological profile showed relatively the lowest susceptibility of Garole and its crosses followed by Malpura, Chokla, Kheri and the highest susceptibility in crossbreds.

Abstract:
Beta-casein (CSN2) is one of the important bovine milk proteins synthesized by β-casein gene. The aim of this study was to investigate the A1 and A2 allelic variants of CSN2 gene in Holstein-Friesian and Local (HF×L) crossbred cattle of Bangladesh. Allele specific polymerase chain reaction (AS-PCR) was carried out for genotyping of allelic variants. A total of 390 blood samples of HF×L crossbred cattle was included from govt., military and private dairy farms. Six different crossbred genotypes were identified in the studied population as 50%HF×50%L, 62.5%HF×37.5%L, 68.75%HF×31.25%L, 75%HF×25%L

Bovine anaplasmosis is one of the most important tick borne diseases of ruminants worldwide causing significant economic losses in the livestock industries due to the high morbidity and mortality in susceptible cattle herds. Bovine anaplasmosis, caused by Anaplasma marginale, is an infectious but non-contagious disease. The mode of transmission of bovine anaplasmosis includes mechanical (blood contaminated fomites (needles, ear tagging, dehorning and castration equipment), biological (tick bites) and transplacental (mother to fetus).

Abstract:
In Mesolithic and Neolithic southern Scandinavia, Sus is often the animal found most commonly on archaeological sites, and it undoubtedly formed a major part of the meat diet throughout the prehistoric period. Unfortunately, it is difficult to ascertain whether this meat comes from wild boar (Sus scrofa) or domestic pigs (Sus scrofa f. domestica), as archaeologists have only the bones to go on when seeking to determine the status of the animals they study. This contribution will examine bones from a series of sites, most in Denmark but some also in Sweden. Three main areas will be considered.

Ethiopia is located in tropical region and livestock production represents a major national resource and forms an integral part of the Agricultural production system and livelihood of the society. Dairy farming being one of the agricultural production in Ethiopia, is practiced mainly as an extensive type of management system, which involves smallholder farmers in rural areas and semi-intensive and intensive managements in per urban and urban areas. Despite a large number of milking cows, there is low milk production because of many factors, including low genetic potential of indigenous breeds,
