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

Age at first eggs were longer in the crossbred groups and the delay was mostly caused by the dominant genes from the exotic parents.

Abstract:

Bovine babesiosis is also known as cattle tick fever, red water disease or piroplasmosis in cattle. Bovine babesiosis is one of the major haemoprotozoal disease of cattle in India. The losses caused by this disease to the livestock industry is highly devastating. In India the estimated annual losses due to Bovine babesiosis is found to be about ≈57.2Million USD. This disease is of great economic importance in India and have always challenged the livability of crossbreed and exotic cattle.

Abstract Hemorrhagic septicemia is a fatal disease of cattle and buffalo all over the world, including Pakistan, and it causes heavy economic losses every year. The poor farmers cannot bear this loss in the form of less milk production and heavy expenditures on the animal treatment. An enriched alum-precipitated vaccine with reduced dose was prepared and standardized, and safety testing of the enriched vaccine was performed in Swiss albino mice as well as in natural hosts. In this experiment, a total of 36 cattle both male and female, of different age groups ranging from 4 months to 4 years, w

India possesses world’s largest bovine population with 193.46 million cattle, out of which 51.36 million cattle are exotic/crossbred and 142.11 million cattle are indigenous/non-descript (BAHS,2022), which is about 12.67% of the world cattle population. India ranks first in the world, contributing 23% of global milk production. The total milk production was 221.06 million tonnes and per capita availability was 444 grams per day in 2022 (BAHS, 2022).

South African indigenous sheep breeds include Namaqua Afrikaner, Zulu, BaPedi, and Damara sheep. These breeds are the most preferred breeds by rural farmers in South Africa due to their adaptability, low feed, and veterinary requirements. However, since they are characterized by small body sizes, farmers tend to crossbreed them with exotic breeds.
