2. History of AI
• 1332 AD : Arab Chief in Horse ( but not scientific)
• 1777 AD : in reptiles, by Spallanzani
• 1780 AD : Spallanzani, Produce puppies from beagle dog
• 1900 AD : Extensive study of AI in Russia, than after in Japan

4. • An Artificial Insemination Project was started at Tripureswor, Kathmandu in
B.S. 2025/26 (1969/70), and AI program received further momentum after
establishment of Liquid Nitrogen (LN2) Plant in the year 2037/38
(1980/81).The Project was renamed as Animal Breeding Division (ABD) and
was shifted to Khumaltar in the year 2041/42 (1985/86). The ABD initiated
breeding activities in cattle, buffalo, sheep, goat, pig, and poultry with main
emphasis on AI in cattle and buffalos. In 2046, when ABD became a part of
Nepal Agriculture Research and Services Center (NARSC), the Department of
Livestock Services (DLS) started AI program naming it Artificial Insemination
Services. The Artificial Insemination Services was renamed Animal Breeding
and Artificial Insemination Program in 2048/49 (1991/92) and was made a
part of the Department of Agriculture Development (DoAD). With
restructuring of the Agricultural Ministry and re-establishment of DLS in
2052/53 (1995/96) and the program was named as Animal Breeding and
Artificial Insemination Section. The section was relocated to Lampatan,
Pokhara in the year 2058/59 BS (2001/02 AD) with same name as Animal
Breeding and Artificial Insemination Section and renamed National Livestock
Breeding Center in 2061/62 (2004/05).
19. Quality of Semen required for AI
• Post-thaw Motility 40 %
• Post-thaw Viability of Semen 10 % after 3rd hour
• Live Sperms % (55% at NLBO)
• Abnormal Sperms Up to 20 %
• Sperm Concentration/dose (million) 15-30
