Public ISBD in Proceedings of the 7th (seventh) National Workshop on Livestock and Fisheries Research, June 22-27, 2007 / Shrestha, B.S.     Title : Cytogenetic Studies in Indigenous Livestock Breeds of Nepal Material Type: printed text Authors: N Gorkhali, Author ; SP Neopane, Author Pagination: 310-316 p. Languages : English (eng) Abstract: Nepal has many domestic livestock population, which are adapted to their particular environments, resistant to many diseases and are suitable to low input management system. If the purity of indigenous stock could be maintained as a reservoir of g<.!nes, they may be of great value for future. Twenty five indigenous livestock breeds were identified so far. Most of the indigenous breeds are characterized in phenotypic level. However, cattle breeds, Lulu and Yak; goat breeds such as Terai and Khari; sheep breeds such as Baruwal, Kage and Bhyanglung and bum1lo breeds such as Lime, Parkote and Gaddi are characterized in chromosomal level. The Lulu cattle had a normal karyotype with 2n = 60, XY or XX. Male had a large submetacentric X chromosome and a small sub-metacentric Y chromosome. In case of buffaloes. Lime and Parkote from Western Development Region have 5 pairs of sub-metacentric autosomes, 19 pairs of acrocentric autosomes and a pair of sex chromosome. In male, X chromosome was the largest acrocentric, whilst the Y chromosome was one of the smallest acrocentric chromosomes. There is breedwise variation in karyotype. In Gaddi buffalo, even though the number of chromosome is same, there is structural variation. In terai goat, metaphasic spread of chromosome has 29 pairs of autosome and a pair of sex chromosome. Among the sex chromosome, X chromosome was larger metacentric while Y chromosome was smaller telocentric type. The karyotype organization ofthree identified sheep ofNepal was found to be the same with chromosomes 2n = 54. If we can characterize each and every descript and non-descript breed in phenotypic and genetic level, we would be able to develop breeding policy for each native commodity and thereby, further action on indigenous breed like promotion and utilization can be done.

Status of Conservation and Utilization of Achhal\11 Cattle / R Mahato ; Amatya, N. ; SP Neopane    

Public ISBD in Proceedings of the 7th (seventh) National Workshop on Livestock and Fisheries Research, June 22-27, 2007 / Shrestha, B.S.     Title : Status of Conservation and Utilization of Achhal\11 Cattle Material Type: printed text Authors: R Mahato, Author ; Amatya, N., Author ; SP Neopane, Author Pagination: 303-306 p. Languages : English (eng) Abstract: Achhami is an indigenous cattle breed located in the far western region ofNepal. This is claimed as the smallest cattle breed in the world. This has several positive attributes such as hardy to many economically important diseases, adaptable to local environment and can produce even in low input system. However the baseline survey of this study shows this cattle is now in endangered stage with population of only 863 in Achham district. Realizing the fact, a study was initiated in 2006 with an objective for its conservation and utilization. This paper emphasizes the phenotypic and productive performance of Achhami cattle. The results showed that adult weight was I 50±0.4 7 kg and body length, heart girth and height girth were 1 00 ems, 116 ems and 86 ems respectively. The average daily milk yield was 1.5±0.47 litres with a lactation length ranges from 180 to 270 days. Achhami cattle mature sexually at 36 months and age at first calving is 46 months. A total of 55 cattle were included for milk recording in Achham district. The results obtained through monitoring for 5 months (Mangsir to Chaitra) showed that Achhami cattle produced 1.5 litre milk per day ranging from 0.5 to 2.4 ± 0.85 litres. The great variation in milk production and tremendous declination in the population ofthis breed needs the serious attention of all the responsible authority.

Study on Production Potentiality of Khari in On-Farm Condition / PK Pokharel ; NL Tamrakar ; SP Neopane    

Public ISBD in Proceedings of the 7th (seventh) National Workshop on Livestock and Fisheries Research, June 22-27, 2007 / Shrestha, B.S.     Title : Study on Production Potentiality of Khari in On-Farm Condition Material Type: printed text Authors: PK Pokharel, Author ; NL Tamrakar, Author ; SP Neopane, Author Pagination: 288-293 p. Languages : English (eng) Abstract: A bench mark study on· on-farm productivity of Khari goat was made at Abu Khairani VDC of Tanahu district of Western Nepal. Semi-structured questionnaire survey, weighing of live goats, and discussion with key informants was carried out in order to collect the status on weight, twinning, goat market and husbandry conditions practiced in the site. Altogether 212 goats of varied colour patterns and parity from 33 households were studied. Twinning of the kids was found to be 72.6 % in against of single 26.4%. Population of Kali (Black) and Khairi (Brown) goats were found more of 32.1 %and 27.8 %respectively than any other available colour pattern. Mean live weight and standard deviation ofthe first parity goat was found to be 21.8± 2.485 kg whereas for the 61 h parity goat the value was 43.4±6.875 kg. The outcome of the study will serve the evaluation of selective breeding program which is being implemented in the site.
