Reproductive Disorders and Seroprevalence of Brucellosis in Yak / Aryal, S.R. in Nepal Agriculture Research Journal, Vol. 8 (2007)
[article]
Title : Reproductive Disorders and Seroprevalence of Brucellosis in Yak Material Type: printed text Authors: Aryal, S.R., Author ; Krishna P. Paudel, Author Publication Date: 2007 Article on page: 130-132 p General note: Research note Languages : English (eng) Keywords: BRUCELLA ABORTUS, BRUCELLOSIS, REPRODUCTIVE DISORDERS,SEROPREVALENCE, YAK Abstract: A study on reproductive disorders among yaks in Mustang and Solukhumbu districts and
seroprevalence of brucellosis among yaks in Mustang and Myagdi districts was conducted.
Eleven farmers having 383 female and 72 male yaks in Mustang and 129 female and 27
male yaks in Solukhumbu districts were taken by purposive random sampling for the study
on reproductive disorders. Likewise Sixty- seven serum samples were also collected from
adult female yaks having history of abortion and retained placenta, and from male yaks used
for breeding purpose from Mustang and Myagdi districts. An average of 12.63% of female
yaks aborted, 7.26% had had retention of placenta and 6.6% repeat breeders in Mustang
district. Similarly, 6.3% had abortion, 2.09% retained placenta and 6.5% repeat breeders in
Solukhumbu district. However, all the 67 serum samples examined were found negative to
the Brucella abortus antibody on ELISA test suggesting that the yak population was free
from brucellosis in these areas. Thus abortion and retention of placenta in Yak in Mustang
district may not be due to brucellosis. A detail study should be done to find the specific
cause of abortion and repeat breeding to recommend preventive and control measures.Link for e-copy: http://elibrary.narc.gov.np/?r=39

Title : Genetic and Non-Genetic Factors Affecting Reproductive Traits of Pakhribas Pig in Nepal Material Type: printed text Authors: Shriram P. Neupane, Author Publication Date: 2007 Article on page: 77-81 p Languages : English (eng) Keywords: Genetic and non-genetic parameters, hills of Nepal, Pakhribaspig, reproductive traits Abstract: Pakhribas pig is a black colour pig and is highly preferred by the people in the Eastern hills
of Nepal. This breed was developed in Nepal by three-way crossing of exotic breeds
(Saddle back, Fayuen and Tamworth) at Agricultural Research Station (ARS), Pakhribas,
the then Pakhribas Agricultural Centre (PAC). The data of 348 pigs, born over a period of
fifteen years (1990 to 2004) were used to study the effect of non-genetic factors on
reproductive traits and estimate their genetic parameters. The findings revealed that the
overall gestation length and farrowing intervals were 113.7 ± 0.12 days and 182.5 ± 2.2
days, respectively. Season of birth and parity of dams were not important sources of
variation for reproductive traits, where as year affected these traits significantly.
Heritability estimates of gestation length was low (0.02 ± 0.094), but heritability for
farrowing interval was moderate (0.14 ± 0.147) suggesting selection based on farrowing
interval would bring the improvement in the trait.Link for e-copy: http://elibrary.narc.gov.np/?r=31
