BACKGROUND The domestic goat is one of the important livestock species of India. In the present study we assess genetic diversity of Indian goats using 17 microsatellite markers. Breeds were sampled from their natural habitat, covering different agroclimatic zones. RESULTS The mean number of alleles per locus (NA) ranged from 8.1 in Barbari to 9.7 in(More)
The Indian subcontinent contains 20 well-characterized goat breeds, which vary in their genetic potential for the production of milk, meat, and fibre; disease resistance; heat tolerance; and fecundity. Indian goats make up 20% of the world's goat population, but there has been no extensive study of these economically important animals. Therefore, we have(More)
Variance components and genetic parameters were estimated for post-weaning (i.e., at 6, 9, and 12 months of age) body measurements in Muzaffarnagari sheep maintained at the Central Institute for Research on Goats, Makhdoom, Mathura, India over a period of 29 years (1976 through 2004). Records of 2,965 lambs descended from 162 rams and 1,213 ewes were used(More)
AIM The objective of this study was to investigate the effect of genetic and non-genetic factors and estimate the genetic parameter for gestation length (GL) of Jersey crossbred cattle. MATERIALS AND METHODS The data included the 986 parturition records on Jersey crossbred cattle maintained at the Eastern Regional Station of ICAR-National Dairy Research(More)
The birth of live heterosexual quadruplets (three females and one male) in cattle (Bos indicus) is a very rare event and hence this study was conducted to observe the chromosome constitution of the dam and the heterosexual quadruplets. The cytogenetic study revealed sex chromosome chimerism (2n = 60, XX/XY) and preponderance of female cells (XX) in the(More)
The simplest non-destructive method of potassium determination is to co-relate the fixed abundance of naturally occurring (40)K with the total amount of potassium. Earlier this relationship was applied by measuring the β(-) activity of (40)K in a sample by Geiger counter. However, merely this simple linear relationship has been applied through gamma(More)
AIM Dynamics of faecal egg count (FEC) in Haemonchus spp. infected goats of two Indian goat breeds, Jamunapari and Sirohi, in natural conditions was studied and effects of genetic and non-genetic factors were determined. MATERIALS AND METHODS A total of 1399 faecal samples of goats of Jamunapari and Sirohi breeds, maintained at CIRG, Makhdoom, Mathura,(More)
