Evaluation of the association of SLC11A1 gene polymorphism with incidence of paratuberculosis in goats.

Paratuberculosis is one of the chronic granulomatous enteritis that predominantly affects ruminants world wide, caused by Mycobacterium avium ssp. paratuberculosis (MAP). In ruminants, microsatellite polymorphisms of the 3' untranslated region (3'UTR) of the solute carrier family 11 member A1 (SLC11A1) gene were associated with resistance to intracellular pathogen infections.

cDNA cloning, structural analysis, SNP detection and tissue expression profile of the IGF1 gene in Malabari and Attappady Black goats of India.

Insulin-like growth factor 1 (IGF1) plays an important role in growth, reproduction, foetal development and cell proliferation. The present study was conducted to clone and sequence the full-length coding sequence of the caprine IGF1 gene from Attappady Black and Malabari breeds, two indigenous goat breeds of south India, to analyse its structure, and to ascertain the relative abundance of IGF1 mRNA in different tissues. The caprine IGF1 cDNA (GenBank accession nos: KJ549851 and KJ549852) contained a 465-bp open reading frame encoding IGF1 protein with 154 amino acid residues.

Returns and determinants of technical efficiency in small-scale Malabari goat production units in Kerala, India.

A stochastic frontier production function was employed to measure technical efficiency and its determinants in smallholder Malabari goat production units in Kerala, India. Data were obtained from 100 goat farmers in northern Kerala, selected using multistage random sampling. The parameters of the stochastic frontier production function were estimated using the maximum likelihood method.
