Sex specific genetic and environmental trends for birth weight in indigenous Nguni conservation cattle herd of Zimbabwe

Best linear unbiased predictors (BLUP) of breeding values for additive direct and additive maternal genetic effects were estimated from pedigree birth weight (BWT) records 4272 in indigenous Nguni cattle born between 1988 and 1997. Data was partitioned according to sex and breeding values for direct additive and maternal additive were estimated using a univariate animal model. Estimates of sex specific genetic trends...

Testicular biometry and its relationship with body weight and semen output of black Bengal bucks in Bangladesh

Biometrical study of testes were done in twelve black Bengal bucks (Capra hircus) of three different age groups, 0.5 to 1.0 years (group A), 1.5 to 2.0 years (group B) and 2.5 to 3.0 years (group C) to find out the age depended changes in the biometry of testes and their relationship with semen quality. Before slaughtering the bucks, the semen quality of the bucks of three different age groups was evaluated in terms of...

Purification and characterizations of NAD dependent isocritrate dehydrogenase from human kidney mitochondria

NAD-IDH (Nicotinamide adenine dinucleotide socitric dehydrogenase) has been purified in 1216-fold with a total recovery of 7.5% from the mitochondria of human kidney by using a combination of affinity chromatography with the anion-exchange matrix that allowed obtaining a preparation of high purity. The shape of the peak from Sephacryl S-100 and the results from SDS-PAGE confirm that the enzyme is a tetramer with...
