108 milk samples were collected to study the relationship of somatic cell counts (scc) and milk composition with milking methods and udder hygiene from 27 holstein frisian (hf) dairy cows having moderate milk yield in mid-lactation and parity of 2 to 4, at khyber pakhtunkhwa agricultural university peshawar dairy farm. all animals were randomly distributed into three categories on the basis of ...

Background: The mammalian oocyte has the unique feature of supporting fertilization and normal development while being able of reprogramming the nuclei of somatic cells towards pluripotency, and occasionally even totipotency. Whilst oocyte quality is known to decay with somatic ageing, it is not a given that different biological functions decay concurrently. In this study, we tested whether ooc...

somatic embryogenesis is a new approache to plant mass in vitro propagation. this method influences by elements and their components in medium. in order to investigate the effects of different media and it,s role on somatic embryogenesis of carrot, a cbd experiment with four replications (including 12 treatments) was conducted. to do this, carrot petioles (with 1 cm dimension) in induction phas...

in this study, a total of 101,147 monthly test day records of somatic cell count collected from 13,977 first lactation holstein cows (in 183 herds) calved between 2002 and 2006 were used. for the genetic analysis, a random regression test day model was utilized. somatic cell score (scs) was calculated based on natural logarithm of somatic cell count. in the model, fixed effect of contemporary g...

many factors may influence the efficiency of somatic embryogenesis. this capability may be differ with regard to media compositions, genotype, tissue, organ ontology and the stage of differentiation. the effects of five salicylic acid concentrations (0, 25, 50, 75 and 100 mm) on different stages of carrot somatic embryogenesis were studied using petiole and root secondary phloem explants as sta...

Somatic symptoms and somatization process is prevalent in primary care associated with substantial functional impairment healthcare utilization. However, instruments for identifying monitoring somatic are few number not widely used. Adequate psychometric needed to know check symptoms.
