The aim of this study was to determine whether processed karanj (Pongamia glabra) oil seed cake can be used as a supplement to partially replace soybean meal (SBM). Male lambs (n = 24) of uniform body weight (12.88 +/- 0.15 kg) were equally allotted at random to a SBM-based control (CON) and three test concentrate mixtures, containing detoxified solvent extracted karanj cake (SKC) using three processing methods: water washing (WW), 2.5% lime (LM) and 0.4% binder (BN) treatment. The processed SKC replaced 50% nitrogen of SBM of CON. The respective concentrate mixtures were fed along with ad libitum chaffed oat (Avena sativa) straw for 196 days. Dry matter intake was significantly (p < 0.01) lower on WW, LM and BN. Apparent digestibility coefficient of nutrients was comparable, except for total carbohydrates, which was significantly (p < 0.01) lower in LM and BN. Total gain, average daily gain and feed: gain ratio was comparable (p > 0.05) between the CON and WW diets but significantly lower in LM and BN groups. Yield of greasy wool was lower (p < 0.05) in BN group. Comparable dry matter and nutrient (crude protein and total digestible nutrients) conversion efficiency was observed on CON and WW diet but the lambs on the LM and BN...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
