Abstract

Experiment was conducted on Jersey crossbred cows (12) to compare 2 management practices viz. hand andmachine milking. Field investigations were also carried out on other milking management practices, IMI, hygienestatus and cleanliness in 3 stages. A total of 459 milk samples were analysed. Farm experimentation revealed thatSCC and MCMT were significantly higher in hand milking as compared to machine milking management. Butmilk yield and milk extraction rate were significantly lower in hand milking as compared to machine milkingmanagement. The time required for milking/animal was significantly higher in hand milking as compared to machinemilking management. The morning and evening milk samples of both hand and machine milking showed highervalues of SCC, MCMT, pH during evening as compared to morning session but milk yield and milk extraction ratewere lower during evening as compared to morning session whereas time required for milking/animal was higherin morning as compared to evening time. Almost similar trend of fat and SNF (%) were estimated in both milkingsession. Field investigation indicated that SCC, MCMT, pH were higher in IMI animal as compared to no-IMIanimal whereas fat and SNF were lower in IMI animal as compared to...Continue Reading

COVID-19

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.

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.

Separation Anxiety

Separation anxiety is a type of anxiety disorder that involves excessive distress and anxiety with separation. This may include separation from places or people to which they have a strong emotional connection with. It often affects children more than adults. Here is the latest research on separation anxiety.

KIF1A Associated Neurological Disorder

KIF1A associated neurological disorder (KAND) is a rare neurodegenerative condition caused by mutations in the KIF1A gene. KAND may present with a wide range and severity of symptoms including stiff or weak leg muscles, low muscle tone, a lack of muscle coordination and balance, and intellectual disability.
