Two experiments are reported in which the effect of the intragastric infusion of non-protein energy on fasting nitrogen losses was studied. Expt 1 was a preliminary trial with two 35 kg lambs given 0, 144, 288 or 432 kJ/kg live weight (W)0.75 per d as lipid or glucose infused into the abomasum for periods of 3 d. Expt 2 was of a 4 X 4 Latin square design with four sheep of about 30 kg live weight. The four treatments were control (fasted with water infusion), or the infusion of 144 kJ/kg W0.75 per d as glucose or lipid into the abomasum or as acetic acid into the reticulo-rumen. Compared with the fasted control, glucose infusion reduced (P less than 0.05) N excretion to about 0.6 of that of the control, increased (P less than 0.05) plasma glucose, decreased (P less than 0.05) plasma urea and beta-hydroxybutyrate, and was without effect on plasma amino-N or creatinine excretion. Lipid and acetate infusions were without statistically significant effect on N or creatinine excretion or any of the blood indices measured, with the exception of plasma glucose which was reduced (P less than 0.05) with acetate infusion.

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.
