Johnson G, Bazer F, Burghardt R, Seo H, Wu G, Cain J, et al.
Reproduction
. 2024 Jul;

PMID: 38929408
Although both L-glutamate (Glu) and L-glutamine (Gln) have long been considered nutritionally nonessential in ruminants, these two amino acids have enormous nutritional and physiological importance. Results of recent studies revealed...

. 2024 Jun;
111(3):694-707.
PMID: 38836439
In pigs, the majority of embryonic mortality occurs when free-floating conceptuses (embryos/fetuses and associated placental membranes) elongate, and the uterine-placental interface undergoes folding and develops areolae. Both periods involve proliferation,...
