Example: "The absence of feed during the winter months can lead to serious health issues for livestock."
Alternatives: "lack of feed" or "shortage of feed".
The primary initiation step in the absence of feed olefins is the dehydrogenation of butane over sulfated-zirconia, generating butenes which adsorb onto acid sites.
In the absence of feed NO, the dual-layer catalyst has a high selectivity to N2 due to the selective reaction in the Cu SSZ-13 layer between NH3 from the bulk and Cu SSZ-13iffusing NOx formed in the underlayer Pt/Al2O3.
The age of the inoculated chickens, using new or used litter, Salmonella inoculation dose, and presence or absence of feed additives are a few examples of factors which may influence the time and amount of Salmonella being excreted by chickens.
It is widely accepted that disorders caused by EW, including increased susceptibility to diarrhea and growth retardation, mainly result from the transient absence of feed consumption that follows EW [ 1].
It is possible that RER whorls function by providing a mechanism to rapidly activate midgut secretion pathways upon feeding, rather than expend energy maintaining them in the absence of feeding.
Solitary foraging per se cannot explain the absence of feeding competition in L. leucopus as other species of solitary foragers were found to experience feeding competition.
Included were age groups, presence or absence of feeding tube, LOS of 2 years or less, CCI score and functional resident groups (fully dependent vs mobile demented residents).
In years prior to 1993, and in dekads prior to the end of April, DMDMAT commonly fell between 7°C (the threshold for nymphal activity) and 10°C (Figs. 5, 6), therefore permitting nymphs to feed in the absence of co-feeding larvae.
As described by 21, mice on a CR regime consume their daily single food allotment immediately followed by a prolonged period of absence of food (mice fed AL spread their food intake over the day).
This leads to poor calf health in the absence of commercial feed supplementation.
The increased amount of foulant on the membranes, compared to offline salt cleaning, could also have been due to the absence of high feed cross-flow velocity, which could have helped to flush out some of the foulants from the membrane surface.
