“…PVA has excellent biocompatibility and can be used as wound dressings and drug-loading polymer substrates . ChCl can be used in the treatment of fatty liver and also as a feed additive for livestock, so it also has excellent biocompatibility . More importantly, the blending process only involves water.…”

Wearable elastic electronic devices have attracted tremendous attention due to their monitoring capabilities for human motion detection. In this work, a hydrogen bond acceptor quaternary ammonium salt, choline chloride (ChCl), has been used to fabricate deep eutectic polymer (DEP) blends with polyvinyl alcohol (PVA). The miscibility, molecular interaction, and physical properties of PVA/ChCl DEP blends were investigated systematically. It is demonstrated that the deep eutectic of PVA/ChCl can be obtained by simple solution blending, and the melting points of both PVA and ChCl are reduced respectively due to the strong hydrogen bond between PVA and ChCl. Due to the elasticity of the PVA/ChCl elastomer and the response of ChCl ions to temperature and humidity, the fabricated sensor showed stable and repeatable resistance changes upon strain, temperature, and humidity variations. We hypothesize that the DEP blend system has potential applications in functional composites and the final PVA/ChCl elastomer composites exhibited high transparent, antifreeze, and recyclable capability, which may be promising for applications in soft/flexible devices.

“…The role of choline chloride can be mediated by betaine, which reduces osmotic pressure [ 38 ] and improves placental efficiency. Moreover, the higher placental efficiency of PG, MS, RPC, and PMC ewes compared with RF ewes may be due to the higher nutrient supply, especially glucose, since an increase in serum glucose level by administration of these three compounds has been previously reported [ 12 ].…”

“…Moreover, it is clear that there is a positive relationship between placental efficiency and lamb morphological characteristics (r 2 = 50.3) [ 11 ], and an increase in nutrient flow through the placenta leads to an increase in body size. Considering the increased placental efficiency ( Table 2 ) and the previously noted increase in glucose and insulin levels in response to the administration of propylene glycol, monensin sodium, and rumen-protected choline chloride [ 12 ], which affect the growth and development of the offspring, administration of these additives to the ewes was expected to improve the conformation indices of the lambs.…”

“…Only the ewes that showed no signs of a second estrus 17–20 days after mating and became pregnant after the first estrus were further evaluated. Therefore, forty-eight 2–3-year-old Ghezel ewes (body weight (BW) = 65.53 ± 6.90 kg; body condition score (BCS) = 3.17 ± 0.56) were involved in this experiment (these ewes and this experiment are those whose data and results have been published in part in previous articles [ 12 , 13 ]). After mating, the ewes were allowed to graze on their native rangeland.…”

“…In late pregnancy, feeding supplements that increase the nutrient supply to the dam, and thus to the growing fetus, may mitigate the negative effects of maternal dietary restriction. Feed additives such as propylene glycol, monensin sodium, and choline chloride can improve blood glucose levels [ 12 ] and the energy status of ewes in several ways, including increasing dietary energy concentration, altering rumen fermentation to produce more propionate [ 13 ], and improving hepatic lipid metabolism. Since the fetus has a limited ability for glucose synthesis as the main substrate for fetal metabolism, the use of these supplements may promote fetal growth and development.…”

To evaluate the effects of supplementation of feed additives in the last trimester of pregnancy on placental characteristics and offspring performance, this study was conducted with 48 estrous-synchronized Ghezel ewes that had randomly been assigned to one of the following six groups (n = 8): ad libitum feeding (AL); feed restriction (RF; 60% of ad libitum intake); feed restriction + propylene glycol (PG); feed restriction + propylene glycol + monensin sodium (MS); feed restriction + propylene glycol + rumen-protected choline chloride (RPC); feed restriction + propylene glycol + monensin sodium + rumen-protected choline chloride (PMC). Birth weight, body size, and rectal temperature of lambs were determined within 24 h of birth. The presence of lambs at 87 days of age was used as an index of survival to weaning. The outcome of this study was that the average placental weight of ewes in the AL and MS groups was the highest and lowest, respectively, among the treatment groups (p < 0.01). RPC ewes presented higher placental efficiency compared to AL, RF, and MS ewes (p < 0.05). The largest and smallest crown-to-rump lengths (CRLs) were observed in PMC and RF lambs, respectively (p < 0.01). In addition, lambs born from PMC, RPC, and PG ewes had a longer curved crown-to-rump length (CCRL) than those born from AL and RF ewes (p < 0.01). The concurrent administration of propylene glycol and rumen-protected choline chloride resulted in the highest birth weight among treatment groups (p < 0.01). Lambs born to PMC and RPC ewes had a higher survival rate and rectal temperature than those born to RF ewes (p < 0.05). It can be concluded that although dietary restriction does not have adverse effects on lambs’ performance compared with ad libitum intake, the combined administration of propylene glycol and rumen-protected choline chloride in the ewes’ restricted diet can improve placental characteristics and subsequently amend lambs’ birth weight and body size. Therefore, the combined administration of these additives can be practiced during feed restriction.

BackgroundGrazing in arid and semi‐arid regions faces pregnant ewes with feed restrictions and hence affects the offspring muscle fibre characteristics. Using feed additives that enhance nutrient availability during foetal muscle development is expected to alter offspring skeletal muscle characteristics.ObjectivesThis study evaluated the effect of maternal restricted nutrition and supplementation of propylene glycol, monensin sodium and rumen‐protected choline chloride on lamb's muscle fibre characteristics.MethodsForty‐eight Ghezel ewes were randomly allocated to one of six diets (N = 8) during the last 6 weeks of gestation: ad libitum feed intake (AL); restricted feeding (RF); restricted feeding containing propylene glycol (PG); restricted feeding containing propylene glycol and monensin sodium (MS); restricted feeding containing propylene glycol and rumen‐protected choline chloride (RPC); restricted feeding containing propylene glycol, monensin sodium and rumen‐protected choline chloride (PMC). The muscle samples were obtained from the semitendinosus muscle of 2‐week‐old male lambs (n = 5/treatment) via biopsy and were stained and classified as fibre types I, IIA and IIB.ResultsPre‐parturient maternal feed restriction and administration of propylene glycol, monensin sodium and rumen‐protected choline chloride had no significant effect on fibre‐type composition, fibre density of muscle, muscle cross‐sectional area and volume density of fibres (p > 0.05).ConclusionsEither maternal dietary restriction or supplementation of nutrient flux–involved additives during late pregnancy did not alter muscle fibre development and had no short‐term effects on muscle properties of the resulting offspring as myogenesis occurs in early and mid‐gestation, not late gestation. Therefore, maternal nutrition may not be a problematic issue in sheep production in arid and semi‐arid areas.
