Standardized ileal digestibility coefficients (SIDC) of nitrogen (N) and amino acids (AA) in two protein sources (soybean meal [SBM] and canola meal [CM]) were investigated at six broiler ages (d 7, 14, 21, 28, 35, and 42). Two assay diets were formulated to contain either SBM (413 g/kg) or CM (553 g/kg) as the sole dietary AA source. Titanium dioxide (5 g/kg) was added as an indigestible marker. A total of 696 male broilers at 1 d old were allotted to 12 replicate cages per age group. Each assay diet was offered to birds for 4 d prior to the ileal digesta collection on d 7 (14 birds/cage), 14 (12 birds/cage), 21 (10 birds/cage), 28 (8 birds/cage), 35 (8 birds/cage) and 42 (6 birds/cage), respectively. The apparent digestibility coefficients were standardized using age-specific basal endogenous AA flows. In the SBM group, though the SIDC of N tended to be influenced (quadratic; P=0.075) by age, no linear or quadratic response of age effect was observed on the average SIDC of indispensable (IAA) and total AA (TAA). An age effect (quadratic; P<0.05) was observed on the average SIDC of dispensable AA (DAA) in SBM with the highest value recorded at d 7, followed by a decrease from d 14 to 28, which increased beyond d 35. The SIDC of some individual AA (Arg, Thr, Trp, Cys, Pro) were affected (P<0.05 or P<0.001) in a quadratic manner by age. In the CM, the SIDC of N, average SIDC of IAA, DAA and TAA were influenced (quadratic; P<0.05 or P<0.001) by age. The SIDC of N and average SIDC of DAA and TAA were higher from d 7 to 14, declined at d 21, and then increased beyond d 28. The average SIDC of IAA was low between d 7 and 28 and increased thereafter. The SIDC of individual AA were affected (linear or quadratic; P<0.05 or P<0.001) by different magnitudes by age. The age influence on the SIDC AA was variable, depending on the protein source and AA. The results demonstrate that age-specific SIDC AA data might need consideration in broiler feed formulations.

Chemotherapy is an effortless and frequently used approach in cancer therapy.However,in most cases,it can only prolong life expectancy and does not guarantee a complete cure.Furthermore,chemotherapy is associated with severe adverse effects,one of the major complications of effective cancer therapy.In addition,newly published research outputs show that cancer stem cells are involved in cancer disease progression,drug resistance,metastasis,and recurrence and that they are functional in the trans-differentiation capacity of cancer stem cells to cancer cells in response to treatments.Novel strategies are therefore required for better management of cancer therapy.The prime approach would be to synthesize and develop novel drugs that need extensive resources,time,and endurance to be brought into therapeutic use.The subsequent approach would be to screen the anti-cancer activity of avail-able non-cancerous drugs.This concept of repurposing non-cancer drugs as an alternative to current cancer therapy has become popular in recent years because using existing anticancer drugs has several adverse effects.Micronutrients have also been investigated for cancer ther-apy due to their significant anti-cancer effects with negligible or no side effects and availabil-ity in food sources.In this paper,we discuss an ideal hypothesis for screening available non-cancerous drugs with anticancer activity,with a focus on cancer stem cells and their clinical application for cancer treatment.Further,drug repurposing and the combination of micronu-trients that can target both cancers and cancer stem cells may result in a better therapeutic approach leading to maximum tumor growth control.

The compromised egg quality and leg abnormality during the end of the laying cycle(after 40 weeks)have been leading to poor animal welfare and substantial economic losses. Therefore, the effects of fermented calcium(Ca) butyrate, produced by fermentation by Clostridium butyricum, on production,eggshell quality, and tibial property of hens were explored. A total of 192 Hy-line brown laying hens at50-week-old were assigned to a basal diet or the basal diet with 300 mg/kg of the fermented Ca butyrate from 50 to 58 weeks of age. Each treatment had 6 replicates with 16 hens each. The diet supplemented with 300 mg/kg fermented Ca butyrate notably increased egg weight, ovarian follicle number, and eggshell strength(P = 0.072) as compared to the basal diet, which were associated with cytokine secretion, toll-like receptor signaling pathways, and intestinal immunity based on the RNA-seq data from the granulosa. Dietary Ca butyrate inclusion decreased the expression of ileal tumor necrosis factor-alpha and serum pro-inflammatory cytokine concentration, as well as increased the content of serum immunoglobulin A when compared to the basal diet(both P 0.05). In addition, the diet with fermented Ca butyrate reduced the number of osteoclasts in the proximal tibia and the level of C-terminal cross-linked telopeptide of type I collagen, a bone resorption marker(P < 0.05), whereas it tended to increase the concentration of the procollagen type I N-terminal propeptide that reflects bone formation marker in serum. Moreover, the layers fed fermented Ca butyrate diets possessed higher(P < 0.05) bone area and trabecular number of the proximal tibia, yield load, and ultimate load than those that consumed basal diets. Collectively, dietary fermented Ca butyrate supplementation in post-peak layer diets improved the ovari

The cellular prion protein(PrPC),a cell surface glycoprotein of 209 amino acids,has been considerably studied over the decades mainly due to its critical involvement in transmissible spongiform encephalopathies,or prion diseases.Indeed,it is the misfolding and aggregation of PrPC into pathological assemblies-named PrPSc-that constitute prions,the agents causing these unusual neurodegenerative diseases affecting humans and animals(Prusiner,1982).Furthermore,increasing evidence support its relevance also in other neurodegenerative diseases(NDDs),such as Alzheimer’s and Parkinson’s diseases(Corbett et al.,2020).

Background Vitamin A(VA)and its metabolite,retinoic acid(RA),are of great interest for their wide range of physiological functions.However,the regulatory contribution of VA to mitochondrial and muscle fiber composition in sheep has not been reported.Method Lambs were injected with 0(control)or 7,500 IU VA palmitate into the biceps femoris muscle on d 2 after birth.At the age of 3 and 32 weeks,longissimus dorsi(LD)muscle samples were obtained to explore the effect of VA on myofiber type composition.In vitro,we investigated the effects of RA on myofiber type composition and intrinsic mechanisms.Results The proportion of type I myofiber was greatly increased in VA-treated sheep in LD muscle at harvest.VA greatly promoted mitochondrial biogenesis and function in LD muscle of sheep.Further exploration revealed that VA elevated PGC-1αmRNA and protein contents,and enhanced the level of p38 MAPK phosphorylation in LD muscle of sheep.In addition,the number of type I myofibers with RA treatment was significantly increased,and type IIx myofibers was significantly decreased in primary myoblasts.Consistent with in vivo experiment,RA significantly improved mitochondrial biogenesis and function in primary myoblasts of sheep.We then used si-PGC-1αto inhibit PGC-1αexpression and found that si-PGC-1αsignificantly abrogated RA-induced the formation of type I myofibers,mitochondrial biogenesis,MitoTracker staining intensity,UQCRC1 and ATP5A1 expression,SDH activity,and enhanced the level of type IIx muscle fibers.These data suggested that RA improved mitochondrial biogenesis and function by promoting PGC-1αexpression,and increased type I myofibers.In order to prove that the effect of RA on the level of PGC-1αis caused by p38 MAPK signaling,we inhibited the p38 MAPK signaling using a p38 MAPK inhibitor,which significantly reduced RA-induced PGC-1αand MyHC I levels.Conclusion VA promoted PGC-1αexpression through the p38 MAPK signaling pathway,improved mitochondrial biogenesis,and altered the composition of muscle fiber type.

Understanding how different livestock species and breeds respond to consumption of brackish water could improve usage of this resource.Therefore,Angora,Boer,and Spanish goat doelings and Dorper,Katahdin,and St.Croix ewe lambs (6 animals per animal type[AT];initial age=296±2.1 days)consuming water with varying concentrations of minerals of a natural brackish water source (BR) and sodium chloride (NaCl;SL) were used to determine effects on water and feed intake,nutrient digestion,heat energy,methane emission,ruminal fluid conditions,and blood constituent concentrations.There were 6 simultaneous 6 (water treatments[WT])×6 (AT) Latin squares with 3-wk periods.The WT were fresh (FR),BR alone (100-BR),a similar total dissolved solids (TDS) concentration as 100-BR via NaCl addition to FR (100-SL),BR with concentrations of all minerals increased by approximately 50%(150-BR),a similar TDS level as 150-BR by NaCl addition to FR (150-SL),and a similar 150 TDS level achieved by addition of a 1:1 mixture of BR minerals and NaCl to 100-BR (150-BR/SL).Concentrations (mg/kg) in BR were 4928 TDS,85.9 bicarbonate,224.9 calcium,1175 chloride,60.5 magnesium,4.59 potassium,1387sodium,1962 sulfate,and 8.3 boron,and TDS in other WT were 209,5684,7508,8309,and 7319 mg/kg for FR,100-SL,150-BR,150-SL,and 150-BR/SL,respectively.There were very few significant effects of WT or AT×WT interactions,although AT had numerous effects.Water intake was affected by AT (P=0.02)and WT (P=0.04),with greater water intake for 150-SL than for FR,100-BR,100-SL,and 150-BR.Dry matter intake among AT was lowest (P<0.05) for Angora.Digestion of organic matter and neutral detergent fiber and heat energy differed among AT (P<0.05),but nitrogen digestion and ruminal methane emission were similar among AT.Blood aldosterone concentration was higher (P<0.05) for FR than for other WT.In conclusion,all AT seemed resilient to these WT regardless of mineral source and concentrations,with TDS less than 8300 mg/kg,which did not influence nutrient utilization,ruminal ferme
