This trial was conducted to investigate whether β-hydroxy β-methyl butyrate (HMB) supplementation during late gestation and throughout lactation would influence colostrum and milk production of sows and neonatal piglet survival (0 to 24 h). Control sows (CON; n = 8) were fed a standard lactation diet from day 108 of gestation and until 28 d after parturition (weaning). Sows fed HMB (n = 8) were...

background: human β-like globin genes regulaon during development from embyonic to adult stage results in generaon of different types of hemoglobin with different funcons. as β-thalassemia and sickle cell disease are disorders of β-globin chain, epigenec drugs such as thalidomide and sodium butyrate which can induce γ-globin gene are considered as a novel therapeuc approach. drugs effecve...

Backgrounds: Subclinical ketosis can cause greater economic loss due to a lack of clinical symptoms. Objectives: The present study was aimed to design a chemical method for measuring serum ketone bodies in the affected subclinical cows. Methods: Acetoacetate concentrations were measured using a nitroprusside reaction and b-hydroxy butyric acid (BHBA) which was oxidized to acetoacetate using nan...

Background: Ovarian cysts are among the diseases which cause reproductive failure and economic losses in dairy herds. High yelding dairy cattles are suseptable to reproductive failure caused by ovarian cysts, as a result of their exposure to stressful coditions during lactation. OBJECTIVES: This study aimed to monitor metabolic profile tests in dairy cows with ovarian cysts in comparison with c...

In studies where D-(-)-3-hydroxy[4,4,4-2H3]butyrate is employed as isotopic tracer in vivo, we have described a selected ion monitoring, gas-liquid chromatography-mass spectrometry micromethod which measures [2H3] tracer enrichment in 3-hydroxybutyrate and acetoacetate from 300-microliters blood samples. For plasma samples in the physiologic range, intra- and interassay precisions for each keto...

Cereal β-glucan may be detrimental in pig production because of negative effects on nutrient digestibility, but they may act as functional ingredients by stimulating the intestinal microbiota. This study primarily aimed to investigate relations between dietary β-glucan and nutrient digestibility, intestinal fermentation, and manure NH3 emission in weaned, growing, and finishing pigs. Effects of...

OBJECTIVES Total knee arthroplasty (TKA) performed in knee osteoarthritis patients is reported to be immediately followed by a decrease in quadriceps muscle strength. We investigated the effects of supplementation with a combination β-hydroxy-β-methyl butyrate, L-arginine, and L-glutamine (HMB/Arg/Gln) on the postoperative recovery of quadriceps muscle strength in patients after TKA. METHODS ...

The maintenance of muscle mass and muscle strength is important for reducing the risk of chronic diseases. The age- related loss of muscle mass and strength is associated with adverse outcomes of physical disability, frailty and death. β-Hydroxy β-Methyl Butyrate (HMB), a metabolite of leucine, has beneficial effects on muscle mass and strength under various catabolic conditions. The objectives...

A multicatheter sow model was established to study the effects of dietary β-hydroxy β-methyl butyrate (HMB) supplementation on net portal flux (NPF) and net hepatic flux (NHF) of HMB, glucose, and the AA Ala, Gly, Ile, Leu, Phe, Tyr, and Val. Eight second parity sows were fitted with permanent indwelling catheters in an artery and in the portal, hepatic, and mesenteric veins. Eight hourly sets ...

Achillea tenuifolia Lam (Asteraceae) afforded a methanolic extract from which after fractionation in solvents with different polarities two known flavones 3’, 5- dihydroxy- 4’, 6, 7- trimethoxy flavone (eupatorine, compound 3), 5- hydroxy- 3’, 4’, 6, 7- tetramethoxyflavone (compound 4), besides stearic acid (compound 1 ), lupeol (compound 2), daucosterol (β- sitosterol 3-O- β- D- glucopyranosid...
