Abstract:
The objective of our study was to assess the effect of rumen-protected niacin supplementation on the transcriptome of liver tissue in growing Angus × Simmental steers and heifers through RNA-seq analysis. Consequently, we wanted to assess the known role of niacin in the physiological processes of vasodilation, detoxification, and immune function in beef hepatic tissue. Normal weaned calves (~8 months old) were provided either a control diet or a diet supplemented with rumen-protected niacin (6 g/hd/d) for a 30-day period, followed by a liver biopsy. We observed a significant list of changes at

Abstract:
Fescue toxicity is a nutritional-related disease generated in a forage-based beef herd exposed to ergot alkaloids (i.e. ergovaline) present in endophyte-infected tall fescue that produces important economic losses. The combination of a genetic test for susceptibility to fescue toxicity and supplementation with rumen-protected niacin could potentially reduce the toxic effects of ergovaline on beef cow and heifers’ reproductive performance during mid-gestation by improving uterine blood flow. Our main objective was to use color Doppler ultrasonography to evaluate the occurrence of any alteration

Abstract:
AbstractAs the precursor to NAD+ and NADP+, niacin is important for catabolic and anabolic redox reactions. In addition, niacin is known for its anti-lipolytic action via a hydroxycarboxylic acid-2-receptor-dependent mechanism. The anti-lipolytic effects of traditional free niacin supplementation during transition periods had been studied extensively, but the reported effects are ambiguous. In the past decade, a series of studies were conducted to evaluate the effects of rumen-protected niacin (RPN) on production performance and metabolic status in early lactation and on heat stress in dairy c

Abstract:
To investigate the difference between rumen-protected niacin (RPN) and rumen-protected nicotinamide (RPM) in the transcriptome of genes relating to the lipid metabolism of the liver of periparturient dairy cows, 10 healthy Chinese Holstein cows were randomly divided into two groups and fed diets supplemented with 18.4 g/d RPN or 18.7 g/d RPM, respectively. The experiment lasted from 14 days before to 21 days after parturition. Liver biopsies were taken 21 days postpartum for transcriptomic sequencing. In addition, human LO2 cells were cultured in a medium containing 1.6 mmol/L of non-esterifie

Niacin may cause evaporative thermolysis through cutaneous hyperemia, vasodilation, increased sweating rate and decreased skin temperature. It is antilipolytic and can improve metabolic responses. Heat stress ameliorative effects of rumen protected niacin (RPN) supplementation in lactating Surti buffaloes during summer has been investigated in present study. Fourteen lactating Surti buffaloes were divided into two groups (Control-T1, N=7; RPN-T2, N=7). T2 (RPN) group was supplemented with RPN 6 g/ animal/ day in two divided dose for 4 weeks.

Abstract:
Context Nowadays fat is an unpopular constituent of meat for consumers and therefore, a decrease in fat-tail size is often desirable for producers. Feed additives like chromium (Cr) and niacin (B3) have been reported to improve meat quality in beef and dairy cattle. However, their effect on meat quality and performance of fat-tail breeds of finishing lambs is unknown. Aim The aim of this study was to investigate the effect of supplemental chromium (Cr) and niacin (B3) on performance and fat deposition of carcass of finishing lambs.

Abstract:
Offspring born to dams genetically tested for resistance to fescue toxicity were separated in groups based on their dams’ resistance level (tolerant vs. susceptible). Rumen-protected niacin (RPN) is proposed as a potential alleviator for vasoconstriction produced by fescue toxicity. Complete blood count (CBC) analysis was utilized for detection of significant responses to treatments applied. Our objectives were as follows: (a) to analyze changes in CBC due to fescue toxicity, maternal resistance level, and RPN in growing offspring; and (b) to assess the effects of maternal resistance level whe

Abstract:
Abstract Fescue toxicity is the result of cattle consuming fungal (Ergot spp.) endophyte tall fescue, a perennial forage widely used in the United States. Ergot alkaloids produce vasoconstriction; however, rumen-protected Niacin (RPN), known by its vasodilation ability, may act as an alleviator for fescue toxicity. Our objective was to assess the effects of a genetic test for fescue toxicity susceptibility, and RPN supplementation on animal performance, hepatic gene expression, and uterine arteries blood flow of Angus × Simmental pregnant animals consuming endophyte-infected tall fescue seeds.

There have been limited field trials exploring the potential ameliorative effect of B-complex vitamin or antioxidant therapy in cows with prolonged insulin resistance (IR). The purpose of this study was to explore the effect of prepartum supplementation of niacin, choline and cod liver oil on metabolic status, indices of insulin sensitivity (IS) as well as markers of oxidative stress in cows with subclinical ketosis (SCK). For this purpose, 24 apparently healthy cows at ~3 weeks before the expected time of calving were studied. Based on their serum concentration of non-esterified fatty acid (N

Forty high producing early to mid lactation Holstein cows were blocked according to stage of lactation and previous two-week milk yield (experiment 1) . Eight ruminally and duodenally cannulated nonlactating Holstein cows were used for experiment 2. The objective was to determine the effects of the ration's high fat content (11.53%) when rumen degradable or rumen undegradable protein is fed with or without added niacin. Cows received one of five treatments: 1) basal ration (TMR); 2) basal ration with added rumen undegradable fat (RUF) (1.6 kg); soybean meal (SBM) (1.73 kg), and niacin (12 g);
