“…This is in agreement with most other research (Driver et al, 1990;Jaster & Ward, 1990;Martinez et al, 1991;Christensen et al, 1992;Zimmerman et al, 1992;Campbell et al, 1994;Bernard et al, 1995;Ottou et al, 1995;Minor et al, 1998).

In this experiment the response to niacin supplementation was evaluated. Twelve multiparous Holstein cows were used in a replicated 4 × 4 Latin square statistical model in four 24 d periods as replicates. At the onset all the cows were in early lactation with days in milk (DIM) at 60.1 ± 16.1 and an average milk yield of 31.4 ± 5.44 L/d. The treatments were: N0 -control (no niacin supplement); N1 -control + 12 g niacin/d; N2 -control + 14 g niacin/d and N3 -control + 16 g niacin/d. Means were compared with the Duncan ' s least range test. Milk yield, fat-corrected milk (FCM, 3.5%) and total solids percentage (TS) were significantly higher in the N2 compared to the other treatments. There were no significant differences between treatments in milk fat and milk lactose percentages, but milk fat yield was significantly higher and milk fat percentage numerically higher in the N2 than in the other treatments. Milk protein yield and percentage were highest in N2, but milk protein percentage was not significantly different between the N2 and N1 treatments. Milk solids non-fat (SNF) percentage was the highest for N2. Evaluation of blood plasma parameters showed that 14 g niacin (N2) supplementation resulted in a significantly higher glucose concentration and the lowest ß-hydroxybutyrate (BHBA) and nonesterified fatty acids (NEFA) concentrations as compared to the other treatments. This study suggested that the optimal level of niacin supplementation was 14 g niacin/cow/d. .

“…These results are similar to those of studies by DiCostanzo et al (1997), which investigated the effects of 12 g, 24 g and 36 g supplemental niacin in cows (90 d of lactation) over three consecutive 17-d periods. This matches numerous investigations performed earlier with lower levels of niacin (Erickson et al, 1990;Martinez et al, 1991 andChristensen et al, 1996). However, when only the primiparous cows that received niacin were considered, increased milk yield could be found in early lactation, which agrees with other studies (Jaster & Ward, 1990;Young & Smith, 1994).…”

“…In agreement with Jaster & Ward (1990), Martinez et al (1991) and Erickson et al (1992), DMI was not affected by supplemental niacin. In Groups 60 + NA and 60−, in early lactation (up to the seventh week) DMI increased faster than in Groups 30 + NA and 30−.…”

“…In most earlier studies significant effects could not be detected on blood glucose concentration due to niacin (Martinez et al, 1991;Erickson et al, 1992 andLanham et al, 1992). Only a few studies recorded increased glucose concentration (Ghorbani et al, 2008;Karkoodi & Tamizrad, 2009).…”

“…However, if cows and heifers were considered separately in week 1 of lactation, the niacinsupplemented cows and heifers of Group 60 + NA had lower NEFA concentrations than Group 60− (Figure 8). Martinez et al, 1991 detected increases in NEFA concentration, but in their trial fat was also supplemented. Decreases in NEFA were also observed by and , but in feed-restricted, non-lactating, non-gestating cows.…”

The present study was conducted to investigate the effects of 24 g niacin (nicotinic acid (NA)) supplementation over 40 weeks with two forage-to-concentrate ratios (60% concentrate vs. 30% in the total diet) on performance variables of energy metabolism such as plasma concentrations of non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), glucose and nicotinamide (NAM), and the fatty acid profile in rumen fluid. In a 2 x 2 factorial design, 64 German Holstein cows were divided postpartum into four dietary groups: i) 60% concentrate supplemented with 24 g NA (Group 60 + NA); ii) 60% concentrate without NA (Group 60−); iii) 30% concentrate with 24 g NA (Group 30 + NA) and iv) 30% concentrate without NA (Group 30−). The experiment started on the day of calving and continued for 40 weeks. Niacin supplementation did not affect milk yield or composition. The plasma niacin content increased in the supplemented groups, especially Group 30 + NA. Niacin supplementation led to decreased plasma glucose concentrations. The interaction of concentrate x niacin enhanced the molar proportion of propionic acid in rumen fluid in Group 60 + NA. Total short-chain fatty acid (SCFA) concentrations were increased by level of concentrate, niacin supplementation and the interaction, concentrate x niacin. Plasma levels of NEFA and BHB remained unaffected. In sum, concentrate level, niacin supplementation and the interaction of concentrate x niacin increased plasma NAM concentration, whereas plasma glucose concentration was decreased by niacin supplementation. ______________________________________________________________________________________
