“…However, increased serum glucose concentrations were observed with 14 g/d NA (Karkoodi and Tamizrad, 2009) and 6 g/d NA (Aschemann et al, 2012). Several studies corroborated this result (El-Barody et al, 2001;Neihoff et al, 2009b;Pescara et al, 2010). It is not known whether the effect of increased glucose concentration in the blood with NA supplementation is due to increased gluconeogenesis due to greater availability of coenzymes (NAD and NADP) and propionate, decreased extra-hepatic removal of glucose, or endocrine changes promoted by inhibiting lipolysis (Zimmerman et al, 1992;Di Costanzo et al, 1997;El-Barody et al, 2001).…”

Nicotinic acid (NA) has been shown to reduce lipolysis, alter milk components and the ruminal environment, and increase blood flow. Increased blood flow to the mammary gland during colostrogenesis might increase nutrients and immunoglobulin concentration of colostrum. Twenty-six multiparous Holstein cows were housed in a tiestall barn. Cows were blocked by expected calving date and randomly assigned to 1 of 2 treatments 4 wk prepartum: (1) 0g/d of NA (control, CON) or (2) 48g/d of NA (NA). Total mixed ration amounts fed and refused were measured daily to determine dry matter intake. Blood samples were collected from dams every Monday, Wednesday, and Friday from the coccygeal vein or artery and were analyzed for glucose, nonesterified fatty acids (NEFA), and β-hydroxybutyrate (BHB). Colostrum was collected and weighed within 90 min of parturition. Colostral immunoglobulin G (IgG) concentration was analyzed using radial immunodiffusion assay. Calves were removed from their dams before suckling and weighed within 30 min after birth. Calves received 3 L of a lacteal-based colostrum replacer that provided a total of 225.8g of IgG within 2h of birth. Calf blood samples were collected via jugular venipuncture at 0 and 24h of age and analyzed for IgG concentration and determination of apparent efficiency of absorption. Colostrum yield, dry matter intake, IgG yield, and fat and solids percentage of colostrum did not differ between treatments. Serum concentrations of glucose and BHB were not affected by treatment. We detected an effect of week on serum glucose concentrations at calving and on serum BHB concentrations at 1 wk postpartum. There was a treatment by week effect for serum NEFA concentrations at 1 wk postpartum, where cows that received NA prepartum had higher serum NEFA concentration than CON cows, indicating that a NEFA rebound occurred. No differences were observed for calf body weight, 0- or 24-h serum IgG concentration, or apparent efficiency of absorption. Supplementation of NA increased IgG concentration in colostrum from 73.8 to 86.8g/L. Results indicate that 48g/d of supplemental NA during the prepartum period improved colostrum quality.

“…In contrast, Ghorbani et al (2008) reported that the concentration of serum GLU increased, whereas the concentration of TG and TP decreased in dairy cows when diets were supplemented with niacin during the early lactation period. El- Barody et al (2001) supplemented feed with either 6 or 12 g niacin/head per day and reported a decrease in serum TC concentration in pregnant Egyptian buffaloes. This observation was in agreement with the findings of a study published by Kumar and Dass (2006) in male buffalo calves.…”

In the present study, the effect of niacin supplementation on the growth performance and nutrient utilisation in Chinese Jinjiang cattle was investigated. A total of 48 finishing male Jinjiang cattle aged 24-30 months, with body weights of 200 ± 15 kg, were randomly divided into four groups. The cattle were fed a finishing diet (concentrate to forage ratio of 80:20). The diets for the control, NA 320 , NA 480 and NA 640 groups were supplemented with 0, 320, 480 or 640 mg/kg of niacin, respectively. The body weight and feed consumption of the 48 cattle were recorded on days 1, 28, and 56 of the experiment. Assessment of feed digestibility was conducted from days 52 to 56 of the study. Blood samples were collected from each animal on day 56. From days 1 to 56 of the study, the results indicated a significant increase in the average daily weight gains (p < .05) and lower feed to gain ratios (p < .05) for the NA 480 and NA 640 groups than for the control group. Furthermore, supplementation with 640 mg/kg niacin increased the apparent digestibility of all nutrients (p < .05), whereas supplementation with 480 mg/kg niacin enhanced the apparent digestibility of crude protein (p < .05). Moreover, supplementation with 480 and 640 mg/kg niacin increased the content of serum nonesterified fatty acids (p < .05). Therefore, it was concluded that supplementation with 640 mg/kg niacin in a high-concentrate diet may be beneficial to growth and nutrient utilisation in Chinese Jinjiang cattle.

“…Canfield and Butler (1990) found a strong correlation between negative energy balance in early lactation and resumption of ovulation with activity LH which probably induced follicle growth and oocyte maturation in cattle. Furthermore, El-Barody et al, (2001) indicated that improving feed utilization and energy mobilization is the major limiting key element dictating an early ovulation in dairy buffaloes during the first few weeks after calving by enhanced nutrient availability which stimulate the ovary or other parts of the hypothalamic-pituitary-ovarian axis and may avoid stimulation of gonadotropin secretion. In this respect, AbdelKhalek (2003) recorded improvement in days to first breeding, day open, service period and number of services per conception, but the differences were not significant of multiparous Friesian cows fed diets with Yea-Sacc as YC.…”

Twenty dairy buffaloes at late pregnancy and in 2-4 parties were divided into four groups fed control ration (G1), or the control ration with 10 g yeast (YC)/h/d (G2), 10 g/h/d fibrolytic enzyme (FENZ, G3) and 10 g YC+10 g FENZ/h/day (G4). The feeding period lasted from three months pre-partum up to 100 days postpartum. Results indicated that digestibility of DM, OM, CP, feeding values as TDN and DCP, actual and 7% FCM milk yield, percentages and components yield of milk and feed efficiency improved (P<0.05) by all treatments. Plasma total proteins, albumin, globulin and glucose increased (P<0.05) by FENZ. Ruminal pH value decreased insignificantly, while total volatile fatty acids and ammonia-N concentrations increased (P<0.05) with YC and FENZ. Supplementation with FENZ improved (P<0.05) calf birth weight (CBW), CBW/post-partum dam weight, weight at weaning, and daily and total gain. Reproductive traits improved by FENZ supplementation, in terms of decreasing (P<0.05) duration of placental drop and uterine involution, 1st heat incidence, days open and number of services per conception. Supplementation of YC and FENZ decreased (P<0.05) the cost of kg 7% FCM, and increased (P<0.05) income of 7% FCM, reflecting the highest economic feed efficiency.Pre-and post-partum diets supplemented with yeast culture and fibrolytic enzyme are beneficial to the digestibility, rumen fermentation, blood metabolites, milk production, feed conversion rate, economic feed efficiency, and postpartum reproductive performance of Egyptian buffaloes and growth performance of their offspring during suckling period.
