“…However, prepartum DMI was significantly decreased with CAN and tended to decrease with SUN treatments. These findings are in general agreement with some (Moallem et al, 2007;Duske et al, 2009;Karimian et al, 2015) but not all (Afzalzadeh et al, 2010;Hayirli et al, 2011) reports of reduced DMI with prepartum fat supplementation. The inconsistencies among studies could likely be due to the amount and types of fat sources.…”

“…Plasma concentrations of cholecystokinin, GLP-1 and glucose dependent insulinotropic peptide were reported to be greater postpartum than prepartum in Holstein cows (Relling and Reynolds, 2007b;Larsen et al, 2010;Hayirli et al, 2011), whereas insulin and leptin concentrations were greater pre-compared with postpartum (Liefers et al, 2003;Kokkonen et al, 2005;Afzalzadeh et al, 2010). However, little is known of the effects of prepartum high fat diets on gut hormone concentrations.…”

“…However, little is known of the effects of prepartum high fat diets on gut hormone concentrations. Dietary fat supplementation prepartum has been shown to have no effect on plasma cholecystokinin (Hayirli et al, 2011) but decrease plasma leptin concentrations (Afzalzadeh et al, 2010); it is unknown whether other hormones are similarly modulated. Therefore, the objectives of this study were to determine the effects of prepartum dietary fat supplementation on plasma concentrations of GLP-1, PYY, adropin, insulin, and leptin during the pre-and postpartum periods and to assess whether these hormones are correlated with various parameters including DMI, BW, BCS, energy balance, and metabolites.…”

Dietary fat supplementation during the periparturient period is one strategy to increase energy intake and attenuate the degree of negative energy balance during early lactation; however, little is known of the underlying hormonal and metabolic adaptations. We evaluated the effects of prepartum fat supplementation on energy-balance parameters and plasma concentrations of glucagon-like peptide-1, peptide tyrosine-tyrosine (PYY), adropin, insulin, leptin, glucose, nonesterified fatty acid, and β-hydroxybutyric acid in dairy cows. Twenty-four pregnant dairy cows were randomized to diets containing either rolled canola or sunflower seed at 8% of dry matter, or no oilseed supplementation, during the last 5 wk of gestation and then assigned to a common lactation diet postpartum. Blood samples were collected at -2, +2, and +14 h relative to feeding, at 2 wk after the initiation of the diets, and at 2 wk postpartum. Dietary canola and sunflower supplementation alone did not affect energy balance, body weight, and plasma concentrations of glucagon-like peptide-1, PYY, adropin, insulin, leptin, nonesterified fatty acid, and β-hydroxybutyric acid; however, canola decreased and sunflower tended to decrease dry matter intake. We also observed that the physiological stage had a significant, but divergent, effect on circulating hormones and metabolite concentrations. Plasma glucagon-like peptide-1, PYY, adropin, nonesterified fatty acid, and β-hydroxybutyric acid concentrations were greater postpartum than prepartum, whereas glucose, insulin, leptin, body weight, and energy balance were greater prepartum than postpartum. Furthermore, the interaction of treatment and stage was significant for leptin and adropin, and tended toward significance for PYY and insulin; only insulin exhibited an apparent postprandial increase. Postpartum PYY concentrations exhibited a strong negative correlation with body weight, suggesting that PYY may be associated with body weight regulation during the transition period. These novel findings demonstrate that the transition from pregnancy to lactation is a stronger determinant of circulating gut hormone concentrations than dietary lipid in transition dairy cows.

“…High and prolonged insulin and Insulin–like growth factor I (IGF‐I) concentrations are critical for follicle and oocyte maturation and quality (Quesnel, Rodriguez‐Martinez, Vallet, & Ziecik, ). However, blood insulin levels can be decreased due to the low total content of carbohydrates in high‐fat diets (Afzalzadeh, Palizdar, Mahmoudzadeh, & Niasari‐Naslaji, ). Dextrose is a readily absorbable carbohydrate that can raise plasma insulin concentration quickly after ingestion (Wientjes et al, ).…”

This study investigated the litter performance of lactating sows fed nutrient‐dense diets with or without dextrose at farrowing to weaning, during the summer with an average room temperature of 28.4°C. A total of 60 (13 first parity, 13 second parity, 19 third parity, and 15 forth parity) cross‐bred sows were assigned to three treatments. The three treatments were: standard diet (ST), high nutrient diet (HN; ST + 3% higher energy and 18.0% protein), and high nutrient diet plus dextrose (HND; 3% higher energy, 18.0% protein, and 5% dextrose). BW loss was reduced in the HND sows compared with the ST sows during lactation. The HN and HND sows had a higher piglet and litter weight at weaning. Also, the HND sows had the highest post‐prandial insulin levels at weaning and the shortest weaning‐to‐service interval (WSI). Serum LH was higher in the HND sows than the ST sows. The milk fat level was higher in the HND sows compared with the ST sows, but similar to the HN sows. In conclusion, these results suggest that it is possible to increase the blood insulin response by supplementing dextrose to a high nutrient diet, thus, improving WSI interval and litter growth during heat stress.

“…In addition, previous studies have reported no effect of soybean oil supplementation on milk protein content (Zheng et al, 2005;Bu et al, 2007). In another study Afzalzadeh et al, (2010) revealed that feeding fat at prepartum period may help animals to use fat sources for energy requirements and consequently other sources of energy such as amino acids (glucogenic precursors) could be used for other functions like protein synthesis and milk production. Likely due to increase milk production, milk protein yield was significantly (P < 0.05) greater by cows fed fat treatments than cows fed CON treatment.…”

his study was conducted at North Carolina State University, USA. Primiparous (n=9) and multiparous (n=17) Holstein cows were utilized in a completely randomized block design. Three treatments were as follows : (1) control treatment (CON) without fat supplementation ; (2) unprotected fat treatment (UF), which fat supplemented as soybean oil; (3) protected fat (PF), which fat supplemented as Megalac. Fats were supplemented to the cows diets beginning at 21 days prior to expect calving date through 60 days postpartum. Supplemental fats were fed at 2% and 3% dietary dry matter (DM) during prepartum and postpartum periods, respectively. Milk production measured daily. Milk fat, protein, lactose and solids not fat (SNF) were analyzed at day 0, 30 and 60 postpartum. The results indicated that, prepartum dry matter intake (DMI) was not significantly different across treatments. However, fat supplementation decreased postpartum DMI compared to the CON treatment. Cows fed PF beginning in the prepartum period produced more milk and higher FCM than cows fed UF and CON treatments. Feeding PF numerically increased milk fat percentage compared to the CON and UF diets, but the difference was not significant among treatments. However, PF treatment tended to decreased (P=0.10) milk protein percentage compared to CON and UF treatments. Feeding fat did not alter milk lactose and solids not fat percentages in comparison with CON diet. Feed efficiency, expressed as kg of 3.5% FCM per kg of DM intake, was significantly higher when feeding fat treatments than feeding CON. Concentration of C8:0 in milk fat tended to be higher (P=0.10) in cows fed fat compared to CON treatment. Fat supplementation had no significant effect on production of C12:0 , C14:0 , C15:0 , C18:1 and C18:2 in milk fat. However, significant differences were found in C10:0, C16:0 and C18:0 in UF and PF treatments compared to CON treatment. From the present results it can be concluded that supplementation of protected fat in the rations of high producing dairy cows during prepartum and postpartum led to positive effect on milk production and milk composition.
