“…In present study the dietary intervention with HT helped to decrease the serum IgG and IgM levels which might positively be associated with digestibility of protein in rats [40]. However, the lack of experimental effect of HT was observed on the serum total protein which was in agreement with the previous study [41] and showed that HT had shown non toxic effects on protein metabolism. In this study the increased water intake was also observed in PCOS rats which were also observed in various previous research trials [6]; but the experimental effect of HT was observed to decrease the water intake in rats [42].…”

Background: Food intake and eating behavior are two important risk factors that lead to obesity and other metabolic and reproductive disorders like polycystic ovarian syndrome (PCOS). Most of the phytonutrients like hydrolysable tannin (HT) have the ability to reduce the nutrient intake that might be a suitable remedy for weight management of females in their reproductive age. Therefore, the present research is aimed to find out the effect of HT on nutrient intake, weekly body weight, weight gain, serum lipids, minerals, immunoglobulins and satiety hormones in PCOS rats.Methods: A total of forty five adult healthy female rats of 56 days old, weighed 135±5g with two consecutive estrous cycles were selected. In order to induce PCOS in rats, the intramuscular injection of 4mg/rat/kg Estradiol- Valerate was used. After induction, a Complete Randomized Design was used to divide the rats into five equal groups (n=9) named as Pc0, Pc0.5, Pc1, Pc1.5 and Pc2. The groups of rats were offered different doses of HT i.e. 0, 0.5, 1, 1.5 and 2% respectively per kg body weight in solution form through oral gavage once in a day for 60 days. Results: After the intake of different levels of HT, the statistical results had shown a significant decrease (p<0.05) in the weekly nutrient intake, body weight, water intake, weight gain, blood glucose in PCOS rats. A similar trend of decrease (p<0.05) was noticed in serum iron, IgM, IgG, leptin, ghrelin, cholesterol, low density lipoprotein and triglycerides while a significant improvement (p<0.05) was also observed in high density lipoprotein in the PCOS rats. However, a non-significant effect (p>0.05) was observed on serum protein and calcium levels.Conclusions: The study concluded that HT had a therapeutical potential to decrease the nutrient intake and its anti-nutritional property could be used as remedy for the management of body weight, hyperglycemia, dyslipidemia and cardiovascular risk factors of PCOS rats.

“…However, the scope of the study did not allow for firm conclusions to be drawn regarding the higher lactose content of colostrum in the CNT cows than in the CON cows; despite this, increases in glucose production could not be excluded (Lin et al, 2016). The increased lactose content that was noted in the colostrum of CNT cows was not supported by findings reported by Jafari et al (2018), who evaluated the effects of oak acorn on the colostrum compositions of goats. This disagreement could be related to differences in methodologies and/or tannin origins and supplementation levels (Jayanegara et al, 2015).…”

This study investigated the effects of dietary supplementation with chestnut tannins (CNT) on metabolic and antioxidant status of prepartum cows along with their colostrum quality. Pregnant multiparous Holstein cows were paired according to parity and body condition score, and assigned either to a diet supplemented with 20 g/d of commercially available product containing chestnut tannins (CNT, n=20) or to an unsupplemented control diet (CON, n=20) for the last 25±2 d of pregnancy. Serum metabolite, insulin and antioxidant capacity indices were measured in blood samples taken at d 25 and d 5 before expected parturition. Chemical composition and IgG concentration were determined in colostrum samples collected from the first milking postpartum. The addition of CNT led to lower BUN (P=0.02) and consequently higher serum glucose (P=0.02) and insulin (P<0.01) concentrations which were associated with lower circulating NEFA (P<0.01) and BHBA (P<0.01) in CNT group than those of CON. The serum paraoxonase 1 (PON 1) activity and total antioxidant capacity (TAOC) were higher at -5 d in CNT than in CON (P<0.01, P=0.03; respectively). Close-up CNT improved lactose percentage and IgG concentration (P=0.03, P=0.04; respectively) and tended to improve percentage of protein and SNF (Solid Not Fat) in primary colostrum (P=0.06, respectively), without affecting colostrum fat and total solid (P=0.98, P=0.43; respectively). Supplementation of CNT in the diet during close-up period did not have adverse effects on metabolic profiles prepartum. Instead, this feeding regimen was more beneficial to antioxidant capacity and colostrum quality than feeding the control diet.

“…The serum protein concentration in rams was 6.06mg/dL on average and this had a tendency (P=0.04) as compared to that of bucks (5.75mg/dL on average).There was a tendency (P=0.07) in bucks fed T4 as compared to bucks fed T2 and rams fed T3 and control diets. The plasma urea concentration is an indicator of protein degradation in the rumen (Jafari et al, 2018), thus the absence of the effect of dietary treatment on serum urea concentration in the current study may be related to the absence of the effect of treatments on CP digestibility coefficient.…”

This study aimed to examine the response of sheep and goats to dietary effects of feeding different levels of oak (Quercus aegilops) acorns in terms of nutrient digestibility, nitrogen balance, rumen function and some serum metabolites. The study was conducted over 4 periods each of 15 days; in each period, rams and bucks were allocated to one of the dietary treatments (control, 5, 10 and 15% oak acorns). Rams and bucks exhibited different responses to the effects of dietary levels of oak acorns. The digestibility coefficient of DM was reduced in both rams and bucks upon feeding acorns, but this decline was significant (P≤0.05) only in rams fed 10 and 15% acorns as compared to rams fed control. Also, the rams and bucks showed numerical decrease in digestibility coefficients of OM, CP, CF, and NPN. The experimental treatments had no effects on nitrogen balance parameters. Bucks exhibited significantly (P≤0.05) higher concentrations of rumen ammonia-nitrogen before, 4 hours and 6 hours after morning feeding. The rumen pH value was significantly (P≤0.05) by the animal species only at the time before morning feeding. The serum metabolites were not affected by the level of acorns in the diet. The results of this study indicate that goats are superior in digesting diets containing oak acorns up to 15%.
