“…The MDA is a final product of lipid peroxidation. Cows in Group H had significantly higher TAC than that in control Group, but there was no significant difference between the groups, which is in accordance with results that an increase in TAC is not parallel with an increase in MDA in cows [ 37 ]. Supplementation of B. papyrifera silage did not affect the serum concentrations of MDA in dairy cows, which might due to the length of the experiment or the dosage of B. papyrifera silage not being in an appropriate range.…”

ObjectiveThis study was carried out to investigate the possible application of Broussonetia papyrifera (B. papyrifera) silage as a functional feeding stuff in dairy cattle.MethodsSeventy-two Holstein cows were divided into four groups randomly and allocated to 6 pens with 3 individuals in each group and fed the original total mixed ratio (TMR) in the dairy farm or the new TMR with 5%, 10%, and 15% B. papyrifera silage, separately. Feed intake were recorded, milk and blood samples were collected, and milk composition, blood metabolites and milk fatty acids composition were measure at the end of the experiment.ResultsDry matter intake of cows decreased when they fed on diet with B. papyrifera, but no differences were observed in body condition score, milk yield, milk protein and lactose, feed efficiency and serum metabolites between groups. Both 10% or 15% of B. papyrifera silage in the diet significantly increased the immunoglobulin A (IgA) and IgG in serum, 15% of B. papyrifera silage increased the content of serum catalase, superoxide dismutase, total antioxidant capacity, and decreased the content of 8-hydroxy-2′-deoxyguanosine. Furthermore, 10% or 15% of B. papyrifera silage resulted in a significant decrease in the milk somatic cell count, and increased the polyunsaturated fatty acids content in the milk.ConclusionThe diets with 10% to 15% of B. papyrifera silage might enhance the immune and antioxidant function of dairy cows and increase the polyunstaturated fatty acid concentration in the milk.

“…MDA is one of the final products of PUFAs peroxidation and accumulates as free radicals increase. In the present study, blood MDA was significantly lower in 15% group than that in control group, 5% group or 10% group, which is consistent with the results that an increase in TAC is not parallel with an increase in MDA in cows [24]. It suggested that some antioxidants in the B. papyrifera silage could reduce the oxidation products or oxidant reaction in animal blood, which might decrease oxidative stress.…”

Objective: The study was conducted to investigate the effects of Broussonetia papyrifera L.(B. papyrifera) silage on growth performance, serum biochemical parameters, meat quality, and meat amino acids and fatty acids compositions in beef cattle.Methods: Sixty-four male Angus beef cattle were assigned to 4 groups with 4 pens in each group and 4 beef cattle in each pen, and fed with the total mixed ration supplemented with 0%, 5%, 10%, or 15% B. papyrifera silage for 100 days (control group, 5% group, 10% group and 15% group) separately.Results: Beef cattle had significantly higher final body weight (BW) in 15% group, higher average daily gain (ADG) and dry matter intake (DMI) in 5% group, 10% group and 15% group, and higher feed conversion ratio (FCR) in 10% group and 15% group. Significantly higher blood superoxide dismutase (SOD) concentration was noted in 15% group, higher blood total antioxidant capacity (TAC) in 10% group and 15% group, lower 8-hydroxydeoxyguanosine (8-OHdG) and malondialdehyde (MDA) in 15% group. Meat had lower pH in 15% group, higher Commission International DeI’Eclairage (CIE) L* in 5% group, 10% group, and 15% group, and lower drip loss in 15% group. Greater concentration of meat polyunsaturated fatty acids (PUFA) was observed in 10% group and 15% group, and docosahexaenoic acid (DHA) in 15% group.Conclusion: Diet with 15% B. papyrifera silage could improve performance and increase final BW, ADG, DMI, and FCR, enhance the antioxidant functions by decreasing blood 8-OHdG and MDA and increasing blood SOD and TAC, improve the meat quality by lowing pH and drip loss and increasing CIE L*, increase the meat PUFA and DHA concentration. Polyphenols and flavonoids might be the main components responsible for the antioxidant activity and anti-biohydrogenation in the B. papyrifera silage. And B. papyrifera silage could be used as a new feedstuff in beef cattle nutrition.

“…In the present investigation, it is observed that multiparous buffaloes have significantly higher oxidative stress indicators than primiparous animals; which was in line with Omidi et al (2017). They found that oxidative stress was significantly lower in the primiparous cows compared to multiparous cows.…”

This experiment was carried out to investigate the effects of parity and body condition score (BCS) pre-calving on oxidative stress indices of 43 milking buffaloes in transition period. The experiment was performed based on completely randomized design with unequal replications, using 3*4 factorial experiments comprising four levels of BCS (2.5-2.99; 3-3.49; 3.5-3.99 and 4-4.5) at two weeks before calving and three groups of parity (1; 2-5 and >5). Blood samples were collected from experimental animals in three stages including: 14 days before parturition, parturition day and 14 days after parturition. The results showed that the serum aspartate transaminase (AST) and alkaline phosphatase (ALP) activities in the highest BCS (4-4.5) group were significantly higher than that of other BCS groups; while the serum gamma-glutamyl transaminase (GGT) activity was decreased with increasing BCS. In addition, blood glutathione peroxidase (GPx) activity and serum malondialdehyde (MDA) content in the lowest level of BCS (2.5-3) were significantly lower than that of other groups. The higher serum catalase activity as well as total antioxidant capacity (TAC) was observed in the BCS of 3.5-3.99. At periparturient period, MDA level and GPx and catalase activities at calving day and alanine aminotransferase (ALT) and AST at 14 days after calving were increased significantly. Moreover, it is observed that multiparous buffaloes have significantly higher oxidative stress indicators than primiparous animals. Based on the results of this study, activity of oxidative stress factors in dairy buffaloes with a higher BSC at parturition significantly increased in 14 days after calving, which indicates an increase in the metabolism of lipids and proteins in these conditions.
