This study was carried out to explore the adding effect of alcoholic extract of Ferula hermonis Boiss roots and some antioxidants to Tris extender on post-cryopreserved sperm's cell individual motility and live sperm percentages of Holstein bulls for different preservation periods (cooling at 5°C, 2, 30 and 60 days post cryopreservation, PC). Eight Holstein bulls of 2.5-3 years of age were used in this study. Semen was collected via artificial vagina in one ejaculate per bull per week for the 7-week experimental period. Pooled semen was equally divided into eight treatments using Tris extender. The alcoholic extract of Ferula hermonis Boiss roots (0.03 ml/ 50 ml extender; T2), L-Carnitine (0.06g/ 50 ml extender; T3), reduced glutathione (0.03 g/ 50 ml extender; T4), vitamin C (0.2 g/ 50 ml extender; T5), L-Carnitine; 0.06g/ 50 ml extender + alcoholic extract of Ferula hermonis Boiss roots; 0.03 ml/ 50 ml extender (T6), reduced glutathione; 0.03 g/ 50 ml extender + alcoholic extract of Ferula hermonis Boiss roots; 0.03 ml / 50 ml extender (T7) and vitamin C; 0.2 g/ 50 ml extender + alcoholic extract of Ferula hermonis Boiss roots; 0.03 ml/ 50 ml extender (T8) were added to Tris extender and comparisons in response were made with the control group (Tris extender, A1). The total phenolic compound of the extract was 124.38 ± 5.05 mg GAE/ g extract and the extract with 0.01 and 0.03% did not hemolyze the red blood cells and had not poisoning effect on blood cells. The T2 group exhibited higher (P≤0.05) sperm's cells individual motility and live sperm percentage as compared with the T1 group at all preservation periods. On the other hand, T3 group was significantly (P≤0.05) exhibited greater percentages of sperm's cells individual motility and live sperms percentages in comparison with the T1 group at all preservation periods. In conclusion, the adding of alcoholic extract of Ferula hermonis Boiss roots (0.03 ml/ 50 ml extender) and L-Carnitine (0.06g/ 50 ml extender) to Tris extender had an obvious influence in enhancing the sperm's cell individual motility and live sperm percentages of Holstein bulls at different cooling and cryopreservation periods as compared with the control (T1) group. This may contribute to a positive enhancement in conception and pregnancy rates of the inseminated cows, and consequently increase the owner's economic income.

In this study, the effect of a combination of vitamin C, vitamin E and selenium on ethanol-induced duodenal mucosal damage in rats was investigated morphologi-cally and biochemically. The duodenal mucosal injury was produced by oral administration of 1 mL of absolute ethanol to each rat. Animals received vitamin C (250 mg/kg), vitamin E (250 mg/kg) and selenium (0.5 mg/kg) for 3 days and absolute ethanol 1 hour after last antioxidant administration and were sacrificed 1 hour after absolute ethanol. Extreme degeneration in intestinal mucosa of rats given ethanol was observed morphologically. In addition, an increase in neuronal nitric oxide synthase immunoreactive areas was observed in the rats of the group given ethanol. On the other hand, a normal morphological appearance and a decrease in neuronal nitric oxide synthase immunoreactive areas were detected in the rats given ethanol+vitamin C+vitamin E+selenium. In the group to which ethanol was administered, an increase in serum cholesterol and a decrease in serum albumin levels were determined. On the other hand, in the group to which ethanol+vitamin C+vitamin E+selenium were administered, serum cholesterol value decreased, and the serum albumin level increased. As a result, we can say that the combination of vitamin C, vitamin E and selenium has a protective effect on ethanolinduced duodenal mucosal injury.

Cryoprotective Solution

Background: The addition of antioxidant substances to a cryoprotective solution can increase its protective capacity, shielding spermatozoa from the oxidative stress caused by the seminal cryopreservation process. However, there is no record of a seminal cryopreservation protocol of tambaqui (Colossoma macropomum) using antioxidants as a supplement to the cryoprotective solution. Thus, the objective of this study was to evaluate the effects of adding vitamin C, vitamin E, cysteine, and/or taurine to the seminal cryopreservation of tambaqui.Materials, Methods & Results: Pools of semen (n = 10) were diluted in cryoprotective solutions supplemented with: vitamin C (T1), vitamin E (T2), vitamin C + vitamin E (T3), cysteine (T4), taurine (T5), and taurine + cysteine (T6). The control treatment (T7) was not supplemented. Diluted semen was loaded in 0.5 mL straws, frozen in a dry-shipper, stored in a cryogenic cylinder, and then thawed in a water bath (45ºC for eight seconds). The quality of fresh and cryopreserved semen was evaluated by measuring total motility, progressive motility, curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity, and straightness using a computerized system of sperm analysis. Sperm membrane integrity parameters were analyzed using eosin-nigrosin staining, sperm morphology was assessed using pink bengal staining, and motility duration was measured by a digital timer. Data were analyzed using the statistical program SAS (2002) and the results were expressed as means ± standard error of the mean. The results showed that, in general, there was no significant increase in seminal quality when antioxidants were added to the cryoprotective solution. The T5 treatment promoted an increase (P < 0.05) in progressive motility when compared to T1 (6.33 ± 1.14% and 2.98 ± 0.88%, respectively). However, it did not differ significantly (P > 0.05) from the other treatments. Treatments T2 and T5 presented the highest values of VCL (34.74 ± 2.58 and 33.60 ± 1.81 μm.s-1, respectively). These were higher (P < 0.05) than T1 (26.31 ± 1.64 μm.s-1) but not different (P > 0.05) from the T7 control (30.87 ± 1.49 μm.s-1). The VSL and VAP results showed that T1 presented the lowest velocity (9.89 ± 1.75 and 15.06 ± 1.92 μm.s-1, respectively) compared to the other treatments (P < 0.05) that did not differ from each other. Combining the two vitamins (T3) or the two amino acids (T6) was not advantageous in relation to the use of only one of these antioxidants.Discussion: The present study reports, for the first time, results of the addition of antioxidants to the tambaqui seminal freezing medium. The addition of taurine and vitamin E, although not significantly different from the control treatment, resulted in a tendency to increase sperm kinetics. This effect may be due to the action of taurine as a regulator of Ca2+ transporters, which is necessary to trigger sperm activation, and to the ability of vitamin E to scavenge reactive oxygen species produced during lipid peroxidation. On the other hand, the reduced sperm quality observed when vitamin C was used may have been related to the toxicity caused by a high concentration of this vitamin. In addition, once the safe dose of antioxidants has been exceeded, the normal physiological functions of reactive oxygen species can be inhibited. Thus, it is concluded that the use of vitamin E and taurine promotes promising results of curvilinear velocity after thawing of sperm. Therefore, these treatments are recommended, as well as more tests to determine their optimal concentrations.

This study was aimed to explore the effect of adding pentoxifylline (PTX) and nitric oxide (NO) to Tris extender on some post-cryopreserved semen attributes of Holstein bulls for different preservation periods (cooling at 5◦C, 48 hrs., 1, 2 and 3 months post cryopreservation, PC). Seven Holstein bulls of 2.5-3 years old were used in the current study during the period from 20th November, 2017 to 20th August, 2018. Pooled semen was equally divided into three groups within one experiment. PTX (0.192 g / 100 ml extender) and NO (0.018 g / 100 ml extender) were added to Tris extender and comparisons in response were made with the control group (Tris extender, C). The PTX group exhibited greater (P≤ 0.01) sperm's cell individual motility percentage as compared with the C group at cooling (5ºc) and 48 hr PC periods, while, PTX and NO groups were superior in these percentages at the remaining PC periods than C group. Excluding data of 2 months PC, greater (P≤ 0.01) live sperm percentage was observed in PTX and NO groups in comparison with the C group at all preservation periods. Lesser (P≤ 0.01) abnormal sperm percentage were noticed for PTX and NO groups as compared with the C group at all preservation time periods. The PTX and NO groups exhibited greater   (P≤ 0.01) acrosome and plasma membrane integrity percentages in comparison with the C group at all preservation time periods. In conclusion, adding PTX and NO to Tris extender enhanced some of  PC semen characteristics of Holstein bulls at different preservation periods.

This study was conducted to investigate the effect of swim-up and glass wool as sperm separation techniques with adding vitamin E and superoxide dismutase (SOD) to Tris extender on improving some post-cryopreserved semen quality for Holstein bulls. Low and good of semen were extended using Tris extender. Good semen quality (GSQ) was divided into 3 groups (L1; Tris extender, L2; 2 mM vitamin E, L3; 200 IU SOD) Low semen quality (LSQ) was divided into two main groups, and subdivided into 3 sub-groups (L4; Tris extender, L5; 2 mM vitamin E, L6; 200 IU SOD). In the second main group, swim-up and glass wool techniques were used with adding vitamin E and SOD and subdivided into 3 sub-groups with each technique, and referred to L7, L8 and L9 for swim-up technique and L10, L11 and L12 for glass wool technique. Improving sperms’ cell motility and live sperm and reducing total sperms’ abnormalities percentages of low semen quality were noticed using swim-up and glass wool techniques were used with adding vitamin E and SOD.  In conclusion, glass wool filtration separates out dead, abnormal and immotile sperm cells, a good sperm harvested by this technique.

Cubing machines in food processing have evolved over the years, which have made products like Star®, Knorr®, and Chicken® bouillon cubes become commercially available today, even in many parts of Africa. On the other hand, the fermented mesquite seed “okpeye” food condiment, traditionally produced by well-trained artisans and widely utilised in Nigeria, requires further product development in order to compete with bouillon cubes. Quality comparisons between the cubed “okpeye” condiment and commercially available bouillon cube products have not yet been reported. Therefore, cubing fabrication/costing and machine performance on African fermented “okpeye” condiment quality attributes, compared with commercial bouillon types, were done. The processing of mesquite seeds into the “okpeye” condiment resembled those of artisans. Bouillon cube products involved the Star®, Knorr®, and Chicken® types. Quality attributes involved proximate, micronutrient, phytochemical, and microbial aspects. Results showed that the throughput capacity of a cubing machine increased with an efficiency of 48 condiment cubes/min, forming properly without separation. Across all studied samples, the protein, ash, moisture, crude fat, crude fibre, and carbohydrate contents were in the range of 1.45–42.50%, 5.29–6.75%, 8.50–12.29%, 2.56–18.54%, 2.45–3.19%, and 18.16–25.56%, respectively. The protein, fat, moisture, calcium, iron, magnesium, and manganese contents of “okpeye” condiment were significantly higher (p < 0.05) than those of bouillon cubes. Fair amounts of vitamins B1, B2, B3, and E were found, with the “okpeye” condiment higher in vitamin E. Besides the flavonoids (0.12–0.18%), alkaloids (0.08–0.15%), saponins (0.19–0.55%), and tannins (0.69–0.93%) present, the microbial loads were similar (p > 0.05) across all samples. Indeed, the “okpeye” condiment can be cubed, and by quality attribute, it competes favourably, and very promising substitute to commercial bouillon cubes.
