“…The decrease in sperm viability of frozen semen of Limousin bull was due to an increase in the number of damaged and dead sperm during the cryopreservation process and the formation of lactic acid in the diluent medium. The decreased sperm viability in egg yolkbased diluents can also be attributed to the higher calcium ions in the egg yolks, which can cause acrosomal damage (Coppock, 2019). Nagata et al (2019) reported that a satisfactory value for post-thaw sperm viability for the success of AI is >55%.…”

Diluents are substances added to the semen to increase the semen volume, reduce sperm density, and maintain sperm viability. This study aimed to compare the effects of various semen diluents on the quality of frozen semen of Limousin bull. Three mature Limousin bulls were used as semen sources. The semen was collected using an artificial vagina and then evaluated for its quality. Sperms with motility less than 70% and abnormality greater than 20% were excluded from this study. After semen evaluation, each ejaculate was individually divided into four equal tubes and diluted with skimmed milk-egg yolk (SMEY), Tris-egg yolk (TEY), Tris-egg yolk-skimmed milk (TEYSM), or Andromed ® . Diluted semen was loaded into a mini straw and then equilibrated at 5 °C for 4 h. Following equilibration, the straws were frozen. The percentages of sperm motility, viability, intact membrane, and sperm DNA integrity were evaluated after freezing. Furthermore, malondialdehyde (MDA) and aspartate aminotransferase (AST) enzyme concentrations were assessed after thawing. The sperm motility with TEY, TEYSM, and Andromed ® did not differ significantly but was higher than with SMEY. Sperm viability, membrane intactness, and sperm DNA integrity did not differ among treatments. By contrast, the MDA levels and concentration of AST in the Andromed ® diluent semen showed the lowest values compared with SMEY semen (p<0.05) but did not differ from those of TEY and TEYSM semen. To conclude, TEY, TEYSM, and Andromed ® diluents performed equally well, and although they showed better results than SMEY, sperm diluted in SMEY are still suitable for artificial insemination.

“…The reproductive process leads to dynamic changes in metabolism and energy consumption, which may be the reason for the excessive production of free radicals (oxidants) formed during the physiological process of oxygen consumption [16]. The antioxidant effects of some nutraceuticals during the reproductive cycle with the high oxidative stress improve the reproductive function and reduce infections and other diseases of the genitourinary system [17]. In their studies, Johansson and Waller noted that the vitamin status in the blood and milk of the cows in organic dairy production could satisfy the needs for Vitamins A and E without adding synthetic vitamins, except for the calving period when the needs are high [18].…”

The use of carotene-containing preparation in cows for the prevention of postpartum complications

et al. 2021

Background and Aim: It is known that metabolic disturbances in the animal body negatively affect parturition, uterine involution, and, ultimately, fertility, especially in cows, during the first insemination. Although the method of diet optimization with the use of a software package results in positive outcomes, adjustment is required for certain groups of animals (e.g., cows), in accordance with the period of the year. Every year, in the spring and autumn, blood is taken from animals to detect metabolic disorders, and then either the diet is balanced or, if the cows lack vitamins and minerals, they are administered to cows parenterally or with food. The aim of this study was to assess the efficiency of using carotene-containing preparation in the prevention of postpartum complications in cows. Materials and Methods: Before the start of the experiment, blood was collected from the animals of the experimental and control groups, with ten animals in each group, and its serum was examined for the presence of carotene. Low carotene content was found in the serum of all animals (from 0.2 to 0.25 mg%) with the norm within the range of 0.40-0.62 mg%. The cows of the experimental group were injected subcutaneously with the carotene-containing preparation 30, 20, and 10 days before the expected calving date at a dose of 10 mL per head. The carotene-containing preparation was a solution of crystalline β-carotene substance in deodorized sunflower oil. Moreover, the share of β-carotene was at least 0.18%. The drug was administered intramuscularly into the rump. Results: In the postpartum period, the retention of the placenta was observed in two animals of the control group. The uterine involution in the cows of the control group was 16.0 (p<0.05) days longer than that in the cows of the experimental group. The duration of placenta separation in the cows of the control group was on average 3.21 h longer (p<0.01) than that in the cows of the experimental group. The period from calving to the introduction of the embryo was 63.17±1.56 days in the control group and 48.3±0.83 days in the experimental group. The survival rate of embryos in the cows of the experimental group was 60%, and the period from the calving date to the introduction of the embryo averaged 48 days, which were 14.9 (p<0.05) days less than that in the cows of the control group. Conclusion: When the carotene-containing preparation was administered in a dose of 10 mL subcutaneously to cows 30, 20, and 10 days before the calving date, the blood carotene content increased, and the duration of the last stage and uterine involution decreased. The period from the calving date to the introduction of the embryo was reduced to 48.3±0.83 days, and the survival rate of embryos was 60%.
