“…Data were expressed as means ± SEM This result is similar to the previous study [3] which stated that the percentage of sperm decreased along with the shelf life due to the reduced metabolite energy from spermatozoa leading to an increase in pH ambient which also directly triggered sperm damage [8]. Cryopreservation, which includes storage time and thawing, alters sperm membrane and produces oxidative agents [9]. In vivo, seminal plasma prevents ROS due to the low concentration of cytoplasm in the sperm.…”

Artificial insemination supports the prevention of infectious dispersion in organisms which share the same environment. Meanwhile, spermatozoa usually experience a decrease in quality during processing due to the peroxidation process. This study aims to identify the effect of vitamin E antioxidant addition in goat milk diluent on the quality of thin-tailed sheep semen after storing at 5°C for five days. A total of 4 male thin-tailed sheep were used and the treatments consisted of controls, namely goat milk sperm diluent without vitamin E antioxidant (P0), and others with the addition of vitamin E at a dose of 2 gL-1 diluent (P1); 3 gL-1diluent (P2); and 4 gL-1 (P3). Moreover, the variables observed include individual motility, viability, and intact plasma membrane of spermatozoa after storing at 5°C for five days. The data were analyzed statistically using analysis of variance (ANOVA) with a completely randomized design in one-way. The results showed that the addition of vitamin E antioxidant to goat milk diluent during sperm dilution had a significant effect (P < 0.05) on the motility, viability, and intact plasma membrane. Spermatozoa motility at P0, P1, P2, and P3 were 44.0%, 48.2%, 50.4%, and 53.2%, while the viability was 48.2%, 51.4%, 54.2%, and 56.0%, respectively. Additionally, the intact plasma membranes at P0, P1, P2, and P3 were 41.0%, 46.6%, 48.2%, and 51.4%, respectively. The addition of antioxidant vitamins in goat milk diluent with a concentration of 4 gL-1 produced the best results on sperm quality after cooling. Based on the results, it was concluded that the addition of vitamin E antioxidant to the sperm diluent can improve the quality of thin-tailed sheep chilled semen.

“…No significant differences were observed in weaning weights between male and female animals ( p > 0.05). These results were higher than the 14.02 kg weaning weight reported by Soares et al [ 21 ], for Santa Inês breed animals from single births, weaned at 90 days of age. However, they were similar to the 17.7 kg described by Catto et al [ 22 ] in animals also weaned at 90 days with concentrate supplementation on Brachiaria grass pastures.…”

“…Concentrate supplementation can be an effective strategy to attain these objectives. Soares et al [ 21 ] reported that Santa Inês breed animals from single births, weaned at 90 days and given concentrate supplementation, can achieve gains of 157 g/day. Catto et al [ 22 ] found similar gains of 160 g/day in the same category.…”

Monitoring weight development is essential for decision-making and assessing the effectiveness of management strategies. However, this practice is often hindered by the lack of scales on farms. This study aimed to characterize the weight development and growth curves of male and female Santa Inês lambs from birth to weaning, managed on pasture with creep-fed concentrate supplementation. Data from 212 lambs during the pre-weaning phase were analyzed. The animals were weighed every seven days to evaluate total weight gain and average daily gain. Biometric measurements were taken every 28 days. Mixed models were used to assess the effects of sex and birth type on birth and weaning weights. Simple and multiple linear regression models were employed to estimate live weight using biometric measurements. The non-linear Gompertz model was utilized to describe weight development and formulate growth curves. Results were considered significant at p < 0.05. An interaction effect between birth type and sex (p < 0.05) was noted for birth weight, with the lowest weight observed in twin-birth females (2.96 kg) and the highest in single-birth males (3.73 kg) and females (3.65 kg) (p > 0.05). Birth type significantly influenced average daily gain, total weight gain, and weaning weight (p < 0.05). The Gompertz model accurately depicted the growth curves, effectively describing the weight development. Pearson’s correlation coefficients between biometric measurements and weight were positive and significant (p < 0.05), ranging from 0.599 for hip height to 0.847 for heart girth. Consequently, the simple and multiple regression equations demonstrated high precision in predicting weaning weight. In conclusion, twin-birth lambs receiving concentrate supplementation via creep-feeding and managed on pasture showed different developmental patterns compared to single-birth lambs under the same conditions. The Gompertz model proved effective for monitoring development during the pre-weaning phase. All simple and multiple linear regression models were effective in predicting weaning weight through biometric measurements. However, for practical application, the model incorporating two measurements—body length and abdominal circumference—is recommended.

“…Some problems usually occur in Indonesia are heat stress and feed availability and quality. These problems can lower the sheep's reproductive performances such as a higher score of services per conception (s/c), longer kidding interval, or reduced number of twins or triplet kids [2]. As a consequence of these instances, a research study should indeed increase the capacity of the breeding flock and the reproductive efficiency [3].…”

Cryopreservation of ram sperm reduces sperm motility and breaks sperm membrane integrity due to free radicals developed by reactive oxygen species (ROS). Moreover, it provokes cryodamage and deteriorates sperm quality. This study investigated the effect of glutathione addition as an antioxidant agent on the quality of local ram spermatozoa. The impacts of glutathione additions were observed in five different concentrations (control, 0.5 mM, 1 mM, and 1.5 mM or treatment P0-P4); the extender used to dilute the semen of two rams was andromed diluents. This research examined factors including the quality of fresh sperm, sperm motility, and membrane integrity after chilled. The data in this research was analyzed using one-way ANOVA to determine the effect of glutathione addition between the control and treatment groups. The outcomes demonstrated that adding glutathione significantly (p<0.05) enhanced motility and membrane integrity after stored in cold storage for 48 hours. In comparison with the control, the P1 concentration generated the best results in terms of ensuring the integrity of ram spermatozoa after processing. Glutathione concentration of 0.1mM (P1) showed the best motility and membrane integrity at 0 hours and 48 hours cold storage (82.50 ± 0.92 versus 65.35 ± 1.80% and 87.50 ± 0.50 versus 68.75 ± 1, 83%. In conclusion, the addition of glutathione affected the quality of local sheep spermatozoa after cooling. We obtain the best results of membrane motility and integrity at the glutathione level of 0.1 nM.
