Abstract

Efforts to improve the quality of frozen semen of swamp buffalo have always been made, one way is by adding an ingredient that is effective in protecting sperm during the process of dilution, freezing and thawing as a compound that can neutralize free radicals (antioxidant). One antioxidant that has been widely studied is beta carotene (?-Carotene). This natural pigment has the ability to stabilize cell membranes, protect DNA, and reduce oxidative damage to sperm cells. The purpose of this study was to determine the effect of ?-carotene addition in egg yolk Tris diluent on the quality of liquid semen of swamp buffalo. The research materials used consisted of artificial vagina, microscope, Computer Assisted Semen Analysis (CASA), object glass, cover glass, citrate, egg yolk, eosin-nigrosin dye and fresh semen of four-year-old swamp buffalo collected weekly at BIB Tuah Sakato, Payakumbuh. The experimental research method used a completely randomized design with four treatments and five replicates. The treatment of adding ?-Carotene into egg yolk tris (TKT) concentration: 0, 0.1, 0.2, and 0.3% which was equilibrated for 3 hours. Variables observed in this study include mortality, viability and abnormality of liquid semen. The results showed the addition of ?-carotene in egg yolk Tris (TKT) diluent at concentrations of 0%, 0.1%, 0.2%, and 0.3% showed no significant effect on motility, viability, and abnormality of swamp buffalo spermatozoa (P > 0.05). The highest mean motility was recorded at 0.1% concentration (80.12 ± 3.95), followed by 0% (76.54 ± 6.48), 0.2% (76.48 ± 5.59), and 0.3% (73.65 ± 4.88). Viability was also highest at 0.1% (68.22 ± 5.41), then 0% (66.88 ± 6.33), 0.2% (64.94 ± 6.11), and 0.3% (61.51 ± 8.08). The lowest abnormality was found at 0.3% (30.50 ± 4.58), then 0.2% (31.45 ± 2.63), 0.1% (34.23 ± 2.22), and 0% (34.51 ± 2.49). Although not statistically significant, 0.1% concentration produced the highest motility and viability, so it can be considered added in TKT diluent.

Abstract

The increasing demand for animal protein from beef has not been matched by a proportional rise in cattle populations in Indonesia, necessitating strategies such as artificial insemination (AI) to accelerate reproduction. This study aimed to evaluate the success of AI programs in increasing cattle populations in IV Nagari District, Sijunjung Regency, by analyzing Non-Return Rate (NRR), Service per Conception (S/C), and Conception Rate (CR). A survey method was employed using primary data (farmer interviews) and secondary data (Puskeswan medical records from 2019–2023). The results showed NRR ranged from 69.80% to 77.91%, indicating a high pregnancy rate after the first AI, S/C for Bali and Ongole cattle averaged 1.13–1.30, reflecting efficient AI implementation, and CR reached 77.7%, exceeding the national standard (60–70%). In conclusion, the AI program in IV Nagari District successfully increased cattle populations, as evidenced by optimal NRR, S/C, and CR values. This success was influenced by inseminator training, farmer awareness, and AI infrastructure support.

Abstract

Quail are egg-producing poultry known for their highly nutritious eggs and affordable price, making them popular among the general public. However, challenges in quail farming lie in feed efficiency and improving egg quality. One effort to address these challenges is the use of natural feed additives, such as moringa leaves (Moringa oleifera) and bilimbi fruit (Averrhoa bilimbi L.), which have potential as sources of natural antioxidants and bioactive compounds. This study aimed to evaluate the effects of moringa leaf powder supplementation in the feed, combined with bilimbi fruit extract in drinking water, on quail egg quality. The study used 180 female quails (Coturnix coturnix japonica) aged 20 weeks, in a feeding trial using a 2 × 3 factorial completely randomized design (CRD). The treatments consisted of two levels of moringa leaf powder (0% and 3%) and three levels of bilimbi extract (0%, 2.5%, and 5%), with three replications each. Observed parameters included egg weight, egg index, albumen index, yolk index, and Haugh Unit value. The analysis showed no significant interaction between moringa leaf and bilimbi extract supplementation on egg weight and egg index (P>0.05). These findings suggest that moringa leaf inclusion in feed has the potential to improve egg weight, although its effectiveness is influenced by dosage and interaction with other additives.
