Abstract

In estrous synchronization, the hormone progesterone is an important element. Various hormone preparations currently available have limitations, especially those related to environmental impact issues. Various alternatives are being studied, and using biodegradable polymeric materials (chitosan-polyethylene glycol combination) to develop new devices is considered one of the solutions. This contribution aims to design and evaluate intravaginal implants that can release progesterone and be degraded in the body and the environment. Implants are made by melting and molding techniques. In vitro drug release studies using dyes as drug models. Implant degradation studies tested in compost. Changes in the shape of the implant, while it is in the vagina, are observed by ultrasound. Blood collection was performed three days before and during implantation to obtain a blood progesterone profile. In vitro drug release studies using dye as a drug model showed a chitosan-PEG profile that released the drug faster at first, then slowed down. Implant degradation studies in compost and vagina demonstrated a gradual degradation process. The blood progesterone profile increased during implantation, as high as 15 ng/mL on the third day. In conclusion, the chitosan-PEG intravaginal implant formulation designed using the melting and molding technique proved to be degraded in the compost environment. It released the hormone progesterone for four days according to the degradation period of the implant in the vagina.

Abstract

Ayam broiler adalah jenis ayam yang dipelihara khusus untuk produksi daging yang cepat, sehingga pemeliharaan yang baik sangat penting untuk mencapai performa yang optimal. Kunci pemeliharaan ayam broiler dengan skala produksi adalah pakan, manajemen kandang, manajemen kesehatan, dan faktor eksternal. Perlu dikembangkan cara-cara yang baru dalam pemeliharaan ayam broiler agar menghasilkan kualitas yang baik. Salah satunya adalah dengan mengem-bangkan produk suplemen pendamping pakan. Sebanyak 12.000 ekor ayam DOC dibagi kedalam 2 kelompok yai-tu kelompok kontrol yang diberikan pemeliharaan secara normal. Kelompok berikutnya dalah kelompok EBS yaitu kelompok yang diberikan produk Elektro Bio Stamino® setiap hari didalam air minum dengan dosis 2 mL dalam 1 liter air minum. Pemberian sediaan dilakukan sebanyak 1 kali sehari. Parameter yang diamati meliputi penambahan bobot badan, Feed consumption rate dan Feed intake. Pengambilan data dilakukan selama 31 hari. Hasil penelitian menunjuk-kan kelompok yang diberikan sediaan Elektro Bio Stamino® memiliki performa yang lebih baik dibandingkan dengan kelompok kontrol. Hal ini disebabkan nutrisi dan zat yang terkandung didalam produk mampu melengkapi kebutu-han nutrisi ayam selama masa pemeliharaan. Oleh karena itu pemberian Elektro Bio Stamino® memberikan efek positif terhadap performa ayam broiler.

Abstract

Clitoria ternatea or known as the butterfly pea is widely used in the health sector due to its efficacy as antidiabetic, anti-inflammatory, antimicrobial, anticancer, analgesic, antipyretic, and antioxidants. The purpose of this research is to examine the antioxidants and tyrosinase inhibitor activities of butterfly pea ethanol extract as well as to identify the phytochemical content. Antioxidants activities are determined by the DPPH method. The results of this study indicates that butterfly pea extract has very weak antioxidant activities with an IC50 value more than 200 ppm. The results of the tyrosinase inhibitor activities showed that the butterfly pea extract did not inhibit the tyrosinase enzyme. Based on the screening phytochemical tests, the chemical components contained in butterfly pea extract are flavonoids, tannins, saponins, and steroids. Bunga telang flower extract has very weak antioxidant activity and tyrosinase inhibitor testing showed antioxidant flower extract by DPPH method. Tyrosinase inhibitor assay results showed white Bungatelang extract has no activity to inhibit tyrosinase enzyme.

Abstract

This study was aimed to identify ovarian dynamics using ultrasonography (USG) in simmental crossbreed cows diagnosed prolonged oestrus treatment with human chorionic gonadotrophin (hCG). A total of four Simmental crossbreed cows diagnosed with prolonged oestrous were used in this study. The first oestrous observations in all four cows were a control group, where as the next oestrous cycle observation to the same four cows treated with 1500 IU hCG in jugular vein refer to treated group. The observation of ovarian dynamics was started from the first oestrous day until ovulation occurs in the second oestrus cycle using ultrasonography (USG) with a linear rectal probe. At the same time, follicle and corpus luteum (CL) images were recorded every day. Data were analyzed using paired data comparison test (pair sample t-test). The observation results ovarian dynamics on prolonged oestrus cows showed that the long of oestrous cycle was 22.5 ± 0.5 days, and there are three follicular wave patterns in oestrous cycle. The first wave of dominant follicle was firstly identified on day 3.3 ± 0.5, reached maximum diameter 12.0 ± 0.3 cm. The second and third dominant follicle appeared on day 10.8 ± 0.5 and 15.8 ± 0.5 cm reached maximum diameter 1.2 ± 0.3 cm dan 1.5 ± 0.3 cm. Therapy with hCG does not significantly affect the dominant follicle’s diameter during oestrous (p>0.05). The conclusion of this study showed that 1500 IU of hCG therapy does not affect the development of dominant follicle, however, it can shorten the duration of oestrous and ovulation time.

Abstract

Penelitian ini bertujuan untuk merancang dan mengevaluasi bioavailabilitas implan intravaginal yang terbuat dari poli-ymer kitosan-polietilen glikol (PEG)-polikaprolakton (PCL) yang dapat terbiodegradasi dalam cairan simulasi vagina (SVF) dan vagina sapi. Implan dibuat menggunakan teknik peleburan dan pencetakan dengan 26 formulasi berbeda. Selanjutnya implan direndam dalam 40 mL SVF pada suhu 37,8℃ dan diamati perubahan morfologi implan setiap hari hingga hari ke 5. Implan yang bertahan hingga hari kelima diuji ketersediaannya lebih lanjut pada vagina sapi dan diamati setiap hari selama 2 minggu. Uji perendaman pada hasil SVF menunjukkan bahwa implan dengan kandungan PEG 75-85% lebih cepat meleleh dibandingkan implan dengan kandungan PEG 20-72%. Implan yang mengandung 1-10% PCL terkikis lebih cepat di SVF dibandingkan implan yang mengandung 22-80% PCL. Implan yang mengandung kitosan dapat tetap stabil di SVF lebih lama dibandingkan implan tanpa kitosan. Uji bioavailabilitas pada vagina sapi menunjukkan bahwa implan 21-23 bertahan hingga hari ke 10, sedangkan implan 24-26 dikeluarkan dari vagina sapi selama pengujian. Implan 21-23 merupakan formulasi yang menjanjikan untuk pengembangan implan intravaginal yang dapat terbiodegradasi. Dengan menyesuaikan komposisi kitosan (antara 14-18 berat%), PEG (maksimum 72 berat%), dan PCL (minimal 20 berat%), implan intravaginal mampu meningkatkan ketersediaan hayati cairan vagina dan vagina yang disimulasikan. ternak

Abstract

For several decades, a protocol based on the use of progestagens has been used to manage livestock reproduction with minimal alterations. Recently, researchers have gained insight into the short-term use of progestagen protocols lasting 5-7 days, which has been found to reduce the incidence of vaginitis and obviate the use of antibiotics. Additionally, this approach enables the reutilization of silicone-based devices such as CIDRs after a thorough biosecurity assessment. However, these devices have certain limitations. At the end of the treatment, they must be disposed of and cannot be reused, necessitating a re-evaluation of their use for technical and societal reasons, including animal health and welfare, food safety, and environmental impact.A chitosan-PEG intravaginal implant formulation released progesterone for a period of four days, corresponding to the degradation time of the implant in the vagina. The use of a simple melting and molding process for the combination of PCL-PEG-chitosan implants has been observed to result in degradation of both simulated vaginal fluid and vaginal tissue of cows. The development of intravaginal devices made from biodegradable polymers is considered a potential solution because these materials would degrade within the body, eliminating the need for removal and leaving no residue. These devices are safe for animals and the environment.

Abstract

This research aims to evaluate the protective potency of freeze-dried egg yolk powder on Garut ram sperm during the liquid semen preservation process. Semen with good sperm quality was divided into three groups and diluted using the following Tris diluents: fresh egg yolk-Tris (FEY-Tris), commercial egg yolk powder-Tris (CEY-Tris), and freeze-dried egg yolk powder-Tris (DEY-Tris). Semen that had been diluted was observed every 12 hours until sperm progressive motility was 50%. Sperm quality was tested for progressive motility percentages, viability, intact plasma membrane (IPM), and intact acrosome (IA). Fresh egg yolk had a particle size of 14460.00330.76 nm, with polydispersity index value (PI) and zeta potential (ZP) being 1.000.11 and -9.220.30 mV, respectively. The particle size of commercial egg yolk powder was 877.90168.86 nm with PI value 0.340.04 and ZP-28.71.24 mV. The particle size of freeze-dried egg yolk powder was 1296.0086.73 nm, with PI value 0.700.04 and ZP-34.50.64 mV. Progressive motility percentage showed that DEY-Tris diluent managed to survive to 51.116.06% for 168 hours, compared to FEY-Tris (51.256.74%) which survived for 156 hours, although no longer than CEY-Tris diluent (53.476.33%) which survive for 180 hours (P0.05). Higher sperm motility was also supported by viability percentage, IPM, and IA, which were all higher (P0.05). In conclusion, freeze dried egg yolk powder mixed with Tris buffer was able to maintain sperm quality during the liquid semen preservation process.
