Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh sistem pengawinan dan paritas (beranak ke-) terhadap persentase kebuntingan, litter size dan interval antara penyapihan ke bunting kembali. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap pola Faktorial 2 x 5. Faktor pertama adalah sistem pengawinan (Alami dan IB) dan factor kedua adalah paritas (1, 2, 3, 4 dan 5). Khusus untuk mengetahui interval antara menyapih ke bunting kembali digunakan rataannya dan diuji dengan uji Turkey. Sistem pengawinan berpengaruh nyata (P< 0,05) terhadap laju kebutingan dan litter size lahir hidup dimana pengawinan cara alami (93,23%) lebih baik daripada cara IB (81,64%) dengan litter size lahir hidup masing-masing 10,12 dan 9,26 ekor. Paritas dan interaksinya dengan sistem pengawinan tidak berbeda nyata terhadap laju kebuntingan dan litter size lahir hidup. Interval antara penyapihan ke bunting kembali untuk paritas pertama hingga keempat masing-masing adalah 9,55; 9,08; 7,17; dan 5,64 hari.Kata kunci: sistem pengawinan, paritas, babi.

Abstract

Ultrasonography is a diagnostic method to image the conditions of reproductive organs and it could be supported by vaginal cytology to identify the activities of the ovaries by the types of vaginal exfoliate cells. The aims of this study was to observe reproduction organ through ultrasonography with supportive diagnostic with vaginal cytological assessment. A total of 10 individual queens were used in this study and then grouped into intact group (n=5) and spayed (ovariohysterectomy) group (n=5) based on the anamneses or their medical history. The vagina, cervix, uterus body and horns, and ovaries were imaged and measured by ultrasound. Vagina, uterine body and horn seem as pipe-like structures with hyperechoic outer lines. The lumen in uterine body and horn seem as a hyperechoic structure. The ovaries seem as round- or oval-shaped structures with anechoic follicles. The corpus luteal has thick wall and seen as anechoic in its centre part. The corpus albicans seems as a hyperechoic structure. The vagina of spayed queens seemed more corrugated than those intact queens. The cervix is seen as a hyperechoic structure linking the vagina and uterine body. Exfoliate vaginal epithelial cell types were then also be identified and counted on each queens. The results of vaginal cytology showed that proestrus occured in 3 intact queens, late metestrus in 1 intact and 3 spayed queens, anestrus in 1 spayed queen, and unidentifiable estrus stage in 1 intact and 1 spayed queens. Moreover, the morphology of cervix and uterine was affected by the activity of ovary.

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

Highlight Research The 17β-estradiol hormone induction reduces the percentage of R values in skin and fin color by as much as 50-60%. The 17β-estradiol hormone induction increases total length and body weight, estradiol content, GIS and HIS, and also glucose content. The 17β-estradiol hormone induction shows mature development of the gonadal profile from functional male to functional female. Abstract   As maroon clownfish (Amphiprion biaculeatus) is a protandrous hermaphroditic fish, feminization process with 17β-estradiol hormone can be applied to accelerate the female broodstock candidate supply for further spawning effort. This study aimed to evaluate the feminization of A. biaculeatus with 17β-estradiol hormonal induction. This study used a completely randomized design with several hormone dosage, namely P0 (without 17β-estradiol hormone induction), P1 (0.5 μg 17β-estradiol/g body), P2 (1.0 μg 17β-estradiol/g body), and P3 (1.5 μg 17β-estradiol/g body). These treatments were applied with three replications. Five fish composed of α-fish, β-fish, and three γ-fish were reared in each aquarium for 90 days with a flowing water system. The α- and β-fish were then removed, while the γ-fish was injected with hormone. Otohime pellet feed was fed three times a day until apparent satiation. The results showed that the 17β-estradiol hormone could induce 100% of the feminization process of male A. biaculeatus. The dosage of P3 obtained the lowest value percentage of red, green, blue (RGB), but showing the highest total of length and body weight (6.67±0.42 cm and 6.40±0.78 g, respectively), estradiol content (149.73±4.24 ρg/mL), GSI and HSI (0.38±0.07% and 3.59±0.49%), and glucose content (4.67±0.64 mg/dL), followed by more mature gonad profile than other treatments. This condition indicates that fish in P3 treatment has been reversed as functional female. The average survival rate for the treatment was as high as 60%. Therefore, the application of 17β-estradiol hormonal induction is effective for the feminization process in A. biaculeatus as a protandrous hermaphroditic fish.

Abstract

The aim of this study was to determine the potential effect of milk production based on Most Probability Producing Ability (MPPA) on reproductive performance. The secondary data of body condition score (BCS), reproductive traits and milk production were collected from Baturraden Breeding Center. Identification of FSH sub unit beta Gene polymorphisms were conducted by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. Milk production data was analyzed with formula repeatability (r), heritability (h) and Most Probable Producing Ability (MPPA). The data were also analyzed using correlation and ANOVA (GLM). The results showed that repeatability and heritability of milk production values were 0,84 and 0,4. Gen FSH sub-unit beta was monomorphic fixed to AB genotype and had no effect on the ability of milk production and reproductive performance. BCS values had been affected significantly   on milk production based on grade of MPPA. The correlation analysis showed that the BCS had a sizable effect on milk production with a value of r = 0,68. The relationship between BCS with milk production was expressed in the regression equation MPPA (Kg) = - 59 + 1991 BCS, means the rise of unit will increase milk production of 1991 kg/lactation.
