Abstract

Penelitian ini bertujuan mengetahui pengaruh sistem tiga strata terhadap penampilan reproduksi sapi bali. Penelitian dalam bentuk demo plot dengan rancangan acak lengkap terdiri atas 2 sistem peternakan yakni Sistem Tiga Strata (STS) dan Sistem Tradisional (NTS) dengan 5 ulangan. Sistem Tiga Strata adalah tata cara penanaman dan pemangkasan rumput dan legum (sebagai stratum 1), semak (sebagai stratum 2), dan pohon (sebagai stratum 3), sehingga pakan hijauan tersedia sepanjang tahun untuk sapi yang selalu dikandangkan. Sistem tradisional (NTS) adalah pengembalaan sapi waktu siang hari dan pengandangan waktu malam hari dengan pemberian pakan hijauan yang dipotong dari tegalan. Estrus pascapartus dan interval beranak pada sapi STS lebih pendek dibandingkan NTS. Bobot lahir dan bobot sapih pada STS lebih berat daripada NTS, sedangkan lama kebuntingan tidak menunjukkan perbedaan nyata. Penampilan reproduksi sapi bali yang dipelihara dengan sistem pemeliharaan STS lebih baik dibandingkan dengan sistem pemeliharaan NTS.

Abstract

This study aimed to evaluate the effects of ex-situ habitat transfer on physiological and behavioral stress responses in Indo-Pacific bottlenose dolphins (Tursiops aduncus) and to assess the effectiveness of environmental enrichment in mitigating stress and enhancing welfare. Seven dolphins were monitored across four periods: before transfer, immediately upon arrival at the new facility, after 15 days of adaptation, and following 30 days of environmental enrichment using interactive toys. Parameters measured included neutrophil-to-lymphocyte (N/L) ratio, respiratory rate, frequency of stereotypic behaviors, food intake, social interactions, and compliance with trainer commands. The results demonstrated that habitat transfer induced significant increases in N/L ratio and respiratory rate. A 15-day adaptation period was insufficient to restore physiological and behavioral parameters to baseline levels. However, after 30 days of environmental enrichment, stress indicators improved markedly, with decreased N/L ratios, normalized respiratory rates, reduced stereotypic behaviors, and increased food intake, social interactions, and compliance. These findings underscore the importance of integrating structured environmental enrichment strategies into ex-situ conservation and management programs to support optimal welfare in captive dolphins.

Abstract

Berkshire pigs are a popular choice for small and large scale pig farming enterprises worldwide, including in Bali. Berkshire pigs are well known for their superior meat quality and relatively fast growth rate. This study aimed to determine the effect of storage duration on the quality of Berkshire boar spermatozoa diluted with Beltsville Thawing Solution (BTS®) supplemented with melatonin. Semen from Berkshire boars was diluted using BTS® supplemented with melatonin at a concentration of 1.0 mM and stored at a temperature of 15 –20°C. Semen quality was evaluated at different storage intervals: (P1) 48 hours, (P2) 60 hours, and (P3) 72 hours. The observed semen quality parameters included sperm motility, sperm abnormalities, sperm viability, and plasma membrane integrity of spermatozoa, which were examined using smear preparations observed under a microscope. In addition, sperm malondialdehyde (MDA) levels as an indicator of oxidative stress were measured using the Porcine MDA ELISA Kit. Duncan’s multiple range test analysis showed that the storage duration of Berkshire boar semen diluted with BTS® supplemented with melatonin was able to maintain sperm motility, abnormality, viability, plasma membrane integrity, and malondialdehyde levels up to 72 hours of storage, with sperm motility of 40.66%, sperm viability of 53.00%, and sperm abnormalities of 6.33%. These values met the minimum standards set by the Indonesian National Standard (SNI 8034:2023) for liquid boar semen. These results indicate that melatonin acts as an antioxidant capable of neutralizing free radicals, thereby inhibiting the occurrence of oxidative stress in spermatozoa cells.
