Abstract

This study was conducted to evaluate the success rate of non-penetrative pre slaughter stunning (NPPSS) and the factors that influence it in 460 Australian Brahman cross cattle. Observations were made on the handling of cattle, the implementation of NPPSS, the slaughtering process until the animal was declared dead. The results showed that the stunning success rate of NPPSS (SSR) was 74.35%. Ordinal regression analysis of the six observed parameters, three parameters have a significant influence on SSR: shooting placement area (ASP), shooting placement distance (DSP), and the presence of frontal and nuchal eminence (FE, NE). The ASP at the point of the cross line between two lines from the center of the dorsal eye to the center of the contralateral horn base, DSP at a low position (DSP<3 cm), and presence of FE gave a relatively low of SSR. Thus, it can be concluded that the SSR of the use of NPPSS in Indonesia is relatively low and is influenced by ASP, DSP, and the presence of FE and NE.

Abstract

Terbang pada kelelawar merupakan moda gerak utama karena mereka adalah satu-satunya mamalia yang dapat terbang. Karakteristik morfologi membran sayap diduga berperan penting dalam kemampuan terbangnya. Penelitian ini menganalisis morfologi fungsional membran sayap kelelawar besar (Pteropus vampyrus), dengan fokus pada pengaturan serat elastis dan kolagen. Dalam penelitian ini, kami menggunakan dua kelelawar dewasa yang ditangkap di alam liar dari Jawa Barat, Indonesia. Potongan jaringan membran sayap diwarnai menggunakan pewarnaan hematoksilin-eosin, trikrom Masson, dan Verhoeff-Van Gieson. Membran sayap kelelawar terdiri dari kulit berlapis ganda yang ditutupi oleh lapisan epidermis tipis. Membran sayap terdiri dari serat kolagen dan bundel elastin yang tertata rapi yang disisipkan di antara dua lapisan kulit. Serat kolagen memperkuat membran sayap dengan menahan tekanan udara, sedangkan serat elastis memberikan fleksibilitas pada sayap. Hal ini dapat menggambarkan kekuatan dan fleksibilitas membran sayap kelelawar besar selama terbang.

Abstract

Orangutan is a great ape that has anatomical and physiological aspects similar to those of gorillas and chimpanzees, although orangutan is more arboreal than other great apes. This research aims to study the morphofunctional characteristics of the lower hindlimb and foot muscles of Bornean orangutan and its relation to the type of locomotion and daily behavior. This research was conducted on the right leg of a male orangutan by observing the morphology of the lower hindlimb and foot muscles and observing the behavior of the Bornean orangutan through video observations. The results showed that digital flexor muscles are more developed than plantar flexor muscles as an adaptation towards arboreal activities that require finger flexor movements such as gripping tree branches. Orangutans have rudimentary hallux, which is related by the less developed intrinsic muscle and indicated by the way orangutan grips tree branches dominantly using digits II-V. At a certain time, male Bornean orangutans are active on terrestrial that causes the digital extensor muscles to have more developed as an adaptation to terrestrial activity. It can be concluded the morphology of the lower hindlimb and foot muscles is in accordance to its function and behavior adaptation in arboreal and terrestrial.

Abstract

The study aimed to analyze the dynamics of the development of cortical and medullary cells of adrenal gland in the long-tailed macaque (Macaca fascicularis) during pre- and postnatal period. The samples of adrenal glands were taken from 5 fetuses aged 70, 85, 100, 120, and 150 days of gestation, a newborn aged 10, and an infant aged 105 days old. The samples of the adrenal glands were stained with hematoxylin-eosin and Masson trichrome (Goldners modification). The results showed that the fetal adrenal cortex consisted of a definitive and fetal zones, but in the late gestation (fetus aged 150 days of gestation), the transitional zone appeared between both zones. At the postnatal period, the definitive zone changed to glomerulosa zone, while the outer cells of the transitional zone changed to fasciculata zone which radially arranged. The results indicated that the fetal zone was present until birth and it will disappear gradually after birth. The medullary cells were found at the fetal stages as an irregular structure of small islands of chromaffin cells in the fetal zone. This structure migrated slowly to the center of the adrenal glands. The characteristics of mature chromaffin cells were found in the adrenal glands at postnatal period. In conclusion, the cortex adrenal of the newborn of long-tailed macaque consisted of zona glomerulosa, zona fasciculata, zona transitional, and the remaining fetal zone that has dissapeared gradually after birth.
