Abstract

This report was aimed to describe the behavioral changes of catfish as observed before two different earthquakes hit the Province of Aceh, Indonesia in year of 2012. A number of 5 African’s catfish (Clarias gariepinus) were placed in an aquarium located in Gapang, Sukakarya Sub-district of Sabang Town, Aceh. Their behavior activities were observed manually at three different times (08.00 AM, 01.00 PM, and 05.00 PM) every day from 1st March up to 11th April 2012. The result of observation showed that the activity of catfish was different between all of them from 1st March 2012 up to morning observation on 11th April 2012. Most of those activities was not showed as very active behavior. However, their behavior was very active in the same pattern when observed at noon and afternoon times on 11 April 2012. On this date, there were two consecutive earthquakes happened at magnitude of >8 Richter Scale at 03.38 PM and 05.43 PM. The epicenter of this earthquake was in Simeulue, with the distance of more and less of 390 km from observation station of catfish in Gapang. It was noted that this abnormal behavior possibly showed as an indication of their ability to detect the increase of pre-seismic activity at 2.38 hours and 43 minutes before the two earthquakes. Perhaps, it is the result of their response to the increase of pre-seismic electromagnetic wave. Further continuous observation and research is needed to ensure the role of African’s catfish (Clarias gariepinus) as abio-sensor for the increase of seismic activity.

Abstract

Cissus quadrangularis Salisb is a medicinal plant which has been used traditionally to cure bone fracture by Acehnese. This study was carried out to investigate the administration effects of Cissus quadrangularis Salisb extract (CQSE) on the histology of lumbar bone in ovarectomized rats. There were 16 female rats (Rattus norvegicus) as samples and were then divided into 4 groups of treatment, with 4 replications each. K0 consisted of ovarectomized rats without CQSE supplementation, whereas K1, K2 and K3 consisted of ovarectomized rats administrated with 300, 500 and 700 mg/kg body weight CQSE for 60 days, respectively. On the day 61st, all rats were euthanized with chloroform and their fourth lumbal bones were collected for histological preparation. Parameters observed were densities of active osteoblast, passive osteoblast and osteoclast. The results of this study showed that density of active osteoblast of rats in K3 (27.25 ± 2.75) was significantly higher (P<0.01) than rats in K0 (1.75 ± 1.25), K1(4.00 ± 1.41), and K2 (8.50 ± 7.40), respectively. There was no significant difference (P>0,05) of passive osteoblast density among rats in K0 (16.50 ± 6.13), K1 (41.00 ± 6.48), K2 (44.50 ± 16.34), and K3 (39.00 ± 15.23). Osteoclast density of rats in K0 (85.25 ± 25.91) was significantly higher (P<0,05) than that of rats in K1 (52.50 ± 16.66), K2 (51.00 ± 7.16), and K3 (50.75 ± 9.20). In conclusion, consecutive administration of 700 mg/kg body weight of CQSE extract for 60 days might increase active osteoblast density in ovarectomized rats.

Abstract

This study aimed to determine the bone growth of broiler chickens fed with additional probiotic Aspergillusniger (AKBIS Prob). The organ taken was the femur bone. A total of 24 broiler chickens reared with additional feed on 4 treatments and 3 repetitions with a combination of additional feed namely P0 (commercial feed), P1 (commercial feed and 2% AKBIS Prob), P2 (commercial feed and 4% AKBIS Prob) and P3 ( commercial feed and 6% AKBIS Prob). The sampling of the femur bone was carried out on chicken 21 and 35 days old and observed histologically after stained with hematoxylin-eosin (HE). The results showed from the examination of macroscopic growth that the femur growth increased more at the age of 35 days compared to the age of 21 days in the treatment group P1, P2 and P3 who were given probiotic Apergillusniger (AKBIS Prob) where the amount of Ca and P required for growth can be fulfilled. On microscopic examination, the measurement parameters were the number of active osteoblasts and osteoblast that looked more passive on the 35th day of treatment, compared to the age of 21 days. While the number of osteoclasts was more at age 21 than at age of 35 days in the treatment group who were given probiotic Aspergillusniger (AKBIS Prob)as additional food.

Abstract

A study has been conducted to investigate the effect of two local herbs in Indonesia; Areca catechu nut and Sauropus androgynous leaf, combined with mineral block to treat gastro intestinal nematode in goats. A.catechu is well known to have anthelmintic property due to its alkaloid and tannin content, and S.androgynus also contains tannin, alkaloid and steroid that will enhance the anthelmintic property of those herbals.  As many as 80 goats had been divided into 4 groups; 20 were treated with albendazole (Group A), 20 were given A.catechu and S.androgynus (Group B), 20 were given combination of A.catechu, S.androgynus, and mineral block (Group C), and 20 as negative control (Group D). The result revealed that herbal treatment showed significantly effective toward nematodes in gastro intestinal, demonstrated by declining egg worm of Group B and C. Body weight improvement and overall performance in Group C was higher compared to other groups. However, goats treated with albendazole showed slightly better results in the decreasing amount of egg worms found after treatment. Nevertheless, A.catechu and S.androgynus are potential anthelmintic herbal; combination with mineral block will enhance the anthelmintic activity. Therefore they are good options for treating helminthiasis in livestock.

Abstract

This study’s purpose is to determine the effect of supplementation of willow bark extract (1000 mg/L) in drinking water and 15% cassava leaf powder in feed on broiler weight gain. This study was designed using completely randomized design (CRD) in which 20 broiler chickens were divided into four treatment groups with five broiler per each treatment. Control group (P0) was only given commercial feed, P1 (commercial feed + cassava leaf powder), P2 (commercial feed + willow bark extract), and P3 (commercial feed + cassava leaf powder and willow bark extract). Data were analyzed using analysis of variance and followed by Duncan test. The results showed that P2 significantly different (P<0.01) compare to P0 and P3, and different (P>0.05) from P1. Group P1 was different (P<0.05) from group P3, but P3 showed no significant different (P>0.05) to P0 on weight gain. whereas feed intake was similar among treatments, however food conversion was differ among treatments. In conclusion, combination of willow bark extract and cassava leaf powder could not increase broiler chickens weight gain.
