Rusiyantono Y, Tanari M, Mumu MI (2011) Conservation of maleo bird (Macrocephalon maleo) through egg hatching modification and ex situ management. . Over exploitation of maleo bird eggs has become the main problem. In addition, habitat demolition and fragmentation have also caused decrease in maleo bird population. This research aimed to know the effectiveness of hatching pattern to produce maleo breeding, studying breeding pattern of maleo bird through hatching approaches of feed quality and temperature adjustment, and studying maleo bird respond towards caring pattern adjustment by measuring plasticity value. There were two phases in this research. The first phase was hatching by using modified incubator. The other one was the caring of the breeding from the result of hatching through feed pattern management using protein and energy balancing. The results of the research indicated that the hatching success was 65%; however, life endurance of the birds from birth to one month of age was only 40%. Their growth showed sufficiently high increase after passing critical period in their body-weight based on feeding pattern containing 21% of protein that was 64.93 g and 62.59 g for maleo in Lore Lindu National Park (LLNP) and Bangkiriang Wildlife Reserve (BWR), respectively. Their monthly body-weight increase was 33.06 g in average of feeding pattern containing 13% of protein for LLNP maleo birds and 36.99 g for the maleo in BWR. It was found that feeding pattern containing higher content of protein (21%) promoted significant increase in the body-weight of maleo birds. Feeding such birds with high protein content feed along with sufficient energy triggered their growth speed. Based on the findings, it was concluded that maleo birds could be preserved by way of hatching, while the birds could be fed with feed containing high protein and energy in order to accelerate their growth after hatching.
Maleo (Macrocephalon maleo) termasuk famili Megapodiidae yang merupakan fauna langka dan endemik Pulau Sulawesi. Keistimewaan jenis burung maleo yaitu memiliki telur lebih besar 4-5 kali dari telur ayam kampung, meskipun besar tubuhnya relatif tidak jauh berbeda dengan jenis ayam, dengan warna kerabang telur mendekati warna merah dadu. Penelitian bertujuan mendapatkan gambaran mengenai perilaku bertelur maleo di Kawasan habitat Kuala Vuno Desa Oloboju Kabupaten Sigi Provinsi Sulawesi Tengah. Penelitian menggunakan metode survey dan dianalisis secara deskripif. Peubah yang diamati yaitu perilaku bertelur sebelum bertelur, saat bertelur dan setelah bertelur. Hasil penelitian menunjukkan bahwa perilaku bertelur maleo di Kawasan Habitat Kuala Vuno Desa Oloboju Kabupaten Sigi Provinsi Sulawesi Tengah dimulai dari maleo mendatangi habitat peneluran, melakukan pengintaian pada lokasi yang dituju, lalu menggali lubang untuk meletakkan telur pada lokasi yang aman. Apabila lubang sudah siap maka maleo betina masuk ke dalam lubang untuk bertelur selama beberapa menit sementara maleo jantan mengawasi selama burung maleo betina dalam proses bertelur. Setelah burung maleo betina keluar dari lubang peneluran maka sepasang burung maleo tersebut menimbun dan meninggalkan habitat penelurannya.
This research was conducted in order to know the conventional feed of tarsier could be substituted by non-conventional feed such as fish and chicken. The research showed that the conventional feed could be susbstituted with fish and chicken without annoying the comfortable of tarsier’s life.
A research was done to study body performance responses of selected Donggala cows to different dietary crude protein content of concentrate feed. Twenty selected Donggala cows with an initial body weights range of 278.6(36.97) kg were used. The animals also had body condition score of 2.63(0.29), body length of 129.85(6.38) cm, shoulder height of 124.8(5.74) cm, bust of 157.45(8.7) cm, and hip width of 37.83(3.4) cm. The animals were arranged in a 4 x 5 randomized block design with 5 dietary treatments differing in crude protein content of concentrate feed (12, 14, 16, 18 or 20 percent). Animals grouping was based on their initial body weights. During the experiment which lasted for 8 weeks, the animals were fed on a ration consisting of 25 percent elephant grass and 75 percent concentrate mix. Results of the experiment indicated that total and daily animals body weight gain, and changes in body condition scores were significantly affected (P<0.01) by the dietary crude protein content of feed. The highest overall and daily body weight gains were obtained at the crude protein level of 18%, while that of changes in body condition score were obtained at the crude protein level of 18%. The dietary crude protein levels did not affect (P > 0.05) animals body dimension measures. It may be concluded that the best dietary protein content of concentrate feed for an optimum body performance in Donggala cows before mating is 18 percent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
