Abstract

Carbon dioxide (CO2) and methane (CH4) emission from wetlands significantly contribute to climate change and global warming. The interaction between among vegetation type, various environmental factors, and management regimes such as grazing and mowing is considered important in the calculation of CO2 and CH4 gas flux for an ecosystem. In this study, vegetation composition, CH4 and CO2 flux, soil characteristics, air temperature and humidity from the brackish marsh and salt marsh wetland ecosystems on Terschelling Island in Northern Holland were measured. We aimed to investigate the relationship between vegetation composition, grazing, and mowing on CH4 and CO2 emission. The abundance and number of plant species were higher in brackish than in salt marsh. Grazing was found to influence species richness, 39 species being found in a grazed site of brackish marsh compared to 31 species in a similar ungrazed site. CO2 fluxes in salt and brackish marsh were found to be similar while CH4 flux in the salt marsh was found to be lower than in the brackish marsh. Within the brackish marsh, a higher methane emission was recorded in the grazed zone. However the overall effect of grazing and mowing was found to be negligible for CH4 flux but is suggested to clearly reduce CO2 flux in both the salt and brackish marsh.

Abstract

The aims of this study were to determine the effect of defoliation interval of elephant grass on the growth and production and arranged in Randomized Block Design consisted of 5 blocks and 3 treatments, so there were 15 experimental units. The treatments used were P1 (defoliation 20th day), P2 (defoliation 40th day) and P3 (defoliation 60th day). The finding showed that the responses of the interval defoliation treatments were significantly different (P< 0.05) to the average height of plants and the production of dry matter (DM), where the results of further BNJ tests showed that plant height at treatment P1 (81.78 cm) was different markedly lower than P2 treatment (103.6 cm) and P3 (129.24 cm), as well as different treatment markedly lower P2 from P3 treatment. The production of DM in treatment P1 (1.20 tons/ha) did not differ significantly with treatment P2 (1.94 tons/ha), but significantly higher than the treatment P3 (2.75 tons/ha), while the P2 treatment did not differ significantly by treatment with P1 and P3. The average number of tillers and fresh forage production in treatment P1, P2 and P3 respectively 1.75 tillers and 14.15 tons/ha; 3.44 tillers and 13.07 tons/ha; 4.25 tillers and 1707 tons/ha. Concluded that the longer the interval the higher defoliation of plant growth, additional number of tillers and the higher DM production, while the production of fresh forage is relatively the similar.

Abstract

This experiment was conducted to evaluate the effect of extract of plants containing tannin on invitro CH4 production, fermentation characteristics and nutrient degradability. Six of plant leaves i.e.Gliricidia sepium, Acacia mangium, Leucaena leucocephala, Desmodium intortum, Camellia sinensis,Calliandra calothyrsus and seed of Areca catechu were extracted by using water. Experimentaltreatments consisted of P. purpureophoides (300±5 mg) incubated alone or added with 1.2 mL of plantextracts. The in vitro neutral detergent fibre (NDF) degradability was determined using the first stagetechnique of Tilley and Terry. The results showed that total tannin concentration of plant extract rangedfrom 34 to 95 g/kg DM, and was lowest in D. intortum and highest in A. mangium. Methane productionwas significantly (P<0.001) lower with addition of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus extracts compared to control. Total tannin had a close relationship with CH4production (r=-0.79). There was strong correlation between CH4 production and NDF degradability(r=0.61). It was concluded that water extracts of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus have potential to be used as rumen manipulator in order to reduce CH4 production inruminants.

Abstract The development of beef cattle needs to be supported by regional potential which includes natural resources and human resources. Sorong Regency is one of the areas for beef cattle development in West Papua Province. This research was conducted for three months, from February to April 2021. The study was conducted in four districts that have a high population of beef cattle in Sorong Regency, West Papua Province. namely Salawati District, Segun District, Mayamuk District, and Moisegen. This research was conducted using a survey method with interview techniques and field observations. Breeding experience, education, age have a relationship with the number of livestock kept. The result showed that farmers were in the productive age and had low education. The traditional rearing with extensive system was a common management practice with less than six cows per household. The experience of rearing cattle, age and education had a correlation with number of cows per household (r<0.05). However, there was not very strong relationship with the variable number of beef cattle. The land area factor does not affect the number of livestock and education was not influence management system. It concluded that livestock activity purposed was not up to business level but it was only for saving purposes. Keywords: Beef cattle; Development; Potential; Production; Sorong Abstrak Pengembangan ternak potong perlu didukung oleh potensi wilayah yang mencakup sumberdaya alam dan sumberdaya manusia. Kabupaten Sorong merupakan salah satu wilayah pengembangan ternak potong di Provinsi Papua Barat. Penelitian dilakukan di empat distrik yang memiliki populasi ternak sapi potong yang cukup tinggi di Kabupaten Sorong Provinsi Papua Barat. yaitu Distrik Salawati, Distrik Segun, Distrik Mayamuk, dan Moisegen, pada bulan Februari sampai dengan April 2021. Penelitian ini dilakukan menggunakan metode survei dengan teknik wawancara dan observasi lapangan. Kriteria responden pada penelitian ini adalah memiliki sapi > 3 ekor dan memiliki pengalaman beternak lebih dari 3 tahun. Penentuan jumlah sampel menggunakan rumus Slovin. Hasil penelitian menunjukkan bahwa karakteristik peternak antara lain: berada pada usia produktif, memiliki pendidikan yang cukup rendah, pengalaman beternak yang cukup lama dan tingkat kepemilikan ternak yang rendah. Sistem pemeliharaan ternak bersifat tradisional dengan pemberian pakan dan pengobatan seminimal mungkin. Pengalaman beternak, pendidikan, umur memiliki hubungan dengan jumlah ternak yang dipelihara. Hal ini ditunjukkan dengan nilai koefiesien korelasi r= (r <0.05). Pengalaman beternak dan pendidikan memiliki keeratan hubungan yang tidak terlalu kuat terhadap variabel jumlah ternak sapi potong. Faktor luas lahan tidak mempengaruhi jumlah ternak yang dipelihara. Hal ini dikarenakan sistem pemeliharaan yang dilakukan peternak dominan dengan sistem umbar terbatas dan pemberian pakan ditambah dari sumber lain seperti pinggir jalan dan sumber lain. Faktor luas lahan tidak mempengaruhi jumlah ternak yang dipelihara. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa peternak di sentra peternakan sapi Kabupaten Sorong masih bersifat tradisional yang bertujuan untuk tabungan keluarga dan secara umum belum berorientasi bisnis.

Abstract

Abstrak This study aims to determine the impact of the physiological status of goats with a higher proportion of lamtoro leaves. Forage feed given to goats consisted of a combination of raja grass, Gamal and lamtoro leaves with the following composition: P1= Raja grass 50% + Gamal 50%; P2= Raja grass 40% + Gamal leaf 40% + Lamtoro leaf 20%; P3 = Raja grass 30% + Gamal leaf 30% + Lamtoro leaf 40%. In general, the provision of lamtoro leaves up to 40% of the total ratio did not have a negative impact on the kambing kacang growth and health. The rectal temperature and pulse count in goats were in the normal range for goats, but the respiration rate was twice the normal range. The high frequency of respiration is thought to be due to the high proportion of legumes in the ratio which can increase the amount of feed consumption due to the high palatability of the legumes. This will have an impact on the body's metabolism which is indicated by an increase in respiration. However, the high frequency of respiration in this study can also be caused by environmental factors (temperature and humidty) which were quite high during the study. Keywords: Capra aegragus hircus; Goat; Leucaena leucocephala; Physiologis status. Abstract Penelitian ini bertujuan untuk mengetahui dampak pemberian lamtoro (Leucaena leucocephala) pada status fisiologi ternak kambing kacang. Proporsi daun lamtoro pada pakan ternak kambing diberikan berkisar antara 20-40%. Pemberian lamtoro dikombinasikan dengan pakan hijauan lain dengan komposisi sebagai berikut: P1= Rumput raja 50 % + gamal 50% + lamtor (0%); P2= Rumput raja 40% +daun gamal 40% + daun lamtoro 20%; P3= Rumput raja 30% + daun gamal 30% + daun lamtoro 40%. Secara umum pemberian daun lamtoro hingga 40% dari total ransum tidak memberikan dampak negatif terhadap status fisiologi ternak kambing kacang. Suhu rektal dan jumlah pulsus pada ternak kambing berada pada kisaran normal untuk ternak kambing, namun jumlah respirasi dua kali lipat dari kisaran normal. Tingginya frekwensi respirasi diuga disebagakan tingginya proporsi legum pada ransum yang dapat meningkatkan jumlah konsumsi pakan karena tingginya palatabilitas legum. Hal ini akan berdampak pada metabolisme tubuh yang diindikasikan dengan peningkatan respirasi. Namun demikian tingginya frekwensi respirasi pada penelitian ini dapat juga disebabkan faktor lingkungan (temperature dan kelembaban) yang cukup tinggi semasa penelitian.
