Abstract

This experiment was conducted to observe the effects of sun-bathing on the Ongole Crossbred cattle’s comfort and performances. Eight heads of 1.5–2 years aged Ongole crossbreed bulls were divided into two groups. All of cattle were white in color. The first group was sun-bathed at 07.00–11.00 am. The second group (control) was raised in the barn whole day. The experiment was held for 90 days. The data collected were environmental conditions (air temperature and humidity, wind speed, and light intensity), physiological conditions, behaviors, feed intake, digestibility, average daily gain and feed conversion. The data was analyzed by student-t test. The result showed that there were no significant differences on humidity, win speed, and light intensity in both places at 07.00–11.00 am. The temperature on the sunbathing place at 09.00 am. was significantly higher (P<0.05) than that in the barn. The pulse rate on the second group was higher (P<0.01) than the first group. There were no significant differences of rectal temperature and respiration frequency on both groups. There were no significant differences behaviors except ruminating duration of the first group was longer (P<0.01). There were no significant differences on feed intake,digestibility, average daily gain, and feed conversion on both groups. It was concluded that sun-bathing gave comfortable environment for cattle, but did not affect on the cattle’s performance.(Key words: Cattle, Sun-bathing, Comfort, Performance)

Abstract

Penelitian dilakukan untuk mengetahui pengaruh konsentrasi formaldehid pada pembuatan undegraded protein (UDP) yang digunakan untuk mensuplementasi pelet pakan lengkap terhadap aktivitas mikrobia rumen secara in vitro. Hasil sisa tanaman pertanian dan hasil samping pengolahannya digunakan untuk menyusun pelet pakan lengkap yang mengandung 12% protein kasar (PK) dan 62% total digestible nutrients (TDN). Cairan rumen untuk percobaan in vitro kecernaan bahan kering (KcBK) dan kecernaan bahan organik (KcBO) dan in vitro produksi gas diambil dari 2 ekor sapi Peranakan Ongole betina umur 2–3 tahun yang difistula pada bagian rumennya. Konsentrasi formaldehid 0; 0,5; 1,0; 1,5; dan 2,0% (volume/berat) digunakan untuk memproteksi bungkil kedelai pada pembuatan UDP, masing-masing adalah K-0, K-0,5, K-1,0, K-1,5, dan K-2,0. Tingkat proteksi bungkil kedelai diuji pada sampel UDP terhadap degradasibahan kering dan organik secara in vitro. Selanjutnya UDP yang paling baik digunakan untuk mensuplementasi pelet pakan lengkap. Aktivitas mikrobia rumen dari berbagai tingkat suplementasi UDP 0; 2,5; 5,0; 7,5; dan 10% bahan kering (berat/berat) pada pelet pakan lengkap berturut-turut adalah S-0, S-2,5, S-5,0, S-7,5, dan S-10,0 diuji secara in vitro produksi gas meliputi: produksi gas, sintesis protein mikrobia, produksi dan proporsi asam lemak volatil. Data hasil penelitian dianalisis variansi menurut Rancangan Acak Lengkap pola searah. Beda antar rerata diuji dengan Duncan’s Multiple Range Test. Hasil penelitian menunjukkan KcBK (%) bungkil kedelai tidak diproteksi K-0 lebih tinggi (P<0,05) dibanding K-0,5, dan K-0,5 lebih tinggi (P<0,05) dibanding K-1,0, K-1,5 dan K-2,0. KcBO bungkil kedelai tidak diproteksi lebih tinggi (P<0,05) dibanding K-0,5, dan K-0,5 lebih tinggi (P<0,05) dibanding K-1,0, K-1,5, dan K-2,0. Perbedaan tingkat suplementasi tidak mempengaruhi produksi gas antar perlakuan pada S-0, S-2,5, S-5,0, S-7,5 danS-10. Sintesis protein mikrobia mg/ml cairan rumen tidak berbeda pada suplementasi UDP S-0, S-2,5, S-5,0, dan S-7,5, namun S-10 lebih rendah (P<0,05) 0,273 mg/ml. Tingkat suplementasi UDP tidak mempengaruhi konsentrasi asam lemak volatil total (mmol). Proporsi asam asetat S-0 lebih rendah (P<0,05) dibanding S-5,0 dan S-7,5, tetapi proporsi asam propionat S-0 lebih tinggi (P<0,05) dibanding S-5,0, S-7,5, dan S-10,0. Dapat disimpulkan bahwa penggunaan formaldehid pada tingkat 1% lebih baik dalam pembuatan UDP. Tingkat suplementasi UDP pada pelet pakan lengkap sampai 7,5% tanpa mempengaruhi aktivitas mikrobia rumen.(Kata kunci: Pelet pakan lengkap, Konsentrasi formaldehid, Undegraded protein, Tingkat suplementasi, Aktivitasmikrobia rumen)

Abstract

This study aims to estimate the carrying capacity of oil palm plantations with the use of herbicides based on the forage availability for Bali cows. The research was performed in palm oil plantation owned by PTPN V Riau, from March 2016 until March 2017. The parameters observed were 1) Forage production that grows between palm trees at 6 weeks cutting age. The forage sample was taken from 5 point of 1x1m2, then subjected to proximate analysis. Data were analyzed with one-way random design, 2) Forage consumption; obtained by observation of 5 pregnant Bali cow and 7 non-pregnant for seven consecutive days 3). Estimated carrying capacity for Bali cows, obtained from the calculation of forage production (/ha/year) divided by forage consumption. The result of the research showed that 1). The production of dry matter (DM) forage in herbicide-treated areas was 689.55 kg/ha/year, not significantly different compared to untreated areas (622.33 kg/ha/year). Crude protein (CP) forage content of forage obtained from herbicide-treated area was significantly higher (p<0.05) than untreated area, whereas the total content of DM and total digestible nutrients (TDN) was not significantly different. DM consumption of pregnant Bali cow was on average 3.68±0.29 kg/head/day or 1,343.20±105.85 kg/head/year and non-pregnant 4.02±0.36 kg/head/day or 1,467.30±131.4 kg/head/year. The estimated carrying capacity on herbicide-treated (0.51 head of pregnant cow/ha), did not show any significant difference compared to untreated area (0.46 head/ha). For non-pregnant, the carrying capacity of herbicide-treated area (0.47 head/ha) was not different with non-treated area (0.42 head/ha). It was concluded that the use of herbicide on palm oil plantation had no effect on the carrying capacity of the Bali cow.

Abstract

This research was aimed to determine the growth, production and prussic acid content of sorghum variety that planted on stylosanthes pasture with different harvesting time. This research was done using split-plot design with three replications which sorghum variety (brown midrib resistance (BMR) and Super-2) as the main plot and harvesting time (6, 8 and 10 weeks) as the sub plot. The sorghum seeds were germinated for 12 days before planted on the 30 days stylosanthes pasture which was planted with planting space 25 x 25 cm. Sorghum was planted with planting space 75 x 25 cm. The variables observed were plants height, dry and organic matter production and prussic acid. Data obtained were analyzed statistically using analysis of variance and significantly different between means were tested with Duncan's New Multiple Range Test  (DMRT). Sorghum BMR had plant height, dry and organic matter production higher (P<0.05) than Super-2. Prussic acid content of BMR was lower (P<0.05) than Super-2. The older harvesting time increase (P<0.05) plant height, dry matter and organic production, but reduced (P<0.05) prussic acid content from 727.34 mg/kg to 241.71 mg/kg. Based on the results it can be concluded that the oldest harvesting time (10 weeks) produced the highest dry and organic matter, and reduce prussic acid content. Sorghum BMR is more productive and grew faster than Super-2. Sorghum BMR that harvested in 10-week shows the best in growth and productivity also had lower prussic acid content.

Abstract

This research was aimed to optimize concentration of phytohormone in callus induction and in vitro regeneration of three species of Brachiaria grass plant, namely Brachiaria brizantha, B. decumbens, and B. ruziziensis. Immature inflorescences were used as explant material. To induce callus, explants were inoculated into Murashige and Skoog (MS) basal medium supplemented with phytohormone combination of 2,4-dichlorophenoxyacetic acid (2,4-D), dicamba and kinetin. Observation of callus induction included percentage of callus formation and callus morphology. The embryogenic calli were then transferred into regeneration media, i.e. MS basal medium supplemented with kinetin and 6-benzylaminopurin (BAP). The result showed that 4 mg/L 2,4-D + 0.2 mg/L kinetin showed highest callus induction in B. brizantha and B. decumbens, namely  76%  and 88% respectively. Whereas in B. ruziziensis, 3 mg/L 2,4-D + 0.2 mg/L kinetin showed highest callus induction, namely 86%. MS medium supplemented with 4 mg/L kinetin showed highest regeneration in all three grass species, namely 92.5% in both B. brizantha and B. ruziziensis, and 88.75% in B. decumbens.

Abstract

This study aims to determine the characteristic morphology and biomass production of Napier grass (Pennisetum purpureum) cultivar Gama Umami under teak tree (Tectona grandis) shade in teak tree forest area of Blora, Central Java. The grass was planted using stem cuttings and maintained for four months using the randomized block design (RBD) method with six repetitions in each treatment. This study consisted of two treatments, namely shade under teak tree stands and non-shade or open area as a control. Maintenance was carried out for 14 weeks with the addition of fertilizers, such as NPK (nitrogen, phosphor, and potassium) and urea. Parameters measured included plant height, leaf length, leaf width, first collar length, number of tiller, and stem diameter. After 14 weeks the plants were harvested, and biomass production data were obtained. The results showed that there were no differences in leaf length, leaf width, first collar length, number shoots, and stem diameter between under the shade and non-shade of teak trees. However, the plant height and biomass production of Napier grass cultivated in non-shade teak trees were higher than under the shade of teak trees. The finding showed that Napier grass cultivar Gama Umami could be cultivated under the shade of teak tree forest and introduce for silvopasture system in teak trees forest area.
