There are conflicting reports in the literature of the possible role of the ureides, allantoin and allantoic acid, in the nitrogen economy of Arachis species. Therefore, xylem sap composition in food peanut (Arachis hypogaea L.), and two forage peanuts (A. pintoi L. and A. glabrata Benth.) has been studied in detail. Xylem saps were collected from peanuts grown under different nutritional regimes and environmental conditions in the glasshouse and field in Australia, Malaysia and Indonesia, and the N‐containing solutes analysed. The relative amounts and concentrations of ureides in these peanut exudates were compared with those of soybean (Glycine max [L.] Merr.) – a species known to export ureides in its xylem stream as the major product of N2 fixation. Xylem concentrations of ureides in soybean were high in N2‐fixing plants (2.9 to 3.7 μmol ml−1), representing 60 to 88% of xylem solute nitrogen, but it contributed only 9% (0.7 μmol ml−1) if plants were unnodulated and supplied nitrate. In all species of peanut, concentrations of ureides measured in xylem sap were generally much smaller (0.02 to 0.37 μmol ml−1; 1–7% of xylem nitrogen) and were unaffected by peanut species or cultivar, rhizobial strain, plant size, growth rate, or stage of development, and were not related to N2 fixation (less than 0.1% of currently fixed nitrogen exported as ureides) or the assimilation of nitrate. Apparently high levels of ureides in sap from some field‐grown plants were shown to be due to interference with the ureide colorimetric assay by some contaminating compound rather than represent increased ureides per se.
Penelitian ini bertujuan untuk mengetahui indeks performan, tingkat mortalitas, pencapaian bobot badan dan feed convertion ratio yang dicapai oleh peternak yang menggunakan closed house system dan open house system. Hasil penelitian menunjukkan bahwa tingkat mortalitas pada peternak open house system lebih baik dibanding dengan closed house system. Bobot Badan ayam pedaging pada closed house system lebih tinggi dibanding dengan open house system pada umur rata-rata umur panen 32 hari. Feed Convertion Ratio (FCR) pada peternakan closed house system lebih baik bila dibandingkan dengan open house system. Indeks performan pada peternakan dengan closed house system lebih tinggi bila dibanding dengan open house system, namun keduanya termasuk dalam kategori sangat baik.
1991. Re-evaluation ofthe role of ureides in the xylem transport of nitrogen in Arachis species. -Fhysiol. Plant. 83: 560-567.There are conflicting reports in the literature of the possible role of the ureides, allantoin and allantoic add, in the nitrogen economy of Arachis species. Therefore, xylem sap composition in food peanut {Arachis hypogaea'h.), and two forage peanuts (A. pintoi L. and A. glabrata Benth.) has been studied in detail. Xylem saps were collected from peanuts grown under different nutritional regimes and environmental conditions in the glasshouse and field in Australia, Malaysia and Indonesia, and the N-containing solutes analysed. The relative amounts and concentrations of ureides in these peanut exudates were compared with those of soybean (Glycine max [L.] Merr.) -a species known to export ureides in its xylem stream as the major product of N2 fixation. Xylem concentrations of ureides in soybean were high in N2-fixing plants (2.9 to 3.7 ixmol mL'), representing 60 to 88% of xylem solute nitrogen, but it contributed only 9% (0.7 |imol ml"') if plants were unnodulated and supplied nitrate. In all species of peanut, concentrations of ureides measured in xylem sap were generally much smaller (0.02 to 0.37 nmol mL'; 1-7% of xylem nitrogen) and were unaffected by peanut species or cultivar, rhizobial strain, plant size, growth rate, or stage of development, and were not related to N, fixation (less than 0.1% of currently fixed nitrogen exported as areides) or the assimilation of nitrate. Apparently high levels of ureides in sap from some field-grown plants were shown to be due to interference with the ureide colorimetric assay by some contaminating compound rather than represent increased ureides per se.
The activity was carried out to determine the health status of qurban animals and the worthiness of the qurban meat during eid al-Adha in Manokwari Regency through antemortem and postmortem examinations along with the application of health protocols during the Covid-19 pandemic. Six hundred fifty-six beef cattle were examined. The antemortem examination includes the observation of the general condition, eye mucosa, anus, and fecal matter. The liver and rumen were examined through direct observation (inspection) of the presence of worm parasites. Covid-19 health protocol observations were carried out on butchers, meat officers, and the facilities around the activity. The data were analyzed descriptively and presented in percentages and figures. The average Body Condition Score (BCS) of the cattle was 3 to 4. The locomotion and skin turgor was normal. In general, the examined meat was fit for consumption. The eye mucosa color in the examined cows was pink. The anus condition of all the cows examined is clean and the stool consistency is soft. A total of 106 livers (16.16%) had fasciolosis and 89 rumens (13.57%) were positively infested with Paramphistomum sp. Most of the slaughter places have implemented health protocols with body temperature checks, washing their hands when entering the slaughtering area and most of the workers have to wear a mask. Keywords: Qurban Animals; Heartworms; Covid-19 ABSTRAK Kegiatan ini bertujuan untuk mengetahui status kesehatan hewan kurban dan kelayakan daging kurban di Kabupaten Manokwari melalui pemeriksaan antemortem dan postmortem dan penerapan protokol kesehatan selama wabah covid-19. Hewan yang diperiksa adalah sapi dengan jumlah sebanyak 656 ekor. Pemeriksaan terdiri atas ante-mortem meliputi pemeriksaan keadaan umum, mukosa mata, anus dan feses dengan cara inspeksi dan pemeriksaan post-mortem, meliputi: hati dan rumen yang dilakukan dengan pengamatan langsung (inspeksi) keberadaan parasit cacing dalam organ periksa. Pengamatan protokol kesehatan covid-19 dilakukan pada: petugas jagal, petugas daging, petugas jeroan dan fasilitas disekitar kegiatan berlangsung. Data dianalisis secara deskriptif dan disajikan dalam persen dan gambar. Rerata Body Condition Score (BCS) sapi yang disembelih adalah 3 sampai 4. Lokomosi 100% dan turgor kulit normal. Secara umum daging yang diperiksa layak dikonsumsi. Rerata warna mukosa mata pada sapi yang diperiksa adalah merah muda. Keadaan anus dari seluruh sapi yang diperiksa adalah bersih dan konsistensi fesesnya lunak. Sebanyak 106 organ hati sapi (16,16%) yang diperiksa mengalami fasciolosis dan sebanyak 89 rumen (13,57%) positif terinfestasi Paramphistomum sp. Sebagian besar tempat penyembelihan telah melakukan protokol kesehatan berupa pemeriksaan suhu tubuh, wajib cuci tangan saat memasuki area penyembelihan dan sebagian besar petugas jagal, petugas daging dan petugas jeroan telah mengenakan masker. Kata Kunci: Hewan Kurban; Cacing Hati; Covid-19
