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.

This study aims to assess cholesterol, uric acid and blood glucose levels in laying hens which are fed with the addition of betel leaf juice (Piper Bettle Linn). There were 16 chickens used in layer phase hens. The cage used is an individual cage equipped with a place for feeding and drinking water. The treatments in this study consisted of: (P0) commercial feed + 0 ml of betel leaf juice, (P1) commercial feed + 5 ml of betel leaf juice, (P2) commercial feed + 10 ml of betel leaf juice, and (P3) commercial feed + 15 ml of betel leaf juice. The variables observed were cholesterol, uric acid and blood glucose levels. The data obtained from the research results were analyzed using variance and continued with Duncan's multiple range test. The results showed that the administration of betel leaf juice had no significant effect (p <0.05) on cholesterol, uric acid and blood glucose levels in layer phase hens. Based on the results of the study, it can be concluded that the administration of betel leaf juice does not affect the amount of cholesterol, uric acid, and glucose levels in layer phase hens, but these conditions are still in normal physiological conditions. Keywords: uric acid, layer hens, glucose, cholesterol ABSTRAK Penelitian ini bertujuan untuk mengkaji tentang kadar kolesterol, asam urat dan glukosa darah ayam petelur yang diberi penambahan jus daun sirih (Piper betle Linn) pada level yang berbeda. Ayam yang digunakan sebanyak 16 ekor induk ayam petelur betina fase layer. Kandang yang digunakan yaitu kandang individu yang dilengkapi dengan tempat pakan dan air minum. Perlakuan pada penelitian ini terdiri atas: (P0) pakan basal + 0 ml jus daun sirih,  (P1) pakan basal + 5 ml jus daun sirih,  (P2) pakan basal + 10 ml jus daun sirih, dan (P3) pakan basal + 15 ml jus daun sirih. Variabel yang diamati adalah kadar kolesterol, asam urat, dan glukosa darah. Data yang diperoleh dari hasil penelitian dianalisis menggunakan sidik ragam dan dilanjutkan dengan uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa pemberian jus daun sirih tidak memberikan pengaruh yang nyata (p<0.05) terhdadap kadar kolesterol, asam urat dan glukosa darah ayam petelur fase layer. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian jus daun sirih tidak mempengaruhi jumlah kadar kolestero, asam urat, dan glukosa ayam petelur fase layer, namun kondisi tersebut masih dalam kondisi fisiologis normal. Kata Kunci : asam urat, ayam petelur, glukosa, kolesterol

Beef and chicken meat are potential as a medium for microbial growth such as coliform bacteria since it has a high nutrients content. Coliform bacteria in a given amount could be used as a hygienic indicator and a sign for the presence of pathogenic bacteria. The aimed of this research was to determine the amount of coliform and Escherichia coli on fresh beef and broiler chicken. The bacterial tests included qualitative tests as presumptive test, confirmed test, completed test whereas quantitavely test as Most Probable Number (MPN) to test the number of coliform and faecal coli. The results showed that pH in beef meat is normal and chicken meat shows under normal pH (pH in beef anf chicken meat are  5,7 – 5,98).   Coliform and faecal coli bacteria was detected in 100% of samples had MPN values > 1 MPN/g. It means that the value do not meet eligibility criteria consumption. The high number of Coliform and faecal coli contamination in beef and chicken meat were supposed in relation with market sanitation, cross contamination with other food, low knowledge about hygiene.  Keywords: Number of coliform; Beef and chicken; Traditional market   Abstrak Daging sapi dan ayam memiliki kandungan nutrisi yang tinggi sehingga menjadi media yang baik untuk pertumbuhan mikroba. Salah satu jenis bakteri yang sering mengkontaminasi yaitu coliform dan faecal coli yang merupakan indikator higienis dan sebagai tanda keberadaan bakteri patogen. Penelitian ini bertujuan untuk menghitung jumlah coliform dan faecal coli pada sampel daging sapi dan ayam yang dijual di pasar traditional kota Manokwari menggunakan uji kualitatif yaitu uji presumptive test, confirmed test, completed test sedangkan kuantitatif yaitu Most Probable Number (MPN) untuk menguji jumlah coliform dan faecal coli. Hasil penelitian menunjukkan bahwa nilai pH daging sapi dalam kisaran normal dan pH ayam tergolong rendah yang semuanya pada kisaran 5,7 – 5,98; dan  100% sampel daging sapi, ayam dan pedagang daging terkontaminasi bakteri coliform dan faecal coli dengan nilai MPN yang tidak memenuhi kriteria kelayakan konsumsi, yakni > 1 MPN/g. Tingginya cemaran coliform dan faecal coli pada daging sapi dan ayam terkait dengan faktor kualitas sanitasi pasar, kontaminasi silang dengan bahan makanan lain dan pengetahuan higienitas yang rendah.

Antioxidants are substances that can prevent the occurrence of free radical antioxidation reactions in lipid oxidation.  Red fruit (Pandanus conoideus Lam) is one of the plants endemic to Papua which contain high antioxidant. The aim of this research was to determine the abnormality spermatozoa of ayam Kampung which were received red fruit extract treatment.  Eight cokcs were divided into 4 treatments, each treatment was repeated 5 times. The treatment consisted of control (P0) without extract, P1 with 0.5 mL extract/kgBW/day, P2 with  1 mL extract/kgBW/day and P3 with 1.5 mL extract/kgBW/day. The results showed that red fruit extract decreased the percentage of abnormality spermatozoa (P<0.05) compare to control (without red fruit extract).  Forms of abnormality obtained was abnormalities on the head, namely swelled head, bent head, head detachement, knotted tail and smaller head, middle abnormalities, namely midpiece detachement and bending at midpiece border and abnormalities of the tail, namely bent tail, knotted tail, tail detachement and curled tail.
