Extraction of Uronic Acid From Sargassum crassifolium and Its Feeding Effects On The Eggs Production and Quality of Lohmann Chicken Eggs

ABSTRACTThe use of antibiotics in chicken feed is currently banned because it can cause resistance to pathogenic bacteria and cause residues in products. This study aimed to see the effect of drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium) on the physical and chemical quality of Lohmann chicken eggs. One hundred and twenty laying hens were divided into 2 groups: (1) chickens given commercial feed containing antibiotics and (2) feed without additional antibiotics. The chickens were randomly assigned to one of the 5 brown seaweed supplementation treatments in drinking water A1=0.0% S.crassifolium (control); A2=2.5% S.crassifolium; A3=5.0% S.crassifolium; A4=7.5% S.crassifolium; A5=10.0% S.crassifolium. The study used a completely randomized factorial design of 5 treatments, 2 factors, and 3 replications. Each replication consisted of 6 heads of laying hens. There were no differences between treatments on the performance of laying hens (egg production, egg weight, egg mass, feed conversion); physical quality (eggshell, egg yolk, egg white, shell thickness, egg yolk, Haugh unit, egg index) and chemistry (superoxide dismutase production, thiobarbituric acid reactive substances (TBARS) and Lohmann chicken egg cholesterol) but there was a difference in feed intake. The uronic acid extracted from S. crassifolium has not been able to increase the production and quality of Lohmann chicken eggs.Keywords: lohmann chicken, quality of eggs, Sargassum crassifolium, uronic aci

KARAKTER MORFOLOGI DAN KANDUNGAN NUTRIEN RUMPUT GAJAH DWARF (Pennisetum purpureum cv. mott) PADA NAUNGAN DAN PEMUPUKAN NITROGEN

Penelitian ini bertujuan untuk mengetahuipengaruh naungan dan pemupukan nitrogen terhadap Karakter Morfologi dan Kandungan Nutrien Rumput Gajah Dwarf (Pennisetum purpureumcv. mott). Metode yang digunakan adalah model eksperimental menggunakan rancangan Petak Terbagi (Split-Plot Design) dimana naungan sebagai perlakuan petak utama dan pemupukan nitrogen sebagai perlakuan anak petak. Perlakuan level naungan (naungan 0% dan naungan 70%) dan level pemupukan nitrogen (tanpa pemupukan, pemupukan 92 N/ha, pemupukan 184 N/ha dan pemupukan 368 N/ha) dengan kelompok kemiringan lahan (kemiringan 00,kemiringan lahan 100 dan kemiringan lahan 250). Jumlah keseluruhan satuan percobaan adalah 24 petak. Hasil analisi menunjukkan interkasi naungan dan pemupukan N memberikan hasil yang nyata (P<0.05) terhadap jumlah anakan. Naungan berpengaruh sangat nyata (P<0.01) terhadap jumlah anakan dan kandungan protein, serta berpengaruh nyata (P<0.05) terhadap tinggi tanaman dan kandungan nitrogen. Pemupukan N berpengaruh sangat nyata (P<0.01) terhadap jumlah anakan, tinggi tanaman, kandungan nitrogen dan protein, dan kandungan serat kasar. Interkasi naungan 0% dan pemupukan 368 N/ha menghasilkan jumlah anakan tertinggi yaitu 49,33. Pengaruh naungan 0% tertinggi pada jumlah anakan, sedangkan naungan 70% tertinggi pada tinggi tanaman, kandungan nitrogen dan kandungan protein. Pemupukan N pada pemupukan 368 N/ha menghasilkan jumlah anakan, tinggi tanaman, rasio daun batang, kandungan nitrogen dan protein lebih tinggi dibandingkan perlakuan lain, namun pada kandungan serat kasar tertinggi diperoleh pada perlakuan tanpa pemupukan nitrogen

EFEKTIVITAS PENAMBAHAN TEPUNG TEMULAWAK (Curcuma Xanthorrhiza roxb) dan TEPUNG TEMU PUTIH (Curcuma Zedoaria roxb) DALAM RANSUM KOMERSIAL TERHADAP PERFORMANS AYAM PEDAGING

An experiment was conducted to examine the effectiveness of Curcuma Xanthorrhiza roxb and Curcuma Zedoaria rox flours added in ration on performances of broilers. Fifty-four CP-707® strain broilers were used in the experiment at animal house of Animal Husbandry Faculty, Sam Ratulangi University, Manado and they were placed into cages (60cm x 45cm x 45cm), three birds per cage. Randomized completely design were used in this experiment, with three treatments and six replications. The three treatments were R0 (ration without Curcuma Xanthorrhiza roxb and Curcuma Zedoaria rox flours), R1 (Ration with 2% of Curcuma Xanthorrhiza roxb flour) and R2 (Ration with 2% of Curcuma Zedoaria rox flour). It was found that, there were no significant different (P&gt;0.05) between treatments on feed consumption, body growth and feed conversion ratio of broilers. Feed consumptions were 111,69gram/bird/day (R0), 118,98gram/bird/day (R1), and 124,34gram/bird/day (R2); Body growths were 53,09gram/bird/day (R0), 54,84gram/birdr/day (R1), 57,59gram/bird/day (R2); Feed conversion ratios were 2,20gram/bird/day (R0), 2,18gram/bird/day (R1), and 2,16gram/bird/day (R2) respectively. It was concluded that, the performances of broilers given ration with addition of 2% of Curcuma Xanthorrhiza roxb and Curcuma Zedoaria rox flours were same as the performances of broiler given ration without Curcuma Xanthorrhiza roxb and Curcuma Zedoaria rox flours Curcuma Xanthorrhiza roxb and Curcuma Zedoaria rox flours.

PENGARUH PENGGUNAAN SILASE KULIT PISANG KEPOK (Musa paradisiaca formatypica) SEBAGAI PENGGANTI SEBAGIAN JAGUNG TERHADAP KARKAS DAN VISCERA BROILER

UTILIZATION OF ENSILAGE KEPOK BANANA PEELS REPLACING PART OF CORN IN THE DIET ON CARCASSES AND VISCERA INDICES OF BROILER. The purpose of the present research was to determine the substitution of corn with ensilage kepok banana peels (Musa paradisiaca formatypica) in the diet on  carcasses and viscera indices of broiler. Trial was arranged using an experimental study. Sixty unsexed Cobb day old Chicks (DOC) were used in a Completely Randomized Design arrangement, with 4 treatments and 5 replications. Treatments were formulated as follow: R0 = 50% yellow corn + 0% ensilage kepok banana peels, R1 = 42,5% yellow corn + 7,5% ensilage kepok banana peels, R2 = 35% yellow corn + 15% ensilage kepok banana peels, R3 = 27,5% yellow corn + 22.5% ensilage kepok banana peels. Parameters measured were: carcass weight (g), abdominal fat (%), liver weight (%), and gizzard weight (%). Research results showed that, the subtitution of yellow corn with ensilage kepok banana peels gave a significant different (P0,05) by treatments. It can be concluded that the utilization of ensilage kepok banana peels up to 30% or 15% can still substitute yellow corn in broiler diets.   Keywords : Broiler, Kepok Banana Peels, Carcasses, Viscer

Critical care admission following elective surgery was not associated with survival benefit:prospective analysis of data from 27 countries

Purpose: As global initiatives increase patient access to surgical treatments, there is a need to define optimal levels of perioperative care. Our aim was to describe the relationship between the provision and use of critical care resources and postoperative mortality. Methods: Planned analysis of data collected during an international 7-day cohort study of adults undergoing elective in-patient surgery. We used risk-adjusted mixed-effects logistic regression models to evaluate the association between admission to critical care immediately after surgery and in-hospital mortality. We evaluated hospital-level associations between mortality and critical care admission immediately after surgery, critical care admission to treat life-threatening complications, and hospital provision of critical care beds. We evaluated the effect of national income using interaction tests. Results: 44,814 patients from 474 hospitals in 27 countries were available for analysis. Death was more frequent amongst patients admitted directly to critical care after surgery (critical care: 103/4317 patients [2%], standard ward: 99/39,566 patients [0.3%]; adjusted OR 3.01 [2.10–5.21]; p &lt; 0.001). This association may differ with national income (high income countries OR 2.50 vs. low and middle income countries OR 4.68; p = 0.07). At hospital level, there was no association between mortality and critical care admission directly after surgery (p = 0.26), critical care admission to treat complications (p = 0.33), or provision of critical care beds (p = 0.70). Findings of the hospital-level analyses were not affected by national income status. A sensitivity analysis including only high-risk patients yielded similar findings. Conclusions: We did not identify any survival benefit from critical care admission following surgery
