Abstract

The experiment was conducted to study the effect of stuff feeding given during 22 to 28 days of ages on growth, meat fat and abdominal fat of broiler. Ninety broiler males (J) and 90 broiler females (B) were divided into 6 treatments groups with 3 replications of 10 broiler chickens each. The treatment were control (K) chicken which was fed with commercial diets from DOC to 42 days of age, DJ and P chickens were fed with corn bran (DJ) or pollard (P) from 22 to 28 days and continued with commercial feeding until 42 days. Feeds for DJ and P treatment was supplemented with B-12 mineral. Data collected were body weight, feed consumption, feed conversion, carcass weight, meat as well as abdominal fat. The data were analyzed by analysis split-plot design (3 feed treatments, 2 sex treatments and 3 phases) and then were tested by DMRT. The results showed that the feed treatments (K, DJ, and P) significantly affected (P<0.05) the body weight (1583, 1289, and 1213 g), feed consumption (1180, 1051, and 1035 g), feed conversion (1.67; 2.62; and -1.89), percentage of abdominal fat (1.80, 2.03, and 1.29%). Sex (J and B) significantly influenced (P<0.05) on body weight, feed conversion, percentage of abdominal fat, but feed consumption, percentage of carcass, meat fat, had no significant differences. The interaction of sex and feed showed significant influence (P<0.05) on meat fat at 22 day of ages. The interaction of feed, sex, and phase had significant influence (P<0.05) on body weight and feed consumption. It could be concluded that stuff feeding decreased body weight, feed consumption, percentage of abdominal fat, but increased feed conversion and meat fat.(Key words: Broiler chicken, Sex, Feed stuff, Broiler Starter, Corn bran, Pollard)

Abstract

The research was conducted to evaluate the effect of formalin level and litter addition frequency on the broiler litter characteristics. One hundred and fifty broiler chickens were divided into 10 litter treatment with three replicationand five chickens each. The treatments were combination level of formalin sprayed (0, 4, 8, and 12%) and frequencies of spraying (every 1, 2, and 3 weeks) on to litter (D0F0, D4F1, D4F2, D4F3, D8F1, D8F2, D8F3, D12F1, D12F2 dan D12F3). The data collected were pH, temperature, total bacterial, and ammonia concentration in the litter of broiler chicken. The results showed that level of formalin sprayed (0, 4, 8 and 12%) and frequencies of sprayed (every 1, 2, and 3 weeks)on to litter had not significantly affected litter pH (8.3; 8.7; 8.8; 9.0; 9.0; 9.2; 9.0; 9.0; 9.8 and 9.0) litter ammonia contents (317.1; 475.2; 454.5; 425.3; 218.4; 300.1; 384.0; 375.3 and 417.2 ppm) for (D0F0, D4F1, D4F2, D4F3, D8F1, D8F2, D8F3, D12F1, D12F2 dan D12F3) respectively. Litter temperature had significant differences (33.89; 32.31; 32.83; 32.58; 32.81; 32.81; 32.42; 32.28; 33.28 and 32.72 0C) and total litter of bacteria (1.7X108;1.1X108; 9.9X107; 1.2X108; 7.1X107; 8.5X107; 1.1X108; 4.8X107; 4.8X107; 4.9X107 and 8.2X107 CFU). It is concluded that the formalin sprayed as much as 12% to litter every 1 week (D12F1), produced the best result to reduced littertotal bacteria, but had not decreated the ammonia litter.(Key words: Broiler chicken, Formalin, Litter, Total bacteria, Ammonia)

Abstract

The research was conducted to analyze the effect of seaweed Gracilaria edulis in the diets on the performance of pullet. One hundred and twenty six Lohmann Brown Strain pullets of 14 weeks old were divided into seven seaweed diet treatments. The treatment diets were R0, R1, R2, R3, R4, R5, and R6 contentaining 0.00; 2.50; 5.00; 7.50; 10.00; 12.50 and 15.00 of seaweed, there was three replications, six pullets of each. The collected data were feed consumption, weights and ages of sexual maturity, feed conversion ratio, weight of egg and Iodine content in the egg. The collected data were analyzed by analysis of variance of one way classification, followed by Duncan’s New Multiple Range Test (DMRT). The results showed that the treatments had not significant differences on feed consumption, body weight at sexual matuarity, feed conversion ratio, but significans (P<0.05) on ages at sexual matuarity and egg yolk color (P<0.01). Feed consumption were 80.94 g/chicken/day; 81.02 g/chicken/day; 80.95 g/chicken/day; 81.43 g/chicken/day; 81.69 g/chicken/day; 82.25 g/chicken/day and 82.72 g/chicken/day, body weight at sexual matuarity1898.56 g; 1977.78 g; 1947.78 g; 1947.78 g; 1949.78 g; 1981.67 g; 1949.44 g, FCR 5.78; 5.35; 5.45; 5.08; 5.57; 5.86 and 6.25, egg yolk color 10.23; 11.27; 11. 83; 12.11; 12.44; 12.44 and 12.83 for R0, R1, R2, R3, R4, R5, and R6 respectively. Egg weights were 51.25 g; 54.50 g; 50.89 g; 51.66 g; 51.36 g; 51.36 g and 50.83 g, for R0, R1, R2, R3, R4, R5, and R6 repectively. There had not significant differences on content of egg yolk iodine were 0.47 ppm; 0.48ppm; 0.50 ppm; 0.52 ppm; 0.55 ppm; 0.56 ppm and 0.60 ppm. It was concluded that the use of seaweed Gracilaria edulis until 15.00% in the diet did not decrease the performance of pullet phase and increased egg yolk color, also did not increase iodine in the yolk.(Key words: Seaweed Gracilaria edulis, Diets, Chicken’s work, Pullet phase)

Abstract

Penelitian bertujuan untuk mengetahui pengaruh penggunaan minyak buah merah (MBM) pada pakan terhadap penampilan produksi ayam broiler. Delapan puluh ekor ayam broiler umur sehari (DOC) ditempatkan pada empat kelompok perlakuan pakan yang berbeda, yaitu: P0 (pakan kontrol/tanpa penambahan minyak), P1 (2% MBM), P2 (4% MBM), dan P3 (6% MBM). Setiap kelompok perlakuan terdiri dari empat ulangan masing-masing dengan lima ekor. Ayam broiler dipelihara selama 41 hari. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan analisis variansi pola searah dan diuji lanjut dengan Duncan’s New Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa konsumsi pakan berbeda nyata (P<0,05) dan tertinggi pada P3 (2363,40 g/ekor/6 minggu) diikuti P2 (2350,40 g/ekor/6 minggu), P1 (2181,80 g/ekor/6 minggu), dan P0 (1931,43 g/ekor/6 minggu). Pertambahan bobot badan (P<0,05) tertinggi pada P2 (950,45 g/ekor/6 minggu) diikuti oleh P1 (886,08 g/ekor/6 minggu), P3 (856,00 g/ekor/6 minggu), dan P0 (671,70 g/ekor/6 minggu). Konversi pakan (FCR) menunjukkan hasil yang berbeda tidak nyata pada semua perlakuan. Dari hasil penelitian dapat disimpulkan bahwa penggunaan minyak buah merah dalam pakan mampu meningkatkan konsumsi pakan dan pertambahan bobot badan namun tidak berpengaruh terhadap FCR. (Kata kunci: Ayam broiler, Minyak buah merah, Konsumsi pakan, Pertambahan bobot badan, Konversi pakan)

Abstract

The study was aimed to identify and to analyze the strengths, weaknesses, opportunities and threats that facedthe city of Samarinda in fulfilling the egg need and to formulate the best and suitable strategy for the region to face theshortage of egg supply. The study was conducted in November 2009. The method used in the study was descriptive analysis method. Methods of data collection using questionnaires, interviews, observation and literature study. Methodsof data analysis using the SWOT analysis (strengths, weaknesses, opportunities, threats) were used to identify the internal environmental factors (strengths and weaknesses) and external environmental factors (opportunities and threats) areas. The result was then drawn in the quadrant analysis of SWOT and interpreted in the SWOT matrix could be to show the position and direction of regional development as well as alternative strategies that can be run. The results showed that internal identified value was 0.3922 and the external identified value was 0.0308. Development strategy at Samarinda in the first quadrant with a strengths was greater than the opportunities, so the region must be able to use these strengths to take advantage of existing opportunities. The area should implement an aggressive growth strategy (growth oriented strategy) in order to meet the self need of eggs in the region Samarinda.(Key word: Layer, Development strategy, SWOT analysis)
