Abstract

Abstract. Efforts to control viral and bacterial diseases in poultry broiler should always be done by various efforts. Maintenance of strict management, implementation and administration of vaccines and bio security program are some efforts that are often done by farmers in order to eliminate viral and bacterial diseases. The purpose of this study was to determine the type of pathogenic viruses and bacteria that often infect broiler chickens and how to make efforts to control the broiler chicken farms in the subdistricts of Kedungbanteng and Baturraden, district of Banyumas. The research method was survey on broiler chicken farmers in the areas of Baturraden and Kedungbanteng of Banyumas district. Gradual cluster sampling was used in this study.  11  broiler chicken farms with various breeds were involved.  The current study found that types of bacterial disease that infected broiler chicken farms in the subdistricts of Kedungbanteng and Baturraden were Chronic Respiratory Disease (CRD) and Colibacilosis, whereas viral diseases that infected were the Infectious Bursal Disease (IBD/Gumboro) and New Castle Disease (ND), although the prevalence rate was low. The efforts to control the main virus diseases, IBD and ND, succeeded in pressing the two diseases sould be implemented.Key Words: viral disease, bacterial disease, broiler chicken farmS Hastuti and E Yuwono/Animal Production 13(3):198-206 (2011)

Abstract

Abstract. Menhaden fish oil is commonly used as chicken feed mixture as cheap omega-3 source, plenty and available over the year. Chicken feed containing menhaden fish oil can affect digestion, metabolism and production of meat and egg. The research aimed to evaluate lipid biosynthesis on blood and egg yolk of local chicken fed with feed containing menhaden fish oil as an omega-3 source. The research used 60 hens placed in individual battery cages with four treatments and five repetitions. The treatments were R0 = control/without menhaden fish oil as omega-3 source; R1 = with 2.5%; R2= with 5.0% and R3 = with 7.5% menhaden fish oils respectively. Data analysis used analysis of variance continued with Duncan’s test. The result of the researh showed that the treatments did not signifcantly affect lipid consumption, blood lipid content, blood and yolk cholesterols. However, the treatment significantly affected yolk lipid. The used of menhaden fish oil in feed as an omega-3 source was accumulated in yolk eggs as followed: C18:3 from 0.17% (R0) to 0.29% (R2); DHA (C22:6) from 0.87% (R0) to 3.12% (R3); EPA C18:2 from 1.05% (R0) to 1.85% (R2); EPA C22:4 from 0.77% (R0) to 0.88% (R2) respectively. It could be concluded that enhancement of omega-3 content in egg could be achieved through addition of omega-3 sources in feed.Keywords: egg quality, lipid profile, menhaden fish oilAnimal Production 14(1):6-12, January 2012

Abstract

The aim of this research was to find out the lead concentration in some pigeon tissues in Semarang city. Fifty four pigeons 4-8 weeks old, which collected from 4 locations in Semarang were devided into 4 groups. Group I (15 pigeons) were obtained from the bird markets, group II (15 pigeons) were obtained from who sale fried birds, and group III (14 pigeons) were collected from the bird owners who look after the birds extensively (not in cages), then group IV (10 pigeons) were obtained from the bird owners who look after the birds intensively (in cages). All pigeons were euthanasia by chloroform then necropsied. A part of tissues eg: muscle, lung, liver and kidney were collected for lead examination by using Atomic Absorpsion Spectrophotometer (AAS). The result of the experiment showed that muscle, lung, liver and kidney pigeons were contaminated by lead, and lead concentration of kidney were higher (P< 0.05) than 0,1 ppm. Location of pigeons were not significant (P>0.05) with lead concentration in tissues pigeons. (Animal Production 2(2): 69-74 (2000) Key words : lead, pigeon, Semarang city

Abstract

Coccidiosis is one of parasitic disease caused by Eimeria which is frequently occurs in broiler chick. The disease produces enteritis diarrhea that affects viability and growth.  Stimulating its immune could be done by repeated light oocyst infection.  This research purposed to study infection level and frequency of Eimeria tenella on coccidiosis immunity and broiler performance.   Factorial 2 X 3 was applied with infection level as the first factor: 10.000 oocyst (B1); and 20.000 oocysts (B2). The second factor was infection frequency: once (A1); twice (A2); and three times (A3). The first infection was at 10 days old and the next was 7 days later. Each experiment unit had 8 broilers, and it was replicated 4 times.  On 30 days old, challenge test was conducted by infection using 25.000 oocysts per broiler.  Parameter observed were oocyst elimination, caecum treatment score and clinical symptom post inoculation and post test, weekly body weight, final weight, and feed conversion.  Data were analyzed using variance analysis and Honestly Significant Difference (HSD) test. Weekly body weight and clinical symptom were described.  The result indicated that broiler infected by Eimeria tenella oocyst simultaneously with 20.000 oocysts caused immunization. The number of oocyst did not have significant effect on the performance. (Animal Production 8(1): 72-77 (2006) Key Words : Eimeria tenella, enteritis diareal, performance, immunization.
