Motile Aeromonas Septicaemia

Motile Aeromonas Septicaemia disease (MAS) attacking tilapia has increased in recent years as a consequence of intensive aquaculture activities, which led to losses in aquaculture industry. The agent causing MAS disease is Aeromonas hydrophila. The disease can be controlled with the β-glucan. As immunostimulants, β-glucans can also increase resistance in farmed tilapia. Studies on the use of β-glucan extracted from baker's yeast Saccharomyces cerevisiae was intended to evaluate the non-specific immune system of tilapia that were challenged with Aeromonas hydrophila. The method used was an experimental method with a completely randomized design consisting of four treatments with three replicats. The dose of β-glucan used as treatments were 0 mg.kg-1 fish (Control), 5 mg.kg-1 fish (B), 10 mg.kg-1 fish (C) and 20 mg.kg-1 fish (D), each treatment as injected three times at intervals of 3 days, the injection volume of 0.5 ml/fish for nine days and resistance surveillance for seven days. The results showed that the difference in the amount of β-glucan and the frequency of the injected real influence on total leukocytes, phagocytic activity and resistance. Total leukocytes, phagocytic activity and resistance to treatment was best achieved by the administration of C a dose of  10 mg.kg-1 of the fish© Penyakit Motil Aeromonas Septicaemia (MAS) yang menyerang ikan nila mengalami peningkatan selama beberapa tahun terakhir sebagai konsekuensi dari kegiatan akuakultur intensif, yang menyebabkan kerugian dalam industri budidaya. Agen utama penyebab penyakit MAS adalah Aeromonas hydrophila. Untuk mengendalikan penyakit tersebut dapat dilakukan dengan pemberian β-glukan. Sebagai imunostimulan, β-glukan juga dapat  meningkatkan resistensi pada ikan nila yang dibudidayakan. Pengkajian mengenai pemanfaatan β-glukan yang diekstrak dari ragi roti Saccharomyces cerevisiae dimaksudkan untuk menguji sistem imun non spesifik ikan nila yang diuji tantang dengan bakteri Aeromonas hydrophila. Metode yang digunakan yaitu metode eksperimen dengan rancangan acak lengkap yang terdiri dari empat perlakuan dan tiga ulangan. Dosis β-glukan  yang digunakan sebagai perlakuan sebesar 0 mg.kg-1 ikan (Kontrol), 5 mg.kg-1 ikan (B), 10 mg.kg-1 ikan (C) dan 20 mg.kg-1 ikan (D), masing-masing perlakuan diinjeksi sebanyak 3 kali dengan interval waktu 3 hari selama 9 hari, volume injeksi 0,5 mL/ekor ikan dan pengamatan resistensi selama tujuh hari. Hasil penelitian menunjukkan perbedaan jumlah β-glukan dan frekuensi pemberian yang diinjeksikan memberikan pengaruh nyata terhadap total leukosit, aktivitas fagositosis dan resistensi. Total leukosit, aktivitas fagositosis dan resistensi terbaik dicapai pada perlakuan C dengan dosis 10 mg.kg-1 ikan©

Two hundred and fifty-five day-old Ross White strain broiler chicks were used to evaluate the Response and economic efficiency of broiler chickens fed graded levels of baker's yeast (saccharomyces cerevisiae) supplement during the harmattan season in the northern guinea savannah zone of Nigeria. There were five treatment groups for both starter and finisher phases. The experiment lasted for eight weeks. Each treatment group had three replicates with 17 birds per replicate and fifty-five birds per group in a completely randomized design (CRD). Treatments 1, 2, 3, 4 and 5 contained 0.0, 0.5, 1.0, 1.5 and 2.0% SC respectively. Results of the starter phase showed significant (P<0.05) differences in terms of final weight gain and feed conversion ratio (FCR). Treatment groups fed the control diet (0.0%), 0.5% and 1% SC had the best final body weight and body weight gain during the starter phase. The FCR was significantly (P<0.05) higher in the treatment group fed 0.5% SC during the starter phase. Mortality was higher (11.76%) in the control group compared to other treatment groups in the starter phase. During the finisher phase, treatment group fed 1.0% SC had significantly (P<0.05) higher final body weight, body weight gain and FCR. Apparent digestibility of crude protein, crude fibre, ether extract, ash, dry matter and nitrogen free extract were better in treatment groups containing SC. The economic efficiency results of this study indicated that the birds fed 1.0% SC were more profitable compared to those fed the control diet. The net profit of the treatment group fed 1.0% SC was N 650.01 compared to the control (N554.35). This study concluded that the optimum inclusion level of Baker's yeast (Saccharomyces cerevisiae) in the diet of broilers starter was 0.5% and 1.0% for finisher diet for improved performance in terms of weight gain and feed conversion ratio (FCR). It is suggested that broiler chicken farmers should be encouraged to include Baker's yeast in the diet of broiler chickens for improved weight productivity and better feed utilization.

The health of farm poultry depends on the balance between normal and potentially pathogenic intestinal microflora. Any changes in this equilibrium are accompanied by functional impairments, which, in turn, lead to a decrease in productivity. The use of probiotics helps to avoid imbalance of intestinal microflora and death of young animals. In this connection, it is relevant to study the effects of probiotic drugs to improve the vitality and immune function of the poultry. The purpose of the research was to clarify the effect of BPS-44 and different amounts of yeast Saccharomyces cerevisiae on the activity of the humoral level of natural resistance in chicken broilers. Experiments were carried out on broiler chicks-308 grown in the Fedyuk M farm in the Zolochiv district of Lviv oblast. The maintenance of the chickens was cellular with free access to feed and water. Technological parameters of broiler cultivation (temperature and light regime) were in accordance with the norms of ONTP-2005. Experiments were conducted in 4 groups of broiler chickens of 100 chicks in each according to the scheme: the control group was fed with the standard feed (SC) according to the existing norms recommended for the ROSS-308 cross; the experimental group I in addition to the SC received a probiotic BPS-44 (registration certificate No. 2154-04-0254-06 dated November 24, 2006), based on the production strain of bacteria Bacillus subtilis ssp. subtilis 44-p, dose 0.21 g/kg, the experimental group II – 1% yeast Saccharomyces cerévisiae; the experimental group III of chickens – 2% yeast Saccharomyces cerévisiae. Blood was taken from chickens in order to carry out immunological research at different age intervals: 11, 27, 34 and 41 days of age. Blood serum was determined by bactericidal and lysozyme activity and the content of circulating immune complexes. The stimulatory effect of BPS-44 and yeast Saccharomyces cerеvisiae in the composition of mixed fodder for broiler chickens on the dynamics of the formation of humoral protection factors in the bird organism was established. At the same time, in the conditions of use of yeast Saccharomyces cerэvisiae in the composition of mixed fodder, a higher level of indices of the humoral level of non-specific resistance was recorded, than the preparation BPS-44.

Peroxidation Processes

The paper studies the influence of feeding broiler chickens in the composition of animal feed preparation BPS–44 and various doses of the yeast Saccharomyces cerevisiae on the intensity of lipid peroxidation (LPO) in terms of vaccination against Gumboro disease.The study was conducted on four groups of chickens at 100 birds each. The control group of chickens fed a standard feed (SC) and a 15–day–old vipoyuvaly vaccine against Gumboro disease (Gumbokal IM Forte SPF). The first experimental group of birds, in addition to the UK received – probiotic BPS–44 (based on Bacillus subtilis strain 44) in an amount of 0.21 g / kg, the second research group – 1% of the yeast Saccharomyces cerevisiae. The third research group of chickens – 2% of the yeast Saccharomyces cerevisiae. For studies using the blood that was taken from the chickens after decapitation at different ages: 11–, 27–, 34– and 41–day–old.It was stated a higher content of intermediate and final products of lipid peroxidation in the blood plasma of broilers in the 27–, 34– and 41–day–old, compared with 11–day, which indicates an increase in the intensity of lipid peroxidation processes and indicates their dependence on age and poultry immunization period . Feeding broiler chickens in the composition of feed yeast Saccharomuces cerevisie and probiotic BPS–44 causes an inhibitory effect on the intensity of lipid peroxidation processes in their body, namely a reduction (p <0,01 – 0,001) content of lipid hydroperoxide and TBA–active products can be detoxication properties associated with study drugs.
