The gut of the chicken is a fundamental organ which plays an important role in digestion and host defence. In this study, the gut microbial population as affected by probiotic Saccharomyces cerevisiae (SC) inclusion in broiler chicken diet was investigated. A total of 255 broiler chicks (White Ross breed) were used for this study. The chicks were allocated to five treatment groups in a completely randomized design with each treatment having three replicates of 17 birds each. The experimental diets (T1, T2, T3, T4 and T5) were formulated with varying levels of inclusion of probiotic (SC) T1 served as the control while T2, T3, T4 and T5 had 0.5, 1.0, 1.5 and 2.0% level of inclusion of probiotic (SC), respectively. The parameters taken were the gut content from the jejunum, ileum and caecum which were collected by dissecting the segments. The gut content was then placed in a plane sterile tube and taken to the laboratory for microbial count of Lactose fermenting bacteria (LFB) and non-lactose fermenting bacteria (NLFB). The results from the study showed that there was significant(P<0.05) difference in the population of Lactose fermenting bacteria (LFB) and non-lactose fermenting bacteria (NLFB) in the jejunum, caecum and ileum of the dietary treatment 8 groups. Treatment group fed 0.5% SC had the highest population (9.30x108 cells/ml) of LFB in the jejunum while treatment group fed 1.0% SC had the highest population of 1.73x109 and 1.08x109 cells/mlof LFB in the ceacum and ileum respectively. The population of NLFB was higher in the control group compared to other treatment groups. This study concludes that dietary inclusion of SC in broiler chickens can influence the gut status thereby benefiting the animal through production of digestive enzymes, synthesis of vitamin B and immune stimulation.It is suggested that broiler chicken farmers should be encouraged to include Probiotic (SC) in the diet of broiler chickens for improved gut health.

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 aim of this research was to determine an effect of Newcastle disease virus (NDV) vaccine to histopathologic on Fabricius bursa of broiler chicken at various age levels. Eighteen commercial DOC (Day Old Chick) were divided into 2 groups namely a control group that was given distilled water and a treatment group that was given NDV vaccine namely ND Lasota vaccine ocularly as much one drop per eye at day 3, then a booster dose in drinking water at day 13 was given. The bursa of Fabricius was collected from these chickens on the age of 14 days, 21 days, and 28 days after sacrificing the chickens through necropsied, then histopathological preparations are made using hematoxylin-eosin staining. The parameters observed were measured the number, diameter, and thickness of cortical of lymphoid follicles. Data were analyzed descriptively and quantitatively by unpaired t-test. The results of this research showed the NDV vaccine effects were not significantly different (P0.05) to the number and diameter of lymphoid follicles. In the treatment group, 14 days old broiler chickens had a decreased number of lymphoid follicles, while its diameter tends to grow and the thickness of cortex was also seemed unchanged compared with the control group. Then at the age of 21 days, the number, diameter, and thickness of cortex of lymphoid follicles tend to increase, while at 28 days diameter of lymphoid follicles tend to be slightly reduced, but the number and thickness tend to grow out of control. It was concluded that the NDV vaccine had a good effect on the Fabricius bursa of broiler chickens with increasing age, then histopathological preparations are made using hematoxylin-eosin staining.

Present study was planned to highlight the effects of inclusion of different levels of Saccharomyces Cerevisiae (SC) in broiler feed, on growth performance, hematology and farm economics. One hundred and fifty, one day old broiler chicks (Hubbard) were divided into five groups; each group was subdivided into three replicates of 10 birds each. Starter (CP 20% and ME 2860 Kcal/Kg) and finisher (CP 18.75% and ME 3000 Kcal/Kg) diets were fortified with levels of SC at 0.0, 0.5, 1.0, 1.5 and 2.0 g/Kg to prepare diets A, B, C, D and E respectively. Each dietary treatment was allotted to three replicates. Weight gain, feed consumption and feed conversion ratio improved significantly (p less than 0.05) as a result of feeding diet D containing 1.5 g/Kg SC in comparison to all other treatments. Dietary inclusion of SC significantly (P less tham 0.05) reduced the levels of blood glucose and cholesterol in the birds of all treated groups when compared to those of control group. Maximum reduction in glucose and cholesterol levels was observed in the birds of treatment group D using SC @ 1.5g/Kg diet as compared to those of other treatment groups. Values regarding hemoglobin, PCV and DLC of the birds remained unaffected by dietary inclusion of SC in all treatment groups. However, numerical values of Hb and PCV in the birds consuming diet supplemented with 1.5g/Kg SC were apparently higher than those of control group. The treatment group D using SC @ 1.5g/Kg proved to be cost effective and fetched more profit per kg live weight which positively affected the farm economics.

The soybean aphid Aphis glycines Matsumura (Hemiptera: Aphididae) is a primary pest of soybeans and poses a serious threat to soybean production. Our studies were conducted to understand the effects of different concentrations of insecticides (imidacloprid and thiamethoxam) on A. glycines and provided critical information for its effective management. Here, we found that the mean generation time and adult and total pre-nymphiposition periods of the LC50 imidacloprid- and thiamethoxam-treatment groups were significantly longer than those of the control group, although the adult pre-nymphiposition period in LC30 imidacloprid and thiamethoxam treatment groups was significantly shorter than that of the control group. Additionally, the mean fecundity per female adult, net reproductive rate, intrinsic rate of increase, and finite rate of increase of the LC30 imidacloprid-treatment group were significantly lower than those of the control group and higher than those of the LC50 imidacloprid-treatment group (P < 0.05). Moreover, both insecticides exerted stress effects on A. glycines, and specimens treated with the two insecticides at the LC50 showed a significant decrease in their growth rates relative to those treated with the insecticides at LC30. These results provide a reference for exploring the effects of imidacloprid and thiamethoxam on A. glycines population dynamics in the field and offer insight to agricultural producers on the potential of low-lethal concentrations of insecticides to stimulate insect reproduction during insecticide application.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

This study was conducted in Chimborazo province, Riobamba Canton to evaluate the effect of threonine and the bioactive component of Saccharomyces cerevisiae on the productive performance of the broiler Cobb 500. A total of 270 one-day-old broiler chicken of both sexes were included, which corresponded to an experimental unit size of 15 birds. Two growth promoters were used for the treatments -- T1: Threonine (aminoacid) 200 g/Tn; and T2: bioactive oligosaccharides, obtained from the cell wall of selected strains of S. Cerevisiae (probiotic) 750 g/Tn. These were compared to a control group. The data were analyzed through Analysis of Variance (ADEVA). The separation of means was performed using the Tukey statistic at a level of significance of p < 0.05 and p < 0.01. The data were processed using the Infostat software version 2010. The results showed that the best productive yields were with treatment 2; the values for this treatment were: weight at 28 days: 1369.42 g; weight gain at 28 days: 48.90 g; food conversion at 28 days: 1.39 points; carcass weight: 2527.05 g; and yield to the carcass: 83.85%. Through the economic analysis, it was determined that the highest cost-benefit index was 1.30 USD with the application of T2. So according to the results, a better use of the nutrients that are present in the feed is achieved when bioactive components of S. cerevisiae are supplied in the diet of broiler chickens.
