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. Keywords: Threonine, Saccharomyces cerevisiae, productive performance, broiler, Cobb 500.

This study was to evaluate the effects of supplementation of ethanol extracts of chive (CE) and ginger (GE), and their combination (CG) in diets of broiler chickens on their growth, health performance and economic efficiency. Totally 180 male Egyptian broilers from one-day age were randomly assigned to 6 dietary treatments consisting of 3 replicates of 10 chicks each, of which in the diet of the control group (CT) neither ginger nor chive preparation were introduced, meanwhile the diets of birds in the 5 trial groups (CE1, CE2, GE1, GE2 and CG) were supplemented with 0.5% CE, 1% CE, 0.5% GE, 1% GE and 0.5% CE plus 0.5% GE preparations, respectively. In general, supplementation of CE and GE did not significantly affect feed consumption, mortality, performance efficiency index (PEI), and respiratory syndrome in chickens. However, the herb extract preparations could reduce the incidence of diarrhea in broiler chickens during five to-ten-week age periods. Microscopic examination of small intestinal mucosa showed that the heights of villi and the depths of crypts of chicks in the CE2 treatment as well as the diameters of villi of chicks in the CG treatment were significantly (p < 0.05) higher than in the others. In general, supplementation of 1% CE and the combination of 0.5% CE and 0.5% GE preparations improved the growth performance of broilers, and the combination can be an alternative to antibiotics as growth promoters in feeding chicken.

A total of 100 one-day-old healthy broiler chicks were used to study the effects of lincomycin and bacitracin on some hematobiochemical and immunological parameters. Chicks were divided into four equal groups, 25 each. The first group was kept as control; the 2nd group was received 0.5 g of lincomycin per liter; the 3rd group was received 100 mg bacitracin per liter and the 4th group was administered both lincomycin and bacitracin, each at the above-mentioned dose. Drugs were given in drinking water for 5 successive days from 20th to 25th day of age. Bodyweight was recorded at the beginning of the experiment and at 1st-day post administration where body performance was recorded. One day post administration, blood samples were collected for estimation of hematobiochemical and immunological alterations. The obtained results revealed that broiler chicks administered lincomycin or bacitracin or both revealed a marked increase in bodyweight, weight gain, phagocytic activity, phagocytic index, erythrocytic count, hemoglobin level, packed cell volume, total leukocytic count, serum total protein, albumin, total globulin, α, β and γ globulin. Furthermore, a significant elevation in malondialdehyde associated with a marked reduction in albumin-globulin ratio, serum total lipid, cholesterol and triglyceride and a significant decrease in catalase and superoxide dismutase, were recorded, compared with the control group. In conclusion, lincomycin and bacitracin either alone or in combination have positive impacts on growth performance, immunological and hematobiochemical parameters of broiler chickens. So, it is recommended to use both drugs as growth promoters in broiler chickens.

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.

The effects were investigated of supplementing methionine (Met) in a low-crude protein diet (Low-CP+Met) during Days 11–24 post-hatch and subsequent feeding with a low-metabolisable energy diet (Low-ME; –0.31 MJ/kg) during Days 25–42 on the productive performance and blood chemistry profile of broiler chickens. The 1600 broiler chicks were divided into four groups and fed as follows: (1) Control diet; (2) Low-CP (Met deficiency) diet during Days 11–24, then re-feeding with conventional diet; (3) Low-CP+Met diet during days 11–24, then re-feeding with conventional diet; and (4) Low-CP+Met+Low-ME diet (Low-CP+Met diet during Days 11–24, then re-feeding with Low-ME diet). During Days 11–24, the growth performance of the Control group was better than the other groups (P < 0.01), although the Low-CP+Met diet improved bodyweight, feed conversion ratio and improved the protein conversion ratio compare to the Low-CP group (P < 0.01). During the re-feeding phase (Days 25–42), reducing the dietary energy resulted in better growth performance and a better protein conversion ratio and energy conversion ratio than in the Control group (P < 0.05). Triglyceride, very low-density lipoprotein, low-density lipoprotein-cholesterol and total cholesterol in serum were higher, and non-esterified fatty acid was lower in the Control group than those of the Low-CP+Met+Low-ME group (P < 0.05). In conclusion, reducing dietary protein with balanced amino acids during the grower period and subsequent feeding with a low-energy diet promoted productive performance, improved protein utilisation and reduced fat accumulation via increasing lipolysis and/or disruption of the triglyceride transportation in broiler chickens.

Propolis is a resin produced by bees that has been investigated for its potential to increase the performance of broiler chickens. Therefore, this study aimed to evaluate the inclusion of crude propolis in the diets of broiler chickens from 1 to 21 d of age. A total of 1020 male chicks were distributed in a completely randomized experimental design into six treatments (0, 100, 200, 300, 400 and 500 ppm of crude propolis), with five replications, and 34 birds per experimental unit. The experimental diets were provided from 1 to 21 d of age and subsequently (from 22 to 42 d of age) the birds were fed a nutritionally complete ration based on corn and soybean meal. All supplemented groups showed similar growth performance in all growth phases (P>0.05); however, there was a linear increase in carcass yield at 42 d of age according to increase in crude propolis inclusion from 1 to 21 d of age (P<0.05). At 7 d of age, relative weight of the gizzard increased linearly (P<0.05) with increasing propolis, and at 21 d of age, relative weight of the large intestine showed a quadratic (P<0.05) response, with the lowest value predicted to occur at 278 ppm of crude propolis. The ileum crypt depth at 21 d of age was affected by propolis, with a quadratic response (P<0.05) and highest value estimated at 323 ppm. At 21 d of age, sucrase activity in the jejunum increased linearly with increasing propolis and maltase activity in the ileum showed a quadratic (P<0.05) response, which predicted highest activity at 292 ppm. Amylase activity was lower in animals supplemented with 100 and 400 ppm of propolis at 21 d of age (P<0.05) compared with the control group. Thus, the crude propolis supplementation is not recommended in broiler diets from 1 to 21 d old given that it does not influence the performance, despite small changes in intestinal morphophysiology at 21 d of age.

Effect Of Feeding

This study determined the effect of feeding trough shapes on the growth performance, carcass characteristics and cost benefit analysis of 180 broiler chickens of two strains (90 birds each of Marshal and Hubbard strains) subjected to circular, rectangular and square-shaped 2 feeding troughs with a surface area of 900 cm each. The broiler chicks were brooded for two weeks and thereafter allotted into six treatment groups of 30 chicks each, consisting of 3 replicates of 10 chicks per replicate. Daily weight gains were recorded and at the 8th week, 3 broiler chickens that were of average weights for each replicate were used for carcass evaluation. Data were analysed using PRO GLM at 5% level of significance. Results showed that feeding trough shapes significantly (P< 0.05) influenced the final weight, feed intake and feed conversion ratio. Birds on circular feeding trough recorded the best feed conversion ratio (2.98±0.03). The feeding trough shape and strain did not significantly (P>0.05) affect the cut-up parts and organs measured. In the interaction between strain and feeding trough, the dressing percentage was significantly (P<0.05) affected, but did not follow any trend. Marshal strain on square feeding trough recorded significantly (P<0.05) lowest production cost (N539.25) while Hubbard strain on circular feeder had the highest cost of N605.46. It was concluded that, in terms of cost of production, the square and rectangular shaped feeding troughs could be adopted.

The aim of the study was to examine the possibility of replacing antibiotic growth promoters with a new probiotic preparation. One gram of the preparation contains: 4.7 × 107 of LAB (<i>Lactobacillus casei/paracasei</i> LOCK 0920, <i>L. brevis</i> LOCK 0944, <i>L. plantarum</i> LOCK 0945), 2.0 × 103 of yeast (<i>Saccharomyces cerevisiae</i> LOCK 0140) and a 50 mg of extract from Yucca Schidigera. The experiment was conducted on 99 female broilers divided into three groups consisting of 33 chickens, kept separately. A wheat- and soybean meal-based diet was divided into three parts: A (containing 1 g/kg of probiotic for starter and grower diets and 0.5g/kg for finisher diet), B (containing 14 mg/kg of flavomycin), and C (unsupplemented). The diets were fed from Day 1 to Day 41 of life. Final BW was on average 2.4 kg in all groups, FCR was 1.63 kg feed/kg BWG, neither BWG nor FCR nor mass of the liver, pancreas and gastrointestinal tract were significantly influenced by supplementing the diet with either additive. Special attention should be drawn to the fact that supplementing feeds with a probiotic preparation already after one week of breeding considerably decreased the number of <i>Clostridium</i> bacteria in broilers’ faeces. Nevertheless, it should be emphasized that in this study the excreta of chickens fed with the feed mixed with a probiotic contained the lowest changeability of the number bacteria of the <i>Enterobacteriaceae</i> family and bacteria belonging to coli groups in individual weeks of breeding. It may be concluded that the studied probiotic can be considered as a substitute for antibiotic growth promoters in broiler diets.

A trial was carried out to evaluate the effect of qualitative restriction at different rearing phases on liver fatness and plasma triglycerides without impairing the productive performance of broiler chickens. One hundred and seventy-six male chicks were randomly assigned to four treatments and reared in battery brooders (16 pens with 11 birds each) from 1 to 49-day-old. In the control group, chicks were fed a starter diet (1 to 28-day-old) with 3,300kcal ME/kg of diet and 22.5% CP; grower diet (29 to 42-day-old) 3,300kcal ME/kg of diet and 18.2% CP; and the finisher diet (43 to 49-day-old) 3,300kcal ME/kg and 18.2% CP. Three restrict groups were fed a low 2,800kcal ME/kg of diet and 24% CP from 7 to 14-day-old (treatment 1); from 7 to 21-day-old (treatment 2); and from 22 to 35-day-old (treatment 3). All treatments were fed control diet before and after the feed restriction period. Feed intake was not affected during the feed restriction period; nevertheless, weight gain was lower (P<0.05) for chicks fed restricted diet from 7 to 21 and from 21 to 35-day-old. At the end of each restriction period, scores of liver for fatty infiltration were higher in restricted birds compared to control birds, although no changes were detected in plasma triglyceride levels. On the 49th day of age, less intracellular fatty infiltration was observed in the liver of previously restricted birds compared to control birds, and weight gain was also lower in the restricted groups. Moreover, triglyceride plasma levels were similar among treatments, but decreased in 12-hour-fasted broilers compared to non-fasted birds. The low energy:protein ratio diet affected weight gain and fatty infiltration in the liver, but had no effect on plasma levels of triglycerides.

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.
