<p>Una estrategia para mejorar la salud del tracto gastrointestinal en pollos de engorde es incluir productos novedosos como los aditivos funcionales entre los que se encuentran las levaduras, caracterizadas por su papel beneficioso en la salud animal. En este estudio se evaluó el valor nutricional de tres cepas nativas de levaduras, aisladas de frutales de Colombia. Se utilizaron 240 pollos machos para evaluar los efectos de levaduras en el desempeño, calidad de la canal, parámetros hematológicos y del corazón. Los pollos se distribuyeron al azar en seis tratamientos: tres diferentes levaduras nativas (0,5% inclusión en la dieta), dos controles positivos (inclusión de dos levaduras comerciales) y un grupo control negativo sin levaduras. Las aves que fueron alimentadas con las levaduras comerciales presentaron menor consumo de alimento total (-73,7 g) comparado con los grupos a los que se les suministró levaduras nativas. Por consiguiente, el peso corporal final fue más alto para los grupos de levaduras nativas comparado con las levaduras comerciales (98,9 g/ave, <em>p </em>&lt; 0,01). Los pollos alimentados con levaduras presentaron mejor conversión comparados con el grupo control. El peso de la canal y la pechuga fueron más altos para los grupos alimentados con levaduras (<em>p </em>&lt; 0,05). Se concluye que las levaduras nativas pueden tener un efecto beneficioso en el desempeño de pollos de engorde, y algunas levaduras nativas podrían mejorar las características de calidad de carne como la terneza. Aunque se requiere mayor investigación, pueden considerarse las levaduras nativas como aditivos funcionales prometedores para los pollos de engorde.  </p><p> </p><p><strong>Evaluation of three native Colombian yeasts as feed additives for broilers</strong>  </p><p>A strategy to improve the health of the gastrointestinal tract in broilers is to include novel products such as functional feed additives. Among these, yeasts have been recently reported to play a beneficial role as a feed additive. The objective of this study was to evaluate the nutritional value of three strains of yeasts, isolated from native fruits in Colombia. A total of 240 male broilers were used, and the effects of yeasts on performance, carcass quality, blood and heart parameters were evaluated. Chicks were randomly distributed in six treatments: three different native yeasts (0.5% of inclusion in the diet), two positive controls added with commercial yeasts and a negative control group without yeasts. Chicks fed with yeasts commercial had lower total feed intake (-73.7 g) compared with the native yeast groups. Therefore, final body weight was higher for the native yeast groups compared with the commercial yeasts (98.9 g/bird, <em>p </em>&lt; 0.01). Chicks fed native yeasts tended to have better feed conversion ratio (intake/gain) compared with the control group. Carcass and breast weights were higher for the yeasts groups (<em>p </em>&lt; 0.05). It is concluded that native yeasts can have a beneficial effect on broiler performance, and some native yeasts could also improve meat quality traits such as shear force. Although more research is required, native yeasts should be regarded as relevant and promising functional additives for broilers. </p>

In this study 120 piglets were allotted to 3 dietary treatments, negative control group, one group receiving a blend of essential oils (EO) derived from oregano, anise and citrus peels (40 mg/kg diet), and a positive control group treated with avilamycin as growth promoting feed additive (40 mg/kg diet). On day 22 of the experiment, 12 representative animals from each treatment group were sacrificed and tissue samples were collected for quantitative real time-PCR analysis and gut tissue morphology. EO and avilamycin decreased the gene expression of the transcriptional factor NFκB and the apoptotic marker TNFα significantly in the ileum and jejunum, respectively. The expression of the proliferation marker Cyclin D1 was also significantly decreased by both substances in the colon, mesenteric lymph nodes and spleen. The colonic crypt depth was reduced by avilamycin, and also numerically by the essential oils. These changes correlated with the up-regulation of the apoptosis factor Caspase 3. Histomorphometry revealed a smaller size of ileal Peyer’s patches through the use of both feed additives, which correlated significantly with lower expression rates of NFκB. In conclusion, the results suggest that EO and avilamycin relieved weaning piglets from an immune defence stress in a similar way.

The main purpose of this study was to explore the effects of Spirulina (Spirulina platensis) as a feed supplement by replacing Vitamin-Mineral Premix on the performance of broiler. The study explored that final body weight was 1039, 1070, 1044, 1065, 1117 and 893 g/bird in group 1, 2, 3, 4, 5 and 6 where significantly (p<0.5) higher weight observed in Spirulina group (5) but lower in negative control group (6). Feed intake observed more or less similar in all groups (1483±24g; p>0.5). Feed conversion ratio (kg FI/kg LWG) observed significantly different like 1.72, 1.65, 1.69, 1.62, 1.61 and 1.99 in group 1, 2, 3, 4, 5 and 6 respectively (p<0.5) where higher in negative group (6) and control group (1), but is lowest and similar in 75% Spirulina group (4) and highest (100%) Spirulina group (5). %Ash of different dietary groups were 46.35, 46.54, 48.93, 49.93, 55.07 and 46.92 of group 1, 2, 3, 4, 5 and 6 respectively. The %ash of bone was gradually increased among dietary groups and the best result was obtained in 100% Spirulina group 5 (55.07). It also revealed that diets containing no vitamin-mineral premix with 100% Spirulina improve the performance of broiler. The findings suggest that poultry farmer can use spirulina as a feed item for broiler for more yield.

This study was conducted to determine the effect of phytogenic feed additive and prebiotic on vegetable protein base diet in broiler performance.  A total of 90 chicks (Cobb-500) were weighted and randomly assigned to the three treatment groups (To, T1 and T2) and supplemented with either phytogenic feed additives or prebiotic and reared for 28 days. Data on live body weight, body weight gain, feed intake and feed conversion (FC) were taken at weekly interval. Results revealed that significant (P<0.05) increase in live body weight of broilers was evident in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group at 4th weeks of age. No significant (P>0.05) differences were found in live weight gain among the treatment groups on weekly intervals along the whole experimental period. However, significant differences (P<0.05) were evident on cumulative weight gain at 3rd and 4th weeks of age. In case of feed intake at the age of 3rd and 4th weeks, significant (P<0.05) differences were obtained with decreased feed intake in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group. In case of feed conversion (FC), there were significant (P<0.05) differences among the groups on 1st week and 4th week of age. Best FC was accounted for prebiotic supplemented group along the whole experimental period. The survivability rates were 96.67%, 100% and 100% in control group, phytogenic feed additive and prebiotic supplemented group respectively. Results finally showed that vegetable protein when supplemented with phytogenic prebiotic feed additives and prebiotic c an additive beneficial effect on performance of when compared to non-supplemented control diet. So, ration using vegetable protein mixed with phytogenic feed additives or prebiotic can be recommended for broiler.Progressive Agriculture 28 (4): 323-330, 2017

This study evaluated the effect of ginger on the growth performance, carcass quality of broiler chickens. 20 broiler chickens were randomly selected into two treatment groups identified as T1 and T2 with a positive control and a negative control group. Each treatment contained with five birds. Birds on T1 were treated with 1% ginger extract and T2 was treated with 2% ginger extract via drinking water. Significant variations (p<0.05) existed between the control and other treatments in mean final body weight, dressed weight, daily feed intake and feed conversion ratio. At the end of experiment (35th day) for 1% ginger extraction treatment the live body weight is 1746gm (p<0.05), dressing weight 1106.4 (p<0.05) and FCR is 1.67(p<0.05). The usage of the test ingredients had a significant effect (p<0.05) on dressing percentage. Supplementation of ginger improves the performance of broilers when added at the rate of 1% of broiler ration and can be a possible alternative to antibiotic growth promoter in the feeding of broiler chicken.Asian J.

Abstract There is limited information on performance and gut microbiota balance response to alternatives to antibiotics growth promoters on broiler at high altitude and level of health challenge. Therefore, Two experiments were conducted to evaluate the effects of alternatives to antibiotics supplementation on broiler performance and health at 2500 m.a.s.l. In, Exp. 1, a total of 1080 day-old Cobb-500 male broilers were used in a completely randomized block design. Eight experimental diets containing 1) Negative Control (NC), 2) Bacitracin methylene Disalicylate at 55 mg/kg (BMD), 3) Direct fed microbial at 750 mg/kg (DFM) 2x1011 CFU/kg of lactic acid bacteria, 4) a blend of essential oils (150 mg/kg; EO), 5) combination of permeabilizers, organic acids and phytochemicals (0.1%, CN), 6) DFM+EO, 7) DFM+CN, and 8) EO +CN. Performance was evaluated through the feeding period of 42 d with a new litter. There were no significant differences in performance nor mortality rate during the whole feeding period. In, Exp. 2, 1232 one-day-old Cobb-500 male chicks were randomly divided into 56 experimental units and exposed to similar treatments as described on Exp. 1. Performance variables, and cecal-microbiota population were evaluated during 42-d with a re-used litter. Overall, daily gain was increased for BMD, DFM, and EO+CN compared to NC (P &lt; 0.05). Feed intake was not altered by dietary treatment (P = 0.892). Feed conversion rate was improved by BMD and EO compared to NC (P &lt; 0.05). Total coliform, and E. coli population was increased by DFM and CN compared to NC (P &lt; 0.005). Total Enterobacteriacea was not altered by dietary treatment with exception of EO, that increased its population compared to remaining treatments (P &lt; 0.001). Data form this experiments suggest that positive effect of organic feed additive supplementation, especially EO, depend on bird health challenge at high altitudes.

Feed of commercial broiler fortified by the external sources of vitamin and minerals which is expensive and increase the cost of feed. Blue green algae (Spirulinaplatensis) would be an alternative to those synthetic micronutrients after production in laboratory scale was studied in broiler.Spirulinaplatensiswas cultured in inorganic media contained macronutrients NaHCO3, K2HPO4, NaNO3, K2SO4, NaCl, MgSO4.7H2O, CaCl2, and FeSO4.2H2O and micronutrient solution containing H3BO4, MnCl2.4H2O, ZnSO4.7H2O, CuSO4.5H2O, MoO3, CoCl2.6H2O. Media was autoclaved and Spirulinawas cultured for 12 hours lighting with continuous aeration for 15 days to use in poultry feed. Day old broiler chick (180) was reared offering starter mash diet for 7 days. Birds were divided into 6 groups having 30 birds in each (10 per cage). Birds were offered 1. Control diet, 2. 75% premix+25% Spirulina, 3. 50% premix+50% Spirulina, 4. 25% premix+75% Spirulina, 5. 0% premix+100% Spirulina and 6. 0% premix+0% Spirulina (negative control). Spirulinawas calculated on DM basis added minerals in the media. After 21 days (28 day old) final body weight was 1039, 1070, 1044, 1065, 1117 and 893 g/bird in group 1, 2, 3, 4, 5 and 6 where higher (P<0.5) weight observed in Spirulinagroup (5). Feed intake was observed more or less similar in all groups (1483±24g). Feed conversion ratio was 1.72, 1.65, 1.69, 1.62, 1.61 and 1.99 in group 1, 2, 3, 4, 5 and 6 respectively (P<0.5) where higher in negative control group (6) and control group (1), but was lowest in 75% Spirulinagroup (4) and highest (100%) Spirulina group (5). Ash% is also highest in 100% Spirulina group 5 (55.07) than any other group. Considering growth performance of broiler, complete replacement of vitamin-mineral premix could be possible by cultured Spirulinaalong with media in broiler diet. Bang. J. Anim.

Poultry farming using modern technologies requires the employment of veterinary preparation for the prevention of infectious diseases and also feed additives for the improvement of metabolic functions and correction of body resistance. The article presents the results of clinical trials of feed additives in the form of an ionic solution concentrate of the biologically active nanosilicon "Arsil". The clinical study was performed on healthy ten-day-old broiler chicken, cross "Cobb-500", organized into three groups of 20 heads each: Group I received a feed additive at a dose of 0.5 ml per 1 liter of water, group II – at a dose of 1.0 ml per 1 liter of water and group III was the control group (on a regular diet, without feed additives). The use of the studied feed additive was carried out by watering with water for 30 days. Poultry of all groups were fed with identical feeds in accordance with regulatory requirements taking into account the age of the bird. The clinical condition of the bird was monitored daily, control weightings were performed once a week and blood samples were taken for laboratory tests on days 15 and 35 of the experiment. At the end of the experiment, a diagnostic slaughter of birds of all groups and a complete pathological autopsy with selection of material for histological examination were performed. Studies have shown that the use of the feed additive "Arsil" contributed to weight gain and average daily gain, improved the feed conversion and the tendency for the growth of the concentration of hemoglobin, hematocrit and erythrocytes in broiler chicken from the experimental groups compared with the control group at the end of fattening. The structure of the internal organs of birds of all studied groups is preserved, macroscopic changes in organs and tissues are not detected. An increase in the coefficients of mass of immune-competent organs in broiler chicken fed the feed additive "Arsil" compared with the control group was found.

This study aims to evaluate the effect of giving Garlic and Allium sativum (TUKBP) Flour as feed additives on various levels of feeding in feed consumption, Hen Day Production (HDP), egg mass, feed conversion and Income Over Feed Cost (IOFC) in laying hens. A total of 320 laying hens strain Isa Brown produced by PT. Charoen Pokphand aged 30 weeks, divided into 8 treatments and 4 replications each replication using 10 chickens. The experimental design used was a Completely Randomized Design (CRD). Eight treatment groups were as follows: basal feed + 0% TUKBP as negative control feed (P0), basal feed + virginiamycin antibiotic 0.015% as positive control (P1), and basal feed + TUKBP 0.25% (P2), 0, 50% (P3), 0.75% (P4), 1.00% (P5), 1.25% (P6) and 1.50% (P7). Data were analyzed using ANOVA test, if there were significant differences between treatments continued with Duncan's Multiple Range test. The results showed that feed with the addition of TUKBP can improve the appearance of laying hens, although it has not matched the feed with the addition of antibiotics. The use of TUKBP to the level of 1.50% in feed does not cause negative effects for laying hens. Administration of TUKBP at 1.00% level (P5) is able to replace synthetic antibiotics or as organic additive feeds in laying chicken feed.

A study of the effectiveness of the use of feed additive Liaform in relation to its effect on the growth and development of broiler chickens. For research, 2 groups of broiler chickens of 55 heads (control and experimental) from 8 days of age were formed on the principle of analogues. Feeding of the control group was carried out with standard complete feed. Feeding of the experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It is established that the studied feed additive has a positive effect on the productivity of broiler chickens, improves feed absorption. As a result of the use of feed additive Liaform live weight of broiler chickens in the experimental group was 4.3 % higher compared to the control. The average daily gain of chickens in the experimental group exceeded this figure of chickens in the control group by 4,1 %. The use of feed additives helped to increase feed conversion. The use of Liaform feed increased the protein level in poultry meat

The study included 300 unsexed broiler chicks (Hubbard) were used to evaluate (Roselle Flower) as a feed additives on the productive performance of broiler. The chicks were divided into five groups with three replicates (20 birds in each) and fed on five diets. Diet 1 (control group) dried Roselle flower powder were supplemented to the diet 2, 3, 4 and 5 as 0.25, 0.5, 0.75 and 1% respectively. The result revealed that a significant (P<0.05) increase in body weight, body weight gain, feed consumption and improvement in feed conversion ratio. Although the differences between groups for edible parts percent were not significant (Heart, Liver and Gizzard). The hematological values PCV%, RBC, WBC and H/L ratio were increased significantly (P<0.05) and cholesterol values decreased significantly as compared with control group. It can conclude that Roselle as other herbal plants may be considered as a feed additive in broiler diet would improve the productive performance, hematological and biochemical values of broiler. Diet Roselle flower supplementation of (1g/kg) might be acceptable for achieving optimum broilers performance.
