Garlic Powder

An experiment was conducted to evaluate the effects of probiotic and garlic powder instead of antibiotic on performance, carcass characteristics, oxidative enzymes and intestinal morphology of broiler chickens. A total of 200 one-day-old male broiler chicks were used in a completely randomized design. The experimental groups were including control group (without any additives) or CG, antibiotic group or AG, garlic powder group or GG, probiotic group or PG and garlic powder plus probiotic group or GPG. The broilers were weighted at the end of days 10, 24 and 42 to evaluate the body performance. At the end of experiment, four broilers randomly selected from each replicate to blood sampling and carcass traits measurement (2 chickens for each one). The use of GG significantly decreased feed intake than AG (p < 0.05) which approved in GPG when probiotic added to GG (p < 0.05). All groups, exception GG showed less feed intake than CG between days 0 to 42 of experiment (p < 0.05). GPG shows significant differences than CG between days 21 to 42 and 0 to 42 and also than GG between days 0 to 42. The use of GG and GPG significantly increased liver enzyme activities (p < 0.05). AG, PG and GPG showed a higher height and width villi than CG. So simultaneous use of probiotic and garlic powder can be a suitable alternative to antibiotics to normal performance and liver function

Abstract We studied the dietary effects of probiotic and fisetin supplementation on performance parameters, carcass characteristics and small intestinal morphology in broiler chickens. Sixty (one-day-old) Arbo Acre breed of broiler chickens were allotted into 4 groups of 15 each randomly: Group I, Control was administered only distilled water; Group II, fisetin (5 mg/kg); Group III, probiotic (4.125×106 cfu/100 mL); and Group IV, probiotic and fisetin (4.125×106 cfu/100 mL and 5 mg/kg, respectively) for the first one week of life. All administrations were performed orally through gavage. Broiler chickens supplemented with probiotic and probiotic+fisetin had greater feed intake significantly (P<0.05) at weeks 5 and 6, when compared respectively with those of the control and fisetin groups which had lesser feed intake values. Body weight gain was of great significance (P<0.05) in the probiotic-supplemented broiler chickens, while that of the control was less. Carcass quality of the probiotic-supplemented group was higher in significance (P<0.05) than any other treatment group which had lower qualities. The pH changes in the breast muscle was lesser significantly (P<0.05) in the probiotic+fisetin group, when compared with those of the control group which had greater changes. The villus height/crypt height ratio was higher in significance (P<0.05) in the treatment groups, while that of the control group was lower. In conclusion, dietary supplementation of probiotic may enhance broiler chickens’ productivity, by improving performance, carcass weight, pH, and small intestinal morphology as compared to fisetin supplementation.

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

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.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

The body of  broiler chickens is characterized by a high metabolism, which promotes rapid growth and development, but their performance indicators are largely related to housing conditions, which are known to include a number of technological stressors. With the development of stress in the body of poultry changes the course of metabolic processes, which causes changes in all types of metabolism, including protein. The aim of the study was to determine the changes in individual indicators of protein metabolism in the body of broiler chickens against the background of combined stress when included in the diet “Reasil Humic Vet” + “Laktin” and “Reasil Humic Health”. At 13th day of life, all clinically healthy poultry were exposed to combined stress – revaccination (intranasal Newcastle disease) plus cold stress (for 60 minutes by air conditioning and 5 °C in the vivarium). Material for research was selected for 3 days after the action of the stress factor (stage of anxiety), 13, 20 and 26 days after the action of the stress factor (the resistance stage). The material for the study was blood plasma, which determined the concentration of total protein, as well as the content of albumin, globulin fraction (α1, α2, β, γ). It was found that 3 days after the action of stress in chickens of Control group the development of adaptive reactions is manifested by the stability of the total protein content and redistribution of the fractional composition of plasma globulins in the form of increased albumin and α2-globulins. At different stages of development of the stage of resistance in birds of Control group, the content of total protein decreases by an average of 14.6 % due to the content of albumin by 6.9 % and α2-globulins – by 15.9 %, against the background of increasing α1- and γ-globulins by 23.1 and 33.5 % with the stabilization of individual studied indicators at the final stages of development of the resistance stage. The use in the diet of broilers feed “Reasil Humic Vet”, probiotic feed supplement “Laktin”, feed “Reasil Humic Health” under the influence of complex stress helps to increase the intensity of protein metabolism in poultry with the development of adaptation syndrome, as evidenced by the growth of total protein on average by 37.8 % (P < 0.05) and albumin – by 17.0 % (P < 0.05), which indicates an increase in the intensity of protein-synthesizing properties of the organism. In different periods of stress in the blood of broiler chickens Research groups there is an increase in the ratio of individual protein fractions, especially the content of γ-globulins - an average of 21.3 % (P < 0.05), which indicates an increase in the immune status of their body with a predominance of numerical values in the Research 1 group of poultry.

Salmonella infections remain one of the major health problems in both poultry farming and human medicine. In addition, resistance to Salmonella has emerged as a global health problem in both sectors. The present study aimed at evaluating the in vivo antisalmonellal and antioxidant activities of 95° ethanol extract of Khaya grandifoliola using broiler chickens as animal model. Animals were divided into the normal control group, negative control group, positive control group and three test groups treated with the extract at 10, 20 and 40 mg/kg respectively. The antioxidant status of broiler chickens was also evaluated by measuring the concentration of enzymatic antioxidants (catalase, glutathione peroxidase) and biochemical markers (malondialdehyde and nitric oxide). The results showed that infected animals treated with the Khaya grandifoliola extract at 40 mg/kg recovered on day 11 after the beginning of the treatment and on day 13 for those treated at the 10 and 20 mg/kg. The antioxidant assay showed that the infection led to the reduction of enzymatic markers in the body of infected animals, while the treatment increases such makers. The infection resulted in a significant increase in serum and pulmonary malondialdehyde. It also caused a significant decrease in cardiac and pulmonary nitric oxide whereas the treatment depending on the doses of the extract tends to normalize these biochemical markers. The overall results showed that Khaya grandifoliola extract can be successfully used in the treatment of avian salmonellosis as well as the management of the oxidative stress caused by the infection.

n eight week study was conducted to assess the performance, carcass characteristics and haematological indices of broiler chickens provided water from different sources. One hundred and fifty day - old broiler chicks (Arbor acre) were randomly allocated to five treatment groups (rain, stream, pipe borne water, well and borehole water respectively) in a completely randomized experimental design. The borehole water was obtained from a residential building, about 500 m to the experimental site (Federal College of Agriculture (FECA), Akure, Nigeria). Rainwater was harvested when it rained and was stored in plastic containers before it was used. It was not stored for more than three days before use. Stream water was obtained from a stream that flowed close to the students' residential area of FECA. It is sometimes drunk and is typical of streams that flow in a typical village community. Well water was obtained from a well sunk within the premises of the FECA. It was a well from where people fetched water for domestic use and was provided to the birds without prior treatment. Pipe borne water was obtained from the Water Corporation Mains that supplies FECA and Ijapo Estate, Akure. Results from the experiment revealed that there were no significant (P>0.05) differences among the treatments in terms of water intake, feed intake, weight gain, feed conversion ratio, carcass characteristics, relative weight of some organs, muscle dimensions and haematological parameters. Pipe borne water had the highest numerical values (P>0.05) for most of the performance and carcass characteristic indices measured, such as daily water intake (181.53±14.6), cumulative water intake (8.90±.71), daily feed intake (106.27±4.15), cumulative feed intake (5.21±0.20), daily weight gain (38.53±2.38), total weight gain (1.89±0.12), final weight gain (1.98±0.12), percent dressed weight (97.11±0.16%), percent eviscerated weight (81.86±3.26%), relative weights of drumstick (99.37±5.43g/kg), wings (89.10±9.69g/kg), chest (170.08±6.59g/kg) and back (159.40±18.90g/kg live weight) respectively. Water from different sources (rain, well, pipe borne water, borehole and stream) had no significant (P>0.05) effect on the performance indices, considered in the study for broiler chickens. This implies that the aforementioned water sources can be used to raise broiler chickens provided such water is free from any contaminants that could impair the health of the birds.

Dietary Treatments

The progressive increase in the cost and scarcity of conventional feedstuffs, especially energy and protein sources has resulted into a continuous effort in researching into the possible utilization of the under - exploited wild legumes in poultry feed formulation. Several Researchers had reported on the utilization of Moringa oleifera leaf meal in poultry diets whereas; few reports exist on the utilization of Moringa seed. Therefore, this study wasconducted to evaluate the effect of graded dietary levels of moringa seed cake (MSC) on the performance of broiler chickens. A total of 195, one day old Arbor Acre broiler chicks were randomly assigned into five dietary treatments of moringa seed cake, each treatment having three replicates in a completely randomized design. MSC was included at levels of 0, 5,10, 15 and 20% respectively. Feed and water were given ad- libitum. Proximate composition ofMSC showed that it is high in energy, crude protein and ether extract with3304. 39 ME kcals/ kg, 32.49 % and 17.70%, respectively. Birds fed 5% MSC diet were better than the birds on the other levels of MSC diets in terms of growth and carcass characteristics. The results obtained from growth study revealed a significant declined in, final weight, weight gain, feed intake, and feed conversion ratio as the inclusion levels of MSC increased beyond 5% in thediets. The birds on control diet had the best result in terms of final weight , daily weight gain and daily feed intake of 2974g/bird, 52.4g/bird / day and 107.51g/bird/ day respectively followed by those fed diet containing 5% MSC with 2183.4g/bird, 38.24/bird /day and 95.66g/bird /day respectively. whereas, the birds fed 20% MSC had the least (P>0.05) final weight, daily weight gain and daily feed intake of 560 g/bird, 9.26g/bird /day and 33.51g/bird/day respectively. Carcass characteristics followed similar trend as the growth parameters. Hematological indices showed significant differences across the dietary treatments, however, the results were within the normal range except for the white blood cell. It can therefore be, concluded that the inclusion of MSC in broiler chicken diet should not exceed 5% for optimum growth and general performance.

The purpose of this study was to examine the effects of daily exercise of varying duration on the body composition, weight, and feed intake of mature Swiss albino mice. Fifty-four male mice were equally divided into a control group and five exercise groups (n = 9) performing 20, 40, 60, 120, and 240 min of daily exercise on a treadmill (7.2 m/min). Feed intake and body weight were measured weekly for 10 wk. At the completion of the study the mice were killed and the animal carcasses were chemically analyzed for fat, dry matter, and protein content. The results of this study demonstrate no differences in the body weight among groups (P less than 0.97) with all groups gaining 4.5–5.8 g during the 10-wk period. However, fat content decreased significantly from 15.7% in the control to 12.0% in the 120- and 240-min exercise groups (P less than 0.05). In contrast, protein content showed an insignificant rising trend from 13.0 to 14.6% with increasing duration of exercise. Feed intake showed a nonsignificant drop during the 20-min exercise treatment and remained unchanged among groups. These data show a slight but variable appetite-suppressing effect of light exercise in mice accompanied by favorable body composition changes even in the absence of differences in body weight. These findings suggest the mouse to be an acceptable experimental model for body composition and exercise studies.
