Heat stress is highly detrimental to the wellbeing of broiler chickens especially at the finisher stage (4-8 weeks) of production. Ameliorative effects of watermelon juice (WJ) supplement were investigated over three weeks period to monitor survival, performance and lipid peroxidation of finisher broiler chickens raised during hot season. Proximate and phytochemical analyses of the WJ were conducted. Then, one hundred five-week-old broiler chickens of 0.9kg average body weight were allotted into 4 groups- (Control, Test 1, Test 2 and Reference) each in 3 replicates in a completely randomised design. The control group received non-supplemented water, the test groups (T1 and T2) received 20% and 40% WJ respectively, and the reference group (RG) received 200mg of ascorbic acid (AA) /litre of water. Data were analysed using one way ANOVA. The results showed that relatively high survival rates were recorded in the test (T1: 84.0%, T2:100.0%) and reference (RG: 80.0%) groups compared to the control group (CG: 36.0%). Feed intake and weight gain improved significantly (p<0.05) in all the supplemented groups. The best ameliorative effects of the WJ on weight gain (1.60kg/b), Feed Conversion Ratio (0.90), survival rate (100%) and malodialdehyde (MDA) concentration (3.25) were obtained at 40% supplementation level (T2) compared to other treatments. In conclusion, WJ effectively alleviated negative impacts of heat stress in the finisher broilers at 40% supplementation level. Its supplementation is therefore recommended for broiler chickens to minimise economic loss commonly encountered in the tropical regions where extreme ambient temperature is a major constraint to poultry production.

The effects of feeding probiotic (PB) with or without Lincomycin 2.2% (AGP) were investigated in broiler chickens during summer. Seven hundred Cobb-500 one day old straight run broiler chicks were randomly distributed into four dietary treatments each of five replications. Four diets were compared: control; control diet plus PB (Bacillus subtilis DSM17299) at a level of 50g/100kg; control plus (AGP) at a level of 15g/100kg and control plus a combination of PB and AGP (50gm/100kg and 15g/100kg respectively). Control birds were fed on a corn-soybean based starter mash that contained ME 3000 kcal/kg and CP 24.39% from 0-21 days of age and a corn-soybean based grower mash of ME 3100 kcal/kg and CP 20.43% during 22-35 days of age. The records were kept of feed intake (FI), body weight and mortality while weight gain, feed conversion ratio (FCR) and survivability were calculated. Temperature and humidity were recorded four times daily except during extreme heat stress when measurements were made more frequently. One bird that was close to average of pen weight was taken from each replication at the end of the trial and the birds were sacrificed to determine carcass characteristics. Both performance and carcass yield data were statistically analyzed. Birds that received PB and a combination of PB +AGP treatments showed significant differences (P<0.01) from control with respect to body weight gain and FCR while feeding AGP alone although showed a decrease in feed intake. Abdominal fat was significantly (P<0.01) reduced in PB treated birds. Higher mortality was encountered in control group. Both PB alone and a combination of AGP treatments were able to show improved performance and reduced mortality, feeding PB alone may be practiced on the combined grounds of improved performance, efficiency in combating heat stress and to discourage the use of AGP in broiler diet.Asian J.

Shock Response

Heat stress negatively affects poultry production and animal health. In response, animals invoke a heat stress response by inducing heat shock proteins (HSPs). Scientists are actively seeking natural products that can enhance the heat shock response. The present study aimed at assessing the effects of a purified rosemary extract comprising antioxidant compounds on the heat shock response and HSP expression profile in broiler chickens. The response of broilers to HS in the presence of purified rosemary extract was assessed using an in vivo myocardial cell model. Pathological lesions of heart tissue were examined microscopically. The levels and activities of enzymes associated with heart damage and oxidative damage were detected. Immunohistochemical staining was performed for HSPs in myocardial cells. The results showed that lactate dehydrogenase (LDH), creatine kinase (CK), and myocardial CK (CKMB) levels were reduced by the purified rosemary extract before and during heat stress. Heat stress alone increased CK and CKMB levels. The levels of oxidative damage-associated enzymes were compared between the rosemary + heat stress and heat stress-alone groups. The results indicated that in terms of these enzymes, the purified rosemary extract induced a more antioxidative state. Pathological examinations showed that heat stress caused myocardial fiber fracture, karyopyknosis, and degeneration. The addition of purified rosemary extract ameliorated these lesions to some degree, preserving more of the basic structure. Heat stress decreased the cellular levels of crystallin alpha B (CRYAB) and HSP70. The addition of the purified rosemary extract significantly increased the levels of CRYAB and HSP70 during heat stress (p<0.0001). Immunohistochemistry showed that after rosemary treatment, CRYAB and HSP70 showed more intense staining compared with the no heat stress control group. In the rosemary + heat group, after 10 hours of heat stress, the staining intensity of these two proteins remained higher than in the heat stress group. Thus, purified rosemary extract could induce high levels of HSP70 and CRYAB in chicken hearts before and during heat stress. Purified rosemary extract could be used to alleviate heat stress in broiler chickens.

The objective of the present research was to assess the dietary supplementation of three formulations of essential oils (EO) in chickens under heat stress (HS). Day-of-hatch Cobb 500 chicks (n = 500) were randomly distributed into four groups: 1. HS control + control diets; 2. HS + control diets supplemented with 37 ppm EO of Lippia origanoides (LO); 3. HS + control diets supplemented with 45 ppm LO + 45 ppm EO of Rosmarinus officinalis (RO) + 300 ppm red beetroot; 4. HS + 45 ppm LO + 45 ppm RO + 300 ppm natural betaine. Chickens that received the EO showed significant (p < 0.05) improvement on BW, BWG, FI, and FCR compared to control HS chickens. Average body core temperature in group 3 and group 4 was significantly (p < 0.05) reduced compared with the HS control group and group 2. Experimental groups showed a significant reduction in FITC-d at 42 days, a significant increase in SOD at both days but a significant reduction of IFN-γ and IgA compared with HS control (p < 0.05). Bone mineralization was significantly improved by EO treatments (p < 0.05). Together these data suggest that supplemental dietary EO may reduce the harmful effects of HS.

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.

 An experiment was carried out to evaluate the effect of different level of organic acids on productive traits, carcass yields and body parts (Thigh, Back, Neck, wings and Breast) of broiler chicken. This experiment was conducted at Regional Agricultural Research Station, Parwanipur, Bara for 41 days to test the effect of organic acids inclusion in broiler feed and its effect on growth performance and carcass study. Altogether 225 day old Cobb-500 broiler birds were procured from Shivam Hatchery, Birgung and divided into 5 treatments with 3 replications (15 birds in each replication) by using completely randomized design. Concentrate feed was purchased from Posak Feed industry, Birgung. Control group (T1) was feed without organic acid inclusion and whereas T2, T3, T4 and T5 groups were fed concentrate mixture mixed with different combination of organic acids @ 400ml/ per 100 kg feed, respectively. Experimental birds were provided adlib amount of grower feed (B1) for 21 days and that after finisher feed (B3) for 20 days and had easily access to drinking water. Feed intake was recorded daily and body weight gain was measured in 7 days interval. Experiment revealed that highest weight gain was observed in T2 (2.6 kg) followed by T3 (2.5) where combination of organic acids were formic acid 65% + propionic acid 35% and formic acid 65% and citric acid 35%, respectively, however, it was not significant among diet groups. From every treatment group each birds were selected for carcass and body parts study. The study showed significant difference (P<0.5) in carcass quantity and body parts of the birds between the treatment groups. The dressing percentage of T1, T2, T3, T4 and T5 were 68.96%, 67.87%, 70.38%, 69.88% and 69.67% respectively. Experiment suggested that further study should be carried out to precise the appropriate level of organic acids inclusion and higher cost benefit ratio.

The article presents research data on indices of lipid peroxidation (TBA–active products and hydroperoxides lipids) in the blood of broiler chickens on the background of vaccination and disease Nyukasla for the actions of vitamins E and C.The study was conducted on three groups of 100 broiler birds each. Control group fed normal chicken feed. The first research group in addition to poultry feed said received – tocopherol acetate in an amount of 0.1 g/kg feed, the second – ascorbic acid 0.25 g/kg feed. The third research group chickens – tocopherol acetate and ascorbic acid at these doses. For research use blood that was in the chicken after decapitation at different ages: 11–, 27–, 34– and 41–day age. The results of performance of different age groups broiler chickens compared with the value of the index poultry 11–day age for vaccination, and a control group of birds.Studies have shown that the content of intermediate and final products of lipid peroxidation in the blood plasma of broilers depends on the age and period of immunization. Feeding high amounts of vitamin E and C in the composition of feed for broiler chickens caused a reduction (p < 0.05 – 0.001) content in plasma lipid hydroperoxides and TBA–active products. PAUL likely lower rates of broiler chickens research groups suggest reducing the negative impact of stress factors on their bodies on the background of vaccination against the disease Nyukasla. These changes were more pronounced in the blood of chickens, which in addition to the basic diet receiving tocopherol acetate and ascorbic acid.

The aim of the present study is to evaluate the effect of aqueous extract of Thonningia sanguinea on blood electrolytes of broiler chickens. To do this, two hundred (200) 15-day-old Hubbard broiler chickens were divided into 2 batches of 100 chickens each. The chickens in the control group (Batch C) received unsupplemented water while those in the test group (Batch E) received water supplemented with 10 g / L of aqueous extract of T. sanguinea for one week. Then, the zootechnical parameters such as weight growth, weight gain, consumption index and the level of serum electrolytes were determined. The results of the study showed that the aqueous extract of Thonningia sanguinea improved weight growth, weight gain and consumption index. At the same time, the results also showed that T. sanguinea did not significantly (p <0.05) affect the level of blood electrolytes of broilers chickens. From the results obtained in the present study, the aqueous extract of Thonningia sanguinea could be used to improve poultry productivity without damage on blood electrolytes.

Two hundred and twenty five day old straight run broiler chicks were utilized in completely randomized design to test the effect of restricting feed intake of four groups of chicks to 92.5% 85.0%, 77.5% and 70.0% of the unrestricted (control) group in the starter phase and following adlibitum feeding for all groups in the finisher phase. The treatments were simply designated as A, B, C, D and E. The starter phase in which the restriction was carried out lasted 28 days and the finisher phase 42 days. Parameters evaluated during the starter and finisher phases included; growth rate, feed conversion ration and mortality rate. Results show gain in weight among all groups while the group fed diet B and the control had comparable weight gain at the starter phase. The percentage weight difference between the control and each of the other dietary groups was: 4.4%, 8.4%, 8.6% and 10.4% for the treatments B, C, D and E respectively. Feed gain ration improved as the level of restriction became stricter. Following ad-libitum feeding of all grops at the finisher phase, the feed restricted groups at the starter phase voraciously increased their feed intake, thus, producing comparable performance values with the unrestricted (control) group in weight gain in the 8th week of the study. Although birds in all groups averaged more than 2000g final live weight in 10weeks, significant differences exist between groups that were fed diets C, D, and E that were restricted at the starter phase, an indication that complete compensatory growth was not obtainable. Feed gain ration improved for restricted groups. Mortality rate did not show any trend attributable to levels of feed restriction. This study shows that broiler chicks fed restricted levels of balanced diet at the starter phase but later fed ad-libitum at the finisher phase could attain a finished weight of about 2000g or more at a market age of 10 weeks (70 days) with an improvement in feed gain ration.

The present study was conducted to determine the adverse effects of high incubation temperature on growth, development and genome stability of broiler chick embryo in ovo). One hundred twenty broiler eggs from Cobb Company, USA were weighted and divided into two groups. The first group was incubated at 37oC ± 0.5oC, and the second group was incubated at 41oC ± 0.5oC from 0 to 18th day. Starting on day 4th and every other day; three eggs from each group were examined following performed measurements as weight of eggs post incubation, embryo, yolk, and egg shell for measuring growth index. Blood smear was also prepared for counting heterophiles, and lymphocytes to determine H/L ratio. Micronucleus formation and presence of binucleated red blood cells were investigated as genome stability parameters, in 2000 cells. Significant reduction (P<0.01) in growth indices was observed in embryos grown at 41oC compared to those grown at 37oC ± 0.5oC. Reduction in H/L ratio was statistically significant (p≤0.01) in embryos of 2nd group comparing to 1st group embryos. Blood of embryo from heat stress group group (2) showed Red blood cells with micronuclei and binucleated cells while no such phenomenon could be seen in embryos from control group group (1). These results suggested that heat stress is influencing cell division at telophase and induces chromosomal damage. 88% of chicks from group (1) were hatched on day 21st; only 18% of chicks from group (2) were hatched lately on day 23rd, while the others were found dead. These results indicate that heat stress not only adversely affects growth and development of embryo stem cells but also induces genome instability which intern resulted in poultry production losses.
