“…Previous study by Putsakum et al (2007) demonstrated no difference in the intestinal microbial populations between ACTH-treated and control birds, whereas in other studies environmental factors, such as stressful conditions influenced bacterial colonization of the gastrointestinal tract (Lan et al, 2004;Selig & Patterson, 2004;Gareau et al, 2007). As mentioned earlier, type and severity of stress and host intrinsic factors might explain the controversy among these reports.…”

“…It has been reported that the GIT microflora cooperate in the development of the hypothalamus-pituitary-adrenal (HPA) axis (Sudo et al, 2004), which is necessary for the normal stress response. On the other hand, stressful experience can disturb the balance of the intestinal microbiota and lead to the excessive growth of pathogens while decreasing the proportion of beneficial bacteria such as lactobacilli and bifidobacteria (Fuller, 1999;Lan et al, 2004;Selig & Patterson, 2004;Lutgendorff et al, 2008). Thus, any changes in the GI tract microbiota due to stress may negatively influence HPA axis activities, for example, Gareau et al (2007) showed that maternal separation in mice increased blood corticosterone level as compared to the control.…”

A study was conducted to investigate the effect of two Lactobacillus strains on hypothalamus pituitary adrenal (HPA) axis activity induced by supposedly unpleasant handling (UH) of broiler chickens. The three treatments were: (1) non-handled chicks fed basal diet (control); (2) unpleasantly handled-chicks fed basal diet (UH-BD) and (3) unpleasantly handled-chicks fed basal diet supplemented with the probiotic, lactobacilli (UH-BDL). Chicks were exposed to UH from days 1 to 21. Treatment UH-BDL received probiotics in their diet for the whole experimental period. Blood corticosterone (CS) concentrations were monitored at 14, 28, 35 and 42 days of age and selected caecal bacterial groups were enumerated in 14-day old birds. Unpleasant handling significantly increased blood CS concentrations at 14 and 28 days of age. Blood CS concentration decreased with age over the course of the experimental period. Lactobacillus supplementation did not reduce blood CS concentration in broilers in the UH-BDL treatment. Moreover, the UH treatment did not alter caecal bacterial numbers in the 14-day old broilers while the probiotic numerically increased total anaerobes and lactobacilli. Overall, it seems as if the efficacy of lactobacilli to modulate stress-related high HPA-axis activity depends on gastrointestinal tract microbial alteration. However, Lactobacillus salivarius subsp. salicinius JCM 1230 and L. agilis JCM 1048 were able to reestablish a proper microbial balance in the caecum of the chickens. ________________________________________________________________________________

| Over the years, development of poultry genotypes is driven mainly aiming higher production at optimal temperatures. However, recent increase in extreme heat wave events and enhanced sensitivity of modern poultry genotypes to heat stress has become a major concern leading to significant economic losses to the poultry industry. In India, per capita consumption of poultry meat and eggs is significantly lower than the minimum recommended by Indian Council of the Medical Research and there is need for significant increase in poultry productivity to fulfil these requirements. Conversely, in sub-tropical countries like India where summer is severe, accomplishing higher production under current scenario is a challenge. Earlier intervention strategies including environmental management and nutritional supplementation have been inconsistent in poultry for managing heat stress. Therefore, there is scope for exploring innovative approaches, including genetic marker-assisted selection of poultry breeds for increased heat tolerance and application of molecular techniques in poultry breeding to improve poultry productivity in a sustainable manner. Hence, keeping in view the present situation, it is essential to understand various cellular and molecular mechanisms involved in poultry production including physiological and immunological aspects of the poultry birds under heat stress using molecular biology tools that can help in development of poultry breeds which are better adapted to changing climate.

“…Pada penelitian terdahulu menunjukkan bahwa pemberian ekstrak etanol kulit batang jaloh dapat mengurangi stres dan memperbaiki performan ayam akibat cekaman panas (Sugito et al, 2007;dan Sugito, 2008). Adanya laporan hasil penelitian yang menyatakan bahwa pemberian probiotik (Lan et al, 2004, dan Ahmad, 2006 serta pemberian mineral kromium (Cr) juga dapat mengurangi dampak cekaman panas pada ayam broiler (Ahmad et al, 2004dan Toghyani et al, 2007, maka penggunaan ekstrak jaloh dikombinasikan pemberiannya dengan probiotik dan atau mineral kromium diharapkan dapat dioptimalkan efeknya dalam mengurangi gangguan fungsi tubuh akibat stres panas pada ayam. Tujuan dilaksanakannya penelitian ini adalah melihat pengaruh pemberian ekstrak jaloh bila pemberiannya dikombinasi dengan probiotik dan mineral kromium dalam air minumnya terhadap profil hematologi dan titer antibodi vaksin ND pada ayam yang mengalami cekaman.…”

The purpose of this study is to determine the respons of chicken broiler under heat stress that given drinking water contained extract jaloh combined with probiotic and Cr mineral in the profile of haematology and antibody respons of Newcastle Disease vaccine. Twenty four of 20-day old Cobb broiler chickens were randomly assigned and devided to 6 treatment groups. Completely randomized design was used in this study. The treatments were as follows: 1) chickens under heat stress, given jaloh extract, probiotic, and chromium (P1); 2. chickens under heat stress, given jaloh extract and probiotic (P2); 3. chickens under heat stress, given jaloh extract and chromium (P3); chickens under heat stress, given jaloh extract (P4); 5. chickens under heat stress without given jaloh extract nor chromium and probiotic (P5); and 6. chickens given no heat stress and jaloh extract nor chromium and probiotic (P6). Extract jaloh dose applied is 1.000 mg/lt water, dose of probiotic is 10 8 cfu/lt drinking water, and chromium given in the form of chloride chromium with dose 1000 ug/lt water. Local heat stress is provided by increasing cage temperature to the range of 33.0 ± 1°C during 5 hours per day u within 15 days. Jaloh extract, probiotic, and chromium treatments in drinking water were given at 2 hour before cage temperature reaching 33 ± 1 o C and were stopped being given after 1 hour, when cage temperature back to room temperature. Blood was taken before chickens were ethanuatiated. The result suggested that giving jaloh extract to combine it with probiotic, and chromium has no significant effect in hematology profile. When combined extract jaloh with chromium (Cr), has potencial capability to stimulate improvement built of antibody (as immunomodulator) on broiler chicken heat stress.
