Abstract There is dearth information on the role of fisetin as an antistress agent in ameliorating heat stress in broiler chickens. Here, we experimentally compared probiotic, an antioxidant and antistress agent, with fisetin, an antioxidant agent with little or no report on its antistress effect. Sixty-day-old broiler chickens (Arbo Acre breed) were allotted into 4 groups of 15 birds each as follows; control, fisetin, probiotic, and fisetin + probiotic groups, respectively. All administrations were performed orally through gavage for the treatment groups. The environmental and cloacal temperature (CT) parameters were measured bi-hourly at Days 21, 28, and 35 from 7:00 to 7:00 hr, during the period of study. The environmental parameters exceeded the thermoneutral zone for broiler chickens. The probiotic-supplemented group had the least overall mean CT values all through the experimental period. Based on our findings, fisetin was not a potent antistress agent in mitigating heat stress in birds.

The gain body weight and Spoilage of meat broiler which giving jaloh extract to combine with chromiumABSTRACT. A study was conducted on broiler chickens under heat stress to evaluate the effect of combined jaloh (Salix tetrasperma Roxb) extract with chromium mineral in the body weight, value of feed ratio conversion, and time to meat to become decomposed. Twenty four of 20-day old Cobb female broiler chickens were randomly assigned and divided to 4 treatment groups. Completely randomized design was used in this study. The treatments were as follows: 1) chickens given no heat stress and jaloh extract nor chromium (tCp); 2) chickens under heat stress without given jaloh extract nor chromium (Cp); 3) chickens under heat stress and given jaloh extract in 1.000 mg/lt drinking water (Cp+Ej); and 4) chickens under heat stress, given jaloh extract in 1.000 mg/lt drinking water, and chromium in 1.000 ug/lt drinking water (Cp+Ej+Cr). Heat stress given was 33 ± 1oC of cage temperature during 4 hours per day within 15 days. Jaloh extract and chromium treatments in drinking water were given at 2 hour before cage temperature reaching 33 ± 1oC and were stopped being given after 1 hour, when cage temperature back to room temperature. On the 16th day of the study chickens were measured before slaughtered. Samples obtained were chicken meat that taken from breast part (musculus pectoralis). The result suggested that either giving jaloh extract per se at the dose of 1.000 mg/lt in drinking water or combine it with chromium that given two hours before cage temperature reaching 33 ± 1oC, can prevent chickens from decreasing their body weight, decreasing value of feed ratio convertion, and extending time to meat to become decomposed.

The research was conducted to study the effect of heat stress on blood parameters in indigenous sheep. Nine sheep were divided into three groups which were almost similar in age, sex and weight. Three groups were divided as zero hour (T0), four hours (T4) and eight hours (T8) heat exposure to direct sunlight. During experimental period temperature–humidity index (THI) value was calculated as 27.09 which indicate T4 and T8 groups were subjected to heat stress condition for at least four hours and eight hours respectively every day. The amount of red blood cell (RBC), hemoglobin (Hb%) and packed cell volume (PCV%) were increased significantly (p<0.05) with the increase of heat stress but the amount of white blood cell (WBC) had no significant difference (P>0.05) among the treatment groups. It can be concluded that heat stress had significant changes on some blood parameters in indigenous sheep. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21253 J. Bangladesh Agril.

Current European animal transportation law contains only a few and vague indications concerning how to move lambs of less than 26 kg. Moreover, little information is available in the literature about factors affecting these lambs’ welfare. We investigated the effect of space allowance and ambient temperature on the welfare of unweaned Lacaune lambs during a simulation of long-distance transportation (19 h). Three groups of lambs (N = 130) were housed in equally sized pens for 19 h, Control (C; n = 39; 0.27 m2 per head), Low Space Allowance (LSA; n = 52; 0.20 m2 per head), and Heat Stress (HS; n = 39; 0.27 m2 per head) groups. LSA lambs had lower space allowance than C but were tested at the same temperature, within their Thermoneutral zone (range = 12–18 °C). The HS lambs were, instead, subjected to higher temperatures (range = 19–30 °C). Scan sampling of behavior was conducted, eye temperature and body weight were also recorded. LSA and HS lambs showed more discomfort behaviors (p < 0.05) and higher eye temperatures (p < 0.001) compared to C lambs, while HS lambs additionally showed a decrease in body weight over the experimental period (p < 0.001). This study indicates that lower space allowances and higher temperatures impact negatively the welfare of lambs transported for slaughter suggesting that the regulation should be implemented taking these factors into account.

AbstractHeat stress is one of the major challenges which the poultry industry faces during summer in tropical and subtropical regions. This study was conducted to evaluate the impact of Vitamin (Vit) E, C and/or probiotics on improving tolerance of broiler chickens to chronic heat stress (CHS). A total of 294, 1-day-old Cobb-500 broiler chicks were allocated into seven treatment groups; Thermoneutral group was raised under a thermoneutral condition during 25–42 d of age. The other six groups were raised for three successive days per week at 36±2ºC and 75–85% relative humidity for 7 h daily: heat stressed group, Vit E (100 mg/kg diet), Vit C (200 mg/kg diet), Vit C+Vit E, probiotics (Saccharomyces cerevisiae and Lactobacillus acidophilus at 2 g/kg diet) and Vit C+Vit E+probiotics. Exposure to CHS decreased body weight gain (BWG), feed intake (FI), and abdominal fat. It had adverse impact on feed conversion ratio (FCR), packed cell volume (PCV), monocyte, basophil, total protein, and phagocytic activity while increased plasma cholesterol and aspartate aminotransferase (AST) compared to the thermoneutral group. Vit E, Vit C or probiotics alone decreased the adverse effects of CHS on growth rate throughout the experimental period. Vit C and E were equally potent during the experimental period, but were less effective than the combination of both vitamins. Vit E increased the dressing percentage and abdominal fat as compared to the thermoneutral group, but decreased AST while increasing basophil, monocyte and globulin compared to the heat stressed group. In addition, serum albumin and AST of Vit E were lower compared to Vit C, but cholesterol was higher. Vit E increased red blood cells and white blood cells, but plasma cholesterol was increased compared with the heat stressed group. Vit C increased PCV, lymphocytes, monocyte, basophil and albumin and decreased neutrophil. Both vitamins without/with probiotic induced a further increase in basophil, serum total protein, and albumin. It could be concluded that supplementation of Vit E, Vit C, probiotics, and different combinations reduced some of the adverse effects of CHS, and Vit E+Vit C+probiotics was the most effective for economic traits followed by Vit E+Vit C or probiotics.

scholarly journals A total number of 192 male one-day-old broilers chickens were randomly divided into four treatment groups of 48 chickens. Chickens of group one fed a plain diet without any supplement (control), while the diets ib groups two, three, and four were supplemented with Whole Yeast (WY, Saccharomyces cerevisiae, 0.1%), Yeast Cell Wall (YCW, 0.3 %), and Yeast Extract (YE, 0.07 %), respectively. At the end of the experimental period (35 days), the bodyweight of chickens and the feed intake of each cage were measured, and then the feed conversation ratio was calculated. Blood samples were also collected to measure the serum components and relative spleen, bursa of Fabricius, and thymus gland. The results obtained indicated that all productive performance parameters improved in response to the feeding supplementation. Blood parameters indicated that the treated groups had a significantly higher level of serum total protein and albumin as well as significantly lower serum total lipids and cholesterol. The enzyme activities of ALT, AST, and ALP were significantly reduced by WY, YCW, and YE supplementation. The relative organ weights of the spleen, bursa of Fabricius, and thymus increased significantly in broilers fed with WY, YCW, and YE, and the highest values were observed in the chickens fed with WY. It can be demonstrated that the supplementation of WY or its derivatives in the diet of broiler chickens improves the production performance as well as the physiological and immunological parameters, and consequently produce a healthier chicken

A trial was carried out to investigate the possible role of Ostertagia circumcincta, coccidiosis and level of protein in the diet in the development of swelling disease in Angora goat kids. Eighty Angora goat kids were bought from 5 producers whose flocks had a history of swelling disease. These kids were kept in enclosures at Grootfontein Agricultural Development Institute near Middelburg (Eastern Cape) for the duration of the experiment. The animals received a combination of the following treatments: a) high protein vs normal protein diet; b) Ostertagia circumcincta infection or no O. circumcincta infection; c) coccidial infection or no coccidial infection. Data recorded included weekly body weight, weekly total plasma protein levels (TPP), weekly faecal egg counts, weekly coccidial oocyst counts and haematology at Weeks 1, 5, 9, 13 and 16. The goats were also monitored daily for any clinical symptoms. There was no specific trend in any of the parameters measured among the different treatment groups at any stage during the experimental period. The goats were shorn during Week 10 of the experiment. On Monday 6 September 2004 (Week 12 of the study), 19 of the goats developed some subcutaneous oedema. The Saturday (4 September 2004) was rather hot (30 oC), followed by very cold rainy conditions (11 oC) on Sunday (5 September 2004). Twelve of the goats developed what can be described as little oedema, while 7 developed moderate oedema. The number of goats that developed oedema was fairly evenly distributed among the various treatment groups. As far as the specific treatments are concerned, more goats on the normal protein diet developed moderate oedema than the goats on the high protein diet. Body weights of goats that developed moderate oedema were lower throughout the experimental period than body weights of goats that developed little or no oedema, while TPP of goats that developed moderate oedema were lower from Week 5 of the study onwards. There were also no significant differences at any stage throughout the experimental period in faecal egg counts, faecal coccidial oocyst counts or any of the blood parameters between goats that developed moderate oedema, little oedema and those that did not develop any oedema. No goats developed full-blown swelling disease during the course of the experiment. It is possible that the treatments applied in this study are not inductive of the disease, or the effects of the treatments were not severe enough to induce swelling disease.

This experiment was conducted to examine the effects of 1-α(OH)D3 alone or in combination with different levels of cholecalciferol on performance, and tibia parameters of one-d–old male broilers fed a tibial dyschondroplasia (TD)-inducing diet. A total of three hundred male broilers were randomly allocated to 5 treatment groups with 4 replicates. The dietary treatments consisted of TD inducing diet, TD inducing diet supplemented with 5 μg per kg of 1-α(OH)D3; TD inducing diet supplemented with 5 μg per kg of 1-α(OH)D3 and 1,500; 3,000 or 5,000 IU cholecalciferol kg-1 of diet. At 42 d of age, broiler chickens fed diets containing 1-α(OH)D3 and 1,500 IU cholecalciferol kg-1 of diet had higher body weight (p < 0.05). In the complete experimental period the best FCR and the highest daily weight gain were obtained in broilers supplemented with 1-α(OH)D3 and 1,500 IU cholecalciferol kg-1 of diet. Broilers supplemented with 1-α(OH)D3 and 1,500 IU cholecalciferol kg-1 of diet had significantly lower incidence and severity of TD in comparison with other groups. In conclusion, the results indicated that the supplementation of 1-α(OH)D3 in combination of 1,500 IU cholecalciferol kg-1 of diet could maximize tibia bone ash, performance and prevent TD in broilers fed TD inducing diet.

The effect of jaloh extract combined with probiotic and chromium on the haematology profiles and ND antibody vaccine of broiler given heat stressABSTRACT. 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 108 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 ± 1oC 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.
