Abstract The effect of the dietary supplements; sugarcane molasses (prebiotic), Antox® (probiotic) and Enflorax® (synbiotic) on gut health, performance and severity of infection with Eimeria tenella in broiler chickens were evaluated in this study. Ninety (90) day-old broiler chicks were divided into six groups (A, B, C, D, E and F). Groups B to F were challenged with Eimeria tenella (2.0 × 104 oocysts/chick). Groups C, D and E were supplemented from day old with prebiotic, probiotic and synbiotic respectively, while F was administered amprolium. Groups A and B served as negative and positive controls respectively. Feed intake and performance parameters were assessed weekly for each group. After infection clinical signs, morbidity and mortality rates were monitored alongside oocysts output, gross and microscopic caecal lesions. Infected chickens exhibited clinical signs 4 days post infection (dpi) with 100% morbidity in all infected groups. Infected groups showed significant (P<0.05) drop in feed intake and weight gain from 3 - 5 weeks of age. Feed conversion ratio was highest in B but lower in the supplemented groups. Oocysts output in faeces were significantly lower (P<0.05) in the supplemented groups compared with B. Macroscopic lesion scores 7 dpi were significantly lower in the supplemented groups compared with B, though Group F had the lowest mean score. Histopathological examination of caeca tissues showed milder lesions in the supplemented groups. In conclusion, the supplements prebiotic, probiotic and synbiotic ameliorated the consequences of caecal coccidiosis in broiler chickens and therefore recommended for use in broiler production.

This experiment was conducted to investigate the effect of rosemary powder in diet on blood metabolite and performance of broiler chickens. 180 one day broiler chicks were distributed in a completely randomize design with 4 treatments and 3 replicates and 15 bird in each. Experimental treatments were included: Control (without additive), 0.05, 0.1 and 0.2 percent of rosemary in diet. In 42 day of age one bird from each replicate was selected and slaughtering for carcass traits. The results were sowed use of 0.05 percent of rosemary could be significantly increased feed intake of broiler in starter period (p<0.05). Also use of 0.1 percent of rosemary caused to significantly increase broiler body weight gain in overall of rearing period than 0.2 percent group (p<0.05). Use of 0.1 percent rosemary in diet had a significantly  feed conversion ratio (FCR) than T4 (0.2% rosemary). Experimental treatments had no significant effect on carcass traits, except in liver percent weight, which had significantly higher in T2 group (p<0.05). Also experimental treatments had no significant effect on glucose, cholesterol, triglyceride level of broiler chickens in 42 day of age. The results of this experiment showed use of rosemary powder could be improved broiler feed intake in starter period.

The effects of wet feeding and a multi-enzyme preparation on the nutritional value of wheat screenings (WS) for broiler chicks were investigated. In total, 540 1-day-old Ross-308 broiler chicks were fed a corn–soybean meal-based diet up to 29 days of age. At that time, the birds were randomly assigned to nine diets in a completely randomised design with a 3 × 3 factorial arrangement, including three levels of WS (0%, 25% and 50%, WS0, WS25 and WS50 respectively) and three processing methods (no processing, enzyme supplementation and wet feeding). The enzyme mixture contained endo-1, 4-β-xylanase (200 FXU/g), endo-1, 4-β-glucanase (50 FBG/g), endo-1, 8-β-glucanase (21 FBG/g), hemicellulase (3000 VHCU/g), α-galactosidase (3 GALU/g) and protease (260 U/g) and was supplemented at a level of 6 g/kg of diet. The inclusion of water in wet diets was in the extent of 1.2 kg/kg of diet. During the period from 29 to 49 days of age, feed intake was not affected (P > 0.05) by the inclusion of WS in the diet, whereas chicks fed the WS25 diet had a higher (P < 0.05) bodyweight gain than did those on WS0 diet. The feed conversion ratio (FCR) was improved (P < 0.05) by the inclusion of WS in the diet throughout the study. The feed intake was increased (P < 0.05) by enzyme supplementation to WS50 diet, while bodyweight gain was increased (P < 0.05) by wet feeding. Enzyme supplementation did not affect (P > 0.05) FCR, whereas wet feeding resulted in lower (P < 0.05) FCR over the entire study. The plasma concentration of glucose was increased (P < 0.05) by the inclusion of WS in the diet. The viscosity of the ileal digesta was higher (P < 0.05) in chicks receiving the WS50 diet than that in chicks receiving the other diets. The jejunal villus height was increased (P < 0.05) and the jejunal crypt depth was decreased (P < 0.05) by the inclusion of WS in diet. The jejunal crypt depth was greater (P < 0.05) in chicks receiving the wet diets than in chicks receiving the enzyme-supplemented diets (P > 0.05). In conclusion, the results from the present study indicated that broiler growth performance was improved by the inclusion of WS in the diet and also by wet feeding. These effects were largely compatible with the changes that occurred in the small intestine morphology, but not with those observed for ileal digesta viscosity.

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.

Abstract Background Heat stress is a significant problem in the poultry industry, causing a severe economic loss due to its detrimental effects on chickens’ health and performance. Dried plum (DP) is a good source of minerals, vitamins, antioxidants, and phenolic compounds. Studies have suggested that DP has several health benefits, such as maintaining the body’s redox system, immune status, and calcium hemostasis. Based on the health benefits of DP, we hypothesized that the dietary supplementation of DP would alleviate the detrimental effects of heat stress on broiler chickens. Results To test the hypothesis, day-old broiler chicks (n = 72) were randomly allocated to three treatment groups (n = 24/group): no heat stress (NHS), heat stress (HS), and heat stress with dried plum (HS + DP), and reared under standard conditions. The inclusion of 2.5% DP in the feed of the HS + DP group was made during the treatment period, while birds in other groups were provided with a standard finisher diet. After 21 days, birds in the HS and HS + DP groups were exposed to cyclic heat stress conditions (33 °C for 8 h during daytime) for 3 weeks, while those in the NHS group were reared under normal conditions (22–24 °C). Weekly body weight and feed intake were recorded to calculate the average daily gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR). Heat stress significantly decreased the final body weight, ADG, ADFI, and increased FCR compared to the NHS group, whereas dietary supplementation of DP significantly improved these growth performance parameters compared to the HS group. Furthermore, supplementation of DP significantly increased the expression of heat shock protein-related genes (HSF1, HSF3, HSP70, and HSP90), antioxidant-related genes (SOD1, SOD2, GPX1, GPX3, PRDX1, and TXN), tight junction-related genes (CLDN1, and OCLN), and immune-related genes (IL4, MUC2) in the ileum as compared to the HS group. The microbiota analysis showed significant enrichment of Bacillales, Christensenellaceae, Bacillaceae, Peptostreptococcaceae, and Anaerotruncus in heat-stressed birds supplemented with DP as compared to the HS group. Further, DP supplementation also significantly increased the concentration of acetate, propionate, and total VFA in the cecal digesta of the HS + DP group as compared to the HS group. Conclusion These findings suggest that DP supplementation effectively improved the growth performances and gut health parameters in the heat-stressed birds. Thus, dried plum can be a potential feed supplement to mitigate heat stress in broiler chickens.

The study investigated the effects of kaempferol on growth performance in two weeks old broilers challenged with Eimeria tenella. Sixty, one-day old broiler chicks were randomly allotted into six groups (I-VI) of ten broiler chicks each and brooded for two weeks with commercial broiler feed (vital feed®) and provided water ad libitum. At two weeks of age, broilers in group 1 were neither infected nor treated. Broilers in groups II- VI were infected 4 with Eimeria tenella sporulated oocyst (10 /mL) via oral inoculation. After infection was established, broilers in groups II-IVwere treated Per os with 1 mg/kg, 1.5 mg/kg and 2 mg/kg of kaempferol respectively. Broilers in group V were treated for five days with amprolium, 1.25 g/L in drinking water and those in group VI were administered normal saline, 5 mL/kg per os for five days. The experimental birds were examined daily for feed intake (FI), weight gain (WG) and feed conversion ratio (FCR). Data obtained were analyzed using pad prism version 5.0. There was a statistically significant (p<00.5) increase in the mean values of WG, FI and FCR in groups II, III and IV in a dose dependent fashion when compared to VI. There was also statistically significant (p<00.5) reduction in the mean values of WG in Group II and III than in Groups IV and V. Mean WG of Groups IV and V did not differ statistically, but there were statistically higher WG in Group V than in group IV. There were consequent high FCR values of 7.3, 5.71, 5.67, 6.19 and 7.08 for groups I, II, III, IV and V respectively compared to 4.9 for Group VI. Thus, the treatment with kaempferol in two weeks old broilers had ameliorated the effects of Eimeria tenella on WG, FI and FCR in this study.

The objective of this study was to evaluate the effects of feed supplementation with two prebiotic herbs—Origanum vulgare and Zingiber officinale—on growth performance of broiler chickens. The feed conversion ratio was determined weekly by dividing feed intake by body weight gain. A total of 400 one-day-old broiler chicks were divided into four treatment groups of four replicates of 25 chickens each using a complete design random. The four treatment groups were T0 (control), T1 (0.5% oregano), T2 (0.5% ginger), T3 (0.25% oregano + 0.25% ginger). The chicks were grown to 42 days of age. Weight gain, feed intake, conversion, carcass quality and mortality were determined weekly. Data analysis revealed that during the first 35 days of broiler chicken’s life, none of the dietary interventions had any effect on productive parameters (P > 0.05). However, during the last week of treatment, the oregano and ginger supplementation had a positive effect on weight gain and feed conversion (P < 0.05) than in the control group. In conclusion, the addition of oregano and ginger in the daily food ratio for broiler chickens during the last stage of the productive cycle improved the productive parameters, and carcass characteristics.

This study was conducted to investigate antimicrobial potentials of honey at controlling proliferation of Clostridium perfringens (Cp) and promoting growth in broiler chickens. Graded concentrations of honey solution (HS) were compared to 5.0% oxytetracycline (OTC). A total of 96 day-old White Hubbard strain broiler chicks were randomly distributed into four treatment groups of 24 chicks each in three replicates. The groups were designated as T1 for control (water only), T2 (1.5% HS), T3 (3.0% HS) and T4 (5.0 % OTC solution at 1.25g/liter). Data were collected weekly on feed intake, weight gain and efficiency of feed utilization (EFU) for six weeks. At 7th week, six birds per treatment were randomly selected, slaughtered and dissected, and 1g of caecal contents per bird was sampled into labeled sterile bottles. The samples were subjected to bacterial culturing, identification and colony counting. Results showed that feed intake was significantly (p<0.05) depressed by 3.0% HS, but EFU improved at 1.5% HS. Although the additive had no significant effect on weight, highest weight gain (1.69 kg/b) was noticed at 1.5% HS. Colonies of Cp were reduced in honey and OTC-treated groups (T2=5.2x105 ; T3= 5.0x105 and T4= 4.6×105 cfu g-1 ) compared to the control (T1; 8.7x105 cfu g-1). At 1.5% concentration, HS compared well with OTC as it reduced gut load of Cp and promoted growth in the broilers. In conclusion, addition of HS at 1.5% concentration in drinking water could therefore serve as an alternative to OTC to improve performance and reduce gut load of Cp in broilers

Abstract. In the present study, possible effects of peripheral administration of ghrelin antagonist [D-Lys3]-GHRP-6 on chicken performance, thyroid hormones level and serum biochemical parameters were investigated. Broiler chicks divided into five experimental groups were reared up to day 42. On day 21, a treatment was assigned to the five groups: group 1 (control), chickens without any administration of peptide or solution; group 2 (G50), chickens with intraperitoneal (IP) injection of 50 ng per 100 g body weight (BW) of D-Lys3 peptide on day 21; group 3 (G100), chickens with IP injection of 100 ng per 100 g BW of D-Lys3 peptide on day 21; group 4 (G150), chickens with IP injection of 150 ng per 100 g BW of D-Lys3 peptide on day 21; and group 5 (G200), chickens with IP injection of 200 ng per 100 g BW of D-Lys3 peptide on day 21. On days 21 (post-injection) and 42 (post-rearing), blood samples were obtained from the animals for laboratory analyses. Experimental groups administered the GHS-R antagonist showed less feed intake – i.e., administration of greater doses led to less feed intake (P < 0.01). Daily weight gains within groups G150 and G200 decreased (P < 0.01) in comparison with the control. The feed conversion ratio (FCR) did not differ among the groups. There was a significant difference between control and experimental groups for glucose, total cholesterol and phosphorus levels (P < 0.01) in post-injection samples. In post-injection and post-rearing blood samples, the thyroid hormone (T3 and T4) in 6 h increased in treated groups in comparison with the control (P < 0.01). The infusion of ghrelin antagonist [D-Lys3]-GHRP-6 reduces feed intake and body weight. With regard to increase in T4 level, it can be inferred that [D-Lys3]-GHRP-6 may increase metabolic rate, lipolysis and weight loss, which is similar to results obtained in mammalian species.

A study was conducted to investigate the bio-economics of feeding broiler chickens graded levels of cassava root meal based diets, as replacement for maize at 0, 25, 50, 75 and 100% to form treatment diets T1 , T2 , T3 , T4 and T5 respectively, with adjustment in soybean levels across the treatment diets to have iso-nitrogenous diets. Two hundred and forty- 4 weeks old 'Amos' strain broiler chicks were in a completely randomized design allotted randomly to five treatment groups of 48 birds each and of three replicates with each replicate having 16 birds. Parameters measured included weight gain, feed intake, feed gain ratio, price per kg of feed, price per kg of broiler and weight of carcass cuts. Data were analyzed using analysis of variances. Daily weight gain for T1 , T2 , T3 , T4 and T5 were 41.16g/b/d, 39.43, 33.47, 25.25 and 16.91 g/b/d, respectively while, daily feed intake for T1 , T2 , T3 , T4 and T5 were 113.35g, 112.75, 102.31, 93.34 and 85.94g, respectively. Results showed weight gain feed intake and feed Conversion ratio values to be significantly (P<0.05) depressed as the level of replacement of maize with cassava root meal exceeded 25%. Among the carcass parameters, only the dressed carcass (%) and thigh (%) weight values showed significant (P<0.05) decrease as the level of replacement level of maize with cassava root meal exceeded 25% while, spleen (%) and liver (%) values showed progressive increase (P<0.05) in weight as the level of cassava root meal increased in the diets. Cost of feed decreased (p<0.05) significantly with the increasing level of cassava root meal. However, it did not translate to increase in price per kg of bird. It could therefore be suggested that cassava root meal should not exceed 25% as replacement for maize in broiler finisher diets, as beyond this level growth performance is adversely impaired.

Poultry diets are largely composed of plant based materials that hold non-starch polysaccharides (NSP). The inclusion of NSP rich ingredients often reduces feed cost, but hampers a proper digestion due to anti-nutritional factors (ANF). Against this background, potency of exogenous enzymes was evaluated to upgrade dietary energy and total protein. A total of 180 broiler chickens were used in 28 days feeding trial. Six experimental diets were formulated in which maize based diet served as control (T1). Maize in the control diet was replaced by sorghum at the levels of 20% (T2), 40% (T3), 60% (T4), 80% (T5), and 100% (T6), respectively. Besides the control diet every other dietary groups were supplemented with enzyme at the rate of 50g/100kg. The broiler chicks were weighed and allotted to six dietary treatments of 30 birds each. The groups were replicated three times with 10 birds per replicate. The parameters determined for growth performance include: Final weight (g), Weight gain (g/bird), Daily weight gain (g/bird), Feed intake (g/bird), Daily feed intake (g/bird) and Feed conversion ratio (FCR). The result showed significant (p<0.05) effect on total feed intake and daily feed intake. Final weight, daily weight gain and feed conversion ratio (FCR) were not significantly (p>0.05) influenced by dietary treatments. Birds fed 60% (T4), 80% (T5) and 100% sorghum (T6) with enzyme supplementation showed higher similar statistical values 1365.00g, 1373.33g and 1373.66g, respectively for total feed intake. Haematological parameters were not significantly (p>0.05) affected by dietary treatments. Maize-sorghum based diet with enzyme supplementation had significant (p<0.05) effect on total protein, albumin and uric acid. Birds fed diets with 80% (T5) and 100% T6 sorghum levels with enzyme supplementation showed higher (p<0.05) statistical values 4.10 and 3.66 g/dl for total protein. Inclusion of sorghum up to 100% replacement level for maize with enzyme supplementation could be fed to starter broiler chicks for improved growth performance without adverse effect.
