The present study was carried out for six weeks to investigate the effects of adding graded levels (0, 0.1 and 0.5%) of garlic (Allium sativum) powder to the basal experimental diet on the growth performance and carcass characteristics of broiler chicks. One hundred and eighty (n = 180) day old unsexed white commercial broiler chicks (Cobb-400) were randomly distributed into three dietary treatments of 60 birds/treatment and each treatment contained 4 replicates (15 birds/replicate). The dietary treatments were controlled basal diet (T1), and a diet supplemented with garlic powder at 0.1% (T2) and 0.5% (T3). Daily feed intake, weekly body weight, and residue leftover were recorded to calculate the feed conversion ratio (FCR). At the end of the experiment, six birds from each group were sacrificed to determine the carcass characteristics. Results revealed that dietary supplementation of 0.1% garlic powder (T2) significantly (p less than 0.01) improved body weight, body weight gain, feed intake and FCR as compared to birds supplemented with 0.5% garlic powder (T3) and control diet (T1). Dietary supplementation of 0.1% garlic (T2) resulted in significant (p less than 0.05) improvement in dressed yield as comparedto T3 and T1. On the other hand, comparable (p greator than 0.05) effect was observed on shrinkage loss, blood loss, feather loss, eviscerated yieldand relative weight of giblet. Thus, dietary supplementation of 0.1% garlic powder had beneficial effects on growth performance and dressed yield of broiler chicks.

The present study was conducted to evaluate the dietary effects of a marine red seaweed, Palmaria palmata, on the growth performance, blood profile, nutrient digestibility, meat quality, fecal gas emission, microbial population, and intestinal morphology of broilers. A total of 720 Ross 308 broiler chicks (1 day old), with an average body weight of 45 ± 0.50 g, were assigned to one of five dietary treatments (randomized complete block design) in a 42-day feeding trial. The five dietary treatments consisted of a basal diet (0% supplementation; control), and diets supplemented with 0.05%, 0.01%, 0.15%, or 0.25% red seaweed. Eight replicates were prepared per treatment, with each replicate consisting of 18 chicks in a cage. The results showed that there tended to be a greater increase in body weight in the seaweed-supplemented groups from day (d) 14 to 28 (p = 0.087) and d 28 to 42 (p = 0.082) compared to the control group, regardless of feed intake. Feed intake in the seaweed-supplemented groups increased linearly from d 14 to 28. A linear relationship between seaweed supplementation and the feed conversion ratio was observed from d 14 to 28 and throughout the whole experiment. The dietary inclusion of seaweed was linearly related to levels of albumin, creatinine, uric acid, and white blood cells in the broilers. Additionally, the total tract digestibility of dry matter increased linearly with an increase in seaweed supplementation. The dietary inclusion of seaweed had a beneficial effect on fecal microbes as Lactobacillus sp. counts increased and Escherichia coli and Salmonella sp. counts decreased on day 42. Histopathological examination of the intestine confirmed that seaweed dietary supplementation enhanced the heights and widths of the villi. Furthermore, the emission of fecal gases (NH3 and H2S) decreased linearly in broilers fed seaweed-supplemented diets. Dietary supplementation with seaweed led to improvements in meat quality traits, such as reductions in drip loss, water holding capacity, and cooking loss, as well as increases in relative organ weights. Based on these positive effects, dietary supplementation with seaweed in broilers can be considered a dietary option in poultry production.

This study was conducted to evaluate the growth performance and haematological profiles of broiler chickens served dietary inclusion of probiotics (Saccharomyces cereviasae) and enzyme (Bio-enzyme). One hundred and twenty, one day-old broiler chicks of Agrited strain were used for the study. The birds were randomly allotted to four dietary treatments. Each treatment contained 30 birds replicated three times to contain 10 birds per replicate in a completely randomized design experiment. The four dietary treatments were T1 Control (no probiotics and enzyme), T2 (had both probiotics and enzyme), T3 (probiotics only) and T4 (Enzyme only). The birds were given feed and water ad-libitum and the quantity of feed consumed each day was determined through weigh back techniques while the birds were weighed weekly throughout the experimental period. The experiment lasted eight weeks. The results showed significant (p<0.05) differences in the final body weight, total weight gain, average daily weight gain, total feed intake, average daily feed intake and feed conversion ratio. Chickens on treatment 2 had the highest final body weight of 3011.57g and performed better than chickens in other dietary treatments. Similar trend was observed in the haematological profile as treatment two were highest in value across the treatments and parameters measured except in packed cell volume where the highest value (36.33 %) was recorded in treatment 4. It was concluded from the study that treatment two which contained both probiotics and enzyme performed better and thus, recommended to farmers for broiler production.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

This experiment studied the effect of grind mill type [hammer (HM) or attrition (AM)], grind size (5.6 mm 4.8 mm, and 2.4 mm) and wheat type [Durum or Hard Red Spring (HRS)] on the performance, energy retention (AME), and the gut development of broilers fed these diets with or without 1.2 g water-1 g dry feed added. Twenty-four dietary treatments (2 grind types × 3 grind sizes × 2 wheat types × wet or dry feeding) were each fed to four cages of six male broilers from 1 to 17 d of age. Wet diets were prepared daily. Feeding diets with water increased 17 d body weight and feed intake of broilers compared with feeding the diets dry. Body weight and feed intake of broilers fed the HM diets were greater than those of broilers fed diets containing wheat processed by AM. Feed intake and FCR with HRS-based diets were higher than those for Durum-based diets. The AME for Durum was higher than for HRS and the ME efficiency (kcal g-1 BW) was greater, indicating a lower efficiency. The AME intake of HM ground wheat was higher than for that for wheat ground with the AM. The type of grinding, the wheat type, and the addition of water all affected the length and weight of the digestive system, likely through their effects on the rate of water absorption and passage through the gut. Particle size did not affect any measurement. Hammer milling produced a uniform particle size and less fines and may be better suited for processing wheat in broiler diets.

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.

This study was conducted to investigate the effects of dietary supplementation of Endoglucanase producing Bacillus subtilis sp. fermented product (EBFP) on growth performance and meat characteristics in broilers. A total of 480, 1 day old ROSS male broiler chicks were obtained from a local hatchery and randomly allotted to 1 of 4 dietary treatments with 6 replicate pens consisting of 20 chicks. Three additional diets were prepared by mixing 0.1% of commercial cellulase, 0.1%, and 0.2% of EBFP with the control diet and all chicks were fed experimental diets and water ad libitum. Feed intake and body weight (BW) were recorded at 0, 3, and 5 week of the experiment. At the end of the experiment, birds fed a diet containing 0.1% of EBFP had the highest BW compared to birds in other groups (P > 0.01). During 0 to 5 week the experimental period, the dietary addition of 0.1% EBFP significantly increased (P > 0.01) BW gain that was higher than that of birds fed the diet in which only a commercial cellulase was added. No significant difference among treatments was observed in carcass weight, carcass yield, left breast, and thigh meat. These results suggest that dietary addition of cellulolytic probiotics may enhance growth performance compared with the single use of probiotics or enzymes.

L-carnitine as well as lysine and methionine are amino acids of important nutritional and nutraceutical interest and are used in nutritional strategies as dietary supplements to improve feed quality characteristics in animals and broiler chicken in particular. This study investigated the effect of different levels of L-carnitine and extra levels of lysine-methionine on growth performance, carcass characteristics, and some immune system markers. Two hundred seventy male Ross 308 broilers were a fed control diet (C) and eight different diets supplemented with an excess of amino acids. In the experimental diets, identified as D1, D2, D3, D4, D5, D6, D7, and D8, extra L-carnitine, lysine, and methionine were added in excess with respect to the American National Research Council (NRC) recommendations: L-carnitine equal to NRC (D1), control diet supplemented with lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine equal to NRC (D2), control diet supplemented with lysine equal to NRC, methionine equal to NRC, and L-carnitine at 15% in excess of NRC (D3), control diet supplemented control diet supplemented with lysine at 15% in excess of NRC, methionine at 15% in excess of NRC, and L-carnitine at 15% in excess of NRC (D4), control diet supplemented lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine at 15% in excess of NRC (D5), control diet supplemented with lysine equal to NRC recommendations, methionine equal to NRC recommendations, and L-carnitine at 75% in excess of NRC (D6), control diet supplemented with lysine at 15% in excess of NRC, methionine at 15% in excess of NRC, and L-carnitine at 75% in excess of NRC (D7), and control diet supplemented with lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine at 75% in excess of NRC (D8). During the starter and growth phases, feed intake was not affected by dietary treatment (p > 0.05). By contrast, body weight and FCR were both affected (p < 0.001) during the starter period. During the finisher phase, feed consumption was affected (p < 0.05) by dietary treatment. Feed intake of broilers fed on C, D3, D6, and D7 were statistically similar (p > 0.05) (1851.90, 1862.00, 1945.10, and 1872.80 g/pen/day, respectively) and were higher (p < 0.05) than 1564.40 g/pen/day (D5). With the exception of drumsticks, neck, back thoracic vertebrae, and proventriculus weights, the economical carcass segments were not affected (p > 0.05) by the dietary supplementation of amino acids. Duodenum and ileum weights and lengths decreased with amino acid supplementation (p < 0.05). IgT and IgG titers against Sheep Red Blood Cells (SRBC) for both primary and secondary responses were not affected by dietary treatments (p > 0.05). Dietary amino acids supplementation did not affect IgM titer after the secondary challenge (p > 0.05) and had a significant effect (p < 0.05) on serum antibody titers in broilers vaccinated against Newcastle disease (NCD) and Gumboro ‘s disease at the 27th and 30th days, respectively.
