Abstract The purpose of this study was to compare the effect of a standard inclusion level of inorganic zinc to organic form at lowered level on the bone development in growing male Ross 308 chickens, assessed on the basis of mechanical, geometric, and histomorphometric parameters of limb bone, and bone zinc content, as well as hormones of somatotropic axis. A total of 80 one-day-old male Ross broiler chickens were randomly allocated to 2 groups of 40 chickens each. The control group was fed with a corn-soybean meal basal diet providing the recommended zinc amount (100 mg×kg-1) from zinc oxide, and the experimental group was supplemented with glycinate chelate providing 25% of the total requirement of the microelement recommended for Ross 308 broiler chicks. The mechanical and histomorphometric parameters and geometry of tibia were determined as well as the serum concentration of growth hormone, IGF-1, osteocalcin and leptin. The serum concentration of Zn, Cu, Ca, Mg, Fe, P and zinc bone content were determined. The results showed that birds fed with the diet supplemented with organic zinc in the amount of 25% of the recommended amount did not exhibit weight and general growth disorders and had an unchanged concentration of growth hormone, leptin, and IGF-1. The serum concentration of Zn, Cu, Ca, Mg, Fe, P did not differ between groups. The contents of zinc detected in bones in the controls and the group supplemented with the organic source did not differ as well. Although tibial mechanics and geometry remained unchanged, histomorphometry revealed a disproportionately large osteoporotic bone. The changes in tibial trabecular bone as a result of the diet supplemented with glycinate chelate only in 25% of the total requirement of the microelement recommended for Ross 308 broiler chicks seems to be insufficient for tibia development.

Tonic root has been speculated to improve Libido and this could have effect on performance and carcass traits of the animal. Afifty-six days experiment was conducted to determine meat quality of Abor acre Strain of broiler chickens fed graded dietary inclusion of supplemental white ginger (Mondia whitei). One hundred and eighty, one day-old broiler chicks were assigned to five treatment groups with three replicates per group. Birds on treatment one were fed concentrate with no supplements, those on treatment two had concentrate + 0.5g Mondia whitei per kg feed, treatment three had concentrate + 1g Mondia whitei per kg feed; Treatment 4 had concentrate with 1.5g Mondia whitei per kg feed and treatment five had concentrate + 2g Mondia whitei per kg feed. At the end of the eight weeks feeding trial, three birds each from each replicate of five treatment groups were randomly selected, deprived of food for 12 hours prior to slaughtering. After the traditional slaughtering method, feather plucking and evisceration were done and breast muscles were excised from the carcasses for quality parameters evaluation. The results showed significance (P< 0.05) in some measured parameters such as colour, yellowness (b*) and Lightness (L*). Highest (P<0.05) triglyceride content of meat (145.33 mg/dL) was recorded in the meat of birds fed inclusion level at 0.5g/kg and the lowest value (91.67mg/dL) in the meat of birds fed inclusion level of 1g/kg. Breast muscles had the highest (P<0.05) pH score 6.72 at 1g/kg inclusion level and least value of 6.51 was in the control group. Dietary inclusion of Mondia whitei showed no significant (P>0.05) effect on cholesterol, high density lipoprotein (HDL) and low-density lipoprotein (LDL). Although superoxide dismutase (SOD) and water absorptive power were not significantly (P>0.05) influenced, cooking and refrigeration loss as well as thiobarbituric acid reactive substance (TBARS) in meat were significantly (P<0.05) lowest in birds fed 1g/kg dietary inclusion level of Mondia whitei. Some phytochemicals and overall sensory acceptability were statistically influenced by the dietary treatments.

Effects of supplemental dietary lysine and methionine in a Groundnut Cake (GNC) based diets on meat and bone characteristics of broiler chickens were investigated. In a completely randomized design, a total of 168 one - day – old Arbor acre broiler chicks were randomly allocated to seven dietary treatments each in triplicate of eight birds per replicate. The Seven starter and finishers’ diets were: GNC based diets without any amino acid (lysine or methionine) supplementation (T1); GNC diet + 0.2% lysine (T2); GNC diet + 0.4% lysine (T3); GNC diet + 0.2% methionine (T4); GNC diet + 0.4% methionine (T5); GNC diet + 0.2 lysine and 0.2% methionine (T6) and GNC diet + 0.4% lysine and 0.4% methionine (T7). Experimental diets and water were offered to birds ad libitum in an experiment lasting six-week. At day 42, two birds per replicate were slaughtered, meat and bone characteristics determined. There were significant variations (P<0.05) in the crude protein (%) and ether extract (%), pH1 and pH2 of meat. Thiobarbituric acid reactive substances composition of meat at days 0, 5, and 10 were similar (P<0.05) and were not affected by dietary amino acid supplementation. Tibiotarsal index (mg/mm) of bone (22.10, 27.25, 33.35, 31.40, 28.70, 31.45 and 29.75 for broilers on T1, T2, T3, T4, T5, T6 and T7, respectively) were increased significantly (P<0.05) by amino acid supplementation. Significantly differences (P<0.05) were observed in the calcium, phosphorus and potassium (%) contents of broilers’ bone across treatments. Supplemental lysine and both lysine and methionine improved meat quality and bone development of broiler chickens in this study.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Introduction Increasing the immune system's function of fighting infectious diseases is very important in the poultry industry. Ginger, scientifically known as Zingiber officinale, belongs to the Zingiberaceae family. The use of ginger in the diet of poultry increases serum levels of superoxide dismutase enzymes and glutathione peroxidase, which are considered to be important antioxidant enzymes. The main objective of the present study is to evaluate the effect of ginger on the spleen tissue of broiler chickens. Material and Methods The specimens comprised 2 groups of 20 Ross breed broiler chicks, for 42 days and were then, examined and tested. The diet was supplemented with 1 g/kg of ginger powder from the beginning of the rearing period. Blood samples of the chicks were randomly collected to measure the levels of hemagglutination (HI). The removed spleens were fixed with 10% formalin buffer. The specimens were cut in 5-micron diameters and stained with hematoxylin and eosin. Results and Conclusion There was a statistically significant difference in the mean of HI blood titers between the chicks in the growth period and final period groups (p < 0.05). The white-pulp tissue samples were more clearly seen in the treatment group than in the control group, and also, it was observed that the wall of the central artery of the white pulp was thicker in the ginger-treated group as compared with the control group. The nutritional value of ginger may vary. Thus, it is necessary to investigate the effect of this plant final on weight gain; the serum factors associated with the metabolic chart, and the response of the immune system to this plant.

Over Time

The prevalence of an antibiotic-resistant strain of Salmonella Typhimurium definitive phage type 104 (DT104) has increased dramatically in recent years resulting in increased morbidity and mortality in both animals and humans. Colonization and shedding of Salmonella Typhimurium DT104 was studied in broiler chickens in two trials. In trial 1, 180 day-of-hatch chicks (n = 60 per group, n = 30 per replicate) were challenged with 106 CFU DT104 (wild-type isolate from poultry) or were commingled with a seeder chick challenged with 106 CFU DT104. In trial 2, 360 day-of-hatch chicks (n = 120 per treatment, n = 30 per rep) were divided into three groups. Chicks in the susceptible group were commingled with two seeder chicks that were orally challenged with 107 CFU/bird of a pan-sensitive strain of Salmonella Typhimurium DT104. Chicks in the resistant group were commingled with two seeder chicks that were orally challenged with 107 CFU/bird DT104 used in trial 1. For both trials, a control group was not exposed to DT104, composite fecal samples were evaluated twice weekly for levels of Salmonella shedding and 20 chicks per group were necropsied weekly and their cecal contents were cultured. At hatch all groups were colonized with naturally occurring Salmonella Senftenberg and Salmonella Mbandaka (trial 1) or Salmonella Senftenberg and Salmonella Ohio (trial 2) prior to exposure to DT104. Throughout the study, the level of Salmonella spp. shedding in feces (trial 1 means 3.1, 2.9, and 3.0 log10 CFU per g feces for challenged, seeder, and control groups, respectively) or ceca (trial 2 means 2.9, 2.9, and 2.5 log10 CFU per g ceca for resistant, susceptible, and control groups, respectively)did not differ among groups. In trial 1, colonization of DT104 remained constant at higher levels in the challenged group (mean 87%, P &lt; 0.01), increased over time in the seeder group (10 to 50%, P &lt; 0.02) and was not recovered from the control chicks. Salmonella Mbandaka colonization remained steady within each group with challenge and seeder groups maintaining higher levels of colonization than the control group. Salmonella Senftenberg colonization levels tended to decline (P = .058) over time in the challenged group (20 to 0%) and significantly decreased (P &lt; 0.01) over time for both the seeder (80 to 0%) and control chicks (85 to 10%). In trial 2, the percentage of chicks colonized with susceptible DT104 declined (r = 0.90, P &lt; 0.05) over the course of the trial from 45 to 0%, while recovery of the resistant DT104 persisted at a mean percentage of 27%. DT104 was not recovered from the control chicks. Salmonella Ohio colonization levels tended to decline (r = 0.79, P &gt; 0.05) over time in the control group (75 to 20%) and significantly decreased (P &lt; 0.05) over time in both susceptible and resistant groups (40 to 10%, r = 0.82 and 55 to 5%, r = 0.85, respectively). Salmonella Senftenberg was recovered from the control group at low frequency throughout the trial and was not recovered from the other groups. For either trial, no apparent affect on morbidity or mortality was observed. Introduction of DT104 by commingling may induce colonization resulting in persistent high levels of shedding in flocks simultaneously with other Salmonella species.

A total of 100 one-day-old healthy broiler chicks were used to study the effects of lincomycin and bacitracin on some hematobiochemical and immunological parameters. Chicks were divided into four equal groups, 25 each. The first group was kept as control; the 2nd group was received 0.5 g of lincomycin per liter; the 3rd group was received 100 mg bacitracin per liter and the 4th group was administered both lincomycin and bacitracin, each at the above-mentioned dose. Drugs were given in drinking water for 5 successive days from 20th to 25th day of age. Bodyweight was recorded at the beginning of the experiment and at 1st-day post administration where body performance was recorded. One day post administration, blood samples were collected for estimation of hematobiochemical and immunological alterations. The obtained results revealed that broiler chicks administered lincomycin or bacitracin or both revealed a marked increase in bodyweight, weight gain, phagocytic activity, phagocytic index, erythrocytic count, hemoglobin level, packed cell volume, total leukocytic count, serum total protein, albumin, total globulin, α, β and γ globulin. Furthermore, a significant elevation in malondialdehyde associated with a marked reduction in albumin-globulin ratio, serum total lipid, cholesterol and triglyceride and a significant decrease in catalase and superoxide dismutase, were recorded, compared with the control group. In conclusion, lincomycin and bacitracin either alone or in combination have positive impacts on growth performance, immunological and hematobiochemical parameters of broiler chickens. So, it is recommended to use both drugs as growth promoters in broiler chickens.

Background and Aim: Wood vinegar is a product generated from the combustion and distillation of wood and other plant materials. It has been shown to suppress bacteria, resulting in healthier livestock and increased yields. This study aimed to determine the efficacy of drinking water supplemented with wood vinegar on growth performance, intestinal health, and gut microbial of broilers. Materials and Methods: A total of 120 Ross 308 1-day-old male broiler chicks were randomly distributed in a completely randomized experimental design. The study consisted of three treatments containing four replicates, with 10 birds in each. Treatments were given 0.5% and 1.0% (V/V) wood vinegar supplemented in drinking water, while no supplementation was given to the control group. The animals were raised in an open-house system. All groups were provided with a commercial diet and drinking water ad libitum. Analysis of variance was conducted using the general linear model procedure to compare the levels of wood vinegar supplementation in drinking water on growth performance, intestinal morphology, and gut microbial. Results: No significant differences (p>0.05) were found for body weight gain, feed intake, feed conversion ratio, and water consumption between groups during the starter (1-21 days old), grower (22-35 days old), and whole (1-35 days old) growth periods. Moreover, no significant differences in villi height and crypt depth (p>0.05) at 21 and 35 days of age were found. In addition, no significant difference in terms of lactic acid bacteria and Escherichia coli was found between the different treatments. Conclusion: Drinking water supplemented with wood vinegar was not found to have an effect on the growth performance and gut microbial of broiler chickens in the present study. However, the supplementation of wood vinegar in drinking water could improve intestinal morphology.

The results of the influence of feed additives: acidulent Versal liquid and probiotic bifidobacteria PKB on the growth dynamics and some hematological and immunological parameters of broiler chickens are presented in this article. The research was conducted on 30 broiler chicks. There were formed 3 groups. There were 10 chicks in each of them: a control group didn't get any feed additives; 1–st experimental group got feed and acidulent Versal liquid solution at the recommended dose of 1 ml /1 l of water; 2–nd experimental group got feed with probiotics bifidobacteria PKB at the recommended dose of 1g / 1kg of feed and acidulent Versal liquid solution at the recommended dose of 1 g/1 l of water. The 15th and 30th day blood were collected for hematological and immunological parameters checking.It was found, chicks that have got feed additives achieved more intensive increasing of average live weight and daily gain during this period. The live weight of broiler chicks from the second experimental group was higher at 76.5 grams, compared with the control and the 136.6 h – compared with I research group in case of using acidified and probiotics bifidobacteria. Average daily increasing were 49.93 g in the control group, 48.21 g and 52.36 g according to another experimental groups. There was a tendency of hemoglobin increasing on the 30–th day of experiment in all experimental groups. The hemoglobin concentration increased by 1.09 times in the 1–st group and in 1,20 times in the 2–nd group. The number of leukocytes was increased in the experimental group. It was also increased by 16.6% in the 1–st group and by 44.4% in the 2–nd group. Phagocytic activity of pseudo eosinophils increased in all experimental groups on the 30–th day of the feed additives using. The most important increasing by 7.2% was in the 2–nd group. There was also a tendency of the phagocytic index increasing in all experimental groups of chicks on the 30–th day of this investigation. It was established that the using of acidulent and PKB probiotic preparation of food at feeding broilers improves hemoglobin levels. It also promotes to leukocytosis, phagocytic pseudo eosinophils activity and improves the overall condition and immunological reactivity.

Ad Libitum

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.

Three hundred 21-day-old broiler chicks were reared using a 3 x 3 factorial model in a completely randomized design with 10 treatment groups having 3 replicates of 10 birds each. The birds were raised on a commercial starter diet at the starter phase before being allotted into dietary groups in a 21-d feeding trial at the finisher phase. The interaction between treatment and varying inclusion levels of processed-fermented Jatropha curcas (L) kernel meals (JKM) on the performance of broiler chicks was investigated. Jatropha curcas kernels were subjected to three different processing methods, namely: raw defatted fermented meal (RDFM), cooked defatted fermented meal (CDFM) and lye treated defatted fermented meal (LDFM). Each meal was included at varying inclusion levels of 2.5%, 5.0% and 7.5% such that diet 1 (control) contained 0% JKM while diets 2, 3, 4 contained 2.5%, 5.0% and 7.5% RDFM, diets 5, 6, and 7 contained 2.5%, 5.0% and 7.5% CDFM and diets 8, 9, 10 contained 2.5%, 5.0% and 7.5% LDFM. Feeding differently processed-fermented JKM to these broilers did not (p>0.05) compromise the feed conversion ratio. The results indicated an improvement (p<0.05) in the weight gain of broiler chicks fed CDFM and LDFM at 2.5 and 5.0% inclusion levels respectively. There were significantly (P<0.05) elevated levels of alkaline phosphatase and creatinine in their blood serum. The kidney, lungs and proventriculus of birds fed CDFM showed significant differences (p<0.05) among the treatments. Therefore, finisher broilers could tolerate up to 5.0% inclusion level of LDFM.
