The bio-efficacy of Escherichia coli-derived phytase produced by thermo-protective coating technology (coated phytase) was evaluated in mash or pelleted broiler diets. Three hundred and twenty-four broilers were divided into 54 groups of six birds and fed nine corn-based diets (six replicates per diet) from 1 to 22 d of age. The nine diets were a positive control (PC) (calcium, 0.9% and non-phytate phosphorus, 0.45%) fed as mash plus 2 × 4 factorial of a negative control (calcium, 0.78% and non-phytate phosphorus, 0.26%) fed as mash (NC-M) or pellet (NC-P) and with coated phytase at 0, 500, 600 or 700 FTU kg-1. The diets were pelleted at 80°C, and pressure load of 40 psi. Body weight gain (BWG) for the PC diet was higher (P < 0.001) than that for the NC-M or NC-P diet. The BWG and tibia ash were linearly increased (P < 0.001) by increased level of the phytase in NC-M or NC-P diet. The BWG for NC-M or NC-P diet reached that of the PC diet when phytase was supplemented at 600 or 700 FTU kg-1. In conclusion, the coated phytase improved nutrient utilization in broilers, and its bio-efficacy was unaffected by the pelleting process.

Garlic (Allium sativum) is a popular spice in Bangladesh. Its beneficial effect as growth promoter in poultry has not been studied. Broilers were grouped into four: T1 (1% garlic), T2 (2% garlic), Pc (ciprofloxacin positive control) and Nc (negative control). Aqueous extract of garlic (1% and 2%) was administered with drinking water. T1 group (1%) showed better performance with regard to body weight gain than T2 (2%), positive and negative control. In T1 group, significant difference was observed in terms of live body weight gain and dressed weight but no significant differences in feed conversion ratio, offal’s weight and in blood parameters. It is suggested that 1% aqueous extraction of garlic improves growth and carcass qualities in Broilers.Bangl. vet. 2015. Vol. 32, No. 1, 1-6

The objective of this study was to investigate the efficacy of Artemisia splendens on performance, some serum biochemicals content, lymphoid organs and gut health of broiler chickens challenged with coccidia. This study was conducted at university of Duhok, college of agriculture. A total of 200 day-old Ross 308 chicks were assigned in to 5 treatments (4 replicates pens of 10 birds/pen): unchallenged control (negative control); challenged control (positive control); challenged supplemented with salinomycin in feed  (anticoccidial); challenged supplemented with Artemisia splendens  in drinking water (AS1) and challenged supplemented with Artemisia splendens in feed (AS2). On day 9, challenged birds were inoculated with 5000 sporulated oocysts of Eimeria. The results showed that on day 24, challenged birds in negative control, anticoccidial AS1 and AS2 had higher weight gain and feed conversion ratio compared to positive control. No significant differences were detected between Birds in AS1, AS2 Anticoccidial and negative control for body weight gain and feed conversion ratio. On day 35, birds in AS1 as negative control and anticoccidial groups had higher (P<0.01) body weight gain and feed conversion ration compared to positive control. Negative control, anticoccidial, AS1 and AS2 birds significantly increased villous height and villous height/crypt depth and decreased crept depth when compared to positive control at day 24. The serum globulin concentration of AS1 birds was significantly higher than birds in negative control, positive control and anticoccidial. In conclusion, these results demonstrated the protective effects of Artemisia splendens against performance during coccidiosis challenge.

A study evaluated the effects of limestone sources with different solubility on the efficacy of two phytases in broilers. A 2×5 factorial arrangement was employed with two commercial limestone sources and five diet treatments; a positive control (PC) diet with 7.2 g/kg P and 9.6 g/kg Ca, and a negative control diet containing reductions of 1.87 g/kg available P, 1.99 g/kg Ca and 0.4 g/kg Na, supplemented with either Buttiauxella phytase (PhyB) or Escherichia coli phytase (PhyE) at 500 or 1000 FTU/kg diet. The two limestone sources were feed-grade commercial products with different particle sizes and solubility (fast-soluble (FS) 100%; slow-soluble (SS) 26% soluble after 30 minutes at pH 3) containing similar levels of Ca. Diets were fed to one-day-old Ross 308 males (n=2,400) with 30 birds/pen and eight pens/treatment in two phases (starter 0-10 d and grower 10-21 d). On d 21, ileal digesta was collected from 12 birds/pen to determine apparent ileal digestibility (AID) of P and Ca, and myo-inositol hexakisphosphate (IP6) disappearance, and tibias from four birds/pen for ash determination. The SS limestone improved body weight gain (BWG), feed intake (FI) and FCR vs FS limestone in starter/grower phases (P<0.05), and improved AID of P (P<0.05) and IP6 disappearance (P<0.05) at d 21. There was an interaction between limestone and phytase on BWG, FI and FCR in the grower phase (P≤0.05) whereby FS (vs SS) limestone reduced BWG at either dose of PhyE, but only at 500 FTU/kg of PhyB. At an equivalent dose, PhyB had higher BWG and feed intake than PhyE (P<0.05). At 1000 FTU/kg, performance was equivalent (BWG and FI) or superior (FCR) to the PC, PhyB produced greater tibia ash, AID of P and IP6 disappearance (P<0.05). The findings showed that the effects of limestone particle size on phytase efficacy varied with phytase source and dose.

Maximum Improvement

Ross 308 broiler chicks (n = 240) aged 1 day were assigned to five groups for eight replicates (six chicks for each) (3♂ and 3♀). Basal dietary groups were supplemented by 2000, 4000, and 6000 mg/kg cinnamon (CN) for 21 days. Basal diet alone was used as a negative control, and basal antibiotic diet (Colimox) was used as a positive control. At 10, 14, and 21 days of age, chicks that received 2000 mg CN and Colimox had a higher body weight, resulting in an increase in body weight gain. CN also resulted in the maximum improvement in the feed conversion ratio and feed efficiency over 1–21 days at the level of 2000 mg/kg. At days 10, the maximum relative breast weight was 2000 mg/kg of CN. Mean serum albumin concentrations, duodenal villus height, and goblet cell density increased (p < 0.05) by 2000 mg/kg of CN, and mean serum globulin and total protein concentrations and crypt depth increased (p < 0.05) by 6000 mg/kg of CN compared with control. Increased cecal Escherichia coli number was CN dose-dependent. In conclusion, dietary inclusion of 2000 mg/kg CN can be applied as an alternative to in-feed antibiotics for broiler starter diet.

A 21-day experiment with day-old broilers was conducted in order to assess the effect of phytase supplementation to different cereals-soybean meal based diets on broiler performance and tibia ash. Diets were formulated to contain 4 different cereals (maize, wheat, triticale and barley), 2 levels of dietary calcium (0.6 and 1.0%) and 3 levels of supplemental phytase (0, 500 and 1 000 PU/kg). Supplemented phytase had beneficial effects on broiler performance. It significantly increased body weight gain (P &lt; 0.0003) and feed consumption (P &lt; 0.0361) by 6 and 7% in comparison with the control groups, respectively. No influence on feed conversion ratio and tibia ash was detected. Both body weight gain and feed intake were also significantly influenced by different cereals (P &lt; 0.0001 and 0.0348, respectively). The increasing dietary calcium level resulted in a significant increase in body weight gain (P &lt; 0.0024) and tibia ash (P &lt; 0.0016). Effects of 500 and 1 000 PU/kg were not statistically different between themselves. &nbsp;

Two trials were conducted on floor pens to evaluate the performance of broilers fed with diets contained different carbohydrases enzyme programs at different ages. Trial 1- The body weight gain (BWG) was affected by the Negative Control (NC) treatment (P<0.05). However, when the birds were fed with the NC diet + Amilase (AMY)+Xilanase (XYL), the BWG improved and reached the same level as the Positive Control (PC). Trial 2- The birds received enzymes supplementation in the total phase and others only in the grower phase.The ME reduction by 120 kcal/kg increased the feed conversion ratio (FCR) (P<0.05) when compared to PC and none of the enzyme programs was able to recover the performance. It can be concluded that it is possible to supplement with AMY during the role period of broiler chicken life or use an enzymatic program with AMY or AMY+XYL only in the grower phase.

Phytase produced by Escherichia coli was fed to broiler chicks fed graded levels of available phosphorus (0.25–45%). A positive control involved Natuphos® a fungal phytase commonly used in poultry nutrition. Feeding diets with only 0.25% available phosphorus from 1 to 13 d of age resulted in reduced feed intake and weight gain, with associated loss in tibia weight, tibia ash and tibia phosphorus content (P < 0.01). Adding 600 IU phytase kg−1 diet corrected these problems, and both sources were equally efficacious for most parameters studied. Key words: Phosphorus, phytase, chicken

The objective of this study was to determine the effect of Fusarium oxysporum degraded Brewer dried grain (BDG) on the performance and nutrient utilization ofbroiler chicken at starter and finisher phases. Undegraded and degraded (BDG) werewas used to compound rations for broiler birds for 8 weeks. The undegraded BDG was used at 7% inclusion level and the degraded BDG was used at 3, 5, and 7%. A total of 150 day old chicks were randomly selected and allocated for 5 treatments. Thirty 30 birds were allocated to each treatment with three replicates each. Fusarium oxysporum was inoculated into BDG through Solid State Fermentation for a period of 7 days. This was used as degraded sample. There was improvement in the crude protein, ash, and gross energy after biodegradation. Biodegradation led to reduction in crude fibre, cellulose, hemicellulose, and detergent fibre content. At  starter phase, there were significant (P<0.05) (P=0.05) differences in feed consumption and body weight gain and the highest feed consumption (FC) and body weight gain  (BWG) were found in treatment 5, which contained 7% degraded BDG (DBDG) and the FC and BWG they were 88.93 and 41.07g/bird/day, respectively. At the finisher phase, there were significant (P=0.05) differences in both the average feed intake and the average body weight gain by the birds. The highest feed intake was found in treatment 5 (140 g/b/d) and the highest body weight gain was also observed in treatment 5 (78.21g/b/d). Significant differences (P=0.05) were also observed for the feed conversion ratio at the finisher phase. The best value (1.64) was recorded at the control treatment and this was followed by the value recorded for treatment 5 (1.79). The relative cost benefits revealed that it is profitable to feed broilers with F. oxysporum degraded BDG. The results showed that F. oxysporum was able to enhance the feeding value of BDG and this impacted positively on the feed consumption and body weight gain by the birds.

Hypercholesterolemic Diet

The current study examined the attenuating influence of dietary carrot pomace powder (CaPP) on hypercholesterolemia and various oxidative stress-associated with biochemical parameters in hypercholesterolemic rats. Thirty two male albino rats weighing 110±10 g were divided into four groups, the first group received the basal diet only and served as (negative control), the second group received the hypercholesterolemic diet and served as positive control, the other groups received hypercholesterolemic diet supplemented with 10%, 20% CaPP for six weeks. The obtained results revealed that groups supplemented with 10% and 20% CaPP significantly decrease total lipid, total cholesterol, triglycerides, low density lipoprotein cholesterol, liver enzymes: alanine aminotransferase, aspartate aminotransferase compared to positive and negative groups. Organs weight, body weight gain significantly decreased compared with positive control. Moreover dietary carrot pomace powder can used to reduce the body weight and reducing hypercholesterolemic complications. In addition, dietary carrot pomace powder serves to improve the blood picture and to reduce the blood glucose level in hypercholesterolemic rats and could use in obese people for body loss. Data of kidney function (Urea) record an increase in CaPP 20% level (26.9±2.96) but this increase was non significant with the negative control group (26.6±3.1).
