The Cost

This study evaluated a phytogenic feed additive for broiler chickens. A total of 1,632 broiler chicks were distributed into four treatments: negative control (without growth promoter); positive control (avilamycine, 10ppm + colistin, 15ppm); and two alternative treatments with 150ppm of phytogenic additive, one with a reduced Ca and P levels diet (PA-R1) and the other with lower energy, and amino acids, besides Ca and P (PA-R2). The trial was conducted with 12 replicates, each consisted of a pen with 34 birds. The alternative diets showed body weight intermediate to the two controls at 42 days, with no significant (P>0.05) treatment effect on feed conversion ratio. No treatment differences (P>0.05) on carcass yield and composition was observed. There was a tendency of abdominal fat lipids saturation, when the phytogenic additive was used, as possible consequence of a decreased level of soybean oil in the diets. A difference (P<0.001) on ingredient consumption profile was observed between the treatments. All together, this study showed a possibility to reduce the cost of total feed used to produce a broilers or a ton of body weight by the utilization of the tested phytogenic additive.

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.

The objective of this study was to evaluate the production performance of broilers with the addition of ginger (Zingiber officinale) in broiler diets in starter phases. Were used 630 broiler chicks in a completely randomized design with five treatments and seven repetitions with eighteen birds each. The treatments consist of a reference diet with corn and soybean meal and adding different levels of powdered ginger, five treatments, consisting of positive control, negative control and three levels of ginger (0.50%, 0.75%; 1.0%). Were evaluated at the end of each phase, feed intake, weight gain, feed conversion, body weight, pancreatic weight and length and weight of the intestine. The data will be submitted to analysis of variance and means to regression analysis with 5% significance. No effects of the treatments on the performance variables were observed in the initial stage of creation. With this result, at twenty-one days old, we observed the potential for substitution of growth promoters for powdered ginger. The inclusion of up to 1% of powdered ginger did not affect bird performance providing results similar to positive control treatments with growth promoter.

This study evaluated the effect of ginger on the growth performance, carcass quality of broiler chickens. 20 broiler chickens were randomly selected into two treatment groups identified as T1 and T2 with a positive control and a negative control group. Each treatment contained with five birds. Birds on T1 were treated with 1% ginger extract and T2 was treated with 2% ginger extract via drinking water. Significant variations (p<0.05) existed between the control and other treatments in mean final body weight, dressed weight, daily feed intake and feed conversion ratio. At the end of experiment (35th day) for 1% ginger extraction treatment the live body weight is 1746gm (p<0.05), dressing weight 1106.4 (p<0.05) and FCR is 1.67(p<0.05). The usage of the test ingredients had a significant effect (p<0.05) on dressing percentage. Supplementation of ginger improves the performance of broilers when added at the rate of 1% of broiler ration and can be a possible alternative to antibiotic growth promoter in the feeding of broiler chicken.Asian J.

Background and Aim: Global trend to remove the antibiotic growth promoter (AGP) from animals contributes to the exploration of successful measures to sustain production and reduces the intestinal diseases in the post-AGP era. Plant extracts, therefore, have been used to improve performance and intestinal health. Here, we conducted a study to evaluate the effects of neem (Azadirachta indica) leaf extracts (NLE) as alternatives to AGPs in broiler chickens. Materials and Methods: Sixty day-old broiler chicks were assigned to 12-floor pens, each stocked with five birds and divided into three treatment groups of four pens per treatment. The groups were: Negative control, basal diet without additives; positive control, basal diet with antibiotics and vitamins; and NLE treated group, basal diet supplemented with 0.1% aqua extract of neem leaves. Results: Overall feed intake was significantly (p≤0.05) highest in the positive control. Higher body weight, higher dressing percentage, and lower feed conversion ratio were observed in birds treated with NLE compared to the negative control group (p≤0.05) but not the positive control group (p>0.05). There was no significant variation in hematology between different groups. Furthermore, the economic evaluation indicated that the NLE treatment was found cheaper than control and antibiotic treatment in cost-benefit analysis. Conclusion: We suggest NLE might be a cheaper alternative to antibiotics in broiler production as indicated by improved body weight and feed efficiency.

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

ABSTRACT An experiment was conducted to evaluate broiler chicken performance and carcass yield in response to carbohydrase supplementation (Xylanase and Betaglucanase; XB) and association of carbohydrase and phytase (PHY). A total of 1,920 day-old male broiler chicks (Cobb 500) were distributed in a completely randomized design with 8 treatments and 8 replicates each, allocated in 64 pens with 30 chicks each. The treatments were: Positive Control (PC); Negative Control (NC): reduced ME [-120kcal/kg (Starter) and -170kcal/kg (Finisher)]; NC + XB [50g/ton]; NC + XB [100g/ton]; NC + XB [150g/ton]; NC + XB [50g/ton] + PHY [100g/ton]; NC + XB [100g/ton] + PHY [100g/ton]; NC + XB [150g/ton] + PHY [100g/ton]. The inclusion of XB (150) and XB (50, 100, and 150) associated with phytase increased feed intake than positive control when considering the total rearing phase. The feed conversion ratio of all broilers fed diets with energy reduction were worse than positive control, even with the addition of enzymes, and did not differ between them. There was no significant effect of treatments on carcass parameters.

The challenge of identifying alternatives to subtherapeutic levels of antibiotic growth promoters (AGP) in animal feed has led to increased interest in feed additives such as exogenous enzymes and direct-fed microbials (DFM). Six corn soy-based dietary treatments were designed to investigate the effect of high-efficiency xylanase alone, Bacillus spp. probiotics alone, and their combination vs. a commonly used antibiotic growth promoter (bacitracin methylene disalicylate; BMD) on live performance and environmental Clostridium perfringens load of broiler chickens with eight replicate pens per treatment. Diets were as follows: standard diet (positive control; PC); 130 kcal/kg reduced-energy diet (negative control; NC); NC with xylanase (NC + Xy); NC with probiotics (NC + Pro); NC with xylanase and probiotics mix (NC + XyPro); and NC with BMD (NC + BMD). Data were analyzed as one-way ANOVA. At 35 and 42 days, birds fed with NC + XyPro and NC + BMD were heavier (P &lt; 0.05) than birds fed with NC. Improvement in feed conversion ratio (FCR) (P = 0.0001) was observed from 1 to 42 days by ~3 points in both NC + XyPro and NC + BMD compared to NC. The NC + XyPro reduced lesion scores by 66% compared to PC and NC. Litter C. perfringens cell count was reduced by ~16% with supplementation of XyPro or BMD. It can be concluded that a blend of xylanase (10 XU/g feed) and Bacillus spp. [1 × 105 colony forming units (CFU)/g feed] can be used as an alternative to AGP in low-energy broiler diets.

The present study was planned to evaluate the response of broiler chicks to diets containing graded levels of spearmint (Mentha spicata).  A total of 200 , five days-old, unsexes (cob) broiler chicks were used. Chicks were weighed individually and assigned randomly to five groups of 40 chicks per treatment and each treatment was subdivided to four replicates of 10 chicks each. Five experimental diets were formulated (A, B, C, D and E) to meet the nutrient requirements of broiler chicks. The experimental parameters examined were growth performance, serum metabolite, electrolyte and enzyme activities and economic appreciable. Diet (A) Negative      Control (NC), a basal diet without antibiotic or spearmint,  diet B as Positive Control (PC) basal diet supplemented with antibiotic (Neomycin 16 mg/Kg), diets C,D and E were basal diet  supplemented with spearmint at levels of 1,1.5,and 2%, respectively. Result obtained showed that addition of spearmint improved significantly (P<0.05) the performance (body weight gain and feed conversion ratio) of broiler chicks compared to group fed on NC while no significant (P<0.05) differences between chicks fed on diets supplemented with spearmint  and PC group observed, no significantly difference was found in feed consumption between all treated groups. The mortality rate did not influenced by the dietary treatments. Results revealed no significant differences (P<0.05) observed among all treatment groups in the carcass dressing percentages, Supplementation of broiler diets with spearmint at various levels was resulted in significant (p>0.05) reduction of abdominal fat, serum cholesterol, and AST enzyme activity compared to both NC and PC groups while the levels of urea, total protein, glucose and ALP and serum electrolytes levels remained unchanged. The highest profitability ratio (1.13) was obtained from the diet (E) supplemented with 2% spearmint. This study showed that spearmint when added as growth promoter in broiler diets has a similar effect on performance as that of antibiotic without any adverse effects.

Consumer concern for drug residues in meat and eggs as well as ban imposed on the use of antibiotics in animal feed as growth promoter call for alternative search. A 56days feeding trial was conducted to investigate the effect of ginger inclusion with and without yeast supplementation on performance, carcass characteristics, gut micro flora of broiler chickens. A total of One hundred and eighty day, one old Arbor acre broiler chicks wereallotted on weight equalization basis to 6 dietary treatments in a 3 × 2 factorial arrangements (3 levels of ginger (0%, 4% and 5%) with and without yeast (0%, 1% levels). The treatments were replicated thrice with ten birds per replicate. Feed and water were provided ad- libtum. Performance showed that birds on combination (5% ginger and 1% yeast) recorded highest weight (1527g) with better feed conversion while least weight (1202g) and least feed conversion were recorded with birds on ginger only. Highest eviscerated weight (1362.50g) and dressing percentage (72.79%) were recorded in broiler chicks on 1%Yeast + 5% Ginger while least values (1087.50g, 62.39%) were recorded with birds on yeast only. Total bacteria count increased from 1.20 x106cfu/ml (control) to 1.70 x106cfu/ml in diets supplemented 1% yeast and 5% ginger as well as Lactobacillus count increased with supplementation level Total anaerobic count decreased from1.10 x106cfu/ml in control diet to 0.68 x106cfu/ml in birds fed1% yeast and 5% ginger likewise coliform, clostridium and bacillus counts decreased with the additives (yeast and ginger) inclusion. It can be concluded that inclusion of ginger and yeast at 5% and 1% respectively in the diets improved performance and reduced pathogenic biota without detrimental effects in broiler chickens and might therefore serve as a natural substitute for synthetic growth promoters.
