An experiment was conducted to assess the effects of thyme and peppermint essential oils (EO) as an alternative to antibiotic growth promoter (AGP) on the performance of broiler chicken. Total 256 day-old Vencobb broiler chicks were randomly distributed into eight experimental groups with four replicates of eight birds each. Experimental groups were fed with control diet without supplementation of AGP and essential oils (T1), BMD (Bacitracin Methylene Disalicylate) antibiotic @ 500 mg/kg diet (T2), thyme essential oil @ 150 mg/kg diet (T3), 200 mg/kg diet (T4), 250 mg/kg diet (T5), peppermint essential oil @ 200 mg/kg diet (T6), 250 mg/kg diet (T7) and 300 mg/kg diet (T8). The supplementation of thyme oil @ 200 mg/kg and peppermint oil @ 300 mg/kg broiler diet significantly (p less than 0.05) improved b.wt. and b.wt gain. The peppermint oil supplementation @ 300 mg/kg was found to be more beneficial when compared among different oil-supplemented groups. The feed conversion ratio was significantly (p less than 0.05) improved with peppermint oil supplementation @ 300 mg/kg diet. A significant (p less than 0.05) reduction in the mean abdominal fat was observed in diet supplemented with higher levels of thyme oil (@ 250 mg/kg diet) and peppermint oil (@ 300 mg/kg diet). Return over feed cost was the highest in broilers assigned diet with AGP; however, it was statistically similar to the basal diet. Considering the net return over fed cost of broilers, use of thyme oil was uneconomical, but supplementation of peppermint essential oil @ 200 and 300 mg/kg diet increased the net return over feed cost and were economical, however less as compared to T1 and T2.

Finisher Diets

A 4- - day feeding trial was conducted to dermine the optianal substitution level of maize/sorghum - hased dried brewers' grains (MSDBG) for maize in broiler finisher diets. Six experimental broiler finisher diets were formulated such that 25%, 50% and 75% of the maize in diet 1 (the control) were replaced with MSDBG in diets 2, 3, and 4, respectively while diets 5 and 6 were like 3 and 4, respectievly but fortified with 4% palm oil,. Each diet was fed to a group of 48 broiler chicks for 40 days (week 4 to week 10 of age). There were no significant (P > 0.05) differences among the groups in growth rate (43,95, 45,52, 45,11, 43,01, 45,80 and 43,92g/day, respectively). At replacement levels of 50% and 75% with or without palm oil, the birds consumed significantly (P < 0.05) more feed than the group on the control diet (140.0, 151.4, 177.3, 174. 6, 174.2, 167.1 g/day, respectively). feed conversion ratio of the MSDRG groups was consequently sigificantly (P < 0.05) inferior to the control. Addition of palm oil did not produce any notiocable effect on te performance of the birds. Feed cost for production of a kilogram of brioler was markedly reduced at the 75% replacement level.

Dietary Treatments

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.

A feeding trial of six weeks was conducted to determine the effect of including rice offal supplemented with natuzyme on the performance of broilers. One hundred and seventy two 2 –week old broilers of mixed sexes were randomly allocated to four diets in a completely randomized design. The broiler chicks were allocated one of four diets containing either 0 (control), 5, 10, or 15% of rice offal. The starter diets were isonitrogenous (25% CP) but decreased in energy levels from 2,779.32 (Diet A), 2,747.73 (Diet B), 2,715.54 (Diet C) to 2,683.54kcal/kg ME (Diet D). The finisher diets were also isonitrogenous at 21% CP with each diet replicated three times. The energy levels of the finisher diet decreased from 2801.67 (diet A) to 2703.22 kcal/kg ME (diet D). The energy levels on diets B (2768.72) and C (2736.18) were higher than on diet D. All diets containing rice offal were supplemented with natuzyme at 100g/100kg feed. Overall result showed that feed intake was significantly lower (p<0.05) on the control (117.38g/bird/day) than on diets B (123.57), C (125.24) and D (123.97g/bird/day). Weight gain was significantly higher (p<0.05) on diet B (57.64g/bird) than on diets C (50.77) and D (46.88g/bird) respectively. Water intake was significantly lower (p<0.05) on the control (204.60mL/bird) than on diets B (240.44), C (231.86) and D (225.73mL/bird), respectively. Feed conversion ratio was significantly better (p<0.05) on diets A (2.36), B (2.23) and C (2.68) than on diet D (3.06) only. Feed cost/kg gain was significantly (p<0.05) better on diet A (N532.65) than on diets B (N666.75) and C (N688.92) only. Initial weight did not differ significantly across the diets but final weight was better (p<0.05) on diet B (2644.40g/bird) than on the control and other rice offal diets. Even though the control diet had lower feed intake, birds on diet B had better weight gain, feed conversion ratio, feed cost/gain and final body weight than the control and other rice offal diets and is therefore, recommended. This is because rice offal based diet on diet B has a cost saving of 8.33% over the control diet.

The objectives of the study were to investigate the effects of feeding probiotics supplemented diets with or without antibiotic growth promoter on growth performance, carcass characteristics and cost-effectiveness of commercial broilers. A gable type open sided house was used for experimental purpose. Three hundred twenty Cobb-500 one- day-old straight run chicks were randomly distributed into four dietary groups having five replications. The number of birds in each replication was 16. Four diets were considered: diet 1: control; diet 2: antibiotic growth promoter (AGP) at a dose of 15g/100kg; diet 3: probiotics (PB) at a dose of 250g/100kg and diet 4: AGP plus PB (15g/100kg+250g/100kg). Birds were vaccinated against common viral diseases as a part of disease prevention program. The records were kept of body weight, feed intake and mortality while weight gain, feed conversion ratio (FCR) and survivability were calculated. Both performance and carcass yield were statistically analyzed for interpretation. Broiler chicks that received PB showed significant improvement in performance (P<0.01) over control with respect to body weight gain, FCR, carcass yield and cost-effectiveness. Feeding AGP alone had comparatively less weight gain, net profit and almost similar feed efficiency compared with PB and AGP+PB groups but its performance was much better than that of control group. The PB fed group showed better meat yield traits. The PB alone group was also more cost effective over control. Feeding PB may be practiced in broiler diet as an alternative to AGP. Asian J. Med.

The study was carried out to evaluate the growth performance and feed cost benefit of starter broiler chickens offered graded levels of earthworm meal in replacement for fishmeal. Atotal of 120, one day old Anak broiler chicks were procured from a reputable hatchery and allotted to four treatment groups of 30 birds each. Each group was further divided into three replicates of 10 birds per replicate. A total number of four diets were used in the feeding trial. Diet 1 (control) has fish meal and no earthworm meal, while in diets 2,3 and 4, the quantity of fishmeal in the control diet was replaced by 25%, 50% and 100% respectively with earthworm meal. No significant difference (P>0.05) was observed in the performance of the birds. On the average daily feed intake of birds in diets 2 and 4 had high (P>0.05) feed intake, followed by the birds in diets 3, while the birds in diet 1 had the lowest feed intake. But there was no significant difference (P>0.05) in feed conversion ratio. The feed cost benefit analysis revealed a significant difference (P<0.05) on cost of feed consumed. Feed cost per kg was reduced as the levels of earthworm meal increased. Replacement of fishmeal with earthworm meal at 25%, 50% and 100% has the potential to improve the growth performance of broiler birds. Therefore, it is recommended to commercial poultry farmers to use earthworm meals in their poultry feeding.

A completely randomized design (CRD) was used with a total of 160 day-old commercial broiler chicks which were randomly assigned to four treatment groups with five replicates into 20 pens and brooded. Feed and water were provided ad libitum. From day old chick to 21 day, the broiler chicks were fed Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (3% fish meal and 30% soybean meal, 1: 10) was served as control diet, Diet 3 (2% fish meal and 30% soybean meal, 1: 15) and Diet 4 (1.5% fish meal and 30% soybean meal, 1: 20). From day 22 onwards, the broiler chicks were fed finisher diet, Diet 1 (5% fish meal and 25% soybean meal, 1: 5), Diet 2 (2.6% fish meal and 26% soybean meal, 1: 10, serve as control diet, Diet 3 (1.8% fish meal and 27% soybean meal, 1: 15) and Diet 4 (1.3% fish meal and 26% soybean meal, 1: 20). Weekly performances and mortality are measured. By feeding FS5 diet (5% fish meal and 25% soybean meal), the heavier body weight, increased feed consumption and feed conversion ratio of broiler chicks was observed when compared to that of other treatment groups. Conclusively, it is obvious that the ratio of dietary fish meal to soybean meal 1: 5 (FS5) improved body weight but the lower feed efficiency of this diet should be considered in economical point of view.

A total of 300 day old broiler chicks (Hubbard) were assigned to 30 floor pens (10 birds per pen) under cyclic heat stress. Three diets including a control, as well as two levels of grape seed powder (GSP) and zinc (OZ) at the rates of 2.5 g/kg GSP + 50 mg/kg OZ and 5 g/kg GSP + 50 mg/kg OZ, were supplied to the broilers for 35 days. According to the results, broiler feed intake improved (p < 0.05) in GSP + OZ groups from 3–5 weeks and on an overall basis compared to the control diet. Body weight increased (p < 0.05) in GSP-5 + OZ-50 during weeks 2–5 and on an overall basis. The findings indicated that feed conversion ratio (FCR) decreased (p < 0.05) during week 5 in broilers supplemented with GSP-5 + OZ-50. The antibody titer (HI) against Newcastle disease (ND) was higher (p < 0.05) in GSP + OZ groups compared to control treatment. The value of malondialdehyde (MDA) decreased (p < 0.05) under GSP + OZ diets compared to control. Moreover, paraoxonase (PON1) was higher (p < 0.05) in GSP + OZ groups compared to untreated broilers. In conclusion, GSP + OZ positively supported growth traits, reduced MDA, and augmented PON1 and HI titer against ND in broilers exposed to heat stress.

A feeding trial using 240, day old Anak broiler chicks was conducted in which cassava meal (CM) completely replaced maize in the control diet (A) to formulate five isocaloric and isonitrogenous diets. Dried CM blended with brewers dried yeast (BDY) formed cassayeast with 2.704 parts of CM to 1 part of BDY. The (Cassayeast) CM and BDY blend in the dietary treatments, (B,C,D and E) were 30 CM + 11.1% BDY, 35 CM +12.94% BDY, 40 CM + 14.79% BDY, and 45 CM + 16.64% BDY, respectively, and these treatments had no maize. Dietary treatment A, containing maize, which served as the control had no cassayeast inclusion, thus demonstrating the total replacement of maize by cassayeast in the other dietary treatments. Results showed that significant of maize difference (P<0.5) were observed in the control and at in one cassayeast treatment in feed intake (4.43 as against 4.22kg), body weight (1.94 as against 1.65kg), efficiency of feed utilization (feed: gain ratio 2.19 as against 2.51; gain: feed ratio 0.49 as against 0.43), respectively. However, gizzard weights were not significant. Economic analysis showed that the cost of producing a bird with the maize based diet (A) was significantly (P<0.05) higher than that with the cassayeast diets but there was not difference among the cassayeast diets (B-E). The maize based diet was most expensive (₦ 29.68 per kg diet) while diet C was the cheapest (₦ 25.57 per kg). The study demonstrated that the use of cassaveast has a place in the broiler industry, thus indicating that with proper protein balancing, cassava can completely replace maize in broiler diets.

This work aimed at investigating the potential as a growth enhancer of different dietary concentrations of turmeric (Curcuma longa Linn.) as an alternative to oxytetracyline and antibiotics and as comparable to mannan oligosaccharide for broiler chicks. A total of 252 Hubbard broiler chicks at one day of age were distributed randomly in a straight run experimental design among six treatments, each replicated seven times, with six unsexed chicks per replicate. The basal diet was administered without supplements (control group) or supplemented with turmeric at 0.5, 1, and 2 g/kg diet, or with mannan oligosacride (MOS) at 1 g/kg feed or with oxytetracycline (OTC) at 50 mg/kg feed. Growth performance, carcass characteristics, meat quality traits, blood biochemical constituents, antioxidant status and red blood cell (RBCs) were investigated. Turmeric supplementation at 1 g/kg feed significantly improved feed conversion ratio (FCR) and European production index compared to the control group and MOS groups. The results indicated that turmeric can be used at 1 kg/t feed as a phytogenic feed additive as an alternative to OTC or MOS without negative effects on the productive and economic traits of broilers. There were no differences from using OTC and MOS, while there was an increase in the European production efficiency index and the broilers’ health status.

Gas chromatography/mass spectroscopy analysis was performed to identify the chemical components of three extracted essential oils including thyme, marjoram, and sage. The antibacterial activity of the extracted essential oils against Pseudomonas aeruginosa (ATCC 9027) was investigated using disc diffusion assay, either alone or in combination with standard antibiotics (piperacillin, cefepime, meropenem, gentamicin, and norfloxacin). Results showed that the studied oils exhibited a variety of activities against the tested bacterium. Thyme oil was the most active followed by marjoram oil, whereas sage displayed no activity towards the tested organism. Thyme oil enhanced the antibacterial activity of cell wall targeting antibiotics (piperacillin, cefepime, and meropenem) by more than twofold. Marjoram oil potentiated the activity of all the tested antibiotics except norfloxacin. Sage, despite its inactivity against pseudomonas, synergistically enhanced the activity of piperacillin, meropenem, and gentamicin. Thyme essential oil, containing thymol as a major component (33.6%), exhibited higher activity alone or in combination with antibiotics than marjoram which contained alcoholic terpenes or sage essential oil that contained 1,8-cineole as its major component (29%). The investigated oils, as natural bioactive agents, may be used to enhance the activity of antibiotics towards pseudomonas.
