Selection Of

Two trials were conducted with Nicholas strain turkeys. In trial 1, 300 male poults were reared to 49 days using either initial stages of 'large-turkey' feeding regime, or a situation allowing for diet self-selection of protein and energy. Within these programs, diets were supplemented with 10 ppm avoparcin, while a comparable number of controls received no growth promoter. Avoparcin improved growth rate (P < 0.01) irrespective of age, and improved feed utilization to 35 days of age. This effect was not confounded with the form in which diets were offered. In a second trial a 'broiler-turkey' feeding schedule was used, with birds slaughtered at 88 days. Diet treatments consisted of a control diet containing 33 ppm robenz and test diets containing either 33 ppm robenz + 10 ppm avoparcin or 10 ppm avoparcin alone. Avoparcin improved weight gain (P < 0.05) irrespective of coccidiostat inclusion. Feed utilization and carcass grades were not influenced by diet. The 7% improvement in body weight noted here with avoparcin was substantially greater than that previously observed with broiler chickens.

Growth Promoter

Two trials were conducted to test the effectiveness of a new antibiotic growth promoter, avoparcin, on growth and feed utilization of floor reared, mixed-sex, broiler chickens. Avoparcin 10 ppm, avoparcin 10 ppm + 3-nitro 50 ppm and lincomycin 2.2 ppm were tested in combination with various coccidiostats. To 28d (28 days), birds fed avoparcin were significantly (P < 0.05) heavier than those fed lincomycin, although neither group was heavier than control birds receiving no growth promoter. Growth promoter had no significant effect on body weight at 49d, although the coccidiostat, coban, resulted in a significant (P < 0.05) depression in growth rate. From 0 to 49d, birds fed avoparcin alone showed a significantly (P < 0.05) improved feed intake:body weight gain. In a second trial 10 and 20 ppm avoparcin were tested. Avoparcin 10 ppm resulted in a significant (P < 0.05) 3.7% increase in body weight and 4.1% improvement in feed efficiency at 49d of age relative to control birds. Increasing the level of 20 ppm resulted in no further improvement in these parameters. The effect of avoparcin was independent of the coccidiostats used in this experiment.

Three commercial premix types were fed in and duplicated to six groups of 45 broilers each at the starter pbase (0-5 weeks). At the finisher phase (5-9 weeks) each treatment group of the vital roles in starter was further divided into three groups. Nine premix combinations were used at the finisher pbase. Performance of the birds was monitored. At the starter phase, birds fed premix Z diet had a mean body weight blood (629.90gm) that was higher (P<0.05) than fed premix A diet (518.87 gm) which was also the maintenance of osmotic relations and acid higher than those fed premix U diet (414.59gm). The mean daily weight gain followed the same  trend with 16.81gm, 14.04gm, or 10.58 gm for birds fed diets that contained premixes Z A or U respectively. Birds fed a diet that contained premix Z consumed 48.80 gm daily which was  more than those for birds fed premix U in their diet (37.85gm). The feed to gain ratio was not significantly affected (P>0.05) by the premix  type fed at this phase. Poor growth rate caused by premixes with marked differences in their by premix fed at the starter phase was not completely overcome due to the premix type fed at the finisher phase varied (P<0.05) with the type of premix fed. No difference (P>0.05) was observed among the  premix types for the metabolic trials at the starter phase.

Feeding Trial

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

An experiment was conducted at the Khanpura Poultry Farm, near to the Babugonj campus of Patuakhali Science and Technology University, Patuakhali during the period from August to September, 2011 to evaluate the effect of growth promoter and multivitamin-mineral premix on the body weight gain in broiler chickens. A total of 90 ‘Cobb 500’ day-old broiler chickens were randomly divided into three equal groups (n = 30), namely Groups A, B and C. Broiler birds in groups A and B were supplemented with growth promoter and multivitamin-mineral premix, respectively in addition to commercial feed from day 4 till day 25. The dose of both the growth promoter and multivitamin-mineral premix was 2.5 g/kg of feed. Chickens of group C served as control and supplemented with commercial feed only. Body weight was recorded at three times as on day 11, 18 and 25, respectively. The mean body weight was insignificantly (p > 0.05) higher in birds of groups A (992.5±139.6g) and B (978.3±147.0g) than those of group C (926.7±133.2g). The percent increase in body weight gain compare to control was increased in both the supplemented groups (5.8% in group A and 8.8% in group B) though there was no significant difference. Based on the results, it is suggested that supplementation of growth promoter and multivitamin-mineral premix in broilers even after feeding of commercial feed has positive effect on the growth of broilers.DOI: http://dx.doi.org/10.3329/jbau.v10i2.14914 J.

The effects of feeding probiotic (PB) with or without Lincomycin 2.2% (AGP) were investigated in broiler chickens during summer. Seven hundred Cobb-500 one day old straight run broiler chicks were randomly distributed into four dietary treatments each of five replications. Four diets were compared: control; control diet plus PB (Bacillus subtilis DSM17299) at a level of 50g/100kg; control plus (AGP) at a level of 15g/100kg and control plus a combination of PB and AGP (50gm/100kg and 15g/100kg respectively). Control birds were fed on a corn-soybean based starter mash that contained ME 3000 kcal/kg and CP 24.39% from 0-21 days of age and a corn-soybean based grower mash of ME 3100 kcal/kg and CP 20.43% during 22-35 days of age. The records were kept of feed intake (FI), body weight and mortality while weight gain, feed conversion ratio (FCR) and survivability were calculated. Temperature and humidity were recorded four times daily except during extreme heat stress when measurements were made more frequently. One bird that was close to average of pen weight was taken from each replication at the end of the trial and the birds were sacrificed to determine carcass characteristics. Both performance and carcass yield data were statistically analyzed. Birds that received PB and a combination of PB +AGP treatments showed significant differences (P<0.01) from control with respect to body weight gain and FCR while feeding AGP alone although showed a decrease in feed intake. Abdominal fat was significantly (P<0.01) reduced in PB treated birds. Higher mortality was encountered in control group. Both PB alone and a combination of AGP treatments were able to show improved performance and reduced mortality, feeding PB alone may be practiced on the combined grounds of improved performance, efficiency in combating heat stress and to discourage the use of AGP in broiler diet.Asian J.

Three experiments were conducted to test the effects of Lipo-adrenal cortex (LAC), cortisone acetate (CA), hydrocortisone acetate (HCA) and glucagon (G) in broiler chickens. Oral administration of 38.7, 69.6 or 96.8 mg CA per bird significantly retarded body weight gain between days 14 and 21. HCA administered intramuscularly in doses varying from 2 to 24 mg/100 g of body weight significantly decreased body weight gain between days 14 and 28. Shank growth was similarly affected by doses over 4 mg HCA. The same doses significantly increased liver weight. At 3 months of age, birds recovered from growth retardation caused by the injection of 4 mg HCA/100 g of body weight at 14 days of age. Experimental results indicate that 2 or 4 mg HCA/100 g of body weight, administered by one injection at 14 days of age, may be used to increase growth rate variance by retarding growth.

The present study was conducted to evaluate encapsulated essential oils as an alternative anticoccidial in coccidiosis vaccine challenged broiler chickens. A total of 600 day-old male broiler chicks were provided with no-added corn-soybean meal-based control diet or diets that contained either salinomycin or EO at 60 and 120 mg per kg of diet. On day 21, half of the control groups were orally challenged with a coccidiosis vaccine at 25 times higher than the recommended vaccine dose. During 22 to 28 days (i.e., one-week post coccidiosis vaccine challenge), the challenged chickens had decrease (P &lt; 0.05) in body weight gain and feed intake but increase in feed conversion ratio compared with the non-challenged, na&iuml;ve control chickens. However, dietary EO significantly counteracted (P &lt; 0.05) coccidiosis vaccine-induced depression in body weight gain and feed intake. Increasing dietary EO linearly decreased (P &lt; 0.05) the concentrations of the volatile fatty acids. Dietary SAL and EO affected gut morphology in chickens at 20 days posthatch. Increasing dietary EO linearly (P = 0.073) increased serum catalase activity. Collectively, our study shows that dietary EO increased coccidiosis vaccine-induced growth depression and altered gut physiology in broiler chickens.

Cyproheptadine hydrochloride is a very high potent histamine and serotonine antagonist. This study was conducted to investigate the role of cyproheptadine on feed intake, body weight gain, feed conversion ratio, serum total protein, cholesterol and glucose. Red blood cells (RBC), Hemoglobin (Hb), Packed Cell Volume (PCV) and differential leukocytic count in blood of chickens were also estimated. A total of 60 one-day-old Fabro chicks were randomly divided into 2 groups. One group was received cyproheptadine at a rate of 10 ug / 100g body weight daily for eight weeks and the second group was used as a control.  The results revealed that cyproheptadine could stimulate feed intake and improve body weight gain in chickens. Erythrocyte count, hemoglobin content and PCV where increased significantly in these chickens accompanied by an increase in percentage of lymphocytes with a significant decrease in percentage of heterophiles and H / L ratio. This drug also reduces the total protein, cholesterol and glucose in serum.

Three different brands of commercial premixes were fed to a total of 270 Brown Hypeco breeds of broilers at starter and finisher stages of development. At the starter phase the broiler chickens were divided into three experimental groups. Each group was fed one type of premix in duplicates and designated A, B and C. At the finisher phase, each of the 3 groups was divided into 3 experimental group to obtain a total of mine premix combinations. Data on growth rate, feed and energy intake were recorded from which weight gain and energy efficiency were calculated. The results showed that broilers fed premix B at both development stages had better body weight and gain (20.59g/day), comsumed more DM (56g/day), energy (168 kcal / day) with better energy efficiency than broilers in other groups. Energy efficiency of broilers fed premix A was better than that of C – fed broilers at finisher phase. Energy efficiency was improved when broilers were finished with premix B irrespective of the starter premix. The poor energy efficiency of broilers fed premix A or C was attributed to deficiency of thiamine and marginal deficiency of other energy related micro-nutrients leading to nutrients imbalance.
