The aim of this research was to study the biochemical properties of a new protein-rich feed additive produced by the short-term intense thermal treatment and subsequent enzymatic hydrolysis of the wastes of poultry slaughter and primary processing (feathers and fluff). It was found that this feather-based fermented feed additive contained high amounts of crude protein (86.52%); and the content of easily digestible low-molecular peptides in the additive was 9% higher compared to fishmeal. The amino acid profiles of the additive and fishmeal were compared. The effectiveness of substituting the additive for fishmeal in the diet of broiler chicks was demonstrated by the in vivoexperiments. The results showed that the digestibility of the dietary nutrients was higher in broilers that were fed the new additive compared to those fed fishmeal, which resulted in higher meat productivity: the average daily weight gains in additive-fed broilers was 3.82% higher (p <0.01) compared to fishmeal-fed control broilers, the dressing was 1.4%higher, the muscle in the carcass was 2.1% higher, and the feed conversion ratio was 3.57%lower. The sensory evaluation scores of the meat and broth were also higher in the additive-fed broilers.

An experiment was conducted to investigate the effect of supplementing of exogenous phytase enzyme on productivity of commercial broilers. Four strains of commercial broiler such as Fast feather, Arbor acres, Cobb-500 and Hubbard classic each having 78 numbers were reared for a period of 5 weeks. A total number of 312 day old broiler chicks were distributed into two dietary treatments i.e. basal diet (Control-T0) and basal diet supplemented with phytase enzyme 1g/kg feed (supplemented-T1). The results indicated that broilers fed on diets supplemented with phytase have gained more body weight when compared with control group (P<0.05). The first and second highest body weights were recorded for the strains Cobb-500 and First feather broilers, respectively, which feed on diet containing phytase.   Feed consumption varied significantly between the broilers on different dietary regimes. Significant differences (P<0.01) were found in feed conversion ratios among the birds fed on diet with phytase enzyme. The lowest feed conversion ratio was in Cobb-500 fed on phytase diet where as the highest was in Fast Feather provided with only basal diet during the 5th week of age. Average feed conversion ratios were 1.73 and 1.86 for the supplemented and control group respectively. Use of phytase as feed additive in the diet resulted in high profitability/ broiler. Net profit per live broiler was the also higher in treatment group compared with control groups of birds. The highest net profit per live broiler was observed in Arbor Across strains fed on phytase diet. The result of the present study suggests that the addition of dietary phytase enzyme in the diet of broiler may increase the production performance and reduce the cost of production.Bang. J. Anim.

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.

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.

This study investigated the effects of summer savory (Satureja hortensis L.) extract (SSE) on growth, plasma constituents, immune response, and gut microbiota of broiler chickens. A total of 300 day-old broiler chicks were randomly assigned to five dietary treatments containing five replicates of 12 birds each. The treatments consisted of a controldiet without feed additive and experimental diets supplemented with four levels of SSE (100, 200, 300, and 400 mg/kg, respectively). Results showed no significant effect of SSE supplementation on broiler body weight gain (p > 0.05), but feed conversion ratio was significantly (p < 0.05) improved when fed 400 mg/kg SSE compared to control. Most of the blood parameters and immune response criteria studied were improved (p < 0.05) by SSE supplementation. There was no dietary effect on Lactobacilli count (p > 0.05); conversely, Escherichia coli count was reduced and the Lactobacilli/E. coli ratio improved with SSE (p < 0.05). Based on our findings, it was concluded that supplementation of the diet with SSE up to 400 mg/kg sustained growth traits and improved the feed efficiency and health status of broilers. However, more research is needed on this subject in order to better understand the mode of action of the extract used.

Early Performance

Several methods have been introduced to estimate the optimum level of dietary nutrients such as metabolisable energy (ME), crude protein (CP), and lysine (Lys) in broiler chicken production. Performance optimisation is usually measured as maximising body weight gain and minimising adjusted feed conversion ratio (Adj FCR). One useful method is to model a system that requires an explicit mathematical input-output relationship. Group method of data handling-type neural network (GMDH-type NN) and genetic algorithm (GA) is used to model and optimise an output in an imprecise environment (Yao, 1999). The purpose of this study was to apply the GMDH-type NN and GA methods to provide an optimised formula for broiler chicken performance based on the dietary level of ME, CP, and Lys.

The study included 300 unsexed broiler chicks (Hubbard) were used to evaluate (Roselle Flower) as a feed additives on the productive performance of broiler. The chicks were divided into five groups with three replicates (20 birds in each) and fed on five diets. Diet 1 (control group) dried Roselle flower powder were supplemented to the diet 2, 3, 4 and 5 as 0.25, 0.5, 0.75 and 1% respectively. The result revealed that a significant (P<0.05) increase in body weight, body weight gain, feed consumption and improvement in feed conversion ratio. Although the differences between groups for edible parts percent were not significant (Heart, Liver and Gizzard). The hematological values PCV%, RBC, WBC and H/L ratio were increased significantly (P<0.05) and cholesterol values decreased significantly as compared with control group. It can conclude that Roselle as other herbal plants may be considered as a feed additive in broiler diet would improve the productive performance, hematological and biochemical values of broiler. Diet Roselle flower supplementation of (1g/kg) might be acceptable for achieving optimum broilers performance.

The experiment was conducted to compare the effects of different sources of Spirulina and vitamin mineral premix as feed additive on the growth performance of broiler. Two hundred day old broiler chicks (COBB-500) were divided into five groups such as T1-(Feed containing 0.30% Vitamin mineral premix+0.0% Spirulina), T2-(Feed containing 0.15% Vitamin mineral premix+0.15% Spirulina from China), T3-(Feed containing 0.0% Vitamin mineral premix+0.30% Spirulina from China), T4-(Feed containing 0.15% Vitamin mineral premix+0.15% Spirulina from Myanmar) and T5-(Feed containing 0.0% Vitamin mineral premix+0.30% Spirulina from Myanmar) having four replication in each group containing 10 birds/replication. The experiment was conducted for 28 days (Completely Randomized Design) with ad libitum feed and water. Live weight was numerically higher (P>0.05) in T4 in 4th weeks of age. Lower feed intake observed in T3 and T5 which was mainly 50% replacement of vitamin mineral premix by Spirulina. After end of the feeding trial feed conversion ratio (1.66) in control group was higher (P<0.05) than other groups (1.63, 1.64, 1.59 and 1.61 respectively in T2, T3, T4 and T5). Dressing percentage (63.12%), breast weight (21.22%) and thigh weight (8.54%) were higher (P<0.05) in T4 than all other groups. Concentration of total cholesterol in blood plasma (64.42mg/dl) and serum albumin (1.75g/dl) was lower (P<0.05) in T4. It could be concluded that Spirulina from Myanmar is better than China and 50% synthetic vitamin mineral premix could be replaced by using Spirulina from Myanmar for better growth of broiler. Bang.

An experiment was conducted to evaluate the effect of feed wetting and fermented feed on the performance of broiler chicks. Four experimental diets were used in the study. Diet 1, was a conventional commercial broiler starter feed. Diet 2 was a commercial broiler starter feed in a 1:1.2 dilution with water. Diet 3, was a water diluted commercial feed inoculated with Bactocell? and fermented for 24 hours at 35oC in an incubator. Diet 4 was fermented feed add with 6% copper sulphate solution at the rate of 1ml to 10g of feed, to then incubated for 24 hours. 180 day old Anak 2000 broiler chicks were randomly assigned to the four experimental diets in a completely randomized design (CRD). Each treatment group was replicated four times with 15 birds per replicate. Results showed that feed intake and weight gain were significantly higher (P<0.05) in birds fed fermented feed and non-fermented liquid diets. Birds fed dry feed consumed significantly (P<0.05) more water than those on liquid feed. Birds receiving liquid feed (fermented and non-fermented) showed significantly (P<0.05) superior feed conversion ratio over the group fed dry feed. There was no significant (P>0.05) difference between the birds fed liquid diets in all the response parameters measured. The results also indicated that the treatments had no significant effect on the carcass characteristics of the birds. The results of this experiment showed that feeding fermented and unfermented liquid diets improved the performance of the birds.

The experiment was conducted with 108 day old straight-run Hubbard Classic broiler chicks for a period of 35 days to investigate the effects of citric acid, commercial herbal additive (Keqinling) and their combination on growth and carcass traits of broiler. The dietary treatments were control (T0), 0.5% citric acid (T1), 0.2% Keqinling (T2) and combination of 0.5% citric acid +0.2% Keqinling (T3).  Final live weight was 1615, 1710, 1707 and 1795g in control, 0.5% citric acid, 0.2% Keqinling and their combination groups respectively. The highest live weight gain (1748g) was found in combination group followed by 0.5% citric acid (1664g), 0.2% Keqinling (1660g), and the lowest (1568g)in control group. The highest feed consumption and feed conversion efficiency was observed in T3 and the lowest in group T0. Significantly (p<0.05) the highest dressed yield (%) was found in 0.5% citric acid group (56.65) than combination (55.73) and Keqinling (55.18) and lowest in control group (54.59). Citric acid reduced the pH of the both feed and faces. The cost of production (Tk/kg broiler) was lowest in citric acid group (Tk. 76.22). Net profit per broiler production was found in 0.5% citric acid group (Tk. 10.03/broiler) followed by combination (Tk. 9.28), Keqinling (Tk. 7.31) and control group (Tk. 6.98) respectively. The addition of 0.5% citric acid and 0.2% Keqinling individually or their combination increase the performance of broiler but citric acid showed better response than Keqinling.Bang. J. Anim.
