Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Garlic Oil

This study was carried to evaluate the “Effect of Garlic (Allium sativum) oil inclusion on carcass quality, growth performance and cost implication of broiler chickens”. A total of 180 day–old-(Arboacre) broiler chicks purchased from a reputable hatchery was used in the study which lasted for eight (8) weeks. The birds were divided into four experimental groups; each group was further subdivided into three replicates of fifteen birds per each in a Complete Randomized Design (CRD). The birds were fed on two basal diets (Starter and finisher) in an experiment which lasted for eight weeks. The garlic oil (Allum sativum) was added to the basal diet at (0.00, 0.1, 0.2, 0.3%) level respectively. The treatment were T1, T2, T3, and T4 with T1 serving as control. Growth performance, carcass characteristics, and cost implication were recorded. At the end of the experiment, the birds were slaughtered, dressed to estimate the different parameters. The result showed that the diet with 0.3% garlic oil inclusion had significantly (P<0.5) highest body weight and highest dressing percentage. Control treatment (0.0%) had highest feed intake and best feed conversion ratio. The mortality rate was not affected significantly by the addition of garlic oil in broiler diet. The garlic oil inclusion reduced the mortality rate of the birds, increases productivity and food safety. The result showed on cost implication reveal the economical evaluation of the experiment diets indicated that, the diet with 0.3% level of garlic oil showed the highest profitability ratio as compared to the group. This might be due to the highest return of the weight gains recorded by this group of chicken.

Abstract This study aims to investigate the effects of commercial probiotic supplementation in water on the performance parameters, carcass traits, immune function, and antioxidant capacity of broiler chicks. In the experiment, 120 Arbor Acres (AA) broilers (60 male and 60 female) were randomly allocated into four groups (G) – G1: basal diet and G2, G3, and G4: basal diet with 1% Lactobacillus casei, 1% L. acidophilus, and 1% Bifidobacterium in the water, lasting 42 days. The experimental results revealed that probiotic additives produced positive impacts on body weight, average daily feed intake (ADFI), and average daily weight gain for female chicks, whereas these probiotics significantly reduced ADFI and the feed conversion ratio of male chicks (P < 0.05). Probiotics efficiently improved eviscerated yield and breast yield while reducing the abdominal fat (P < 0.05) for the male broiler chicks. A marked increase was observed in the weight of the spleen, bursa of Fabricius, and thymus in the treatment group (P < 0.05). Besides, probiotics produced a significant effect on the concentrations of immune-related proteins (P < 0.05) and markedly increased the concentrations of antioxidase and digestive enzymes when compared with the control (P < 0.05). The addition of probiotics dramatically reduced the total counts of Escherichia coli and Salmonella and increased the quantity of Lactobacilli (P < 0.05). The results of the present study demonstrated an increase in growth performance, carcass traits, immune function, gut microbial population, and antioxidant capacity by supplementing 1% probiotics (L. casei, L. acidophilus, and Bifidobacterium) in the water for broilers.

A 21-d investigation was conducted to ascertain the effect of 50% whole millet grain replacement for milled millet on growth performance, gastrointestinal conditions and development in broiler chickens. Eighty-four one-day-old unsexed broiler chicks were randomly allotted to two treatment groups with 7 replicates of 6 chicks per replicate. Two diets; whole millet diet (WM), consisting of 50% of the millet provided as whole grain, and the ground millet diet (GM), as the control, were formulated and fed ad-libitum throughout the study period. Performance data: feed intake, daily live weight gain and feed conversion ratio were recorded weekly, i.e. at 7, 14 and 21d, while gastrointestinal assessment: jejunal, digesta pH, relative weights of the proventriculus, gizzard, pancreas and liver, and jejunal and ileal morphometry were conducted on 21d. Similarities (p > 0.05) were observed in the growth performance, digesta pH and relative weight and length of duodenum, jejunum, ileum and caeca for chickens in both treatments. A 25.7% increase in gizzard weight was observed in chickens on WM, as well as significant (p < 0.05) increases in jejunal and ileal height and jejunal villus width were recorded on the chickens. A significant reduction in flock uniformity was observed in chickens fed the whole millet diet at 14d. It could therefore be concluded that 50% whole millet grain replacement for milled millet resulted in similar growth performance and improved gastrointestinal function and activity in 21-d post hatch chickens.

Background: The effect of a phyto-supplement (PS) composed of Aerva lanata, Piper betle, Cynodon dactylon and Piper nigrum on carcass characteristics was evaluated in commercial broiler chicken. Methods: A total of 192 day-old commercial broiler chicks were allocated to the four experimental groups and each group was separated into 6 replicates, with 8 birds per replicate. The dietary treatment groups were the positive control (basal diet + antibiotic, chlortetracycline @355g/ metric ton of feed), negative control (0% PS: basal diet only), 1% PS (basal diet +1% PS) and 2% PS (basal diet +2%PS). The trial lasted for 42 days (0 to 42 D of age). The carcass characteristics were recorded for two birds from each replicate at the end of the trial. Result: The broilers fed chlortetracycline and 1% PS recorded the highest (P=0.0205) and those fed only basal diet (negative control) recorded the lowest dressing percentage. Broilers fed diet supplemented with 1 and 2% PS exhibited higher (P less than 0.0001) weight and relative weight of lung than other treatments. Broilers fed diet supplemented with 1 and 2% PS exhibited lower weight (P=0.0032) and relative weight (P=0.0002) of liver when compared with the antibiotic treatment. Feeding 1% PS increased the relative weight of heart quadratically (P=0.044) while 2% PS reduced the weight of heart. Broilers on negative control diet recorded the highest weight (P=0.0002) and relative weight (P less than 0.0001) of kidney.

One hundred and fifty (150)day-old Abor acre broiler chicks were used for this experiment toassess growth performance and carcass characteristics of broilers fed processed roselle (Hibiscus sabdariffa) seed meal were investigated. The birds were randomly assigned to five dietary treatments with three replicates (ten chicks per replicate)each in a completely randomized design (CRD). In the feeding trial, raw roselle seed meal (R RSM), roasted roselle seed meal (R RSM), boiled roselle seed meal (BRSM) and soaked roselle seed meal (SRSM) were incorporated as part replacement for groundnut cake at 50% level of inclusion.Proximate composition of the processed test ingredients and the results showed that there were no significant (P>0.05) differences among the treatment means. Raw roselle seed meal (RaRSM) gave the least crude protein while the highest was recorded in boiled roselle seed meal (BRSM). Birds fed diet without roselle seed meal inclusion (control diet) had the best final body weight and feed conversion ratio but not significantly (P>0.05) different from other treatments.Birds in treatments 2 and 4 (RaRSMand BRSM) had the least survival rate (96.67%)while the rest treatments had 100%. Cut-up parts showed no significant (P>0.05) differences exceptfor the wings of the bird fed roasted roselle seedmeal was significantly (P<0.05) different and higher than those fed control, raw, boiled and soaked roselle seed meal (10.87, 7.52, 9.85 and 9.46%, respectively). Results from visceral organs showed no significant (P>0.05) differencesexceptproventriculus which exhibited significant (P<0.05) differences among the treatment means. Proventriculus of bird fed roasted roselle seedmeal (R RSM)was highest (0.80%)while those fed raw roselle seedmeal (R RSM) gave the least (0.50%). This study however, revealed that using processed (roasted, boiled and soaked) roselle (Hibiscus sabdariffa) seed meal as part replacement for groundnut cake has no deleterious effects onthe broilerchickens.

A study was conducted to determine the effect of different levels of okra (Abelmoschus esculentus L.) seed powder (OSP) in diets on performance, carcass characteristics, some blood parameters, and gut microbial populations in broiler chickens. For the present experiment, 216 day old chicks were randomly divided into four groups, each group consisting three replicates of 18 chicks in a completely randomized design. Four diets were formulated with diet 1 as the basal diet (control), while 2, 3, and 4 were supplemented with OSP at 1, 2 and 4 %, respectively. The results revealed that the highest final live body weight, accumulative weight gain, and better feed conversion ratio was achieved in birds fed with 1 or 2 % of OSP. Feed intake and carcass characteristics were similar among groups. The highest relative weight of the spleen and cecum was observed in the control group, while the lowest value was observed in birds fed with 4% and 2% OSP, respectively. The longest length of the gastrointestinal tract was seen in 2% OSP compared to other groups. Serum cholesterol and ALT activity were decreased as compared to control diets. The group fed with 2 % OSP showed higher albumin levels compared to those fed with 1% of OSP. The population of total bacteria and Escherichia coli in jejunum digesta of OSP supplemented broiler chickens was reduced, meanwhile, there was an increased in lactic acid bacteria counts as compared to control. Therefore, 1 and 2 % okra seed powder in the diet of broiler chickens was able to improve the growth performance.

Dietary Treatments

We investigated the effects of a blend of organic acids (OAs) and medium-chain fatty acids (MCFAs) supplementation in 800 1-d-old male Ross 308 broiler chickens (42 ± 0.90 g) in a 7-week study. Broiler chicks were randomly allocated into one of the five dietary treatments (16 birds per pen with 10 pens per treatment). Dietary treatments consisted of corn-soybean meal based basal diet and the basal diet supplemented with blend of OAs and MCFAs at 0.25, 0.5, 0.75 g, and 1 g per kg of feed. In the current study, during the whole experimental period, the inclusion of the blend of OAs and MCFAs in the basal diet linearly improved (p < 0.05) body weight gain (BWG), feed conversion ratio (FCR), and dry matter digestibility. The increasing inclusion of the blend of OA and MCFA levels in the diets linearly decreased (p = 0.002) feed intake during d 1 to 7. Broilers fed diets containing different levels of the blend of OAs and MCFAs showed a linear increase (p = 0.006) in Lactobacillus concentrations and decrease (p = 0.014) in ammonia (NH3) at the end of the experiment. However, the blend of OAs and MCFAs did not affect carcass quality, E. coli, and Salmonella counts, as well as hydrogen sulfide and total mercaptans gas emission (p > 0.05). In conclusion, the blend of OA and MCFA supplementation positively influenced growth performance, DM digestibility, excreta Lactobacillus counts, as well as NH3 gas emission in broiler chickens.

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.

Mannan Oligosaccharides

The study aimed to evaluate the use of β-mannanase and mannan oligosaccharides (MOS) to replace growth promoters in broiler diets. Four hundred male Cobb broiler chicks were used, with initial weight of 45±1g, distributed in a completely randomized design with five treatments and eight repetitions of ten birds. The treatments were: basal feed; basal feed without growth promoter; basal feed without growth promoter + β-mannanase; basal feed without growth promoter + MOS; and basal feed without growth promoter + β-mannanase + MOS. The feed intake of the birds increased in response to dietary treatments compared to basal diet during the period 1-21 days of age. A higher weight gain and improved feed conversion was found at 42 days of age among birds that had received the basal diet without growth promoter + MOS. The absolute weight at slaughter, relative carcass and prime cuts except breast weights improved in response to dietary treatments compared to the basal diet at 42 days of age. No difference was observed in relative weight of the liver, while significant differences were found in the weight of heart, gizzard, and abdominal fat. It was concluded that β-mannanase and MOS can replace the growth promoters in broiler diets without compromising production and economic performance. However, the association of these products into the feed may cause negative interaction that reduces the broiler chickens' performance

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.
