Impact of Aqueous Ocimum gratissimum (Lyn) Leaf Extract on Growth Performance, Gut pH and Bacterial Counts in Broiler Chickens

Abstract The study was carried out on one hundred and ninety-five day-old broiler chicks of cobb500 to study the effect of Ocimum gratissimum leaf extracts on growth performance, blood profile, microbial population in the faecal and gut samples. The chicks were randomly selected into five groups with thirty-nine chicks per group and each group replicated thrice. The groups were: control (synthetic antibiotics), extracts from 200 g fresh leaf, 400 g fresh leaf, 40 g air-dried leaf and 80 g aid-dried leaf per litre of water respectively. Data collected were subjected to one-way Analysis of Variance. The growth performance except mortality was similar (P>0.05) across the groups. Albumin, urea, cholesterol, alkaline phosphate and sodium were influenced (P<0.05) at the starter phase while only alkaline phosphate was significantly (P<0.05) highest in birds on 400 g of fresh leaf extract at the finisher phase. Neutrophil was highest (P<0.05) in birds on 400 g of fresh leaf extract while those on 200 g had higher values of lymphocytes and eosinophil at starter phase. At finisher phase, birds on antibiotics and 80 g of air-dried leaf extract had higher (P<0.05) white blood cell. Faecal total microbial population was least (<0.05) in birds on antibiotics and 200 g fresh Ocimum gratissimum leaf extract at starter phase. The study concluded that the adoption of Ocimum gratissimum leaf extract as prophylactic treatment against bacteria should be encouraged among poultry farmers.

Blood Profiles

This study was conducted to determine the effect of Ocimum gratissimum as a phytogenic feed additive (PFA) on growth performance, carcass, and blood profile of broiler chicken. One hundred and sixty day old broiler chickens were used for the study. Four diets were formulated to incorporate Ocimum gratissimum at 0, 50, 100 and 150 g per 100 kg of feed to form T1, T2, T3, and T4 respectively. The birds were divided into four groups of forty birds and each group was assigned one of the diets in a completely randomized design. Each group was further divided into four replicates of 10 birds each. Feed and water were supplied ad libitum and data collected were statistically analyzed. The result obtained showed significant (p<0.05) differences in the final weight gain (FWG), daily weight gain (DWG) and feed conversion ratio both at the starter and finisher phases. T4 had the highest significant (p<0.05) final weight gain (FWG), and daily weight gain (DWG) values. The lowest significant (p<0.05) feed conversion ratio (FCR) values were observed in T4. The feed intake of the birds was statistically similar (p>0.05) at both the starter and the finisher phases. Significant (p<0.05) increases were observed in dressed weight, dressing percentage, and cut-up parts (wing, thigh, drumstick, and breast) of the birds. T4 had the highest significant values for the carcass parameters. The haematological parameters analyzed showed significant (p<0.05) differences in the value for red blood cell (RBC), haemoglobin (Hb) and packed cell volume (PCV) values with T4 recording the highest significant (p<0.05) values for those parameters. All the serum biochemical parameters analyzed were not significantly affected (p>0.05) by the treatments. It can be concluded that Ocimum gratissimum could be added to broiler diet at 150 g/100kg as feed additive without any deleterious effect on the growth performance, carcass, and blood profiles of the birds.

Final Weight

The study was carried out to evaluate the performance of broiler chickens fed diets containing Ocimum gratissimum and Ocimum canum as an alternative to antibiotic growth promoters (AGPs). A total of 396, one day-old Cobb 500 broiler chicks were randomly allotted to six dietary treatments each replicated thrice with 22 birds per replicate in a completely randomized design. Six treatment diets were formulated containing 0g of experimental materials as control, 400 and 800g of O. gratissimum (T2 and T3), 400 and 800g of O. canum (T4 and T5) while oxytetracycline as recommended by the manufacturer was used as positive control. Data were collected on growth parameters: initial weight, final weight, weight gain, feed intake and feed cost per kg gain at both the starter and finisher phases. All data collected were subjected to analysis of variance and significant differences among treatment means were compared using Tukey procedures. Growth performance result showed that final weight, weight gain, feed conversion ratio and feed cost per kg gain were significantly higher (p<0.05) for birds fed diets containing O. gratissimum and O. canum at 800g per 100kg diets at both the starter and finisher phases. The population of Bacillus and Lactobacillus spp. were increased while the concentration of Escherichia coli, Clostridium spp., Salmonella spp., Enterobacteriaeae and Pseudomonas spp were significantly (p<0.05) reduced by the inclusion of Ocimum spp. Villi area, villi perimeter, height, width, crypt depth and villi height/crypt depth ratio were higher (p<0.05) for birds fed dietary supplement of 400g of O. gratissimum, 400g and 800g of O. canum and AGP (Oxyteracycline) than the control. Addition of O. gratissimum and O. canum in broiler chickens' diets significantly improved growth performance, intestinal microbiota and villi morphometric. Farmers and feed millers can use O. gratissimum and O. canum at 800g/100kg diets for improved 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.
