Effect of Garlic (Allium sativum) oil inclusion on Nutrient Retention and Caeca Microbial Population of Broiler Chickens

 This study was carried to evaluate the “Effect of Garlic (Allium sativum) oil inclusion on nutrient digestibility and caeca microbial population of broiler chickens”. A total of 180 one- day-old (Arbo acre) broiler chicks of mixed sex purchased from a reputable hatchery was used in this 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 garlic (Allum sativum) oil 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. Parameters measured covered nutrient retention and caeca microbial population. The results on nutrient digestibility showed a significant difference (P<0.05) among the treatments. Percentage digestibility of crude protein and crude fibre was significantly (P<0.05) higher in birds fed 0.3% of garlic oil.&nbsp

PRELIMINARY PHYTOCHEMICAL SCREENING OF BIOACTIVE CHEMICALS IN SUNFLOWER (Tithonia diversifolia) ROOTS

Plants are the most available sources of nutrients and phytochemicals; they have also played an important role in the development of drugs and treatment of various ailments in many countries. Therefore, this study was carried out to ascertain the preliminary phytochemical screening of bioactive chemicals in wild sunflower (Tithonia diversifolia) root. The solvents used for extraction includes: petroleum ether, methanol and distilled water. Results revealed that tannins, flavonoids, phenols, steroids, glycosides, carbohydrates and protein were present in the aqueous extract; only saponins were not detected in the sample. Methanol and petroleum ether follow similar pattern as tannins, flavonoids, phenols, steroids, glycosides, saponins carbohydrates and protein were all present in the sample. It was concluded that the extract contained several bioactive chemicals which could confer it the ability to have therapeutic or pharmacological effects on human and animals

PROXIMATE AND MINERAL COMPOSITION OF Pentadiplandra brazzeana STEM BARK

Plants are the cheapest and indispensable constituents of human diets supplying the body nutrients (carbohydrates, protein, fats, amino acids, vitamins) necessary for growth and body development. Therefore, this work was designed to examine the proximate and mineral composition of Pentadiplandra brazzeana stem bark (PBSB). Proximate composition of PBSB revealed the presence of 8.75 % moisture, 91.25 % dry matter, 6.43 % crude protein, 41.03 % crude fibre, 5.70 % ether extract, 12.11 % ash, 17.82 (g/100 g) carbohydrates, 0.47 % total reducing sugar and 632.2 Kj/100g energy respectively. Results on mineral analysis shows that PSSB is abundant in calcium (73.84 mg/100g) followed by phosphorus (41.55 mg/100g), magnesium (32.56 mg/100g), sodium (28.11 mg/100g), zinc (17.56 mg/100g), manganese (10.88 mg/100g), potassium (9.47 mg/100g) and copper (2.33 mg/100g). In order of mineral abundance in PBSB Ca ˃ phosphorus ˃ magnesium ˃ sodium ˃ zinc ˃ manganese ˃ potassium ˃ copper. It was concluded that PBSB is low in protein, energy and some minerals (copper and potassium)

Effect of Dietary supplementation of Garlic (Allium sativum) oil on the Growth Performance, Carcass Quality and Cost Implication of Broiler Chickens

This experiment was carried to evaluate the “Effect of dietary supplementation of Garlic (Allium sativum) oil on carcass quality, growth performance and cost implication of broiler chickens”. A total of 180 day–old- (Arboacre) broiler chicks of mixed sex was used in this 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) throughout the experimental period. The garlic oil (Allum sativum) was added to the basal diet at (0.00, 0.1, 0.2, 0.3%) level respectively. The treatments 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) higher body weight and best dressing percentage compared with the control treatment (0. 0%).Garlic oil inclusion reduced the mortality rate of the birds as well as productivity. The results on cost implication of the experiment diets indicated that, the diet with 0.3% level of garlic oil has the highest profitability ratio as compared to other treatment groups. This is be due to the higher weight gains recorded by the group of chicken
