Sabina Alatari Ngodigha — 2024-05-31

Orashi River is one of the major rivers that drain the River Niger through the Niger Delta into the Atlantic Ocean. The relationship between the physio-chemical properties of the river water and benthic macro invertebrates were studied between October 2017 and September 2018. Monthly samples of the river surface water and macro invertebrates were collected at five sampling stations using standard methods. Means and standard deviation of the water parameters were determined and correlated with the macro benthos to determine their relationship.Oligochaeta was represented by 9 species; Crustacea had 3 species while 2 species were identified under Insecta. Temperature (0C) ranged between 27 0C and 29.40C. Conductivity fluctuated between 18 – 48.4μS/cm and pH was from 6.10 – 7.96. Salinity and turbidity ranged between and 0 – 0.02 and 8.50 – 107.7 NTU respectively. Total dissolved Solids (TDS) was from10 – 25.18 mg/L, Biological oxygen demand (BOD) 6.01 – 7.88 mg/l, Chloride 1.05 – 6.42mg/l, total alkalinity 3 – 9 mg/l and total hardness 2.29 – 9.93 mg/l. Nitrate, sulphate, Chromium, Iron and Zinc were between 0.05 – 0.95 mg/l, 2.10 – 10.31 mg/l, 0.003 – 0.08 mg/l, 1.542-4.966mg/l and 0.003-0.338 respectively. Correlation between macro benthos was positive with sulphate and DO but negative with Zinc, turbidity and BOD.There is need for effective monitoring of the river system to be able to detect environmental changes that could be corrected for a sustainable ecosystem.

ANTIBACTERIAL PROPERTIES OF CARICAPAPAYA (PAWPAW) LEAF EXTRACT ON SOME PATHOGENIC BACTERIA OF PUBLIC HEALTH IMPORTANCE

Esther Benafagha Enaregha — 2024-12-09

This study investigated the antibacterial activity of Carica papaya leaf extracts against pathogenic bacteria, aiming to explore the potential of natural remedies in combating bacterial infections. The rising global concern of antibiotic resistance necessitates the exploration of alternative therapeutic options. Carica papaya leaves, known for their traditional medicinal use contain bioactive compounds with potential antimicrobial properties. The study employed in vitro assays to assess the antibacterial effects of Carica papaya leaf extracts against a range of pathogenic bacteria, both Gram-positive and Gram-negative. The assays revealed substantial
zones of inhibition, indicating the ability of the extracts to impede bacterial growth. Minimum inhibitory concentration (MIC) values further underscored the potency of the extracts. These findings align with earlier studies identifying alkaloids, flavonoids, and phenolic compounds in Carica papaya leaves with antibacterial attributes. However, challenges such as variability in bioactive compound composition and lack of in vivo data warrant further research. Mechanistic studies, clinical trials, formulation development, and safety assessments are recommended to advance the understanding and potential application of Carica papaya leaf extracts as an alternative antibacterial treatment. Integrating traditional knowledge with modern scientific methodologies holds the promise of addressing the pressing issue of antibiotic resistance.

GROWTH PERFORMANCE AND ECONOMICS OF PRODUCTION OF WEANER PIGS FED GRADED LEVELS OF PLANTAIN PEEL MEAL SUPPLEMENTED WITH CORN PAP CHAFF

P.B. Omu — 2024-12-09

This research was carried out to investigate the effect of graded levels of plantain peel meal supplemented with corn pap chaff on the growth performance and economics of production of weaner pigs. Plantain (Musa paradisiaca) is a fruit crop which produces about 30-40% peels in the form of agricultural by-products (wastes). These peels (ripe and unripe) have been harnessed as animal feed or feed ingredients.Twenty-four (24) weaner pigs of either sex of the large white hybrids were procured froma reputable farmin Yenagoa, Bayelsa State. The weaner pigs which weighed 4-5kg initial body live weight were distributed into four (4) treatments of six (6) pigs per treatment and replicated three times with two (2) weaner pigs per replicate in a completely randomized design (CRD). The plantain peel meal was served at 45kg, 30kg, 15kg and 0kg in T1(Control), T2, T3 and T4 respectively.Corn pap chaff was served to supplement
the pig’s ration.Proper farm management practices and routine medications and vaccinations were strictly observed. Cool water and feed were supplied ad libitum. The experiment lasted for eighty-four (84) days. All data was subjected to a one-way analysis of variance (ANOVA). Under growth performance indices, the parameters measured were the initial weight, final weightand feed intake. The weight gain, feed conversion ratio and mortality were calculated. Results on performance indicate that T2 and T3 were significantly (P<0.05) better in final live weight, feed intake and feed conversion ratio; while feed intake increased linearly from T3-T4. The economics of production shows that the cost of production for all the treatment groups were similar; as there were no significant (P>0.05) differences in the total cost of production. It was therefore concluded that weaner pigs can be fed between 15% and 30% graded levels of plantain peel meal (PPM) supplemented with corn chaff without causing any deleterious effects on the performance and economics of production.
