Abstract

The aim of this study was to conduct a survey of poultry production systems and waste management in some local government areas of Anambra State of Nigeria. The basics of poultry farming were discussed including various types of chicken kept by farmers, production systems and scales. A proposal for improved poultry waste management through anaerobic digestion for biogas production was also discussed. The work highlighted anaerobic digestion process of poultry waste in biogas production. The research methodology adopted in the work is primary data obtained by use of questionnaires distributed to respondents, also secondary data obtained from journals and newspapers. The study revealed that medium scale poultry farms are predominant in the study area where majority of the farms still operate deep litter system. Only few of the farms operate battery cage system. It was found out that mechanized poultry farming is still at its lowest ebb in the state. It was found out that the poultry wastes generated by farmers are widely used for fertilizer. It is recommended that some level of mechanization is introduced in the industry to minimize the drudgery associated with poultry farming; technical training programs should be organized on regular basis to familiarize farmers with modern technology in poultry farming. Extension services are also recommended to educate farmers on recent best practices in the industry.

Abstract

This study meticulously examined the protein and carbohydrate contents in aqueous and chloroform extracts of Bombyx mori L. (silkworm) droppings from six distinct silkworm breeds (CSR2, CSR4, M43, M46, SK4 and Sanish 8) using standardized protocols. The findings consistently indicated heightened protein and carbohydrate levels in aqueous extracts across both 4th and 5thinstar droppings. Particularly noteworthy was the CSR4 breed, displaying the highest protein content at 10.76% and 8.09% in 4th and5th instar, respectively, while the M46 breed showcased the lowest protein content. Conversely, carbohydrate content peaked in the droppings of the M46 breed. This investigation underscores the indispensable role played by these constituents in soil health and agricultural practices, emphasizing their potential as organic fertilizers. It advocates for further comprehensive exploration of these elements to unlock their manifold applications beyond silk production. Recognizing their significance in sustainable agriculture and environmental management, this study prompts further research endeavors to harness their potential across various sectors.

Abstract

Microbial activity on food leads to its spoilage. This is usually by enzymatic processes that bring about lost of nutrients experienced on decaying food. Food decay, affect virtually all classes of nutrients in food especially, the organic aspect with proteins and lipids being the most. This study aimed at determinig the nutritional assessment and microbial safety of croaker fish from different frozen food centers. The nutritional assessment was determined through proximate analysis by standard method of AOAC and microbial safety by aerobic count, proteolytic and lipolytic count method using approprioate media. The results for proximate analysis showed moisture (62.38, 62.58 & 64.03), protein (23. 09, 23.40 & 22.98), lipid (10.21, 10.31 & 10.25), ash (1.11, 1.12 & 1.13) and carbohydrate (2.51, 2.65 & 1.61) for center A, B & C respectively. The mean values for aerobic plate count, proteolytic, and lipolytic counts were 7.30+0.18, 4.00+0.03, and 2.00+0.06, respectively, for center A, 6.31±0.29, 3.85±0.07, 2.61±0.01 for center B,and 7.70±0.82, 4.20±0.29, 2.82±0.13 for center Call in ×10³ CFU/ml. The presence of salmonella sp and straphylococcus were confirmed. These finding however, suggest contamination with aerobes with both proteolytic and lipolytic activities and particularly with pathogenic salmonella and straphylocaccus which could endanger the health of people upon their consumption.

Abstract

This research was aimed at evaluating the prevalence and molecular detection of Plasmodium falciparum from malaria diagnosed patients attending Mater Hospital. Venous blood samples (5ml) of 75 patients attending Mater Hospital were collected for preparation of thick blood firms for parasite screening and Nested PCR (nPCR) for Plasmodium falciparum (P. falciparum) gene detection. While thick film was prepared on microscopic slid, air dried, stained infield stain A and B.,and viewed under the light microscope with x100 objective lens, 10µl each of whole blood sample used for PCR Plasmodium falciparum gene detection using the nested Polymerase Chain Reaction (nPCR) as a diagnostic tool. The PCR products were analyzed in ethidium bromide stained 2% agarose gel. Microscopic examination of the stained blood film showed the presence of rig form trophozoites, schizonts and gametocytes of P. falciparum confirming high prevalence of malaria in Afikpo within the sampled population as 50 persons out of the 75 collected blood samples showed positive for malaria parasite. Age distribution of the samples shows that the most affected were those within the age brackets of 10 – 15 years with a prevalence rate of 26 (52%) followed by those within the age bracket of 16 – 21 years 11(22%). However, the nPCR analysis showed the presence of Plasmodium falciparum gene that resolved at 250bp and 270bp in all the 50 samples. Thereby indicating that Plasmodium falciparum was the prevalent specie that responsible for malaria in Afikpo. Following this result, it is recommended that PCR be included as part of the diagnostic tools for screening of the causative specie of malaria as this will go along way in ensuring effective treatment to prevent drug resistance.

Abstract

Considering the promising demand for water in agricultural practices and other applications, efficient use of water has emerged as a critical necessity. This study focuses on the estimation of weekly irrigation water requirements for major crops in the Chintakani major distributary of Nagarjuna Sagar project (NSP) over the period of 2015 to 2018. The methodology employed in this study involved the calculation of reference evapotranspiration using FAO Penmen-Monteith, which is a standard method for estimating evapotranspiration. The results revealed that the average irrigation requirements for Maize and Chillies during the rabi season were 483.12 mm and 898.95 mm respectively. To understand the water dynamics in this region, data pertaining to the weekly canal water during the years 2015-16 to 2017-18 was collected. This data was then used with the estimated demands of crops in the distributary command to assess the adequacy of water supply in meeting the irrigation needs. The analysis of this research revealed that the annual demands of crops during the years 2015-16 to 2017-18 were 1086880, 7956889, 8048374 mᶾ respectively. In contrast, the canal water supplies during the same period were 949440, 7891552.46, 6986024.89 mᶾ respectively. A key finding of this study was the identification of a severe water deficit during the years 2015-16 and 2017-18. This deficit was attributed to a lower amount of rainfall during these years, based on the agricultural practices and climatic variations of the region. This study underscores the urgent need for strategies aimed at enhancing the efficiency of water use in agriculture, particularly in regions prone to rainfall deficits.
