Effect of bio-char feed inclusion on milk yield and composition of HF crossbreed dairy cows at JUCAVM dairy farm

ABSTRACT This study was conducted to evaluate the effects of inclusion of bio-char on milk yield and composition of dairy cows in the JUCAVM dairy farm. Ten milk samples (in three day interval for 30 days) were collected separately and aseptically from all treatments. The General Linear Model (GLM) procedure of SAS version 9.2 were used to analyze milk yield and composition traits by using treatments and parity as fixed effect. The results showed that, milk yield was not significantly affecte...

Black soldier fly larval meal in feed enhances growth performance, carcass yield and meat quality of finishing pigs

Abstract: Using black soldier fly (BSF, Hermetia illucens) larvae as a novel protein source substituting fishmeal (FM) in animal feeds is globally gaining momentum. BSF can be reared on agro-industrial residues. However, incorporating BSF larval meal (BSFLM) into finisher pig diets has received inadequate attention. This study evaluated the effects of replacing dietary FM with BSFLM on growth, carcass traits and meat quality of finisher pigs. A control diet (including FM: 0% BSFLM) was compa...

Can black soldier fly Desmodium intortum larvae-based diets enhance the performance of Cobb500 broiler chickens and smallholder farmers' profit in Kenya?

Abstract: This study aimed to evaluate the performance of broiler chickens fed on 3 black soldier fly larvae (BSFL) (Hermetia illucens) and Greenleaf desmodium (Desmodium intortum)-based meals. We evaluated growth performance, carcass quality, and profitability under various commercial pathways (doorstep, retail, whole, and assorted). Desmodium and BSFL powders were formulated into 3 ratios: T1 25:75, T2 50:50, and T3 75:25. A commercial feed was used as a control. One hundred and twenty mix...

The data was gathered from 162 livestock farmers in six chiefdoms of the Koinadugu District. Quantitative data were collected using semi-structured questionnaires, while qualitative data was collected via personal observations, desk research, a...

Biosecurity Assessment of Layer Farms in Sierra Leone using Biocheck. UGent Scoring Tool

Abstract: Evaluation of the biosecurity of layer farms is essential for successfully controlling and preventing poultry diseases. The objective of this study is to evaluate the biosecurity of layer farms in Sierra Leone using the Biocheck. UGent scoring system. This online biosecurity evaluation tool assesses the farm's biosecurity compliance. The data was collected from 38 layer farms in four provinces and one area in the country. The data were encoded online to provide ratings for each farm...

Livestock farmers’ perception, perceived impacts, and adaptations to climate change in Koinadugu district, Sierra Leone

Climate change is having a negative influence on agriculture and livestock production systems. This study aims to assess livestock farmers’ perceptions and adaptive responses to climate change in the Koinadugu area of northern Sierra Leone. A sample of 126 livestock farmers was selected from four chiefdoms. The data were collected using a semi-structured questionnaire and meteorological time series data. The Statistical Package for Social Sciences (SPSS) version 23.0 and excel were used to ...

Analysis of Backyard Poultry Farmers' Awareness, Perceptions, and Adaptability to Climate Change in Tonkolili District, Sierra Leone

The poultry industry worldwide suffers significantly due to climate change, which may affect the chicken protein source. The study examined backyard poultry farmers' awareness, perceptions, and responses to climate change in Tonkolili, Sierra Leone. Data were collected from 232 backyard poultry farmers using a semi-structured questionnaire. The data were analyzed using SPSS 23.0 Software. According to the respondents' socioeconomic profiles, the majority of farmers (53.4%) were between the ag...

Impact of Heat Stress on Chicken Performance, Welfare, and Probable Mitigation Strategies

The poultry industry globally provides chicken meat and eggs, the most significant protein sources among animal foods. The industry is grappling with the effect of climate change which causes heat stress and harms the performance and welfare of the chicken. Heat stress has been the most significant environmental stress challenging the global poultry industry, as chickens only tolerate a narrow range of temperatures during heat stress. This review aims to assess the impact of heat stress on ch...

Analysis of the Awareness, Perception, and Adoption of Biosecurity Measures by Slaughterhouse Workers in Koinadugu District, Sierra Leone

Slaughterhouse workers are more susceptible to zoonotic disease infections from cuts and bloodletting, spreading blood-borne pathogens to societies. Adopting biosecurity measures by slaughterhouse workers in their daily tasks can lower the risk of spreading zoonotic diseases while improving food safety. This study aims to examine slaughterhouse workers' awareness of biosecurity, their perception of the efficiency of biosecurity measures in reducing zoonotic infections, and, most crucially, th...

OIL PRICE VOLATILITY AND INFLATION LEVEL IN NIGERIA: AN EXPONENTIAL GARCH APPROACH

Abstract Over the years, expenditures of public and private sectors are regulated by the activities in the oil and gas industry. The budget of Nigeria is hinged on the international price of crude oil and any shock on oil price affects the general activities in the country. With quarterly data from the period of 1981Q1 to 2020Q2, the study uses an exponential generalized autoregressive conditional heteroscedasticity approach to examine oil price volatility and inflation level in Nigeria. An ...

An Assessment of Some Production and Management Profile of Indigenous Chickens of Bekwarra Cross River State Nigeria

A study was conducted in Bekwarra, Cross River State-Nigeria, to assess the production and management profile of indigenous chickens. A total of 208 households were painstakingly sampled across seven administrative council wards of the local government. Data obtained were subjected to Statistical Package for Social Science (SPSS) analysis.
