Phenotypic Characterization of West African Short Horn (WASH) Cattle and their Crosses in Tolon District

This study aimed at characterizing the WASH cattle and their crosses reared semi-intensively in the Tolon District of Northern Ghana.  The age, colour and twelve (12) different biometric traits were measured on 125 cattle and subjected to Chi- square and principal component factor analysis.  WASH cattle were characterized by five different colour patterns; black, white, brown, fawn and black and white. The paired coloured pattern (black and white) was the most observed among the cattle.  G...

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...

Bioinformatic Analysis of Insulin-Like Growth Factor I Gene of Three Avain Species

ABSTRACT  A lot of attention has been paid to the study of Insulin-like Growth factor 1 (IGF1) due to its function in stimulating systemic body growth and regulating cell growth and development. A bioinformatics study was carried out to investigate the Insulin-like Growth Factor 1 gene of turkey, chicken and quail. A total of 15 insulin-like growth factor 1 nucleotide sequence and their corresponding protein were obtained from the Genebank (a public domain protein database) and were analyzed...

Growth and Haematological Response of Growing Rabbits to Diets Containing Graded Levels of Sun Dried Bovine Rumen Content

ABSTRACT  The growth and haematological response of growing rabbits to diets containing graded levels of sun dried bovine rumen content (SBRC) were studied. Five diets containing 0 (control), 10, 20, 30 and 40 % sun dried bovine rumen content coded as T1,T2,T3,T4 and T5, respectively, were compared. Twenty growing rabbits were randomly assigned to the treatments; each treatment had four experimental units. The rabbits were fed and watered ad libitum. The parameters measured were feed consump...

Genetic Diversity of Five Populations of the Nigerian Local Breeds of Goat Using Random Amplified Polymorphic Dna (Rapd) Markers

ABSTRACTS Genetic diversity and genetic distance of five populations of the Nigerian breeds of goat were investigated using random amplified polymorphic DNA markers. Five breeds of goat were used for the study and each breed constituted a population, hence, the five populations considered in the study. The populations were: Sokoto Red (SR), Sahel (SH), Kano Brown (KB), Bornu White (BW) and West African Dwarf (WAD) goats. The experiment was conducted within four geographical zones of Nigeria: ...

Physiological Response of Broiler Birds to Oral Supplementation with Aloe Vera and Neem Leave Extracts

ABSTRACT Two hundred and forty 14-day old broiler birds were used in a study conducted to investigate the physiological response of boiler birds to oral supplementation with aloe vera gel and neem leaf extracts. In experiment one, one hundred and twenty 14- day old broilers were used to assess the physiological response of the broiler birds to oral supplementation with alovera gel extract, while in experiment two, one hundred and twenty 14- day old broilers were used to assess the physiologic...

Performance, Egg Quality Characteristics and Serum Biochemistry of Laying Birds Fed Diet Containing Neem Leaf Meal

ABSTRACT A study was conducted with 300 “Bachelor” Brown laying birds to determine the performance, egg quality characteristics and serum biochemistry of laying birds fed diets containing neem leaf meal. The birds were randomly selected at nineteenth week of age into five treatment groups with three replicates per treatment with each replicate containing twenty birds. The experiment was laid out in a completely randomized design (CRD). Five isocaloric and isonitrogenous diets designated a...

Effects of Difference Timing of Routine Vaccination Schedules on Growth Performance, Mortality Rate and Blood Parameters of Broilers.

ABSTRACT This study was conducted to find the effect of the delayed routine vaccination schedules on growth performance, blood parameters and immunity levels of broilers reared in a humid tropical part of Nigeria. A total of 90 broiler chickens were procured and sorted into three treatments (control, 1 week delay in vaccination and 2 weeks delay in vaccination). The results showed significant differences (P < 0.05) in all growth parameters studied with lower values for broilers with delayed v...

Improvement in Egg Production Traits in the Light Local Chicken Ecotype Using a Selection Index

ABSTRACT Fifty hens and five cocks from a random mating population of light local chicken ecotype (LLCE) were mated and the fertile eggs hatched to obtain the parent generation (G0) used for this study aimed at improving egg production traits in the LLCE using a selection index. The hens were monitored for short-term (90-days from first day of lay) egg production traits namely: Body Weight at First Egg (BWFE), Average Egg Weight (AEW) and Total Egg Number (TEN). Data obtained were subjected t...

Semen Quality and Haematological Characteristics of Exotic and Crossbred Boars Exposed to Different Durations of Thermal Stress in the Humid Tropics

ABSTRACT This study was conducted to investigate the effect of 45 and 60 minutes of exposure of crossbred (LW x Local) and exotic (LW) boars to tropical solar radiation on their body temperature pattern, libido, semen quality and haematological profile. 12 LW x Local and 12 LW boars of 10 months old were used for the experiment. The experiment was carried out in the Piggery Unit of the Department of Animal Science Farm, University of Nigeria, Nsukka for a period of eight weeks (4 weeks for th...
