Estimation of growth parameters in Brahman cattle from Mexico
(2023)
The objectives were to evaluate non-linear models (NLM) to define the growth curve of Brahman cattle in Mexico. The database was derived from weight development control, with live weight measurements (150,932 in females and 286,804 in males) taken in the interval from birth to 1095 days of age. Four NLM were evaluated: Brody, Bertalanffy, Gompertz and Logistic. The selection of the NLM with the best adjustment was made based on the Akaike and Bayesian information criteria. Growth parameters were generated: adult ...

Investigating the efficacy of common agricultural practices for the management of fall armyworm (Spodoptera frugiperda (J.E. Smith)) on cereal crops
(2023-07)
In Benin, the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is the most important polyphagous noctuid pest. This study aimed to assess the impact of agricultural practices on the abundance of this pest and determine whether its feeding preference and larval development differ among four cereal types. First, we conducted a descriptive survey of 80 farmers randomly selected for farm visits and oral interviews using a structured questionnaire to ascertain their preferred agricultural practices ...

Land degradation and the upper hand of sustainable agricultural intensification in sub-Saharan Africa - A systematic review
(2024-05-13)
Sub-Saharan Africa (SSA) faces severe land degradation, driven by a combination of human and natural factors. Deforestation, inadequate land management practices, and unsustainable farming methods are the primary causes. The historical trends reveal the impact of soil erosion and nutrient depletion on 70% of the soil and 65% of its total land area. Unchecked degradation poses a critical threat to economic growth and poverty reduction initiatives. The region's food security is intricately linked to the complex interplay ...

Effect of storage conditions on soybean seed quality produced by smallholder farmers within two districts of Gauteng, South Africa
(2024-05-22)
Seed quality comprises of physical, physiological, and health attributes. Moreover, significant aspects of seed quality include seed viability and vigour. Maintaining good seed quality under sub-optimal storage conditions is one of the major challenges smallholder soybean farmers face. Hence, this study aimed to determine the effect of on-farm storage conditions on the seed quality of soybeans from smallholder farmers within the Gauteng Province, South Africa. The objectives of this study were to i) evaluate and ...

Association between metabolic and immunological changes during the transition period of dual-purpose cows in the Veracruz tropic, Mexico
(2023-12-30)
The objective of this study was to identify changes and associations in body condition score (BCS), serum glucose and β-hydroxybutyrate (BHB) concentrations, and white blood cell populations in dual-purpose cows during the transition period in the Veracruz tropic. BCS was evaluated and blood samples were taken weekly to determine white blood cell populations, serum glucose and BHB concentrations of 30 multiparous dual-cows (Bos taurus × Bos indicus) from 3 weeks before the expected date of calving to 3 weeks postpartum. ...

Determination of consumer milk price in the informal dairy market in Bangladesh: A district level analysis of vertical system linkage
(2023-12-30)
The objective of this study was to identify the determinants of consumer milk prices and test the hypothesis that input prices, e.g., rice straw and wheat bran, as well as the farmgate milk price exert an influence on the consumer milk price. A unique panel dataset from July 2018 to June 2021 was obtained from the Integrated Dairy Research Network (IDRN) Bangladesh Monthly Dairy Sector database and was analysed using the Generalized Methods of Moments (GMM) methodology. The data collection and validation were done ...

Effect of different levels of fluted pumpkin leaf (Telfairia occidentalis) in grower rabbit diets: Assessing growth parameters, haematological profiles, and serological responses
(2023-12-31)
The effect of fluted pumpkin leaf (FPL) on the growth performance, haematology, and serology of growing rabbits were examined. Seventy-five weaned rabbits of Dutch breed, with a mean weight of 513 g, and different sexes were allotted into 5 treatments with 3 replicates and each replicate housing five weaned rabbits. The five treatment diets were formulated to contain FPL at inclusion levels of 0 % (control), 30 %, 50 %, 70 % and 100 % in a completely randomized design. The animals were fed twice daily and given water ...

Evaluation of the breeding soundness test for Bonga sheep in the context of a community-based breeding programme in Ethiopia
(2023-12-29)
The aims of this study were to evaluate sire selection traits and semen characteristics for Bonga sheep. A total of 101 sires with different birth year from the Bonga sheep community based breeding programme (CBBP) were used to collect data. The data was analysed by using the GLM procedure of SAS and least square means was separated by using adjusted Tukey-Kramer method. The breeding soundness tests consisted of physical examinations, sire body condition score (BCS), scrotum circumference, estimated breeding value ...

Food security status and its determinants: A comparative study between farm households under government and non-government agricultural extension services in Bangladesh
(2024-02-29)
The ability to obtain food security is essential to human existence. Secure food access can have a variety of positive effects, such as economic expansion, the creation of jobs, and the eradication of poverty. This study assessed the food security status of farm households and its determinants in the Dinajpur district of Bangladesh. Efforts were also made to assess and compare the socio-economic demographics and item-wise calorie intake among households receiving government and non-government agricultural extension ...

Effect of different diets containing varying inclusion levels of Moringa oleifera leaf meal on growth, mineral composition and meat quality of the edible land snails Archachatina marginata and Achatina fulica
(2024-02-25)
This study examined the effect of different dietary inclusion levels of Moringa oleifera leaf meal on growth, haemolymph mineral composition and meat quality of Archachatina marginata and Achatina fulica. A total of one hundred and forty four (144) juvenile snails of A. marginata= 72 and A. fulica= 72, were used for the study. Eighteen (18) snails of each species were subjected to four dietary treatments (0%, 10%, 15% and 20%) of M. oleifera leaf meal in three replicates of six (6) snails per replicate over a period ...
