Comparison of linear discriminant analysis, support vector machine and artificial neural network in classifying Nigerian local turkeys based on plumage colours using biometric traits
(2022-10-18)
The ability of linear discriminant analysis (LDA), support vector machine (SVM), and artificial neural network (ANN) models to differentiate biometric traits of Nigerian local turkeys was investigated in this study. The biometric traits (bodyweight, body length, breast girth, thigh length, shank length, keel length, wing length, and wingspan) in 200 (20-week-old) turkeys were measured. Seventy percent of the datasets were used to train the three models, with the remaining 30% being used to test their performance. All ...

Characterisation of the lactation curve of Gyr and Sardo Negro cattle
(2023-07)
The objectives were to characterize the lactation curves (LC) of tropical Gyr and Sardo Negro (SN) cattle from Mexico for the design of breeding and management programs for these breeds. A total of 3561 records of 504 lactations and 3927 records of 449 lactations were used for Gyr and SN, respectively. Three lactation lengths (LL) were evaluated, namely 240 (240d), 270 (270d), and 300 (300d) days, with five non-linear models (NLM): Wood, Wiltmink, Cobby, Brody, and Sikka. Milk production was obtained at the beginning ...

Effect of Fermentation on the bioactive compound of cocoa Beans: a systematic review and meta-analysis approach
(2023-05-30)
Several studies have found the effect of cocoa bean fermentation on bioactive compounds through various fermentation characteristics; however, none of these studies adopted the meta-analysis approach. The effect of cocoa bean fermentation on six bioactive compounds: epicatechin, catechin, total phenolic content (TPC), anthocyanins, theobromine, and caffeine were systematically reviewed. This study aims to determine which variables that can affect the loss of bioactive compounds during fermentation so that their ...

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 ...

Partial purification of tannase enzyme produced by Bacillus licheniformis isolated from local soils
(2023-12-28)
Tannase is an enzyme that causes hydrolysis of a group of tannins (gallo-tannins) to gallic acid and glucose. This enzyme is of importance due to its numerous applications in many fields, such as in the food industry by enhancing tea and coffee flavour and improving the quality of fruit juices rich in tannins. Gallic acid is applied in the drug industry, and production of antioxidants is used in the oil industry. In this study, Tannase was produced by locally isolated Bacillus licheniformis using spent tea as substrate ...

Circular bioeconomy: Actors and dynamics of knowledge co-production in Finland
(2022-09-01)
The circular bioeconomy is a highly scrutinized concept in Finland and internationally, with a high degree of polarization regarding forest utilization rates and distrust between certain actors. This offers an interesting case for an exploratory analysis of issues associated with knowledge co-production. Knowledge co-production entails the integration of different knowledge types and collaboration across multiple societal actors with potentially conflicting viewpoints and agendas. We interviewed key organizations ...

Cooperatives as instruments of smallholder development: Evidence from banana, cocoa, coffee, and palm oil producers in Peru
(2023-11)
Collective action in the agricultural sector of Peru started in the form of agrarian production cooperatives around 1969. Following the collapse of the collectivisation program in the 1980s, external stakeholders helped to form marketing cooperatives in select sectors to discourage coca leaf production. Nowadays, cooperatives are only active in four sectors: banana, cocoa, coffee, and palm oil. Case study evidence of the performance of cooperatives in Peru is mixed, which raises the need for applied research to inform ...

Textile Waste Becomes Plastic Composites
(2023-09)
Every year, large quantities of textiles end up in landfills or in thermal recycling. However, some of this waste could also serve as raw materials for composite materials. Left-over cotton fibers of the textile industry, for example, are suitable as reinforcing fibers that enhance the mechanical properties of bio-based plastics. By using such waste streams, materials can be reinforced in a cost-effective and bio-based way in the future.

A scoping review on the presence of antibiotic residues in milk and the government strategies to control the use of antibiotics in milk industry in India
(2022-10-15)
In dairy farms, antibiotics are administered for therapeutic and prophylactic purposes. Lack of adherence to withdrawal periods and irrational use of antibiotics in the feed may lead to antibiotic residues (AR) in milk. Evidence suggests that the risk of AR in the milk is believed to be higher in developing countries due to multifarious reasons. The issue of residues in milk is predominantly concerning in India, as it has the largest consumer base in the world. Many studies have identified that consuming milk ...
