ABSTRACT

The word 'unprecedented' is used liberally and often inappropriately. However, the current macro-economic and global political landscape is currently going through genuinely unprecedented flux. Economic recovery post-COVID-19 has driven strong inflationary pressures that are compounded by labor shortages and supply chain fragility. Global energy prices are extremely high, and many food staples are increasingly unaffordable for consumers. This article highlights the significance of using enzymes as feed additive to reduce feed costs.

ABSTRACT

The native chickens farming activities in Tomohon could support a provision of quality food continuously to the community, especially during the current covid-19 pandemic, but on the other hand various obstacles are still faced by small-scale farmers related to purchase price of feed and its availability. The empowerment of insects in animal feed could be an alternative solution. Based on this condition, a survey has been conducted in Tomohon City area which aimed to find out to what extent the using of insects as alternative feed applied in their livestock. This survey was conducted on thirty respondents in this area. Descriptive statistics were used in processing and presentation of data obtained in this survey. The responses of the respondent farmers were recorded in several points of view: time of experience in rearing chickens;experience in finding feed ingredients;farmer recognition on role of insect as animal feed;willingness to acquire skill improvement training. Concerning the time of experience in rearing chickens the most of respondents (70%) have an experience more than one year, 23% were between 6 months to one year, while the experience in finding feed ingredients: 47% of respondents (A1) informed easy to get it and 40% of respondent (A2) told that the ingredients were quite easy to get but the price increased. The farmer's recognition on role of insect as animal feed: 24% mentioned the insects in order of orthoptera, 21.2% described isoptera, 16,3% coleoptera, and then 14.4% informed the insects in diptera order as chicken feed. The respondents showed a different willingness to acquire training to improve their skill to use insect as alternative feed: 70% desired and 30% didn't thought the same thing. We concluded that the native chicken cultivation became interesting activities by the respondents in Tomohon to contribute the food, which is needed to improve their skill to use insect as alternative ingredient for their livestock chicken production improvement especially in the covid-19 situation.

Aquaculture: an introductory text ; 4(347), 2022.
Article in English | CAB Abstracts | ID: covidwho-1900772

ABSTRACT

This 4th edition covers issues associated with sustainable aquaculture development, culture systems, hatchery methods, nutrition and feeding of aquaculture species, reproductive strategies, harvesting, and many other topics. While its main focus is on the culture of fish, molluscs and crustaceans for food, the book also covers other forms of aquaculture, such as the production of seaweeds, recreational fish and ornamental species, as well as live foods, such as algae and rotifers that are used to feed larval shrimp and marine fish. Thoroughly updated and revised, this essential textbook now includes increased coverage of open-ocean cage culture and sea lice issues with salmon culture, coverage of the significant progress made in nutrition, including the move away from fishmeal as protein and fish oil as lipids in feed, information on biofloc technology uses, predictive impacts of climate change, probiotics, and the impact of COVID-19 on the aquaculture community, and updated aquaculture production statistics and lists of approved anaesthetics. Aquaculture remains one of the most rapidly growing agricultural disciplines, and this book remains an essential resource for all students of aquaculture and related disciplines.

ABSTRACT

The objective of this research was to investigate the behavior and conditions for CO2 adsorption using a mixture of CO2/N2 over a fixed-bed column of zeolite 5A. The study was performed with a variation in gas composition of CO2/N2 as a 20/80, 50/50, and 80/20 volume %, the adsorption temperatures as 298, 333, and 373 K and the total feed flow rates as 1, 2, and 4 L/h under 100 kPa pressure. The Bohart–Adams, Yoon–Nelson, and Thomas models were used to predict the breakthrough behavior of CO2 adsorption in a fixed column. Furthermore, the adsorption mechanism has been investigated using the kinetics adsorption of pseudo-first-order, pseudo-second-order, Boyd model, and intraparticle model. Increasing the CO2 composition of a gas mixture resulted in a high CO2 adsorption capacity because of the high partial pressure of CO2. The capacity of CO2 adsorption was decreased with increasing temperature because of physical adsorption with an exothermic reaction. The CO2 adsorption capacity was also decreased with increasing feed flow rates with inadequate time for CO2 adsorbates diffusion into the pores of the adsorbent before exiting the packed bed. The CO2 adsorption by zeolite 5A confirmed that the physical adsorption with intraparticle diffusion was the rate-controlling step of the whole process.

Assessing the impact of the COVID-19 pandemic on dairy cattle farming in Ethiopia|2021. v + 10 pp. ; 2021.
Article in English | CAB Abstracts | ID: covidwho-1777125

ABSTRACT

The purpose of this report was to document the immediate impact of the COVID-19 pandemic on dairy cattle farming in Ethiopia and draw recommendations for enhancing dairy farming and the dairy sector's resilience to such pandemics and other market shocks. It presents the results of a rapid survey of the impact of the COVID-19 pandemic on smallholder and medium-scale dairy cattle farmers in Ethiopia during the period between 5 September and 11 October 2020. A total of 1815 farmers who are part of the African Dairy Genetics Gains (ADGG) programme from five regions of Ethiopia, and one city administration participated in the study. Majority of the respondents reported that dairy farming input supply and service provision such as feed, veterinary services, animal vaccines, artificial insemination and daily hired labour had all decreased during the pandemic. More than half (60%) of the respondents reported a decrease in the total volume of milk produced per household, which was linked to the shortage of feed and other services. Forty-six percent of the respondents reported selling milk at a lower price compared to periods before the pandemic. Decreasing demand for milk by direct consumers, cooperatives and processors is one potential reason for the lower milk sales price. In conclusion, service providers and input suppliers (both government and private sector) working in collaboration with the Ministry of Agriculture are important in safeguarding farmers from shocks which result from man-made or natural disasters such as those brought about by the COVID-19 pandemic. Additionally, supporting dairy cooperatives and processors to produce at full capacity and linking dairy farmers to microfinance providers so they can access credit will ensure sustained profitability of their dairy farms.

ABSTRACT

Humpback whales (Megaptera novaeangliae) are cosmopolitan and highly migratory animals. They are found in all ocean basins and annually migrate between low-latitude waters, where they breed and calve during the winter and spring, and high-latitude waters, where they feed during the summer and autumn. Commercial whaling resulted in a considerable reduction in all humpback whale populations. In the Southern Hemisphere alone, more than 200,000 whales were caught. Most populations, including the Western South Atlantic Ocean Breeding Stock "A" (BSA), have shown signs of recovery after the International Whaling Commission (IWC) enacted a moratorium in the late 1960s.
