“…The animal farming sector is increasingly criticised for excessive use of land, water and grains suitable for feeding humans [1], negatively impacting food security, as well as for greenhouse gas emissions contributing to climate change, overuse of antibiotics leading to the spread of antimicrobial resistance, and poor welfare of animals within the farming systems [2][3][4]. Studies with regenerative animal farming represent attempts to improve this scenario (e.g., [5]); however, there is uncertainty regarding the ability of such improvements to mitigate the situation.…”

Will the Cows and Chickens Come Home? Perspectives of Australian and Brazilian Beef and Poultry Farmers towards Diversification

Farmers across the world face criticism on environmental and animal welfare concerns, as well as are increasingly being affected by climate change. We explored the willingness of cattle and poultry producers in Australia and Brazil to consider alternative enterprises and diversification of their businesses. Twenty-seven farmers, 14 from Australia and 13 from Brazil, current or former beef or poultry producers, were interviewed to explore their perspectives about making such changes. The interviews were qualitatively analysed using Atlas.ti to generate key insights. Although the farmers were actively interested or had engaged in alternative enterprises, they recognised these presented a less certain future if they had been previously contracted to large companies. Some were critical of their respective governments and former contract companies for lack of assistance in finding suitable alternative enterprises. Farmers showed inconsistent recognition of the current challenges of animal production in relation to climate change. Our results indicate that most farmers are open to diversifying, but they face many challenges that have serious connotations. Public policies, knowledge transfer and a secure demand for alternative products emerged as major influential factors for Australian and Brazilian farmers in a fast and just transition from meat cattle and chicken raising to alternative activities.

“…In the Southern African Region, livestock constitutes over 60% of the region's total land area suitable for livestock farming. This contributes significantly to food security across the Southern African Development Community (SADC) region (Casey, 2021). Small scale variegated livestock farming, including ruminants and non-ruminants, has become popular in most developing countries .…”

Livestock including cattle, goats, sheep, pigs and poultry are kept under traditional farming systems producing manure, supporting crop production, insurance and financing emergency cash needs, and improving social status. The livestock feed resource base is mostly natural graze and crop residues whose quality and supply are dependent upon unreliable rainfall patterns. Due to rising demand for cropland, overgrazing, bush encroachment and bush burning, grazing supplies are being depleted. Grazing is supplemented using commercial feeds heavily infused with antibiotics contributing to antimicrobial resistance. Feed constitutes the largest expenditure, thus incorporating functional feed ingredients is favored. The study serves to increase farmers' awareness to substituting antimicrobials with functional feed ingredients. A systematic review of literature was done and keywords related to animal nutrition, functional feeds and antimicrobial resistance were used to identify relevant articles. Results revealed that functional feeding of livestock offers a potential diversity to animal production systems and may increase profitability in animal husbandry ventures. Functional feed ingredients improve productivity and vigor by enhancing digestibility, preserving and stabilizing beneficial gut microflora, and having a favorable impact on the environment. Probiotics, plant phytogenic compounds, and prebiotics, have the potential to replace antimicrobials as environmentally-friendly therapeutics and growth promoters.

“…In South Africa, livestock husbandry is the largest agricultural sector, accounting for more than 40% of agricultural production's total worth and occupying an estimated 80% of readily available agricultural land (Casey, 2021). In rural regions of South Africa, animal farming is often the main income generator and a major form of social capital.…”

“…In rural regions of South Africa, animal farming is often the main income generator and a major form of social capital. Although it can be said that primary agriculture contributes a relatively small share of the country's GDP; however, it plays a vital role in job creation and earning foreign exchange through exports (Casey, 2021). It should be noted that the major strength of South Africa's livestock production rest in its well-established private sector and its support for small and emerging commercial farmers.…”

Citrus is a well-known vital fruit grown in South Africa. The presence of important bio-nutrients and metabolites within the different Citrus fruits indicates their significant nutritional qualities. This study is aimed to evaluate the proximate and mineral components of whole Citrus limon and Citrus clementina while considering them as prospective feed material for livestock farmers in South Africa. The nutritional evaluation was done using standard analytical procedures of the Association of Official Analytical Chemists (AOAC). The mineral constituents of the whole citrus samples were analyzed using inductively coupled plasma optical emission spectroscopy (ICP-OES). From the result, the nutritional analysis showed that the whole C. limon contains significantly higher moisture content (14.13 ± 0.57) and fiber content (24.48 ± 0.61) than C. clementina (11.41 ± 1.24 and 20.66 ± 1.07). Meanwhile, C. clementina had a significantly higher protein value (8.65 ± 0.04) compared to C. limon (5.53 ± 0.10). Furthermore, the whole C. clementina had significantly higher K, Na, P, Zn, and Na+/K+ (1513.33 ± 16.99, 53.33 ± 4.71, 160.00 ± 0.00, 4.80 ± 0.00, and 1.09 ± 0.01) than the whole C. limon (1356.67 ± 20.55, 30.00 ± 0.00, 133.33±4.71, 1.67 ± 0.09, and 0.80 ± 0.02), respectively. While C. limon had significantly higher Ca, Mg, Mn, and Fe (593.33 ± 4.71, 160.00 ± 0.00, 1.00 ± 0.00, and 4.53 ± 0.25) compared to C. clementina (483.33 ± 4.71, 136.67 ± 4.71, 0.80 ± 1.11, and 3.43 ± 0.05). The study revealed variations in some nutritional and mineral components of whole C. limon and C. clementina; however, both citrus fruits have the potential to be explored for more significant livestock nutritional use in South Africa.
