Breeding of large camelids

While the anatomical and physiological characteristics of the large camelids (dromedaries and Bactrian camels) have been widely commented by researchers, the modalities of its rearing (reproduction, lactation, feeding, fattening, sanitary and technico-economic management) in a context of "zootechnical modernization" are more rarely exposed. The present book attempts to provide a practical synthesis for all the new actors of this emerging sector.

Breeding of the Maraîchine breed beef cattle and meat quality

The breeding of local breeds with small or very small numbers of animals is currently attracting renewed interest because it is in line with agro-ecological issues and meets consumer aspirations. This article focuses on the Maraîchine cattle breed, which is currently used for meat production. Within the framework of a research-action project, researchers built a protocol with farmers to evaluate the nutritional and sensory quality of their beef. After presenting the context of the Maraîchine cow farm, the article presents the experimental design and the results obtained. Ten grass-finished beef cattle and 8 concentrate-finished beef cattle from 7 farms were recruited. The analyses were performed on flank steak and focused on the biochemical and metabolic characteristics of the muscle, sensory qualities and rheological properties, intramuscular lipid content and fatty acid composition, and finally, on the antioxidant potential of the meat. Meat is on average richer in polyunsaturated fatty acids and less rich in saturated fatty acids than other meat breeds. The grass finishing diet leads to leaner meats with a better health value. Antioxidant defenses are very high and grass-fed finishing mainly strengthens exogenous antioxidant defenses. Regarding sensory and rheological qualities, grass finishing does not affect the color of the meat but results in a less tender meat despite an increase in juiciness.

Quality prediction tools tested by French professionals

The beef industry is structured by two types of consumption: everyday purchases oriented towards economical products in tender portions, often processed (such as chopped steak) and pleasure purchases oriented towards a search for gustatory pleasure and the satisfaction of societal and environmental criteria.
However, it is difficult for the industry to guarantee regular and homogeneous products to satisfy consumers. These inadequacies stem from the current carcass grading systems. Thus, the professionals we met appear to be in favor of a change in the grading system based on a sensory quality prediction system that could be inspired by foreign systems such as "Meat Standards Australia" for butchered cuts. Such a system, through its segmentation, could meet the expectations of both types of consumption, daily and pleasure, allowing to generate an added value for the whole sector as it is the case in Australia. However, the diversity of organizations with sometimes divergent interests makes it very unlikely, in the short term, to set up a prediction system on a sector-wide scale. Thus, the implementation of a carcass prediction system would more likely be the result of an individual initiative. The links where an individual initiative is most likely are, on the one hand, mass distribution for which the triggering lever lies in the dissemination of knowledge and, on the other hand, meat companies independent of livestock farming that wish to ensure a regular and qualitative supply. In addition, economic, operational, political and knowledge barriers make it unlikely that a sensory quality prediction system for beef will be developed collectively or by the upstream sector. However, a low probability exists, depending on the perception of a possible socio-economic opportunity by an innovative organization or on the evolution of European regulations.

Beef production in Brazil and future prospects

With a strong growth in production and export over the last 20 years, Brazil continues to consolidate and strengthen its position in international beef markets. This article summarizes Brazil’s improvements and developments in this sector, tracing the evolution of the Brazilian beef market from 2000 to 2021, paying attention to quality indicators and changing consumer expectations. In addition, this article presents the challenges and prospects for the Brazilian beef sector and highlights including the positive economic, social, and technological developments resulting from the implementation of the Meat Standards Australia (MSA) grading scheme. Projections for the Brazilian and world beef market are based on Brazilian and international research reports. Although facing difficulties due to the economic and sanitary crisis, the forecasts for the Brazilian and international markets are promising. This is an opportunity for the Brazilian beef sector to demonstrate in a transparent way the reliability of its production processes, both at the farm level and at the processing level by meat companies.

The challenges of the Algerian beef sector facing a steady increase in consumption.

The book "The beef supply chain in Algeria" published by the publisher “L'Harmattan” describes the cattle farming systems, processing and distribution of beef in Algeria. It is organised in seven chapters related to the characteristics of the sector, imports of cattle and beef, producers and collectors of beef cattle, distributors, structures of consolidation and processing, weaknesses in the competitiveness of the sector and the perception of beef by the Algerian consumer.

The Dublin declaration of scientists on the societal role of livestock

The "Dublin Declaration" was initiated by the members of the Committee who organized the "International Summit on the Role of Meat in Society - What Science Says" which took place on 19 and 20 October 2022 in Dublin at Teagasc (the Irish Agriculture and Food Development Authority which provides integrated research, advisory and training services to the agriculture and food industry and rural communities). Animal breeding and meat production contribute to the health and well-being of animals and people, maintain ecological balances and guarantee socio-economic livelihoods, states this declaration, signed by around 220 scientists from all over the world. as of October 27, 2022.
