“…However, its use, among other effects, alters the physicochemical composition and fatty acid profile of the meat, not compromising the overall meat quality ( 105 , 106 ). On the other hand, the supplementation with guava ( P.guajava L.) agro-industrial by-products does not compromise the sensory characteristics of sheep meat if added in up to 30 to 40% ( 107 , 108 ). And still considering energy by-products, despite being rich in unsaturated fatty acids, canola grain did not influence instrumental analysis, centesimal composition, and sensory attributes of meat ( 109 ).…”

Technologies Used in Production Systems for Santa Inês Sheep: A Systematic Review

2022

This study identifies the number of publications that presented technologies used in the production systems of Santa Inês sheep in the last 5 years (2017–2021) carried out in Brazil. Therefore, the objective was to identify where we are in terms of knowledge about technologies in different fields (health, reproduction, animal breeding, behavior and welfare, nutrition and feeding, forage and pasture, carcass and meat quality, and economics and management of livestock systems). After rigorous selection, 114 studies were appointed and classified by knowledge field, and the main approaches within each theme were evaluated, pointing out research gaps. Most technologies have been in northeastern states. However, government agencies should develop public policies to disseminate techniques in rural areas because the production system in this region is still subsistence. This study highlighted the need for works that present management practices and tools that impact the improvement of animal welfare. Agro-industrial by-products have been widely used as an alternative for sheep feeding. However, economic feasibility analyses are recommended with these foodstuffs to substantiate their use as an option to reduce production costs. There is a lack of research allusive to the management of production systems, especially those related to estimates of economic feasibility indicators.

“…As a result, inclusion of 40% guava in diets (in place of corn) produced meat with satisfactory consumer acceptance in terms of color, yet with a less intense flavor, and tenderness. It was also observed that the animals suffered weight reduction (Costa et al 2019).…”

181negative correlation between the in vitro potential of many molecules and their ADME/T (absorption, distribution, metabolism, excretion/toxicity) profile is generally noted (Gleeson et al. 2011). Synthetic compounds present a significantly lower number of chiral centers and are both smaller and present greater flexibility, which results in weaker, less specific activity (Feher and Schmidt 2003). In contrast, plantderived natural products present a diversity of bioactive compounds with differing chemical scaffolds (Atanasov et al. 2015). Plant-derived products possess properties, such as binding affinities for specific proteins, that are evolutionary optimized (Appendino et al. 2010;Hunter 2008). Such characteristics make plant-derived products more advantageous for conducting ADME/T tests (Atanasov et al. 2015). Another advantage in drug discovery using medicinal plants is the known good correlation between ethnopharmacological information (well documented) and the medical use of the plant. Around 80% of identified compounds present some ethnomedicinal use, whether identical or related to current usage of the active plant elements (Fabricant and Farnsworth 2001). Further, technological advances in systems biology, bioinformatics, plant specialized metabolism, and synthetic biology present opportunities through which the medicinal properties of plants are discovered, utilized, and expanded toward developing new herb-inspired medicines (Li and Weng 2017). Accordingly, plant-derived natural products still represent a valuable source for drug discovery, this, motivated by global public health challenges, such as COVID-19, HIV/AIDS, malaria, hypertension, diabetes, and cancer (Thomford et al. 2018). About a quarter of all Food and Drug Administration (FDA)-and/or European Medical Agency (EMA)-approved drugs are plant-derived (Patridge et al. 2016;Thomford et al. 2018).In this context, Brazil possesses various biomes with a great portion of the world's biodiversity and approximately 20% of the plants and microorganisms on the planet (Calixto 2000). Among these biomes, the Cerrado is a neotropical savanna with rich flora (Klink and Machado 2005). Over 13,127 highly endemic plant species have been recorded within this biome (Myers et al. 2000;Overbeck et al. 2015;Silva and Bates 2002;Silveira et al. 2016). Yet, in regard to environmental conservation, only 41% of the original Cerrado still remains as native vegetation (Soares-Filho et al. 2014). This reduction is due to anthropogenic activities, such as monoculture, pasture expansions, mineral extraction, and the growth of urban areas (Faleiro et al. 2013). Considering only agricultural activity between 2002 and 2009, an estimated loss of 92,712 km 2 of natural Cerrado area has occurred (Overbeck et al. 2015). Preservation policies in Brazil need improvement, yet only 7% of the Cerrado is under legal protection (Soares-Filho et al. 2014).Both the bio-prospecting potential of the Cerrado for medicinal species and knowledge concerning traditional medicines are disappear...

“…This is the same change that occurs in the slaughter of old and malnourished animals, malnourished animals, sick animals, high stress of animals slaughtered at home, and violent treatment of animals before slaughter or harassment. Furthermore, recent research has discovered that food restriction has relatively little influence on meat quality characteristics (Table 1) (Baljić et al, 2019;Costa et al, 2020;Gali et al, 2020;Stahlke et al, 2019). Rational use of fuel and energy resources is one of the world's global problems today.…”

Energy-saving ventilation system for sheep premises to ensure food security and safety

et al. 2022

The impact of stress on an animal's physiological and behavioral state and the final meat quality has been extensively established. Prior to slaughter, animals are usually denied food and drink to reduce stomach content and minimize contamination from gut contents spilling from unintentional punctures to the gastrointestinal system during the eviscerating procedure. Feed withholding offers the benefit of lowering consumption of food as well as morbidity and death rates while in transit. Food restriction, on the other hand, triggers a stress reaction and causes animals to lose weight. In sheep farming, ventilation systems that functioned at temperatures above the threshold air temperature and relative humidity were very efficient and productive. The ventilation system proposed here works by using soil warmth, i.e., a renewable source of energy, and contributes to environmental protection. The results of theoretical and experimental studies of an energy-saving ventilation system using soil heat are presented. The use of an energy-saving ventilation system reduces energy and labor costs for creating a microclimate in sheep premises. The device of an energy-saving ventilation system is protected by the patent of RK KZ 26930 dated 15.07.2016.
