“…Various types of lipids, including glycerides, fatty acids, waxes, and phospholipids have been investigated due to their ability to encapsulate active food ingredients. Lipids have been used to encapsulate nitrogenous compounds such as urea with fat or bees wax (Carvalho et al, 2019), arginine with fatty acids (Meyer et al, 2018), and Lysine with a lipid mix (Prandini et al, 2013).…”

The expected population growth will increase global food consumption, particularly meat consumption, which is estimated to increase 14% by 2030. Hence, the efficient utilization of all the resources involved in meat production, predominantly feed additives in livestock, is important due to economic costs and the high environmental in terms of gas production and ammonia excretion. Efforts have been made to increase efficiency in livestock production and improve the absorption and utilization of nutrients. Nevertheless, advances in technology in the chemical, pharmaceutical, and food industries have barely been used by the livestock and poultry industry. The micro/nano encapsulation process has been used in animal nutrition to protect bioactive compounds or to control the release of feed additives into the animal gastrointestinal tract, avoiding rumen microbes attack, or monogastric digestion in swine and poultry, to be available in the small intestine. However, not all the encapsulation techniques are suitable for applications in animal feeding. For example, spray drying, emulsion and coacervation can be used to control the release of feed additives in ruminants. In this sense, micro encapsulation of different feed additives such as amino acids, fatty acids, and probiotics may face enormous challenges to help improve livestock and poultry nutrition. The objective of this review is to highlight and discuss the techniques, compounds, and key aspects involved in the encapsulation of feed additives and nutrients with potential applications in the livestock and poultry production

“…Thus, extruded urea (EU, Amireia 200S), the end product of the extrusion process of corn starch, livestock urea and sulfur, is a plausible alternative to be used in animal production (Ítavo et al, 2016), and reduce the risks caused by livestock urea. This product provides NNP, highly available energy and sulfur for the synthesis of sulfur amino acids, in addition to presenting a slow release that prevents ammonia intoxication and provides a synchronism between protein and energy, optimizing the synthesis of microbial protein of high biological value (Carvalho et al, 2019).…”

The objective of this study was to evaluate the influence of increasing levels of extruded urea (EU, Amireia®) in the diet of lambs naturally infected by gastrointestinal nematodes on the interactions in the host-pasture-soil components in edaphoclimatic conditions of the tropical rainy savanna. 60 Texel lambs with a mean initial weight of 20.7±0.87 and mean age of 2.5±0.70 months were distributed in a completely randomized design, in five treatments consisting of different levels: 0; 6; 12; 18 and 24 grams g 100 kg-1 live weight (LW) of EU in the supplement of lambs in Brachiaria spp. The performance of lambs, parasitological variables, gastrointestinal nematodes (NGIs), and larvae recovery in pasture and soil were evaluated. The highest animal performance was observed in animals that received 0 to 18 g kg-1 LW (146.0 g day-1) and the lowest in animals supplemented with 24 g kg-1 LW (81.0 g day-1 ) of EU. The body condition score (BCS) was similar in the animals (P>0.05). Parasitic infection did not differ as a function of EU level (P>0.05). Eggs of Haemonchus spp., Trichostrongylus spp., Cooperia spp., and Oesophagostomum spp were found. The largest amount of larvae in the L1/L2 and L3 stages was recovered in the pastures occupied by the animals that received supplementation 0 g kg-1 LW of EU (750 larvae), the smallest in those that the animals received 6 g 100 kg-1 LW of EU (54 larvae). The presence of larvae in the L1/L2 stages changed significantly (P<0.05) in the soil, in the other stages it did not differ in the soil. Increasing levels of extruded urea do not influence the eggs per gram of feces (EPG) count. The 0 to 18 g 100 kg-1 LW level maintains animal performance, BCS and FAMACHA©. There is less dispersal of NGI larvae in pasture and soil when EU levels increase in the edaphoclimatic conditions of the rainy tropical savannah.
