The aim of the present study was to assess the effect of adding different turmeric amounts to sorghum-based diets for Japanese quails on animal performance, animal metabolism, yolk colour, egg quality, blood and liver biochemical parameters and sensory attributes of the eggs. The study included 210 egg-laying quails aged 50 days and lasted for 90 days. The study had a completely randomised design with six treatments and five replicates with seven birds per replicate. A control corn-based feed and sorghum-based feeds to which different turmeric levels were added (0%, 0.5%, 1.0%, 1.5% and 2%) were tested. The results showed that the sorghum-based feeds with added turmeric levels did not affect animal performance, metabolisation of protein and ether extract, internal and external quality of eggs, serum biochemical profile, including calcium, phosphorous, protein and liver transaminase enzymes. Blood cholesterol and triglyceride levels decreased when !0.5% percentages of turmeric were added to the feed. Yolk colour of the treatments differed significantly from that of the control, but the yolks were considered well suited for consumption. Turmeric reduced the cholesterol and triglyceride levels in egg-laying quails.

“…Also, when broiler chickens were fed with 1% activated biochar the useful fatty acid, oleic acid and total mineral content of the meat increased significantly (Park & Kim, 2001). Other trials with 2% biochar or a mixture of bamboo biochar and wood vinegar did not show significant differences in meat quality compared to controls (Sung et al, 2006; Fanchiotti et al, 2010; Ruttanawut, 2014).…”

Biochar, that is, carbonized biomass similar to charcoal, has been used in acute medical treatment of animals for many centuries. Since 2010, livestock farmers increasingly use biochar as a regular feed supplement to improve animal health, increase nutrient intake efficiency and thus productivity. As biochar gets enriched with nitrogen-rich organic compounds during the digestion process, the excreted biochar-manure becomes a more valuable organic fertilizer causing lower nutrient losses and greenhouse gas emissions during storage and soil application. Scientists only recently started to investigate the mechanisms of biochar in the different stages of animal digestion and thus most published results on biochar feeding are based so far on empirical studies. This review summarizes the state of knowledge up to the year 2019 by evaluating 112 relevant scientific publications on the topic to derive initial insights, discuss potential mechanisms behind observations and identify important knowledge gaps and future research needs. The literature analysis shows that in most studies and for all investigated farm animal species, positive effects on different parameters such as toxin adsorption, digestion, blood values, feed efficiency, meat quality and/or greenhouse gas emissions could be found when biochar was added to feed. A considerable number of studies provided statistically non-significant results, though tendencies were mostly positive. Rare negative effects were identified in regard to the immobilization of liposoluble feed ingredients (e.g., vitamin E or Carotenoids) which may limit long-term biochar feeding. We found that most of the studies did not systematically investigate biochar properties (which may vastly differ) and dosage, which is a major drawback for generalizing results. Our review demonstrates that the use of biochar as a feed additive has the potential to improve animal health, feed efficiency and livestock housing climate, to reduce nutrient losses and greenhouse gas emissions, and to increase the soil organic matter content and thus soil fertility when eventually applied to soil. In combination with other good practices, co-feeding of biochar may thus have the potential to improve the sustainability of animal husbandry. However, more systematic multi-disciplinary research is definitely needed to arrive at generalizable recommendations.

“…Dentre as pesquisas realizadas destaca-se a inclusão dietética das cinzas de carvão vegetal (FANCHIOTTI et al, 2010), minerais e probióticos (OBA et al, 2005), fontes de óleo (MURATA et al, 2003;COSTA et al, 2008), matérias primas da ração (KOVACS et al, 2000) e até fármacos (MORI et al, 2000). Entretanto os resultados são controversos devido à complexa interação entre os balanços de colesterol endógeno e dietético que são excretados pelo intestino, reciclados ou destinados à deposição na gema do ovo.…”

RESUMODurante décadas o colesterol foi associado a doenças vasculares e cardiopatias, sendo por inúmeras vezes contraindicado o seu consumo, e consequentemente o ovo. Visando impulsionar o aumento no consumo per capita de ovos, inúmeras pesquisas foram conduzidas com o objetivo de reduzir a concentração de colesterol na gema do ovo de poedeiras comerciais, a partir de manipulações dietéticas de galinhas e codornas. Os resultados obtidos se mostraram eficientes em diversas estratégias tais como carvão vegetal, fontes de óleos, compostos fenólicos etc. Entretanto, mecanismos fisiológicos adaptativos impedem que as aves mantenham as concentrações de colesterol reduzidas permanentemente. Objetivou-se com esta revisão discutir resultados de protocolos científicos conduzidos para reduzir a concentração de colesterol na gema do ovo de poedeiras.Palavras chave: Colesterol; Qualidade do ovo; Galinhas poedeiras; Carvão vegetal; Gema. ABSTRACTFor decades, cholesterol has been associated with vascular diseases and heart diseases, and its intake, and consequently the egg, has been contraindicated for many times. Aiming to boost the increase in per capita egg intake, researches were conducted with the objective of reducing the cholesterol concentration in the egg yolk of commercial laying hens, from dietary changes of chickens and quails. The results obtained were efficient in several strategies such as charcoal, sources of oils, phenolic compounds, etc. However, adaptive physiological mechanisms prevent birds from maintaining cholesterol concentrations permanently reduced. The objective of this review was to discuss the results of scientific protocols conducted to reduce the cholesterol concentration in the egg yolk of laying hens. Keywords:Cholesterol; Egg quality; Laying hens; Vegetal charcoal; Yolk. IntroduçãoO ovo é um alimento de elevado valor biológico, devido a sua inigualável composição bromatológica, onde estão balanceados nutrientes essenciais, com destaque para os aminoácidos, vitaminas lipossolúveis, lipídeos e minerais. Segundo Oba et al. (2005) a fração lipídica do ovo corresponde a 33 % do peso da gema, sendo seus principais componentes os triglicerídeos, os fosfolipídeos, os ácidos graxos livres e o colesterol. Este último tem recebido atenção particular por parte da comunidade científica devido à sua importância na saúde coletiva por ser associado
