“…As forragens geralmente não fornecem os minerais na quantidade ideal para que as necessidades dos animais possam ser atingidas por isso, rebanhos que não são suplementados adequadamente com as misturas minerais poderão desenvolver doenças carenciais com prejuízo no crescimento, mantença e nas fases reprodutivas (KHAN et al, 2010;SUTTLE, 2010).…”

“…As deficiências minerais são muito comuns, principalmente quando os animais são criados em condições de pastejo, o que limita a produção (KHAN et al, 2010). A maioria das deficiências ou desbalanços não se manifestam clinicamente, mas podem causar perdas em índices produtivos, mesmo em níveis subclínicos, Figura 2.…”

“…No parto, a concentração de Fe foi maior nos cordeiros cujas mães eram do grupo controle, enquanto os outros minerais apresentaram concentrações semelhantes entre os grupos. Os cordeiros também foram avaliados quando estavam com 1 mês de idade e os nascidos das ovelhas do grupo experimental tiveram maiores concentrações de ferro e cobre no plasma, porém houve uma redução na concentração de zinco.Os autores concluíram que o aumento da concentração de cobre e ferro durante as primeiras semanas de idade pode resultar em deficiências de zinco Khan et al (2010). realizaram um experimento com 30 ovelhas da raça Kajli de 3 anos de idade e de aproximadamente 36kg, separadas em fêmeas lactantes, secas e machos.…”

A ovinocultura é uma atividade que vem crescendo nos últimos anos, porém na literatura são poucas as pesquisas que reúnem dados sanguíneos e que reúnem dados sobre a mineralização destes animais, tanto com minerais orgânicos e quelatados. Baseado nisso foi feito um levantamento com os trabalhos mais atuais sobre mineralização, balanço energético negativo e estudo de perfil metabólico de animais em diferentes fases reprodutivas e produtivas desta espécie, o que originou esta revisão da literatura.

“…Animal productivity is influenced by nutritional status. Therefore, the provided animal feed should be diverse and supplemented with non-traditional additives to enhance its nutritional value and emphasize its vital role in improving productivity, as well as enhancing the health and immunity of the animals (Steen et al, 2008;Khan et al, 2010).…”

This study was conducted in the Department of Animal Production, College of Agriculture, University of Tikrit, to study the impact of treatment with Coenzyme Q10 and Zinc Methionine on some blood biochemical parameters in Awassi lambs. A total of 20 Awassi lambs, aged between 4 and 4.5 months, with an average weight of 21.71 ± 0.34 kg, were utilized and randomly assigned to five treatment groups. The first group received distilled water, while the second and third groups were administered Coenzyme Q10 at doses of 25 and 50 mg per 5 ml of water per animal, respectively. The fourth and fifth groups received a combination of Coenzyme Q10 and Zinc Methionine at doses of (25 mg of Q10/ 5 ml of water/animal + 100 mg of zinc/ animal) and (50 mg of Q10/5 ml of water/animal + 100 mg of zinc/animal), respectively. The results of this study revealed significant (P ≤ 0.05) increases in the levels of total proteins and albumin in the blood of animals in the fifth, fourth, and third treatment groups compared to the first and second groups. Moreover, a significant increase in globulin levels was observed in the fifth and third treatment groups compared to the other groups 90 days after treatment. Additionally, there was a significant (P ≤ 0.05) decrease in the total cholesterol level in the blood serum of animals in the fifth treatment group compared to the other groups. Furthermore, there was a significant (P ≤ 0.05) reduction in the levels of triglycerides and very low-density lipoprotein cholesterol, as well as a significant reduction in atherogenic index in the treated animals compared to the control group. Additionally, there was a significant (P ≤ 0.05) decrease in low-density lipoprotein cholesterol levels in the blood serum of animals in the fifth and fourth treatment groups compared to the control group, while high-density lipoprotein cholesterol levels showed a significant increase in the fifth and fourth treatment groups compared to the control group after 90 days of treatment.

“…Imbalances of Se may be due to low amounts of minerals in soil as well as in forages, which is the main diet of grazing animals (Khan et al 2010). Although in Brazil there are few studies of this kind, there are indications of low Se intake in production animal diets (Reis et al 2009), and evidence of Se deficiency in some soils of Brazil were presented by Sillanpää and Jansson (1992).…”

In Brazil the total area of native and cultivated pasture used for livestock is around 180 million hectares, and selenium (Se) is absent from mineral fertilizer formulas. Nutritional supplementation of this element takes place along with provision of mineral salts in the form of sodium selenite. In the present work, the effects of adding selenate and selenite on Se biofortification, antioxidant activity and anatomy alterations in Brachiaria brizantha were evaluated. The experiments were disposed in a completely randomized design in a 6 × 2 factorial scheme, by means of five levels of Se (0; 0.5; 1.0; 3.0 and 6.0 mg/kg) applied along with grass plant fertilizer, and two Se forms (sodium selenate and sodium selenite), with six replications. The results of the present study suggest that, in tropical soil conditions, the application of Se as selenate at low doses is more appropriate for B. brizantha biofortification than Se as selenite, because it favors a greater shoot Se levels, better activation of the antioxidant system and reduces on lipid peroxidation. Finally, with an increase of Se rates, cellular modifications were observed in internal structures of roots in B. brizantha, with aerenchyma appearing.
