“…According to Melo and Moura (2009), higher solubility of Ca sources improves bioavailability and intestinal absorption of Ca. They also emphasize that organic sources of this mineral (such as seaweed, shells, bones and eggshell) present higher solubility compared to inorganic sources (MELO;MOURA, 2009). Despite this, inorganic sources are the most commonly used in animal feed because they are abundant and inexpensive, such as limestone and dicalcium phosphate.…”

This study aimed to evaluate the use of wattle tannin as an adsorbent of toxic metals in broilers fed on diets with different levels of replacement of limestone with golden mussel meal. First, we conducted a trial to evaluate the performance of broiler chicks from 1 to 21 days old when fed on wattle tannin. For this we used 720 male broiler chicks that were one day old, in a completely randomized design with six treatments and six replications. The treatments were composed of basal diets with increasing levels of wattle tannin (0, 250, 500, 750, 1000 and 1250 g tonne-1), where the tannin replaced the inert material of the feed. All of the diets were isonutritive and isocaloric. The results showed that 250 g tonne-1 of tannin was detrimental to weight gain, final weight and feed conversion, and the use of 1000 g tonne-1 of wattle tannin, in addition to these effects, caused a drop in consumption of the ration. There was no effect of treatment on morphometric measurements of villi, crypt or the villus:crypt ratio. Next, we conducted a second test to evaluate the performance of broiler chicks from 1 to 21 days of age when fed with increasing levels of replacement (0, 25, 50, 75, 100%) of limestone with golden mussel and even supplementation or not wattle tannin. Five repetitions were used and the birds were housed in a completely randomized design. In diets with the inclusion of tannin, 250 g tonne-1 of wattle tannin was used, which replaced the inert material in the feed. In this test, 1200 male broiler chicks that were one day old were used. The results showed that the golden mussel contains large quantities of calcium, with low concentrations of toxic metals and microbiological contamination within the allowed range. Performance data show that mussel can be used to replace up to 100% of limestone in feed without affecting the variables, but the use of 250 g tonne-1 of wattle tannin affects the performance of chicks. Bone quality was not changed by the treatments. Phosphorus and calcium in the bones remained stable during treatment and only the gray variation showed interaction effects from the use of mussel and wattle tannin.

“…Neither were significant differences observed in the chemical composition of the flesh of animals that received the combination of additives (P>0.05). When using calcareous seaweed flour in beef cattle from extensive breeding schemes, Melo & Moura (2009) did not evaluate their effects on the meat's chemical composition. For the reason that this compound is rich in highly available minerals, changes related to the meat's mineral matter could occur.…”

“…For the reason that Lithothamnium calcareum is basically composed of minerals, such as copper, some of these elements may have led to changes. Dias (2000) found primarily calcium carbonate and magnesium, besides over 20 trace elements such as Fe, Mn, B, Ni, Cu, Zn, Mo, Se and Sr, which show great bioavailability for intestinal absorption (MELO & MOURA, 2009). The calcareous seaweed flour treatment led to a 74% increase in the content of linolenic acid (C 18:3) as compared to control.…”

Food additives were used to improve meat characteristics of Brangus heifers supplemented on pasture daily (0.32% LW). The treatments were: supplement (with no additives); calcareous seaweed flour (Lithothamnium calcareum) added to the supplement; vitamin E and organic selenium added to the supplement; protected fat added to the supplement; a subcutaneous application of vitamin D seven days before slaughter + supplement; and the association of vitamin E, organic selenium and protected fat added to the supplement + one subcutaneous dose of vitamin D seven days before slaughter. The animals were supplemented by 109.80±11,71 days and were slaughtered when they reached approximately 337.95±20,56kg of LW. The experimental design was completely randomized with six treatments and 25 repetitions. TheLongissimus dorsi muscle’s chemical composition did not differ between treatments (P>0.05). The use of seaweed flour, vitamin D, protected fat and the association of additives has the potential to improve the concentration of some unsaturated fatty acids in the Brangus heifers’ meat (P˂0.05), but without improving the level of unsaturated fatty acids class. We conclude that the use of additives in heifers finished in the pasture/supplement system has no effect on the meat quality, but only, isolated outcomes, on the content of some fatty acids.

“…Inúmeros compostos são tidos como potencias fontes de cálcio, sejam eles orgânicos (farinha de ossos, conchas, e algas) ou inorgânicos (rochas) (MELO & MOURA, 2009). No entanto, sem análise prévia para utilização na nutrição de aves poedeiras encontram-se incertezas quanto a sua eficácia para este fim.…”

IntroduçãoA avicultura tem se destacado no mercado mundial, grande parte desse crescimento deve-se a produção de ovos. Tal sucesso é possível pelas inúmeras contribuições de pesquisas cientificas aliadas ao incentivo financeiro no ramo, que torna o setor mais rentável e atrativo para produtores. Com esses avanços foi possível produzir, somente no Brasil, cerca de 39,1 bilhões de ovos no ano de 2016 (ABPA, 2017).Buscando sempre o aumento da quantidade e da qualidade na produção avícola, várias organizações realizam pesquisas visando, principalmente, o aumento produtivo ou redução do custo de produção. Fatores estes que podem ser influenciados pela utilização de diferentes componentes na alimentação, tendo em vista que a alimentação é responsável por cerca de 60% dos custos na produção de ovos (GIROTTO, 2008). Entretanto, a modificação nos constituintes da ração para melhor adequação da mesma à realidade do produtor, não pode influenciar negativamente na qualidade do produto final.
