“…Heat-stressed birds develop metabolic acidosis, which first stimulates mineral dissolution and then the cell-mediated bone resorption due to the increased calcium excretion by the kidneys (Riond, 2001;Oliveira et al, 2010). This calcium loss results in reduced bone mineralization and may affect mechanical quality of the bones.…”

Ash, mineral density, femoral bone strength, tibia, vitamin C. ABSTRACTThis experiment was conducted to evaluate the effect of in-ovo ascorbic acid (AA) injection on the bone development of broilers submitted to heat stress during incubation and rearing. One thousand (1,000) Cobb ® fertile broiler eggs were randomly distributed according to the weight into five incubators, with 200 eggs per incubator. The incubation treatments were: eggs not injected with AA and incubated at 37.5°C; eggs not injected with AA and incubated at 39°C; and eggs injected with 6 µg AA/100 µL water prior to incubation and incubated at 39ºC. The hatched birds were reared at three different house temperatures: cold, thermoneutral, or and hot. The high incubation temperature negatively influenced broilers' bone characteristics. The femur of the birds hatched from eggs incubated at 39°C and injected with AA presented lower shaft mineral density, lower maximum force and lower elongation at maximum force. Their tibia presented reduced mineral density at the proximal and distal epiphysis. In-ovo AA injection of eggs incubated at high temperature did not minimize the negative effects of high rearing temperature on the performance andbone development of broiler chickens reared until 42 days of age.

“…Na literatura (VIEITES et al, 2004;ARANTES;STRINGHINI, 2010;ARAÚJO et al, 2011) tem sido relatado que dietas ácidas ou de baixo balanço eletrolítico, induzem a liberação de cátions do osso para o sangue para corrigir o pH, sendo o cálcio o principal cátion liberado. Assim, a reabsorção óssea resulta em sua menor mineralização e, consequentemente, em menor peso, densidade e resistência.…”

“…Esse mineral está envolvido na regulação da pressão osmótica, no equilíbrio ácido-base, na transmissão de impulsos nervosos, no processo de absorção de nutrientes como carboidratos, aminoácidos, minerais e vitaminas e no consumo de água, tornando-o indispensável para o crescimento das aves (VIEITES et al, 2004;ARAÚJO et al, 2011;PINHEIRO et al, 2011).…”

ResumoAvaliou-se o efeito do nível de sódio da ração sobre os parâmetros sanguíneos e no desenvolvimento ósseo de codornas destinadas a produção de carne. Foram utilizadas 384 codornas italianas, distribuídas em um delineamento inteiramente casualizado, com seis tratamentos e oito repetições de oito aves por unidade experimental. Os tratamentos consistiram de rações isonutrientes, exceto para o nível de sódio, que foram: 0,07; 0,12; 0,17; 0,22; 0,27 e 0,32%. As aves foram alimentadas de 1 a 49 dias de idade com as rações experimentais. Aos 49 dias, foram selecionadas duas aves por parcela para a coleta do sangue e retirada das tíbias. Foram avaliados o pH e a concentração de Na, Cl e K no sangue e o comprimento, diâmetro, peso, índice de Seedor, teor de matéria seca e cinzas, deformidade e resistência à quebra da tíbia. Os níveis de sódio da ração não influenciaram significativamente o pH, as concentrações de Na, Cl, K no sangue, comprimento, diâmetro, teor de matéria seca e cinzas e deformidade da tíbia. Entretanto, houve efeito quadrático sobre o peso, índice de Seedor e resistência à quebra, com ponto de máximo estimado em 0,19% de Na para todos os parâmetros. Conforme os resultados, a melhor qualidade óssea para codornas de corte foi obtida com 0,19% de sódio na ração. Palavras-chave: Balanço eletrolítico, desenvolvimento ósseo, índice de Seedor AbstractWe evaluated the effect of the level of sodium in the diet on blood parameters and bone development of quails for meat production. 384 Italian quails were used and distributed in a completely randomized design with six treatments and eight replicates of eight birds each. The treatments consisted of diets isonutrientes, except for the level of sodium, which were 0.07, 0.12, 0.17, 0.22, 0.27 and 0.32%. Birds were fed from 1 to 49 days old with the experimental diets and at 49 days, two birds were selected per replicate for blood collection and removal of the tibia. Were evaluated the pH and the concentration of Na, Cl and K in the blood and the length, diameter, weight, Seedor index, dry matter content and ash content, deformity and resistance to breakage of the tibia. The sodium content of the diet did not significantly affect the pH, concentrations of Na, Cl, K in the blood, length, diameter, dry matter and ash and deformity of the tibia. However, there was a quadratic effect on weight, Seedor index and resistance to breakage, with point of maximum estimated at 0.19% Na in diet, for all parameters. As the results, the best quality bone for quails was obtained with 0.19% sodium diet.

“…The IH2O was reduced with the substitution of soybean meal by babassu pie according to the equation: CH 2 O (mL) = 2092 to 5.995 NS (r² = 0.71; P<0.0018). According to Borges et al (2003) and Oliveira et al (2010), the electrolyte balance of the feed is directly related to water intake, so larger relations Na + + K + -Cl -cause increased intake. Whereas the soybean meal used in the formulation of the experimental diets contained 1.83% potassium while the babassu pie contained 0.48% (Table 1), increasing levels of substitution of soybean meal with babassu pie promoted a reduction in graded concentrations of potassium and thereby reduced the electrolyte balance of the feed 212.3 177.0 mEq/ kg (Table 2), which may explain the reduction of IH2O by broilers.…”

Replacement of soybean meal by babassu pie in balanced rations for broilers from one to 21 days of age

et al. 2015

The objective of the present study was to evaluate the effect of substitution level of soybean meal by babassu pie on the performance and cost feed rations to broilers of one to 21 days of age. Two hundred male broiler chicks at one day of age were used, distributed in a completely randomized design with four treatments (0, 10, 20 and 30 % substitution of soybean meal by babassu pie) with five repetitions of 10 broilers each. The performance (weight gain, feed intake, feed conversion and water intake), organ biometrics, feed cost per kg and per kilogram body weight were evaluated. The substitution of soybean meal by babassu pie was significantly in (P<0.05) negatively weight gain, feed conversion, water intake and body weight at 21 days of age, with no effect (P>0.05) on feed intake. The levels of substitution of soybean meal by babassu pie did not affect (P>0.05) the relative weights of the heart or liver, or the relative weight or length of the small intestine; however, it did affect (P<0.05) the relative weight of the gizzard. The lowest cost per kg was obtained from weight gain satisfaction with the diet of 0% babassu pie, which resulted in a higher gross margin for food. The replacement of soybean meal by babassu pie impaired the performance of broilers from one to 21 days of age, being technically and economically unfeasible.
