“…Those hormones regulate Ca flow between these organs and the extracellular fluid, resulting in less than 5% variation in Ca blood levels under normal circumstances, and only occurs when hormonal mechanisms fail, secondarily to reduced intestinal absorption (Macari et al, 2002). In the present study, mean Ca serum values were lower than those obtained by Vieites et al (2011), of 6.72 and 6.89mg/dL.…”

Antagonism, digestible amino acid, egg components, Haugh units. ABSTRACTThe dietary inclusion of phytase increases nutrient and energy bioavailability for broilers. The effect of phytase increases nutrients and energy bioavailability for either the objective of this experiment was to evaluate the influence of nutrient and energy reduction in diets supplemented with phytase on the performance, gastrointestinal pH, organ and bone composition, and blood biochemistry of broilers between eight and 21 days of age. In the study, 1.120 male Cobb 500® broilers, with 161±1g average weight, were used. At eight days of age, birds were distributed according to a completely randomized experimental design with seven treatments in a 3x2+1 factorial arrangement with eight replicates of 20 broiler each. Treatments corresponded to reduction of calcium (Ca) and phosphorus (P), amino acids and energy, or reduction of Ca, P, amino acids and energy; supplementation or not of phytase; and a positive control treatment. Broiler fed the diet with reduced Ca and P levels and phytase supplementation presented the best performance of all groups. The diet with reduced amino acid and energy levels and phytase addition reduced gizzard and proventriculus pH. Dietary Ca and P reduction increased relative liver and heart weights, as well as albumin blood levels. The bones of broilers fed phytase-supplemented diets presented higher ash content.

“…The P variable presented a linear effect (p <0.05) for the DEB levels tested, different from what was observed by Vieites et al [32], who found no variation for the levels of 0 to 350 mEq of DEB/kg on phosphorus. Junqueira et al [33] found changes in P levels in diets with different DEB and reported that dietary sodium, when absorbed, combines with phosphorus plasma, forming sodium phosphate, and therefore facilitates its elimination by the kidneys, it has beneficial effects on the incorporation of calcium into the carbonate ion, with the consequent increase in calcium carbonate synthesis, what may justify the decrease in the serum phosphorus level as the DEB level increases in this experiment.…”

The aim of this study was to evaluate the effect of different dietary electrolyte balance (DEB) levels over the hematological parameters and the biochemical profile of broilers under stress caused by cyclic heat. We used 1050 male broilers from Ross lineage, for two experimental phases: phase 1 (broilers from 1 until 21 days old) and phase 2 (broilers from 22 until 42 days old). The broilers were distributed under a completely randomized design, built for five treatments (110; 175; 240; 305; 370 mEq of DEB/kg of ration) and seven repetitions. For the hematological analyses were used two broilers in each repetition, one to blood count evaluation (Hemogram) and another one to the biochemistry evaluation, collected in the end of each experimental phase. During the phase of 1 - 21 days old, the variable hemoglobin number (Heme), mean corpuscular volume (MCV) and Serum Chloride (Cl) presented a linear effect (p<0,05) DEB levels. There was no effects (p>0,05) over the corpuscular volume (CV), total plasma protein (TPP), leukocytes number (Leu), heterophiles (Het), lymphocytes (Lyn), eosinophils (Eos), basophils (Bas), monocytes (Mon), calcium (Ca), phosphor (P), uric acid (UA) e urea (U). During the phase two of 22 – 42 days old there was effect (p<0,05) quadratic to the variables Leu and Het and linear to the variable P and significative difference (p<0,05) between the variable means UA at the levels of DEB tested.There was no effect (p>0,05) over the variable CV, Heme, MCV, TPP, Lyn, Eos, Bas, Mon, Cl, Ca and U on the DEB levels tested. The supplementation of the DEB levels 110, 175 e 240, 305 and 370 to the phase from 1 until 21 days old presented great results in the hematological evaluation and biochemical, because it provided possibly a longer useful life to the Hem without promoting a metabolic imbalance. In the phase from 22 until 42 days old the level of 268 to 280 mEq of DEB/kg of ration presented a better answer from the broilers immune systemic.

“…Matos et al (2009), ao trabalharem com dois níveis (15,03 e 18,03%) de PB e correção do BE para 250 não encontraram diferenças entre as médias dos tratamentos com PB de 15,03 e 18,03% para as concentrações plasmáticas de sódio, potássio e cloro de frangos de corte aos 42 dias de idade. Em estudo mais recente, Vieites et al (2011b) trabalharam com 8 níveis de BE variando de 0 a 350 e dois níveis (20 e 23%) de PB e também não observaram efeito dos níveis de PB sobre os valores plasmáticos de cálcio e proteína total, contudo os autores observaram elevação de 6,52 para 6,78 mg/dL quando foi reduzido o teor de PB de 23 para 20%. Com relação aos níveis de BE os autores encontraram efeito quadrático (P<0,05) sobre os valores de proteína total do sangue das aves, para os dois níveis de PB estudados, e queda linear (P<0,05) nos níveis plasmáticos de cálcio das aves recebendo dietas com 23% de PB.…”

The aim of this study was to evaluate the effect of different levels of crude protein (CP) and electrolyte balance (EB) of the feed of broilers. 480 male broiler of Cobb 500 strain were fed in the period 36 to 42 days of age with two basal diets, one with EB 200 and another with 240 mEq. kg -1 , combined with CP levels of 18.00, 17.28, 16.56 and 15.84%. The reduction in CP levels had growing linear effect (P <0.01) on feed conversion of birds (BE 200 and 240) even with the supplementation of industrial amino acids. For weight gain, reduced levels of CP had decreasing linear effect (P <0.01) to birds consuming diets with EB of 240 mEq. kg -1 and quadratic effect (P <0.05) for those who consumed ration with EB than 200 mEq. kg -1 being the level of 17.54%, which resulted in better weight gain of birds. There was linear effect (P <0.05) of reduction in CP levels on the plasmatic values of sodium (EB200) and chlorine (EB240) and quadratic effect (P <0.05) on plasmatic concentration of potassium (EB200) of birds, being the level of 17.05%, which provided the lower potassium values. For the plasma levels of uric acid, total protein and calcium, and bone development, reduction in the levels of CP had no effect on neither one of EB levels studied. Supplementation with bicarbonate salts of sodium and potassium chloride was not effective in improving the performance characteristics the birds, in the values of electrolyte balance studied, since there were no performance improvements with increase the electrolytic balance of the diets of 200 to 240 mEq.kg -1 .
