“…However, Hamilton and Thompson (1980) found negative effects of (Na + K)/Cl ratios below 1.91 or above 2.83 on feed efficiency, egg production and eggshell weight. In this study, the (Na + K)/Cl ratio that resulted in the best performance was 171.…”

-The objective of this study was to evaluate the potassium requirement for laying Japanese quails. Two hundred and forty quails were distributed in a randomized block design, with five treatments and six replicates, with eight birds each. The treatments consisted of a basal diet deficient in potassium (K) (2.50 g/kg), supplemented with potassium carbonate, to replace the inert, to reach levels of 2.50, 3.50, 4.50, 5.50 and 6.50 (g/kg) of K in the diet. There was a quadratic effect of K levels on feed intake, egg production, egg mass and feed conversion per egg mass and per egg dozen, estimating the requirements of 4.26, 4.41, 4.38, 4.43 and 4.48 (g/kg) of K diet, respectively. There was no significant effect on the levels of K in the diet on egg weight, albumen weight, percentage of yolk or shell and yolk color. However, yolk and shell weights reduced and the albumen percentage increased linearly with increasing levels of K in the diet. Despite the reduction of shell weight, the increased levels of K did not influence the specific gravity and shell thickness. The use of 4.41 g/kg of potassium is recommended in the diet for laying Japanese quails.

“…O fornecimento de uma ração contendo uma relação de (Na + +K + )/Cl -de 0,40 foi suficiente para se observar o aumento da mortalidade (HAMILTON & THOMPSON, 1980); entretanto, segundo os autores, o número de animais mortos foi insuficiente para garantir uma análise estatística rigorosa para este parâmetro. Segundo MONGIN (1981), quando o balanço ácido-base é desviado da homeostase para o estado de alcalose ou acidose, vias metabólicas podem ser alteradas, ficando mais envolvidas na regulação da homeostasia do que no crescimento ou produção do animal.…”

“…Essa necessidade de um maior período de observação para se verificar diferenças de caráter zootécnico pode ser um dos pontos que justificam a inconsistência de resultados positivos em estudos anteriores para o uso de balanço eletrolítico em dietas de poedeiras e matrizes (ERNEST et al, 1975;HAMILTON & THOMPSON, 1980;BALNAVE & MUHEEREZA, 1997). A diferença no número de pintinhos vendáveis por ave alojada (162 pintinhos para os galpões com o conceito de equilíbrio eletrolítico e 145 pintinhos para os galpões controle) é um número economicamente interessante para empresas que fazem desta venda de pintinhos sua atividade comercial.…”

Electrolyte balance in diets with reduced protein for semi-weighted laying hens in the second production cycle

et al. 2012

-The objective was to evaluate the effect of electrolyte balance in diets with reduced protein for semiweighted Bovans Goldline laying hens in the second production cycle. The design was completely randomized with five treatments and seven replicates of six birds per experimental unit. Treatment 1 consisted of a control diet containing 165.0 g/kg crude protein (CP), formulated with the addition of DL-methionine to meet birds requirements during the experimental period. To compose the treatments 2-5 (BE149, BE167, BE185 and BE203), a basal diet with reduced protein (135.0 g/kg CP) supplemented with synthetic amino acids DL-methionine, L-lysine, L-threonine, L-valine and L-tryptophan was formulated. This basal diet was supplemented with potassium carbonate, to replace the inert, so as to provide four levels of potassium (5.86, 6.56, 7.26 and 7.96 g/kg) corresponding to the electrolyte balance of 171, 149, 167, 185 and 203 meq/kg, respectively. There was increased linear effect for feed intake and decreasing linear effect for albumen weight and yolk percentage and quadratic effect for conversion per dozen and per egg mass. Crude protein is recommended at 135.0g/kg with 6.77 g/kg potassium and electrolyte balance of 172.51meq/kg in the diet of semi-weighted laying hens in the second production cycle.
