“…In fact, the significant mean square for diets (P<.01) can be attributed almost entirely to the difference between the weight changes of ratio .40 and those of the other ratios. There was no indication of any effect on body weight from dietary sodium levels, a result seemingly contradictory to that of Sauveur and Mongin (1978); however, their results were from growing birds while the present study involved only mature birds. Furthermore, the sodium, potassium, and chloride levels in the present diets were much higher than those used by Sauveur and Mongin (1978).…”

A 3 X 6 factorial experiment involving three strains of Single Comb White Leghorn hens and six dietary ratios of sodium plus potassium to chloride ((Na + K)/C1) of . 40, .91, 1.92, 2.83, 4.04, and 7.69 was done with 108 individually caged hens. The six corn-soybean meal-brewers' dried grains diets included comparisons among low and high levels of sodium and chloride. Feed and distilled water were provided ad libitum from 403 to 487 days of age. Egg and shell measurements were taken on eggs laid between 479 and 483 days. At the completion of the experiment, blood pH and gases (pC0 2 , p0 2 ) and plasma Na, K, Cl, Ca, P, and Mg were measured for each hen. Blood bicarbonate was calculated from the pH and pC0 2 values. Much of the variation in blood gas levels and 485-day body weight could be attributed to the effects of the .40 diet. The effects of dietary sodium and chloride levels appeared independent of each other with decreasing levels of sodium and increasing levels of chloride reducing blood pH, pC0 2 , and bicarbonate; these ions had the reverse effect on plasma K. Significant differences in feed intake, feed efficiency, and egg production were apparently due to extremely poor performance of birds fed the .40 diet. Differences among strains were significant for feed intake, productivity, egg and shell weight, percent shell, shell weight per unit surface area, and egg specific gravity but were not significant for blood gas and plasma inorganic ion levels, nondestructive deformation, compression fracture force, and interior quality. Increasing dietary chloride levels significantly reduced deformation and fracture force. There were few dietary (Na + K)/Cl ratio X strain interactions. Partial correlation coefficients indicated very weak relationships (r = -.19 to .14) between blood pH or bicarbonate and specific gravity, deformation, or fracture force. The results of this experiment indicate that although the acid-base balance of laying hens was influenced by the (Na + K)/Cl ratio of the diet, there was no relationship between acid-base balance and egg shell strength.

“…Novak et al (2004), no entanto, encontraram maior conteúdo de sólidos totais no albume em poedeiras arraçoadas com maior nível de lisina. Os resultados encontrados nesta pesquisa para sólidos totais dos componentes do ovo estão de acordo com os obtidos por Rizzo et al (2004) Apesar de os níveis de eletrólitos alterarem o equilíbrio hidroeletrolítico das mucosas intestinais (Sauveur & Mongin, 1978), o aumento do nível de cloro, pela incorporação de lisina-HCl, não foi suficiente para ocasionar má absorção do íon-cálcio ou influenciar a formação da casca.…”

RESUMO -Objetivou-se determinar os melhores níveis de lisina digestível para poedeiras em produção. Avaliaram-se o desempenho, o consumo de nutrientes, o metabolismo, a qualidade de ovos, os parâmetros sanguíneos e o desenvolvimento do aparelho reprodutor de 160 poedeiras Hy-Line W-36 com 25 semanas de idade. As aves foram distribuídas em delineamento inteiramente casualizado, com quatro níveis de lisina digestível (600, 700, 800 ou 900 mg de lisina/kg de ração) e quatro repetições, utilizando-se o esquema de parcelas subdivididas na avaliação do balanço de nitrogênio, dos parâmetros sanguíneos e do aparelho reprodutor. Os níveis de lisina da dieta influenciaram os consumos de alimento, proteína e energia, cujo ponto de máximo foi observado no nível de 720 mg de lisina. Para produção de ovos, o melhor nível foi 800 mg de lisina; para conversão alimentar, 900 mg; e, para balanço de nitrogênio, 700 mg. A digestibilidade de extrato etéreo, a qualidade dos ovos, o desenvolvimento do aparelho reprodutor e os parâmetros sanguíneos não foram influenciados pelos níveis de lisina digestível da dieta. Recomendam-se níveis de 700 a 800 mg de lisina digestível para metabolismo e desempenho e 600 mg para qualidade dos ovos e melhor desenvolvimento do aparelho reprodutor.Palavras-chave: aminoácido, oviduto, produção de ovos, qualidade de ovos, sangue Levels of digestible lysine for Hy-Line W-36 hens in production periodABSTRACT -In this experiment it was aimed to determine the best levels of digestible lysine for laying hens in production period. Performance, nutrients intake, metabolism, egg quality, blood parameters and development of reproductive tract for 160 Hy-Line W-36 hens at 25 weeks of age. Hens were distributed in a completely randomized design with four levels of digestible lysine (600, 700, 800 or 900 mg of Lys/kg) and four replicates by using a split spot scheme was used at evaluation of nitrogen balance, blood parameters and reproductive tract. Lysine levels in the diet affected food, protein and energy intakes whose maximum point was noted at the level of 720 mg of Lysine. For egg production, food conversion, and nitrogen balance, the best levels of lysine was 800 mg, 900 mg, and 700 mg, respectively. The digestibility of ethereal extract, egg quality, development of reproductive tract and blood parameters were not affected by levels of digestible lysine in the diet. It is suggested 700 and 800 mg of digestible lysine for metabolism and performance, respectively, and 600 mg for egg quality and better development of the reproductive trait.

“…There are reports in the literature (Israel et al, 1972;Sauveur and Mongin, 1978) indicating the importance of electrolyte balance (Na + K -CI) for hens, with the optimal level being 200 to 250 meq/kg of diet. However, most practical corn-soybean diets contain 140 to 180 meq/kg of diet.…”

“…However, most practical corn-soybean diets contain 140 to 180 meq/kg of diet. It has been reported that increasing the electrolytes to 200 by addition of Na2CC»3 and removal of salt will improve shell quality (Sauveur and Mongin, 1978). The improvement is due to the resultant increase in blood bicarbonate level.…”

Evidence for Absorption of Silicon and Aluminum by Hens Fed Sodium Zeolite A

et al. 1993

The mechanism of action of zeolite A (ZA) on eggshell quality could be related either to its ion-exchange properties or to individual ZA elements (Al or Si). Two experiments were conducted to determine 1) whether any ZA passes through the digestive system in its original form; and 2) whether any Al and Si absorption occurs. In Experiment 1, unfed hens were intubated with either 0 or 5 g ZA at oviposition. In Experiment 2, fed and unfed hens were intubated at oviposition with 0, 1, or 2 g ZA. At the subsequent oviposition, liver and kidney tissues, excreta, urine, bile, and plasma were collected and analyzed for Al, Si, Na, K, and P. The results indicated that approximately 7% of the intubated ZA passed through the digestive system in its original form (Experiment 1). As the intubated level of ZA increased, excreta Al and Si (P < .0001), urine Si (P < .005), and urine Al (P < .07) also increased (Experiment 2). Aluminum recovery from excreta ranged from 75 to 93% of the quantity intubated in all treatments. Corresponding values of Si from excreta of unfed and fed hens ranged from 76 to 81% and 58 to 60%, respectively. The P content of excreta was not influenced by ZA. However, excreta P was greater (P < .0001) in unfed than in fed hens. Neither plasma electrolytes (Na, K, and P) nor Al or Si levels in either liver or kidney were influenced by ZA.(ABSTRACT TRUNCATED AT 250 WORDS)
