ABSTRACT

This study evaluated the performance and the quality and fatty acid profile of eggs from laying hens fed diets containing mixed crude glycerin (MCG; 80% vegetable fat + 20% animal fat). A total of 240 39-week-old Hy-Line W36 laying hens were distributed according to a completely randomized experimental design into six treatments consisting of graded MCG dietary inclusion levels (0, 1.5, 3.0, 4.5, 6.0, and 7.5%), with five replicates of eight birds each. Feed intake linearly decreased (p 0.05) with increasing MCG inclusion levels. The percentages of myristic, palmitic, and -linolenic acids in the eggs linearly decreased as MCG dietary levels increased (p 0.05), while -linoleic acid, polyunsaturated fatty acids (PUFA) and -6/-3 ratio linearly increased. Excreta moisture linearly increased with increasing levels of MCG inclusion (p 0.05). MCG may be included in up to 7.5% in layer feeds without impairing performance or egg quality, but levels up to 5.54% reduce SFA egg content. However, the inclusion of MCG in layer diets increases -6/-3 ratio in the eggs.(AU)

ABSTRACT

O estudo foi conduzido para testar a ação do formiato de sódio sobre o desempenho de frangos de corte. No primeiro experimento, foi avaliado o formiato de sódio em níveis crescentes na dieta e, no segundo, a substituição do cloreto de sódio pelo formiato de sódio, com adição de cloreto de amônia para ajuste do balanço eletrolítico. Aos 7, 14 e 21 dias de idade, foram avaliados o consumo de ração, ganho de peso e conversão alimentar e, aos 7 e aos 21 dias, medidos o consumo de água e a umidade das excretas das aves. Os dados obtidos foram submetidos à análise de variância e comparados pelo teste de Tukey. O desempenho de frangos de corte não é afetado quando o formiato de sódio é utilizado em substituição parcial ou total do cloreto de sódio na dieta. Porém, com a adição do formiato de sódio, deve-se observar o nível de sódio e cloro da dieta, de acordo com as exigências das aves.


This study was developed to evaluate the action of sodium formiate on broiler performance. In the first experiment it was tested the sodium formiate increasing levels in diet, and in the second experiment, it was valuated the replacement of sodium chloride by sodium formiate, with the addition of ammonium chloride for adjustment of electrolyte balance. At 7, 14 and 21 days, feed intake, weight gain and feed conversion were evaluated, and at 7 and 21 days, water intake and excreta moisture were evaluated. The data were submitted to analysis of variance and compared by Tukey test. The performance of broilers is not affected when sodium formate is used in partial or total replacement of sodium chloride in the diet. But with the addition of sodium formate, it should be noted the level of sodium and chlorine in the diet, according to birds' requirement.

ABSTRACT

Com o objetivo de determinar os melhores níveis nutricionais de cloro para codornas italianas destinadas à produção de carne (um a 49 dias de idade), foram utilizadas 384 codornas com um dia de idade, distribuídas em delineamento inteiramente casualizado, com seis tratamentos e oito repetições de oito aves por unidade experimental. Os níveis de cloro avaliados foram: 0,07; 0,12; 0,17; 0,22; 0,27 e 0,32%. Não foram observados efeitos significativos dos níveis de cloro das rações sobre todos os parâmetros avaliados. Considerando-se que os níveis de cloro não promoveram sinais de deficiência ou excesso que pudessem ser determinados por alterações no desempenho das codornas, pode-se recomendar que rações para codornas de corte de um a 49 dias de idade podem conter níveis de 0,07 a 0,32% de cloro .(AU)


In order to determine the best nutritional levels of chlorine in Italian quails destined for meat production (aged 1 to 49 days), 384 one-day-old quails were distributed in a completely randomized design with six treatments and eight replications of eight birds per experimental unit. The chlorine levels evaluated were: 0.07, 0.12, 0.17, 0.22, 0.27 and 0.32%. There were no significant effects of the diet chlorine levels on any of the parameters evaluated. Considering that the chlorine levels did not cause any signs of deficit or excess that could be determined by changes in the performance of quails, we can recommend that diets for meat quails aged from 1 to 49 days may contain chlorine levels from 0.07 to 0.32% .(AU)
