Performance and egg quality of Japanese quail fed diets containing microalgae S...
Santana,Lidiane da Costa; Mendonça,Michele de Oliveira; Silva,Vanessa Riani Olmi; Castro,Mailson das Dores Adriano; Costa,Patrícia Kelly FelixABSTRACT A trial was carried out to evaluate the effects of different levels of microalgae Schizochytrium sp. on performance, yolk lipid profile, and egg quality of Japanese quail. A flock of 210 quail was distributed in a completely randomized design, with five treatments (0, 10, 20, 30, and 40 g of Schizochytrium sp./kg of feed) and six replications with seven birds per cage. Performance and egg quality were ...
Fiber source and xylanase on performance, egg quality, and gastrointestinal tra...
Sousa,Lorena Salim de; Carvalho,Thiago Soares Martins; Nogueira,Flávia Aparecida; Saldanha,Mariana Masseo; Vaz,Diego PereiraABSTRACT The objective of this study was to ascertain the influence of different dietary fiber sources and the usage of xylanase on diet of commercial layers and their influence on productive performance, egg quality, and digestive organ biometry. A total of 864 Lohmann® White hens was fed diets with three different fiber sources (wheat bran, soybean hull, or coffee husk) with or without xylanase inclusion (con...
Dietary levels and sources of selenium for post weaning piglets
Oliveira,Tiago Ferreira Birro; Bertechini,Antônio Gilberto; Philomeno,Renato; Silva,Vanessa AvelarABSTRACT: An experiment was conducted to study the effects of two sources and dietary levels of selenium (Se) on performance, Se concentration and glutathione peroxidase activity in plasma and liver of piglets post weaning. A total of 126 weaned pigs male and female Large White × Landrace, at average body weight of 7.2±0.67kg were allotted to seven treatments in a randomized block design, with two Se sources (o...
Increasing levels of phytase in diets formulated with reduced available phospho...
Naves,Luciana de Paula; Rodrigues,Paulo Borges; Teixeira,Levy do Vale; Bertechini,Antônio Gilberto; Alvarenga,Renata RibeiroThe reduction of the available phosphorus (avP) content in the broiler diet must be followed by the supplementation of adequate phytase. One experiment was conducted with broilers from 15 to 28 days of age to determine the level of necessary phytase when the mashed diet is formulated with 0.213% of avP to enable the results of performance, tibia ash content, and calcium (Ca) utilization similar to those determi...
Redução de fósforo em dietas para frangos com base em valores de equivalência d...
Naves,Luciana de Paula; Rodrigues,Paulo Borges; Bertechini,Antônio Gilberto; Lima,Eduardo Machado Costa; Teixeira,Levy do Vale; Alvarenga,Renata RibeiroO objetivo deste trabalho foi avaliar o uso de valores de equivalência da fitase como base para redução de fósforo disponível (P-disp) em dietas para frangos. Foram avaliados dez planos nutricionais com seis repetições de 15 aves cada uma. Avaliaram-se: desempenho, teor de cinzas na tíbia e custo da ração. De 1 a 7 e de 36 a 42 dias de idade, as aves receberam dieta basal; de 8 a 21 dias, dieta sem fitase conte...
Activity of fungal phytases stored in two ways in response to the period of sto...
Naves,Luciana de Paula; Corrêa,Angelita Duarte; Bertechini,Antônio Gilberto; Gomide,Elisangela Minati; Abreu,Celeste Maria Patto deTwo distinct experiments were conducted simultaneously with phytases of Aspergillus oryzae and A. niger for determining enzyme activity in response to storage period (up to 180 days at room temperature - RT). In the first experiment, enzymes were stored as they were acquired (pure form) and the activity was measured periodically during 180 days of storage at RT. In the second experiment, the phytases were incor...
Effects of dietary mineral bioplex in pregnant and lactating sow diets on pigle...
Bertechini,Antônio Gilberto; Fassani,Edison José; Brito,Jerônimo Ávito Gonçalves de; Barrios,Priscilla RocheleA total of thirty-six Landrace × Large White sows were inseminated with semen of Large White boars and studied in late pregnancy (30 days pre-partum) and lactation phases to determine the effects of trace mineral supplementation in organic (bioplex) and inorganic forms at two levels of supplementation (1 and 2 kg/t) on the reproductive performance of the females and on piglet performance and physiologic charact...
Energetic and nutrient metabolizability values of corn obtained with nutritiona...
Makiyama,Letícia; Alvarenga,Renata Ribeiro; Rodrigues,Paulo Borges; Zangeronimo,Márcio Gilberto; Oliveira,Evelyn Cristina deThe experiment was carried out to evaluate the influence of nutritional correction on the partial diet replacement or pure-food methodology to determine the energy values (apparent metabolizable energy - AME and nitrogen-correct apparent metabolizable energy - AMEn) and coefficient of metabolizability of nutrients of maize. The method of total excreta collection was used, with 120 female Cobb 500® broilers weig...
Nitrogen, calcium and phosphorus balance of broilers fed diets with phytase and...
Gomide,Elisangela Minati; Rodrigues,Paulo Borges; Zangeronimo,Márcio Gilberto; Bertechini,Antônio Gilberto; Santos,Luziane Moreira dosThe objective of this study was to evaluate the effect of reduced-crude protein (CP) and available phosphorus (aP) diets, added with phytase and amino acids for broilers in the growing (14 to 21 days old) and retirement (35 to 42 days) phases on nitrogen, potassium and phosphorus balance. Ninety Cobb broilers were distributed in a completely randomized design with three treatments and six replications with five...
Rações com níveis reduzidos de proteína bruta, cálcio e fósforo com fitase e am...
Gomide,Elisangela Minati; Rodrigues,Paulo Borges; Bertechini,Antônio Gilberto; Freitas,Rilke Tadeu Fonseca de; Fassani,Édson José; Reis,Matheus de PaulaEm experimentos de desempenho e metabolismo, avaliaram-se os efeitos do fornecimento de rações com níveis reduzidos de proteína bruta, cálcio e fósforo disponível sobre o desempenho, as características de carcaça, o conteúdo de cinzas na tíbia, o balanço e a retenção de nitrogênio e fósforo de frangos de corte nos períodos de 8 a 21 e 8 a 35 dias de idade. Em cada uma destas fases no ensaio de desempenho, foram...
