Sunflower Meals in Pullet Developer Diets

Abstract

Two experiments were conducted with egg strain replacement pullets from the ages of 12 weeks (Experiment 1) or 8 weeks (Experiment 2) to 20 weeks of age to evaluate the replacement value of sunflower meal for soybean meal. Sunflower meal with or without lysine, and with lysine and methionine completely replaced soybean meal.In Experiment 1, two sunflower meals (28 and 34% protein) were used. The addition of lysine to either of the two sunflower meals failed to improve growth or feed efficiency. When birds were housed in cages, the diets utilizing 28% protein meal produced pullets smaller and less efficient than did the other diets. This effect was not observed when the floor management system was used.In Experiment 2, only one sunflower meal (34% protein) was used. The additions of methionine, or lysine, or both to sunflower meal did not improve the weight gains. However, from 8 to 12 weeks, the addition of lysine alone and the combination of lysine and methionine to the sunflower diet did improve feed efficiency. For the period 12 to 20 weeks, the combination improved feed efficiency for the caged birds. In 11 of 14 weight comparisons die complete substitution of sunflower meal for soybean meal did not significantly reduce weight gain. Due to the weight gain and the feed efficiency data, the feed costs per pullet for either 12 to 20 weeks or 8 to 20 weeks were generally lower for die sunflower meal. The result was less cost because sunflower meal was about 30% cheaper than soybean meal. (

Desempenho, características de carcaça e constituintes corporais de ovinos Santa Inês alimentados com farelo de girassol em substituição ao farelo de soja na dieta

“…O farelo de girassol é um subproduto da indústria de óleos vegetais, resultante da moagem de sementes de girassol no processo industrial de extração do óleo, podendo ou não conter casca e apre-sentando grande variação na sua composição em proteína bruta, que oscila entre 28 e 44% (Michael & Sunde, 1985). A porcentagem de fibra bruta pode variar de 14 a 20,6% (Green & Kiener, 1989) de acordo com a quantidade de casca presente no farelo.…”

“…A grande variação na quantidade de fibra bruta pode levar a diferenças nos valores energéticos. Michael & Sunde (1985) determinaram para o farelo de girassol valores de 1.907 kcal EM/kg. Garcia et al (2005), em experimento com bovinos holandeses em fase de crescimento, forneceram níveis de 0, 15, 30 e 45% de farelo de girassol nos concentrados e não observaram diferenças significativas para o consumo (em kg/dia e por peso metabólico) de MS, PB, EE, extrato não nitrogenado e cinzas.…”

The Practical Application of Sunflower Meal in Poultry Nutrition

“…In most of these studies, SFM was able to replace 50-100% of the SBM protein without adversely affecting the productive performance of laying hens (Rose et al, 1972;Deaton et al, 1979;Zhu et al, 1983;Michel and Sunde, 1985;Kashani and Carlson, 1988;Aguillera et al, 1989;Francesh et al, 1995). McNaughton and Deaton (1981) pointed out that SFM could be included in layer dies up to 30%, subsequently replacing 100% of the SBM without drastic effect on live body weight, egg weight or egg production.…”

Metabolizable energy and standardized ileal digestible amino acid contents of a high-protein sunflower meal fed to broiler chicks

“…Compared with SBM, the high dietary fiber content, low Lys content, and presence of chlorogenic acid in SFM are the main challenges of using it in poultry diets (Milić et al 1968;Musharaf 1991;NRC 1994;Senkoylu and Dale 1999). However, these challenges can be overcome by dehulling of sunflower seeds to reduce fiber content (Abbas and Yagoub 2008), and supplementing SFM-based diets with Lys to meet the requirements and with choline and Met to alleviate the antinutritive effects of chlorogenic acid (Michel and Sunde 1985;Rad and Keshavarz 1976;Senkoylu and Dale 1999).…”
