Feeding value of de-hulled sunflower seed meal for broilers

Abstract

The effects of de-hulled sunflower seed meal (SFM) samples with different crude protein (CP) and non-starch polysaccharide (NSP) content on apparent metabolizable energy (AME), AME metabolizability (EM) and pre-caecal protein digestibility (pcPD) were examined. The birds were fed one of four mash diets. On a per kilogram basis, the basal diet (BD) contained as major ingredients 549.5 g wheat, 150 g soybean meal and 175 g full fat soybean meal as well as 215.4 g crude protein kg -1 and 12.81 MJ AME kg -1 . Another three diets containing 200 g kg -1 of each of three experimental SFM samples in place of the BD were also mixed. Each diet was fed to birds in ten pens with two male Ross 308 broilers ranging in age from 8 to 21 days. Dietary AME was determined from excreta collection between days 17 and 21, while AME, EM and pcPD were determined when the birds were 21 days old. The substitutional method was used to determine AME, EM and pcPD in the SFM samples. The SFM samples high in NSP had lower AME (P = 0.001), EM (P < 0.001) and pcPD (P = 0.005). The beneficial effect of carrying out a further de-hulling of SFM seems to be mediated through reduced NSP content and improved energy and protein bioavailability.

Nutritive value of full-fat dehulled sunflower seeds in diets for broiler chickens

“…These results may be because of the increase in CF content from sunflower meal in the diet. Karkelanov et al (2020) found an increase in AME when the SFM (20% of the diet) had low fibre content. Therefore, the de-hulling process is important to reduce the fibre content of DHSS (Senkoylu & Dale, 2006;Viveros et al, 2009).…”

“…The fibre content, digestibility, and bioavailability of nutrients in SFM can vary, depending on whether the hulls are included (Laudadio et al, 2014;Karkelanov et al, 2020) and growth performance can alter because of these differences (Khempaka et al, 2009). The main objective of the present study was to evaluate the composition and metabolizable energy of DHSS, and the effects of the partial replacement of SBM with DHSS on the digestibility of nutrients, relative weight of digestive system organs, colour of the breast meat, and performance in finisher broiler chickens.…”

Sunflower Meal Inclusion Rate and the Effect of Exogenous Enzymes on Growth Performance of Broiler Chickens

“…It is of broad availability globally, due to its wide adaptability to a range of soil and climatic conditions, it is rich in crude protein content, methionine, and have limited antinutritional factors [7][8][9]. However, its use in broiler feed has been limited by low levels of lysine and high crude fibre, high non-starch polysaccharides concentrations, low metabolizable energy content and some presence of chlorogenic acid [10][11][12][13].…”

Effect of adding sunflower seeds in broiler diet on serum lipids profile and some productive performance

“…SFM is a better choice than SBM because it has more crude protein (280 -420 g/kg), more methionine, and no anti-nutrients (Yusuf et al, 2012). In SFM, the hulls can alter the fiber content, digestibility, and bioavailability of nutrients, and growth performance can be affected as a result (Karkelanov et al, 2020). However, the solubility and concentration levels of fiber in poultry diets can have a significant impact on performance (Tufarelli et al, 2018).…”
