“…These results are consistent with those reported in literature (Tsuzuki et al, 2003;Secoylu et al, 2004;Rezaei & Hafezian, 2007). Only Casartelli et al (2006) showed an improvement in eggshell parameter as a function of increasing sunflower meal inclusion levels in the diet of commercial layers.…”

“…However, the sunflower meal utilized in the diets were submitted only to partial oil extraction, and therefore nutritional value was much higher than that of the SFM utilized in the present study. Most of the results reported in the literature recommend the utilization of SFM levels close to those included here (Tsuzuki et al, 2003;Casartelli et al, 2006;Rezaei & Hafezian 2007;Junqueira et al, 2010). Feed intake, egg mass, egg weight, and feed conversion ratio per egg mass were not influenced by the treatments (p>0.05; Table 4).…”

“…However, in that study, the diets did not contain synthetic amino acids, which may explain those results. Studies found that it was possible to include up to 5.6% ground whole sunflower seeds in layer diets without affecting performance or egg quality (Tsuzuki et al, 2003). However, sunflower meal is a byproduct from the oil industry that contains less energy and higher fiber than the ground whole seed.…”

Alternative feedstuffs, eggs quality, feed costs, poultry. ABSTRACTThe objective of this experiment was to evaluate the performance of 64-to 79-wk-old laying hens fed diets supplemented with an enzyme complex (EC) and containing increasing sunflower meal (SFM) levels. A total of 384 Hy-Line Brown layers were distributed according to a randomized block design in a 4 × 2 factorial arrangement (four levels of SFM, and inclusion or not of EC), with eight replicates of six birds each unit. The levels of SFM inclusion were 0, 8, 16 and 24%, utilized in two distinct diets. Diets were calculated to meet all the nutritional requirements of birds, except for the nutrients that would be made available by the nutritional matrix of the enzyme complex, with or without utilization of EC. The parameters analyzed were feed intake (g/bird/day), egg production (%/bird/day), egg weight, egg mass (g/ bird/day), feed conversion ratio per egg mass, feed conversion ratio per dozen eggs, body weight gain, egg components (yolk, albumen and eggshell) and the economic efficiency index (EEI). There was no interaction between EC addition and the SFM levels in the diet. The addition of EC in the diets of laying hens did not affect egg productive or components parameters. The increase in the SFM levels in the diet presented quadratic effect on egg production and feed conversion ratio per dozen eggs, with calculated optimal sunflower meal inclusion levels of 6.72% and 5.83%, respectively, for each parameter. The best economic efficiency per dozen eggs was obtained with the diet with 16.0% SFM and EC inclusion, whereas per egg mass with the diet with of 24.0% SFM and no EC addition.

“…Saponins and phytic acid present in most seed meals limit the availability of protein in the gut, with hens consequently prioritising maintenance of their body condition as opposed to laying eggs (Anhwange et al, 2004). Results from studies carried out by Tsuzuki et al (2003) and Shi et al (2012) observed that SSM supplementation had no effect on the ROL and this may validate the ANF justification since SSM is low in ANFs like phytic acid and saponins. These results are in line with Ahmed et al (2017) when it was reported that the inclusion of Moringa oleifera pod meal had no effect on the ROL.…”

The objective of the study was to determine how the partial supplementation of Moringa oleifera whole seed meal (MOWSM) would affect layer performance, egg quality and egg fatty acid profile. One hundred and forty-four Hy-Line hens in early-lay (20-weeks-old), with an average body weight of 1.45 kg were randomly allocated to four dietary treatments which were formulated to meet or exceed the National Research Council standards for brown-egg laying hens. Dietary treatments consisted of 0 (control), 1, 3, and 5% MOWSM. Layer performance was monitored over a period of 8 weeks. The inclusion of MOWSM in layer diets reduced feed intake, bodyweight, the rate of lay, egg weight, and egg mass. Yolk colour was significantly improved by 1, 3 and 5% inclusion levels, while the albumen height decreased. The albumen weight, yolk weight, eggshell weight, eggshell thickness, and egg shape index showed no statistical differences across all treatment groups. Similarly, the saturated fatty acid profile was also not affected. Palmitoleic acid decreased with the increase in MOWSM inclusion, whilst linolelaidic acid increased. The atherogenicity index was not affected by MOWSM inclusion, while the thrombogenicity index increased when compared to the control diet. It was concluded that, although MOWSM inclusion improved yolk colour, maintained external egg quality, and improved the fatty acid profile, the deleterious effect that it had on layer performance indicated that it may not be fed to early-lay hens at these respective levels.
