“…Similar results were found by Ahmed et al (2017) when EW was not affected by the inclusion of Moringa oleifera pod meal in layer hen diets. Concurring results were also found when Ahmed and Abdelati, (2009) and Shi et al (2012) reported that EW was not affected by the presence of LLS and SSM in the layer diet, respectively. Egg weight is influenced mainly by genetics, environment, and hen age (Albrecht, 2011).…”

“…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.…”

“…Soybean meal is the main crude protein (CP) source that is used, as it contains adequately balanced amino acids and satisfactory essential fatty acids (FAs) to satisfy the laying-hen nutritional requirements (Hammershoj & Steenfeldt, 2005;Shi et al, 2012;de Morais Oliveira et al, 2016). The exceptional performance of soybean meal has increased its demand in the animal feed industry, which has subsequently led not only to its scarcity but also to an increase in its price (Laudadio et al, 2011;Abbas, 2013).…”

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.

“…No significant differences (P>0.05) were observed among treatment groups in the productive performance and egg quality criteria (egg weight, shell strength, egg specific gravity, shell thickness, shell color, shell percentage, yolk percentage, albumen percentage, yolk color and Haugh units) as well as the levels of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids in yolks of laying hens, when layer fed diets contained 0, 8.26, 16.52, and 24.84% SFM replacing SBM (Shi et al, 2012). However, Results from this study reported that the percentage of C17:0 and levels of egg yolk cholesterol of layers in the experimental groups were lower than those of layers in the control group (P < 0.05).…”

| The benificial application of untraditional feedstuffs such as sunflower meal (SFM) in animal and poultry nutrition in developing countries has received considerable attention. SFM is a by-product of sunflower oil industry, and has been increasingly added to animal and birds diets. Moreover, SFM is potentially one of the most important protein source in the world. Nowadays, it is well known that feed represents the main cost of animal and poultry production and accounts about 75% of the total cost. The increasing feed ingredients price of poultry nutrition caused to look closely at agricultural by-products which are less cost than traditional ingredients. Thus, the waste residues of crops, vegetables and fruits after harvesting and processing could be used as sources of protein, energy and other nutrients in feeding animals and poultry. Reports from variuos laboratories on the using SFM as feed ingredient for poultry are discussed in this review. Based on the findings presented, SFM is an acceptable feed componentof poultry rations and can be fed at 25% in broiler and 20% in layer diets. However, replacement of soybean meal (SBM) with SFM may affect dietary inclusions of essential amino acids, and use of synthetic lysine may need to be increased. The high levels of SFM in poultry diets can be used successfully with appropriate diet formulation adjustments for energy and amino acids particularly lysine and methionine. This compilation with its valubale information would be beneficial for researchers, chemists, feed and food industry, and certainly could help to promote the usage of SFM in poultry production.

“…However, in addition to the fluctuation in supply and seasonal scarcity in some parts of the world, the price of SBM has been increasing over the years (Shi et al, 2012;Pettersson & Pontoppidan, 2013). It is therefore more effective to use full-fat SBM to replace both commercial SBM and the oil in the diets for broilers (Popescu & Criste, 2003).…”

A 3 * 3 factorial study was used to evaluate the feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR) of broilers fed on the test diets. The commercial soybean meal (SBM) was replaced by raw, full-fat soybean meal (RSBM) at 0, 10 or 20%, equivalent to 0, 30 and 60 g/kg of diet, respectively, and the microbial protease was also supplemented in diets at 0.1, 0.2 or 0.3 g/kg, equivalent to ~7500, 15000 and ~22500 PROT/kg of diet, respectively. Microbial phytase (1000 FYT/kg) was uniformly added to each diet, which was fed to six replicate groups, with nine birds per replicate. Samples of test-ingredients and test-diets, after mixing, were also subjected to chemical analysis, prior to being used, to assess the nutritional compositions, particularly anti-nutritional factors. As the result of this study, the analysed concentrations of trypsin inhibitors (TI) in the diets ranging between 1730.5 and 9913.2 TIU/g. Increasing the levels of RSBM in the diets reduced the FI, during 1 to 35 d of age. Except in the starter phase, increasing the level of RSBM had no significant effect on BWG. When protease was added to the diets, the BWG was significantly improved during the periods of 1 -10 d, 1 -24 d and 1 -35 d. Feed efficiency was decreased by increasing the level of RSBM (1-10 d). Neither increasing levels of RSBM nor protease affected the yield of any meat part at d 35. The relative weight of the small intestine at d 10 increased with rising levels of RSBM, but was reduced when protease was added to the diets. In conclusion, commercial SBM could be replaced by RSBM up to 20% in diets for broilers when the test microbial protease is supplemented.
