Significant effect of NSP‐ase enzyme supplementation in sunflower meal‐based diet on the growth and nutrient digestibility in broilers

Abstract

The response of broiler chickens to 3 levels of sunflower meal and 2 levels of NSP-ase enzyme combination (with and without) was investigated in 3 × 2 factorial arrangement under complete randomized design (CRD). A total of 240 Hubbard broiler chicks were fed on practical mash diets having 2950 kcal of ME and 21% CP from 1 to 42 days of age. The BW gain was not significantly reduced when 25% SFM was added in the diets during 1 to 42 days of age. Supplementation of NSP-ase in broiler diets (day 1-42 overall) demonstrated non-significant differences (p < 0.05) across the treatments in terms of FI and BWG. The difference in feed:gain at 15% or 20% SFM was observed to be non-significant. Replacement of SBM with SFM or inclusion of SFM at higher level (25%) increased/deteriorated FCR. The addition of exogenous NSP-ase showed a significant improvement (p < 0.01) in feed:gain. The improvement was clearly demonstrated when SFM was added to the experimental diet at 15% or even 20%. Supplementation of NSP-ase at the 25% inclusion level could not, however, sustain the beneficial effect, which was possibly due to excessively high dietary CF. No difference was noted across the treatments regarding carcass response. Relative gizzard weight and intestinal weight were observed to be improved in birds consuming higher levels of SFM (p = 0.00). The digestibility of CF was observed to improve when SFM was used at 20% and 25% in the diets. No improvement in the digestibility of CF was observed with NSP-ase supplementation, which meant other factors were clearly involved. Supplementation of NSP-ase improved FCR up to 20% SFM. At 25% SFM, no improvement in the digestibility of CF was observed with NSP-ase supplementation.

Worldwide Mycotoxins Exposure in Pig and Poultry Feed Formulations

“…Replacing soybean meal with sunflower meal at high rates is possible in different poultry species [62,63,64,65]. The beneficial effect of enzyme supplementation appears to vary [66,67,68]. Sunflower meal can also be used in pig feed, although some studies suggest that amino acid digestibility was lower than in soybean meal [69,70,71,72].…”

Effect of Different Dietary Inclusion Levels of Sunflower Meal and Multi-Enzyme Supplementation on Performance, Meat Yield, Ileum Histomorphology, and Pancreatic Enzyme Activities in Growing Quails

“…The results of previous studies stated that SFM could be included up to 15% [8,19] and 20% levels [10,11] in the diet with no negative effects on performance parameters such as BWG or FCR in broilers. In addition, Christaki et al [29] noted that the BW, FI, and FCR of quails were not significantly affected by dietary SFM ranging from 3.5% to 6.5% levels.…”

“…While some researches indicated that SFM can be used up to 15% in broiler diets without negatively affecting performance [7,8], some studies reported that it can be used at higher levels [9,10], especially with the addition of enzymes [11]. On the contrary, there were studies reported that the use of 10% and more SFM in broiler diets negatively affected the growth performance [12][13][14][15].…”

“…Therefore, the addition of enzymes to diets containing raw materials such as SFM containing NSP increases digestion and consequently improves the performance of the birds. Bilal et al [11] stated that the addition of enzymes to the diet containing 20% SFM improved the performance of broilers.…”

Growth Performance, Carcass Traits and Economics of Broiler Chickens as Affected by Dietary Sunflower Meal

“…Sunflower meal (SFM) is a by-product of sunflower oil industry, and has been increasingly added to animal diets (Ali et al, 2011;Bilal et al, 2016). Moreover, SFM is potentially one of the most important protein sources in the world, and particularly in our country.…”
