| Abstract |
High costs of conventional protein feed sources including soybean meal (SBM) generated the need for finding other alternatives. Thus, the present study was designed to evaluate the impact of graded replacements of SBM by sunflower seed meal (SFM) with or without enzyme supplementation on growth performance, digestive enzymes, carcass traits, and blood profile of broiler chickens. A total of 240 unsexed 1-week-old broiler chicks (Hubbard) were randomly divided into eight treatment groups of 30 chicks each in five replicates each of six chicks in a factorial design (4 × 2) arrangement, including four levels of SFM (0, 25, 50, and 75% replacing SBM) and two levels of enzyme (0- or 0.1-g/kg diet) supplementation. Performance traits including feed conversion ratio, body weight, and weight gain were significantly (P < 0.01) improved with increasing SFM up to 50% substitution for SBM or with enzyme supplementation in broiler diet during the experiment. However, feed intake of broiler chicks was decreased with enzyme supplementation (P < 0.05). The activities of digestive enzymes (protease and amylase) were significantly (P < 0.05) influenced and enhanced by SFM and enzyme inclusion in diets, respectively. The activities of protease and amylase were improved with SFM diet supplemented with 0.1 g/kg enzyme in comparison with those with the un-supplemented diet. The evaluated carcass traits were not statistically (P > 0.05) influenced by feeding SFM meal or enzyme addition. Biochemical blood parameters were significantly (P < 0.01) affected by SFM, enzyme, or their interaction in broiler diets, except for globulin that was not affected by dietary enzyme. It is concluded that increasing SFM level in the diet up to 50% replacing SBM with the supplementation of enzyme improved the growth performance and enhanced positively carcass traits as well as the activity of digestive enzymes in broiler chickens. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 March 2017.
All research outputs
#21,420,714
of 23,911,072 outputs
Outputs from Environmental Science and Pollution Research
#7,000
of 9,883 outputs
Outputs of similar age
#273,546
of 311,580 outputs
Outputs of similar age from Environmental Science and Pollution Research
#124
of 173 outputs
Altmetric has tracked 23,911,072 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,883 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 311,580 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 173 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
