| Abstract |
The present study consists of two experiments. In experiment 1, a total of 120 weaned piglets (Yorkshire × Landrace) (7.3 ± 1.9 kg) were allocated to five treatments, and four replications (pens) with six piglets/pen. In experiment 2, 40 male pigs (23.0 ± 2.2 kg) were allocated to five treatments and eight replications (individual pens). In both experiments, the control diet contained fish meal (FM) as the sole protein supplement (CPH0), while the experimental diets consisted of four different diets in which crude protein (CP) from FM in CPH0 was replaced by the CP from catfish (Pangasius hypophthalmus) by-product protein hydrolyzate (CPH) at four different levels: 100 % (CPH100), 75 % (CPH75), 50 % (CPH50) and 25 % (CPH25). The results in experiment 1 showed that the highest average daily gain (ADG) over the 5-week period after weaning was recorded for piglets on CPH100 (307 g/day), and the lowest for piglets fed CPH0 (287 g/day) (P < 0.01). Feed conversion ratio (FCR) was lower in CPH100 (1.43 kg feed/kg gain) than in CPH0 (1.51 kg feed/kg gain) (P < 0.01). The piglets fed CPH100 were less affected by diarrhoea (6.55 %) than piglets fed the control diet CPH0 (17.3 %) after weaning, and faecal scores were also lower. In experiment 2, ADG was lowest in CPH0, and the cost/gain in pigs fed CPH100 was lowest in both weaning and growing pigs. In conclusion, it is possible to replace up to 100 % of the FM by CPH in diets for weaning and growing pigs, resulting in improved ADG and FCR, lower feed cost/gain as well as reduced diarrhoea incidence and improved faecal score. |

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 17 May 2017.
All research outputs
#19,440,618
of 23,911,072 outputs
Outputs from Tropical Animal Health and Production
#763
of 1,384 outputs
Outputs of similar age
#289,583
of 371,274 outputs
Outputs of similar age from Tropical Animal Health and Production
#7
of 17 outputs
Altmetric has tracked 23,911,072 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,384 research outputs from this source. They receive a mean Attention Score of 2.3. This one is in the 33rd percentile – i.e., 33% 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 371,274 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 17 others from the same source and published within six weeks on either side of this one. This one is in the 47th percentile – i.e., 47% of its contemporaries scored the same or lower than it.
