Parental Age is not a Decisive Factor Influencing Gut Development, Nutrient Utilization, or Growth Performance in Response to Supplementation with Multi-Enzyme Preparations in Broiler Offspring.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Progeny from older breeder hens exhibit higher feed intake but less efficient nutrient utilization than those from younger breeders. Multi-enzyme supplementation (MES) can serve as a practical dietary intervention to address this challenge. This study aimed to assess the effect of broiler breeder hen age (BBA) and MES on growth performance, gastrointestinal tract traits, nutrient digestibility, and cecal microflora profile of broilers. A total of 780 one-day-old straight-run Ross 308 chicks were arranged in a 2 × 3 factorial design according to two breeder ages (39 or 60 weeks) and three types of diet: a basal diet (CNT), basal diet supplemented with a commercial multi-enzyme product (AVZ, or Avizyme 1500
