Nutritional Level and Type of Feed on the Reproductive Performance of Ewe and Its Effects on 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
The amount and source of nutrition are important factors that influence an ewe's reproductive ability, but the effects of diet on the reproductive performance of its offspring are unclear. This study aimed to investigate the impact of maternal nutrition (level of nutrition and source) on the reproductive performance of ewes and their female lamb offspring. Seventy-two Dorper × Santa Inês ewes were allocated in a completely randomized block design, in five treatments: CTL (n = 14) with 100% of requirement, and the energy source was corn; RES (n = 14) with 90% of predicted requirement, and the energy source was corn; SUPP (n = 15) with 110% of requirement, and the energy source was corn; CR (n = 15) treatment SUPP plus chromium propionate; and FAT (n = 14) treatment SUPP plus calcium salts of palm oil. Non-parametric data were evaluated using the Fisher exact test, and parametric data were evaluated using the Tukey test, both at a 5% significance level. There was no difference in pregnancy rate (p = 0.1944) or prolificacy (p = 0.5729) among the treatments; however, the CR diet resulted in a faster return to estrus after lambing (p < 0.001). The RES diet decreased lamb survival (p < 0.005) and reduced offspring reproductive potential. Using chromium positively affected the reproductive parameters of female offspring, whereas FAT adversely affected them. In conclusion, the source and level of dietary energy influence fetal programming in ewes. The restriction negatively affected the reproductive performance of the offspring, and supplementation with chromium propionate improved it.
