Abstract

Objective: This study aimed to investigate the impact of dietary supplementation with flaxseed oil on the morphological characteristics of semen in male ostriches. Method: The experiment was conducted at the Babylon Reserve for Ostrich, Falcon, and Deer Breeding, Babylon Province, Iraq, using 27 sexually mature ostriches divided into three treatment groups with three replicates each, organized under a family-based system (two females and one male per replicate). Birds were housed in specialized pens, with males separated from females from the beginning of the trial, and all were provided a standardized diet containing 17.34% crude protein and 2740.56 kcal/kg metabolizable energy. Treatments included a control diet and diets supplemented with 1% or 2% flaxseed oil. Semen traits assessed included ejaculate volume, sperm concentration, and packed sperm volume. Results: Supplementation with flaxseed oil at both inclusion levels led to statistically significant and highly significant improvements in most evaluated semen parameters compared with the control. Novelty: These findings provide new evidence that flaxseed oil, as a rich source of Omega-3 fatty acids, can enhance reproductive performance in male ostriches, offering a natural nutritional strategy to improve fertility and productivity in ostrich farming systems.

Abstract

Objective: This study aimed to investigate the biological effects of dietary supplementation with mulberry and artichoke leaves on mitigating the negative impacts of heat stress in laying hens. Method: A total of 144 Lohmann Brown laying hens were randomly assigned to six dietary treatments (24 hens per treatment, three replicates of eight hens each). The treatments consisted of a basal diet supplemented with artichoke leaf powder, mulberry leaf powder, or their combination at inclusion levels of 0, 1, 1.5, 1, 1.5, and 1.5+1.5 g/kg of feed, respectively. The trial lasted four months, during which blood samples were collected biweekly from each replicate, and monthly averages were analyzed to evaluate liver enzyme activities (AST, ALT, ALP) and oxidative stress markers (MDA, SOD). Results: The findings revealed that dietary supplementation with mulberry and artichoke leaves, individually or in combination, significantly alleviated the adverse effects of heat stress, as reflected by improved oxidative status and more favorable liver enzyme activity. Novelty: This study highlights the functional potential of natural plant-based additives, such as mulberry and artichoke leaves, as sustainable nutritional strategies to enhance resilience and maintain performance of laying hens under heat stress conditions.
