Enhancement of sperm motility and viability by turmeric by-product dietary supplementation in roosters

Abstract

Improving sperm motility and viability are major goals to improve efficiency in the poultry industry. In this study, the effects of supplemental dietary turmeric by-product (TBP) from commercial turmeric production on sperm motility, viability, and antioxidative status were examined in domestic fowl. Mature Rhode Island Red roosters were divided into two groups - controls (groupC) without TBP administration and test subjects (groupT) fed a basal diet supplemented with 0.8g of TBP/day in a temperature-controlled rearing facility (Experiment 1) and 1.6g/day under heat stress (Experiment 2) for 4 weeks. In Experiment 1, TBP dietary supplementation increased the sperm motility variables straight-line velocity, curvilinear velocity, and linearity based on a computer-assisted semen analysis, 2 weeks following TBP supplementation. In Experiment 2, using flow cytometry, sperm viability at 3 and 4 weeks following TBP supplementation was greater in Group T than C, and this increase was consistent with a reduction in reactive oxygen species (ROS) production at 2 and 4 weeks. The results of both experiments clearly demonstrate that dietary supplementation with TBP enhanced sperm motility in the controlled-temperature conditions as well as sperm viability, and reduced ROS generation when heat stress prevailed. Considering its potential application in a range of environments, TBP may serve as an economical and potent antioxidant to improve rooster fertility.

The Effects of Varying Combinations of Dietary Selenium, Vitamin E, and Zinc Supplements on Antioxidant Enzyme Activity, and Developmental and Histological Traits in Testicular Tissues of 1-Year-Old Native Turkish Ganders

“…Even if the testicular antioxidant capacity is low, antioxidant compounds in the testicular tissue can protect sperm against ROS [35]. Therefore, many studies have been conducted to increase and improve the antioxidant capacity in the testes [36][37][38]. Feeding programs provided to animals can affect reproductive activities and alter sexual behavior, morphology, and function of reproductive organs [39].…”

Review: Pengaruh Pakan Terhadap Kualitas Semen Ayam

“…Curcumin, merupakan komponen bioaktif utama kunyit, adalah antioksidan alami dan dapat bertindak sebagai agen anti-inflamasi, anti-apoptotik, anti-toksik dan antikanker (Chattopadhyay et al 2004). Yan et al (2017) melaporkan bahwa suplementasi tepung kunyit dalam pakan ayam jantan meningkatkan kualitas semen. Kazemizadeh et al (2019) melaporkan bahwa suplementasi curcumin pada dosis 30 mg/kg dalam pakan ayam jantan meningkatkan kualitas semen.…”

Natural Astaxanthin Improves Testosterone Synthesis and Sperm Mitochondrial Function in Aging Roosters

“…Recently, several studies have investigated the use of natural antioxidant compounds to prevent reproductive decline in aging roosters [ 16 , 17 ]. Astaxanthin (ASTA) is a member of the xanthophylls family of carotenoids, which can be extracted from a variety of microorganisms, phytoplankton, and marine organisms [ 18 ].…”
