Effects of parsley supplementation on the seminal quality, blood lipid profile and oxidant status of young and old male rabbits

Abstract

Abstract:The high unsaturation levels of spermatozoal membrane make it very susceptible to oxidative damage and this problem increases with advancing age. In this study, the aim is to investigate whether parsley seed (PS) has a protective effect on semen quality, serum lipid profile and antioxidative status of old and young bucks. Male rabbits (n= 36) (18 young 9-12 mo old and 18 old 36-42 mo old) were each assigned to 3 dietary treatments (a control and 2 levels of PS: 0.3 and 0.6 kg/100 kg diet) to evaluate the ability of parsley to enhance bucks' reproductive status. Most of the studied traits were adversely affected by age of rabbit bucks. On the other hand, the inclusion of PS significantly boosted ejaculate volume and improved mass motility concentration and total sperm output. Seminal plasma and blood serum total antioxidant capacity increased, while serum lipid peroxidase decreased with parsley treatments. In conclusion, dietary supplementation of parsley seed alleviates most semen quality parameters and counteracts oxidative stress, especially with the advance of age (seminal plasma and blood serum of total antioxidant capacity and malondialdehyde.

Performance, haemato-biochemical indices and antioxidant status of growing rabbits fed on diets supplemented with Mucuna pruriens leaf meal

“…Mucuna pruriens leaves harvested fresh within the premises of ATDT&RF, The Federal Polytechnic, Ado Ekiti, Nigeria were chopped, air-dried under the shed for 7 d, milled with a 2 mm hammer mill to MLM and analysed for tannin (Van-Burden and Robinson, 1981), terpenoid (Ferguson, 1956), cardiac glycoside (Ferguson, 1956), saponin (Shad et al, 2013), steroid (Edeoga et al, 2005), alkaloid (Harborne, 1973), flavonoid (Shad et al, 2013), Ferric reducing antioxidant property (FRAP) (Pulido et al, 2002) and 2, 2-diphenyl-1-picrylhydrazyl hydrate (DPPH) (Gyamfi et al, 1999) (Table 1). A basal diet was formulated to support optimal rabbit growth (de Blas and Mateos, 2010) ( Table 2).…”

Effects of potato peel extract on semen quality, sex hormones and immunity of rabbit bucks under intensive breeding system

“…Follicle-stimulating hormone increases the number of cells passing through meiosis and spermatogenesis, thus increasing semen concentration; or to the improvement in testosterone production (which is essential for the sperm production (Walker, 2009)) with the antioxidant compounds of PPE that protects spermatocytes stages from apoptosis, as a consequence, sperm production increased by improving oxidative stability (Attia & Kamel, 2012). The significant reduction in dead sperm percentage by PPE administration may be due to protect lipids membrane of sperm cell by preventing their oxidation and maintaining enough level of antioxidant compounds (Zeweil & El-Gindy, 2017).…”

Growth performance and antioxidant status of growing rabbits fed on diets supplemented with Eucommia ulmoides leaves

“…The 3 kinds of feeds (control, EUL1, and EUL5) were provided by the Tai'an Rabbit Industry Co., Ltd., and contained the appropriate nutritional and chemical composition to support optimal growth of meat rabbits (Table 1) (De Blas and Mateos, 1998;El-Gindy and Zeweil, 2017). When EUL were added, they were first mixed with 1 kg of basal diet, and additional EUL powder was gradually added during mixing to ensure a uniform distribution of EU in the basic feed, which was then pelleted to 4 mm diameter.…”
