Agrifood by-products contain nutrients and bioactive compounds that can be used in the diets of livestock - thereby value-adding to an otherwise waste product of environmental and economic significance. This study investigated the effect of dietary pomegranate pulp in the total mixed ration of Ghezel lambs, evaluating its effect on growth performance, blood parameters, carcass traits, as well as meat quality and shelf life. 3-month-old Ghezel lambs (individually housed, = 8) were randomly assigned to be either non-supplemented (control) or supplemented with 100 g/kg DM of sun-dried pomegranate pulp for 28 days, post-adjustment.

This study evaluated the changes in calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), sodium (Na), phosphorus (P), strontium (Sr) and zinc (Zn) values in goose egg yolk during the incubation period. This study was conducted on a completely random selection using 200 fertile eggs from a local flock of geese. A selection of 30 fertile eggs were randomly sampled on days 0, 9.

The objective of this study was to investigate the effects of feeding Amaranthus hybridus chlorostachys grain (AG) with (+E) and without enzyme (−E) on performance, egg quality, antioxidant status and lipid profile of blood serum and yolk cholesterol in laying hens. A total of 960 white leghorn (Hy-line W-36) commercial layers (56 weeks) were divided into 10 groups with 8 replicates per group (12 birds per replicate, including 3 adjacent cages with 4 birds each). A completely randomized design was implemented with a 5 × 2 factorial arrangement of treatments consisting of five levels of AG (0, 100, 200, 300 and 400 g/kg) and two levels of multienzyme complex addition (0 −E and 0.

Higher long-chain polyunsaturated fatty acids contents in roosters' sperm plasma membrane along with age-related decrease in antioxidant defense make the spermatozoa very susceptible to lipid peroxidation. Ginger root contains abundant amounts of gingerol, shogaols, gingerdiol and other active compounds, which known as antioxidant compounds to enhance semen quality. The goal of the study was to evaluate the effect of dietary supplementation of ginger root on semen quality, blood chemistry, immune response, testicular histology and reproductive performance of Ross-308 breeder roosters from 47 to 60 weeks of age.

Rooster semen contains high content of long-chain polyunsaturated fatty acids; therefore, spermatozoa are very susceptible to lipid peroxidation. Carob fruit (CF) contains abundant amounts of flavonoid known as natural antioxidants and semen enhancers. The purpose of the study was to investigate the effect of dietary supplementation of CF on semen characters, blood parameters, immune response, testicular histology, and reproductive performance of aging broiler breeder roosters.

The present study was carried out to investigate the effect of dietary vitamin E on growth performance, cellular immunity, carcass characteristics, and meat quality in geese. Sixty-four one-day-old male geese were selected from 1200 goose chicks with the same average body weight (92.5 ± 2.
