This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. The results of experiment have shown that egg weight was increased by supplementation of 12 g kg-1 feed additive wherea...

Intraspecific competition and food shortage due to high population density during early life can have a profound effect on adult fitness. Organisms often mitigate negative effects of by adjusting resource allocation morphological life-history traits. In Lepidoptera with short-lived adults that do not feed, it is predicted females developed from dense larval aggregations invest more in reproduct...

Natural deep eutectic solvents (NADES) are a third type of liquids, apart from water and lipids. NADES show promise as drug carriers in dermal formulations or for local administration the oral cavity due to their low toxicity, tunability biodegradability well solubilizing stabilizing properties. However, thorough investigation effects biological system is needed. The present study aimed investi...

The purpose of this study was to examine the effects quail egg yolk extenders in cryopreservation cockerel semen. Ten Venda cockerels were chosen randomly and semen collected twice a week with two-day rest period using an abdominal massage technique. Immediately following collection, samples evaluated for microscopic parameters (sperm cell motility, viability, morphology, abnormalities) as well...

in this study, the effects of culban seed (vicia peregrine l.) on live body weight, feed intake, feed efficiency, egg production, egg quality characteristics, egg yolk fatty acid profiles and yolk cholesterol content in laying hens were investigated. the experiment consists of seven treatment groups with ten replications containing one laying hen in each and for 32 weeks old seventy laying hen ...

Background Low-density lipoproteins (LDL) is known to protect boar sperm during freezing–thawing, but little information is known about the effects of LDL extracted from different avian egg yolks on post-thaw boar semen quality. The purpose of this study was to compare and analyze the effects of LDL at various concentrations and different species on boar sperm quality after freezing–thawing. Ma...
