Reported was an investigation of the effect of vitamin E (Vit.E) and corn oil on semen traits of male Japanese quail (Coturnix coturnix japonica). From 8 to 20 wk of age, birds were raised on corn-based diets supplemented with corn oil (0 and 3%) and Vit.E (National Research Council (NRC) recommended 25mg/kg/day/dry matter and 150 mg/kg/day/dry matter) in a 2×2 factorial manner. The diet was su...

Growth-related skeletal diseases in young horses have been associated with high planes of nutrition, although the mechanisms underlying such an association have not been determined. It is likely that nutrition-induced effects on growth rate or growth quality involve the endocrine system. Hormonal and metabolic responses to the ingestion of meals containing either 80% (diet A) or 160% (diet B) o...

Graded levels of a trace mineral premix containing an organic (Bioplex) source of Cu, Fe, Mn, and Zn was evaluated with additional treatments containing organic Zn or Fe. Grower-finisher pigs were fed from 25 to 115 kg BW. The number of pigs in the experiment, the breeding/genetics of the pigs, the management, and the average age of the pigs were previously reported. The experiment was conducte...

in this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of leghorn-type laying hens (hy-line w-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. the treatment groups were: 1) control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...

Epidemiologic studies have shown that diabetics receiving the biguanide metformin, as compared with sulfonylureas or insulin, have a lower incidence of breast cancer. Metformin increases levels of activated AMPK (AMP-activated protein kinase) and decreases circulating IGF-1; encouraging its potential use in both cancer prevention and therapeutic settings. In anticipation of clinical trials in n...

This study was designed to investigate the effects of dietary oregano essential oils on 150 30-week-old Hy-Line Layers’ productive performance, egg quality characteristics, cecal microbiota, digestive enzyme activities, mucosa structure of the duodenum and jejunum and glucose and small peptides transporters expression in the duodenum and jejunum. All hens were allocated into one of five differe...

The carcinogenesis potential of ripazepam , a benzodiazepine derivative, was studied in mice and rats for 78 and 104 weeks, respectively. Groups of 50 male and 50 female CD1 mice and CD rats each were given doses of 15 and 150 mg/kg of ripazepam in the diet. Survival rates were adequate for statistical analysis. Significant suppression of body weight gains occurred in rats but not in mice given...

A number of retinoid X receptor (RXR) agonists have proven to be highly effective in preventing methylnitrosourea (MNU) induced mammary cancers. However, these agonists have side effects; particularly causing an increase in serum triglyceride levels. A series of ligands for RXR were designed based on computer modeling to the ligand binding domain (LBD) of the RXR receptors and on structure-acti...

Supplementation of pelleted feeds (30% crude protein) consisting of practical ingredients with 250, 375 and 500 mg Cholymbi/kg diet resulted significantly improved the growth of common carp, Cyprinus carpio. Highest final average weight was recorded with diet containing 500 mg Cholymbi/kg. Feeding Cholymbi to fish showed increased carcass protein and fat. Gut protease and hepatopancreas amylase...
