Out on the next frontier of nutritional research will be the complete biochemical and physiological characterization of plant-derived foods that prevent or delay the development of chronic diseases in humans and animals. The chemical composition of many major crop products (seeds, flour, oil, leaves, etc.) have been determined, but the slow process of evaluating each compound alone or in mixtures for the biological function in nutrition and health of the animals that consume them has only just begun. Camelina, or false flax ( Camelina sativa L. Crantz), is an emerging oil seed crop in North America mostly used as a biodiesel fuel. The seeds contain up to 45 % oil, which is rich in polyunsaturated omega-3 and omega-6 fatty acids, as well as fat-soluble antioxidants such as the vitamin E-active tocopherols. Extraction of oil from camelina seeds by mechanical expeller yields a seed meal that consists of approximately 10 % residual oil, 45 % crude protein, 10 % soluble sugars, 13 % fiber, 5 % minerals, and 10 % phytochemical constituents such as glucosinolates, flavonols, lignans, phenolic acids as well as nucleic acids. The seed meal also contains a hydrophilic gum. While the oil fraction has been well characterized and its uses are growing, the seed meal has yet to be fully characterized for its potential use Mention of trade names or commercial products in this publication is solely for the purpose of providing specific information and does not imply recommendation or endorsement by the U.S. Department of Agriculture.

The main objectives of our study were to measure the major adipokines adiponectin, leptin and resistin in goat milk, to assess their interrelationships and to assess their relationships with the plasma and serum concentrations of total protein, cholesterol, total lipids, plasma C-reactive protein (CRP), milk somatic cell count (SCC), milk total aerobic colony and lactobacillus count, and milk components in lactating Saanen goats. The study was performed on eighteen lactating Saanen goats. Milk and blood samples were collected on days 20, 35, 50, 65 and 80 of lactation postpartum. The milk and plasma adiponectin levels on days 50, 65 and 80 postpartum were significantly higher than those on day 20. The milk and plasma leptin levels were lower on day 20 than on days 35, 50, 65 and 80. The milk concentrations of these major adipokines were positively intercorrelated. The milk and plasma concentrations of these three adipokines were also positively correlated. The plasma CRP concentrations correlated positively with milk leptin and resistin concentrations and inversely with milk adiponectin concentration. Milk adiponectin concentration was inversely related with its SCC. These data confirm that adiponectin, leptin and resistin are present in goat milk. The milk concentrations of these three adipokines were interrelated and interacted with the general inflammatory marker, CRP. The inverse relationship between milk adiponectin concentrations and its SCC suggests that variations in milk adiponectin might be involved in the udder health of lactating goats, but clinical trials are needed to support this hypothesis.

Obestatin is described as an anorexigenic peptide, and has adverse effects of ghrelin. It has no inhibitory effects on acute/chronic food intake, and it has been reported by several researchers. The role of obestatin in metabolism is still not clear. In the present study, the purpose is to determine the effects of chronically administrated obestatin. For this purpose, (1 µmol/kg; i.p.) or ghrelin (1 µmol/kg; i.p.) and food restriction (24h fast:24h fed) on plasma obestatin, ghrelin, leptin, insulin, cholecystokinin (CCK) and glucose levels, and body weight gain were investigated for 14 days in mice. Additionally, mice were treated with acute ip (100 nmol/kg) injections of obestatin or ghrelin to investigate the food consumptions, plasma obestatin and ghrelin levels to determine unknown acute effects of obestatin. Plasma ghrelin levels increased significantly in obestatin administered mice when compared with the control group for chronic treatment. This increase is consistent with immunohistochemical findings which claim that the number of ghrelin and obestatin immunopositive cells in fundus tissue of stomach are considerably high in obestatin treated animals. Plasma obestatin and ghrelin levels has shown an increase endogenously in food restricted mice, but plasma leptin and insulin levels have been found to be lower compared to the control group. Acute administration of obestatin caused a decrease in plasma obestatin level at 60 min after injection and had no effect on the reduction of food intake in each treatment time. These results imply that obestatin may not itself be involved in the metabolism regulation; however, obestatin accompanied by ghrelin may play a role in the long-term regulation of metabolism.

Kafkas Univ Vet Fak Derg, 23 (2): 283-288, 2017. DOI: 10.9775/kvfd.2016.16438 AbstractThe current study was conducted to evaluate the effects of dietary supplementation with rosemary volatile oil on performance, meat quality and selected plasma antioxidant parameters of quails. A total of 192 1-day-old Pharaoh (Coturnix coturnix Pharaoh) quails, including both males and females, were divided into three groups containing 64 quails and treated as follows: (1) a control group with 0 mg volatile oil/kg of diet; (2) 200 mg/kg rosemary volatile oil plus-RVO1; and (3) 250 mg/kg rosemary volatile oil plus-RVO2. The diets were prepared fresh for each treatment. The experiment was carried out for 42 days. Dietary treatments did not have any significant effect on live weight gain, feed intake, feed conversion rate, hot and cold carcass yield. There were significant differences for the plasma MDA level (P<0.01) and meat MDA level (P≤0.001) between the control and treatment groups. Plasma SOD activity not affected by addition of rosemary volatile oil but plasma GPx level was significantly (P<0.01) affected by dietary treatments. In conclusion, rosemary volatile oil may be a potential natural antioxidant for quails and used to retard lipid oxidation in animal diets to improve meat products quality and animal performance.

Poultry management is associated with light due to positive effects of photoreceptors on animal's growth, immunity and homeostasis. Colors influence the efficiency of poultry performance and behavior. Light-emitting diode (LED) can use for providing monochromatic light source.In this trial, two hundred Ross 308 broiler chicks were studied in four different light groups as follows; White (Control), Red (RL), green (GL) and blue (BL) during 42 trial days. At the end of the study, the serum Superoxide dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx) and malondialdehyde (MDA) enzyme activities were measured to evaluate the oxidant-antioxidant balance. The oxidant marker MDA was found the highest value in group RL (p:0.0001 ; 9.24±0.33). On the other hand, in group GL, all antioxidant parameters were found the highest value (p<0.05). Also, SOD and GPx values were increased in group GL (SOD: 150.61±9.14 ; GPx: 186.96±10.50) than BL (SOD: 139.29±5.19 ; GPx: 160.02±3.15) statistically (p<0.05). The results showed that red light may be a stressor, and on the contrary, green light may be a positive monochromatic color for growth, oxidant-antioxidant balance and homeostasis for broilers.

Glucosinolates are important bioactive molecules and widely found in Brassicaceae species (cress, brussels sprouts, mustard, broccoli, kale etc.). Depending on the amount of these vegetables consumed, both positive and negative metabolic effects from glucosinolate metabolites may occur. The aim of this study was to investigate inexpensive animal food sources that both increase weight gain and provide enhanced performance parameters without adversely affecting the animal’s health and metabolism; to evaluate dose adjustment of food containing glucosinolates in animals; and to evaluate changes in the biochemical and performance status of chickens on the glucosinolate containing diets. Day-old Ross 308 broiler line chicks (624) were divided into 1 control and 3 treatment groups. Cress seed (Lepidium sativum) was added 0.05% for the first treatment group (group 1, 10g/kg), 0.10% for the second treatment group (group 2, 20g/kg) and 0.15% for the last treatment groups (group 3, 30 g/kg) to the diet. Serum samples were evaluated for serum glucose, adiponectin, leptin, growth hormone, estradiol and cortisol levels. Feed intake, live body weight gain and feed conversion ratio were investigated for performance parameters. The results showed that dietary cress seed supplementation as feed additive (10, 20 and 30 g/kg) did not significantly improve the dietary performance, or carcass parameters of broiler chickens. Feed intake was the highest in group 2 (20g/kg), female live weight was the highest in group 2 (20 g/kg) and 3 (30 g/kg).
