Poor environmental conditions experienced during early development can have negative long-term consequences on fitness. Animals can compensate negative developmental effects through phenotypic plasticity by diverting resources from non-vital to vital traits such as spatial memory to enhance foraging efficiency. We tested in young feral pigeons (Columba livia) how diets of different nutritional value during development affect the capacity to retrieve food hidden in a spatially complex environment, a process we refer to as "spatial memory"...

Animal production in China has achieved considerable progress and contributes to46%of the total agriculture output value of the country. However, this fast expansion of animal production has led to environmental pollution. In this article, we review the status of soil, water, and air pollution associated with animal production in China and analyze the main sources of the pollutants. The government has promulgated regulations and standards, and effective models and technologies have been developed to control pollution during the last 10 years...

Only a handful of non-human animals are known to grow their own food by cultivating high-yield fungal or algal crops as staple food. Here we report an alternative strategy utilized by an omnivorous marine worm, Hediste diversicolor, to supplement its diet: gardening by sprouting seeds. In addition to having many other known feeding modes, we showed using video recordings and manipulative mesocosm experiments that this species can also behave like gardeners by deliberately burying cordgrass seeds in their burrows, which has been previously shown to reduce the loss of seeds to water...

The aim of this study was to investigate the effects of dietary vitamin E deficiency on systematic pathological changes and oxidative stress in fish. A total of 320 healthy common carp (Cyprinus carpio) were randomized into four groups; the control group was fed a basal diet supplemented with 100 IUkg-1 of vitamin E, while the three experimental groups were fed the same basal diet with reduced vitamin E content (0, 25, or 50 IUkg-1). Findings showed that fish in the experimental groups mainly presented with sekoke disease, exophthalmia, leprnorthsis, and ascites...

Traditionally, poultry farmers aimed to produce birds with high body weight and feed conversion ratio. However, in line with current developments, there are other traits that must be taken into account as well. These include producing poultry meat with lower body fat content and improving the nutritional quality of the poultry meat to appeal to consumer requirements. The interrelated importance of human diet and health status is an ancient subject. Human foods as a lifestyle factor is involved in the incidence of many types of diseases, such as cardiovascular diseases and cancer...

Aquatic environments vary widely in aspects other than their physicochemical properties that could alter the toxicity of novel contaminants. One factor that could affect chemical toxicity to aquatic consumers is their nutritional environment as it can strongly affect their physiology and life history. Nutrition has the potential to alter an organism's response to the toxin or how the toxin interacts with the consumer through its food. Here we determined how growth and survival responses of Daphnia to an emerging contaminant, silver nanoparticles (AgNPs), are affected by the presence of food and its stoichiometric food quality...

Different monounsaturated fatty acid (MUFA) species have distinct pathophysiological activities. cis-Palmitoleic acid (16:1n-7) was previously reported to improve insulin sensitivity in animal studies. The proportions of hepatic MUFAs are generally considered to reflect changes in the activities of fatty acid modifications (∆9 desaturation and fatty acid elongation). However, hepatic levels of 16:1n-7 are markedly lower than those of oleic acid (18:1n-9). Nevertheless, no convincing explanation has yet been provided for the low level of 16:1n-7...

BACKGROUND/OBJECTIVES: Few studies have examined the factors explaining the variability in fat and carbohydrate intake during infancy. We aimed to describe infants' fat and carbohydrate intake and analyse the associations with infant and maternal characteristics and feeding practices. SUBJECTS/METHODS: This study included 1275 infants aged 8 months from the French EDEN mother-child cohort. Carbohydrate intake, fat intake, added fat (vegetable oils and animal fats) and added sugar (honey, white sugar, brown sugar, jam and sweetened beverages) consumption were calculated at 8 and 12 months...

The release of phosphate from inorganic and organic phosphorus compounds can be mediated enzymatically. Phosphate-releasing enzymes, comprising acid and alkaline phosphatases, are recognized as useful biocatalysts in applications such as plant and animal nutrition, bioremediation and diagnostic analysis. Metagenomic approaches provide access to novel phosphatase-encoding genes. Here, we describe a function-based screening approach for rapid identification of genes conferring phosphatase activity from small-insert and large-insert metagenomic libraries derived from various environments...

: Infection and inflammation impede efficient animal productivity. The activated immune system ostensibly requires large amounts of energy and nutrients otherwise destined for synthesis of agriculturally relevant products. Accurately determining the immune system's in vivo energy needs is difficult, but a better understanding may facilitate developing nutritional strategies to maximize productivity. The study objective was to estimate immune system glucose requirements following an i...

REVIEW
You-Lin Tain, Julie Y H Chan, Chien-Ning Hsu
Hypertension originates from early-life insults by so-called "developmental origins of health and disease" (DOHaD). Studies performed in the previous few decades indicate that fructose consumption is associated with an increase in hypertension rate. It is emerging field that tends to unfold the nutrient-gene interactions of maternal high-fructose (HF) intake on the offspring which links renal programming to programmed hypertension. Reprogramming interventions counteract disturbed nutrient-gene interactions induced by maternal HF intake and exert protective effects against developmentally programmed hypertension...

Cancer cachexia remains a leading cause of morbidity and mortality worldwide, despite extensive research and clinical trials. The prominent clinical feature of cancer cachexia is the continuous loss of skeletal muscle that cannot be fully reversed by conventional nutritional support, and that leads to progressive functional impairment. The mechanism underlying muscle loss in patients with cachexia is poorly understood. The present study analyzed 21 cancer patients with or without cachexia, and demonstrated that mitofusin-2 (Mfn2) was downregulated in the rectus abdominis of patients with cachexia, which was associated with body weight loss...

Leptin is a hormone that mediates the effect of the metabolic state on several biological functions, including reproduction. Leptin affects reproductive functions via alterations in the release of hormonal regulators. However, the extent to which caloric restriction (CR) can affect the complex processes of reproduction by other mechanisms, such as altering ovarian functions via direct binding/response to leptin, is unknown. Therefore, the aim of the present study was to show basic ovarian cell functions and CR on the response of ovarian cells to leptin...

Gossypol is known to be a polyphenolic compound toxic to animals. However, its molecular targets are far from fully characterized. To evaluate the physiological and molecular effects of gossypol, we chose turbot (Scophthalmus maximus L.), a carnivorous fish as our model species. Juvenile turbots (7.83 ± 0.02 g) were fed with diets containing gradient levels of gossypol at 0 (G0), 600 (G1) and 1,200 (G2) mg/kg diets for 11 weeks. After the feeding trial, fish growth, body protein and fat contents were significantly reduced in G2 group compared with those of G0 group (P< 0...

Gut microbiota is involved in obesity, metabolic syndrome and the progression of nonalcoholic fatty liver disease (NAFLD). It has been recently suggested that the flavonoid quercetin may have the ability to modulate the intestinal microbiota composition, suggesting a prebiotic capacity which highlights a great therapeutic potential in NAFLD. The present study aims to investigate benefits of experimental treatment with quercetin on gut microbial balance and related gut-liver axis activation in a nutritional animal model of NAFLD associated to obesity...

We hypothesized that single-parent children (SPC) are retarded in growth compared with both-parent children (BPC), and that motherless children (MC) are affected differently from fatherless children. Moreover, the growth disparity between SPC and BPC might be attributed to a deficient nutrient intake. Data from 2967 children between the ages of 2 and 18 years were extracted from 4 recent waves (2004, 2006, 2009, and 2011) of the China Health and Nutrition Survey to compare the growth status of SPC and BPC and to investigate the association between growth indicators and nutrition status...

REVIEW
Bobbi J Conner
Hypoalbuminemia is common and associated with a variety of disease processes, including those leading to systemic inflammatory response syndrome, gastrointestinal disorders, hepatic disorders, and glomerular diseases. Some animals develop clinical signs directly caused by low serum albumin concentration. There is strong evidence that hypoalbuminemia is associated with worse outcomes; however, evidence justifying albumin supplementation is lacking. Severe adverse events are frequently reported with administration of human serum albumin and there is little evidence of benefit from other products...

Companion birds are increasingly living longer due to improved husbandry, nutrition, and veterinary care. As a consequence, a growing number of geriatric disease conditions are diagnosed and managed by veterinarians. Awareness of bird owners of diagnostic and treatment options for neoplastic diseases in humans and domestic animals has led to increasing demand to provide advanced diagnostic and treatment modalities for companion birds diagnosed with neoplasia. Treatment remains challenging in many companion birds due to the lack of information regarding prognosis and efficacy of antineoplastic treatments in these species...

3-nitropropionic acid (3-NPA) is a nitrogenated compound produced by plants and fungi and has been associated with poisoning episodes in humans, animals, and to induction of Huntington disease symptoms in rats. The production of 3-NPA by endophytes has been reported, but the function and biosynthesis are not well-defined. The specie of endophytic strain G-01 was confirmed as Diaporthe citri using a multilocus sequence analysis, and was verified different concentrations of 3-NPA produced at different initial pHs by these strain...
