The nutritional composition and digestion of plants foraged by red deer(Cervus elaphus xanthopygus) in northeast China

We studied species of plants foraged by red deer in the Muling forest region of northeastern China during January 2014 and 2015. We focused on nutritional composition, energy content, and the digestibility of these plants. Crude protein content varied by plant species.Average crude protein content was 7.5 ± 1.7% of dry matter, ranging from 4.5 to 10.3%. Crude lipid content did not vary by species and averaged 7 ± 1.5%(range5.4–9.8%). Non-fiber carbohydrate(NFC) and neutral detergent fiber(NDF) content varied broadly with average values being 20.1 ± 4.8%(range 13.5–28.8%) and64.7 ± 5.9%(range 53.5–71.8%), respectively. Energy content ranged from 16.7 to 19.7 k J/g. Average dry matter digestibility(DMD) was 46.1 ± 4.8%, with a range from38.7 to 54.6%. Only three plants, Saussurea manshurica,Aralia elata and Equisetum hyemale exhibited DMD [ 50%. NFC content explained most of the variation in energy content(r = 0.451). In contrast, energy content was inversely related to NDF(r =-0.443). There was no correlation between crude protein, crude lipid, and energy content(r= 0.004, r=-0.190). S. manshurica,A. elata and E. hyemale had higher NFC and lower NDF content. Thus, these species offered the greatest nutritional value for wintering red deer in the study area. Along with high CP and NFC content, Taxus cuspidate also had high lignin content, and was thus, considered a good forage species for red deer.

Influence of dietary n-3 LC-PUFA on growth, nutritional composition and immune function in marine fish Sebastiscus marmoratus

Abstract A 60-day feeding experiment was conducted to investigate the influence of dietary omega-3 long-chain polyunsaturated fatty acids （n-3 LC-PUFA） on growth, nutritional composition and immune function of marine fish Sebastiscus marmoratus. Five diets containing 3.6, 10.2, 18.2, 26.5, or 37.0 g/kg n-3 LC-PUFA were prepared. The results reveal significant influences of dietary n-3 LC-PUFA on the final weight, weight gain, specific growth rate, feed conversion ratio, and condition factor. As dietary n-3 LC- PUFA increased, weight gain and specific growth rate increased and were significantly higher in groups fed 18.2, 26.5 and 37.0 g/kgthan in groups fed 3.6 and 10.2 g/kg （P〈0.05）; there was no significant difference between groups fed 18.2, 26.5, or 37.0 g/kg （P〉0.05）. With increasing dietary n-3 LC-PUFA, eicosapentaenoic acid and docosahexenoic acid content in muscle and liver increased significantly, immunoglobulin class M content gradually increased from 9.1 to 14.8 Ixg/L, and lysozyme activity content increased from 1 355 to 2 268 U/mL. Broken line model analysis according to weight gain indicated that a dietary n-3 LC-PUFA level of 18.2 g/kg is essential for normal growth at a fat level of 125 g/kg. Therefore, appropriate dietary n-3 LC-PUFA not only promote growth and improve the n-3 LC-PUFA content, but also enhance immune function in S. marmoratus.

Sensory Characteristics, Nutritional Composition, and Quality of Eggs from Different Chickens

The present study evaluated the sensory, composition, and quality of eggs from Cosmopolitan (C), Improved Horro (H), ♂ Improved Horro * Cosmopolitan ♀ (HC), ♂ Cosmopolitan * Improved Horro ♀ (CH), Indigenous(L), and Koekoek (KK) genotypes. A completely randomized design was used in the study. A total of 108 (18/genotype), 180 (30/genotype), and 90 (15/genotype) eggs were used for the sensory, composition, and egg quality tests, respectively. All data were analyzed following the GLM model using SAS software. The boiled and scrambled eggs from L, H, and C were (P ≤ 0.001) preferred followed by CH, HC, and KK. Results showed that KK, HC, CH, and C eggs were higher in moisture, crude fat, crude ash, and crude fiber, but these traits were found lower in H and L genotypes. A significantly highest crude protein was observed in L (21.19 ± 0.19) genotype, with higher in H (20.62 ± 0.26), intermediate in HC (19.96 ± 0.29), C (19.85 ± 0.10), and CH (19.40 ± 0.37), whereas the eggs from KK genotype had the lowest crude protein content (18.69 ± 0.20). The egg quality was (P = 0.001 - 0.01) affected across traits except for eggshell indices (P > 0.05). The genotypes with a negative significant correlation with crude protein had a positive significant correlation with almost all composition and egg external quality traits. The genotypes with positive significant correlations of egg weight had positive significant correlations with most internal egg quality traits except that of yolk weight ratio, yolk albumen ratio, and yolk color. Conclusively: the eggs of L, H, and C genotypes were best favored followed by CH and C, but the KK genotype was the least favored, and these differences were deemed due to genetic variations, and interventions. Furthermore, the eggs laid from genotypes with deep yellow yolk color might be the most nutritious. It could also necessitate future breeding and dietary studies.

Physical Characteristics and the Effect of Boiling and Fermentation on the Nutritional Value of <i>Telfairia occidentalis</i>Seeds

This work evaluates some physical parameters (the weight, length, diameter of fruits and seeds, number of seeds per fruit) and the effect of boiling and fermentation on the nutritional value of Telfairia occidentalis (fluted pumpkin) seeds. Firstly, a survey was done in the city of Yaounde on the different treatments applied to the seeds before cooking. From the results of the survey, the seeds were divided into three groups: raw, boiled and fermented. The moisture, lipid, protein, fibre, carbohydrate and ash contents were analysed using AOAC methods and minerals by atomic absorption spectrophotometry. The results showed that T. occidentalis fruit averagely weighed 6.35 kg and contained about 90 seeds. The decorticated seeds had an ovoid shape, 3.70 cm long and weighed 8.91 g. Boiling led to an increase in lipid (16.29% - 31.44%) and carbohydrate (19.20% - 21.8%) but a decrease in protein (54.06% - 34.17%) contents. Fermentation increased the crude fibre (0.70% - 1.1%) but decreased the ash content (4.07% - 3.14% DM). Boiled seeds had higher calcium, magnesium, potassium and sodium, while fermented seeds had higher zinc levels. Boiling proved better in preserving most of the seed nutrients. These seeds could be used to prevent some mineral deficiencies and their high proteins suggest their potential for the formulation of infant foods.

Availability, Accessibility and Contribution of Infant Flours to the Diet of Children Aged 6-59 Months in Benin

This study assesses the nutritional composition as well as the availability and affordability of infant flour found on the market and in the households of Benin. To do that assessment, a two-step cross-sectional survey based on food ethnography methods was used. A total of 61 marketplaces were visited in seven towns and rural districts as part of the availability and affordability survey, while 400 children (aged 6 to 59 months) were surveyed to track the uses of infant flours at the household level. The results obtained reveal that pre-manufactured infant flour is sold more in urban areas (Cotonou, Porto-Novo and Parakou) than in rural ones. The average infant flours price did not vary (p = 0.985) in any given year (regardless of abundance or lean periods) nor does it vary (p = 0.133) from one point of sale to another (drugstore or supermarkets). However, the average price is found to be expensive considering the purchasing power of the households surveyed. On the other hand, the amount of ingredients used in the production of the flour types found on the market complies with the recommendations of the Codex Alimentarius, unlike the homemade ones. Pre-manufactured infant flour is found to be outside of the economic reach of most households (92%) who rely heavily on the homemade ones to feed their children. In light of the above, public authorities should help improve geographic access and pricing affordability to quality infant flour for low-income households in urban and remote areas. Moreover, awareness should be raised among mothers relative to the importance of complementary feeding through education on good nutrition practices.

Light shading improves the yield and quality of seed in oil-seed peony(Paeonia ostii Feng Dan)

Tree peony seed is unique for its super-high content of unsaturated fatty acid and is thus considered as an important source of woody oil. However, photosynthetic production is greatly reduced under high light intensity and air temperature during the seed filling period, which negatively affects seed yield and quality. The objective of this study was to determine if appropriate shading improves yield and quality of seed in oilseed peony. In this study, oilseed peony trees were shaded by different density polyethylene nets from four weeks after flowering to harvest stages to form light, moderate, and severe shadings, equivalent to about 80, 40, and 20% of full solar exposure, respectively. The effects of different shadings on some physiological parameters, yield and yield components, and nutritional composition of seed were examined. Averaged across two years, light shading increased the actual net photosynthetic rate（P_n） by 16.8%, the maximum net photosynthetic rate（P_（max）） by 81.4%, chlorophyll（Chl） content by 52.8%, auxin（IAA） content by 38.1%, and gibberellic acid（GA_3） content in leaves by 6.3%; it decreased the accumulation of H_2O_2 in leaves by 24.8%, malondialdehyde（MDA） by 22%, and endogenous abscisic acid（ABA） by 8.8%, indicating that leaf senescence in late season was considerably delayed. Light shading increased seed yield, and contents of crude fat and unsaturated fatty acids by 9.7, 5.6, and 9.6%, respectively, while moderate or severe shading significantly reduced all the three parameters. Light shading increased seed weight, but moderate or severe shading reduced seed weight or follicle density. The improved seed yield under light shading was mainly due to increased seed weight, while the reduced seed yield under moderate or severe shading was mainly attributed to reduce follicle density and seed weight. The improved seed weight and content of unsaturated fatty acids under light shading was possibly due to the delayed leaf senescence. The overall results indicated that light shading is beneficial to yield and quality parameters of seed in oilseed peony. Cultivating oilseed peony under a light shading environments such as partially closed forests would better increase total output and income per unit land area than that under full solar exposure.
