Muscle fiber characteristics had beneficial effects on meat masses and quality in broilers. Its number is determined at birth directly affects the growth development of muscle fibers after birth. However, whether different types chickens are has not been fully documented. In this study, 1-day-old Xueshan chicken (slow-growing broiler) Ross 308 broiler (fast-growing were selected, respectively, type distribution, density, size breast (pectoralis major, PM) leg (gastrocnemius, GAS) muscles...

The selection of broilers for augmented growth rate and breast yield has been accompanied by deterioration in meat quality. To characterise the quality differences between slow- (SG) fast-growing (FG), Xueshan Ross 308 chickens were employed to determine mechanisms causing these differences. SG was found display more redness yellowness, higher shear force, pH24h, protein content, with lower intramuscular fat (IMF) content than FG meat. Further, based on comparative phosphoproteomic analysis...

Spaghetti meat (SM) is a newly identified muscle abnormality that significantly affects modern broiler chickens, consequently exerting substantial economic impact on the poultry industry worldwide. However, investigations into quality and underlying causative factors of SM in broilers remain limited. Therefore, this study was undertaken to systematically evaluate fiber characteristics SM-affected meat. To elucidate disparities between normal (NO) muscles chickens reared under identical...

Abstract In this study, fast-growing poplar reclaimed from abandoned homestead in Xixian New District, Xi’an City, Shaanxi Province, was used as the research object to explore multi-fractal characteristics of soil particle size distribution under different management modes land (control), irrigation, fertilizer irrigation and mixed irrigation. The results showed that mean values clay, silt sand were 14.58%, 81.21% 4.22% respectively, 14.08%, 79.92% 5.99% 15.17%, 81.19% 3.64% 16.75%, 80.20%...

Geese are extremely well-adapted to utilizing plant-derived roughage in their diet, so the grass must be added commercial diets under intensive rearing systems. However, it is unclear whether gut microbiota will change significantly when adding different proportions of ryegrass. In this study, 240 healthy male Yangzhou geese (28 days old) with similar body weights were randomly divided into four groups and fed (CK, whole diets; EG1, ryegrass: = 1.5:1; EG2, 2:1; EG3, 3:1) respectively. When...

The quality (color, tenderness, juiciness, protein content, and fat content) of poultry meat is closely linked to age, with older birds typically exhibiting increased intramuscular (IMF) deposition. However, specific lipid metabolic pathways involved in IMF deposition remain unknown. To elucidate the mechanisms underlying changes, we conducted a study using geese at 2 distinct growth stages (70 300 d). Our findings regarding approximate composition revealed that as aged d, their acquired...

The volatile aroma compounds in raw duck meat strongly affect consumers’ purchase decisions and they vary among breeds with different growth rates. In this study, slow-growing (SG) Liancheng White fast-growing (FG) Cherry Valley ducks were selected, their characterized using electric nose gas chromatography-mass spectrometry. Furthermore, a widely targeted metabolomics approach was used to investigate the metabolites associated compounds. results showed that hexanal, nonanal, octanal,...

Marketable age is an important determinant of meat quality. Cherry Valley duck (SM3 medium) the most efficient Pekin-type and widely farmed breed globally. However, whether marketable determines quality ducks not well documented. The objective this study was to investigate effect on proximate composition nutritional profile breast from broiler ducks. Ducks at 28, 38, 42, 45 days old were selected slaughtered, their composition, cholesterol essential mineral compositions, amino acids fatty...

Urbanization causes increases in temperature and alters soil carbon (C), nitrogen (N), phosphorus (P) cycles, but the degree to which these processes vary sensitivity along urban-rural gradient are unclear. We selected three typical vegetation types (forests, shrub, lawn) an urban-subruban-rural Nanchang, China, collected topsoil (at 0–15 cm depth) from 27 plots each measure C, N, P mineralization rates using thermostatic incubation. This was performed at ambient temperatures of 5 °C, 15 25...

This study was conducted to determine the effects of diet with different proportions ryegrass on breast meat quality geese. In total, 240 healthy male Yangzhou geese (28-day-old) similar body weight were divided randomly into 4 groups (control group: fed commercial diets; treatment I, II, and III: in ratios 1.5:1, 2:1, 3:1, respectively), birds being from age 29 70 D. The results shows that weights 70-day-old II III lower than those control group, whereas group I group. contents flavor amino...

Nitrogen is the primary nutrient limiting ecosystem productivity over most of US. Although soil nitrogen content important, knowledge about its spatial extent at continental scale limited. The objective this study was to estimate net mineralization for conterminous US (CONUS) using an empirical modeling approach by scaling up site level measurements. Net and total data across CONUS were obtained from three different ecosystems: low elevation forests, high grasslands. Equations predict...

Mating behavior is a critically important component of poultry reproduction. Here, total 135 geese were selected, specifically, Sichuan white (Anser cygnoides), Zhedong and Hungarian anser) (300-day-old), the mating was monitored daily from 6:00 a.m. to p.m. during 20-day observation period. The results showed that process included mounting, female cooperation, successful copulation. Overall, three breeds preferred on land. More than thirty percent time primarily concentrated 4:00 in...

Abstract Rice cultivation is the main method for mudflat reclamation. However, changes in community structure of microbes involved nitrogen (N) cycling response to reclamation via rice remain poorly understood. This study used quantitative polymerase chain reaction characterize distribution various inorganic N‐cycling pathways cultivation. The results show that abundance functional genes followed an increasing trend, while relative showed a decreasing trend. richness network different...

Forests, covering one-third of the global landmass, are world’s most vital terrestrial ecosystem [1]. [...]

There is an increasing understanding of the importance biochar-based fertilizers in agroecosystems. However, no research has evaluated effects partial substitution urea with on rice yields and soil microbial communities. We therefore investigated yields, bacterial communities, gene abundance involved nitrogen silty clay sandy loam paddy fields treated (U), total (BSU), basal tillering (BSU1), panicle (BSU2).Compared U, applying increased BSU2 having most notable effect. Principal coordinate...

Background: Dopamine β-hydroxylase (DBH) is a critical enzyme in the biosynthesis of catecholamines.This enzyme's role neuroendocrine regulation well known, but there are some indications that it may also modulate reproduction and endocrine mammals birds.We selected goose (Anas cygnoides) as an ideal model species for investigating DBH avian reproduction.Results: Full-length cDNA encoding was cloned from Zhedong using reverse transcription PCR rapid amplification ends.The consisted 126-base...
