Effects of dietary copper supplementation on nutrient digestibility, serum biochemical indices, and growth rate of young female mink (Neovison vison)
minks copper sulfate fat digestibility
2015/7/2
The objective of this study was to determine whether nutrient digestibility and growth performance of mink were affected by different dietary copper levels. Ninety-six 60-day-old healthy female minks ...
Uterine size in replacement gilts associated with age, body weight, growth rate, and reproductive status
pig reproduction puberty uterus
2015/7/2
The objective of the present study was to determine the association between the uterine size and age, body weight, growth rate, and reproductive status in Landrace × Yorkshire crossbred gilts. Genital...
Effect of triacylglycerols of medium-chain fatty acids on growth rate and mortality of rabbits weaned at 25 and 35 days of age
rabbits early weaning lipid supplements
2015/4/2
Three hundred Hyplus rabbits reared on a commercial farm were weaned at the age of 25 days and 300 rabbits were weaned at the age of 35 days. Early-weaned and conventionally weaned rabbits were assign...
Evaluation of physiological and health state of Norway spruce plants with different growth rate at juvenile stage after outplanting at mountain locations
health status mountain locality Norway spruce physiological trait
2015/3/27
Norway spruce (Picea abies [L.] Karst.) seedlings grown from seed originating from high mountain locations (8th forest altitudinal zone – Norway spruce vegetation zone 1,000–1,250 m a.s.l.) show highe...
Effect of age upon retention of mercury in chickens with a different growth rate
poultry deposition of mercury allometry of growth
2015/3/13
Retention of total mercury was examined in groups of 95 slowly-growing laying type chickens and 52 fast-growing broiler hybrids in 47 subsequent balance periods from 1 to 100 days of age. Chickens wer...
Increased cellular brevetoxins in the red tide dinoflagellate Karenia brevis under CO2 limitation of growth rate: Evolutionary implications and potential effects on bloom toxicity
Increased cellular brevetoxins Karenia brevis
2014/4/2
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico
via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
The Ewe’s Reproductive Performance, Growth Rate and Carcass Quality of Lambs Kept in a Barn vs Those Kept under an Overhead Shelter
Reproductive Performance Meat Quality Harsh Environment
2016/5/11
A herd of polish lowland local sheep was divided into two equal groups: the first group was kept under an overhead shelter, and the second group was kept in a warm barn. The effect of maintenance on e...
Growth rate of continental crust in the northeast margin of the North China Craton: Constraints from the U–Pb dating and Lu–Hf isotopes of detrital zircons from the Laoha River
North China Craton detrital zircon U–Pb age Hf isotope Laoha River
2017/4/11
Recently, how to quantitatively estimate the growth rate of continental crust is an enigmatic issue. With the development
of ICP-MS technology, the U–Pb dating and Lu–Hf isotopic compositions of detr...
Coral growth-rate insensitive Sr/Ca as a robust temperature recorder at the extreme latitudinal limits of Porites
skeletal oxygen isotope in the coral Sr/Ca high latitudes coral growth rates
2017/4/11
Oxygen isotope values of low-growth coral (<5 mm/yr) skeletons may reflect kinetic effects, which is problematic for
sea surface temperature (SST) reconstruction. Here, we report a Sr/Ca-based SST re...
