Tre6P (trehalose-6-phosphate) mediates sensing of carbon availability to maintain sugar homeostasis in plants, which underpins crop yield and resilience. However, how Tre6P responds to fluctuations in...
How do we increase food production by more than 50%, on a limited amount of arable land, to feed a projected 10 billion people by 2050?
The rate at which humans consume fresh water is now approaching or surpassing the rate at which water sources are naturally replenished, creating shortages for people and ecosystems.In the western U.S...
Galaxies grow by accumulating gas from their surroundings and converting it to stars, but the details of this process have remained murky. New observations, made using the Keck Cosmic Web Imager at th...
Facility Management activities require to collect and organize a large amount of information about a building as, for example, geometry, MEP structures, lighting and antifire devices, typologies of fu...
The objective of this study was to calculate economic weights for ten current breeding objective traits and for four new traits characterising claw health and feed efficiency in Czech Holstein cattle ...
The effect of glutamine and/or probiotic (Enterococcus feacium) supplements on piglet performance, intestines structure, and microbial status was estimated on 181 piglets (16 litters) of Polish Landr...
This study aimed to investigate the effects of single or/and double strains of probiotic supplement on feed efficiency, growth performance, and microbial population in distal gastrointestinal tract (G...
An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L.) on feed intake and utilization, and production performance of cr...
The feed intake (FI) and feed efficiency are economically important traits in ducks. To obtain insight into this economically important trait, we designed an experiment based on the residual feed inta...
Washington State University biologist Mechthild Tegeder has developed a way to dramatically increase the yield and quality of soybeans. Her greenhouse-grown soybean plants fix twice as much nitrogen ...
This study was conducted to determine the effect of lysozyme addition on in vitro rumen fermentation and to identify the lysozyme inclusion rate for abating methane (CH4) production. An in vitro rumin...
Estimation of feed intake (FI) for individual animals within a pen is needed in situations where more than one animal share a feeder during feeding trials. A partitioning method (PM) was previously pu...
The aim of this study was to evaluate the effect of replacing corn grain for sugar cane molasses (MO) or glucose syrup (GS) in the starter concentrate on performance and metabolism of dairy calves. Th...
The ban on dietary antibiotic growth promoters (AGP) in swine production has focused increasing research efforts on the development of alternative feed supplements. One such alternative to AGP is the ...
