It’s a labor of love to ensure the healthy delivery of cute, cuddly puppies. They don’t “just happen.” Several factors play into successful?dog reproduction?and dog breeding programs, including knowledge about basic reproduction, reproductive health for dogs, whelping and post-natal care.? At BioZyme®, our team adores dogs of all breeds, colors and sizes. We realize ...
The DNA sequence of a gene responsible for resistance to a devastating virus in wheat has been discovered, providing important clues for managing more resistant crops and maintaining a healthy food supply. Wheat crops in the Americas, Asia, Europe, and Africa are regularly damaged by wheat yellow mosaic virus (WYMV), and there is a high demand for wheat varieties or cultivars that are resistant ...
Not everyone will agree with my arguments in this article. However, I’m tired of hearing complaints about current sow mortality rates and general agreement that additional research is needed in gilt development; yet remain disappointed in the lack of tangible, practical strategies that producers can take home and implement at the ‘slat level’ to make meaningful changes in their ...
When people decide to raise chickens, a common question is which breed will be the best to choose for laying eggs. This decision is based upon innumerable factors and this post could not possibly cover them all, but we will go over several of them. By the way, the poultry egg incubator can hatchery chicken egg. First, of course, is overall egg production numbers. Different breeds of chicken ...
The main innovation components are to: use selective breeding to increase harvesting yield, and apply ground-breaking direct seeding on specially designed substrates to save time, energy and money in the hatchery phase. ...
The approach included use of genomic selection, the concept of using genome-wide dense genetic maps to predict the genetic merit of individual animals, and enhance selective breeding efficiency. ...
One day in the future, the Pacific Ocean could be home to kilometers of seaweed farms tended by submarine drones and waiting to be turned into fuel. This is the vision of Marine BioEnergy, a start-up backed by the Advanced Research Projects Agency–Energy (ARPA-E). The U.S. government agency is funding the company, along with a handful of related projects, because it views the open ocean as ...
Why Start a Fish Farming Business? Fish is a delicious and nutritious source of protein, rich in nutrients such as omega-3 fatty acids, which improve our heart health and lower blood cholesterol. Farmed fish play an important role in meeting global protein needs. The rise of fish in the home today opens up many lucrative opportunities. Home-raised fish can easily be sold nearby or around ...
After decades of regulatory and legal challenges, AquaBounty aims to bring genetically engineered salmon to U.S. and Canadian markets next year. On a hill above the cold waters around Prince Edward Island, technicians painstakingly create fertilized Atlantic salmon eggs that include growth-enhancing DNA from two other fish species. The eggs will be shipped to ponds in the high rainforest of ...

Combining science with traditional knowledge, researchers turn to ancient rice as a source of climate resilience In May 2009, Cyclone Aila wreaked havoc in eastern India. Clocking in at speeds of over 120 kilometers per hour, Aila hit the Sundarbans, the largest continuous block of mangrove forest in the world, located in the Ganga-Brahmaputra tidal delta on the Bay of Bengal. The storm killed ...

A locally owned, alternative model of supplying affordable seed is working for Africa’s framers, says Joe DeVries. Smallholder farmers in Africa — mostly women — wage silent battles against the elements and other forces beyond their control to feed their families, their villages, their countries. They have historically taken the lead in feeding Africa and are destined to ...
The use of maize (Zea mays L.) stover as a feedstock for cellulosic biofuels production will create demand for maize hybrids with greater stover yield. It is expected that grain yield will remain the most critical trait and continue to drive hybrid sales, requiring that any increases in stover yield be made without sacrificing grain yield potential. The objective of this review was to determine ...
Yield testing finished inbreds to replace preliminary single-cross corn (Zea mays L.) yield tests will increase rate of commercial hybrid yield gains. Studies have shown that heterosis decreased 25%/50 yr, 10%/60 yr, and 35%/100 yr. Natural selection and artificial selection by plant breeders for adaptedness have increased parental inbred and hybrid seed yields, whereas percentage heterosis ...
Despite widespread use of early generation testing and selection (EGT) in breeding for self-pollinated crops, its effectiveness remains largely an unresolved issue. This issue is tackled here using elaborated genetic models that enable genetic and nongenetic effects to be assessed for the effectiveness of EGT in terms of (i) the selection response at one or more early generations relative to the ...
Selection among breeding lines has been widely used to identify important cultivars and favorable alleles for adaptation, and resistance to abiotic and biotic stress. The objective of this work was to study the variability among common bean breeding lines selected from ancestral landraces, to evaluate the reaction of these lines to anthracnose (ANT) rust, common bacterial blight (CBB), halo ...
Little is currently known about the genetic variation within diverse gene pools of cultivated tobacco (Nicotiana tabacum L.). Knowledge in this area could aid in future germplasm maintenance activities, provide additional information in the area of N. tabacum population genetics, and assist in selection of materials for breeding or genetic investigations. To this end, 702 N. tabacum accessions ...
Knowledge of target environments in breeding programs is important to better direct the development of germplasm. The objectives of this study were to identify associations among barley (Hordeum vulgare L.) growing environments to identify mega-environments to select the best locations to breed barley. Twenty-seven years of grain yield data from the International Barley Yield Trial (IBYT) ...
The content of salicylic glycosides in the bark is differential and depends on genotype, therefore continued selection is necessary to find high-yielding crop varieties of S. purpurea with a high salicylic glycoside content of the bark. ...
Soybean [Glycine max (L.) Merr.] produces 29.4% of the world's edible vegetable oil. An important determinant of the nutritional value and the oxidative stability of soybean oil is the oleic acid content. Elevation of the oleate content levels leads to the improvement of soybean oil quality. However, our knowledge of the genetic factors underlying oleate variation in soybean seeds remains ...
A high-oil maize (Zea mays L.) (HOM) population, KYHO, was developed across 10 generations by selective breeding. The objectives of this investigation were to evaluate the effects of selection for kernel oil on correlated traits and measure the genetic variance of kernel oil content (KOC). Kernel oil content, kernel protein content (KPC), and kernel starch content (KSC) were estimated by ...
