📢 Featured Research of the Week 📢 Title: Can Early Environmental Enrichment Buffer Stress from Commercial Hatchery Processing in Laying Hens? Authors: Louise Hedlund, Enya Van Poucke and Per Jensen Key Finding: This study reveals that environmental enrichment in hatchery chicks may reduce stress sensitivity by altering their physiological response to stress. Although behavioral impacts were mixed, enrichment appeared to buffer physiological stress sensitivity in chicks exposed to hatchery stress. Why it Matters: Early-life stress is a critical factor in poultry welfare and productivity. This study suggests that enrichment could potentially help manage stress in hatchery-raised chicks, leading to healthier and more resilient flocks, even under commercial conditions. 📖 Read the full paper: https://lnkd.in/dbwhqB5B #PoultryResearch #AgriculturalScience #FoodSecurity

💡Lights out! And stop eating your little brother! 🐟 Despite their charismatic cuteness, lumpfish, valuable as “cleanerfish” to the lucrative salmon aquaculture industry, can be aggressive toward each other, presenting a challenge to raising them. But new research from UNH found that changing both the lighting and the density of lumpfish in hatchery tanks can reduce this feisty behavior (which includes cannibalism). The researchers found that when small lumpfish had 12 hours of light and 12 of darkness, instead of constant light, and when there were fewer of them in a tank, they reduced instances of aggressive tail fin nipping. “Understanding the factors that exacerbate lumpfish aggression, and providing guidelines for mitigating this behavior to aquaculturists, are essential for increasing hatchery production and rearing efficiency,” says research associate professor Elizabeth Fairchild, who published this research in the North American Journal of Aquaculture with Brittany Jellison, assistant professor of biological sciences, and master’s student Shelby Perry.

Differences Between Natural Mating and Artificial Insemination https://lnkd.in/d6J5BpHU

Kichawi Kill, is among the few mycoherbicides that have been successfully commercialized in the world, with application success in Africa for fighting Striga hermonthica. This perspective by Dr. Steve Duke describes the challenges - and opportunities with technologies like ours. We point to this paper as a recent analysis of the weed management biocontrol industry. As you will see in the table, we are one of only a handful of successes so far. Our first target is Striga (kayongo), which is considered the worst pest threat to food security in Africa. https://lnkd.in/gW4qz79N

(Journal Review) Use Of Lures With A Mix Of Sweet And Fetid Odors For Catching Musca domestica L. In Domestic Environments INTRODUCTION The housefly [Musca domestica L. (Diptera: Muscidae)] is a well-known insect pest closely associated with human activities in urban and rural environments (Malik et al. 2007). The occurrence of this insect in domestic environments originates from hygiene failures and increases the potential for transmission of fecal–oral pathogens (Colacci et al. 2020) of numerous diseases including dysentery, typhus fever and cholera (Fotedar et al. 1992; Junqueira et al. 2017; Bahrndorff et al. 2017; Khamesipour et al. 2018). Musca domestica is usually controlled by application of chemical insecticides, leading to negative drawbacks including development of resistance (Walsh et al. 2001; Kaufman et al. 2010) and environmental contamination, the latter being particularly undesirable in the domestic environment. In this context, a crucial constituent of a successful housefly management program is the use of traps for catching M. domestica adults (Gerry 2020). The using of traps, baited with an attractant effective and suitable, is a tool of key importance for achieving optimal results in monitoring/ controlling houseflies (Upakut et al. 2017). Since the life cycle of M. domestica is strictly related to animal carcasses, feces and other substrates in decomposition, this insect is generally attracted to unpleasant odors. The possibility of using chemicals with these odors for trapping houseflies is limited by the “fetid” nature of these compounds (Cossè and Baker 1996; Zito et al. 2014) strongly undesired in domestic environments and other urban contexts.

Family x environment interactions exist in farmed salmon. We recently found pre-harvest maturation is one trait that is not consistent between the same families reared under different smolt environments (left panel below). We also see male maturation in land-based "large-smolts" really kicks off once fish go over 250g when kept on steady 13°C and continuous light from first feeding (the right panel in the graph below). You can reduce this by using fish that are homozygous for the late maturing vgll3 allele (LL in the figure, compared to homozygous early (EE) or heterozygous fish (EL)).

#FarmerFocus - In partnership with USDA-NRCS and The National Association of Conservation Districts, the Soil Health Institute interviewed 30 farmers in 20 states who have implemented a soil health management system (SHMS) to examine the economic and on-farm benefits they experienced. The Tim Cornie farm in the Upper Snake-Rock Watershed of Idaho increased profitability by $15.91/acre through revenue derived from grazing cattle with a SHMS of planting cover crops. Additional benefits included improved soil biology and structure, increased water infiltration, decreased erosion, and reduced pest pressure.
