Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Soybean (Glycine max) seed yield and quality are strongly affected by drought, particularly during reproductive stages. We evaluated 22 genotypes under irrigated and rainfed conditions across three Missouri environments (2023–2024) for seed yield, 100 seed weight, protein, oil, and five fatty acids. Mixed models were used to partition genotype,

Deletion of Astrocytic TNFR1 Attenuates Hyperexcitability and Initiation of Epileptogenesis
Glia, Volume 74, Issue 9, September 2026.Inducible, astrocyte‐specific deletion of TNFR1 reduces basal EEG spectral power. Loss of astrocytic TNFR1 attenuates acute seizure activity in two distinct experimental models of epilepsy. Deletion of TNFR1 in astrocytes limits epilepsy development and hippocampal pathology in a mouse model of temporal lobe epilepsy with hippocampal sclerosis ...

Effects of Method of Mating on Fertility in Broiler Breeder Hens
Poultry Science, 1976 Sexually mature commercial broiler breeder pullets were housed singly in laying cages or in floor pens and mated by means of artificial insemination alone, natural mating and natural mating supplemented by artificial insemination. The best fertility, was obtained by the combination method where natural mating was supplemented with artificial ...

Iodine Toxicity in Large White Turkey Breeder Hens
Poultry Science, 1991 Iodine was fed to turkey breeder hens during a 20-wk laying cycle to determine the appropriate dietary level to support reproduction and avoid toxicity. A basal diet that contained by analysis. 7 ppm iodine supported good hatchability of Large White turkey eggs. Supplementing 35 or 350 ppm iodine to the basal diet resulted in toxic effects (P less than

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.This study reported the effect of Mito‐TEMPO on rooster semen quality cryopreserved in Beltsville extender. Semen diluted in extenders containing 10 or 100 µM of Mito‐TEMPO presented higher motility, average path velocity as well as membrane/acrosome integrity, mitochondrial activity, and fertility rate; and lower lipid peroxidation, apoptosis rate ...

Performance of Broiler Breeder Hens on Wire and Litter Floors
Poultry Science, 1984 Two experiments were conducted with broiler breeder hens to study the influence of litter versus wire floor on weight and specific gravity of eggs. In Experiment 1, one group of broiler breeder hens was maintained on litter and the other on wire. Specific gravity was significantly higher for eggs from hens kept on litter floors.
