the objective of this study was to determine the effects of two different time of gnrh injection after artificial insemination (a.i) (d 6 and d 12) on reproductive performances of holstein cows during the warm season.  cows randomly assigned to treatments 1) no gnrh injection (control, n = 300),2) gnrh injection at day 6 after a.i (g6, n=300) and 3) gnrh injection at day 12 after a.i (g12, n=30...

Limited availability of herbage during the cool season creates a problem of a supply of nutrients for livestock producers throughout the southern Great Plains of the USA and, particularly, on small farms where resource constraints limit possible mitigating strategies. Six coolseason grasses were individually sown into clean-tilled ground, no-till drilled into stubble of Korean lespedeza [Kummer...

BACKGROUND Seasonal variation of flow-mediated vasodilation (FMD) remains controversial. A large cohort study showing that FMD was highest in summer and lowest in winter has been performed in a cross-sectional manner on different populations in different seasons, and the results for the same population were not compared. METHODS FMD was compared between the cool season (14.4 ± 4.4°C) and warm...

California is suffering from a serious drought and the future of turfgrass and other landscape plants has never been more uncertain. Use of drought tolerant plant species should be at the forefront of water conservation management plans for golf courses and other landscapes. Warm-season or C4 grasses are better adapted to warmer, drier climates and use at least 20% less water compared to cool-s...

Differences in nutrient content between different grass hay varieties are much smaller than differences between legumes and grasses (Table 1). Cool-season grasses (grown in temperate climates) include timothy, orchardgrass, fescue and annual ryegrass. Warm-season grasses (adapted to tropical and subtropical regions, like Florida) include Coastal bermudagrass, Tifton-85 bermudagrass, and bahiagr...
