Performance and production of growing cattle (Bos taurus) on Coastal Bermudagrass [Cynodon dactylon (L.) Pers.] pasture are affected by forage allowance, but possible interactions with fertilizer nutrient source (i.e., inorganic vs. organic) and time have not been well described. We evaluated the effects of 3 nutrient sources with equivalent N rates: 1) inorganic, 2) crimson clover (Trifolium i...

Brangus cows (n = 29) were used in three experiments to evaluate the effects of parity (multiparous vs. primiparous) and potential genetic merit for milk production (high vs. low) on forage intake during late gestation, early lactation, and late lactation. Cows were selected for milk production based on their sire's EPD for milk production (MEPD). Cows had ad libitum access to (130% of previous...

Drought stress has an important role in yield reduction of crops. To investigate the effects of applying zeolite hydrogel (as a superabsorbent) in reduction of adverse effects of drought stress on chlorophyll content, nitrogen, growth indices and their relationships with quantitative and qualitative yield of pearl millet (cv. Nitrifeed), a split plot experiment (in space and time), based on ran...

One hundred thirty-eight Angus cross yearling steers (initial BW 390 ± 0.5 kg) were allotted by BW to a 3 × 2 factorial arrangement of 6 treatments (4 pens per treatment) to determine the effect of wet distillers grains (WDG) concentration (0, 20, 40% of dietary DM) in low-forage (12% hay) and high-forage (50% hay) diets on growth performance and marbling. Steers were implanted on d 0 with Comp...

This study was conducted to determine the important nutritional properties of pomegranate by-product (seed and peel) for evaluating its potential in silage preparation compared to corn forage. At first, enough fresh pomegranate by-products were prepared from a fruit juice factory in the fall season. Then, the chemical composition, fatty acid profiles, phenolic compounds and gas production param...
