Intermittent Saline Watering of Growing Beef Heifers

Studies on Feeding Wheat Middlings to Beef Heifers and Growing and Finishing Beef Steers

INTRODUCTION The type and amount of concentrate included in beef cattle diets can greatly influence production and profitability. Small grains are typically fed in these rations, but the inclusion of by-product feeds, such as wheat middlings (WM), in growing and finishing diets have recently been studied (Dalke et al., 1997; Blasi et al., 1998). Wheat middlings are the by-product of the wheat m...

Reproductive Management of Beef Heifers

Plasma nitrogen isotopic fractionation and feed efficiency in growing beef heifers.

Fractionation of N isotopes occurs in many metabolic reactions which causes tissue proteins to become enriched in ¹⁵N while urea (urine) is depleted in ¹⁵N relative to the diet. We investigated ¹⁵N enrichment of whole plasma and its relationship with feed conversion efficiency (FCE) in growing beef heifers (n 84) offered 2 kg/d of concentrates with grass silage ad libitum. Heifers were on avera...

Dose response to cinnamaldehyde supplementation in growing beef heifers: ruminal and intestinal digestion.

The objective of this study was to determine if cinnamaldehyde (CIN) could be used to improve feed intake, digestion, and immune status in growing beef heifers fed high-concentrate diets. The experiment was designed as a 4 x 4 Latin square using 4 ruminally and duodenally cannulated beef heifers with 4 treatments: control (no CIN added), 400 mg/d of CIN (low), 800 mg/d of CIN (medium), and 1,60...

Levels of Supplementation for Grazing Beef Heifers

The objective of this experiment was to evaluate the effect of providing different levels of a supplement on the nutritional characteristics and productive performance of heifers on pasture during the rainy-dry transition and dry season in Brazil or tropical area. Thirty crossbred heifers with predominance of Zebu breed were used in a completely randomized experimental design. Treatments consis...
