Grass tetany, a Mg deficiency in ruminants, is responsible for large economic losses throughout temperate regions. Significant livestock losses occur in the semiarid western United States primarily when l...
متن کاملSupplementary Feeding of Grazing Beef Cattle
Some 60% of Australia% beef cattle are located in the tropics and subtropics, grazing, in general native pastures of low digestibility and N content. Production per head is low, as also are reproductive rates. The nutritional problem centres around the low contents of phosphorus, sulphur and nitrogen in pastures from June to December. This paper discusses responses in breeding cattle to supplem...
متن کاملTrace Mineral Supplementation of Grazing Beef Cattle
The nutrient quality of forage, particularly perennial warm-season grasses, is often lacking in trace mineral content to supply the requirements of most all classes of grazing cattle. Since forage is the most significant contributor to the trace mineral nutrition of grazing beef cattle, it is important to consider these deficits and how they may impact the performance of the cattle consuming th...
متن کاملDiversification of the P genome among Agropyron Gaertn. (Poaceae) species detected by FISH
The genomes of five Agropyron Gaertner, 1770 species were characterized using all potential di- or trinucleotide simple sequence repeat (SSR) motifs and four satellite DNA repeats as fluorescence in situ hybridization (FISH) probes. The sites of 5S and 45S rDNA were relatively conserved among the diploid and tetraploid species. A number of sites for the dinucleotide SSRs AC, AG, and pSc119.2 wa...
متن کاملBeef cattle losses after grazing Lupinus argenteus (silvery lupine).
Ten yearling steers weighing 270-360 kg died acutely after eating early seed pod stage Lupinus argenteus (silvery lupine) containing high levels of piperidine alkaloids, including ammodendrine and N-methylammodendrine. Reduced availability of Quality feed from range moderately depleted of Quality grasses appeared a major factor in causing the cattle to graze lupine. Proximate analysis of whole ...
