Indigestible neutral detergent fibers (iNDF) accurately predict forage digestibility when measured in situ. The objective of this study was to determine the effects of rumen incubation times on the estimated concentrations of iNDF for four forages (alfalfa hay, corn silage, wheat straw and orchard grass), four concentrates (barley grain, soybean meal, beet pulp and wheat bran) and two ...

Milk yield and quality were observed on 93 Angus, Brahman, and reciprocal-cross cows over 3 yr to evaluate the interactions of direct and maternal breed effects and heterosis with forage environment. Forage environments were common bermudagrass (BG), endophyte-infected tall fescue (E+), and a rotational system (ROT) of both forages, in which each forage (BG or E+) was grazed during its appropri...

Integrating livestock into cropping systems may enhance ecosystem services while still providing efficient food production. Including tanniferous forages in crop-livestock could further services. Interest phytochemicals, such as tannins, has increased over the past several decades, and research continues to reveal potential benefits of tannins agricultural systems. However, evaluating influence...

Introduction Among the different factors accounting for the better utilization of poor forages by goats, compared with sheep, urea recycling and better mastication during ingestion have been reported (Masson et al, 1986; Morand-Fehr et al, 1987). Our purpose was to measure the particle size in the alimentary bolus and to indirectly assess urea recycling, by chemical analysis of alimentary bolus.

s Equine motor neuron disease (EMND) is associated with and likely caused by prolonged vitamin E deficiency. Horses without access to at least seasonal pasture and fed forages and concentrates with low concentrations of vitamin E are at risk of developing EMND. At risk horses should be orally supplemented with additional vitamin E.

Stressful growing conditions often result in high concentrations of nitrates in plant tissue. When feeding animal forages containing toxic levels of nitrates, poor productivity or death may occur. This publication summarizes the effect that high nitrates have on the animal, presents the conditions to expect in toxic concentrations of nitrates, and outlines strategies that could prevent or reduc...

Forages can provide a complete diet for ruminant animals, increasing the sustainability of beef production systems worldwide while reducing competition with humans agricultural land or grain crops. Much emphasis on nutritional characteristics forages has been fiber, sugars, starch, and protein they supply to rumen, despite fact that other less-explored constituents, i.e., neutral detergent solu...

Seasonal changes in the climate, as well plants and species living this environment, which causes serious problems. Current work was carried out to evaluate seasonal impact on concentration of iron (Fe) zinc (Zn) soil, forages animals. A semi arid dry climatic area Pakistan selected find effects soil availability Zn Fe, its translocation Twenty seven were collected 320 ruminant samples from two...

The Mediterranean region is one of the areas most affected by climate change, which influences production forages. This has led producers to change from several forage cuttings, aiming maintain crop productivity in increasingly water-scarce conditions. study aimed evaluate nutrient content and produced for horses when subjected variable water availability conditions at a Lusitano stud farm loca...
