This study was carried out to compare in situ and in vitro enzyme techniques for determining estimates of forage escape proteins. Eight forages (vetch hay, wheat silage, corn silage, wheat hay, grass hay, lentil straw, triticale hay and alfalfa hay) were used as feed materials. During 70 h, incubation with enzyme method had similar escape protein values for vetch hay, wheat hay, grass hay, trit...

Nutritional disorders associated with both forage and feed consump­ tion can have a large impact on the profitability of beef cattle operations. Forages are an important component of beef cattle production systems in Arkansas. Most cow­calf and stocker cattle enterprises in Arkansas rely heavily on forage­based nutritional programs. Forages are used for both livestock grazing and hay production...

R7 stage (one seed pod at mature color; 50% of leaves yellow) produced forage that was similar in quality to Tall forage soybean [Glycine max (L.) Merr.] cultivars in maturity alfalfa harvested at early bloom. When soybean was groups V, VI, and VII have been developed to supply forage. Our objective was to determine the effect of harvest date and row spacing grown as an intercrop with corn, the...

The objective of this study was to evaluate self-fed byproducts on pasture reared finishing cattle. Major effects studied were animal performance, carcass traits and fatty acid (FA) profile with specific emphasis on conjugated linoleic acid (cis-9, trans-11–18:2; CLA). Eighty-two crossbred yearling steers were utilized in a 2 × 2 factorial design with implanted and non-implanted cattle fed eith...

We aimed to test the associative effects among forages, and between forage concentrates on in vitro digestibility of dry matter neutral detergent fibre using an artificial ruminal fermentation system. The study consisted two assays, which were evaluated three sugarcane, maize silage, Tifton 85 hay under incubation conditions (single feed or all feeds together a jar), sugarcane soybean meal and/...

Pastures located on southern Iowa cow/calf farms, from 8 to 125 ha in size, were used to evaluate the effects of microclimate, shade, botanical composition, and other pasture characteristics influencing the temporal/ spatial distribution of cattle within and outside streamside zones of pastures. Cows were Angus and Angus-cross on 4 of the farms, and Mexican Corriente on the remaining farm. Duri...

One of the most common problems faced by hay or silage producers is how to manage production schedules around unfavorable weather. Inevitably, some wilting forage crops are damaged by rainfall each year, and producers often inquire about the effects of rain damage, and what impact this may have on forage quality, silage fermentation, and animal performance. Actually, the problem is more complex...

This study aimed to investigate cyclopropane fatty acids (CPFAs) as quality biomarkers of forage feedings in cheese fat obtained from ewe’s milk, based on two different dietary treatments (hay and silage). The gas chromatography–mass spectrometry (GC–MS) analysis detected CPFAs most samples, both hay silage-based diets. CPFA levels feeding were positively correlated the total trans-monounsatura...

Paper mulberry (PM) and (MU) have been considered potential substitutes for traditional forages in response to the increasing demand high-protein feed livestock. To improve utility of these two typical woody forages, our study investigated effects sucrose lactic acid bacteria (LAB) additives on fermentation quality, nutritive value, protein fractions their leaf silages. Collected leaves were se...
