management of a companion crop is critical to successful establishment of perennial forages (Albrecht and Hall, Weed control during alfalfa (Medicago sativa L.) establishment is 1995). a primary concern of forage producers. Companion crops and clearWeed management is important for decreasing comseeding with an herbicide are commonly used methods for establishing alfalfa. This study evaluated an...

A novel method of harvesting whole-plant corn silage, shredlage, may increase kernel processing and physically effective fiber. Improved fiber effectiveness may be especially advantageous when feeding brown midrib (BMR) corn hybrids, which have reduced lignin content. The objective of this study was to determine the effect of feeding TMR containing BMR corn shredlage (SHRD) compared with BMR co...

The wilting process is required for the preparation of traditional low-moisture silage, which not only subject to interference rainfall during harvest season in many areas, but also increases labor, economic, and time costs. Therefore, this experiment, newly harvested alfalfa was supplemented with a complex additive consisting lactic acid bacteria (LAB), sucrose, corn flour, then ensiled direct...

19-33 ABSTRACT The objective of the research was to compare finishing beef steers on high corn (Zea mays L.) silage diets in which the corn was produced under conventional and sustainable systems. The conventional corn forage was produced on a given area for 5 yr, using conventional practices, alternating with 5 yr of alfalfa (Medicago sativa L.) The sustainable system corn forage was produced ...

The objectives of this study were to evaluate lauric acid (LA) as a practical ruminal protozoa-suppressing agent and assess effects of protozoal suppression on fermentation patterns and milk production in dairy cows. In a pilot study, 6 lactating Holstein cows fi tted with ruminal cannulae were used in a randomized complete-block design trial. Cows were fed a basal total mixed ration (TMR) cont...

The objectives of this study were to evaluate lauric acid (LA) as a practical ruminal protozoa-suppressing agent and assess effects of protozoal suppression on fermentation patterns and milk production in dairy cows. In a pilot study, 6 lactating Holstein cows fitted with ruminal cannulae were used in a randomized complete-block design trial. Cows were fed a basal total mixed ration (TMR) conta...

The in sacco protein and protein-free dry matter rumen degradability of three feeds, concentrate, alfalfa hay and maize silage, was determined simultaneously in three animal species: four Mediterranean buffalo (Bubalus bubalis) bulls, four Friesian bulls and four Delle Langhe rams, which received four diets differing in forage:concentrate ratio (1 5 87.5:12.5; 0.75 2 5 75.0:25.0; 3 5 62.5:37.5;...

The objective of this experiment was to determine the effects of feeding different levels of alkaline hydrogen peroxide-treated wheat straw (AHP-WS) in the diet on feed intake, nutrient digestion, ruminal fermentation, and production responses in mid-lactation dairy cows. Eight Holstein cows, averaging 147 d postpartum, were used in two replications of a 4 x 4 Latin square design. Complete mixe...
