Interseeding silage corn into an alfalfa stand following its spring harvests to produce mixed would feasibly break the restriction of production during a hot-rainy summer. In this 2-yr experiment, alfalfa–silage intercropping system (AC) with nitrogen (N) fertilization rates 0, 60, 120, and 180 kg N ha?1 plant densities 30,000, 45,000, 60,000 plants was compared monocultured (CK) managed using ...

. eight holstein cows in early lactating stage were used in a 4×4 change-over design within 4 periods of 21-d to determine the effects of alfalfa hay particle size and soybean oil supplementation on intake, digestibility, ruminal and blood metabolites, chewing activity, milk yield and compositions. four total mixed rations containing 20, 20 and 60% corn silage, alfalfa hay and concentrate respe...

We evaluated the effects of cellulase (from Trichoderma longibrachiatum) application rates on neutral detergent fiber (NDF) concentration and fermentation products of orchardgrass (Dactylis glomerata L.) and alfalfa (Medicago sativa L.) silages harvested with decreasing dry matter (DM) digestibility. Additionally, the impacts of inoculant (Lactobacillus plantarum and Pediococcus cerevisiae), pe...

The objective of the present experiment was to quantify the gas production parameters, methane emission and microbial nitrogen production of a conventional total mixed ration including corn silage, alfalfa hay, wheat straw and concentrate (390, 110, 22 and 478 g/kg of diet DM, respectively) treated with different levels of Natuzyme® and pre-incubation time after enzyme administration. Two hundr...

this study was conducted to evaluate consumption inputs, production costs, nutrient composition and performance in production of alfalfa hay and alfalfa silage. therefore, data on alfalfa hay production were collected from 75 farms in zanjan province, using a face to face questionnaire in the year 2012. a systematic random sampling method was used. then, two farms managed by silage harvesting s...

two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (pb) extract. pb was soaked in water with a ratio of 1:5 (w/v) for 12 h. after filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...

The Penn State Particle Separator has led to widespread measurement of forage and total mixed ration (TMR) particle size. However, a large proportion of small particles may pass through both sieves when a TMR is analyzed, and field research has suggested that both shaking frequency and sample dry matter may affect the results. The objectives of this project were to test the effects of an additi...

Three experiments were conducted to determine the effect of receiving diets containing alfalfa meal and certain feed additives on performance of comingled feeder pigs transported 900 to 1,100 km. In Exp. 1, the inclusion of 9.4% dehydrated alfalfa meal in receiving diets for 2 wk resulted in no difference (P greater than .1) in gain or feed conversion from purchase to market compared with pigs ...

Two experiments were carried out to determine the nutritive value and to evaluate the performance of growing rabbits fed on isoenergetic diets containing high moisture sorghum silage grain with low or high tannin levels. In the digestibility assay (experiment 1), the nutritive values of silages were determined with 30 New Zealand White rabbits, 15 males and 15 females, 55 days old, allotted in ...
