Transcripts
Slide 1

Reaping Forage Dr. Dan Undersander University of Wisconsin

Slide 2

Topics Quality misfortune with propelling development Wide swath framework Cost of fiery remains in scavenge Wheel activity on horse feed

Slide 3

Alfalfa Quality Loss with Advancing Maturity

Slide 4

Days without downpour at La Crosse

Slide 5

Wide swath advantages Faster drying Higher rummage quality

Slide 6

Sequence of Drying Forages Phase I dampness moves along stem Primary dampness misfortune is through stomata Phase II Primary dampness misfortune from the stem surface Phase III Removes firmly held water underneath 45%

Slide 7

Sequence of Drying Forages 80% Stomatal openings 70% Conditioning Moisture Weather managed Osmotic & Cell strengths 20% Time

Slide 8

Legumes 10X more stomata than Grass

Slide 9

Stomata Openings Sunlight – more they get the more they stay open Shading closes Stomata 20 – 30% of water expelled before stomata close Removes 30% of the water from the stem (grass)

Slide 10

Respiration proceeds in the wake of cutting until lose some water Breakdown of starch and sugars Carbon dioxide 2 – 8% of Dry Matter misfortune

Slide 12

Relative moistness inside windrow

Slide 13

Wide swath

Slide 15

Mower-conditioner Swath Width Study (Windrow 33% and Swath 65% of Cutting Width)

Slide 16

Alfalfa Moisture Content following 6 Hours Conditioned? Herzmann, 2004, Univ of Wisconsin

Slide 17

Alfalfa Moisture Content following 6 Hours Conditioned expanded drying rate Wide swath expanded drying more Conditioned? Herzmann, 2004, Univ of Wisconsin

Slide 18

Maximum swath width versus cutting width Maximum Swath Width Cutting Width

Slide 19

Moisture substance of horse feed 5.5 hours subsequent to slicing with different windrow width to cut width proportions, WI Farm Technology Days, 2002

Slide 20

Put feed into wide swath Keep off of ground

Slide 21

Mower Conditioner Options Sickle Cutterbar - move conditioner Disk Cutterbar - move conditioner Disk Cutterbar - impeller conditioner

Slide 22

Cross Section of Crop Stem

Slide 23

Conditioned roughage

Slide 24

Conditioner sorts Flail/impellers Rubber Rolls

Slide 25

Rollers versus thrash (impeller) conditioners

Slide 26

Roll and Impeller Comparison Roll makes a devastating activity Impeller makes a stripping activity Impeller has a tendency to have higher misfortunes Roll with rotating trimmer will leave strips in light crops (Limited air through back of machine)

Slide 27

Drying Rate Comparisons Cutterbar Conditioner Drying Rate Rotary Roll 0 Sickle Roll +.2 hr Rotary Impeller +1.8 hr

Slide 28

Conditioner drying rates Alfalfa Grass

Slide 29

Comparison of Losses(%) Wisconsin Study

Slide 30

Conditioner field misfortunes Flail conditioners have 2 to 3 % higher field misfortunes with hay. The misfortune is all leaves so scavenge quality is fundamentally decreased. Stems Leaves

Slide 31

Adjust conditioner legitimately Tension on rollers Spacing of rollers

Slide 32

Adjust conditioner roller dispersing Measure freedom where "Pleat" or littlest leeway happens

Slide 34

What is fiery remains? In scrounges, 2 sources. Inward sources (e.g. minerals like calcium, magnesium, potassium, phosphorous). Outer sources (e.g. earth, sand, bedding).

Slide 35

Why ought to % cinder be a worry? Powder gives minerals to the eating regimen, yet no calories (i.e. vitality). Assumes the position of supplements on right around a 1:1 premise.

Slide 36

What about exploration taking a gander at the impact of % fiery remains in the search in milk creation? "While there have been few dairy research trials here, it is profoundly likely that cows don\'t drain well when nourished soil." Pat Hoffman, Dairy Scientist, Marshfield ARS, 2002

Slide 37

What levels of powder would it be advisable for you to expect in a scavenge test?

Slide 38

Ash Content of Forage Samples Raking expands fiery remains substance of rummage

Slide 39

Lodged Alfalfa Possible Causes of Higher Levels of Ash in Forages

Slide 40

Possible Causes of Higher Levels of Ash in Forages Disk Cutterbar Cutting tallness

Slide 41

Wheel Rakes

Slide 42

Mower blade sort Those blades that "get feed" better, likewise get more slag

Slide 43

Percent Ash in First Cutting Growth of Alfalfa Hoffman and Others, Marshfield Agricultural Research Station, 1991

Slide 44

Rake legitimately

Slide 45

What would you be able to do? Cut feed onto layer of stubble Keep roughage off ground Wide swath Set rake not touch soil Merge instead of rake

Slide 46

Typical Forage Harvesting Losses Field curing - 26% 29% Fed 71% Lost Harvesting - 14% Storage - 35% Feeding - 30%

Slide 47

Optimum Management Field curing - 12% 71% Fed 29% Lost Harvesting - 8% Storage - 5% Feeding - 8%

Slide 48

Reducing the expense of a huge amount of scavenge If rummage costs $50/ton to create Cost of bolstered scrounge is $172/ton Cost of nourished search is $70/ton
