Wide swath advantages Faster drying Higher rummage qualitySlide 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% TimeSlide 8
Legumes 10X more stomata than GrassSlide 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 misfortuneSlide 12

Rollers versus thrash (impeller) conditionersSlide 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 hrSlide 28
Conditioner drying rates Alfalfa GrassSlide 29
Comparison of Losses(%) Wisconsin StudySlide 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 LeavesSlide 31
Adjust conditioner legitimately Tension on rollers Spacing of rollersSlide 32
Adjust conditioner roller dispersing Measure freedom where "Pleat" or littlest leeway happensSlide 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, 2002Slide 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 rummageSlide 39
Lodged Alfalfa Possible Causes of Higher Levels of Ash in ForagesSlide 40
Possible Causes of Higher Levels of Ash in Forages Disk Cutterbar Cutting tallnessSlide 41
Wheel RakesSlide 42
Mower blade sort Those blades that "get feed" better, likewise get more slagSlide 43
Percent Ash in First Cutting Growth of Alfalfa Hoffman and Others, Marshfield Agricultural Research Station, 1991Slide 44
Rake legitimatelySlide 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 rakeSlide 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
