    calving)????(????)

  • Sorting leaving some of the forage ??,?????
  • High intake animals??????
  • High degree of variability in ration and meal
    patterns?????
  • Poorly balanced diets???????

31
Dry diets can be easily be separated by
cows??????????????

34
Poor environments increase risk of SARA
?????????????????
  • Heat stress???
  • Overcrowding?????
  • Uncomfortable stalls?????
  • Why?????
  • Competition /aggressive behaviour????/?????
  • Alter feed intake patterns??????
  • Animal behaviour????

35
Strategies for reducing SARA?????????????
  • Increase diet digestible fibre content
    ???????????
  • Add Sugar Beet Pulp?????/???
  • non-forage fibre sources??????
  • fibre in SBF less filling than forage
    NDF?????????????NDF?
  • Smaller particle size???
  • digested more quickly???????
  • high in DIGESTIBLE fibre????????

36
Comparing NDF levels and digestibilityNDF????????
?
37
Starch levels can be reduced????????
38
Better forage quality?????
  • Cut younger green???-??
  • Higher in digestible fibre
  • ??????
  • Palatable????
  • Consistent throughout the clamp????
  • Chop length
  • ????
  • KNOW THE ANALYSIS??????

39
Increasing physically effective fibre increases
time being a cow!??????,?????????
40
Keep things balanced 1. the diet????-1.??
  • Balance digestible fibre and starch ??????????
  • Chop the forage 3 8 cm??????3-8cm
  • No wider than the cows mouth!??????????
  • Max 4 Kgs concentrate per feed??4????
  • Good mix????
  • Push up the feed to the barrier often??????
  • Add molasses to reduce sorting????????

41
Forage as wide as her mouth!?????????
42
Keep things balanced 2. the environment????-2.?
?
  • Feeding as often as possible ad
    libitum???????-???
  • Keep the feed fresh??????
  • Allow more space for cows to feed???????????
  • Less competition for feed????
  • Less aggressive behaviour???????
  • Avoid summer heat stress?????
  • Comfortable place to lie?????

43
Enough room to feed???????
44
Pectin reduces risk of SARA????????????
  • Pectin has low concentrations in most feeds (lt 2
    to 3) ??????????(lt2-3)
  • Some feeds contain higher concentrations such as
    sugar beet pulp (15 to 20)?????????????(15-20
    )
  • Pectin??
  • Highly fermentable?????
  • High whole tract digestibility ?????
  • Moderates rumen fermentation, unlike fermentation
    of starch, as rate of pectin fermentation slows
    as rumen pH decreases.???????????????????????PH??
    ??????????

45
Measures of good rumen activity?????????
  • Cudding frequency and rate???????
  • Post feeding gt60 should be cudding with
    vigour???gt60?????,????
  • Dung colour and texture???????
  • Dark khaki, firm not stiff, no foaming devoid of
    measurable amounts of fibre and
    grain????,?????,????????????????
  • Sieving under cold water should leave very fine
    fibre/hairy skeletons?????????????????/??
  • Bloom????
  • Degree of sheen on the coat????
  • Posture and activity?????
  • Head up and alert???,????

SBF stimulates development of calf rumen wall
??????????????
  • Replacing grain with SBF and other digestible
    fibre sources stimulates the physiological and
    metabolic development of the rumen
    wall???????????????????????????????????????
  • Increasing in dry matter intake
  • ????????
  • Allows smooth transition to non milk diets
  • ????????????
  • Repeatedly demonstrated on Chinese farms

SBP Products???
  • Raise rumen pH that is low due to
  • Feeding high acid forages especially lactic
    acid
  • ?????????????
  • Feeding high starch diets??????
  • Using high feed rates per feed and/or per day
  • Poor structural value leading to low cudding
    rates and saliva (natural buffer) production
  • ??????????????????(?????)
  • Can be used as part of a strategy to reduce the
    risk of Sub Acute Ruminal Acidosis (SARA) (acid
    stomach)
  • ??????????????????????
  • Contribute to minimising the risk of diet related
    laminitis (swelling of the hoof
  • ????????????

51
SBP Products summary ???????
  • Recommended feeding rate
  • ??????
  • 2 - 4 Kgs per cow per day ?????2-4??
  • Up to 20 of concentrate diet ???20
  • Safe to feed more ??????

52
SBF Products summary ???????
  • ?????????? High digestible fibre source
  • ????????,?????? Key element of a program to
    maintain rumen health
  • ?????????,???????????????????
  • Rich source of digestible fibre to promote milk
    yield and fat for cow and sheep
  • ?????????? Contributes to reducing lameness
  • ????????,???????? Can fed to swine, especially
    pregnant sows
  • ?????????????,????????.?????????????????? Pressed
    pulp provides valuable rumen structure to open
    the ration and provide a cost effective
    alternative to forage
  • ????????,????????????????????
  • Vital ingredient in optimising rumen development
