patterns????? - Poorly balanced diets???????

34Poor environments increase risk of SARA
?????????????????

- Animal behaviour????
35Strategies 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???

?
37Starch levels can be reduced????????
38Better forage quality?????

39Increasing physically effective fibre increases
time being a cow!??????,?????????
40Keep 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????

- Add molasses to reduce sorting????????
41Forage as wide as her mouth!?????????
42Keep 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?????
43Enough room to feed???????
44Pectin 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??
??????????
45Measures 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???,????

acid - ?????????????
- Feeding high starch diets??????
- Using high feed rates per feed and/or per day
