25
bison digestive physiology type
grazer
26
characteristics of grazer type
large rumen larger retention time feed few times per day capable of handling low quality fibrous feeds
27
characteristics of concentrate selectors
smaller rumen higher feeding frequency higher passage rate choose higher quality of feed
28
factors affecting feed intake
season/daylength age/sex/production/BCS forage quality
29
summer hormone trends
long days low melatonin high prolactin low GH
30
seasonal DMI trend for cattle and bison
bison: drop in winter cattle: similar DMI but digestibility gets worse
31
high fiber forage cascade in deer
high fiber - less time in digestive tract - lower nutrient absorption level - starvation
32
digestibility % trend seasonality
digestibility decreases in the winter in all species
33
time in digestive tract of 50% TDN grass hay in bison
78hr held longer to increase digestive capacity
34
cervids in summer on high and low quality feed
high: rapid complete digestion, weight gain low: no weight gain or production
35
cervids in winter on high and low quality feed
high: maintain weight low: moderate weight loss in small particles, advanced weight loss with large particles
36
bovine summer on low and high quality feed
high: weight gain and production low: inhibited production
37
bovine winter on high and low quality feed
high: maintain weight low: potential loss with small particles, advanced loss with larger particels
38
female weight change trend
low at calving slow increase to breeding increase for winter decrease through winter into calving
39
seasonal activities
spring-calving summer- growth and lactation fall- breeding and preparedness for winter winter- winter hibernation
40
factors affecting nutrient requirements (8)
digestive system environment pelage fat deposition age size stage or production BCS
41
consideration for feeding mineral
need to be out in the open with sufficient room
42
DMI bison summer and winter
summer is 1.4-1.8% winter is 2.2-3.5%
43
when does seasonal weight loss begin in bison
after puberty
44
spring compensatory gain
animal will gain back what they lost over the winter. not worth keeping weight up over winter unless feed cost is pretty low because of this. just let em do their thing
45
when do bison feel the cold
-30
46
bison HR and RR compared to cattle
lower HR and RR
47
bison fiber diameter
finer than cattle making it softer
48
benefits of thick hair and hide
resistant to ticks and biting flies wallowing/ dustbathing cattlebird interaction (scratching)
49
what types of forages do bison outperform cattle on digestibility
grasses and sedges
50
bison production cycle
breed july calve may
51
acceptable female weight loss in winter
10% BW
52
flushing methods for bison
rotate onto new pasture concentrates- oats forages with high TDN
53
risk of breeding too young
target breeding is at 2 yrs old if you do on 1yr they will skip yr 2
54
weaning time of year
jan/feb
55
risk factors of overfeeding grain
rumen acidosis liver abscess sore feet decreased breeding lifespan
56
feed formulation for 18-24 months old
heavy reliance of forages supplement energy based on BCS
57
how often do bison water
1x per day
58
mineral of concern in bison dose
copper maybe 15-25 mg/kg /d
59
3 bison advantages
reduced feed intake in winter to save costs lower critical temperature (-31) minimal calving assistance as long as fat is not built up in birth canal
60
castration of bison bulls
not done
61
bison feed conversion
12:1
62
bison ADG
1.7-1.9lb/d
63
ADG and FC tanks at d ____
170
64
dry lot size for bison
2x cattle
65
concentrate level for finishing ration
50-70%
66
bison step up program
1-3 steps no change in protein 2 energy steps
67
problem with finishing bison
large variability in rumen pH leading to issues with consistent feed intake
68
feeding bison heifer
smaller carcass and meat cuts 66% dressing weight finish sooner with more back fat than bulls
