AfiWeigh ™ Automatic Cow Body Weighing System Oded Nir (Markusfeld) Consultant to SAE Afikim Dealers Meeting, Dead Sea, Israel, 2008
2 AfiWeigh™ - Cows Body Weight Evaluation the energy balance f or backing up decisions such of feeding and breeding policy Monitoring stress and health Body weight & body condition score Reliability
AfiWeigh™ (1) Evaluation the energy balance In the dry period From calving to service
4 Loss of body weight in the dry period
5 When over the dry period do cows lose BW? (n=268) cows SJ
6 Diagnosis (risk factors for ketosis) loss of BW compared to loss of BCS in the dry period (odds ratios)
AfiWeigh™ Automatic cow body weighing system May we use BW instead of BCS for evaluation of Energy Balance?
8 Dry matter intake & energy requirements BCS compared to BW Calculations NRC 2001 Lactating cow, 4 th lactation, 46 DIM, 51.2 kg 3.5% FCM/day
10 Individual Cow Models (1) Should I inseminate or wait for the next heat?
11 Individual Cow Models (2) AFIfarm AFIfarm Calving & Fertility Data Health Traits Milk solids Body Weight Season
12 Individual Cow Models (3) AFIfarm AFIfarm The Chances of the Cow to get pregnant from the present AI are 35% Compared to 45% from the Next One
AfiWeigh™ AfiWeigh needs constant care
14 At drying off After calving r=1 Credibility of the Data: Correlations (r) of Body Condition Scores & Body Weights (1)
15 At 50 days in milk At drying offBCS r=.306**r=.449**At calving At 50 days in milk At drying offBW r=.846**r=.843**At calving Correlations (r) of BCS & BW (2) 273 cows
Correlations of BW in farms using AfiWeigh 7 countries It can, and should be done!
