Hutterville Colony continues its improvement in weaning pigs per litter in its 575 sow herd for the past year:

Thanks to everyone for continuing as valued PEAK clients!

• lower feed cost per sow per year
• result in less variation in sow condition at time of farrowing and a higher proportion of sows in the target backfat range of 17 to 21 mm.

Based on an estimate of sow weight and backfat level at time of breeding, a table of feeding allowances has been developed.

 Table 1. Feeding allowance for gestating sows (day 0-day 100)

B. For those reluctant to use the cloth tape to take flank-to-flank measurements, the sows should be assigned to a weight class based on visual appraisal. For example:

Very light <150 kg

Light 150-180 kg

Medium 180-215 kg

Heavy 215-250 kg

Very heavy >250 kg

C. Also, for farms not using actual backfat measurements, they could substitute condition scores for the four backfat classes shown in the Table 1. Example: sows with condition scores 1-2, 2-3, 3-4, >4.

For this feeding program, the diet should have a nutrient content similar to that shown in Table 2.

Note also that the feeding period is from breeding date (day 0) to day 100 of gestation. It is recommended that first parity sows be fed no more than 2.2 kg per day for the first 2-3 days after mating. Older parity sows can be assigned to the feeding levels shown in Table 1 immediately after service.
