2022-07-12

Breeding sow farm production procedure design is one top important issues to start a new farm, now we will learn and analysis one sample 630 breeding sows pig farm production procedure desgin.

Basic breed sow prodction procedure design data:

Sow cycle = 114 pregnancy days + 28 lactation days + 5 service days =147 days

147 divide by 7 days(1 week) =21 groups

Farrowing house in the Breeding sow farm production procedure design

  • 630 sows /21 groups = 30 sow per week
  • Farrowing crates size is 1.8m by 2.4 m
  • Piglets are wean exactly 28 days after lactation

From the calculation, each sow is weaned of approximately 11 piglets at 8kg per piglet

So in total, we get about 30 sows X 11 piglets which are 330 piglets.

So according to the breeding sow farm production procedure design,  sow farrowing area requires 5 farrowing units house with each unit house containing 30 farrowing crates.

Getation house in the Breeding sow farm production procedure design

Insemination section: 30 sows + 20% (for sows which did not get pregnant) = 36 sows //

3 groups of 36 sows = 108 crates (this crates will be in 9 different pens/sections)

Explanation

23 insemination days divide by 7 days (1 week) = 3 groups of 36 sow each. (The three groups are further divided into 9 subgroups of 12 sows in 12 crates per pen each to avoid overcrowding at the insemination pens.

  • Five days after weaning, the sows are expected to come back to the insemination house
  • 23 days after the insemination, we will carry out a pregnancy test
  • Sows confirmed pregnant will be moved to the gestation section while those found not pregnant will be moved to the next group to be inseminated again
  • 8 boar pen places

Gestation section: In the gestation area, we will have 12 groups of 30 sows = 360 crates for gilt and sows

Analysis;

114 pregnancy days – 23 insemination days – 5 days (time before farrowing in farrowing crates) =

86/7 days (1 week) = 12 groups

So 12 groups of 30 sows = 360 gestation crates

In this area the breeding sows will spend around 86days

Note: 30 sows are to stay in 30 crates in a gestation pen. The dimension of the gestation pen should be so that the sows can leave their crates and walk freely within the pen where their crates are and go back to their crates for feeding, drinking and also routine checks by the attendant, which is to meet the each sow animal welfare requirement

SUMMARY OF GESTATION HOUSE ANALYSIS

Insemination Area: 3 groups of 36 sows = 108 gestation crates for insemination

Gestation Area: 12 groups of 30 sows = 360 gestation pen for gestation area

Waiting Area: 650-(360 + 108) = 182 piglets. Thus I would want 18 big crates for 10 sows each, and 8 boar crates. The reason is because in my region, it is not easy to come by good sow breeds and therefore buying on a weekly basis will be difficult and thus I plan to buy as much as I can from a reputable farm.

So according to the breeding sow farm production procedure design,  in total, we have 468 (2.3m by 0.65m each) gestation crates and 18 bigger crates (of say 4.6m by 6m each) and 8 boar crates of (2.3m by 2m each). This to me is lesser than your earlier drawing of 600 crates of 2.3m by .65m each and 52 back up crates 2.3m by 3m each.

Weaning house in the Breeding sow farm production procedure design

Nursery: 8 groups of 330 weaners

Explanation

We wean them from 7kg life weight up to 28kg life weight in the nursery pen, in this time they will grow at an average of 420g every day.

28kg – 7kg = 21kg / 0.42kg/day = 50 days / 7 days (every week we have a new group) = 7 groups plus a visual group for moving and cleaning this means in total we have eight groups of weaners in the barn.

Note: The 330 piglets weaned each week, will attain 30kg live weight after a period of seven weeks.

At 2.2% mortality rate

Consequently, we will be moving at least 322 growers to the finisher compartment each and every week.

WEANING HOUSE ANALYSIS SUMMARRY

So according to the breeding sow farm production procedure design,  the weaning house drawing should have 8 units. Each unit will have 16 individual crates (of 3*3m or a dimension enough to accommodate 22 piglets from 2 farrowing) .So by my rough estimate, I am looking at a total weaning dimension of 48m by 32m or a little more(arranging 16 crates in one column/unit ,while total column/units = 8.

Finishing house in the Breeding sow farm production procedure design

Finisher: 16 groups of 322 growers

After the nursery, the grower will attain a live weight of 112kg in the finisher compartment. In this time they will grow at an average of 820g every day

112kg – 28kg = 84kg / 0.8 kg/day = 105 days / 7 days (every week we have a new group) = 15 groups plus 1 additional compartment for cleaning and dry time after cleaning

Mortality of 1%

Note: Each week, we will sell at least 319 finishers out of the fattening pen, which have spent 15 weeks in the Finisher compartment to the market with an average live weight of 112kg.

319 animals x 112 kg live weight = 35,728kg of live animals

112kg live weight x 75% dressing percentage per animal = 84kg carcass weight

319 animals x 84kg carcass = 26,796kg of pork every week

FINISHING HOUSE ARRANGEMENT

So the weaning house drawing should have 16 units. Each unit will have 16 crates of approximately 3*6m size per crate, and thus each crate will accommodate approximately 22 finishers. So by rough estimate, the dimensions of the finishing house will be 64*96m depending on arrangement of 16 crates in one unit/column then into 16 columns.

The finishing house can be two houses if you think that the above dimension is too big for one house in terms of ventilation and other factors. If it will be two houses;

We will have 8 units. Each unit will have 16 individual crates (of 3*6m per crate or a dimension enough to accommodate 22 finishers from 2 farrowing) .So by my rough estimate, each house weaning dimension will be 32*96m or a little more (arranging 16 crates in one column/unit, while total column/units = 8.

By this means, according to the Breeding sow farm production procedure design we produce every week 26.8tons of pork for the market
