Organization of replacements V
On many farms the introduction of gilts is not homogenous. However, the introduction of a similar number of gilts to each productive batch would be ideal. How can we do this?
Farrowing programming II
The gestation period in the majority of sows is usually around 113 to 115 days. However, a percentage of sows can farrow normally up to 3 days before or after.
Organization of the replacements IV
Another convenient option for controlling the replacement entry is to incorporate the information on the breeding chart.
Organization of the replacements III
In the previous chapter we began to describe several systems for recording clearly and quickly the dates that gilts come into heat and for planning gilt service.
Hormone management (III)
When external administration of the hormonal product is stopped, the levels of progesterone fall.
Management of the breeding chart (II)
In the first part of management of the breeding chart we basically looked at how it can help us to control returns. In this second part we will look at other applications.
Dimension and design of the mating and control unit
The mating and control unit is one of the most important elements of a sow unit. Thus, it must facilitate a high pregnancy rate, high number of piglets, uniform body condition, sow longevity and a low return rate.
Stimulation and mating of sows in stalls (II)
So far we have seen different options for retaining the males and for stimulating the stalled sows that maximize speed and stimulus. Once stimulated, now we are going to mate them.
Stimulation and mating of sows in stalls (I)
Different systems of boar’s retention during stimulation and mating in stalls have already been seen. Now we are going to put it into practice.
Boar control during heat checking and mating
Both for heat detection and for mating, maximum efficiency is achieved if the sow is well stimulated.
