The adjusted farrowing rate was similar to that in the control; however, the total number of piglets born was reduced when 2.5mg pLH was administered by vulvar submucosal route (12.3 vs.
Antibiotics added to the diet can improve a sow's reproductive performance, conception rate, litter size, and farrowing rate. As early as 1954, Stewart et al reported no significant effects of Chloromycetin on reproductive performance; however, the greater percentage of ova shed, represented by normal embryos in lots receiving Chloromycetin, suggested that the antibiotic has favorable effect on embryo survival [9].
However, the average farrowing rate in surveys of herds is often less than 80%--even the best farms have trouble keeping the farrowing rate above 90%.
The farrowing rate in the piggery decreased from an expected 82% to 60%; the number of live piglets declined in 27% of the litters born; the proportion of mummified and stillborn piglets, some with deformities, increased; and occasional abortions occurred.
Subsequent reproductive performance of all sows was evaluated and the following data were collected: weaning-to-oestrus interval (WOI), farrowing rate (FR), and the number of total piglets born (NTB).
The number of sows needed to produce 22,000 pigs from a sow herd of 1,000 sows with a decreasing farrowing rate is shown in the following figure.
The breeding barn staff has a great influence on the farrowing rate and the number of total pigs born to sows in the farrowing area.
Farrowing rate The number of farrowings/yr divided by the number of farrowing services.
High ambient temperatures during lactation above the evaporative critical temperature (i.e., 22[degrees]C; 1), reduces average daily feed intake (ADFI) with negative consequences on farrowing rates and reproductive performance in lactating sows due to their high nutrient requirements [1,2].
In addition, stall housed gilts observed more farrowing rates (97.6%) than ESF gilts (95.2%).
As an assistant to the person in charge of all sow production, this person specializes in breeding techniques that assure the highest possible farrowing rates. In a large unit, the Breeding Specialist could have advanced training in reproductive biology.
