Relative prolactin-to-progesterone concentrations around farrowing influence colostrum yield in primiparous sows

In conclusion, a greater PRL/P4 ratio 24 h prepartum, characterized by lower P4 concentrations and a trend for greater PRL concentrations peripartum, led to increased colostrum yield in primiparous sows.

Effects of space allocation and parity on selected physiological and behavioural measures of well-being and reproductive performance in group-housed gestating sows

Our results suggest that at least at the chosen stocking densities, parity and space allocation have minimal effect on a number of commonly-used welfare measures.

The use of oxytocin in liquid semen doses to reduce seasonal fluctuations in the reproductive performance of sows

On the basis of the presented results, it should be noted that the use of oxytocin into insemination doses improves the farrowing rate and other parameters of the reproductive performance of sows.

Reproductive performance of sows can be predicted by high numbers of pigs born alive in parity one

High PBA in parity 1 can be used to predict that a sow will have high reproductive performance and lifetime performance.

The effect of numbers of frozen-thawed boar sperm and addition of prostaglandin F2α at insemination on fertility in pigs

These results indicate that AI using 2.0 × 109 FTS can result in acceptable pregnancy rates and litter sizes but with no measurable benefit for addition of prostaglandin.

Stimulate the sows as much as possible during their mating (G-spot)

Mating the stimulated sows eases the sperm transport to the oviduct, where they meet the ova.

Effect of sex of the pig on the sensory characteristics of the Biceps femoris and Semimembranosus muscles in dry‐cured hams

Organoleptic ham criteria for immunocastrated males hams were equivalent to those found for surgically castrated males and gilts hams, demonstrating the efficacy of vaccination in these study conditions.

Effect of plasma transfer on survival rates of low-birth-weight neonatal piglets

Under the conditions of this study, plasma transfer alone does not improve survival of low-birth-weight piglets.

Relationships among pigs weaned, preweaning survival and weaning weight with the number of piglets after cross fostering

Although piglet birth weight is the most influential factor affecting piglet survival other behavioral factors such as vitality and vigor of piglets at birth contribute to the overall likelihood of the offspring surviving.
