How efficient are the current hyper-prolific lactating sows? (2/2)
In the previous paper, the effects of nutrient restriction and consequent catabolism during lactation on sow reproduction yield have been addressed. In the present paper, the efficiency of sows in using energy from feed and body mass is considered.
Arginine supplementation during lactation affects sow metabolism and improve litter performance
Sow metabolism during lactation is affected by arginine supplementation promoting litter weigh improvement.
Human chorionic gonadotrophin in early gestation improves sow fertility during summer
hCG stimulates growth of estrogenic follicles and CL function, and improves primiparous sow fertility during the summer months.
Feeding level during gestation affects farrowing and litter performance
Increasing feeding level during gestation may improve piglet body weight at birth but have a negative impact on feed intake and backfat loss during lactation.
Palygorskite dietary supplementation effects on back fat mobilization, leptin levels and oxidative stress in sows
The use of palygorskite in sow diets reduces oxidative stress in gestating sows.
Impact of maternally derived immunity on piglets’ immune response and protection against PCV2 after vaccination at different age
This study was aimed at evaluating the clinical protection, the level of Porcine circovirus type 2 (PCV2) viremia and the immune response (antibodies and IFN-γ secreting cells (SC)) in piglets derived from PCV2 vaccinated sows and themselves vaccinated against PCV2 at different age, namely at 4, 6 and 8 weeks.
Prevalence and factors associated with the occurrence of bacterial enteropathogens in suckling piglets in farrow-to-finish herds
The aim of the study was to determine both environmental and infectious factors, influencing occurrence of bacterial enteropathogens in suckling piglets.
Increasing energy intake during gestation, improvement for primiparous sows
Sow and litter performance in primiparous sows is directly affected by energy intake during gestation.
Dietary tryptophan: lysine ratio affects reproductive performance of lactating sows
The optimal Trp:Lys ratio for modern sows during lactation ranges between 0.22 and 0.26.
Perinatal dietary choline deficiency in sows
Dietary choline deficiency induces alterations in plasma choline metabolites which are evident at the end of lactation. Betaine and select FAs in milk are sensitive to maternal dietary choline deficiency and day of lactation. Alterations in concentrations of these nutrients may affect early-life neonatal development.
Minimize the nutrient deficiency in early lactation and improve milk yield
A better fit of nutrient requirements in early lactation improves sow milk yield.
Requirements of essential fatty acids for lactating sows
Dietary essential fatty acid supplementation in sow during lactation affects further reproductive performance.
Observations of sows and piglets housed in farrowing pens with temporary crating or farrowing crates on a commercial farm
The current study demonstrated that the farrowing system design can influence sow behaviour, with pens allowing for more interactions between sows and their piglets.
Coefficients of repeatability for colostrum and milk composition of PLW and PL sows over three consecutive lactations
It can be stated that the lactose content of sow colostrum in the first lactation could be indicative of a female's predisposition to produce colostrum and milk with similar lactose content over two consecutive lactations.
Effect of cross fostering on preweaning mortality
This study indicates that cross fostering was associated with lower risk for preweaning mortality.
