Sows (98 first parity and 104 second parity) were used to determine the effects of dietary lysine and valine on lactation performance. Treatments were arranged in a 2 x 3 factorial with two levels of lysine (.80 or 1.20%) and three valine:lysine ratios (80, 100, or 120% of lysine). For all sows, increasing dietary lysine increased litter weaning weight (P < .001) and litter weight gain (P < .002) and reduced sow weight loss (P < .001). Litter weight gain tended (P = .22) to increase with…

The effect of increasing the dietary valine-to-lysine ratio on sow metabolism, milk production, and litter growth.
TLDR
There was no effect of increasing the total dietary Val:Lys above 0.84:1 on sow metabolism and litter performance during lactation, and sow BW and back fat loss were similar for all sows.
Effects of dietary valine:lysine ratios on lactation performance of primiparous sows nursing large litters
TLDR
Dietary val:lys ratios of 0.80 and 0.85 do not affect the lactation performance of primiparous sows nursing large litters, but increase the arginine and threonine concentrations in milk as the dietaryval:lys ratio are increased.
Effects of Dietary Lysine Supplementation on the Performance of Lactating Sows and Litter Piglets during Different Seasons
TLDR
The results indicate that the influences of dietary treatment and season were independent and dietary lysine supplementation did not improve the performance of lactating sows and litter piglets, which was impaired by the warm season.
Effects of dietary valine concentration on lactational performance of sows nursing large litters. NCR-42 Committe on Swine Nutrition.
TLDR
Results indicate no benefit of elevated dietary valine for lactating sows nursing > or = 10 pigs and consuming a corn-soybean meal diet containing .90% lysine and .80% valine.

TLDR
88 and 113% dietary SID valine : lysine ratios were optimal to achieve minimum back fat loss and maximum piglet growth rate using a linear-break point model which exceeds the requirement of 85% that is estimated by the National Research Council (2012).
Effect of optimizing dietary valine-to-lysine ratio in late gestation or lactation on biochemical indices and performance of lactating primiparous sows

Influence of various lysine and threonine levels in feed mixtures for lactating sows on milk quality and piglet growth
The quality of produced milk and piglet growth were investigated in three groups of lactating Large White sows fed three mixtures containing different levels of lysine, threonine and crude protein.…
The effects of branched-chain amino acids on sow and litter performance.
TLDR
Results confirm the importance of dietary valine for increased litter weaning weight, independent of either additional dietary leucine or isoleucine, and meet or exceeded their suggested estimates relative to lysine using ratios derived from the National and Agricultural Research Councils.

Valine requirement of the lactating sow.
TLDR
The metabolic data support .53% dietary valine for the requirement of the lactating sow's requirement, although the maximum response in production parameters at .68% dietaryValine suggests that the requirement is above .53%.
The response of first-litter sows to dietary protein level during lactation.
TLDR
A two-phase linear regression model used to describe the relationship between N balance and dietary CP level established that sows required a diet containing > or = 202 g of CP/kg or 12.8 g of lysine/kg to maximize N balances during both stages of lactation.
Response of maternal-line sows to dietary protein concentration during lactation.
TLDR
The data suggest that dietary protein concentrations between 13.6 and 19.2% do not influence voluntary feed intake of lactating sows or weaning-to-estrus interval, and that postweaning interval to estrus interval was unaffected by dietary treatments.
Valine requirement of the high-producing lactating sow.
TLDR
It is demonstrated that increasing dietary valine for high-producing sows (21-d litter weights > 60 kg) results in improved litter weight gain.
Colostral milk fat percentage and pig performance are enhanced by feeding the leucine metabolite beta-hydroxy-beta-methyl butyrate to sows.
Three trials were conducted to test whether feeding the leucine metabolite beta-hydroxy-beta-methyl butyrate (HMB) would increase fat content of sows' milk and pig weight gain. All sows received a…
Quantitative influence of lysine and energy intake on yield of milk components in the primiparous sow.
TLDR
Lysine and ME intake had an interactive influence on yield of all milk components except lactose, demonstrating that the amount of lysine required to maximize milk production increased as ME intake increased.
Increasing valine, isoleucine, and total branched-chain amino acids for lactating sows.
TLDR
The independent increases in litter weaning weights from adding valine and isoleucine suggest separate modes of action in lactating sows.
Plasma prolactin and insulin changes on feeding leucine supplemented diet in rats.
TLDR
The status of these two hormones during lactation in rats given leucine supplemented diet is studied to study the relationship between prolactin and insulin and mammotropic actions.
Effects of valerate and isobutyrate on fatty acid secretion by the isolated perfused mammary gland of the lactating goat.
TLDR
The effect of isobutyrate indicated that valine acted as a precursor of milk iso-branched fatty acids after its metabolisation to isobutyryl-CoA.
Whole blood and plasma amino acid uptakes by lactating bovine mammary glands.
TLDR
Uptakes of individual amino acids from plasma were poorly correlated with uptake from whole blood, indicating that uptake data derived from plasma do not adequately represent whole blood amino acid uptake.
