Protein metabolism in the lactating sow

A series of experiments were conducted to examine factors affecting feed intake and protein metabolism in the lactating sow. The primiparous sow exhibits poor appetite during the initial phase of lactation in relation to her requirements for production. The early phase of lactation is associated with a high plasma tryptophan to branched-chain amino acid (BCAA) ratio. High plasma tryptophan to the branched chain amino acids is associated with increased tryptophan entry in the brain and serotonin secretion which in turn is involved in the depression of feed intake in other species. The effect of decreasing the ratio of tryptophan to the BCAA in the sow did not increase feed intake, but rather decreased it. The leaner genotype sows tended to respond to an increased dietary BCAA by minimizing body weight loss during lactation.
