Advances in low-protein diets for swine

Limiting Amino Acids in Low-protein Corn-soybean Meal Diets for Growing-finishing Swine 1 ,2

Experiments were conducted with growing and finishing swine to evaluate the effectiveness of various amino acid additions to low-protein corn-soybean meal diets. Two feeding experiments were conducted with growing swine each including a 16% protein positive control diet. In the first, a 14% protein diet served as the negative control while in the second trial it was a 12% protein diet. Amino ac...

Use of low-test-weight corn in swine diets and the lysine/protein relationship in corn

weight resulted in a slight reduction in the true metabolizable energy content of corn.! Since corn's primary contribution to swine diets is energy, we generally think that low-test-weight corn is of lower feeding value than normal-test-weight corn. However, the 1992 corn crop did not exhibit nutrient content typical of lowtest-weight corn. Field observations failed to demonstrate a consistent ...

Low Protein Diets for Gilts 773

T WO experiments involving 81 litters were conducted to determine the effect of low protein (45 g/day, from corn) and adequate protein (309 g/day, from corn and soybean meal) on reproductive performance of gilts. Gain during gestation was significantly decreased by the low level of protein, but litter size and pig weight at birth were not significantly affected by dietary treatment. Weight loss...

Advances in Swine Transcriptomics

The past five years have seen a tremendous rise in porcine transcriptomic data. Available porcine Expressed Sequence Tags (ESTs) have expanded greatly, with over 623,000 ESTs deposited in Genbank. ESTs have been used to expand the pig-human comparative maps, but such data has also been used in many ways to understand pig gene expression. Several methods have been used to identify genes differen...
