In Exp. 1, 144 pigs used .1% dietary a soybean meal- or milk protein-based diet performance function. Pigs fed from d 7 14 after weaning had lower ADFI (P < .01) and, although not significant, ADG was for than control diets. However, no differences observed function...

A total of 904 weanling pigs were used to investigate the effects 1) spray-dried porcine plasma (SDPP), 2) blends SDPP and blood meal (SDBM), 3) added dietary methionine in a SDPP-based diet on starter pig performance.

A total of 84 sows (PIC Line 1050) were blocked according to day farrowing and parity allotted in a 2 x factorial arrangement treatments with lactation feed intake (ad libitum vs. restricted) creep feeding (no yes) as factors. Sows fed for ad libitum-fed) allowed free access common diet (3,503 kcal ME/kg, 0.97% standardized ileal digestible Lys), restricted (restricted-fed) 25% less than libitum-fed sows.

Abstract From November 2021 to February 2022, 37 swine nutritionists representing 29 production systems and 8 nutrition supplier companies in the United States were surveyed about added vitamin trace mineral concentrations diets. Respondents asked provide premix concentrations, inclusion rates, weight ranges associated with feeding phases. Survey participants represented 4.38 million sows, or 72% of U.S. industry. Data compiled into three nursery phases (phase 1, weaning 7 kg; phase 2, 11 3,...

We conducted two experiments to evaluate the effects of added choice white grease on performance and carcass merit barrows gilts reared under commercial conditions. Pigs were housed either 20 (Exp. 1) or 25 2) per pen provided 0.67 m2 space pig. Diets based corn soybean meal fed in a form. The proportion was increased diets with fat maintain same calorie:lysine ratio all within weight phase. In Exp. 1, 480 pigs 0, 2, 4, 6% fat.

Lactating, primiparous Landrace × Yorkshire sows were used to characterize LH secretion during lactation in that experienced an early ( < 9 d; n = 14) or late > 15 9) return estrous postweaning and evaluate the relationship between blood metabolites. Twenty-three fed one of nine corn-soybean meal diets achieve a matrix lysine (15 45 g/d) energy (6.5 16.5 Mcal ME/d) intakes range metabolite concentrations return-to-estrus intervals. Blood samples for analysis collected every min 6 h on d 0,...

We conducted two experiments to evaluate the effects of dietary energy density and lysine:calorie ratio on growth performance carcass characteristics growing finishing pigs. In Exp. 1, 80 crossbred barrows (initially 44.5 kg) were fed a control diet or diets containing 1.5, 3.0, 4.5, 6.0% choice white grease (CWG). All contained 3.2 2.47 g lysine/Mcal ME during (44.5 73 (73 104 kg), respectively. Increasing did not affect overall ADG; however, ADFI decreased feed efficiency (Gain:feed ratio;...

One hundred eight high-lean-growth gilts (34.4 kg BW) were used to determine the dietary lysine requirement maximize growth, carcass characteristics, and protein accretion from 34 72.5 BW. The experiment was a randomized complete block design; initial BW served as blocking factor. Six treatments included, ranging .54 1.04% (.10% increments) digestible (.69 1.25% total lysine). Pigs housed in pens of three, with six replicate per treatment. Pig weights feed consumption collected weekly...

The organism, common inhabitant gut animals and humans, major nosocomial pathogen responsible for variety infections humans sporadic In swine cattle, E. faecium-based products are growth promotion functional health benefits. objective this study was to utilize whole genome sequence-based analysis assess virulence potential, detect antimicrobial resistance genes, analyze phylogenetic...

A trial was conducted to biochemically explain the decreased lipid deposition and increased protein accretion observed in pigs fed carnitine. Our hypothesis that an increase ratio of acetyl CoA:CoA-SH produced by stimulation fatty acid oxidation supplemental L-carnitine may decrease branched-chain alpha-keto dehydrogenase activity pyruvate carboxylase activity. Such changes could reduce oxidative loss amino acids provide more carbons for biosynthesis. Yorkshire gilts (n = 36; 12 per...
