Calf-fed Holstein steers (n = 115; 449 ± 20 kg) were utilized in a serial harvest experiment. A baseline group of five steers was harvested after 226 d on feed (DOF), which was designated day 0. The remaining cattle were assigned randomly to 11 harvest groups, with slaughter every 28 d. Cattle were either not (CON) or were fed zilpaterol hydrochloride for 20 d followed by a 3 d withdrawal (ZH). There were five steers per treatment in each slaughter group ranging from days 28 to 308. Whole carcasses were divided into lean, …

The objective of this study was to evaluate the effect of timing of electrical stimulation on free calcium concentration, calpain-2 activity, Warner-Bratzler shear force (WBSF), and consumer sensory analysis. Twenty-three beef steers were harvested and stimulated (S) using extra-low voltage or not stimulated (NS), at exsanguination and/or 1 h postmortem, resulting in 4 different stimulation treatments: NS-NS, NS-S, S-NS, or S-S. Samples were removed from the longissimus lumborum (LL) and semimembranosus (SM) for free calcium and calpain-2 analysis on days 1, 4, and 14 postmortem. WBSF and sensory analysis steaks were removed on day 4 and frozen (4 d) or …

Genus and Species. Sus scrofa.

Locus. Porcine calcitonin (CALC) gene.

Source and Description of Primers. Primers, CCA1F and CCA1R, were designed from canine calcitonin sequence (GenBank Accession no. AJ271090) to amplify genomic porcine DNA. Using sequence obtained from the amplified PCR product, additional pig-specific primers (CIPBF, CIPBR, CIPCF, CIPCR) were designed.

Primer Sequences. CCA1F: 5′-CAC TTT GGA TTG GCC GCG C-3′; CCA1R: 5′-ACC AGG GCA GCC AGC AGG A-3′; CIPBF: 5′-AAC TTC CCA CTC TGC ACA CT-3′; CIPBR: 5′-AGA CCA AAC TTC AGC AGG AT- 3′; CIPCF: 5′-TTC TCC TTC CTC TGC TTC TG-3′; CIPCR: 5′-GCA AAC CCA ATA …

Bioavailability Of Calcium In Sun-Cured Alfalfa Meal And Effect Of Dietary Calcium Concentration On Bone And Plasma Characteristics During Two Phases Of Gestation In Gilt, G. L. Walker, D. M. Danielson, E. R. Peo, Jr., R. F. Mumm

Department of Animal Science: Faculty Publications

A study was conducted with gravid gilts to determine the bioavailability of Ca in sun-cured alfalfa meal (AM) and the effect of dietary Ca concentration on bone and blood characteristics during two phases of gestation.

Effect Of Grain Source And Dietary Level Of Oat Hulls On Phosphorus And Calcium Utilization In The Growing Pig, R. L. Moser, E. R. Peo, Jr., B. D. Moser, A. J. Lewis

Department of Animal Science: Faculty Publications

Three metabolism trials were conducted to determine the effect of grain source and dietary level of oat hulls on dry matter digestibility, P and Ca retention and intestinal phytase activity of growing pigs. Twenty-four crossbred pigs (39 kg)were used. Dry matter digestibilities of corn-based diets were greater (P<.01) than grain sorghum-based diets (74.7 vs 63.5%). Diets containing 10% oat hulls had lower (P<.01) dry matter digestibilities than diets containing no oat hulls (64.0 vs 74.2%).

Effect Of Level Of Dietary Calcium-Phosphorus During Growth And Gestation On Performance, Blood And Bone Parameters Of Swine, R. D. Nimmo, E. R. Peo, Jr., B. D. Moser, A. J. Lewis

Department of Animal Science: Faculty Publications

One-hundred and ninety-two crossbred weanling gilts (7.25 kg) were assigned to one of two treatments - (A) .65% Ca, .50% P or (B) .975% Ca, .75% P - and fed to an average weight of 92.8 kilograms. Average daily gain (.65 and .67 kg, respectively) and feed/gain were not affected by dietary treatment, but average daily feed intake was lower (P<.05) for gilts on treatment A (1.87 vs 1.95 kg).

Effect Of Level Of Dietary Calcium-Phosphorus During Growth And Gestation On Calcium-Phosphorus Balance And Reproductive Performance Of First-Litter Sows, R. D. Nimmo, E. R. Peo, Jr., J. D. Crenshaw, B. D. Moser, A. J. Lewis

Department of Animal Science: Faculty Publications

Twenty-four bred gilts were used in a Ca-P metabolism trial. Twelve gilts were fed gestation treatment A (13 g Ca, 10 g/day), while the other 12 were fed gestation treatment B (19.5 g Ca, 15 g P/day). One-half of the gilts in each treatment group were fed .65% Ca, .50% P from 7 to 94 kg, and half were fed .975% Ca, .75% P for the same period. Treatment B gilts excreted more (P<.005) fecal and urinary P. Twenty-four first litter sows fed the same treatment diets during growth and gestation and given .75% Ca, .50% P during lactation were used in a Ca and P balance trial conducted from day 38 to 42 of lactation.

Influence Of Age, Sex, And Calcium And Phosphorus Levels On The Mechanical Properties Of Various Bones In Swine, T. D. Crenshaw, E. R. Peo, Jr., A. J. Lewis, B. D. Moser, D. Olson

Department of Animal Science: Faculty Publications

Seventy-two 4-week-old pigs were randomly assigned by sex (gilts, barrows, boars) to two dietary treatments and four age periods for determinations of the effects of age, sex and Ca and P levels on the mechanical properties of various bones in swine.

Response Of Different Genetic Lines Of Boars To Varying Levels Of Dietary Calcium And Phosphorus, R. D. Nimmo, E. R. Peo, Jr., B. D. Moser, P. J. Cunningham, T. D. Crenshaw, D. G. Olson

Department of Animal Science: Faculty Publications

Two experiments were conducted to determine the effect of various levels of dietary calcium (Ca) and phosphorus (P) on performance, soundness and blood and bone parameters of different genetic lines of boars fed under variable environmental conditions. The first experiment compared different genetic lines of boars fed two levels of dietary Ca and P. Forty purebred (Large White) and Nebraska Gene Pool boars were allotted by breed and initial weight to two levels of dietary Ca and P (.65 Ca/.50% P and 1.3% Ca/1.0% P).

Effect Of Various Levels Of Dietary Calcium And Phosphorus On Performance, Blood, And Bone Parameters In Growing Boars, R. D. Nimmo, E. R. Peo, Jr., B. D. Moser, P. J. Cunningham, D. G. Olson, T. D. Crenshaw

Ninety-six 8-kg crossbred boars were initially allotted to three dietary levels of calcium (Ca) and phosphorus (P) - (A) .65% Ca; .50% P; (B) .975% Ca; .75% P and (C) 1.3% Ca; 1.0% P - to determine the effects of the different levels on average daily gain (ADG), average daily feed intake (ADFI), feed to gain (F:G) and certain blood and bone parameters.
