Effects Of Fasting And Transportation On Pork Quality Development And Extent Of Postmortem Metabolism, J.M. Leheska, D.M. Wulf, R.J. Maddock

Animal Science Faculty Publications

One hundred seventy-seven pigs were used to determine the interaction effects of fasting and length of transport prior to harvest on pork muscle quality. The study design was a 2 × 2 × 3 factorial, which involved two genetic sources, fasting (F) or no fasting (N) of pigs 48-h prior to harvest, and three transport times (0.5, 2.5, or 8.0 h) on a semitrailer to the packing plant. Genetic source was a significant source of variation (P < 0.05) for most composition and muscle quality variables. Fasting reduced hot carcass weight 3.6% (P < 0.05), but length of transport did not affect hot carcass weight (P > 0.05). There were no differences (P > 0.05) in percent lean among fasting and transport treatments. Fasted pigs had higher longissimus ...

A Comparison Of Lifetime Implant Strategies For Beef Steers, Robbi H. Pritchard, Kelly W. Bruns, Donald L. Boggs Jan 2003

A Comparison Of Lifetime Implant Strategies For Beef Steers, Robbi H. Pritchard, Kelly W. Bruns, Donald L. Boggs

South Dakota Beef Report, 2003

Lifetime implant strategies were developed and applied to steer calves. The design was intended for evaluating strategies rather than specific implants. Strategies involving increasing potency of products used at common stages of production. Initial implants were administered when calves were approximately 2 mo of age. Implants did not increase BW at weaning or after backgrounding (P > 0.10) although they did increase ADG 5% over non-implanted controls during backgrounding (P < 0.05). The influence of implants on ADG was more pronounced during the finishing phase of production. Implants increased (P < 0.05) finishing phase ADG 18%, DMI 7.2%, and feed efficiency 9.4%. Overall post-weaning ADG increased 12% (P < 0.05) due to implants. Performance results changed when evaluating data on a live versus carcass weight basis due to differences in dressing percent. Increasing potency of the implant strategies caused progressive increases (P < 0.05) in carcass weight and ribeye area. Implanted steers produced fatter carcasses than did non-implanted steers (P < 0.05). There were no advances in skeletal or lean maturity attributable to the potency of the implant strategy. The frequency of carcasses grading Average Choice or better declined with implants. Implant strategies had no relevant influence on shear force. Overall, 12% of carcasses had a shear force > 5.0 kg (undesirable).

Characteristics Of Cressbred Progeny Of Holstein Dams Sired By Different Beef Breeds: A Review, Bruce C. Shanks Jan 2003

Characteristics Of Cressbred Progeny Of Holstein Dams Sired By Different Beef Breeds: A Review, Bruce C. Shanks

South Dakota Beef Report, 2003

Excellent reviews of cattle breed comparisons or breed-cross comparisons have been previously reported by Franke (1980), Long (1980), and Marshall (1994). However, these reviews do not contain information on the calving ease, performance, carcass characteristics, or beef palatability of crossbred progeny of Holstein dams sired by different beef breeds. In many countries dairy females are commonly mated to beef sires; however, in the United States the use of this practice is somewhat limited. Nevertheless, some United States dairy production schemes utilize beef sires on surplus Holstein heifers and cows. Also, some large commercial dairy operations purchase replacement heifers from outside ...

Recommended Strategies For Odor Control In Confinement Beef Cattle Operations, Kent Tjardes, Alvaro Garcia, Hans Stein, Charles Ullery, Stephen Pohl, Christopher Schmit

SDSU Extension Special Series

Odors coming off a beef feeding operation are generated from three different sources: the feedlot facility, waste storage, and the land where the manure is applied. In some operations, the feedlot facility may also serve as the primary waste storage area. To reduce the total amount of odor generated from a beef feeding operation, odor generation and emission by each of these three sources needs to be reduced.

Gene Family Encoding Hordeum Vulgare Translation Elongation Factor 1 Alpha (Ef-1a): Assignment Based On Bioinformatic Analysis Of Cdna Sequences, Jackson Moeller

The Journal of Undergraduate Research

Search of international DNA database, Genbank, produced eight barley cDNA EFlα sequences with unique accession numbers. The length of these sequences varied from an incomplete 502 bp to a full length 1646 bp encoding a 447 amino acid protein. The knowledge that there are four EF-lα gene family members in barley led us to query whether all four genes were represented in the group of eight database submitted sequences. Also of great importance was the correct assignment of gene family member to its mRNA and protein expression profiles. Before we could begin to address the expression studies, we undertook the ...
