Lifetime reproductive performance in female pigs having distinct reasons for removal

Autor: Gary D. Dial, Thomaz Lucia, William E. Marsh

Publikováno v: Livestock Production Science. 63:213-222

This study describes the reasons for removal of female pigs distributed across parity categories, and evaluates how parameters of lifetime productivity differ for females having distinct removal reasons. The study analyzed lifetime records ® from 79

Interactions between the associations of parity, lactation length, and weaning-to-conception interval with subsequent litter size in swine herds using early weaning

Autor: Yuzo Koketsu, Gary D. Dial

Publikováno v: Preventive Veterinary Medicine. 37:113-120

Sixteen farms having an average lactation length between 14.9 and 18.9 days were selected based upon producers' willingness to keep records of production and lactation feed intake. Data contained 9162 subsequent litter-size records abstracted from co

Publikováno v: Animal Reproduction Science. 52:153-163

Twenty-four pregnant gilts were assigned to four experimental treatments in a 2 x 2 factorial arrangement. The first factor was lactation length (12 vs. 21 days) (LL); the second factor was a provided amount of diet (FF, full feeding vs. low, 2 kg/da

Management factors associated with swine breeding-herd productivity in the United States

Autor: JinLiang Xue, Gary D. Dial, David Reeves, Vickie L. King, Yuzo Koketsu

Publikováno v: Preventive Veterinary Medicine. 35:255-264

A database containing 24 key production measurements was created by abstracting data files of 673 U.S. farms which participated in the PigCHAMP data-share program in 1995. Summary statistics for breeding-herd performance data were presented for the C

Factors associated with average pig weight at weaning on farms using early weaning

Autor: Yuzo Koketsu, Gary D. Dial

Publikováno v: Animal Science. 66:247-253

The objective of this study was to investigate the effect of various factors on average pig weight at weaning on farms using early weaning. Farms were selected based on average weaning age and whether they recorded lactation food intake and litter we

Influence of feed intake during individual weeks of lactation on reproductive performance of sows on commercial farms

Autor: Yuzo Koketsu, Vickie L. King, Gary D. Dial, J. E. Pettigrew

Publikováno v: Livestock Production Science. 49:217-225

The influence of average daily feed intake (ADFI) during different weeks of lactation on the reproductive performance of sows was investigated. Data contained 18243 farrowing and 15671 ADFI records for sows with lactation length between 7 and 22 days

Publikováno v: Theriogenology. 47:1445-1461

The objective of this study was to investigate the effects of various factors, including lactational feed intake, on the reproductive performance of sows in commercial herds. The 4 measures of reproductive performance were weaning-to-first-service in

Comparison of the accuracies of chemical and sensory tests for detecting taint in pork

Autor: JinLiang Xue, Gary D. Dial, Robert B. Morrison

Publikováno v: Livestock Production Science. 46:203-211

Chemical and sensory tests are widely used to detect boar taint in meat from entire male pigs. Chemical tests typically assess tissue levels of the compounds associated with taint, including 16-androstenes, like 5α-androstenone, and skatole. Sensory
