Abstract: SIAGIAN, POLLUNG Ho University of the Philippines at College, Laguna. October, 1984. Comparative e of Yorkshire Landrace and Duroc Breeds of Swine. Professor: Dr. Valentino G. Arganosa The reproductive performance data of 3266 Yorkshire, ace and 1451 Duroc sows which farrowed from 1979 to November, 1983 and the productive performance of 1882 Yorkshire, 1100 Landrace and 881 Duroc I 3178 Yorkshire, 1806 Landrace and 1131 Duroc gilts 2,hoursmpleted their performance test in the same period in this study. different traits associated with sow productivity n om the Yorkshire, Landrace and Duroc were as umber of pigs born alive, 9.25, 9.22 and 7.78; cf pigs born dead; 0.86, 0.68 and 0.69; average litter birth, 10,11, 9.91 and 8.46; litter size at weaning, 7.87 and 5.05; weaning age, 36,12, 37,44 and 37041 stillborn pigs, 6.77, 5030 and 6.81 percent; -e, 8 percentage based on pigs born total, 75.35, 80.13 50 percent; weaning percentage based on pigs born 0.71, 84.77 and 64.71 percent; pig birth weight, 1.34, 1.49 and 1.52 kg; litter birth weight, 11.87, 13.15 1.37 kg; pig weaning weight, 5.98, 60 53 and 6.10 kg; ,litter weaning weight, 47.11, 51.67 and 34.69 kg; gestation 114.31, 114.73 and 114.29 days; age at first breeding, 273.37 and 269.79 days; age at first farrowing, 410.42 and 401.72 days; interval between weaning to conception, 25.23, 31.22 and 23.92 days; and the interval two consecutive farrowing’s, 172.07, 181.21 and days, respectively. The effects of breed on most of rent reproductive traits were highly significant year effect on the reproductive traits were also in many traits. Season effects were highly significant reproductive traits. averages of the different production traits of boars belonging to the Yorkshire, Landrace and Duroc breeds were: 0 kg, 166,96, 174.30 and 172.18 days; average daily 4, 727 and 763 g; feed efficiency, 2941, 2048 and .49; back fat thickness, 2.54, 2036 and 2,45 cm; selection index, 156, 149 and 151 and average daily feed consumption, .87, 1.79 and 1088 kg, respectively. The averages of the different production traits of gilts ,e longing to the Yorkshire, Landrace and Duroc breeds were age at 90 kg, 181080, 188092 and 185045 days; average daily gain, 670, 626 and 671 g; feed efficiency, 2.67, 2068 and 072; back fat thickness, 2051, 2039 and 2,40 cm; selection index, 131, 128 and 131 and average daily feed consumption, 071, 1.61 and 1078 kg, respectively.

SIAGIAN, POLLUNG Ho University of the Philippines at College, Laguna. October, 1984. Comparative e of Yorkshire Landrace and Duroc Breeds of Swine.
Professor: Dr. Valentino G. Arganosa
The reproductive performance data of 3266 Yorkshire, ace and 1451 Duroc sows which farrowed from 1979 to November, 1983 and the productive performance of 1882 Yorkshire, 1100 Landrace and 881 Duroc I 3178 Yorkshire, 1806 Landrace and 1131 Duroc gilts 2,hoursmpleted their performance test in the same period in this study. different traits associated with sow productivity n om the Yorkshire, Landrace and Duroc were as umber of pigs born alive, 9.25, 9.22 and 7.78; cf pigs born dead; 0.86, 0.68 and 0.69; average litter birth, 10,11, 9.91 and 8.46; litter size at weaning, 7.87 and 5.05; weaning age, 36,12, 37,44 and 37041 stillborn pigs, 6.77, 5030 and 6.81 percent; -e, 8 percentage based on pigs born total, 75.35, 80.13 50 percent; weaning percentage based on pigs born 0.71, 84.77 and 64.71 percent; pig birth weight, 1.34, 1.49 and 1.52 kg; litter birth weight, 11.87, 13.15 1.37 kg; pig weaning weight, 5.98, 60 53 and 6.10 kg; ,litter weaning weight, 47.11, 51.67 and 34.69 kg; gestation 114.31, 114.73 and 114.29 days; age at first breeding, 273.37 and 269.79 days; age at first farrowing, 410.42 and 401.72 days; interval between weaning to conception, 25.23, 31.22 and 23.92 days; and the interval two consecutive farrowing’s, 172.07, 181.21 and days, respectively. The effects of breed on most of rent reproductive traits were highly significant year effect on the reproductive traits were also in many traits. Season effects were highly significant reproductive traits. averages of the different production traits of boars belonging to the Yorkshire, Landrace and Duroc breeds were: 0 kg, 166,96, 174.30 and 172.18 days; average daily 4, 727 and 763 g; feed efficiency, 2941, 2048 and .49; back fat thickness, 2.54, 2036 and 2,45 cm; selection index, 156, 149 and 151 and average daily feed consumption, .87, 1.79 and 1088 kg, respectively. The averages of the different production traits of gilts ,e longing to the Yorkshire, Landrace and Duroc breeds were age at 90 kg, 181080, 188092 and 185045 days; average daily gain, 670, 626 and 671 g; feed efficiency, 2.67, 2068 and 072; back fat thickness, 2051, 2039 and 2,40 cm; selection index, 131, 128 and 131 and average daily feed consumption, 071, 1.61 and 1078 kg, respectively.
