ESTIMASI NILAI REPITABILITAS DAN PERFORMA PRODUKSI UMUR LAHIR DAN SAPIH INDUK BABI PERANAKAN LANDRACE (The estimate of repitability value and performances at birth and weaning age of landrace crossbred)
The aims of this research were to estimate repitability coefficients of production at birth and weaning characters and to determine the average and standard deviation of landrace crossbreed sows. This research was carried out in two breeding farms namely the Instalation of Pig Breeding, village of Tarus, Kupang Regency and the Manise Pig Farm, Village of Oetete, Kupang City, East Nusa Tenggara. Materials used 15heads landrace crossbreed sows ( 15 heads ) which born and weaned piglets during the study periode. The number of piglets for the first parity was 151heads and for the second parity was 162heads. All sows was mated by artivicial insemination with boars of landrace crossbreed. Variables were liter size, weaning rate, birth weight, weaning weight and weaning rate. Results showed that landrace crossbreed sows had the average and deviation standard for the first and second liter size were 10.00±1.50heads and 10.73±2.40heads, respectively; for the first and second birth weight were 1.37±0.23kg and 1.68±0.34kg, respectively; for the first and second weaning weight were 6.42±0.38kg and 6.72±0.51kg, respectively and for the first and second weaning rate were 8.33±1.28heads and 8.68±1.43 heads; respectively. The average of litter size, birth weight, weaning weight and weaning rate between the first and second parity was no difference (P > 0,05). The value of repeatabitily for characters of liter size, birth weight, weaning weight and weaning rate were 0.32; 0.47; 0.49 and 0,42; respectively. In conclusion, the repeatabily value of litter size, birth weight, weaning weight and weaning rate from landrace crossbred sows were medium value and the performance of those characters between the first and second parity were no difference
PENGARUH LAMA EKUILIBRASI TERHADAP KUALITAS SEMEN BEKU BABI DUROC DALAM PENGENCER TRIS-MODIFIKASI DENGAN PENAMBAHAN KRIOPROTEKTAN (Effect of equilibration time on frozen sement quality of the duroc pig in tris diluents modification With.....
The purpose of this study was to test the influence of the equilibration time on the frozen semen quality of duroc pig in modified tris-egg yolk with the addition of extracellular cryoprotectants. Semen is collected twice per week using massage methods from two duroc males aged ±2.5 years which in good health and have been trained in semen colection. The design used is a completely randomized design with 4 tests and 3 treatments T1: equilibration time of 1 hour, T2: equilibration time of 2 hours, T3: equilibration time of 3 hours at a temperature of 50C. Observed parameters were motility, viability, abnormality, MPU, and recovery rate (RR). The results showed that motility, viability, abnormalities, MPU, and RR were higher (P<0.05) at 2 hours of equilibration (25.63±3.15%, 55.86±5.41%, 4.92±0.53%, 56.69±5.64%, 36.61±4.49%) compared to 1 and 3 hours (20.00±3.54%, 39.28±9.89%, 7.93±0.76%, 40.21±9.39%, 28.57±5.05%) and (15.00±4.08%, 32.19±7.0%, 8.41±0.70%, 32.71±7.07%, 21.43±5.83%). It was concluded the motility of duroc pig spermatozoa in the tris-modified diluents after 2 hours of equilibration reached 64.375% and 25.63% post thawing, but did not reach the requirement of 40% spermatozoa motility for artificial insemination. It was concluded that the sperm motility of Duroc pig in tris-modified diluent after 2 hours of equilibration reached 64.375% and 25.63% post thawing, but did not reach the standard of 40% spermatozoa motility for artificial insemination
The Estimate of Repitability of Performances at Birth and Weaning Age of Duroc Crossbred Sows
The aims of this study were to determine the average and standard deviation and to estimate repitability coefficients of production at birth and weaning characters of duroc crossbred sows. The study was carried out in two breeding farms namely the Instalation of Pig Breeding, village of Tarus, Kupang Regency and the Manise Pig Farm, Village of Oetete, Kupang City, East Nusa Tenggara (NTT). Materials used duroc crossbred sows ( 15 heads ) which born and weaned piglets during the study periode. All sows was mated artivicialy with boars of duroc crossbred. Variables were liter size, weaning rate, birth weight and weaning weight. Analysis of statistical description was used to determine the average and deviation standard of liter size, weaning rate, birth and weaning weights. Effects between paritas was analysed using t-test and the interclass correlation was used to calculate the coefficient of repitability. Results showed that duroc crossbred sows had the average and deviation standard for the first and second liter size 9.87±1.80 head and 10.67±2.58 head; for the first and second birth weight 1.30±0.26 kg and 1.47±0.47 kg, for the first and second weaning weight 6.01±0.49 kg and 6.47±0.61 kg .and for the first and second weaning rate 8.20±1.78 head and 8.53±2.23 head; respectively. The average of litter size, birth weight, weaning weight and weaning rate between the first and second parity was no difference (P > 0,05). The coefficients of repeatabitily for characters of liter size, birth weight, weaning weight and weaning rate were 0.48; 0.30; 0.46 and 0,52; respectively. In conclution, the coefficients of repeatabily of litter size, birth weight and weaning weight from duroc crossbred sows were medium and that for weaning rate was high value and the performance of characters between the first and second parity were relatively same
