Erhualian and Yorkshire pigs early growth traits and genetic effects of maternal effect


Variation from dominates,[link widoczny dla zalogowanych], to 65.47 (P <0.01) (Table 3). Variations caused by dominant effects are small, and with the increase of age decreased. Because epistasis include additive × additive, additive × dominant, dominant X dominant three-part test were not elected by the significant level, it is not part of further resolution from the poor, but epistatic with the day-old an increasing trend to increase. Xiang-3 gene in the mother drum drum set should be the contribution of the total variance Table, C Qu Xiu deletion of ridicule tern-land which pit music eeffeem. o1otad Ⅷ I_tIon volume of Nanjing Agricultural University 20, 23, the value of maternal effects and genetic effects can be seen in Table 1 fan, Yorkshire pigs Erhualian maternal effect, birth weight was 0.1362kg, 20El age weight u3332kg. 60 day weight of a 0.8260kg; Yorkshire pigs Erhualian additive effect of the value of the three were: o. 0931. O. 3929 and 2.3184g. Dominant effect on pig weight at 60 days less affected, and the dominant value is only 0.1128kg. Table 4 Erhualian, Yorkshire pigs early growth of Rotary Park and the base effect of maternal effects estimated bit Table4Estimationofm-te-hu landgcneeHecuonearlygrow & eyelashes What the roundworm EI l l3 discussed several sndLWp Farm lot of studies have shown that pigs from birth to 8 months of age, body weight positive correlation between the particular and individual weight weaning and 6 months of age. Q there is a strong correlation between body weight. Zhang Wencan reported 0: Taihu pig weaning weight and a weight of 6 month old phenotypic correlation and genetic correlation were 0.56 and 0.64. Ge Yun-shan and other comprehensive Jinhua pig breeds in four key growth areas of genetic traits associated with that: weaning weight and 4 months of age were weight, weaning weight and 6 months of age were heavy, 4-month weight and between 6 months of age was re- strong correlation. Early growth performance and final performance related question offers the possibility of early selection. In addition, the early growth of piglets good strong disease resistance, breeding rate. Therefore, enhancing the development of early growth performance of pig production and improve economic efficiency is important pig. Effect of early maternal performance of pigs, which results from the reciprocal cross differences to be confirmed. Xuzhen Ying et al reported that most of: Ha White pigs with the people orthogonal weight at birth and weaning were lower than on the anti-cross combination. The test also found that individual and sophomore second largest birth weight individuals and 20 days there was a significant difference in weight, but 60 days back on the reciprocal crosses consistency. Subdivision of the total variance found: With the increase of age, maternal effects decreased at 60 days of age the proportion of maternal effect of the total variation of 88.89 has been reduced to 4.49 when newborn, while the steady increase in additive effect has total variation 65.42, this time due to additive gene mutation accounts for a dominant position. Landrace pigs with the people of the reciprocal cross tests were found: birth litter weight traits difference between the larger rate of reciprocal advantage, and weaning weight to narrow the gap between the two characters, to fattening period, daily weight gain between the two traits have No difference. This test seems to be that the above reports, maternal effects only affect the early growth traits, little effect on the final productivity. However, according to Xu Zhenying and other reports: China and Kazakhstan F-30 to 60,60475 and 75490kg stages of fat 'education El weight gain during the Han people more than a generation 6.5,9.02, and 21.96 F. Therefore, the maternal effect on the productivity of the final yet to be further clarified.
