The development of reproductive functions in Fengjing gilts:5 gilts in each of 5 groups,were mated at first to fifth oestrus,with concep- tion rates of 20%(1/5)、100%(5/5)、100%(5/5)、100%(5/5)and 60%(3/ 5),and ovulation rates of 13.0、12.2、14.8、14.8 and 16.6 respectively. There were no significant difference between individual oestrous cy- cles(P>0.05),or between oestrous cycles and pregnancy duration in the higher values of progesterone concentration(P>0.05).

The systematic research on 76 Jinhua pigs of different ages in days shows that the sexual maturity of the male pigs is earlier. The peak of the development of the genital organs generally appears in the period of 60-120 days after birth. The testicle, spermatic duct and external genitalia develop comparatively more quickly and the sexual accessary gland has a tendency of belated maturity. On the 45th day the cavity in the seminiferous tubule begins to form and then on the 60th day it can be seen in every seminiferous...

The systematic research on 76 Jinhua pigs of different ages in days shows that the sexual maturity of the male pigs is earlier. The peak of the development of the genital organs generally appears in the period of 60-120 days after birth. The testicle, spermatic duct and external genitalia develop comparatively more quickly and the sexual accessary gland has a tendency of belated maturity. On the 45th day the cavity in the seminiferous tubule begins to form and then on the 60th day it can be seen in every seminiferous tubule, and sperm appears in 3/7 of the individuals. There is sperm in all the. individuals on the 75th day. The young boar shows the sexual behaviour of mounting on 56.1th±1.16 days, when the. body weight is 8.25 ±0.35kg; the penis outstretches from the foreskin on 67.12th±1.28 clays, their body weight was 10.98 ± 0. 45kg; the first projection of semen appearson 69.2th± 1.33 days, with body weight at 11.3±0.44kg; the first normal sperm appears on 75.35th ± 0.86 day, their body weight at 11.93 ± 0.40kg, judging by the above standard as index of puberty, the puberty of Jinhua pig may be set at approximately 75 days after birth. About 3.5 months after birth the semens of the male pigs reach the normal standard and have the normal fertilization ability. The young boar has reached sexual maturity. During this period, the testosterone content in blood increases quickly and reaches 347.08 ng/100ml on the 120th day. It indicates that there's a close relation between the lesloserone content and the course of development of the sex function. Six months after birth, the quality of the semen has fundamentally reached the level of the adult male pigs and can be considered roughly as the month for first mating.

通过对76头不同日龄金华公猪进行系统研究表明:公猪性成熟较早,生殖器宫发育的增长高峰一般出现在60~120日龄阶段,睾丸、输精管道和外生殖器的发育较快,副性腺有较后熟的趋势。45日龄时睾丸曲细精管部分见有腔裂;60日龄时各个体曲细精管均有腔,3/7的个体已出现精子;75日龄时各个体均有精子。出现性爬跨行为在56.1±1.16日龄,体重8.52±0.35公斤;阴茎伸出包皮为67.12±1.28日龄,体重10.98±0.45公斤;初次射出精液为69.2±1.33日龄,体重11.3±0.44公斤;精液中首次出现形态正常的精子为75.35±0.86日龄,体重11.93±0.40公斤。因此,金华公猪的初情期为75日龄左右。3.5月龄左右精液质量已达常规输精标准,且有正常受精能力,已达到性成熟期。在此期间,血液中睾酮含量增长较快,120日龄的睾酮含量达347.08ng/100ml,显示出与性机能发育进程密切切关。6月龄时精液品质已基本达到成年公猪水平,可作为开始初配的大致月龄。

Observations on the reproductive characteristics of Hubei White Line Ⅲboars had been investigated. The young boar first exhibited the sexual behaviors of mountingand extending of penies were at age of 98 days with 37Kg of body weight. whereas the ageof first semen collection was at 130 days with 49Kg of body weight. The young boar with62-65Kg of weight which were 150-155 days after birth were able to fertilize a sow.The testis and epididymis index number began to increase rapialy from 90 days after birthand...

Observations on the reproductive characteristics of Hubei White Line Ⅲboars had been investigated. The young boar first exhibited the sexual behaviors of mountingand extending of penies were at age of 98 days with 37Kg of body weight. whereas the ageof first semen collection was at 130 days with 49Kg of body weight. The young boar with62-65Kg of weight which were 150-155 days after birth were able to fertilize a sow.The testis and epididymis index number began to increase rapialy from 90 days after birthand reuched peak by 180 days old. It was found that there were a lot of sperms in theseminiferous tubules of the testis and a few in the ductus of epididymis, at 120 days old.The testosterone contents in the plasma increased rapidly from 75 to 165 days and reached856ng/100ml on the 165th day. The quality of the semen of the young boarapproximated to that of adult boars at 240 days old. The above facts suggested that thepuberty and sexual maturity period for Hubei white Line Ⅱ boar were 120 and 150 daysold respectively. The first mating time were in the period of 240-270 days after birth.

对湖北白猪Ⅲ系公猪的繁殖特性进行较系统的研究表明:小公猪初次出现性爬跨并伸出阴茎的日龄为98天,体重37公斤;第一次采得精液的日龄为130天、体重49公斤。最早能使母猪怀孕的日龄为150~155天、体重62~65公斤。从90日龄开始,睾丸和副睾指数迅速增加,180日龄时达高峰。120日龄时睾丸曲细精管中出现较多的精子,副睾管中有少量的精子。血液中睾酮含量从75日龄至165日龄上升很快,在165日龄时达856ng/100ml。240日龄的精液质量接近成年公猪的水平,从而认为湖Ⅲ公猪在120日龄进入初情期;150日龄进入性成熟期;初配期可在240~270日龄。
