母猪

The rates of apoptotic granulosa cells in all kinds of follicles in immature gilts were ashigh as atretic follicles;it decreased significantly after injection of PMSG,but it was higherand lasted shorter than that of mature pig.

性未成熟仔母猪卵巢中各类卵泡颗粒细胞凋亡比例很高，接近闭锁卵泡的凋亡比例；注射PMSG后则各类卵泡颗粒细胞凋亡比例显著下降，但高于性成熟母猪注射PMSG后的凋亡比例，并且维持的时间也较短。

This system could detectsows oestrus while the environmental temperature lower than 23℃,andveracity of this system was higher than man watching while theenvironmental temperature higher than 23℃;This system could be used todifferent types pig housing,as a result,it has biggish applicationpotential in sow reproduction.

本系统能准确鉴定环境温度较低时(＜23℃)母猪的发情行为，环境温度较高时(＞23℃)，该系统可适用于各种不同结构的猪舍，这说明它在母猪繁殖生产上有较大的推广应用潜力。

The general linear model via least-squared method was further applied to study the relationship between litter performances described above and the presence of individual allele for parous sows in Landrace, Yorkshire and Duroc breeds.

以一般线性模式和最小平方法分析母猪个别遗传标记交替基因与其产仔性能之结果显示：一些标记交替基因与四个品种母猪的产仔性能有极显著相关并具正效应。

The results suggested for the pig (about 130kg average pregnance weight) in winter supply DE 26.51MJ in prophas (1～84 days) and 32.31MJ in anaphase (85days～parturition) daily,or DE 28.00MJ／day during pregnancy averagely can meet the requirement of the pregnance pi...

结果表明：平均妊娠体重130kg左右的四川白猪Ⅰ系初产母猪冬季怀孕时，妊娠前期（1～84d）日供DE26.51MJ，后期（85d～分娩）日供DE32.31MJ，全期平均日供DE28.00MJ，能够满足妊娠母猪的能量需要。

Effects of dietary energy on release of FSH and LH in prepubertal gilts ;2. Nine prepubertal gilts JunMu No.

作者探讨短期限饲对初情期前母猪和初产母猪繁殖机能的影响及其机理。

The result suggests that IGF-IR and EGFR might be involved in mediating the effects of energy intake on the development of reproductive system in prepubertal gilts.

结果表明：日粮能量水平显著影响初情期前母猪卵巢上两种生长因子受体的表达，高能量对表达有促进作用，有利于两种生长因子作用的发挥，从而利于生殖系统的生长发育；因此，IGF-1R和EGFR可能参与介导能量摄入对初情期前母猪生殖系统发育的影响。

The experiment was conducted to study the effects of digestible energy and true digestible lysine on performance, composition of gestation tissue and hormone levels of primiparous sows during early gestation (mating-on day 84 of gestation), and to find out optimal requirement for energy and Lys content of primiparous sows during early gestation.

本试验旨在研究日粮消化能和真可消化赖氨酸含量对初产母猪妊娠前期（配种～妊娠第84天）生产性能、妊娠物组成和血液激素水平的影响，得出初产母猪妊娠前期能量和赖氨酸的适宜需要量。

Total protein content in serum maintained the highest level (P＜0.10) and urea concentration in serum maintained the lowest level (P＜0.10) similar to the condition in primiparous gilts which might mean higher protein efficiency to maternal body and fetus.

2经产妊娠母猪血清雌激素浓度在妊娠期维持相对高水平；孕激素妊娠前期维持相对高水平，后期维持相对低水平，其繁殖性能较好，与初产母猪的情况一致。

This experiment was designed to investigated the effect of energy and lysine content of thediet on maternal body gain, total number born, litter weight, serum biochemical indexes and hormone level, by means of saturation-D best regression design, so as to improve the reproductive performance of primiparous sow and offer theoretical basis for feeding during gestation.

本试验旨在研究日粮消化能(DE，Digestible Energy)和真可消化赖氨酸(TDLys，True Digestible Lysine)含量对初产母猪不同妊娠阶段母体增重、胎儿数、窝重、血液生化指标和激素水平等的影响，为提高初产母猪的繁殖性能以及在妊娠期进行合理饲喂提供理论依据。

The relationship between climatic factors and sow′s reproductive traits were done to investigate the influences of climatic factors on sow′s reproductivity.

通过对湘潭种猪场1126窝母猪繁殖性能的测定及其与主要气候生态因子的相关分析，从而阐述气候因子对母猪繁殖力的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
