This study used the technique of histoautoradiography to analyze the variation of LH binding in sow follicles during the preovulatory period. Estrus was synchronized by methallibure to obtain a reference point for dating the onset of the follicular phase of each sow in the experiment. In follicles increasing in diameter from 2.6 mm at days 0 and 1 of the follicular phase to 6.6 mm at day 6, granulosa 125 _oLH or 125 -pLH binding increased by 14 times while that of the theca interna increased by 2. The binding of these hormones remained high during and after the end of the ovulatory LH surge, at least until several hours before ovulation. Variations in plasmic as well as intrafollicular LH levels were radioimmunologically assayed. High intrafollicular levels of estradiol-1 7p at day 3 would explain the large increase of granulosa LH binding between days 4 and 5-6, in turn causing the intrafollicular level of progesterone to rise at day 5. These results indicated an interdependence between hormonal levels and target cell receptivity.

A technique for permanent fistulation of the bile duct, associated with a permanent fistulation of the duodenum allowing continuous reintroduction of the collected bile, was used to investigate the level and daily kinetics of biliary excretion in the conscious pig. Seven Large-White pigs of 45 kg live weight were fistulated. Volumes and total excreted bile salts were measured in hourly samples. Results show that within 24 hrs.the volume of the collected bile was about 2100 ml and the total amount of bile salts about 37 g. The bile excretion (volume and bile salts) was minimum before the morning meal (9:00 a. m.) and the total amount of the excreted bile salts immediately increased after diet intake. Within 2 hrs. after the morning and afternoon meals, values were about 300 p. 100 higher than those determined at 9:00 a. m. This increase was essentially the result of the excretion of a highly concentrated bile (200 to 300 p. 100 more than the values at 9:00 a. m.). On the other hand, the bile volumes were only affected 2 to 3 hrs. after diet intake.

were applied after expulsion of the first fetus. A simple manipulation of the female or a change of territory did not modify the whole expulsion phase but increased variability in the birth of the second fetus. By comparison, a strong stress lengthened the duration of expulsion and influenced the time intervals between the first births. A comparison of these results with those obtained after adrenalectomy indicated that the inhibitory effect of a strong stress was probably due to maternal adrenal epinephrin secretion. In the second experiment, a stress was applied before labor in normal rats submitted to two light regimes. In these conditions, the treatment essentially stimulated the last parturitions, which occurred earlier than in control animals.

The apparent digestibility of a diet was studied either after ligature of the bile duct or after discontinuous removal of bile secretion in the growing pig. Feces and urine were collected during a 10-day period in bile duct-ligated pigs, and over three 5-day periods in bile-fistulated pigs. The latter were subjected to three treatments each over the three periods : 1) re-entry of bile into the duodenum ; 2) introduction of a salt mixture (Na : 150 meq/1 ; CI : 120 meq/1 ; HC0 3: 40 meq/1) 3) no re-entry of either bile or the salt mixture. Apparent energy digestibility was mainly affected after ligature of the bile duct (-31.6 p. 100) or after removal of bile from the intestinal lumen (-23 p. 100). This decrease was essentially due to a decrease in the total lipid apparent digestibility (― 53 p. 100 after bile duct ligation and ― 31.7 p. 100 after bile removal). Apparent nitrogen and energy derived from carbohydrates digestibilities were unaffected. In the fistulated pigs the intraduodenal introduction of the salt mixture did not improve decreased apparent digestibilities.
研究了生长猪在结扎胆管或间断去除胆汁分泌后对饲粮的表观消化率。胆管结扎猪在10天内收集粪便和尿液，胆管瘘管猪在3个5天内收集粪便和尿液。后者分别在三个时期进行三种治疗:1)胆汁重新进入十二指肠;2)引入盐混合物(Na: 150 meq/1;CI: 120 meq/1;hc30:40 meq/1) 3)没有胆汁或盐混合物重新进入。表观能量消化率主要在结扎胆管(-31.6 p. 100)或从肠腔取出胆汁(-23 p. 100)后受到影响。这种减少主要是由于总脂质表观消化率(―53 p. 100胆管结扎术后;31.7 p. 100取胆后)。表观氮和来自碳水化合物消化率的能量不受影响。在有瘘管的猪中，十二指肠内引入盐混合物并没有改善下降的表观消化率。
