[The use of dried grape press cake in pig fattening].

In dried grape press cake the content of crude nutrients and ash, overall sugar, amino acids, alpha-tocopherol and gross energy was determined. In biological experiments with pigs (total of 109 animals) 10% of mixture A1 or SOL was replaced by the same amount of dried crushed grape press cake, without affecting negatively the weight gains and consumption of mixtures per unit of weight gain. Nutritional effects of grape press cake are a subject of discussion and comprise three factors: higher content of enrgy (fat and sugars) in mixtures containing press cake, anti-oxidation effect of press cake and the effect of tocopherols on the metabolism of basic nutrients.

[An electric dynamic katathermometer and the thermal environment in pig farrowing pens].

Temperature conditions were measured with an electric dynamic catathermometer (EDC) and thermometers in pig farrowing houses 13 and 90 cm above the floor of the central and side corridors, boxes for sows and in piglet pens, heated with electric infra-radiators (input 525 W). The heat flow density of the EDC sensor, characterizing the cooling properties of the environment, was higher near the floor, at the ends of stables, on the sides exposed to wind, and after turning on the fan. The thermal conditions in the farrowing houses were therefore highly variable. In the piglet pens the heat flow density was usually kept at a very low level, owing to the thermal radiation of the electric infra-radiators, with possible bad implications for production. However, these facts cannot be documented just by the current measurements of air temperature.

Regulation of bovine labor with a long-acting carba-analog of oxytocin: a preliminary report.

The long-acting oxytocin (OT) analog 1-desamino-1-monocarba-E12-Tyr(OMe)]-OT(dCOMOT) was given IV to 13 pregnant cows near to term, but not in actual labor. The animals were para 1 to 5. Of these cows, four were treated with 20 mg of dexamethoasone 48 hours before the peptide was injected; the remaining nine animals were given no other medication. The animals usually were given a single injection of 5 mg of dCOMOT into the jugular veiw (5 to 7 micrograms/kg of body weight). In those instances where delivery was not complete within six hours, a second injection of peptide was given. In all instances, the first injection initiated labor as judged by the behavior of both uterus and cow. In most instances, there was also intermittent spurting of colostrum from the udder over a six-hour period after injection. In the four cows treated first with dexamethasone, the mean duration of induced labor was 4.35 hours after dCOMOT injection. In the nine non-treated cows, the mean duration of induced labor was 14.25 hours. The difference between the two values was significant. For both groups separately, and all data together, there was a linear inverse relation between the size of the external ostium uteri at injection and the duration of labor after peptide injection. All calves were healthy with no signs of hypoxia and the dose rates used did not result in any instance of uterine tetany or tachyphylaxis.
