Two experiments were carried out to investigate the capacities of pigs for bulky feeds. In Expt 1 fifteen pigs were offered, from 12 to 25 kg live weight, ad lib. access to one of five feeds which were made by progressively diluting a high-quality feed with wheat bran. Intake initially increased, and then declined, as the proportion of wheat bran was increased. The pigs became better able to ac...

For 1,442 Belgian Blue bulls performance-tested at the Centre de Sélection de la Race Blanc-Bleue Belge, nine traits were observed: height at withers at 7 mo, height at withers at 13 mo, weight at 7 mo, weight at 13 mo, average feed consumption of concentrates, average daily gain, average feed consumption of concentrates per average daily gain, average feed consumption of concentrates per mean ...

This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...

Introduction One of the major expenses in any fish culture operation is the cost of feeds for the fish, and the profitability of many operations is frequently tied to the cost of feed. Hatchery production of fish larvae most often requires the expensive production of live food (phytoplankton and zooplankton), because artificial diets are either not available, or are grossly inadequate. Artifici...

A TOTAL of 146 gilts were randomly assigned at estrus to one of the following flushing treatments: (1) control--2.27 kg of feed daily; (2) 1-day flush--2.27 kg of feed daily, except for a 24-hr. period of ad libitum feed intake during mating estrus; and (3) 14-day flush--2.27 kg of feed daily except for a 2-week period of ad l ibitum feed intake starting on day 7 of the estrous cycle. Average o...

Ninety-six crossbred sows and gilts were used to study the effect of yeast culture (Diamond V. Mills, Cedar Rapids, IA) on apparent nutrient digestibilities and reproductive performance from d 60 of gestation through d 21 of lactation. Sows were allotted to treatment groups based on parity and BW. Four dietary treatments were made by substituting 0, .5, 1.0, or 2.0% yeast culture for wheat midd...

Vampire bats belong to the Desmodontidae family. Three species live in tropical and sub-tropical America. The most important one is Desmodus rotundus a medium size bat (Figure 1). These bats feed on blood of vertebrates and are very adapted to this diet. They take nearly 15ml of blood per meal. They live in colonies in humid caves or in splits of trees. In the colony, they show strong social li...
