Two adult Dorper ewes developed an oesophageal obstruction (choke) by consuming a pelleted ration. The history, clinical signs and method of treatment were recorded in each case. One case was treated surgically via rumenotomy and the other conservatively. Both ewes recovered uneventfully and no recurrence was observed. Reasons for the compaction of the pelleted ration in the oesophagus are disc...
Data from captive animals indicated that browsing (BR) ruminants have larger fecal particles-indicative of lesser chewing efficiency-than grazers (GR). To answer whether this reflects fundamental differences between the animal groups, or different reactions of basically similar organisms to diets fed in captivity, we compared mean fecal particle size (MPS) in a GR and a BR ruminant (aurox Bos p...
As a monogastric herbivore, the rabbit presents a unique feeding behaviour compared to other domestic animals, since he belongs to the Lagomorpha order (Leporidae family: rabbits and hares, Grassé and Dekeuser, 1955), and consequently possess a main specificity that is the caecotrophy. For recall (see details in chapter 1), the caecotrophy is a complete behaviour involving an excretion and an i...
We investigated aquaculture production of Asian tiger shrimp, whiteleg shrimp, giant river prawn, tilapia, and pangasius catfish in Bangladesh, China, Thailand, and Vietnam by using life cycle assessments (LCAs), with the purpose of evaluating the comparative eco-efficiency of producing different aquatic food products. Our starting hypothesis was that different production systems are associated...
Captive giraffe (Giraffa camelopardalis) mostly do not attain the longevity possible for this species and frequently have problems associated with low energy intake and fat storage mobilization. Abnormal tooth wear has been among the causes suggested as an underlying problem. This study utilizes a tooth wear scoring method ("mesowear") primarily used in paleobiology. This scoring method was app...
Phytochrome that was induced by red irradiation in vivo to pellet with subcellular material and that was released from the pellet by removal of divalent cations exhibited altered characteristics. Compared to phytochrome extracted in a soluble red-absorbing form from etiolated tissue, pelleted and released phytochrome, which was also assayed in the red-absorbing form even though pelleted in the ...
SMUTZ, E. R., E. H1RSCH AND H. L. JACOBS. Caloric compensation in hypothalamic obese rats. PHYSIOL. BEHAV. 14(3) 305-309, 1975. The present study explored the influence of pelleted diets on adjustment to caloric dilution in hypothalamic obese rats. Medial hypothalamic lesioned and normal rats were maintained on a high fat diet until the static stage of hyperphagia was reached, They were given t...
