Bodeninsektizidversuche zur Bekämpfung von Capnodis tenebrionis L. (Col., Buprestidae) im Kirschanbau Marokkos

Capnodis tenebrionis L. causes injury to stone fruit trees. Trials were conducted with organophosphate soil insecticides having less persistancy in soils than chlorinated hycrocarbon insecticides. Isofenphos proved very effective and can replace lindane.     

Effects of in ovo administration of L-carnitine on hatchability performance,glycogen status and insulin-like growth factor-1 of broiler chickens

1.?Eggs from a meat-type breeder flock (Ross) were used in two trials to study the effects of in ovo administration of L-carnitine (carnitine) on hatchability traits (hatchability percentage, embryo deaths, pipped with live or dead embryo), chick weight at hatch as an absolute value (CWT) or expressed as a percentage of egg weight (CWT%), hatching period, glycogen status (liver and pectoral muscle) and plasma insulin-like growth factor-1 (IGF-1) of hatched chicks were investigated. There were 9 treatments with three replicates of each. Treatments were non-injected control (negative control), or injection with sterilised saline (0?9%, positive control), or sterilised saline with carnitine at 25, 50, 100, 200, 300, 400, and 500 µg/egg.

2.?In ovo carnitine treatment increased CWT, CWT%, glycogen in the liver and pectoral muscle, glycogen index and plasma IGF-1 of hatched chicks, and did not influence hatchability traits and hatching period. The glycogen index of hatched chicks of the in ovo carnitine treatments with values (500 > 400 = 300 > 200) was higher than that of the control and in ovo carnitine at 25, 50, and 100 µg/egg treatments. The nature of response to carnitine was cubic for CWT and CWT%, and linear for glycogen in the liver and pectoral muscle, glycogen index of hatched chicks when the negative control or positive control treatment was used as base line.

3.?It was concluded that in ovo administration of carnitine at 25–500 µg/egg increased chick weight at hatch and IGF-1, and did not influence hatchability traits and hatching period of eggs. The linear relationship between in ovo administration of carnitine and glycogen status of hatched chicks indicated that increasing in ovo doses improved glycogen status of hatched chicks.     

Congenital hypotrichosis and partial anodontia in a crossbred beef calf

Clinical examination, skin biopsies, skull radiographs, and DNA analysis of a 2-day-old Red Angus-Charolais-Simmental cross bull calf confirmed the diagnosis of congenital hypotrichosis and anodontia defect (HAD), also called anhidrotic ectodermal dysplasia, which is a rare anomaly caused by a deletion in the bovine EDA gene on the X chromosome.     

Über die natürlichen krankheiten des goldafters,Euproctis chrysorrhoea L. (Lep., Lymantriidae) 1977 in bayern

Studie were made on the diseases in a population ofEuproctis chrysorrboea L. collected near Munich on vak trees. Three species of parasites found in the larvae were members of Protozoa: a)Pleistophora scbubergi Zwölfer which was the most prevalent (59%) and infected 34% L₃, 62% L₄ and 99% L₅; b) aNosema sp. (probablyNosema kova?evi?i Purrini & Weiser, 1975) which amounted to 1% in mixed infection with a nuclear-polyhedrosis Virus,Borrelina euproctis. This Virus alone (with a particle size of 2–2.5 microns) has been isolated from the 28 larvae (6%). Larvae usually died during the second (from nuclear-polyhedrosis) and third week (from microsporidia) with infection of intestinal-cavity (Pleistophora schubergi), fat-body (Nosema sp. probablyNosema kova?evi?i) and nuclei of adipose tissue (nuclear-polyhedrosis).     

Evaluation of an Interfragmentary Compression System for the Repair of Equine Femoral Capital Physeal Fractures

Femoral neck and proximal epiphyseal lengths were measured in 37 femurs from 19 cadaver foals that were 1 day to 12 months old to determine the applicability of a human interfragmentary compression system to equine femoral capital physeal fractures. Because components of the implant system are available only in fixed sizes, its use was possible in foals older than 5 weeks of age, but not in younger foals. The 135 degree angle plate conformed best to the equine femur. Femoral capital physeal fractures were created surgically and repaired with the implant system in three foals. Fracture stability was evident clinically and radiographically in all three foals until euthanasia at month 3. At necropsy, the treated femurs were 4, 8, and 27 mm shorter than their mates. Epiphyseal viability was verified in all three foals by tetracycline deposition and new appositional bone growth comparable with that in the contralateral control epiphyses. The treated capital physis was open but reduced in thickness in one foal, disorganized in one foal, and closed in one foal. Fixation by compression with the implant system resulted in stability sufficient for fracture healing and maintenance of epiphyseal viability, although it was associated with reduced longitudinal femoral growth.
