Some preslaughter factors affecting the occurrence of bruising in sheep

The preslaughter handling and behaviour, and subsequent bruising was observed in 49 groups of sheep in a commercial slaughterhouse. A greater percentage of bruised carcases was found in lambs (71%) than in ewes (49%) (P less than 0.01). A greater percentage of severely bruised carcases was found in lambs from markets (20%) than in those direct from farms (12%) (P less than 0.05). Significant correlations were found between the occurrence of recent bruising and wool-pulls during unloading, riding by another sheep, and hits and squashes against structures at the slaughterhouse. However, even assuming that each potentially traumatic event observed in the slaughterhouse caused a bruise, only about one-quarter of the bruising could have been attributed to handling problems at the slaughterhouse. Eight-eight per cent of all bruises were estimated to have been caused within about 24 h of death, indicating that most bruising probably was caused by handling problems during loading on the farm, during transit and particularly at markets.     

The occurrence of phalaris staggers in sheep

Extract

Typical cases of the “staggers” syndrome associated with Phalaris tuberosa poisoning occurred at Invermay Research Station in October, 1954. It is being recorded because detailed records of pasture management and climatic conditions are available for the period when symptoms were seen, also the pasture composition of the Phalaris plot.

Enzootic pneumonia of sheep in New Zealand

Extract

Enzootic pneumonia of sheep is a specific condition confined to southern Otago and the Southland district and is commonly referred to as “Southland Pneumonia.” It has been recognized as a distinct clinical entity for many years in that area, heavy losses being reported in the Gore district of Southland in 1924.     

The occurrence of hypotaurine in ovarian follicle walls in sheep and in the Fallopian tube of sheep and other animals

Inhalt: In den Ovarien von Schafen kommen während des Brunstzyklus in den Folli-kelwandungen Hypotaurin und Inositol in Konzentrationen von 0–7 mg % bzw. 40 mg % vor. Hypotaurin wurde auβerdem in den Eileitern von Schaf, Pferd, Rind, Schwein und Kaninchen gefunden; in zwei Fällen gelang auch der Nachweis von Hypotaurin in der Fimbrienplatte der Hündin. Es wird die Hypothese aufgestellt, daβ bei mit Progesteron bebandelten Tieren das Fehlen von Hypotaurin möglicherweise die Entwicklung und den Transport der Eier ungünstig beeinfluβt.     

The occurrence of paradontal disease in sheep in relation to superphosphate topdressing,stocking rate and other related factors

Extract

The serological diagnosis of bovine leptospirosis, especially in areas where several serotypes of Leptospira are known to exist, would be greatly facilitated if a method could be used to screen sera for evidence of infection irrespective of the causal serotype. Once infection has been diagnosed, a more specific serological test could be employed to determine the serotype responsible. At least 4 serotypes of Leptospira are known to infect cattle in New Zealand, namely, pomona, hardjo, ccpenhageni and ballum.     

Experimental studies of chronic pneumonia of sheep

Strains of Mycoplasma ovipneumoniae and Pasteurella haemolytica isolated from sheep affected with chronic pneumonia were inoculated by endobronchial route to conventionally-reared and SPF (Specific Pathogen-Free) lambs. Changes resembling those of the naturally-occurring disease were produced in most lambs given the organisms in combination and in some given M. ovipneumoniae alone. Similar but less extensive changes were seen in SPF lambs and fewer animals were affected. Different strains of M. ovipneumoniae did not affect the extent of changes produced in SPF lambs. M. ovipneumoniae became established in the lungs of both types of sheep; P. haemolytica did so less readily.

It was concluded that chronic pneumonia may be reproduced in conventional animals by combined inoculation of M. ovipneumoniae and P. haemolytica. Age and status of immunity to mycoplasmas may account for the different responses of conventional and SPF lambs.
