Abstract

North American bison (Bison bison) producers face many challenges, including the potential clinical and economics problems caused by trichostrongyle nematodes within their herds. Little is known about the prevalence, intensity, geographical distribution and clinical significance of these parasites...

Abstract

The efficacy of eprinomectin in an extended-release injection (ERI) formulation in the treatment of cattle harboring naturally acquired nematode populations (including inhibited nematodes) was evaluated. Five studies were conducted under a similar protocol in the USA, the UK, and in Germany. All...

Abstract

The effects of either ivermectin or fenbendazole therapy in 72 beef cattle in Louisiana, USA, was evaluated over a 13-month period. The cattle were divided into 4 groups which were assigned to separate pastures: (1) ivermectin (200 µg/kg sc) administered at weaning then at 4.5-6 week intervals; (2) ...

Abstract

A study was initiated to (1) determine species of gastrointestinal nematodes present in cattle in selected areas of Oregon, USA, (2) examine seasonal abundance of these nematodes as an indicator of periods of transmission, and (3) determine when developmental inhibition occurs in the major genera...

Abstract

Observations on faecal egg count (FEC) and nematode identification data were compiled to help determine the extent of nematode parasitism in cows and their nursing calves in various regions of the USA. Overall mean FEC values for cows in Utah, Louisiana, Nevada, Texas and California were 7 eggs per ...

Abstract

The efficacy of ivermectin on susceptible or resistant populations of H. contortus was determined in cattle and goats held in a barn in Texas, USA. Goats were each infected with 3000 infective, ivermectin-susceptible or -resistant H. contortus larvae on day 0 and reinfected with 2000 infective...

Abstract

A trial was made in Colorado, USA, in 1991 using 230 first-calf heifers with calves at an Eastern plains (EP) ranch and 489 cow/calf pairs at an intermountain (IM) ranch, to examine the effect of a spring deworming of beef cows on cow faecal egg counts, cow body condition score, reproductive...

Abstract

The effect on weaning weight of calves when beef cows and their calves were treated with fenbendazole was investigated in North Dakota, USA. Two calf crops in 4 different herds were studied over a 2-year period (1988-1989). Each herd was divided into 2 groups; group A was treated each spring (May...
