The Thai Journal of Veterinary Medicine
The vaccination program for controlling Infectious bursal disease (IBD) was complicated due to high maternal antibody in day old chick. Therefore, our study was performed in young layer chickens with high maternal antibody as commonly seen in our country. The objective of this study was to determine the protective efficacy of immune complex IBD vaccines against very virulent infectious bursal disease virus (vvIBDV) challenge in commercial layer chickens. As immune complex vaccine A was recommended in layers by the company, the first aim of the study was to compare immune complex vaccine A (group 1) and B (group 3). The …

Rectal, faecal samples from 14 sheep were collected 3 times a day (morning, noon and evening) and examined for nematode eggs by the formalin-ether, sedimentation technique and the Brine floatation technique. The faecal egg counts were done by using the Stoll’s dilution, egg counting technique. The sheep were injected with ivermectin (Ivomec®) (0.2 mg/kg) subcutaneously. Three weeks later, faecal samples were collected and examined to determine the outcome of the treatment. It was found that strongyles and Trichuris ovis eggs were absent. It was concluded that Ivomec® showed good efficacy for the treatment of some gastrointestinal nematodes in this study …

Nine hundred and sixty day-old chicks of both sexes were divided into 24 groups of 40 birds each and fed for 42 days. Diets were prepared and fed over two phases (1-21 and 22-42 days of age). They were calculated to be deficient either in methionine and sulfur amino acids (negative control diet) or supplemented with 0.24% DL-Methionine (DL-M) or 0.37% Methionine Hydroxy Analogue (MHA). Weight gain and feed intake were calculated so that an evaluation of the efficacy of the 2 sources of methionine could be made. A significant response (P<0.05) in the average weight gain over negative controls (0.55+0.01 kg/bird) was found for DL-M supplemented diets (0.59± 0.01 kg/bird) in phase I, whereas MHA (0.57±0.01kg/bird) did not show any improvement. The feed conversion ratio of DL-M (1.80±0.03) and MHA (1.82±0.04) was significantly different to the negative control (1.93±0.03). There were no significant differences in all performances during phase II. The overall results showed that broilers fed with 0.24% DL-Methionine or 0.37% Methionine Hydroxy Analogue fortified rations showed the same growth rates. It may be concluded that MHA was 65% as efficient as DL-methionine in broiler chicks during the 1-21 day old period of their lives.
