Rintal 2.4% premix (Bayer) in single dose 7.5 mg of active substance on kg body weight was given to the calves of red and fallow deer. Effectiveness of deworming against nematodes from family Trichostrongylidae was 85.2% in red and 97.8% in fallow deer. Against namatodes from genus Trichocephalus the effectiveness was higher extending in red deer 98.1%, and in fallow deer 99.5%. Anthelmintic was not effective against nematodes Varestrongylus sagittatus and Elaphostrongylus cervi.
The PSE (pale, soft, exudative) and DFD (dark, firm, dry) syndromes were determined in 200 pigs and 201 slaughter cattle originated from the Lublin region. There were estimated pH1, pH24 and R index; besides, there were calculated a correlation between the pH1 measurements and R index and the size of carcasses. Qualitative PSE and DFD deviations were found in 133 pigs, i.e. in 66.5 per cent of the animals under study; in 61.5 per cent there were found distinct or partial PSE changes, while in 5 per cent the lesions of the DFD type. The changes of this type were also observed in 42.5 per cent of cattle, in 34 per cent the lesions were of the PSE type and in 8.5 per cent of the DFD type. The highest susceptibility to myopathy concerned m. semitendinosus, then m. semimembranosus and m. longissimus p. lumborum. In cattle myopathy was stated most often in m. psoas major and then in m. longissimus p. lumborum in which the DFD syndrome took place in most cases. There was found a significant correlation between pH1 and the size of carcasses.
To increase the possibility of choice anthelminth drugs for geese the efficacy of anthelmintic preparates used in fossorial birds to control geese helminthiases was examined. The examinations were performed on 2410 geese from the reproductive herds in 8 experimental groups. The intensity and extensiveness of parasitic invasion was evaluated by the Mc Master method of the examinations of feces. The birds were treated in autumn (November-December), e.g. one month before the predicted egg laying period. The following drugs were applied: group I—III, Bantminth 50 and 25 mg/kg of body weight once, 12.5 mg/kg twice, every day; group IV, Systamex 40 mg/kg; group V, Fenbesan 5 mg/kg, twice every day; group VI, Ivomec, injection subcutaneous 200 (µg/kg, group VII, Nilverm 50 mg/kg; Levamisole 15 mg/kg. The highest efficacy (100%) in the control of amidostomosis revealed Ivomec used in subcutaneous injection, then Banminth used as food additive: 95.3% at a dose of 50 mg/kg, 94.6% at a dose of 25 mg/kg, Systamex 91.9%, Banminth 88.4% used at a dose 12.5 mg/kg twice, Levamisole 86.7%, Nilverm 86.3% and Fenbesan 80.0%.
The experiment have been done in the groups of weaners naturally infested by Oesophagostomum dentatum (E.i.= 78.3 — 100%) and Ascaris suum (E.i. = 20.8 — 39.1%). Group I formed the untreated animals, group II — animals treated with Banminth at a dose of 10 mg/kg and group III — animals treated with Retinal at a dose of 10 mg/kg, twice at 5 day intervals. The animals were slaughtered at a weight 105 kg. The following parameters were determined: daily body weight gains, feed consumption per 1 kg of body weight, carcase yield, mean thickness of lard, physicochemical properties of meat, dry weight, content of fat, level of pH, water holding capacity, colour. It was found that dehelminthization of weaners at a half of fattening increases body weight and lowers feed consumption per 1 kg of body gain. The carcases of dehelminthized weaners characterise a higher body weight, higher carcase yield and better meat quality. Percentage of dry weight in the m. longissimus dorsi was comparable in the all examined groups, but the content of fat as well as the thickness of lard was higher in the animals from the experimental groups. The highes value of pH was noted in controls, the lowest in group III. No statistical differences were found in colour and water holding capacity between the three groups. Out of the anthelminthics used better course of fattening and meat quality was found in animals treated with Banminth.

Odrobaczanie danieli Fenbesanem w hodowli fermowej

Post mortem examination of 8 fallow deer before and 7 after deworming with Fenbesan in dose 7.5 mg/kg body weight during three following days administrated per os, showed unaequal sensibility of different species of gastrointestinal nematodes on this medicament. Especialy resistant to this drug were nematodes Ostertagia drozdzi and O. leptospicularis, and their percentage index of invasion intensity increased considerably after deworming. It can be a beginning of drug resistance. It is necessary to use different drugs to avoid it.
Bisexual gland hermaphroditism was diagnosed in the sea gull by a macroscopic post-mortem examination. The reproductive tract of the bird was composed of two testicles and two excretory ducts of the testicles joined to the ovary, as well as of a left ovary and oviduct. The bird showed partly male and partly female external sexual characteristics.
