    Summary: In the pig production managment microclimate monitoring of largeor cooperative production facilities is gaining everyday farms in its important. During the period of one year researches havebeen accomplished on a large pig-breeding farm. By monitoringpiglets in the farrowing units an attempt was made toestablishthe interaction between some particularbioclimatefactors and the prevelance of gastrointestinal syndrome andpneumonia.We have establishe that lowtemperature in November anddecember (l7,5řC and l7,1 řC) low air speed (0,11 ms-1) and highrelative humidity (79% and 77%) resulted in high incidence oflosses due to the gastrointestinal syndrome (27 and 38 dead pigs)or pneumonia(58 and 68) dead pigs.

    Summary: Bioclimate studies were condusted in pre fattenining and fattening units of a large swine farm, located in the continental climate zone influenced by alpine climate. Bioclimate parameters (air temperature, air speed, relative and absolute humidity, and gasses CO2 and NH3) were monitored monthly during one year period.Minimal and average values were recorded. The managment and housing technology of triple crossbreed (swedish landracexYorkshirexGerman landrace) is briefly described.During the fattening period the pigs were fed with complete pre fattening and fattening mixtures. In the first part of monitoring the pigs were fed with liquid feed. In the second part of monitoring, after the reconstruction of the facilities, they were fed the IBO system equipment. The results of production of fattening pigs in the period from 1975 to 1984 are also presented (growth rate and feed conversion ,necessary slaughter, losses) as well as health after the reconstruction of the farm and eradication of swine dysentery.

    Summary: The immunologic response modifier Baypamun obtained from inactivated Parapos ovis (strain D1701) was tested in order to establish wheter or not it could 1) stimulate humoral/lacteal immunity in gilts, 2) enhance passively acquired colostral immunity in their sucklings, and 3) decrese losses due to the gastrointestinal syndrome (GIS) among these pigs during preweaning period.Ten parturient gilts were given i.m. 2 ml. of Baypamun solution 9,7, and 2 days before the anticipated farrowing.Two control groups comprising 10 parturient gilts or sows each received 2 mL of saline as a placebo.The immunological observations were performed in the dams before farrowing and in their offsprings(along with clinical,bacteriological, ambiental and production parameters) from birth to weaning. Baypamun treated gilts had significantly higher (P 0.05) serum levels of total proteins (TS) and immunoglobulins (Igs) than nontreated gilts. The serum levels of Igs and TP in pigs born to gilts injected with Baypamun were significantly higher 7 days (P 0.01) and 14 days (P 0.01;P 0.05) after farrowing, respectively, than those in both control groups. Pigs born to Baypamun treated gilts survived much better (8.6/9.5 or 9o.5% weaned pigs per litter) than the offspring from the control sows(7.9/9.9 or 79.8%) during the preweaning period. No losses due to the GIS were observed in principals. Fifty percent ( in litters of sows) or 83.3% (in litters of gilts) of total losses were diagnosed as the GIS among control pigs).

    Summary: The causes of losses of suckling pigs from a large swine farm investigated and classified on the basis of monthly pathomorphological examination in the period from June 1985 to May 1988. The most common losses in the preweaning period were due to stillbirth, overlaying/crushing, culling(technological waste), and disease among which gastrointestinal syndrome (GIS) was predominant. The other disease (pneumonia, edema disease, congenital abnoramalities) made a minor impact on the total mortality rate and were excluded from the study). An average of 29,4% of all losses were prepartiurent death ranging from 26.6% in Decembar to 32.2% in October.A similar average of 28.8% pigs died of crushing. The lovest incidence of crushing was also observed in December (25.8%); the higest ws recorded in Auguust (32.7%).Of total losses 14.1% were due to culling with the minimum in November (11.4%) and the maximum in December (18.5%). Of those pigs that died of GIS, the lowest occurencews recorded in October (14%) and the highest in November (24.7%), with an average of 18.9% for three-year-period of observation.By sistematicaly collecting data on current pathology during that period and applying computerassisted program for the third degree trend curve we calculated the tendency of the proportion of monitored categories of losses in the total loss of pigs. Based on the trend curve for empiric (observed) losses with the lowest aberrattion from those for theoretical (expected) losses we were able to predict the tendency of each category of losses on large swine farm for a period of another three years.However, the significant changes in housing, mamangment or technology of production, and outbreaks of disease should be considered before any firm conclusions are made.

    Summary: Although the existing vaccines for control of neonatal colibacilosis can be used to protect neonates via passive lacteal immunity, they are not suitable for protection against postweaning enterotoxigenic Escherichia coli (ETEC).Infections in swine because the pigs have been deprived of acces to pilus-specific antibodies from their dams.The existing vaccine are not suitable for active immunization of pigs after weaning , because they are injected parenteraly and stimulate the systemic, rather than the mucosal immunity. Oral vaccines stimulate active intestinal immunity resulting in local (and systemic production of secretory antibodies which are secreted into intestinal lumen. and provide protection against ETEC pilus antigens. The field trial was conducted in comercial (previously found to have high incidence of postweaning colibacillosis) in northwest Croatia during Decenber and January of 1991.A total of 132 crossbred 2-weeks-old pigs were randomly assigned to either principal(n=67 ) or control (n=65) group. The principals were fed a diet supplemented with Colimix, according to the instructions of the manufacturer, at 2 and 5 weeks of age.Clinical obsrvation and evidence of diarrhea were recorded daily, starting on the day of weaning(at 3weeks of age). The death due to diarrhea were recorded at necropsy and section and provided for bacteriuology. Body weight gain was checked twice within 3 weeks after vaccination.Blood sampling was performed at 6 weeks of age and IgG titers in serum were determed using ELISA. Ambietal factors ( air temperature, relative humidity , drafts, gasses as CO" and NH3) were monitored by Solomat 2000 (solomat, Every, France) every seven days after the first vaccination. It was concluded that Colimix vaccina feeding may provide control of postweaning E. coli diarrhea and reduction of setback in rapidly growing pigs.Furthmore, the assiciation of Colimix feeding with the better rates of weight gain may provide justification for recommendable vaccination of 2a-week-old pigs.

    Summary: Although the existing vaccines against porcine enterotoxigenic Escherichia coli (ETEC) infections can be used to protect neonatal pigs via passive lacteal immunity., they are not suitable for protection against postweaning ETEC infections in swine. Presumably because of the parenteral vaccination regimens used, protection depends largely on serum IgG, which is unlikely to reach the intestinal lumen in quantities sufficient to prevent ETEC diarrhea in weaned pigs. Oral vaccines that stimulate the mucosal immune system, resulting in local production of secretory antibodies against ETEC fimbrial antigens are needed to prevent intestinal colinazation and diarrhea in weaned pigs. Live ETE are effective fimbrial vaccines (1) , killed ETEC or isolated fimbriae are much less effective (2) . We have used a model for the for the induction of diarrhea in weaned (3 weeks-old-pigs , by F4+ enterotoxigenic E. coli strain MI823 in susceptible pigs.The model includes feeding a diet containig new E. coli bacterin, Colimix(Solvay Animal Health, Inc. , Mendota Heights, MN USA) consist of a mixture of killed bacteria expresing F4,F5, F6 and F41 fimbrial antigens. The objectives of the study reported here were to (1) determine whether Colimix in the diet effects the incidence or severity of diarrheal disease in the model, and to (2) evaluate whether the resistance to F4-mediated adhesion and/or Colimix- treatment correlate positively with rate of weight gain among market pigs. Diarrhea developed in F4-susceptble pigs in the control (1 of 5 pigs) and Colimix-treated/M1823-inoculated (4 of 7 pigs) groups, and 4 of the 4 affected principals died from complications resulting from diarrhea. None of the 8 F4-susceptible Colimix- treated noninoculated pigs developed diarrhea before 3 weeks of age.The F4 rezistent pigs from the control and colimix treated/M1823 inoculated groups gained weight significantly faster from 6 to 21 day after inoculation (P 0.05) difference in weight gain between susceptible and resistant Colimix treated non-inoculated pigs.The F4 susceptible pigs in the Colimix treated group gained weight significantly faster from 6 to 21 Day after inoculation than their susceptible counterparts in the control (P .001 and P 0.01,respectively) and colivalues for anti-F4 antibody in the intestinal secretions from pigs treated with Colimix or Colimix-treated /M1823-inoculated were much higher (P 0.01) than those from control pigs.

    Summary: The occurence of diarrheal disease due to certain enterotoxigenic strains of Escherichia coli (ETEC) immediately after weaning appears to involve immunological (1)and nutritional factors (2). Also, the stressful events accompanying weaning (loss of mothering, change of feed, changes in ambiental temperature and managment, and social interaction with pigs from other litters) have been associated with an increase of diarrhea(3,4). It is also possible that, at weaning, the gut becomes acutely susceptible to ETEC because it is no longer protected by lactogenic immunity.Weaning may trigger the proliferation of rota-virus and other enteric pathogens (5).The objectives of this study were to (1) determine the causes of pig mortality based on both clinical observations and necropsy findings, and to(2) correlate the incidence of losses resulting from gastrointestinal syndrome (GIS) or bronchopeumonia (BP) anmong weaned pigs with changes in air temperature and/or relative humidity in the rearing unit of the farm. A Positive was found between ambiental air temperature and frequency (mortality) of Bp (r=+0.42) or GIS (r=+0.49). Also, it was establisdhed that incidence of BP and GIS correlated positively with relative humidity (r=+0.36 and r=+0.17 respectively).

    Summary: Preweaning mortality is a significant cause of losses in swine industry, with rates of 11.3% to 22.3% having been reported in different countries. It is estimated that losses among suckling pigs in Croatia ranging from 10% to 25%.- Infectious diarrhea is the most common cause of mortality or sickness of neonatal pigs, and enterotoxigenic Escherichia coli(ETEC) was indentified to be the ethiologic agent in more than 50% of the cases submitted to diagnostic laboratories in this country. Several factors associate with farrowing and sucklking are thought to predispose to neonatal diarrhea.Changes in enviromental temperature feed and decrease of lactogenic immunity have resulted in increased incidence and duration of diarrhea after infection with ETEC. The study was conducted in one farrowing unit of a large intesive swine farm in Croatia during the period between January and October of 1989. Clinical observations were made daily and examination of pigs that died was limited to gross observation at necropsy..Each death was classified into a category based upon the ultimate cause of death.Ambietal conditions such as air temperature and relative humidity were monitored monthly using Solomat MPM 2000 (Solomatm Evry, France). The study was conducted in one farrowing unit of a large intesive swine farm in Croatia during the period between january and October of 1989. In the results in this study is very important there was a positive correlation between incidence (mortality) of GIS and changes in air tempertature. Such correlation was not established between mortality due to BP and changes in relative humidity. Both, relative humidity and air temeorature had no effect on mortality/rates recorded for GIS and BP, respectively. It was concluded that stressfull changes in air temperature may predispose to GIS by triggering the proliferation of pathogens(bacteria or viruses) that have been carried in the gut at subclinical levels during the suckling period.

    Summary: Although porcine necrotic enteritis (NE) caused by Clostridium perfrigens is known for almost fourty years (1), it is still not well elucidated a role of the contaminated feed for lactating sows in the incidence of the disease . The association between the diet for sows and the incidence of clostridial infection in suckling pigs has been reported earlier. The curent study has been undertaken to reveal the possible influence of C. perfrigens-contamination feed for sows on the incidence of NE among pigs on four large -scale farms in Slovenia and Bosnia and Hercegovina. As can be seen from the results, the losses due to NE the farm in Slovenian (1) ranged from 2-% to 15% regardless the abscens of feed contamination (November of 1990) or in the presence of high feed contamination (April- May of 1987; January of 1991) respectively. Since we monitored the incidence of NE in the Farm in Slovenia (1) from its begining in 1987(4), we have assumed that the infective material when once in the farm is very hard to eliminate, because it could be spread elsewhere from the feed. The incidence of NE in the farm 2 (Slovenia) was probably not connected with the feed contamination of feed which was negligible.A low contamination of feed in the Farms 3 and 4 (Bosnia and Hercegovina) and the absence of NE, indicate that the diet free of C. perfrigens could be important factor in the prevention of among suckling pigs.

    Summary: It is important to know properties decisive for the production and breeding performance swine industry. Characteristic of growth rate are one of them. Definition of growth correlate body - mass increase with time periods. In large swine population with homogenous breed and sex composition, it is important to know the possibilities of growth in all age groups of pigs to attain adjustable managment related to the expected production. This study was performed in large-scale swine farm with 6000 pigs production per year.According to rearing managment , Swedish Landrace xLarge Yorkshire sows were mated with germany landrace boars.In the frrowing unit ere 18 prepartiurent sows, which produced 137 weaned pigs. During rearing 23 pigs were lost.Weighing was pertformed in seven day intervals during the rearing period. All pigs were fed with commercialy available feed mixtures ad libidum.Without of results presentation we will give a short conclusion: (1) Live body weight gain of 80-day-old-pigs is proportionallly correspodent to weight of 24-day-old-pigs.(2) Obtained linear correlation is strong, positive and significant. (3) There is no significant correlation between sex and live body weight change.

    Summary: Understanding of monitoring systeme in swine pathology in large scale units in prefattening phase of production is possible by prognostic models based on observations during year period.Accomplisment of this task could be managed by computerised monitoring system cennected with recording system for pathomorpholocal findings in prefattening period. Prediction of most common losses among pigs will facilitate preventive and therapeutic measures assential for their control. In this investigation we have collected data on most common losses among prefattening pigs from professional team of the farm Veterinarians, which were later revised and analyzed by university pathologist. The frequence of losses due to gastroenteritis have shown in prefattening period an increase from February to June in 19887/89. year. The curves of pneumonia complex (the frequency of losses) during two investigated years were very similary except in 1988/89 when many cases of pneumonia occured post enzootic.The most common diseases included in GIS in prefattening swine were dysentery (47%) and salmonelosis (13%) and other losses were non -specific scours.The simalar situation was found in USA after consideration of swine dysentery .Esophagogastric ulcer or proventricular ulcer of gastric mucosa were present with 0.68% of GIS syndrome. The case pneumonia was similar in other countries, and it was the most important disease associated with M;ycoplasma hyopneumoniae.In the pneumonia was found in 5.7% of pigs which is less than twenty-four years ago when 80% of populations of prefattening swine were infected.

    Summary: Every intesive production requires the biggest possible profit, the best possible capacity of exploatation and a continous production. Pig production is not an exepmtion.It can be realized in large production units with a big number of animals, and a well organised proffesional service, which will select animals desirable breeding qualities. Along with the evolution of intesive pig production it has been noticed that a certain number of swine is culled or perish due to health disturbance.It is well known the biggest losses occur during suckling, and in the rearing period after weaning. The basic condition for sistematic monitoring of intesive production swine pathology is the accurate spoting of dead animals, as well as the establihment of the causes of death or culling.Such current pathology must be diagnosed by necropsy. It is presumable that on the ground of assembed data, concerning losses of swine caused by diseases, as well as dose not caused by illnes, the frequency and development tendency, regarding the structure, of particular losses, could be anticipated through a longer or shorter time period. The research was accomplished on the "Dubravica" farm near by Zagreb.During research, necropsies of perished suckling performed daily,during a period of one year.In the classification of losses we applied SNOVET systeme( Scientific National Organisation of Veterinary Terminoloy). The structure and volume of losses in farrowing units were as follows: crushed piglets 37.8%, culled piglets 7.6%, cachexia 1.9%, Starvation 8.0%. Beside the mentioned categories of losses, which were not caused by diseases, we also monitored those caused by illnes, as gastroenteritis which caused 41.4% of total losses and pneumonia with a remarkable lower rate of 3.3%.The season did not appear to influence the frequency per category of losses, during a six month period, except for those caused bay pneumonia with the highest rate during winter. The structure of losses in rearing units ws as follows: the highest rate oof losses was caused by gastroenteriti, 40.4% of total losses followed by losses caused by pneumonia 20.4%, and losses not caused by diseases although influenced by them, as cahexia with 18.7% of total losses.Theese cathegories are followed by losses such as limfadenitis and arthritis (2%). cardial synkopa(1.5%, canibalism (2.65%, and finally some sporadic illnes as stomach ulcer, liver distrophy,cystitis, intestinal meteorism, suffocation, liver or bladder rupture, with a total rate 7.8%. The distribution of pig losses during the entire year, di not seem to be considerably influenced by seasonal or climatic condition, exept for losses caused by pneumonia , with the highest rate during winter in the farrowing unit . the conclusion based on the our results are: -- that the approuch to the in our research, in order to quantitatively establish the most frequent causes of losses in intensive pig production, has shown to be justified; - that such an approuch, based on systematic health monitoring through necropsy diagnosis of vanished or culled pigs, offers to farm veterinarians a possibility for a more efficient pig health protection.
