Summary:
The distribution of rumen acidosis in high-yielding cows by season in the conditions
of farms in the Samarkand, Navoi, and Kashkadarya regions of our republic is presented.
Keywords:
acidosis, laminitis, lactic acidosis and UEC, abdominal fluid environment (pH),
chronic abdominal acidosis (CAA).
Relevance of the topic.
Diseases of imported purebred cattle, in particular digestive and
metabolic diseases, are one of the major obstacles to the implementation of agrarian reforms in
our republic and cause significant economic damage to livestock farming.
Currently, as a result of the high-concentrate ration of livestock farms in feeding high-yielding
cows and the lack of high-quality hay, large abdominal acidosis is observed on the basis of
diseases of the digestive system of livestock, including diseases of the foregut.
The aim of the study
is to develop a method for early diagnosis and treatment of rumen acidosis
in productive cows, as well as to improve group prevention methods.
Research object and methods.
Scientific research aimed at determining the prevalence of
abdominal acidosis in cows using dispensary methods was conducted at the Department of
Internal Non-Communicable Diseases of the Samarkand State University of Veterinary Medicine,
Animal Livestock and Biotechnology, at the farms "Agro-Bravo Chorvasi" in the Akdaryo district
of the Samarkand region, "Ochilov Makhmudjon Dalasi" in the Payarik district, "Yangi Asr" in
the Kyzyltepa district of the Navoi region, and "Omadli Zarnigor" in the Chirakchi district of the
Kashkadarya region.
Analysis of the results obtained.
The prevalence of ruminal acidosis in productive cows raised
on farms where scientific research is conducted was studied and analyzed during 2018-2021, and
it was observed that the indicators detected during this time were closely related to the seasons,
animal housing and feeding on the farm.
In order to study the seasonal prevalence of ruminal acidosis in cows, cows on specialized cattle
farms were examined on the principle of "similar pairs" at 8-9 months of the calving period and 1-
2, 4-5 and 7-8 months of the lactation period using a combined dispensary.
Gastric fluid and blood samples taken from cows were subjected to laboratory tests. The seasonal
distribution of peritoneal fluid was determined by measuring the pH, number, type, and functional
activity of ciliates in it, and the number of erythrocytes and leukocytes, hemoglobin, total protein,
glucose, and ketone bodies in blood samples.

Of the 110 Holstein cows raised at the Agro-Bravo Chorvasi farm in the Akdarya district of the
Samarkand region, 20% in the summer of 2018, 33.6% in the fall, 66.4% in the winter, and 58.2%
in the spring were diagnosed with large rumen acidosis. The prevalence of abdominal acidosis in
cows on this farm was also studied in subsequent years by season, and it was found that in 2019,
22.2% of 90 cows in the summer, 37.8% in the fall, 68.9% in the winter, and 62.2% in the spring,
respectively, in 2020, 22%, 36%, 72%, and 64.7% of 150 cows examined, respectively, in 2021,
25%, 40%, 70%, and 60% of 120 cows examined, respectively. (Table 1).

Conclusion
1. The incidence of rumen acidosis in productive cows is on average 18.9-72.9%, including 18.9-
28.8% in summer, 31.0-42.5% in autumn, 49.4-72.9% in winter and 42.9-63.1% in spring.
2. The main cause of rumen acidosis in productive cattle is feeding animals with a high-
concentrate diet based on the predominance of starch-rich grain feeds in 50-60% of cases, and
with low-nutrient diets in 40-50% of cases.
