The aim of this research was to assess welfare indicators in different dairy cow management systems, determine the prevalence parasitic infections, and examine impact these infections on indicators. This study conducted 2024 45 Holstein-Friesian cows aged 2 6 years (first third lactation) Northern Serbia. Monitoring carried out tie stall, loose, pasture-based covering three production phases: late dry period, clinical puerperium, peak lactation. Cow evaluated using Welfare Quality® protocol,...
The dairy industry contributes significantly to anthropogenic methane emissions, which have an impact on global warming. This study aimed investigate the effects of a dietary inclusion brown seaweed Ascophyllum nodosum enteric emissions (EMEs), hematological and blood biochemical profiles, milk composition in cows. Eighteen Holstein cows were divided into three groups: CON (non-supplemented cows), BS50 (50 mL 10% A. nodosum), BS100 (100 nodosum). In each cow, measurements EME, dry matter...
Cortisol levels were measured in hair, blood and milk two different cattle breeds, kept under breeding conditions with genetic merit for production. Cows heifers of Holstein Busha breeds selected the study. concentration was determined by immunoassays. accumulation proximal (close to skin) distal (far from segments hair shaft. The influence colour washing prior extraction analysis also examined order establish additional factors that may have an impact on cortisol concentrations....
Cows in the peripartal period undergo changes thyroid hormones and are susceptible to lipomobilization and/or oxidative stress. The addition of chestnut tannins as polyphenolic compounds diet may improve feed efficiency prevent stress-related health disorders transition cows. However, relationship between tannin supplementation function, which plays an important role metabolic regulation, has not been investigated dairy This study was conducted investigate effects during close-up on status...
Abstract This study investigated the effects of dietary supplementation with chestnut tannins (CNT) on metabolic and antioxidant status prepartum cows along their colostrum quality. Pregnant multiparous Holstein were paired according to parity body condition score, assigned either a diet supplemented 20 g/d commercially available product containing (CNT, n=20) or an unsupplemented control (CON, for last 25±2 d pregnancy. Serum metabolite, insulin capacity indices measured in blood samples...
Introduction. Neonatal calves are often deficient in iron. Accumulating evidence indicates that iron status is associated with disease pathologies including diarrhea. Our objective was to examine the association between and gut function neonatal without a history of calf Materials Methods. Calves were divided into two groups based on their diarrhea; first group diarrheic (n=6) second non-diarrheic healthy (n=6). Blood samples (n=12) collected at day 12 age erythrogram determination...
Abstract Ruminant husbandry contributes to global methane (CH 4 ) emissions and beside its negative impact on the environment, enteric CH cause a loss of gross energy intake in cows. The study is aimed estimate emission metabolic status dairy cows via concentration profile as tool for analyzing CH4 production pattern. included eighteen whose was measured during three consecutive days periods: 2 hours before (P1), 2–4 (P2) 6–8 (P3) after morning feeding. Based emissions, were divided into two...
The aim of this study was to compare hair corticosteroid concentrations in ectoparasiticide-treated (n = 10) and non-treated 12) Holstein cows. Animals the treated group received cyfluthrin three times, on days 0, 28 56 experiment. Hair samples were collected from all cows 21, 42, 63, 84 experiment for determination cortisol corticosterone using immunoassays. respective averaged 209.78, 165.10, 260.78, 177.44 183.11 ng/g, while 172.58, 243.58, 309.73, 199.75 207.09 ng/g. These results...
In recent years, there have been numerous research activities related to the use of different herbal agents, especially those originating from chestnuts and garlic, as alternatives synthetic growth promoters like antibiotics. Garlic its active ingredients studied for their potential benefits, such improving feed intake, production performance, rumen fermentation, udder health. The aim our study was investigate influence garlic polysulfides, including diallyl polysulfide dipropyl polysulfide,...
Abstract The study aimed to determine the concentration of energy-related hormones in cow’s milk and consider them from a public health perspective. Fourteen Holstein cows were subjected blood sampling on following days lactation (DIL): 10, 30, 60, 90, 150, 180, 210, 250 280 hormones, fat protein content biochemical parameters. For same purpose, bulk-tank was sampled samples retail m ilk with 1.5% (CM 1.5 ) 3.2% 3.2 purchased. Milk insulin-like growth factor-1 (IGF-1) values significantly...
Pig stress syndrome (PSS) is an increasingly common disease. The disease the result of intensive selection for greater fleshiness, which resulted in a point mutation on 6th chromosome. inherited autosomal recessive, neuromuscular disorder fattening animals. Highly productive pig breeds are most susceptible to stress. appearance influenced by stressogenic factors, and passes preacute or acute course. Death occurs within 24 hours from moment action stressor, while dead body stiffness very...
Very intensive expansion of breeding capacities, early weaning piglets from inadequate microclimatic conditions, and nutrition in different production categories caused the appearance production-related technological diseases. Diseases digestive organs are a significant part pig pathology. Of enteric diseases, great importance belongs to dysentery. It is characterized by long-term germination large number vectors. Two diseases that were previously considered be atypical forms dysentery,...
Previous studies in the field of acid-base and oxidative status cows have mainly focused on transition period (three weeks before three after calving). The aim this study was to determine differences parameters electrolyte balance not only during period, but also at other stages production cycle. Holstein-Friesian were divided into four numerically equal groups (n = 6): early lactating (9?2 days milk - DIM), peak (50?5 late (170?10 DIM) dry (10?1 Venous blood samples taken from analyze...
An apathetic 14-year-old Hungarian Puli bitch was presented with a seven day history of vaginal discharge and reported ovariohysterectomy (OHE) conducted six years ago. Clinical examination showed elevated body temperature (39.5?C), enlarged abdomen, vulvar swelling. Despite OHE in the anamnesis, ultrasound abdomen demonstrated presence both ovaries large anechogenic zone resembling uterus. Vaginal cytologic hormonal analysis indicated that oestrus phase cycle. After laparotomy, intact an...
Mycopasmatic or enzootic pneumonia is the most common disease of respiratory system under in intensive pig production. It clinically manifested by coughing, a chronic inflammatory process lungs, high morbidity and relatively low percentage deaths. The infection can be transmitted horizontally vertically. Mycoplasma hyopneumoniae invades epithelial cells trachea, bronchi, bronchioles alveoli disrupts function ciliary body. Evagination occurs, so that cleansing airway mucosa mucociliary...
Hromost je najraniji ali i najvažniji klinički simptom oboljenja akropodijuma goveda. Prema literaturnim podacima u 90% slučajeva uzrok hromosti lokalizovan papcima, a 10% drugim anatomskim delovima ekstremiteta. Patološki proces 88% ispoljen na zadnjim ekstremitetima. Laminitis predstavlja aseptično zapaljenje korijuma papaka. Kao uzroci nastanka ovog oboljenja, pored mehaničkog preopterećenja papaka, navode se toksični uzroci. Duže davanje lako svarljive koncentrovane hrane, stvaranje...

Abstract This study aimed to evaluate glucose-induced insulin response in cows exposed different temperature-humidity index. Twenty early lactating Holstein-Friesian were divided into 2 equal groups based on season, as summer (SU) and spring (SP). SP not heat stress, while SU moderate or severe stress. Milk production was recorded daily. Starting from day 30 of lactation, intravenous glucose tolerance test (IVGTT) carried out three times at 30-day intervals. Blood samples taken before...
