A total of 11400 one-day-old chicks were randomly allocated to five dietary treatments with twelve replicates and were fed starter diets including either recommended (control treatment, T1) or a 6.25% lower level of both Ca and NPP according to breeder’s recommendations during starter period (SP). After SP, control treatment (T1) continued to be provided through diets containing 0.87 and 0.78 % Ca for grower (GP) and finisher periods (FP), respectively, while 6.25 % reduced group was divided into 4 dietary treatments regarding extent of decrease in Ca and NPP levels and provided by diets containing 0.79;0.65 (T2), 0.79;0.60 (T3), 0.75;0.65 (T4), and 0.75;0.60 (T5) % Ca for GP and FP, respectively. After SP, moderate and even substantial reduction of Ca and NPP significantly decreased feed intake (FI) (quadratic, P<0.05), but obtained similar body weight gain (BWG) and FCR compared to the control (P>0.05). On the other hand, reduced dietary Ca through T1 to T5 significantly decreased the total Ca and NPP intake of broilers (linear and quadratic, P<0.01), and accompanied to significant linear and quadratic relationship between Ca intake and FCR and BWG respectively. It can be concluded that reducing Ca level down to 0.75 and 0.60 % in grower and finisher phase, respectively are possible without compromising the growth performance and bone mineralization of modern broilers.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135942817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their use extends to pest control as well. Products used worldwide to protect pets are in liquid form and comprise spot-ons, shampoos, and spray. Close attention should be paid to proper usage of such insecticides in pets, particularly in cats. As already indicated by many studies, accidental or improper usage of such products can trigger severe health problems even proving fatal in cats. The objective of the current paper is to undertake a retrospective study of a total number of 47 cases suffering from pyrethroid intoxication in cats across several clinics in Tirana, Albania during the period 2016-2020. Records from the veterinary clinics were closely scrutinized with only specific cases of pyrethroid intoxication being included for the purposes of this study. The main clinical signs which were noticed in 47 cats included symptoms such as tremor/muscle fasciculation (37 cats; 76.6%), seizures (18; 38.3%), hyperaesthesia (19; 40.43%), ptyalism (13; 27.66%), ataxia (11; 23.4%), mydriasis (10; 21.28%). Out of 47 cases, 7 or 14.9 % of the treated cats did not survive. The outcome was solid after rapid interventions in 31 (65.96%) cats with the exception of 2 cats which did not survive dispide receiving treatment. Whereas as many as 16 (34.04%) of cats, having being taken late to the clinics, survived upon receiving treatment, while as few as 5 cats (31.25%) died. Awareness campaign targeting pet owners, owner education, appropriate product labelling and consultations with veterinarians may help eliminate this problem in the future.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135942825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Primarily, the genomic DNA was isolated from blood samples by the phenol/chloroform method. The genomic analyses were performed on a total of 160 Karacabey Merino (KM) sheep (n=80) and Kivircik (n=80). The PCR-RFLP method was used to determine the genotype of the SNPs. Deviation from Hardy–Weinberg equilibrium (HWE) and population genetic assays such as observed (Ho) and expected (He) heterozygosities, effective allele numbers (Ne), and the polymorphism information content (PIC) were calculated for each gene in the population. As a result, there was no deviation from HWE was determined except SCD and PROP1 gene in KM. The most frequent genotypes were found AA (66,25% and 87,50%) for AA-NAT gene, CC (93,75% and 91,25%) for SCD gene and CC genotype (70,00% and 56,25%) for PROP1 gene in KM and Kivircik sheep. All breeds were detected monomorphic in terms of the IGFBP3 gene. In conclusion, the other regions of the IGFBP3 gene which were determined as monomorphic in the studied flock could be researched.

Fecal coliforms, such as E. coli, are more specific indicators of fecal pollution. A fecal contamination detection can be performed not just in drinking water, but also in the environment. As a result of improved detection methods for E. coli, drinking water is becoming more reliable as a result of the use of E. coli as an indicator of fecal pollution. Drinking water contamination by feces is currently best detected by E. coli. Accordingly, temperate environments are more likely to have fecal coliforms than tropical environments, human and animal feces have high levels of E. coli in comparison to other fecal coliforms, and E. coli detection methods are more affordable, fast, sensitive, specific, and easy to use than other fecal coliforms.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135943708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was designed to determine the effects of varying pre- and postpartum DCAD diets on serum total calcium, ionized calcium, blood and ruminal fluid metabolites, and milk production in prepartum and postpartum Holstein cows. Fifty-four multiparous dry Holstein cows n= 54, were enrolled in a completely randomized block experimental design at 29 days prior to expected parturition through 86 days in milk. A 3 x 2 factorial arrangement of treatments was utilized. Three DCAD levels were fed precalving (0, -120 and -200 mEq/kg DM), n=18 cows per treatment and two DCAD levels were fed post calving (+200 and +400 mEq/kg DM), n=27 cows per treatment. Prepartum urine pH was lower for cows fed -200 DCAD compared with those fed -120 or 0 DCAD. Postpartum urine pH was higher for cows fed +400 mEq/kg compared to cows fed +200 mEq/kg DCAD. Prepartum serum total calcium, ionized calcium, and hydroxyproline was highest for cows fed -200 DCAD compared to those fed -120 and 0 DCAD. Parathyroid hormone was highest for cows fed 0 DCAD compared to those fed -120 and -200 DCAD. Prepartum dry matter intake (DMI) was lower for -200 and -120 DCAD compared with 0 DCAD. Postpartum DMI was not different among treatments. Pre- and postpartum DCAD treatments did not affect total milk yield or milk fat, percentage of milk protein not affected by different pre-and postpartum DCAD levels. Prepartum anionic diets lowered urine pH and parathyroid hormone and raised serum hydroxyproline, resulting in improved Ca availability after parturition. Postpartum blood metabolites were unaffected in cows given positive DCAD (+200 and +400 mEq/kg DM). Calves born to cows fed low DCAD had no change in calf bieth weight. Colostrum amount and IgG concentrations were unaffected by treatments. No effects of pre-or postpartum DCAD treatments were observed for milk yield and fat-corrected milk. Feeding prepartum an acidogenic diet improved postpartum Ca status in multiparous Holstein cows.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":"867 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135943843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental treatments were; 1: control, 2: thyme extract (2 kg/ton), 3: organic acid (3 kg/ton), 4: probiotics (50 g/ton) and 5: prebiotics (2 kg/ton) with normal and reduced protein levels (10% lower than usual). At d 42, two chicks per replicate were randomly chosen, slaughtered and carcass percentage and carcass components percentage including a thigh, breast, liver, heart, gizzard, spleen, bursa of fabricius, abdominal fat, and intestine were determined for live weight. The results showed that using a diet with a normal level of crude protein compared to a diet with a level of crude protein lower than usual, increased the percentage of spleen and heart of chickens (P<0.05). It seems that there is a close relationship between the percentage of fat in the abdominal cavity and the ratio of energy to protein in the diet. Also, there were no significant differences between treatments and their interactions about pH content of ileum of broilers (P > 0.05). Besides, the bacterial population of ileum of treated broilers had different behavior. The ileum bacteria improved with probiotic addition and it was predictable because of beneficial bacteria inclusion to diet. Comparing the means for litter traits, no significant differences were observed between the experimental treatments with each other and with the control group (P>0.05).

In recent years, botanicals have been reported as potential alternatives to anticoccidials since they are effective against protozoa, arthropods, and helminths. In this study, different doses of dried pomegranate fruit (Punica granatum L.) were evaluated for their effectiveness in reducing the number of oocysts in domestic cats and their antioxidant properties. Under in vivo conditions, 24 six-month-old domestic cats of both genders naturally infected with Cytoisospora felis were tested. Four equal groups of infected cats were formed. Six cats made up each group. The control group (C) was on a basal diet, and one group received the chemical coccidiostat robenidine (CR), supplemented in the amount of 0.5%. Two levels of whole dried pomegranate fruit as a natural antioxidant were applied in a concentration of 0.5% (P1) and 1.0% (P2) on top of the basic diet. With the McMaster technique, oocysts number and eggs per gram of feces were determined. From each cat, 6 per group, blood samples were taken from a jugular vein at the end of the experimental period to investigate the influence of dried pomegranate fruit on blood enzymatic activity and lipid oxidation. In conclusion, supplementing cats' diets with dried pomegranate fruit reduced the number of oocysts per gram of feces significantly, but it is important to carry out further and more detailed studies to prove the anticoccidial and antioxidant properties of dried pomegranate fruit in cats' diets.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135942822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to present the clinical, laboratory and surgical findings as well as the postoperative healing progress and therapy of these five cases. All cows showed a loss of appetite and were dehydrated, with a marked drop in milk yield. The rumen motility was severely reduced and an untypical tympanic resonance or ping and a splashing sound were present at the right flank at auscultation. All the cows had only a small amount of faeces. All animals had hypochloraemic metabolic alkalosis and most of them hyperlactatemia. Two of the cows were hypokalaemic. Hyperbilirubinaemia was revealed in all cows. Four of the cows had an increased haematocrit level. A standing right flank laparotomy was performed in all cows. A common surgical finding was the severely dilated, dorsally dislocated and twisted sigmoid flexure of the duodenum, and the empty descending duodenum. The abomasum of all cows was dilated, but not displaced. An enlarged gall bladder was found in four animals. The duodenal sigmoid loop was manually untwisted, followed by promoting gas and ingesta flow aborally in the descending duodenum. Omentopexy was performed in each cow. No cow had had any history of omentopexy or other abdominal surgery. All cows received intravenous fluid therapy after the surgery.

Poultry ration and food additives are essential in the regulation of reproductive activity. Phytase is a supplement frequently added to laying hen diets to increase phosphorus (P) utilization. The aim of this study was to reveal the effects of a newly isolated microbial phytase together with different concentrations of calcium (Ca2+) and available phosphorus (AP) on ovarian FSHR and LHR expressions. For this purpose, 90 Lohmann LSL-White layers were first divided into three main diet groups (standard Ca2+ and AP, standard Ca2+ and low AP, low Ca2+ and AP) and then into three subgroups (no-phytase, commercial phytase, and microbial phytase). At the end of the experiment, all chickens were slaughtered and ovarian tissues were fixed in formalin. Routine avidin-biotin complex immunohistochemistry was performed using anti-FSHR and anti-LHR primary antibodies. Immunohistochemically, FSHR and LHR were expressed in granulosa/theca cells, oocytes, interstitial cells, and vitellus. While the expression intensity of the receptors increased in the microbial phytase-treated groups, the strongest expression was obtained in the granulosa/theca cells and oocytes in the standard Ca and low AP group. In conclusion, we suggest that the addition of newly isolated microbial phytase to diets of laying hens and feeding standard Ca and low AP may have positive effects on reproductive performance by increasing the FSHR and LHR expression in ovaries.","PeriodicalId":17314,"journal":{"name":"Journal of the Hellenic Veterinary Medical Society","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135943847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
