backgrounds: subclinical ketosis can cause greater economic loss due to a lack of clinical symptoms. objectives: the present study was aimed to design a chemical method for measuring serum ketone bodies in the affected subclinical cows. methods: acetoacetate concentrations were measured using a nitroprusside reaction and b-hydroxy butyric acid (bhba) which was oxidized to acetoacetate using nan...

The aim of this study was the effect pre-synchronization blood BHBA level on pregnancy rates sheep in non-breeding season. For purpose, 100 Merino/Merino crossbred ewe, aged 2-4 years, who have given one birth before, were used study. synchronization purposes, progesterone containing sponges 60 mg Medroxyprogesteron acetate (MPA) analogue, administered intravaginally for 14 days. (betahydroxybu...

Background: The Lori-Bakhtiari sheep breed is one of the most common native breed in the south-western parts of Iran. The peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. OBJECTIVES: This study was carried out to compare the serum concentrations of glucose, non-esterified f...

Acidosis is an important cause of mortality in severe falciparum malaria. Lactic acid is a major contributor to metabolic acidosis, but accounts for only one-quarter of the strong anion gap. Other unidentified organic acids have an independent strong prognostic significance for a fatal outcome. In this study, a simultaneous bio-analytical method for qualitative and quantitative assessment in pl...

Lizin ve metiyonin gerek büyüme gelişme gerekse süt verimi açısından sınırlayıcı etkiye sahip amino asitlerdir. İlk doğumunu yapan düveler bir taraftan laktasyona başlarken diğer hala çağındadırlar. Yapılan bu çalışmada ilk yapacak olan düvelerde gebeliğin son iki ayında ilave olarak rumen korumalı lizin verilmesinin bazı kan matabolizma parametreleri üzerine etkileri incelenmiştir. Çalışmada o...

This study aimed to estimate the changes in milk yield, fat, energy indicators [NEFA, BHBA, Dry MatterIntake (DMI) and Body Condition Score (BCS)] concentration of innate immune molecules (Haptoglobin: Hp,Serum Amyloid A: SAA, TLR-4, TNF-α, IL-1β, IL-6, IL-8), during transition period primiparous andmultiparous dual-purpose zebu (Deoni) cows. The blood sample was collected at weekly intervals p...

The objective of this study was to evaluate effects of a daily oral drench of Propylene Glycol (PG) on fertility in dairy cows experiencing seasonal heat stress. In treatment group, cows (n=9) were treated with drenching 250 ml propylene glycol once daily from 3 to 15 days post-partum following the morning milking. Another group of cows (n=9) was selected as untreated control. The serum beta-hy...

u çalışmada holştayn ırkı düvelerde yaşamın 9. ayından başlanarak gebeliğin belirlendiği zamana kadar rasyona rumen korumalı lizin ve metiyonin ilavesinin bazı kan metabolizma parametreleri üzerine etkileri incelenmiştir. Bu amaçla 40 adet sağlıklı 9 aylık yaşı doldurmuş (9-10 ay arası) düveler rastgele örnekleme metodu K (Kontrol) U (Uygulama) olmak üzere 2 gruba ayrılmıştır. Kontrol grubundak...
