To assess the roles of feeding behavior (eating and rumination) and systemic arterial pressure (SAP) on determination of the circadian rhythm of renal blood flow (RBF), 20 sheep fitted with ultrasonic flow-metering probes around both renal arteries and a submandibular balloon to monitor jaw movements (6 of them with a telemetry measurement system into the carotid artery for SAP recording), were...

Changes in progesterone (P), testosterone (T), estrone (E, ) and estradiol-1 7j3 (E2) in peripheral blood, ovary, corpora lutea (CL) and in the nonluteal portion of the ovary (NLO) were studied in the cyclic hamster by RIA. In addition, androstenedione (A) was measured, but only in serum. Serum P levels were the same on Days 1 (day of ovulation) and 2 at 0900 h (5 ng/ml), but declined markedly ...

Water movement in xylem vessel presents hydraulic system. The system may encounter embolism (cavitation) caused by environmental stresses. Tracer dyes are distributed within the and can be monitored sectioning tissue called dye infusion technique. current experiment determined optimal conditions for acid fuchsin technique to monitor water-conducting pathways shoots of sweet cherry peach trees. ...

Bu araştırma, Prunus mahaleb L. anacı üzerine aşılı 0900 Ziraat kiraz çeşidinde, bor ve çinko içerikli yaprak gübrelerinin bazı meyve kalite özellikleri etkilerini belirlemek amacıyla 2018 yılında Yeşilli (Mardin) ilçesindeki iki ayrı bahçesinde yürütülmüştür. Çalışmada; kontrol, 100 L suya 150 cc Maxifruit (1. uygulama), Fertileader® Oris (2. uygulama) + 50 Alpha (3. gübreleri kullanılarak, ta...

The present study was undertaken to investigate the impact of heat (thermal) stress and dietary antioxidant supplementation on the oxidative and physiological status of sheep. Twenty-four Merino × Poll Dorset crossbred ewes were housed in 1 of 2 climatic chambers (thermoneutral or heat stress) and offered either a control (10 IU vitamin E/kg DM and 0.24 mg Se/kg DM) or high antioxidant (100 IU ...

The time at pasture of dairy cows is often restricted in the context of extending the grazing season in autumn or at the end of winter. The objective of our study was to evaluate the effects of a restriction of time at pasture on milk production, herbage intake and feeding behaviour in dairy cows according to feeding regime. The four treatments consisted of 4 h or 8 h of time at pasture per day...

In an attempt to repair chondral lesions in a joint, different methods are under investigation that use human chondrocytes for transplantation. In our laboratory we have used the alginate system to study the effects of various growth factors and cytokines on human chondrocyte metabolism [1]. Evidence is accumulating that Insulin-like growth factor-I (IGF-I) may play a key role in maintaining th...

To determine whether non-fibrous carbohydrate (NFC) supplementation improves fiber digestibility and microbial protein synthesis, 18 Corriedale ewes with a fixed intake level (40 g dry matter (DM)/kg BW0.75) were assigned to three (n = 6) diets: F = 100% fresh temperate forage, FG = 70% forage + 30% barley grain and FGM = 70% forage + 15% barley grain + 15% molasses-based product (MBP, Kalori 3...

OBJECTIVE The methoxyindole pathway metabolite, melatonin (aMT), and the kynurenine pathway metabolites, kynurenic acid (KYNA), xanturenic acid (XA) and 3-hydroxyantranilic acid (3HANA) are anticonvulsants, whereas the kynurenine pathway metabolites, L-kynurenine (KYN) and 3-hydroxykynurenine (3HK), are proconvulsants. It is thought that alterations in the concentrations of these compounds may ...
