    The effect of ?-carotene and vitamin E on metabolic profiles in nutritionally flushed sheep
    (South African Journal for Animal Sciences, 2022) Irmak, Mehmet; Kayri, Veysi; Tufan, Tuncay; Coşkun, Devran; Özcan, Cahit; Çelik, Özgür Yaşar; Denli, Muzaffer
    This study aimed to investigate the effects of β-carotene and vitamin E on serum biochemistry, body condition score, and the number of offspring in sheep during the flushing period. To this purpose, forty Romanov sheep 45 (±1 kg) body weight and 3 years of age were allocated into one of four experimental treatments with 10 replicates for 6 weeks: the control (only flushing), and three treatment groups injected intramuscularly with 1, 2, and 4 ml β-carotene + vitamin E in the third week of flushing, respectively. The 4-ml treatment of β-carotene + vitamin E evidently increased the follicle-stimulating hormone level. The 2-ml treatment of β-carotene + vitamin E increased the triglyceride concentration in the serum. Body condition score, offspring number, and biochemical parameters (cholesterol, phosphorus, calcium, magnesium, aspartate aminotransferase, beta hydroxyl butyric acid, total protein, and glucose) were not affected by any levels of β-carotene + vitamin E administration. These findings indicate the positive role of β-carotene + vitamin E administration on pregnancy rate and some blood parameters during flushing.

    EFFECTS OF MOLASSES, BARLEY, OAK TANNINS EXTRACTS AND PREVIOUSLY FERMENTED JUICE ADDITION ON SILAGE CHARACTERISTICS, IN VITRO ORGANIC MATTER DIGESTIBILITY AND METABOLISABLE ENERGY CONTENT OF GRASS SILAGE
    (Parlar Scientific Publications (P S P), 2020) Arslan, Cavit; Tufan, Tuncay; Avci, Mehmet; Kaplan, Oktay; Uyarlar, Cangir
    This study was carried out to evaluate molasses (M), barley (B), oak tannins extracts (OTE) or previously fermented juice (PFJ) addition as silage additives on nutrient contents, fermentation characteristics, in vitro organic matter digestibility (IVOMD), metabolisable energy (ME), methane (CH4) and ammonia N (NH3-N) production of grass silage. The M, B, OTE added 25 or 50 mg/kg, and PFJ 7.5 or 15 ml/kg to silage for compare to nothing added Control silage. Organic matter content was higher in Control silage than 50 g/kg M added silage. Addition of 25 and 50 g/kg OTE, or 15 ml/kg PFJ to silages decreased crude protein contents as compared to Control silage. Addition of 25 and 50 g/kg M or B, and 50 g/kg OTE decreased pH of silages as compared to 25 g/kg OTE and, 7.5 and 15 ml/kg PFJ added silages. Addition of 25 and 50 M or B, and 50 g/kg OTE increased lactic acid concentration as compared to other silages. Addition of 25 and 50 g/kg M increased IVOMD, CH4 and ME of silages as compared to other silages (except for GS + 50 g/kg B for ME). Generally, OTE or PFJ addition induced a decrease IVOMD, ME and CH4 production. Addition of 25 or 50 mg/kg OTE and 25 g/kg M increased NH3-N concentration as compared to 25 g/kg B added silage. In conclusion, the study showed that adding of M improved fermentative quality, OMD, and ME values of pasture grass silage, and the second most effective silage additive was B, but addition of OTE and PFJ have little effect on improving the silage quality as compared to Control silage.

    Japon bıldırcınlarının rasyonlarına çörek otu (Nigella sativa L.) tohumu veya çörek otu yağı ilavesinin besi performansı, karkas özellikleri ve bazı kan parametrelerine etkisi
    (Kafkas Üniversitesi Veteriner Fakültesi, 2015) Tufan, Tuncay; Arslan, Cavit; Sarı, Mehmet; Kaplan, Oktay
    Bu çalışma, bıldırcın rasyonlarına çörek otu tohumu ya da çörek otu yağı ilavesinin besi performansı, karkas özellikleri ve bazı kan parametrelerine etkisini belirlemek amacıyla yapıldı. Araştırmada, 180 adet bir günlük yaşta Japon bıldırcını civcivi kullanıldı. Civcivler 45 hayvandan oluşan 4 ana gruba, her ana grup ise 15 civcivden oluşan 3 alt gruba ayrıldı. Gruplardan birisi başlangıç (1-21. gün) ve büyütme (22-35. gün) dönemlerinde temel yemlerle beslendi (Kontrol). Diğer gruplar aynı yeme %0.1 oksitetrasiklin (Pozitif Kontrol: PK), %1 çörek otu tohumu (ÇOT) veya %0.1 çörek otu yağı (ÇOY) ilave edilerek beslendi. Deneme bitiminde her ana gruptan 15 bıldırcın kesilerek karkas verim özellikleri ve kan serum parametreleri belirlendi. Araştırma sonunda, PK ve ÇOT gruplarının canlı ağırlık ortalaması Kontrolden önemli derecede yüksek bulundu. Araştırma geneli dikkate alındığında ortalama canlı ağırlık artışı, yem tüketimi ve yemden yararlanma oranı bakımından gruplar arasında farklılık görülmedi. Karkas ağırlığı; Kontrol grubunda diğer tüm gruplardan önemli derecede düşük bulunurken, karkas randımanı, göğüs, but ve kanat oranları bakımından gruplar arasında farklılık oluşmadı. Serum kolesterol konsantrasyonu ÇOY grubunda Kontrol grubundan önemli derecede düşük tespit edilirken, Ca, P, VLDL, HDL, LDL, ALT, ALP, albumin, globulin ve total protein konsantrasyonu bakımından gruplar arasında farklılık görülmedi. Sonuç olarak; bıldırcın rasyonlarına %1 oranında çörek otu tohumu ilavesinin antibiyotik ilaveli grupta olduğu gibi canlı ağırlığı önemli derecede artırdığı, %0.1 oranında çörek otu yağı ilavesinin hipokolesterolemik etki gösterdiği tespit edilmiştir.
