Publication Factors affecting colostrum quality and calf passive transfer levels in holstein cattle(Polska Akad Nauk, Inst Genetyki I Hodowli Zwierzat, 2019-01-01) Özlüer, Abdurrahman; Abdullahoğlu, Elif; Duru, Serdar; DURU, SERDAR; Filya, İsmail; FİLYA, İSMAİL; Veteriner Fakültesi; 0000-0001-5243-4458; I-9517-2017; AAH-2927-2021The aim of this study was to determine the quality of colostrum in Holstein cattle and factors affecting serum total protein and immunoglobulin levels of calves. In the study colostrum samples taken from 334 Holstein cows in the first milking and serum samples collected from 354 calves born to these cows were evaluated using a digital refractometer. The minimum, maximum, mean and standard error values were 14.4%, 40.6% and 27.9 +/- 0.2%, respectively, for the colostrum Brix and they were 19.7 mg/ml, 168.1 mg/ml and 95.9 +/- 1.4 m g/ml, respectively, for colostrum immunoglobulin. The same values were 3.9 g/dL, 10.9 g/dL and 6.5 +/- 0.1 g/dL, respectively, for the serum total protein and 2.2 mg/ml, 37.7 mg/ml and 13.6 +/- 0.3 mg/ml, respectively, for immunoglobulin. The share of the colostrum samples below Brix 22% was 8.2% and that of the samples with immunoglobulin levels below 50 mg/ml was 3%. The percentage share of calves with a scrum total protein level below 5.5 g/dL. was found to be 15%, while the percentage of the immunoglobulin levels below 10 mg/ml was found to be approximately 30%. Birth season, lactation number, birth type and body condition score were found to have significant effects on colostrum quality (P<0.05). The serum total protein and immunoglobulin levels of female calves born in spring-summer to cows in their 4th and successive lactation and consuming at least 3 L colostrum Brix 30% in the first feeding were higher than in the others. Colostrum quality of cows and serum characteristics of calves should be evaluated in dairy farms. This is especially important for farms where calf deaths are more prevalent. Because of varying absorption ability, it may be advisable to give Holstein calves 3 L colostrum including IgG with min. Brix 23% or min. 80 mg/ml in the first feeding.Publication Effect of garlic oil on lamb fattening performance, rumen fermentation and blood parameters(Mattioli, 2021-03-01) Canbolat, Önder; Kamalak, Adem; Kalkan, Hatice; Kara, Hüseyin; Filya, İsmail; CANBOLAT, ÖNDER; FİLYA, İSMAİL; Ziraat Fakültesi; Zootekni Bölümü; CJR-8926-2022; CQT-8475-2022The objective of this study was to determine the effects of garlic essential oil (GEO) on performance, ruminal fermentation and blood parameters of Kivircik lambs. Forty-eight 2.5-3 month old Kivircik male lambs were allocated into four treatment groups. Diets were supplemented with GEO at the 0.0, 0.4, 0.8 and 1.2 g/kg DM. The growth trial lasted for 63 days. The supplementation of GEO significantly decreased the total weight gain (TWG) and average daily weight gain (ADWG), whereas it has no effect on the final body weight (FBW) daily feed intake (DFI) and feed conversion ratio (FCR). The supplementation of GEO to the lamb diets had also a significant impact on rumen fermentation and blood parameters. The addition of GEO to the lamb diets increased non-esterified fatty acid production while supplementation significantly reduced the levels of glucose, urea, protein, triglyceride, insulin and cholesterol. It can be said that the decrease of glucose, urea, triglyceride, insulin and cholesterol is important in terms of animal health when the blood parameters are taken into consideration. As conclusion, GEO supplementation up to 0.8 g/kg DM can be recommended for growing lambs to manipulate rumen and blood parameters without compromising important growth parameters.
