Publication Effects of exogenous amylase in transition dairy cows fed low-starch diets: 2. total tract digestibility and blood urea nitrogen(Kafkas Univ, Veteriner Fakultesi Dergisi, 2019-09-01) Shaver, Randy Duncan; Gençoğlu, Hıdır; GENÇOĞLU, HIDIR; Kara, Cağdaş; KARA, ÇAĞDAŞ; Biricik, Hakan; BİRİCİK, HAKAN; Efil, Mukaddes Merve; Türkmen, İbrahim İsmet; TÜRKMEN, İBRAHİM İSMET; DENİZ, GÜLAY; Kovanlıkaya, Arda; Kıvanç, Recep Tolga; Yıldırım, Ramazan; Bursa Uludağ Üniversitesi/Veteriner Fakültesi; 0000-0001-7051-1349; 0000-0001-5077-5689; AAH-4311-2021; AAH-4032-2021; HJZ-4775-2023The objective of this trial was to determine the effect of exogenous amylase during the transition period on total tract digestibility, rumen pH and blood urea nitrogen in lactating dairy cows. The effect of exogenous dietary amylase supplementation on lactation diets with low starch concentration (19.5% of dry matter) and dry period diets with moderate starch concentration was evaluated (15.5% of dry matter). A total of 30 multiparus Holstein cows were randomly assigned to two groups with amylase (n=15) or control (n=15). Three cows from each group were randomly selected and ruminally cannulated for digestibility trials. The research was conducted starting at 21 d prepartum until 84 d postpartum. Digestibility of dry matter, organic matter, neutral detergent fiber, starch, and crude protein remained unaffected by treatment in postpartum. Average pre- and postpartum rumen pH concentrations were 6.25 and 6.15, respectively, and did not differ between treatments. Blood urea nitrogen (BUN) concentrations were lower in cows fed amylase supplemented diet compared to those fed diet without amylase in both pre- and postpartum periods (P<0.001). In conclusion, the dietary supplementation of amylase did may not affect the digestibility of nutrients, however, it may decrease the BUN concentration in pre- and postpartum period for cows fed amylase. Therefore, it may offer potential for improving nitrogen efficiency in dairy cows.Publication Butaphosphan and cyanocobalamin treatment of pregnant ewes: Metabolic effects and potential prophylactic effect for pregnancy toxaemia(Elsevier, 2015-04-01) Temizel, Ethem Mutlu; Batmaz, Hasan; Keskin, Abdülkadir; Orman, Abdülkadir; Gençoğlu, Hıdır; Çatık, Serkan; Topal, Onur; TEMİZEL, ETHEM MUTLU; BATMAZ, HASAN; KESKİN, ABDULKADİR; ORMAN, ABDÜLKADİR; GENÇOĞLU, HIDIR; Çatık, Serkan; TOPAL, ONUR; Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı; 0000-0001-9138-4422; 0000-0002-1933-7354; 0000-0003-1991-8957; HJZ-4775-2023; AAH-1712-2021; AAH-3831-2021; AAG-9134-2021; S-8278-2017; ECV-4083-2022; CHM-0716-2022The effect of administration of butaphosphan and cyanocobalamin on the prophylaxis of pregnancy toxaemia in ewe was investigated. Moreover, the effects of these compounds on body weight gain and biochemical metabolism of pregnant ewe was assessed. A total of 59 pregnant Kivircik crossbred ewes were used in this study. Group I (n: 15) was administered butaphosphan and cyanocobalamin three times before delivery at 1-week intervals. Group II (n: 15) was administered butaphosphan and cyanocobalamin three times before delivery at 3-day intervals. Group III (n: 15) was administered 0.9% NaCl three times before delivery at 1-week intervals. Group IV (n: 14) was administered 0.9%NaCI three times before delivery at 3-day intervals. Six blood samples Were taken from each ewe four times before delivery and two times after delivery. Haematological and biochemical analyses were performed.The levels of BHB and NEFA in groups administered butaphosphan and cyanocobalamin were noticeably lower but there were no statistically significance. Elevated BHB (>0.8 mmol/L), subclinical pregnancies toxaemia were identified in 56.66% in test groups and 72.41% in control groups in all ewes and this was higher in the ewes bearing multiple pregnancies 71.42 in test groups and 82.35% in control groups. Subclinical pregnancy toxaemia in pregnant ewes with twins or triplets is lower than the levels for the control groups, despite the greater lamb counts and weights of the ewes in test groups.Based on our results, it was concluded that the butaphosphan and cyanocobalamin combination could be used as an alternative treatment for the prevention of pregnancy toxaemia.

Twenty-four kids (44 days of age) were allotted to a control (CG) or an experimental (EG) group. Each group consisted of 12 kids. Each kid in EG was supplemented with 0.8 and 1.6 g/d of oligofructose-enriched inulin from day 1 to 5 and from day 6 to 15, respectively. Liquid oligofructose-enriched inulin supplementation did not affect faecal score and pH (P > 0.05). Faecal acetate, propionate and total SCFA concentrations did not differ (P > 0.05) between CG and EG, whereas faecal butyrate concentration was higher (P< 0.05) in kids supplemented with liquid oligofructose-enriched inulin. Due to trophic and antiinflammatory effects of butyrate, we hypothesize that oligofructose-enriched inulin supplementation may be useful to help tissue repair and regeneration, particularly during an intestinal infection. Faecal Lactobacillus, Bifidobacterium and Clostridium perfringens concentrations were not affected by oligofructose-enriched inulin supplementation (P > 0.05). Daily dose of oligofructose-enriched inulin tended to increase serum glucose concentrations (P < 0.09, P < 0.08). Serum urea and albumin concentrations were similar between groups (P > 0.05). Serum total protein and globulin levels were lower in EG compared with CG (P < 0.05). During the experimental period lasting for 15 days, there were no differences in growth performance parameters between groups (P > 0.05).
