Süt ineklerinde 2-Hydroxy-4-(methylthio) butanoik asit izopropil esteri'nin süt verimi ve kompozisyonu üzerine etkileri
Öz
Bu çalışmada süt sığırlarında metiyonin kaynağı olarak 2-Hydroxy-4-(methylthio) butanoik asit izopropil esteri (HMBi)' nin süt verimi ve kompozisyonu üzerine olan etkileri incelenmiştir. Ankara’nın Kızılcahamam ilçesinde bulunan Per çiftliğinde yürütülen çalışma 8 hafta sürdürülmüştür. Bu amaçla toplam 30 adet süt ineği, her birinde 10’ar inek bulunan birbirine benzer 3 gruba ayrılmıştır. Kontrol grubu olarak beslenen birinci gruptaki ineklerin yemlerine ilave bir metiyonin kaynağı eklenmemiştir. Pozitif kontrol grubu olarak beslenen ikinci grubun yemine, inek başına günlük 330 g, metiyonin sağlamak için mısır gluteni ilave edilmiştir. Deneme grubu olarak beslenen üçüncü grubun yemine ise inek başına günlük 44 g HMBi ilave edilmiştir. Süt verimi ve süt bileşimi açısından gruplar arasında bir fark görülmemiştir. Ancak istatistik bakımından önemli olmasa bile ineklerin % 4 yağa göre düzeltilmiş günlük süt verimleri, mısır gluteni ve HMBi ilave edilen gruplarda kontrol grubuna kıyasla sırası ile 1.86 ve 1.39 kg daha yüksek bulunmuştur. Aynı şekilde yemlerine mısır gluteni ve HMBi ilave edilen gruplara ait ineklerden elde edilen günlük süt kuru madde miktarı kontrol grubuna göre sırası ile 188.32 ve 70.66 g, süt yağı ise sırasıyla 111.56 ve 98.71 g daha yüksek bulunmuştur. Sonuç olarak mısır gluteni veya HMBi kullanımı ile düzeltilmiş süt veriminde istatistik öneme sahip olmamakla birlikte sayısal artış sağlanmıştır

Effects of supplementation with 2-hydroxy-4-(methylthio)-butanoic acid isopropyl ester on milk yield and composition of lactating dairy cows
Öz
The main objective of this trial was to determine the efficacy of a methionine supplement, 2-hydroxy-4(methylthio)-butaonic acid’s isopropyl ester (HMBi), on milk yield and milk composition of dairy cow. Trial was carried for 8 weeks in Per Farm, Kızılcahamam-Ankara. Trial design includes 3 different groups (control, positive control and trial group) each containing 10 animals and totally 30 animals were used for this experiment. Animals in the control group were fed on a diet which is not supplemented with any methionine source. In the positive control group, animals were fed a diet which is incorporated with corn gluten in order to provide 330 g methionine per cow each day. Animals in the trial group were offered a diet which is fortified with 44 g HMBi for each cow per day. Neither milk yield nor milk composition (protein, lactose, fat, solids-not-fat, total solids) was not affected significantly by supplementation HMBi or corn gluten meal. The 4% fat-corrected milk and milk total solids of the cows in the gluten meal and HMBi supplemented groups were numerically higher than those of the cows in the control group (1.86 - 1.39 kg/d -188.32 - 70.66 g/d, respectively). Milk fat yield of the cows in the gluten meal and HMBi supplemented groups was numerically (111.56 - 98.71 g/d respectively) higher than those the control group. In conclusion, corn gluten meal or HMBi supplementation can numerically increase milk production
