Pastörize veya Çiğ Süt ile Beslenen Buzağılarda Vitamin Mineral Takviyesinin Ağırlık Artışı ve Sağlık Üzerindeki Etkilerinin Araştırılması

Abstract

Çalışmanın amacı, vitamin-mineral ikamesinin, çiğ süt veya flaş pastörize süt ile beslenen buzağılarda ağırlık artışı ve genel sağlık durumu üzerindeki etkilerinin araştırılmasıdır. Çalışmada iki farklı işletmeye ait 40 buzağı kullanılmıştır. A işletmesinde, 10 buzağıya günde iki kez çiğ süt ile birlikte 7,5 g. (15g/buzağı/gün) süt ikamesi yapılmış (AM grubu), diğer 10 buzağıya ikame yapılmamış ve 60 gün boyunca çiğ süt ile beslenmişlerdir (AC grubu). B işletmesinde, 10 buzağıya günde iki kez pastörize süt (72°C' de 15sn) ile karıştırılmış şekilde 7,5 g. (15g/buzağı/gün) süt ikamesi yapılmış (BM grubu), diğer 10 buzağıya ikame yapılmamış ve 60 gün boyunca pastörize süt ile beslenmişlerdir (AC grubu). Buzağıların canlı ağırlığı doğumu takiben ve sütten kesildikleri çalışmanın 60. gününde ölçülmüştür. AM, AC ve AM, BC gruplarında doğum ağırlıkları (kg±SEM) sırası ile 34,6±1,59, 34,6±1,68 ve 36,4±2,51, 36,8±1,40 olarak ölçülmüştür. Sütten kesim ağırlıkları (kg±SEM) AM, AC ve BM, BC gruplarında sırası ile 68,2±2,15, 65,9±1,89 ve 81,5±3,21, 72,8±2,38 olarak belirlenmiştir. Günlük Canlı Ağırlık Artışı (GCAA) (gr±SEM), AM, AC ve BM, BC gruplarında sırası ile 560±35, 522±25 ve 768±30, 600±19 olarak hesaplanmıştır. AM ve AC gruplarında GCAA benzer olmasına karşın, BM grubunda GCAA ve sütten kesim ağırlığı BC grubuna göre yüksek (P<0.05) bulunmuştur. Sonuç olarak, vitamin ve iz mineral ikamesinin pastörize atık süt ile beslenen buzağılarda canlı ağırlık artışı ve sağlık üzerine olumlu etkileri olduğu belirlenmiştir.

Effects of Vitamin and Trace Element Supplementation on Weight Gain and Health of Calves Fed Raw or Pasteurized Waste Milk

Abstract

The aim of the presented study is to investigate the effects of vitamin-mineral supplement on weight gain and health of dairy calves fed raw or pasteurized milk. The study was conducted on 40 calves from two different herds. Ten calves from herd A, received raw milk and 7.5 g of supplement twice daily (15g/calf/day) for 60 days (AM group); 10 other calves did not receive any supplement and were fed raw milk for 60 days (AC group).Ten calves from herd B (BM group), received 7.5 g of supplement twice daily (15g/calf/day) for 60 days mixed with pasteurized milk (72°C for 15 s). Calves in BC group (n:10) did not receive any supplement and calves in this group were fed with pasteurized milk for 60 days. Body weight of all calves were measured just after birth and on day 60 of the study when calves were weaned. Birth weights (kg±SEM) of groups AM, AC and BM, BC were 34.6±1.59, 34.6±1.68 and 36.4±2.51, 36.8±1.40 respectively. Weaning weights (kg±SEM) of groups AM, AC and BM, BC were 68.2±2.15, 65.9±1.89 and 81.5±3.21, 72.8±2.38 respectively. ADG (g±SEM) of groups AM, AC and BM, BC were calculated as 560±35, 522±25 and 768±30, 600±19 respectively. ADG and weaning weight of AM and AC was similar; however, ADG and weaning weight of BM was significantly higher (P<0.05) than ADG and weaning weight of BC. In conclusion, vitamin and trace element supplementation has beneficial effects on weight gain and health of dairy calves fed pasteurized waste milk.
