Buzağı ve Düvelerin Beslenmesi
Özet
Bu bölümde, buzağıların doğumdan sütten kesime; düvelerin ise damızlık yaşa ulaşana kadar geçen büyüme sürecinde uygulanması gereken temel besleme stratejileri ele alınmaktadır. Doğumdan sonraki ilk saatlerde verilen kaliteli kolostrum, pasif bağışıklığın sağlanmasında ve erken dönem kayıplarının azaltılmasında önemli bir rol oynar. Kolostrum döneminin ardından süt veya süt ikame yemleriyle besleme devam ederken, ilk haftadan itibaren buzağı başlangıç yemine geçilerek rumen gelişimi desteklenmelidir. Temiz ve taze suya erişim de erken dönemde sağlanmalıdır. Sütten kesme işlemi, buzağının günlük en az 1–1,5 kg katı yem tükettiği dönemde, kademeli olarak gerçekleştirilmelidir. Düve döneminde ise hedef, kontrollü büyüme ve zamanında cinsi olgunluğa ulaşmaktır. Bu süreçte enerji-protein dengesi sağlanmalı; vitamin (A, D, E) ve mineral (kalsiyum, fosfor, çinko) gereksinimleri karşılanmalıdır. Yetersiz ya da aşırı besleme, cinsi olgunlukta gecikme ve metabolik bozukluklara yol açabilir. Bu dönemde uygulanan bütüncül ve yaşa uygun besleme programları, ileriki dönemlerde yüksek verim ve sürü sağlığı açısından temel oluşturur.
This section outlines the fundamental feeding strategies to be implemented during the growth phase of calves from birth to weaning and heifers until they attain breeding age. The administration of high-quality colostrum within the initial hours post-birth is essential for conferring passive immunity and mitigating early mortality. After the colostrum phase, calves should continue to be fed milk or milk replacer, and from the first week, they must be introduced to starter feed to facilitate rumen development. Provision of clean and potable water should be ensured in the initial phases. Weaning should be implemented progressively when the calf ingests a minimum of 1–1.5 kg of solid feed daily. The objective during the heifer phase is regulated growth and prompt sexual maturation. Throughout this process, it is essential to sustain energy-protein equilibrium and fulfill the requirements for vitamins (A, D, E) and minerals (calcium, phosphorus, zinc). Insufficient or excessive nutrition can result in postponed sexual maturation and metabolic disorders. Thorough and age-suitable feeding programs established during this phase establish the groundwork for enhanced productivity and herd health in subsequent stages.
