Hindistan’da Küçük Ölçekli Süt İşletmeleri Arasında Klinik Mastitis İnsidansı

Öz

Bu çalışmada, bireysel sürülerde mastitis kontrolünü destekleyen tahminler yapabilmek ve planlama sürecinde mastitisin ekonomik kayıplarını azaltmak amacıyla küçük ölçekli çifliklerde süt inekleri arasında klinik mastitis insidensi araştırılmıştır. Çok kademeli tesadüfi örnekleme tekniği, Ocak-Mart 2013 tarihleri arasındaki dönemde toplamda 110 süt ineği popülasyonunda, etkilenmiş olan ineklere sahip 40 haneden seçim yapmak için uygulandı. Çiftçilerin okur yazarlığı, aile büyüklüğü, laktasyon sayısı ve mevsim ile mastitis insidansı arasındaki ilişki son derece anlamlıydı (P<0.01) ayrıca ırk, süt verimi, laktasyon dönemi, meme morfolojisi, çiftlik yönetimi, zemin tipi, yetiştiricinin tırnak kesme alışkanlığı ve geçmişte oluşmuş mastitis ile var olan mastitis insidansı arasındaki ilişki önemli bulunmuştur (P<0.05). Mastitis yaygınlığının; yağışlı mevsimlerde, beşinci laktasyon sırasında olan Siyah Alaca melezlerinde, 15 litreden daha fazla süt veren, sarkık meme yapısına sahip (%60.00), daha önceden mastitis geçirmiş ve çamurlu toprak zeminde barındırılan hayvanlarda laktasyonun erken döneminde (%53.65) daha yüksek olduğu saptanmıştır.

Incidence of Clinical Mastitis Among Small Holder Dairy Farms in India

Abstract

This study examines the incidence of clinical mastitis among dairy cattle under small holder farming condition to facilitate derivation of economic weight of mastitis in the planning process. Multistage random sampling technique was adopted to choose the final 40 households having cows affected from a population of total 110 dairy cows during the period between January and March 2013. The association of literacy of farmers, family size, lactation numbers and season with the incidence of mastitis was highly significant(P<0.01) and the association of breed, milk yield, stage of lactation, udder morphology, management practices, type of floor, nail cutting habit of milk-man and previous occurrence of mastitis with the current  incidence of mastitis was significant(P<0.05). The mastitis incidence was more prevalent in fifth lactation during rainy season, in crossbred Holstein Friesian, in higher average daily milk yield of more than 15 litres, during early stage of lactation (53.65%), in cows having pendulous udder (60.00%) and previous occurrence of mastitis, and in cows kept on muddy soil floor.
