“…Manajemen pemeliharaan pedet tergolong baik, jika mortalitas 1%, sedangkan apabila mortalitas mencapai angka sebesar 20%-25%, menunjukkan manajemen pemeliharaan yang buruk. Selain itu, tingkat mortalitas pedet dipengaruhi oleh musim, hal ini sesuai dengan pernyataan Uza & Adee (2005) bahwa tingkat kematian pedet saat musim dingin lebih tinggi daripada saat musim panas. Kematian pedet pada musim panas disebabkan oleh kekurangan nutrisi, akibat penurunan konsumsi pakan.…”

The research was carried out to decrease the mortality rate of Bali calves. This research was conducted at the Trial Farm of BPTP NTT for 3 years, it started in 2016 until 2018. The material used in this research was Bali calves, communal shed, and separate shed. The data collection system is carried out by observing the population of Bali calves every year. In 2016-2017, Bali calves were maintenanced in communal shed; in 2018-2019 in a separate shed. The results of Bali calves mortality research were highest in 2017, that was with the calves maintenance system combined in communal shed with adult cattle. After the treatment of Bali calves separation from broodstock in 2018, the percentage of mortality rate decreased. The high mortality rate of calves is one of them caused by competition in feed between adult cows and Bali calves which causes nutrition obtained by calves for a period of growth and development was not optimal. The steps to reduce the mortality rate i.e separation of Bali calves from adult cows in a special of Bali calves separation shed.

Bu çalışmada, entansif süt sığırcılığında buzağı hastalıkları ve ölümlerine bağlı ekonomik kayıpların belirlenmesi amaçlanmıştır. Çalışma, Ekim 2020 ile Ekim 2021 tarihleri arasında Kayseri-Develi’de bulunan özel bir damızlık süt sığırı işletmesinde toplam 1147 buzağı verisi kullanılarak yapılmıştır. Çalışma boyunca incelenen buzağılar D1 (sağlıklı), D2 (hastalanıp iyileşen) ve D3 (hastalanıp ölen) şeklinde üç farklı duruma ayrılmıştır. Çalışmada, sağlıklı buzağılar için sadece büyütme maliyeti hesaplanırken, hasta buzağılar için ilave işçilik, veteriner hekim, altlık ve ilaç/ tedavi masrafları hesaplanmıştır. Ölen buzağılar için ise ilave işçilik, veteriner hekim, ilaç/tedavi masrafı ile ölen buzağı bedeli hesaplamalara dâhil edilmiştir. Ölen buzağı bedeli belirlenirken TİGEM tarafından ırklara ve cinsiyete göre belir- lenen buzağı fiyatları dikkate alınmıştır. Çalışma bulgularına göre, hasta buzağı sayısının 626 (%54.6), hastalık (vaka) sayısının ise 809 (%70.5) ve buzağı ölüm oranının %13.3 olduğu belirlenmiştir. Buzağı hastalık ve ölümleri üzerinde anne yaşının, annenin laktasyon sayısının, doğum mevsiminin, babanın (boğa), buzağı ırkının, kolostrum alma duru- munun etkili olduğu tespit edilmiştir (P

IntroductionIn sub-Saharan Africa, pre-weaning young stock mortality (YSM) is in the order of 20 to 30% across most livestock species and production systems. High YSM has significant economic implications for livestock keepers, but few studies provide estimates of the “cost of YSM.” This study explores a bio-economic herd modeling approach to estimate the “cost of YSM” at farming/livestock system level.MethodsThe static zero-growth version of DYNMOD was used to calculate the annual physical and monetary output of a sheep flock consisting of 100 breeding females at different levels of lamb mortality. Production parameter values and prices were taken from recently published research. Calculations were carried out for values of lamb mortality decreasing from 30% to 0% in 5% intervals, with 20% representing the “baseline” YSM. Calculations were repeated for a “high” fertility scenario (100% vs. 59% parturition rate) to gauge the sensitivity of the cost of YSM to another parameter determining flock productivity.ResultsThe relation of revenue per head and YSM is close to linear over the range of analyzed YSM with 1% decrease in YSM resulting in an increase in revenue per animal of approximately 1%. At the higher fertility rate, the absolute cost of YSM to sheep farmers is higher while the relative increase in revenue per animal resulting from YSM reduction is lower. The estimated difference in revenue of the 100-ewe flock between the 20% and 0% lamb mortality scenarios (at baseline fertility) amounts to approximately USD 90 per additionally surviving lamb, which is far above its market value.DiscussionReduced lamb mortality ultimately impacts flock revenue through increased sales of “mature” animals, which embody the value of a lamb plus the revenue/profit from raising it to marketable age/weight. The modeling results suggest that foregone profit is an important component of the systemic “cost of YSM.” Consequently, expected profit per animal, in addition to its current market value, is essential for estimating the absolute cost of YSM at farming system level.
