This study was conducted to develop the prediction equations for 150 day milk yield on the cumulative part
lactation milk yield records of Awassi sheep in the southeastern region of Turkey. In the study, a total of 145 sheep
lambed during the 2007–2008 lambing year. Among the single monthly yields, the 3rd month (R
2 = 0.836) was the
best for 150 days prediction followed by 2nd and 4th month (R
2 = 0.756 and 0.659, respectively). Among the cumulative monthly yields, the TMY04
(R
2 = 0.982) was the best for 150 days prediction followed by TMY03
, TMY02
and
TMY01
(R
2 = 0.926, 0.797 and 0.659, respectively). The phenotypic correlation was the highest between the LSV150
and TMY04
(r = 0.991) followed by TMY03
, TMY02
and TMY01
(0.962, 0.893 and 0.775, respectively). It was concluded that the total milk yield of the first three month after lambing could accuratly be used to predict the total lactation milk yield of Awassi sheep if there is lactation
