Milk production characterization of Sohagi sheep
2009
Hamdon, H.A.M.
Milk yield and composition were determined in total of 118 Sohagi ewes. Lactation length, daily- milk yield, total milk pre-weaning, total milk post-weaning and total milk yield, respectively Lactation curve peaked around the second week of lactation and decreased thereafter. Season of lambing had a highly significant effect (P 0.01) on both milk yield , composition and lactation length., respectively Lactation curve peaked around the second week of lactation and decreased thereafter. Season of lambing had a highly significant effect (P 0.01) on both milk yield , composition and lactation length.).The differences due to number of suckling lambs were highly significant (P 0.01) with total milk yield, milk yield pre-weaning, milk yield post weaning and daily milk yield and significant (P 0.05) with lactation length.. Ewe age had significant effects and milk post-weaning, daily milk yield and composition. A highly significant (p 0.01) positive correlations was found between lambs birth weight and each of average daily milk yield or total milk pre-weaning. Also, a positive significant (p 0.05 and 0.01) correlations coefficients between weight ewes at lambing and each of average daily milk yield, total milk pre-weaning, total milk post-weaning, total milk yield or lactation length. Milk fat, protein, lactose, total solid, solid not fat, somatic cell count .There were a negative and significant (P 0.05and 0.01) correlations between daily milk yield with fat % total solid % protein % somatic cell count cells/ ml and milk energy ( MJ/L). The current results demonstrate that Sohagi sheep is non-dairy sheep. So sohagi sheep producers must follow intensive production system early weaning and early lambs fattening system.
