Effect of Care Style on Milk Production of Shami Goats in the Coastal Region of Syria

This research was carried out in four different regions on the Syrian coast on four herds of Shami goats different in numbers. These were grown in different ways depending on farmers' concepts and needs, and the geographic location of each region. The number of goats that were studied was (44). The daily average of milk production per goat was calculated, in addition to the monthly average and overall average for every herd during the lactation season which was divided into two phases (Breastfeeding, Lactation) .In the first phase it was (2493,9 – 2238,6 – 1776,6 – 81,6) L ordered by herd and method of breeding (4 – 2 – 3 – 1) and same was in the second phase. The average production rate was (54,27)% in first method of first herd and in other methods was lower than (50)% and increased in other herds (49,39 – 45,36 – 44,16)% respectively (2 –4 – 3 – 1). It was noticed that in the second phase of Lactation the herd of first method retracted to lower than (50)%and rose in other herds (55,83 – 54,63 – 50,60 – 45,72 )% Respectively (1 –2 – 4 – 3). Statistical analysis demonstrated the lack of significant differences in second and forth herd in spite of the different methods used in the other herds, and in second phase statistical analysis was in four herds in accordance with different methods of breeding.

Calving Interval and Factors Affecting it in Friesian Cattle Under Libyan Conditions

Records of ٤٤٥ Friesian cows were analysed for calving interval and its components; days open, lactation length and length of dry period. The model included parity, calving year and calving season. The overall means were ٤٢٥,٧٧ ± ١,٨٩, ١٤١,٣ ± ١,٣٧, ٣٥٣,٩ ± ٠,٨٨ and ٧٣,٠٢ ± ٠,٧٧ days for calving interval, days open, lactation length and length of the dry period respectively. These estimates are high by tropical and subtopical standards, but they remain lower than the reproductive performance of Friesian cattle in temperate countries.
