Abstract
The objectives of the present study were to study the effect of breed of ram and yeast supplementation on some of reproductive and productive traits on Barki ewes.
The study was carried out at the faculty of agriculture (Saba Basha), Alexandria
University at Abis during the period from January 2009 till May 2010.
Seventy two ewes Barki aging 2-5 years were divided into four similar groups according to age and weight. Each group of eighteen ewes animals. Two groups were mated with
Awaasi ram and another two groups were mated with Barki ram.
The animals were divided into two equal groups, I- control group (n=18 animals) received no supplementation, II- experimental.
The second group (n=l8 animals) received 0.6 gm Saccharomyces cereviside was added daily to 0.6 kg of the concentrate ration.
The data collected from one lambing seasons (i.e. June 2009 till May 2010). The results could be summarized as follows:
- Ewes mated to Barki ram had higher fertility traits ewe conceived per ewe joined (EC/EJ)
or conception rate (CR), ewe lambed per ewe joined (EL/EJ). Number of lambs born per
ewe joined (LB/EJ), and number of lambs weaned per ewe joined (LW/EJ), except for kilograms born or weaned per ewe joined
- Fertility traits (i.e. EC/EJ, EL/EJ, LB/EJ, LW/EJ, KGB/EJ and KGW/EJ) tended to increase as live body weight of ewe at mating increased from 35kg to 50kg.
- The fertility traits tended to increase with age of the ewe up to 5 years old. The lowest average was for ewes of two to three years
- Live yeast culture supplemented to the Barki ewes had not significant effects on number of ewe conceived per of ewe joined (EC/EJ), number of ewe lambed per ewe joined (EL/EJ), number of lambs born per ewe joined (LB/EJ), number of lambs weaned per ewe
joined (LW/EJ), but had a significant effects on number of kg born per ewe joined (KGB/EJ) and number of kg weaned per ewe joined (KGW/EJ) in Barki Sheep mated with Awassi ram or Barki ram.
- Barki Ewes mated to Barki rams (Barki ewes) or Awassi rams differ significantly in all of
the reproductive traits studied .Lambs born alive per ewe lambing (LB/EL) lambs weaned per ewe lambing (LW/EL) kilograms born per ewe lambing (KGB/EL) and kilograms. Weaned per ewe lambing (KGW/EL)
- The effect of weight of ewe at mating had significant effect on LW/EL, KGB/EL and KGW/EL However ewes weighing 45-50kg born and weaned gained the heaviest lambs while ewes weighing 35 to 40kg born and weaned gained scored the lightest lambs.
-Lambs born/ewe lambed and Lambs weandlewe lambed tended to increase with age of the ewe up to 5 years. However KGB/EL and KGW/EL were higher for ewes at 5 years.
-Live yeast culture supplemented to the Barki ewes had insignificant effects on number of
Lambs born alive per ewe lambing (LB/EL) and lambs weaned per ewe lambing (LW/EL)
but had a significant effects on kilograms born per ewe lambing (KGB/EL) and kilograms weaned per ewe lambing (KGW/EL) in Barki Sheep mated with Awassi ram or Barki ram
- Breed of lambs affected on body weight of lambs at birth, 4 weeks, 8 weeks and weaning age. The Y2Awassi*Y2Barki lambs were heavier than Barki lambs at all ages. The Sex of lambs had a significant effect (P S 0.05) on body weight of lambs at birth, 4 weeks, 8 weeks and 12 weeks weaning age. The Type of Birth of lambs had a significant effect(P<0.05) on body weight oflambs at birth, 4 weeks, 8 weeks and 12 weeks weaning age
