In an experimental head inside the Lebanon, oestrus hit their level that have typical time periods into the August and September but had been handled on a fairly high level up until December; off January in order to April the newest heats significantly diminished into the count, and you may out of May to help you July it ceased entirely. Along the latest oestrus cycle varied ranging from 15 and you can 20 months, with typically 18 weeks. The length of warms varied off sixteen so you’re able to 59 hours, that have 29 hours an average of. 9 for everypenny of heats were silent, just like the manifested by thickness regarding multiple schedules, followed by the new absence out of mating reaction (Barr, 1968). New Awassi ewe screens pair external signs and symptoms of oestrus. Pro-oestrus are small and alternatively indefinite as well as the onset of oestrus abrupt, as the cessation try gradual. Inside Iraq, the primary lambing 12 months out of Awassi ewes is in Zerovember, as well as in Lebanon, new Syrian Arab Republic and Israel into the December-January.
The fresh new mean pregnancy several months during the an Awassi group for the Lebanon has started considered 149.5 days to own male lambs and you can 148.six weeks for females (Choueiri, Barr and Khalil, 1966). In another Lebanese head, the average pregnancy size having solitary-created lambs is actually 151.2 days (Fox mais aussi al., 1971) when you are, within American University Ranch into the Lebanon, it absolutely was discovered to be 152.six weeks (McLeroy and you may Kurdian, 1958).
During the Bedouin and you will fellahin Awassi flocks, not more than 5 per cent of the adult ewes has twins. From inside the Lebanon, the newest lambing percentage of mature Awassi reproduction ewes usually averages in the 60. Within the Syrian Awassi flocks, virility is additionally lowest – 70-80 lambs for every 100 ewes. When you look at the fresh flocks with superior serving and repair, higher lambing prices (110-120) was basically filed. This new twinning price out of Awassi ewes does improve doing the age of six decades and you will decreases after that.
3 boys so you can 51.7 ladies. In a fixed head ordered out-of Syrian nomads, the number of guys exceeded regarding females; for the solitary lambs it was 52.4:47.six and in twins 57.4:42.6. 3:fifty.7; twenty two.8 % of your twin sets was indeed off male, 24.6 perpenny out-of lady, and 52.6 per cent regarding each other genders.
From inside the a group away from Anatolian Awassi sheep, the entire intercourse proportion of men to help you girls solitary and you will twin lambs try forty-two
The brand new facts regarding barrenness tell you a wide range in different flocks. Within the an excellent Lebanese flock where the ewes was in fact followed closely by rams regarding Summer in order to January, there were only 4 % barren ewes. For the a massive group, obtained away from half dozen some other regions in Lebanon, 10 percent of one’s ewes and that arrived to temperatures don’t mutton, ranging from dos per cent so you can twenty six per cent certainly one of regional organizations. Within the a fixed group where in fact the rams was basically leftover to the ewes throughout every season, 14 % did not lamb throughout one year. Into the Egypt, 20 percent of a group of Awassi ewes produced from Syrian inventory didn’t conceiveputer facts of the many milk products-filed Awassi ewes within the Israel during the one or two consecutive ages tell you an enthusiastic mediocre barrenness from 40.eight per cent when you look at the escort in Atlanta yearlings, 10.5 % in 2-year-olds, and you will 6.25 % inside adult ewes.
Into the an enthusiastic Awassi flock when you look at the central Anatolia, 20 percent of the ewes mated in one year and you will twelve % mated an additional year stayed bare
The new death rate from inside the Bedouin and you will fellahin Awassi flocks is 15-20 for eachpenny during the regular decades, and up in order to fifty percent in years off drought or significant winters (Hirsch, 1933). Although this describes flocks general, the new mortality out-of lambs is certainly not lower than that adult sheep. When you look at the Syrian Awassi flocks of the Sleepouin, the newest mortality away from lambs once beginning are at 5-10% in favorable many years, and 31-50 % in years which have cold winters and you will snowfall-shielded grasslands, in the event that ewes try starved. Within the fellahin flocks, kept in villages where the ewes mutton for the specialisttected urban centers and are given certain straw and additionally pasture, lamb mortality try less than when you look at the Bedouin flocks. Within the Iraq, famine and you may problem was reckoned to minimize the typical mutton crop so you’re able to forty-sixty percent (Williamson, 1949). Inside an experimental Awassi head from inside the Iraq, in which nourishment and management of the fresh new sheep try superior to men and women commonly used in Bedouin and you can fellahin flocks, solitary lambs demonstrated an average death rate regarding fifteen.7 % and twins 18.0 for eachcent during a six-season period. There clearly was a general interest within the Awassi flocks to possess men lambs for a significantly higher mortality speed within the earliest month off lives compared to women lambs. For the regions where Awassi isn’t local however, has been imported inside relatively quick number, death out-of lambs throughout acclimatization in a special microbial environment might be highest.
