Sire SummariesSire Summaries By YearAdditions will be made as time permits and data is collected. Each year Alamo Cudal uses a number of bucks. The summaries below present information on the female progeny of each buck in each year from 1998. In many cases a single buck was used over several years. These are “linking” bucks and appear first in the list. Obviously this is a work in progress and there is a lag while progeny grow out, are tested and the data analysed. Bucks bred and used in the studs are selected on the Fineness Index as well as visual characteristics. Where available the Fineness Indexes are given for the sires used. Introduced sires do not have indexes but have usually been selected for size, fineness and visual characters similar to those sires selected from within the studs. To some extent the introduced sires are used for reducing inbreeding but there is a policy of introductions from new sources both for assessment of the source and the inclusion of new genetic material. The first three shearings are displayed here. While some does are lost from the system before the third shearing is complete a general pattern is still observable. Some of these figures are preliminary and there is a group of original Texan animals sires used in an AI program in 2001 who's progeny have been grouped together. A general observation is that while there are differences between years which can largely be explained in terms of feed supply resulting in consistent moves in body weight, fleece weight and fibre diameter, differences between sires within year seem small to insignificant. This may seem surprising however considering that the females are all from the one flock and the bucks have been selected by the one person, usually from performance records, this may explain the observation. If there is little difference between sires then it would seem that the only real source of additional genetic superiority would have to come from selection on the doe side of the flock. This is a radical suggestion and should be taken with care. As one senior NSW Agric. Sheep geneticist put it so colourfully, “Selecting ewes on performance is like pissing against Niagara Falls unless you are selecting the rams as well.” So here we have a real test of genetics in Angoras. What is the result of this selection program? How long will it take to make a difference and, what else has changed? Most breeders would claim that they are making changes but it would seem hard to prove from these data. And of course, if you don't measure anything you have no hope of demonstrating gains.

* indicates significant difference. Comment. Birth weights were high suggesting over feeding due to drought conditions. Weaning weights were also high, again indicating supplementation of lactating does increased kid growth. Growth to first shearing was restrained though first fleece weights and fibre diameters were somewhat exaggerated. Growth to second shearing was restricted and this was reflected in both poor 12 month body weights, staple lengths and fibre diameters. Good winter rains resulted in dramatic body weight increase to the third shearing and fleece weights were above expectation and staple lengths and fibre diameters were a little higher than normal. Alamo Cudal Sire Summary for 2005 - Female progenySires used: Phezulu Martini (PHZ 1768), Phezulu Futuris (PHZ A115), Phezulu Gregor (PHZ 1773), Phezulu Frere (PHZ B05), Alamo Afro Javelin (CTX D900 - SAFI=+33), Cudal Aftex Renegade 63 (CUD H038 - SAFI=+48).
* indicates significant difference. Comment. Again birth weights were high but weaning weights were lower than desired. First fleece weights were acceptable. Body weights at the second shearing were poor and fleece weight, length and diameter were correspondingly low. Third shearing body weights were on the low side and fleece weights were a little low. This was reflected in a relatively fine diameter.
Alamo Cudal Sire Summary for 2004 - female progenySires used: Cudal Texan Quark 3 (CUD D026 - SAFI=+248), Phezulu Imbazzi (PHZ 1738), Phezulu Martini (PHZ 1768), Phezulu Futuris (PHZ A115), Alamo Aftex Quartz 23 CTX D709 - SAFI=+129)
* Significant difference Comment: This drop had a noticeably higher birth weight. Weaning and first shearing body weights were low as was the 12 month fleece weight indicating a poor year. The first shearing data seemed relatively normal and for the first time, first shearing fibre diameters were measured giving a low average. Second shearing fleece weights, lengths and fibre diameters were lower than expected due to the poor season. Values for the third shearing fleeces were also lower than anticipated.
Alamo Cudal Sire Summary for 2003 - females progenySires used: Cudal Texan Quark 3 (CUD D026- SAFI=+248), Cudal Aftex Quartz (CUD D300 SAFI=+33), Cudal Aftex Democrat 10 (CUD D419 SAFI=+124), Alamo Afro Rhodes (CTX D677 SAFI=+60)
* significant difference Comment: Birth weights were high but weaning and 6 month body weights were low. Despite this the first shearing fleece weights were relatively high. Second fleece weights and lengths were somewhat low and fibre diameters were surprisingly low reflecting the poor body weights related to drought. Third shearing body weights were again lower than desired but this was reflected in the relatively low fibre diameters.
Alamo Cudal Sire Summary for 2002 - female progenySires used: Topbok Mandela (TPI 22), Topbok Rhodes (TPI 30), Cudal Texan Justice (CUD C355 - SAFI=+84), Cudal Aftex Rhodes (CUD C689 - SAFI=+96), Cudal Texan Quark 3 (CUD D026 - SAFI=+247), Cudal Afro Republican (CUD D023 - SAFI=+58)
* Significant difference Comment: Birth weights and weaning weights were a little high though the first shearing body weights were not that high. First fleece weights and lengths seem to reflect the favourable early growth rates. Second shearing body weights were not high but fleece weights were good and lengths favourable. Fibre diameters were at the high end of the acceptable range. Third shearing body weights were not that high but fleece weights were good and both length and diameters were seemed to reflect the more favourable growth conditions.
Alamo Cudal Sire Summary 2001 drop - female progenySires used: Topbok Mandela (TPI 22), Cudal Texan Justice (CUD C355 - SAFI=+84), Cudal Aftex Rhodes (CUD C689- SAFI=+97), Syndicate of 6 original Texan imports (TI)
* significant difference Comment: Birth weights and weaning weights were low this year though the first fleece weight seemed to be almost normal. While 12 month body weights were a little low, lengths were normal and fibre diameters were disappointingly still too high. For the first time the third shearing body weights were taken. At this shearing fleece weights were high as were the lengths and diameters. While the Texan progeny had lower estimated yields, there was no measured effects suggesting a poorer growth rate or other differences commonly suggested for the Texan imported material. It is possible that hybrid vigour cancelled some effects though the subjective assessments seemed to reinforce the opinion that the Texan progeny "fail to do well".
Alamo Cudal Sire Summaries for the 2000 drop - female progenySires Used: Topbok Mandela (TPI 22), Topbok Rhodes (TPI 30), Cudal Texan Justice (CUD C355 SAFI=+84), Alamo Aftex Premier 3 (CTX C732 SAFI=+68), Cudal Aftex Chief 9 (CUD C044 SAFI=+29)
* significant differences Comment: Birth weights seemed a little low and weaning weights were very low, as were both 6month and 12 month body weights reflecting the poor year. The first and second fleece weight were also low and the second fleeces were shorter and finer than expected and the CV2 was higher than expected. The third fleece seemed to reflect the improved conditions with longer and broader fibre.
Alamo Cudal Sire Summary for the 1999 drop - female progenySires Used: Alamo Aftex Chief 3 (CTX A910), Phezulu Afro Warrior (PHZ 766), Topbok Mandela (TPI 22), Topbok Rhodes (TPI 30), Cudal Aftex Chief 13 (CUD C095 SAFI=+24), Alamo Aftex Justice (CTX C334)
! indicates mating to kids, * indicates significant differences Comment: Again weaning weights were somewhat low though fleece weights and lengths were as expected. Late spring and summer were favourable with animals gaining weight to the first shearing and weight gains to the second shearing were normal. Second fleece weights were a little low but fibre diameters were higher than expected. Third fleece weights were quite low as were staple lengths fibre diameters seemed as expected. Alamo Cudal Sire Summary for the 1998 - female progenySires used: Toolangie Sentimental Bloke 2 (SDW 951), Alamo Blaze 2 (CTX A518), Alamo Aftex Chief (CTX A910 ), Alamo Afro Rex (CTX C035 - SAFI=+102), Phezulu African Warrior (PHZ 766), Alamo Chieftan 4 (CYX C133 - SAFI=+103)
Comments: Weaning this year seems to have been at a light weight suggesting a poor season though first fleece weights were about normal. Second shearing body weights were as expected. Seconf shearing fibre diameters were a little higher than might have been expected but stalpe lengths were also high. Third fleece weights were below expectation though fibre diameters were about normal.
