The Booroola Merino Breed, developed in Australia, is a valuable genetic resource for increasing biological fecundity
in sheep worldwide. The purpose of this study was to summarize information about the Booroola Merino breed and its
use worldwide and in Bulgaria for increasing the reproductive potential of Merino sheep and other breeds. The positiv...

... tendency for a gradual reduction of differences in live weight with increasing age of the animals was established, and at 2.5 years the advantage in favor of purebreds was only 3.04% (Table 6). The fecundity of purebred sheep at 2.5 and 3.5 years was 117.1% and 111.4%, respectively, and for animals with Booroola blood -141.5% and 137.5% (Table 7). In another study, Dimitrov (2006) investigated the influence of the Booroola-blooded breed on the wool production and natural wool length at 1.5 and 2.5 years of age of sheep of the Shumen inbred type of the NEBM breed. ...Similar publications
Growth traits are one of the focuses of sheep breeding, and growth curve is an effective method to describe growth traits. The body weight of Yiling sheep at 0, 120, 180, 360 and 540 days of age were fitted with five common nonlinear growth models: Logistic, Gompertz, Von Bertalanffy, Brody and Negative exponential, and the growth models were evalu...
This study aimed to identify insertion–deletion (InDel) variants in key genes of the Hippo signaling pathway in four Chinese sheep breeds: Tong sheep (TS), Hu sheep (HS), Small Tail Han sheep (STHS), and Lanzhou large-tailed sheep (LLTS). InDel variants in MST1/2, LATS1/2, SAV1, MOB1A/B, and YAP/TAZ genes were screened using public databases and id...
(1) Background: The Hulunbuir sheep is a Chinese local sheep breed with good meat quality and exceptional cold-stress resilience. However, the growth performance of the Hulunbuir sheep is lower when compared to that of commercial breeds. Growth traits such as body weight and body size are critical, as they directly influence the meat production in...
This is aimed to calculate the general combining ability (GCA), specific combining ability (SCA), and heterosis estimates for reciprocal crosses of M erino, M orkaraman, and Awassi sheep breeds. The performance data received from M orkaraman, M erino, and Awassi sheep flocks and their crosses kept at the Atatürk University High School farm were ana...
The aim of this study was to compare the values of echocardiographic parameters in healthy Santa Inês sheep with standardized values for normal Brazilian human adults. Two-dimensional echocardiography, Movement mode, and pulse wave and color flow Doppler were performed in 39 non-sedated young adult sheep of Santa Inês breed. Dimensions such as the...
