This study investigated the effects of flock, sex and leg shape scores (assessed in the live animal) on the carcass yield, conformation and composition of purebred Texellambs. Two flocks were managed in a common environment. The first (Lean Index flock) had a 6-year history of selection for lean tissue growth rate using an index of live weight and ultrasonic muscle and fat depths measured at 20 weeks of age. The second (Conformation flock) had recently been established by mating rams of extreme conformation selected from the UK Texel population with ewes in the Lean Index flock. Lambs were evaluated at a mean age of 139 days at the end of an 11-week performance test in which they were reared indoors on a concentrate diet. Prior to slaughter, the lambs were assessed for conformation of the hind leg (leg shape score). Mean live weights and ultrasonic fat depths dia not differ significantly between flocks or leg shape scores but ultrasonic muscle depths were highest in the high leg shape score (27.9, 27.7 and 30.1 mm in low, medium and high scores, s.e.d. 0.55). At constant slaughter weight, the lean weight in the side was 04 kg higher in the Conformation flock and 0.3 kg higher in lambs of high v. low leg shape score (P < 0.001) with no significant differences in other tissue weights. Consequently, lean : bone ratio and lean proportions in both the live weight and carcass were higher in the Conformation flock and in lambs of high leg shape score. Lambs of high leg shape score had better carcass conformation scores (14.1, 12.9 and 11.9, for high, medium and low scores respectively, s.e.d. 0.30), shorter side length and higher values for alI muscularity traits. Lean tissue distribution in major joints and individual muscles dia not differ between flocks but the mean proportion of total lean in the higher priced cuts was higher (553.1 v. 543.9g/kg, s.e.d. 3.26) for lambs of high v. low leg shape score. Males were 6.5 kg heavier than females at scanning (P < 0.001), had lower ultrasonic fat depths (2.8 v. 3.2 mm; P < 0.01) but did not differ in ultrasonic muscle depths. At equal slaughter age, males produced 1 kg more lean tissue and had a higher proportion of lean in the side than females (665.2 v. 638.9 g/kg) but did not differ in lean proportion in the live weight, carcass conformation and muscularity scores. Females carried a higher proportion of totallean in the higher priced,cuts (55.6 v, 541.8 g/kg; P < 0.01) and in some individual muscles. It was concluded that there is !mportant varlatlon within the Texel breed in lean yleld at constant live weight and that this is likely associated wlth differences between strain and conformation type.

The semiarid northeast of Brazil contains a unique biome known as caatinga, with a maximum temperature of 40 ºC and a relativity humidity of 56%. The caatinga is characterized by a variety of plants, including Cereus jamacaru Dc (mandacaru), Poincianella microphylla Mart. ex G. Don (catingueira), Pilosocereus gounellei FAC Weber (xique-xique) and Mimosa tenuiflora (Willd.) Poir (jurema preta). Sheep and goat industries are economically strong in that region, despite the fact that caseous lymphadenitis is highly prevalent. The aim of the present study was to assess the survival and biofilm production of Corynebacterium pseudotuberculosis isolates in the invironment and under controlled temperatures (28°C, 37°C and 42°C) under different surfaces (plants, soil, wood, wire and thorns). In addition, we investigated the effects of applying the disinfectants chlorhexidine, hypochlorite and quaternary ammonia in soil, tiles, wood and vegetation cover. Four strains of C. pseudotuberculosis were selected (two from goats and two from sheep) for inoculation according to their in vitro biofilm production. Adherence to microplates was used to assess the biofilm-forming ability of the bacteria. Lower survival rates were observed when isolates of C. pseudotuberculosis were subjected to a temperature of 42°C. In terms of caatinga biome plants, contamination of jurema-preta plants resulted in the lowest survival rates. The disinfectant quaternary ammonia promoted a lower inoculum survival in all surfaces. The disinfectants and the higher temperature contributed to the reduction of biofilm production in isolates of C. pseudotuberculosis. knowledge of these patterns is important for the establishment of disease control measures, given the questionable efficacy of the treatment and the immuno-prophylaxis of caseous lymphadenitis.
