Growth performance, body composition, body conformation and meat quality were evaluated in crossbred pigs originating from three sire lines selected for leanness and conformation. The crossbred P, which was based on Belgian Piétrain had a leaner carcass and a better ham conformation compared to the other crossbreds. The presence of the halothane gene resulted in poorer meat quality in compariso...

In eusocial Hymenoptera, females are more tolerant towards nest-mate than towards non-nest-mate females. In solitary Hymenoptera, females are generally aggressive towards any conspecific female. Field observations of the nest biology of Manuelia postica suggested nest-mate recognition. Experiments were performed involving two live interacting females or one live female interacting with a dead f...

Increased economic incentive for producing young and leaner carcasses, as well as demand for lean meat from progressively health conscious consumers, are considered drivers for change in carcass composition over time. Furthermore, many retailers trim visible fat from meat to various degrees and consumers increasingly remove visible fat from meat prior to, or after, cooking. The objective of thi...

U consequences fuel the creative mind. The stuff of adventure in literature, their twists and turns wreak havoc in the science laboratory and the art studio alike. Frans Snyders, old master and founder of Baroque still life with animals, understood the unexpected and its power to surprise and used it to animate his work. A thriving arts market in 17th-century Flanders, supported by growing pros...

the objective of the current study was to investigate the effects of sex and carcass weight on the fatty acid composition in longissimus dorsi in zel lambs. thirty pasture reared lambs (15 males and 15 females) were randomly selected from local flocks. following slaughtering, the carcasses were assorted into two groups, according to their weights (>15kg and

Nine Duroc and thirteen crossbred (Hampshire x Yorkshire) growingfinishing barrows were fed two different diets: a typical cornhoybean basal diet and a diet consisting 85% of the basal diet plus 15% of almond hulls. Body composition was obtained by measuring total body electrical conductivity before and after the feeding trial. The upshot: Pigs fed the almond hulls ended up with 16% less body f...

Grazing endophyte-infected tall fescue (E+) negatively impacts cattle feed intake and growth negatively (Crawford et al., 1989). However, the interaction between environmental factors and animal genetics may influence important cattle growth measurements before and after the weaning process (Phillips et al, 2001). For example, polymorphisms (mutations) in the prolactin and cytochrome P450 genes...

A total of 480 pigs was used in an experiment conducted in a commercial research facility to determine the influence of fat additions to the growing-finishing diet on pig performance and carcass composition. Adding fat to the diet from 80 to 265 lb increased ADG and F/G by 1 and 2%, respectively, for each 1% added fat. The growth response was greatest during the initial phase of the trial (80 t...
