The dependence of residual feed consumption on development and tenderness of Brahman cattle, a typical breed chosen for crossbreeding cattle alongside the southern United States, together with Texas, was the main focus of a cattle feeding examine revealed in Utilized Animal Science journal.
The examine, “Relationships of residual feed consumption and residual common every day achieve with carcass traits and development of Brahman steers,” illustrates the impression residual feed has on physiological traits of Brahman steers within the Gulf Coast states, in keeping with researchers.
Residual feed consumption is the distinction of precise feed consumption from anticipated feed consumption of an animal for its dimension and is used to find out what quantity of feed is critical to take care of physique weight and/or weight achieve.
Monte Rouquette, Texas A&M AgriLife Analysis forage physiologist, was lead writer and carried out the examine on the Texas AgriLife Analysis and Extension Heart in Overton. Different collaborating researchers included Joe Paschal, retired Texas A&M AgriLife Extension Service livestock specialist and at the moment govt vp for the American Brahman Breeders Affiliation, School Station; Tanner Machado, animal scientist within the Division of Animal Science and Veterinary Know-how at Texas A&M College-Kingsville; Charles Lengthy, resident director, Overton; and David Riley, School of Agriculture and Life Sciences Division of Animal Science, School Station.
“This was really a crew effort of analysis scientists,” Rouquette stated.
Outcomes confirmed a linear relationship between the tenderness of meat to a steer’s residual common every day achieve. Probably the most environment friendly steers develop quickly, present passable maturation for harvest and usually produce a young carcass, Rouquette stated.
Feed consumption, efficiency outcomes
“The targets of this examine had been to measure feed effectivity information for yearling Brahman bulls and to find out the connection of those effectivity groupings to development, feedlot efficiency, carcass traits and tenderness of Brahman steers,” Rouquette stated.
Rouquette stated it was Randel’s idea to guage Brahman bulls for feed effectivity.
“We requested the query, ‘are these bull calves potential sires or steers?’ At sure ages, scrotum circumference was measured, semen high quality was evaluated in addition to temperament,” he stated.
There was additionally additional intrigue from the outcomes of the examine since Brahman cattle are crossbred all through the southern Gulf Coast.
“The Brahman crossbred cow has confirmed attributes of reproductive effectivity, longevity, and for adaptation to the vegetation and weather conditions of the Southwest and Gulf Coast States,” Rouquette stated.
Outcomes confirmed there’s a linear relationship between the tenderness of meat to a steer’s residual common every day achieve, he stated. Probably the most environment friendly steers develop quickly, present passable maturation for harvest and usually produce a young carcass.
The outcomes collected from the Warner-Bratzler Shear Pressure measurement technique indicated, “all steaks of Brahman steers had been thought of ‘tender’ and never ‘powerful’ by these measurements,” Rouquette stated.
Outcomes from this examine launched environment friendly methods to conduct and keep Brahman cattle from delivery to steak.
“From breeder, producer to client, implement administration methods for probably the most environment friendly manufacturing on pastures previous to cattle getting into the feedlot,” he stated. “This examine reinvents the accord of financial, environmental, and manufacturing development for Brahman steers.”
