“…Breed selection may be more effective for decreasing the incidence of IBK, but it would need to be balanced by other breed characteristics. For example, the crossbred calves sired by tropically adapted breeds evaluated in this study were more resistant to IBK than most other Bos taurus groups, but they may have less desirable carcass characteristics (Crouse et al, 1989).…”

Infectious bovine keratoconjunctivitis (IBK) is one of the most economically important diseases in preweaned calves. This study examined the health records of 45,497 calves over a 20-yr period to determine environmental and genetic factors influencing the incidence of IBK. Three data sets were analyzed with an animal model. The first data set (n = 41,986) evaluated environmental factors and genetic differences among nine purebred (Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Pinzgauer, Red Poll, and Simmental) and three composite breeds (MARC I, MARC II, and MARC III). Weaning weights of calves diagnosed with IBK were 8.9 kg lighter (P < 0.05) than weights of healthy calves. Incidence of IBK was related to age of the calf and the seasonal life cycle of the face fly (Musca autumnalis). Incidence of IBK increased in the spring (June), peaked during the summer months (July to September), and then decreased in the fall. Herefords were the most susceptible breed (P < 0.05) compared with all other purebreds and composites. Estimates of direct heritability for the incidence of IBK were generally low and ranged from 0.00 to 0.28 by breed. The maternal permanent environmental and

“…Over 50% of the national herd is estimated to have some Brahman genes (Bindon 2002). However, it is well documented that as the proportion of Bos indicus inheritance increases, shear force (SF) increases and marbling and sensory tenderness values decrease (Koch et al 1982;Crouse et al 1989;Whipple et al 1990;Marshall 1994;Shackelford et al 1995;Cundiff et al 1998;Thompson et al 1999a;Wheeler et al 2001;Thompson 2002). While there have been many studies comparing cattle with varying proportions of B. indicus genes to Bos taurus animals in temperate environments, there are few studies comparing B. indicus with B. indicus · B. taurus crosses in tropical and subtropical environments.…”

Brahman and Brahman crossbred cattle grown on pasture and in feedlots in subtropical and temperate Australia. 2. Meat quality and palatability

Abstract. Market demand for a reliable supply of beef of consistently high eating quality led the Cooperative Research Centre for Cattle and Beef Industry (Meat Quality) to initiate a crossbreeding progeny test program to quantify objective and sensory meat quality differences between straightbred and first-cross Brahman cattle. Brahman, Belmont Red, Santa Gertrudis, Angus, Hereford, Shorthorn, Charolais and Limousin sires were mated to Brahman females over 3 years to produce 1346 steers and heifers in subtropical northern Australia. Calves were assigned within sire by age and weight to one of three market endpoints (domestic, Korean or Japanese), one of two finishing environments (subtropical or temperate) and one of two finishing diets (pasture or feedlot). Average carcass weights were 227, 288 and 327 kg for domestic, Korean and Japanese markets respectively. Only steers were finished for the Japanese market. The effects of sire breed, finishing regime, market endpoint and sex on sensory meat quality of four attributes score (CMQ4), ossification score and Warner-Bratzler shear force (SF), instron compression (IC), ultimate pH and percent cooking loss (CL) on the M. longissimus thoracis et lumborum (LT) and M. semitendinosus (ST) were determined. Straightbred Brahmans had the highest SFLT (5.39 AE 0.07; P < 0.001), ICLT (1.89 AE 0.02; P < 0.05) and CL in both muscles (P < 0.05). Straightbred Brahmans were the only genotype that failed to meet minimum CMQ4 grading standards (38.3; P < 0.001). Progeny with up to 75% Brahman content successfully met minimum objective and sensory meat quality consumer thresholds for tenderness (IC <2.2 kg, SF <5.0 kg; CMQ4 >46.5). There was little difference between crossbred progeny for most meat quality traits. All feedlot-finished animals were slaughtered at domestic, Korean and Japanese market weights by 24 months of age, with minimal differences in objective measures of meat quality between markets. The IC measures for all sire breeds were below 2.2 kg, indicating connective tissue toughness was not an important market consideration in feedlot-finished animals slaughtered by 24 months of age. Pasture finishing adversely affected all meat quality traits (P < 0.001) except CLST, with Korean and Japanese market animals having unacceptably tough SF, IC and CMQ4 measures. This was attributed to their older age at slaughter (31 and 36 months respectively), resulting from their seasonally interrupted growth path. While domestic animals slaughtered at 25 months of age off pasture had unacceptably high SF and IC, CMQ4 was acceptable. Subtropical feedlot animals had slightly more desirable (n.s.) SF and IC relative to temperate feedlot animals, whereas temperate feedlot animals had higher CMQ4 (P < 0.001). Genotype · environment interactions were not important.

“…Evidence of the effect of calpastatin and collagen on tenderness when Brahman is included in the breeding is presented by Riley et al (2005). Additionally, Crouse et al (1989) found that with an increase in Bos indicus inheritance, an increase in shear force values was observed. Previous studies have demonstrated that enhancement lowers shear force values (Wicklund et al, 2006).…”

“…Lower WBSF values in HCF when compared to HDP could have been a result of breed differences between these treatments, as well as a dietary effect, and/or variable age at slaughter. Tenderness in Bos indicus cattle can be of concern, especially as the percentage of Bos indicus increases (Crouse et al, 1989). High shear force values of steaks from Bos indicus cattle can be influenced by the elevated calpastatin levels (Whipple et al, 1990) and less intramuscular fat (Highfill et al, 2012).…”

“…Additionally, fat deposition varies depending on breed or biological cattle type with Bos taurus having a higher fat deposition than Bos indicus (Crouse et al, 1989;Warren et al, 2008). Previous studies suggest breed variance can increase intramuscular fat to improve meat palatability traits (Muir et al, 1998;Sadkowski et al, 2014), ultimately affecting meat quality and acceptability with the consumer (Koch et al, 1976;Koch et al, 1979;Maughan et al, 2012).…”

Abstract:Our objective was to evaluate the effects of different Honduran cattle production systems, enhancement, and country of origin on palatability of the longissimus muscle aged 21 d postmortem as determined by U.S. and Honduran consumers (n = 240/country). U.S.-sourced strip loins (n = 10/treatment) were selected: USDA Select (SE) and Top (upper 2/3) Choice (TC). Honduran-sourced strip loins (n = 10/treatment) included: 1) dual-purpose bulls, raised on native pasture (HDP), 2) F1 crossbred Brahman bulls finished on a corn-based grain diet for 180 d (HCF), and 3) purebred Brahman bulls finished on a sugarcane-based diet for 180 d (HSC). Ten additional strip loins from each Honduran treatment were selected and enhanced (E; 112% ± 3.5%) with water, salt, and tripolyphosphate, resulting in EHDP, EHCF, and EHSC. Steaks were cooked to 77°C prior to consumer evaluation of tenderness, juiciness, and flavor and overall liking, with classification of each trait as acceptable or unacceptable. Consumers indicated if they were willing to pay 0, 3, 6, or 10 USD/0.45 kg. Consumer data were analyzed using the GLIMMIX procedure of SAS as a split plot design, with treatment as the whole plot factor and country and the country × treatment interaction as the subplot factors, including panel as a random effect. The EHCF had greater (P < 0.05) scores for tenderness, juiciness, flavor and overall liking. No differences (P > 0.05) were found between TC and SE when scoring palatability traits, but more (P < 0.05) consumers found TC acceptable for juiciness compared to SE. Honduran consumers ranked all palatability traits greater than U.S consumers and found a greater percentage of samples acceptable for tenderness (P < 0.05). Enhancement of Honduran treatments had a positive effect on palatability traits, as well as the acceptability of those traits. Regardless of the differences in breeds, using high-energy diets and enhancement resulted in greater palatability scores.
