Effect of cattle breed on finishing performance, carcass characteristics and economic benefits under typical beef production system in China

Abstract

This study compared the finishing performance carcass characteristics and economic benefits of two imported (Limousin and Simmental) and three local (Luxi, Jinnan and Qinchuan) cattle breeds slaughtered at 18.5 months of age under thetypical Chinese beef production system. All cattle (n=71) were reared under the same production system and fed the same finishing diet for 105 days. Eight bulls from each breed were randomly selected for slaughtering. Compared with the three local breeds, the two imported breeds had higher average daily gain, dry matter intake and gain efficiency. Regarding carcass characteristics, the two imported breeds had higher carcass weight, bone weight, net meat weight, and ribeye area (P<0.001). However, the local breeds had higher (P<0.01) marbling scores than the imported breeds. The imported breeds showed higher economic benefits (P<0.001) than the local breeds. In conclusion, the imported cattle breeds had better growth performance, carcass traits and economic benefits compared with the local cattle breeds at 18.5 months old under the typical Chinese feeding conditions whereas, in this study, the local breeds may have some advantage in terms of meat quality

Effects of Partial or Total Replacement of Maize with Alternative Feed Source on Digestibility, Growth Performance, Blood Metabolites and Economics in Limousin Crossbred Cattle

“…where ADG is the average daily gain (kg/head), MPBW is the average market price of body weight ($/kg), DMI is the daily DM intake (kg/head/d), and MPF is the market price of feeds ( Xie et al, 2012 ).…”

Assessing the sustainable development and intensification potential of beef cattle production in Sumbawa, Indonesia, using a system dynamics approach

“…In China, local cattle breeds fed a mixture of straw and concentrates in typical Chinese production system had ADGs of between 0.78 and 0.82 kg day -1 , while a rate of 1.5 kg day -1 was reported for imported Limousin cattle [ 26 ]. Cross breeds have also been found to perform better than local breeds in China, reaching heavier slaughter weights at a younger age [ 27 ]. The introduction of new genetics, possibly through cross breeding local and imported cattle, may provide additional gains to better feeding and animal management in Sumbawa.…”

“…They found that some farmers prefer open grazing to cut-and-carry feeding, because of difficulties in meeting the much higher additional labour requirements of the latter system. Other reasons why farmers may resist adopting the new system include perceived higher risks of animal theft in the more built-up areas that feedlots tend to be located as well as a lack of capacity in tree establishment and access to seeds [ 27 ].…”

Production de viande bovine en Chine et perspectives d’évolution

“…Xie et al (2012) ont comparé la vitesse de croissance et le rendement économique entre les taurillons (18,5 mois) de trois races locales (la Qinchuan, la Luxi et la Jin'nan) et de deux races importées (la Limousine et la Simmental) dans les mêmes conditions d'engraissement (typiques en Chine, tableau 1), le rendement économique étant calculé à partir de l'équation suivante :[(gain de poids pendant l'engraissement) × (prix par kg de poids vif)] / [coût des aliments pendant l'engraissement].Les résultats (tableau 2) ont montré que les deux races importées avaient une vitesse de croissance plus élevée (avec un gain journalier de 1,5 kg pour la race Limousine et 1,2 kg pour la race Simmental) que celle des races locales (0,78, 0,82 et 0,82 kg de gain journalier pour la race Qinchuan, Luxi et Jin'nan respectivement), et un meilleur rendement économique (1,89 et 1,68 pour la race Limousine et Simmental ; 1,52, 1,46 et 1,48 pour la race Qinchuan, Luxi et Jin'nan).…”
