Effect of compensatory growth on feed intake and feed conversion efficiency of heavyweight steers
Compensatory growth is an integral part ofNew Zealand beef production systems (Nicol and Kitessa, 1997) with restricted winter nutrition followed by good spring and summer feeding enabling a better fit with seasonal pasture production. Purchasers of store cattle (including feedlotters) often prefer animals with a previous history of perturbed growth because they believe they can benefit from hi...
متن کاملResidual Feed Intake and Feed Efficiency: Differences and Implications
In the beef production system, 70-75% of the total dietary energy is used for maintenance (Ferrell and Jenkins 1984; NRC 1996; Montaldo-Bermudez et al. 1990). Thus, while only 5% of the total life cycle dietary energy consumption is used for protein deposition in beef cattle, swine and poultry are more efficient at 14 and 22%, respectively. The relatively large size, slow maturity and slow repr...
متن کاملTest duration for growth, feed intake, and feed efficiency in beef cattle using the GrowSafe System.
This study was conducted to determine the optimum test duration and the effect of missing data on accuracy of measuring feed efficiency and its 4 related traits ADG, DMI, feed conversion ratio, and residual feed intake in beef cattle using data from 456 steers with 5,397 weekly averaged feed intakes and BW repeated measurements taken over 91 d. Data were collected using the GrowSafe System at t...
متن کاملEffects of intermittent feeding on compensatory growth, feed intake and body composition in Asian sea bass (Lates calcarifer)
This experiment was conducted to investigate the effects of various starvation and refeeding periods on growth, feed utilization and body composition in Asian sea bass (Lates calcarifer) with an average initial weight of 30.26±1.4 g (mean±SE). The fish were exposed to three different regimes: the control group fed twice daily to apparent satiation throughout the experiment (C), th...
متن کاملGrowth Performance and Feed Conversion Efficiency of Crossbred Heifers
Theexperiment was conducted to investigate the growth performance and feed conversion efficiency of crossbred heifer at different age level in Government Dairy Farm in Bogra, Bangladesh. Twelve female crossbred heifers were equally distributed (n=3) into four groups [Group A: (7±2 months), B: (12±2 months), C: (15±2 months) and D: (20±2 months)] according to age and fed concentrate mix, rice st...
