Effect of Feed Additives on Nutrient Intake and Feed Efficiency of Lactating Crossbred Cows

Genetic Regulation of Feed Efficiency in Lactating Holstein Cows

Growth 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...

Black gram (Vigna Mungo L.) foliage supplementation to crossbred cows: effects on feed intake, nutrient digestibility and milk production

OBJECTIVE An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L.) on feed intake and utilization, and production performance of crossbred lactating cows. METHODS Eighteen lactating crossbred (Bos taurus×Bos indicus) cows (body weight 330.93± 10.82 kg) at their second and mid lactation (milk yield 6.77±0.54 kg/d) w...

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...

Residual 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...
