Considerations for Improving Feed Efficiency in Dairy Cattle
Intensive selection of sires is possible by using artificial insemination; coupled with accurate measurement of a potential sire’s genetic value, this has markedly improved genetics for easily measured traits like milk production and type traits. Increased milk production has in turn increased gross feed efficiency through dilution of maintenance. Additional genetic gains in feed efficiency wou...

The PTB-Simherd is a dynamic, stochastic, and mechanistic Monte-Carlo model simulating adairy herd including young stock. Paratuberculosis and relevant control strategies against thisdisease was built into an existing simulation model. The model is able to simulate bothepidemiological, technical and economic consequences of paratuberculosis and controlstrategies against it in th...
متن کاملEconomic Cost of Lameness in Dairy Cattle Herds
The competition among dairy producers is sharp nowadays. In this challenging situation the dairies are able to survive by the continuous increase in the efficiency and thereby the profitability of their production. The level of animal health is a basic influential factor of the profitableness on dairy farms, thus, it is very helpful to reveal the herd diseases resulting in the largest economic ...
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...
