Relationship of Backfat Thickness to Reproductive Performance of Gilts

The relationship of average backfat thickness of feedlot steers to performance

The length of time to keep cattle on feed that maximizes profits is determined by the point when incremental costs equal incremental increases in animal value. The primary cost in a cattle feeding enterprise is ration expense, so in order to effectively project optimal marketing time it is necessary to be able to determine future feed conversion. It is widely considered that feed conversion is ...

Effects of Gestational Housing on Reproductive Performance and Behavior of Sows with Different Backfat Thickness.

The present study investigated the effects of back-fat thickness at d 107 of gestation and housing types during gestation on reproductive performance and behavior of sows. A total of 64 crossbred sows (Landrace×Yorkshire) in their 3 to 4 parities were allotted to one of four treatments (n = 16) over two consecutive parities. During each parity, sows were assigned to two gestational housing type...

The relationship of average backfat thickness of feedlot steers to performance and relative efficiency of fat and protein retention.

Selection for growth and improved carcass merit has resulted in cattle that are variable in composition of gain during the finishing phase. This study assessed the relative performance among cattle with different levels of initial backfat thickness. It also exploited the ability to track carcass composition in the live animal with ultrasound estimates of backfat and marbling. A procedure was de...

Reproductive Performance of Rams to Biostimulation

The bio-stimulation technique offers a potentially useful and practical way for reproductive performance in rams. Reports on how bio-stimulation affects sexual potency rams are scarce: Knowledge of how rams respond to bio-stimulation is useful for persons who involved in semen collection; "hand" (controlled) mating, and the administration of sexual performance evaluations. The reduction of the ...
