Periconceptional Heat Stress of Holstein Cows Affects Subsequent Production Parameters Measured During Adulthood
Periconceptional heat stress is known to reduce the likelihood of establishing pregnancy; however, some conceptuses will survive. Of the pregnancies that continue to term, a proportion will be heifers which are retained as replacement animals. Alterations that occur as a result of exposure to …

The effect of application of the FAMACHA© system on selected production parameters in sheep
… as can be seen from Tables 4.4.1 to 4.4.3. Wool production was not analysed in this trial due to faulty sample collection at shearing, but ideally it should have been included. Economic evaluation of the data initially showed that there appeared to be a benefit to dosing more frequently. During …

Comparison of broiler breeder production and fertility in a colony cage system with two different floors versus a slat-floor system
Two separate trials were conducted to compare egg production, egg weight, shell thickness, albumin height, fertility, and mortality of naturally mated broiler breeders maintained on either a slat and litter floor or in two tiered colony cages. In the first trial there was no difference (P > 0.05) …
