Sentence examples for culling rate from inspiring English sources

These results indicated that, at low levels of lysine intake, increasing lysine intake was beneficial for reducing sow lactation weight loss and culling rate of sow failing to display estrus within 21 d after weaning, while increasing lysine intake at high levels of lysine intake increased sow lactation weight loss and culling rate of sow failing to display estrus within 21 d after weaning.

We have computed disease prevalence in the population at equilibrium as a function of culling rate or hunting mortality for different values of age-dependent heterogeneity in transmission, called Δβ = βa−βj (where, βa is the transmission rate between adults and βj is the transmission rate between juveniles).

While the ideas being investigated in the present work are based on a detailed understanding of wild boar biology, the epidemiological model itself has been simplified to address the following key question: how do age-dependent heterogeneities in transmission interact with culling rate in the control of disease prevalence?

Impaired reproduction will result in additional inseminations, higher replacement rate and increased culling rate.

The two year culling rate in the herd was 44% (128/289 cows).

From weaning to 5-wk post-weaning, a total mortality and culling rate of 2.4% (4/168) was observed.

Culling rates before Days 90, 120, and 300 postpartum were 15.6%, 16.1%, and 28.6%, and 7.6%, 8.7%, and 15.9% for cows calving twins and singletons, respectively.

We tested the impacts of different spatio-temporal management strategies (i.e., culling rates, timing of culling during the year, spatial pattern of culling and strength of a barrier to immigration) on population response and efficiency.

In addition to culling rates, there are many potential factors that can determine efficiency of different management strategies, including demographic processes such as immigration rates, birth dynamics, and spatial ecology.

Reduced long-term productivity, decreased milk yield, and increased culling rates during first lactation have also been associated with FTPI [ 5, 6].

High BCS ap, as well as major losses in body condition have been associated with abomasal displacement, ketosis and other metabolism related diseases, decreased fertility and increased culling rates [ 2, 34, 35].
