Prediction of Fattening Final Live Weight from some Body Measurements and Fattening Period in Young Bulls of Crossbred and Exotic Breeds using MARS Data Mining Algorithm

Pakistan Journal of Zoology, 2018
The aim of this investigation was to develop a prediction equation for fattening final live body weight from several body measurements and fattening period of native, crossbred and exotic breeds. For this aim, a total of 103 young bulls were used. In the prediction of fattening final live weight as an output variable, several continuous predictors ...

Crossbred evaluations using single-step genomic BLUP and algorithm for proven and young with different sources of data [PDF]

Journal of Animal Science, 2019
Genomic selection (GS) is routinely applied to many purebreds and lines of farm species. However, this method can be extended to predictions across purebreds as well as for crossbreds. This is useful for swine and poultry, for which selection in nucleus herds is typically performed on purebred animals, whereas the commercial product is the crossbred ...

Prevalence, Associated Factors, and Temporal Trends of Brucella Detection Across Human and Animal Hosts in Bangladesh: A 25-Year Meta-Analysis. [PDF]

Vet Med Sci
This systematic review and meta‐analysis synthesizes Brucella prevalence across human and animal hosts in Bangladesh. Dogs showed the highest prevalence (7.49%), followed by goats (3.86%), cattle (3.67%), humans (2.94%), and horses (1.78%). Abortion history was significantly associated with Brucella infection, underscoring the need for integrated One ...

Evaluation of Precision and Accuracy of a Cattle Behavior Sensor for Monitoring Sheep in Indoor and Pasture Systems [PDF]

Sensors
The use of sensors applied to precision livestock farming is widespread in many farm species, especially dairy cattle, but there is a dearth of sensors validated for sheep farming.

Combined Infrared Thermography and Agitated Behavior in Sows Improve Estrus Detection When Applied to Supervised Machine Learning Algorithms [PDF]

Animals
The identification of estrus at the right moment allows for a higher success of fecundity with artificial insemination. Evaluating changes in body surface temperature of sows during the estrus period using an infrared thermography camera (ITC) can ...

New Low-Memory Algebraic Attacks on LowMC in the Picnic Setting

IACR Transactions on Symmetric Cryptology, 2022
The security of the post-quantum signature scheme Picnic is highly related to the difficulty of recovering the secret key of LowMC from a single plaintext-ciphertext pair.

Improved Attacks on LowMC with Algebraic Techniques

IACR Transactions on Symmetric Cryptology, 2023
The LowMC family of SPN block cipher proposed by Albrecht et al. was designed specifically for MPC-/FHE-/ZKP-friendly use cases. It is especially used as the underlying block cipher of PICNIC, one of the alternate third-round candidate digital signature
