Relationships between weaning weight, maternal weaning weight, and milk production in polled Hereford cattle [PDF]

Kansas Agricultural Experiment Station Research Reports, 1995
Performance data from a Polled Hereford herd selected for improved feed conversion were used to calculate a variety of genetic parameters. Heritabilities were .14 for weaning wt, .18 for maternal weaning wt., and .19 for milk production.

Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

Adjustment factors for lamb weaning weight [PDF]

New Zealand Journal of Agricultural Research, 1979
Abstract Sources of variation in adjustment factors for weaning weight of New Zealand Romney lambs were studied. Data from 12 flocks and 6 years were used. Adjustment factors for sex differences were affected significantly by flock, year, and interactions between flock and year.

Evaluation of growth parameters and body condition score on weaning stages of Saanen goats

Journal of Advanced Veterinary and Animal Research, 2022
Objective: There are three objectives in this study; 1) to measure the live weight of pre-and post-weaning Saanen kids; 2) to determine the growth curves between males and females pre-and post-weaning Saanen kids; and 3) to analyze the body condition ...

Effect of piglet birth weight on weights at weaning and 42 days post weaning

Journal of Swine Health and Production, 2007
Objective: To model the effects of birth weight on preweaning survival and weights at weaning and at 42 days post weaning. Materials and methods: Individual birth-weight and weaning-weight records of 2467 pigs weaned at 14 to 21 days old were partitioned into nine categories incrementally increasing or decreasing by 0.5 SD (0.16 and 0.68 kg ...

Development of selection strategies for genetic improvement in production traits of Mecheri sheep based on a Bayesian multi trait evaluation.

PLoS ONE, 2023
The progression of genetic selection techniques to enhance farm animal performance traits is guided by the present level of genetic variation and maternal impact in each trait, as well as the genetic association between traits.

Postweaning growth and feeding behaviour in pigs: effect of heavier hybrid and weaning intact litters in farrowing pens for loose-housed sows

Animal, 2023
Abrupt weaning of four-week-old pigs is associated with multiple stressors. Housing pigs in intact litters is a way to reduce the stress associated with moving and mixing of unfamiliar pigs. Furthermore, higher weaning weight may improve pigs’ robustness

Increasing weaning age of piglets from 4 to 7 weeks reduces stress, increases post-weaning feed intake but does not improve intestinal functionality [PDF]

, 2010
This study tested the hypothesis that late weaning and the availability of creep feed during the suckling period compared with early weaning, improves feed intake, decreases stress and improves the integrity of the intestinal tract.
