Age of cow and age of dam effects on milk production of Hereford cows
Journal of Animal Science, 67(10), 2544.
MeSH headings : Age Factors; Animals; Birth Weight; Cattle / physiology; Female; Lactation; Pregnancy; Regression Analysis; Weaning
TL;DR:
It appears that age of dam should be considered in evaluation of cow performance, as a lasting detrimental effect of older cows on lactation yield of daughters is suggested.

EFFECT OF OVIDUCTAL CONDITION ON THE DEVELOPMENT OF ONE-CELL PORCINE EMBRYOS IN MOUSE OR RAT OVIDUCTS MAINTAINED IN ORGAN-CULTURE
THERIOGENOLOGY, 32(6), 885–891.
TL;DR:
One-cell porcine embryo development was supported to a greater extent in mouse oviducts obtained from females mated to fertile or vasectomized males and not flushed, and cell numbers were similar for embryos reaching the morula or blastocyst stage across all treatments.

MeSH headings : Animals; Blastocyst / physiology; Cell Count; Culture Media; Fallopian Tubes / physiology; Female; Mice; Organ Culture Techniques; Pregnancy; Swine / embryology
TL;DR:
The procedure described for mouse oviduct organ culture provides a simple method for culturing early-stage pig embryos to the morula or blastocyst stage prior to embryo transfer.

A RECESSIVE MUTATION CAUSING IMPERFORATE VAGINA IN MICE
JOURNAL OF HEREDITY, Vol. 80, pp. 478–482.
MeSH headings : Animals; Crosses, Genetic; Female; Genes, Recessive; Male; Mice; Mice, Mutant Strains / genetics; Phenotype; Random Allocation; Vaginal Diseases / genetics; Vaginal Diseases / pathology; Vaginal Diseases / veterinary
TL;DR:
A recessive mutation (ipv) causing imperforate vagina was discovered in a line of mice selected for low lean tissue mass as a proportion of body weight, and two full sisters were found to have marked swelling of the perineum and complete closure of the vagina.

A PRAGMATIC APPROACH TO IMPROVING SMALL RUMINANT DIETS IN THE INDONESIAN HUMID TROPICS
JOURNAL OF ANIMAL SCIENCE, 67(11), 3068–3079.
MeSH headings : Animal Feed; Animal Nutritional Physiological Phenomena; Animals; Fertility; Goats / growth & development; Goats / physiology; Indonesia; Sheep / growth & development; Sheep / physiology; Tropical Climate
TL;DR:
These experiments show that economically effective options exist for improving small ruminant diets in the humid tropics and that Reproductive performance of North Sumatran ewes grazing a native pasture under rubber trees also was improved with supplementation.

THE USEFULNESS OF SELECTION FOR YIELD AND FUNCTIONAL TYPE TRAITS
JOURNAL OF DAIRY SCIENCE, 72(1), 187–193.
TL;DR:
Udder depth, teat placement, foot angle, and milk yield measured in first lactation were evaluated in an index to improve a breeding goal consisting of milk yield and involuntary culling and predicted response was insensitive to small changes in heritability for voluntary culling or changes in genetic correlations between milk and type traits.
