1990 journal article
Cholinergic manipulation of digestive function in ruminants and other domestic livestock: A review
Journal of Animal Science, 68(9), 3023.
MeSH headings : Animals; Animals, Domestic / metabolism; Digestion / physiology; Digestive System / drug effects; Digestive System / innervation; Exocrine Glands / innervation; Exocrine Glands / metabolism; Parasympathetic Nervous System / physiology; Parasympathomimetics / pharmacology; Receptors, Muscarinic / physiology; Ruminants / physiology
TL;DR:
Cholinergic stimulation of specific muscarinic receptor subtypes has enhanced secretions of the salivary glands and pancreas and can alter digestive function that may benefit production of cattle and swine.

EFFECTS OF PROTEIN SUPPLEMENTATION AND PARASYMPATHETIC STIMULATION WITH SLAFRAMINE ON UTILIZATION OF LOW QUALITY ROUGHAGE FED TO GOATS AND SHEEP
SMALL RUMINANT RESEARCH, 3(6), 561–573.
TL;DR:
Goats and sheep apparently utilized low quality roughages differently but responded similarly to protein supplementation, and SF was not effective in altering ruminal liquid dilution rate or enhancing nutrient digestibility in goats and sheep fed high fiber diets.

Prostaglandin F-2alpha causes regression of an HCG-induced corpus luteum before day 5 of its lifespan in cattle
Journal of Reproduction & Fertility, 90(1), 245.
MeSH headings : Animals; Cattle; Chorionic Gonadotropin / pharmacology; Corpus Luteum / drug effects; Dinoprost / pharmacology; Estradiol / blood; Estrus / drug effects; Female; Luteolysis / drug effects; Progesterone / blood; Time Factors
TL;DR:
Luteolysis occurred immediately in heifers given PGF-2 alpha on Day 6 of the sham cycle or on Day 12, 14 or 16 of the hCG-treated cycle, with concentration of progesterone in serum decreasing to less than 1 ng/ml within 2 days.

Extension of oestrous cycles and prolonged secretion of progesterone in non-pregnant cattle infused continuously with oxytocin
Journal of Reproduction & Fertility, 90(2), 493.
MeSH headings : Animals; Cattle; Dinoprost / analogs & derivatives; Dinoprost / metabolism; Estradiol / blood; Estradiol / metabolism; Estrus / drug effects; Female; Infusions, Intravenous; Luteolysis / drug effects; Oxytocin / administration & dosage; Oxytocin / pharmacology; Progesterone / blood; Progesterone / metabolism; Secretory Rate / drug effects
TL;DR:
It is concluded that continuous infusion of oxytocin caused extended oestrous cycles, prolonged the secretion of progesterone, and reduced the amplitude of PGFM pulses.

Subclinical ammonia toxicity in steers: Effects on hepatic and portal-drained visceral flux of metabolites and regulatory hormones
Journal of Animal Science, 68(6), 1726.
MeSH headings : Ammonia / blood; Ammonia / toxicity; Animals; Blood Glucose / analysis; Blood Urea Nitrogen; Cattle; Cattle Diseases / chemically induced; Cattle Diseases / metabolism; Fatty Acids, Nonesterified / blood; Glucagon / blood; Glucagon / metabolism; Glucose / metabolism; Insulin / blood; Insulin / metabolism; Lactates / blood; Liver Circulation; Male; Portal System / physiology; Regional Blood Flow
TL;DR:
Results tend to indicate that hyperammonemia reduced hepatic glucose output and glucose-mediated pancreatic insulin release.

Replicate differences in lines of mice selected for body composition
Genome, 33(2), 294.
MeSH headings : Adipose Tissue / anatomy & histology; Animals; Body Composition; Body Weight; Crosses, Genetic; Gene Frequency; Genetic Variation; Hybrid Vigor; Mice; Multivariate Analysis; Phenotype; Selection, Genetic; Statistics as Topic
TL;DR:
Multivariate discriminant function and Mahalanobis distance analysis of selected traits showed that divergence between replicates within selection treatments was much less than among selection treatments.

ENCAPSULATION OF PORCINE SPERMATOZOA IN POLYLYSINE MICROSPHERES
THERIOGENOLOGY, 33(2), 499–508.
TL;DR:
It is demonstrated that porcine spermatozoa can be encapsulated in microspheres and that these capsules can be inseminated into estrous females, but the sperm undergo an accelerated loss of motility in vitro and in vivo.

Correlated responses in body composition based on selection for different indicator traits in mice
Journal of Animal Science, 68(11), 3557.
MeSH headings : Adipose Tissue / anatomy & histology; Animals; Body Composition / genetics; Body Weight / genetics; Breeding; Least-Squares Analysis; Male; Mice / genetics; Models, Biological; Phenotype
TL;DR:
The results indicate that, although there are high positive genetic correlations between fat depots in mice, local control of lipogenesis and lipolysis exists at different sites of fat deposition, and the lack of correlated responses in fat-free percentage of protein (and percentage of ash) suggests that additive genetic variances are low for these traits and the genetic correlations with the selection criteria are low.
