Our objectives were to examine the effects of added fat in late-gestation cow diets on neonatal response to cold. In Exp. 1, pregnant fall-calving heifers received control (n = 5), safflower seed (n = 5), or whole cottonseed (n = 5) diets. The hay-based, isonitrogenous, and isocaloric diets, fed for 47 d prepartum, contained 1.5, 4.0, and 5.0% fat for control, safflower, and whole cottonseed diets, respectively. At calving, calf BW and vigor score, as well as fat, lactose, and IgG in colostrum… 
SUPPLEMENTAL FAT IN LIMIT-FED, HIGH GRAIN PREPARTUM DIETS OF BEEF COWS: EFFECTS ON COW WEIGHT GAIN, REPRODUCTION, AND CALF HEALTH, IMMUNITY, AND PERFORMANCE
TLDR
Although cow and calf performance was not influenced by prepartum fat supplementation, calf IgG levels and plasma FA associated with immune function were increased in calves from FSUP dams, suggesting prepartu supplemental fat may have positive effects on calf immune status and overall health.
Effect of supplementation fat during the last 3 weeks of uterine life and the preweaning period on performance, ruminal fermentation, blood metabolites, passive immunity and health of the newborn calf
TLDR
Findings support feeding moderate amounts of long-chain PUFA during late uterine life or during the preweaning period have beneficial effects on calf metabolism, growth, and health performance.
Effect of dried corn distillers grains plus solubles compared with soybean hulls, in late gestation heifer diets, on animal and reproductive performance.
TLDR
Prepartum diets containing DDGS, a source of fat and UIP, benefited pregnancy rates in well-maintained, primiparous beef heifers.

TLDR
Although cow and calf performance was not influenced by prepartum fat supplementation, calf IgG levels and plasma FA associated with immune function were increased in calves from FSUP dams, suggesting prepartu supplemental fat may have positive effects on calf immune status and overall health.
Effect of supplementing fat to pregnant nonlactating cows on colostral fatty acid profile and passive immunity of the newborn calf.
TLDR
Apparent efficiency of absorption of IgG was improved in calves born from dams fed fat, and SAT supplementation appeared more effective than supplementation with ESS, and feeding SAT prepartum may be of greater benefit based upon greater circulating IgG concentrations of calves after colostrum feeding.
Effect of pre-calving diet energy content on immunologic and metabolic parameters in the transition cow
TLDR
Dietary treatment had no significant effect on liver triglyceride content on day 1 after calving, days to first ovulation, or plasma NEFA profile after calve, and no statistically significant difference was observed in glucose clearance from the blood or insulin secretion pattern suggesting no difference in tissue sensitivity to insulin was induced by the dietary treatments.
A decade of developments in the area of fat supplementation research with beef cattle and sheep.
TLDR
Manipulating maternal diet to improve unsaturated fatty acid status of the neonate has practical benefits for animals experiencing stress due to exposure to cold environments or conditions which mount an immune response.
Effects of Prepartum Whole Fuzzy Cottonseed or Whole Raw Soybean Supplementation on Response to Timed Artificial Insemination by Suckled Mature Beef Cows Following Ovulation Synchronization1
TLDR
Cows supplemented with whole, fuzzy cottonseed tended to have a greater timed AI pregnancy rate and had a greater final pregnancy rate than cows supplementedWith whole, raw soybeans, and effects of cottonseed and soybean supplementation on response to ovulation synchronization and fixed-time AI by beef cows warrant further study.
Effects of supplemental safflower and vitamin E during late gestation on lamb growth, serum metabolites, and thermogenesis.
TLDR
Based on the decreased body temperature in SSVC lambs at birth, the greater change in BUN during the cold exposure for SS than GC lambs, and the decreased survival rate for SS more than GC Lambs, SSVC-supplemented ewes appeared to give birth to lambs with an apparently decreased energetic capacity.

Effects of feeding beef females supplemental fat during gestation on cold tolerance in newborn calves.
TLDR
It is concluded from Exp. 1 that feeding heifers supplemental fat during late gestation increased glucose concentrations in the newborn calf, resulting in favorable responses in body temperature in the cold-stressed newborns.
Effects of prepartum supplementary fat and muscle hypertrophy genotype on cold tolerance in newborn calves.
TLDR
It is concluded that feeding dams supplemental dietary fat during late gestation increased heat production in newborn calves and potentially could increase calf survival; calves with muscle hypertrophy may have a different ratio of shivering vs nonshivering thermogenesis due to differences in body composition or relationships among uncoupling proteins.
Effects of prepartum protein nutrition and birth weight on basal metabolism in bovine neonates.
TLDR
It is concluded that the thermogenic ability of neonatal calves may be compromised by prepartum protein restriction and(or) small birth weights.
Influence of prepartum nutrition on the reproductive performance of beef females and the performance of their progeny.
TLDR
Two experiments were designed to assess the importance of maternal nutrition in the later stages of gestation on reproductive performance of beef females and on the growth and survival of their calves and there was a tendency for a higher percentage of adequately-fed heifers to show estrus by 40 days postpartum.
Effect of source and amount of supplemental fat on lactation and digestion in cows.
TLDR
Supplementation of a saturated or unsaturated fat source to increase fatty acid content to 7.0% of dietary DM increased milk yield, but a further increase in fat to 9.1% with the saturated source appeared excessive for cows yielding 30 to 35 kg/d of milk.
Effects of supplemental degradable intake protein on utilization of medium- to low-quality forages.
TLDR
Significant variation was observed among forage in the amount of DIP needed to maximize intake and digestion when expressed in relationship to the digestible OM.
Gestation nutrition, tissue exchange and maintenance requirements of heifers.
TLDR
This research indicates that nutritional restriction of beef heifers alters birth weight, repartitions maternal tissues and changes rate of tissue mobilization.
Ruminal metabolism in nonlactating cows fed whole cottonseed or extruded soybeans.
TLDR
The protein from ESB was less degraded in the rumen of cows than protein from WCS, and the unsaturated fatty acids in WCS were not protected from ruminal biohydrogenation, presumably due to mastication of the seed coat.
