Title: Application of functional lipids to improve milk production, reproduction and health of dairy cows


1
  • Application of functional lipids to improve milk
    production, reproduction and health of dairy cows

2
The most crucial period--Transition and Early
lactation
mobilization of body tissue
Limited oxidation of fatty acids
Limited export of fatty acid oxidation
Fat accumulation in liver
Increase In disease
Deduction In performance
Decrease In feed intake
Impair on glucose synthesis
Grummer, 1993 Gerloff, 1986 Emery, et al, 1999
NRC, (2001) Overton et al, 1999 Overton
Piepenbrink, 2002
3
Effects of NEB on milk yield, reproduction
health
Negative energy balance
Dry matter intake
Milk yield
Ketosis and fat liver
Reproductive efficiency
Milk fever
Retained palcenta
Displaced abomasum
Economic longevity

Production during peak lactation economic loss
Deduction per day during peak lactation Deduction per a whole lactation of 305 days
1kg Milk yield 200-250 kg milk
Loss of T 500 Loss of T 100,000 125,000

Metabolic disorders and economic loss
Metabolic disorder Economic loss (US) Incidence (Hoards Dairyman) Incidence in 61 highest milking herds in USA
Ketosis 145 5 3.7
Milk fever 334 8 7.2
Displaced abomasum 340 gt3 3.3

BCS loss affects days to 1st ovulation and
conception rate
Bulter Smith (1989)

Effects of rumen bypass fats on production and
reproduction
Rumen bypass fat 2 to 5 of dry matter milk
yield 1,8 to 3,5 kg more milk per day milk fat 2
to 15 improved milk protein 0 6 reduced,
depending on fats protein output unchanged /
increased optimal efficiency 1st 120 days of
lactation conception rate 26 (1st Ser.)/74

Effects of supplemental fats on reproduction (mu
yuyun 2004)

9
Responses of milk yields to supplemental fats

Drackley, 1999
10
Importance of ß-carotene in milk production,
reproduction and health
  • ß-carotene deficiency causes unobvious heat
    ,delayed ovulation,less secretion of progesterone
    ,poor conception, embryo death, etc.
  • ß-carotene supplementation improves cell barrier
    of and immune responses of mummary gland,
    decrease mastitis and somatic cell counts
  • ß-carotene decreases incidence of placental
    retention and metritis
  • Supplementation of ß-carotene increases milk
    yields

11
Feeding ß-carotene in heifers to reduce fertility
disorder incidence
40 black-and white heifers, 56 weeks study

Feeding ?eta-carotene increases fertility of
dairy cows
Reproductive performances of dairy cows
supplemented with beta-carotenes (400 mg/day) for
first 90 days after calving under heat stress

13
Effects of ß-carotene supplements in dairy cows
(Huszenicza 1984)
14
Supplementation of ß-carotene decreases mastitis
and metritis
Frequency of mastitis in the first 3 weeks of
lactation as a function of vitamin A and
ß-carotene supply (Chew, 1985 USA)
Metritis frequency bas a function of vitamin A
and ß-carotene supply (Michal et al,1994)
15
Supplementation of ß-carotene more significantly
decreases somatic cell counts in milk
16
Feeding ?eta-carotene increases milk yields of
dairy cows
Feeding 400 mg/day beta-carotenes after calving
for 60-90 days significantly improved milk yields
of dairy cows at DIM 120
Data are adapted from Rodrigues-Martinez et al.,
2002, J. Dairy Sci. suppl.1. p 306.

Plasma ß-carotene level should be min 3000 ug/l

Vitamin E key functions
  • Biological antioxidant, necessary for cell
    membrane integrity and cell metabolism
  • Regulation of development and function of gonads,
    preparation and protection of pregnancy,
    ,hormone metabolism
  • Stimulation of antibody formation, antitoxic
    action in cellular metabolism
  • Control of glucose metabolism, creatine
    metabolism and glycerol balance

Effects of supplemental Vit E on health after
calving
Supplementation of Vit E at 1000 IU/day decreased
placental retention incidence during last 40 days
of progency(Millet et al, 1990)
Supplementation of Vit E at 1000 IU/day improved
udder shrink during last 40 days of
progency(Millet et al, 1991)
21
Supplemental E improves performances and health
Author Treatment Results
Weiss et al , 1997 Supplementation of Vit E at 1000, 4000 and 2000 IU/day during first 46 dasy , and late 14 days of dry period and after calving, respectively Mastitis of first 7days after calving significantly reduced from 25 to 2.6?
Baldi, et al, 2000 Daily supplement of vitamin E 1000 IU /head during dry period Somastic cell counts in milk reduced and reproduction improved significantly
Wang et al,2004 Daily supplement of vitamin E 300 IU /head Milk yield increased by 1.85 kg

Main rumen inert fat products in the
international markets
  • hydrogenated fat1st generation,
    hydrogenation of animal and vegetable oils
  • CaSFA 2nd generation, calcium salt of fatty
    acids
  • stable fats3rd generation, hydrolyzed and
    fractionated fats
