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

2 The most crucial period--Transition and Early lactation Fat accumulation in liver mobilization of body tissue Limited oxidation of fatty acids Limited export of fatty acid oxidation Decrease In feed intake Impair on glucose synthesis Deduction In performance Increase In disease 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 Dry matter intake Negative energy balance Milk yield Displaced abomasum Milk fever Ketosis and fat liver Reproductive efficiency Economic longevity Retained palcenta

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

5 Metabolic disorders and economic loss Metabolic disorder Economic loss (US$) Incidence (Hoards Dairyman) Incidence in 61 highest milking herds in USA Ketosis1455%3.7% Milk fever3348%7.2% Displaced abomasum 340>3%3.3% Placental retention %9.0%

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

7 Effects of rumen bypass fats on production and reproduction Rumen bypass fat2 to 5 % of dry matter milk yield1,8 to 3,5 kg more milk per day milk fat2 to 15% improved milk protein0~ 6% reduced, depending on fats protein outputunchanged / increased optimal efficiency1 st 120 days of lactation conception rate+ 26% (1st Ser.)/+74% (2nd Ser.) pregnancy rate+27% open daysless 6.8 days AI per conception- 0.4 service

8 Effects of supplemental fats on reproduction (mu yuyun 2004)

9 Responses of milk yields to supplemental fats Drackley, 1999

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

11 Heifer cowsWith β-carotene ( 0.3 mg β-carotene IU Vit A/Kg B.W./day) Without β-carotene ( 220 IU vit A/kg B.W./day) P Luteal cysts, %030 <0.01 Follicular cysts, %510 >0.05 Conception rate, % After 1 st insemination After 2 nd insemination <0.01 <0.05 Nos. of insemination per head <0.05 Lotthammer, Ahlswede, and Meyer (1976) 40 black-and white heifers, 56 weeks study Feeding β-carotene in heifers to reduce fertility disorder incidence

12 Reproductive performances of dairy cows supplemented with beta-carotenes (400 mg/day) for first 90 days after calving under heat stress Multiparous cowsControlβ-carotene Days-open Pregnancy rate, %4859 Data are adapted from Rodrigues-Martinez et al., 2002, J. Dairy Sci. suppl.1. p 306. Feeding Βeta-carotene increases fertility of dairy cows

13 Effects of β-carotene supplements in dairy cows ( Huszenicza 1984)

14 Frequency of mastitis in the first 3 weeks of lactation as a function of vitamin A and β- carotene supply (Chew, 1985 USA) Metritis frequency bas a function of vitamin A and β-carotene supply Michal et al 1994) Supplementation of β-carotene decreases mastitis and metritis

15 Supplementation of β-carotene more significantly decreases somatic cell counts in milk

16 Data are adapted from Rodrigues-Martinez et al., 2002, J. Dairy Sci. suppl.1. p 306. Feeding 400 mg/day beta-carotenes after calving for days significantly improved milk yields of dairy cows at DIM 120 Feeding Βeta-carotene increases milk yields of dairy cows

17 Plasma β-carotene level should be min 3000 ug/l

18 Maintenance : min. 100 mg /day Gestation: min. 200 mg /day Lactation: mg /kg milk yield Requirements of Βeta-carotene in dairy cows Ruiter, 1998 Transition period : min. 600 mg /day Lactation: min. 300 mg/day BASF, 1998

19 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 Antioxidation model of Vitmin E

20 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 AuthorTreatmentResults 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 Supplemental E improves performances and health
