Shamrock Milk Replacer
Shamrock Milk Replacer (20kg)
Shamrock Milk Replacer is a whey based whole milk substitute for calves: calves less than 3 weeks old can only digest and utilise milk derived protein, vegetable protein is not efficiently utilised in younger calves.
The Crude Oils and Fats in Shamrock Milk Replacer are a vital source of energy (2.5 times more energy than carbohydrates), they are important nutrients for maintenance and reduce the risk of hypothermia in the young calf.
Organic acids, antibodies and EMX™ in Shamrock Milk Replacer supports the immune system to reduce the likelihood of scours.
Shamrock Milk Replacer contains high levels of minerals, trace elements and vitamins for the neonate calf to promote growth.
Whole Milk versus Milk Replacer:
A) Growth Rate Performance:
B) Reduced Risk of Scour:
C) Earlier weaning:
D) Health and Biosecurity:
Key Points about Shamrock Milk Replacer (20kg):
What is EMX™:
EMX™: the natural alternative solution to manage protozoan infections such as coccidia and cryptosporidium.
It is original association of plants extracts and essential oils.
Mode of Action:
Essential oil control the outbreak of Eimeria: EMX™ creates local oxidative stress within the gut which impairs membranes of coccidia. The mechanism is the same for all Eimeria species.
Plant extracts improve assimilation of nutrients and contribute to a good balance between host and parasite.
Intestinal Physiology integrity with EMX™:
The increase in HP concentrations (HP is the main protein implicated in inflammation steps) only in the control group may reflect an inflammatory reaction in the intestinal tissues due to the development of the parasite and indicates that the administration of EMX™ may have beneficial effects on the integrity of the intestinal epithelium.
Key Benefits of Shamrock Milk Replacer:
1) Contains 100% whey protein which is most natural and digestible for the calf
2) Enhance immunity to fight off scours and pneumonias
3) EMX™ and Protimax additives included- maintain a healthy digestive tract
4) Reduce scours (nutritional and pathogen-causing scours)
5) Consistent concentration of feed at each feeding- don’t have to rely on milking
6) Good levels of oils and fats for maintenance and to promote appetite for rumen development
7) Can be given once a day- reduce work load
8) Can be used with automatic feeder
9) Biosecurity (eg., Johnes)
√ Can be given to calves from 4 days of age
√ Each 20Kg bag is reconstituted with 160L of 38°C warm water= making up 180L
√ Can be fed twice a day, once a day, cool ad-lib:
Calves on twice a day feeding:
Should receive approx. 2.5- 3 L morning and evening (125g/L)
Therefore, 1 bag would feed approx. 30 calves each day on 6L per day
Calves on once a day feeding:
Suitable from 3 week of age.
Should receive approx. 4 L (170g/litre)
√ Calves should be fed at the same time every day with the same temp and same volume.
√ Easy to mix
√ Stays fresh up to 12 hours after mixing
Evidence based learning about Milk Replacers and Protein Levels:
“Effects of feeding level and protein content of milk replacer on the performance of dairy herd replacements”
-153 high genetic, bull and heifer Holstein
-Friesian calves born between Sept & March
-AIM: heifers reared and bred to calve at 24 months of age
-Calves were allocated to one of four pre-weaning diets:
a) Milk Replacer feeding level 5L/day (reconstituted at a rate of 120 g/l of water)
b) Milk Replacer feeding level 10L/day (reconstituted at a rate of 120 g/l of water)
c) Protein content 21%
d) Protein content 27%
-Introduced pre-weaning diets at 5 days of age and weaned at day 56
Calves offered 10L had signiﬁcantly higher live weight gains than calves fed 5 L MR/day.
No difference in live weight gain were found between calves fed 21% CP & 27%.

Increasing the amount of CP to 22% CP in milk replacers fed to calves at 12% of body weight resulted in increased average daily gains of heart girth, body length, and body weight.

Female calves (n = 108) were assigned to 6 cold milk feeding treatments in two experiments for a 70-day period. Live-weight (LW) was measured weekly, with an additional LW taken at day 410 and post-calving for animals in experiment 1. In Experiment 1, the effect of feeding frequency and age of turnout to pasture on calf performance and 1st lactation milk yields were evaluated. The whole milk (WM) feeding treatments applied were (i) once daily feeding (OD), (ii) twice daily feeding (TD), (iii) OD feeding, outdoors at 38 days (ODO). In Experiment 2, the effects of feeding milk replacer (MR) as opposed to WM and age of turnout to pasture on calf performance were evaluated. The treatments applied were (i) OD feeding with WM (OD), (ii) OD feeding with milk replacer (MR) (ODMR), (iii) OD feeding with MR, outdoors at 38 days (ODMRO). Experiment 1: There were no differences (P > 0.05) in LW or average daily gain between TD and OD calves at day 80 or 410. ODO calves had lower LW at day 80 as compared to OD or TD (P < 0.001). Calf LW at day 80 was 86, 89 and 85 kg and at day 410 was 304, 309 and 316 kg for OD, TD and ODO, respectively. Milk feeding frequency or time of calf turnout had no effect on LW post calving, milk composition or 1st lactation milk yields. Experiment 2: Total LW at day 80 was higher (P < 0.05) for ODMR compared to OD or ODMRO calves. Calf LW was 87, 95, and 88 kg for OD, ODMR and ODMRO, respectively. However, LW at day 410 did not differ between treatments.
This study showed that while some differences were observed in calf LW at day 80, these differences had no effect on LW at day 410 or 1st lactation milk yield. It can be concluded that calves can be successfully reared when fed OD with WM or MR, indoors and when turned out to pasture at 38 days of age.

It has been suggested that United Kingdom recommendations for feeding the neonatal calf (500 g milk replacer (MR)/day; 200-230 g CP/kg milk powder) are inadequate to sustain optimal growth rates in early life. The current study was undertaken with 153 high genetic merit, male and female Holstein-Friesian calves (PIN2000 = £48) born between September and March, with heifers reared and bred to calve at 24 months of age. Calves were allocated to one of four pre-weaning dietary treatments arranged in a 2 MR feeding level (5 v. 10 l/day) × 2 MR protein content (210 v. 270 g CP/kg dry matter (DM)) factorial design. MR was reconstituted at a rate of 120 g/l of water, throughout, and was offered via computerised automated milk feeders. Calves were introduced to pre-weaning diets at 5 days of age and weaned at day 56. During the first 56 days of life, calves offered 10 l MR/day had significantly higher liveweight gains (P < 0.001) than calves fed 5 l MR/day. No significant differences in liveweight gain were found between calves fed 210 g CP/kg DM MR and those fed 270 g CP/kg DM MR from birth to day 56. Differences in live weight and body size due to feeding level disappeared by day 90. Neither MR feeding level nor MR CP content affected age at first service or age at successful service, and with no milk production effects, the results indicate no post-weaning benefits of increased nutrition during the milk-feeding period in dairy heifers.
5. In a study by researchers from the animal science department at the University of Minnesota as well as Milk Products Inc. and Hubbard Feeds (Raeth-Knight et al., 2009), 133 Holstein heifer calves from 3 farms were assigned to 5 treatments beginning at 3 days of age. Calves were fed conventional milk replacer (20% protein, 20% fat, fed at 13.9% solids and 1.25 lbs of powder per day); acidified conventional milk replacer; intensive milk replacer (28% protein, 18% fat, 1.5 lbs of powder per day) fed at 16.7% solids; intensive milk replacer fed at 12.5% solids; or intensive milk replacer fed at 16.7% solids and at an increasing rate. All calves on the first 4 treatments were fed twice daily through 35 days of age; milk replacer was reduced by half and calves were fed once daily from day 36 to weaning at 42 days. Calves on the intensive, high solids, increasing feeding rate treatment were fed 1.5 lbs of powder per day from day 1 to 10 and 2.25 lbs of powder per day from day 11 to 42 in 2 equal feedings. On day 43 milk replacer was reduced by half and fed once daily until weaning at 49 days. All calves were fed free-choice starter; protein in the starter was 20% for conventional calves and 25% for calves fed intensive milk replacer. At 56 days of age calves were moved to group pens and fed grower rations; protein levels were 18% for conventionally fed calves and 21% for intensively fed calves. Diets fed during the later growing period and first lactation were similar across all groups. No mention was made of the breeding protocol used in this study. First lactation records were available for 95 of the animals that began the study. Milk replacer feeding program did not affect first-lactation performance (305-d ME milk yield averaged 28,916 lbs with 3.0% protein and 3.6% fat); however, heifers fed the intensive, high rate program calved almost a month (27.5 days) earlier than those fed conventional milk replacer (P = 0.05)
