GAINPRO® - Rumen Development Of Replacement Heifers (38kb)
RUMEN DEVELOPMENT OF REPLACEMENT HEIFERS
Development of rumen capacity is as important as development of frame and skeletal size in contributing to longterm potential productivity of the dairy animal. The practice of limit-feeding high-energy diets to developing heifers has become more common during periods when the cost of grain is low relative to the cost of forages, especially when considered on the basis of cost per unit of energy. Although feeding a high-concentrate diet can increase rate of gain and feed efficiency, research has shown that feeding a diet higher in forage increases the size and capacity of the rumen relative to the size of the animal (table 1) Hence, even when feeding a forage-based diet does not give the lowest cost of gain, the returns to developing heifers with a forage-based diet will be provided in the long-term productivity of the animal.
SAFE-GUARD® - Brown Stomach Worm - Does It Arrest In Us Dairy Cattle? (51kb)
Producers, veterinarians and others involved in the dairy industry often assume that parasite data generated in beef cattle is fully applicable to dairy cattle. Such assumptions can be costly to dairy producers who seek cost-effective solutions to the problem of worm control. A good example of this difference can be found in research conducted at the University of Kentucky dairy farm. In this two-year study, 50 parasite-naïve tester dairy calves were allowed to graze pastures for one month. Worms picked up during grazing were then recovered from the calves and identified. This method allows for determination of the type and size of the worm population present on contaminated pasture. In this study, Nematodirus was the most common worm found with an average of 2,220 worms per calf. Cooperia was the second most common worm found (2,018 worms). Brown stomach worm was third (846 worms ). No population of arrested brown stomach worm was found. These results were surprising because the study had been conducted to determine the seasonal pattern of arrested development for brown stomach worm!
SAFE-GUARD® - Deworming Lactating Dairy Cows During The Transition Period (50kb)
Deworming lactating dairy cows is a venture beyond treating disease. Although most dairy cows have sufficient immunity such that parasitic disease will not occur, they’re not immune from production losses caused by parasite exposure and the subsequent development of infection. Internal parasites interfere with efficient production and, therefore, the strategic deworming of lactating dairy cows is designed to prevent production losses caused by these parasites. Whole-herd deworming in late fall or early winter is a good strategy to maintain a parasite-free herd throughout the winter months in northern climates; however, a separate strategy for spring and summer to control internal parasites is required. During this period, individual animal treatment provides the very best control if production losses are to be prevented. Management may find, when feeding transitional groups in freestalls, deworming the cows via the feed (TMR) is cost-effective and laborsaving.

NEOGUARD™ - Neoguard™ Technical Information Sheet (73kb)
NeoGuard™ is the first and only USDA-approved safe and efficacious vaccine used as an aid in the reduction of abortions caused by Neospora caninum.
NEOGUARD™ - Neoguard™ Technical Bulletin 1 (53kb)
- Seven hundred fifty-seven cows from seven farms were used in the study.
- The herds used had no previous history of reproductive problems.
- Vaccinates received two injections of Neospora caninum vaccine 21 to 28 days apart.
- Controls received two injections of saline at the same interval.
- Cattle were pregnancy tested by palpation 60 to 90 days following the second vaccination.
- The Neospora caninum vaccine is safe for use in healthy, pregnant dairy cattle.
- Injection site reactions were insignificant or similar to those seen with other vaccines.
NEOGUARD™ - Neoguard™ Technical Bulletin 2 (63kb)
- Thirty-eight pregnant heifers 18 to 24 months of age were used in the study.
Treatments were as follows:
1. Control – non-vaccinates and
2. NeoGuard™, Neospora caninum vaccine, 5 mL given subcutaneously, two injections, 21 days apart.
- All heifers used in the study tested serum-negative for Neospora caninum antibodies at the beginning of the study.
- NeoGuard™ was given on days 56 and 77 of gestation.
- All heifers were challenged with a Neospora caninum challenge preparation on day 95 of gestation.
- NeoGuard™ vaccinated heifers had an increase (Pd0.05) in sample to positive (S/P) ratios at the time of challenge and 28 days post-challenge when compared to control heifers indicating a marked immunological response to the vaccination.
- NeoGuard™ vaccinated heifers had fewer (P<0.05) abortions than control heifers.
- NeoGuard™ is efficacious and safe when used in healthy, pregnant heifers as an aid in reducing abortions in cattle exposed to a challenge of Neospora caninum.
