Embodiment 1

[0072] The study evaluated dietary 25-hydroxyvitamin D at 1 mg / d per cow compared to control cows fed a basal diet 3 (25-OH D3).

[0073] 30 lactating Holstein cows (230 kg ± 137 kg body weight on day 1; 8 primiparous) were paired closed (15), mainly by parity and secondarily by milk yield. Cattle were fed the same standard total mixed ration (TMR) in excess twice a day alone. After 2 weeks of acclimatization to this diet, the following treatments were applied to each animal for 10 weeks in a Latin Square design:

[0074] 1. No supplementation (control)

[0075] 2.1mg 25-hydroxyvitamin D 3

[0076] The treatment was applied three times a day in the form of an oral dose (capsules) before milking.

[0077] Raise feed to at least 10x / d. Cows are milked 3 times a day. The number of milking rejections per cow per day was recorded. Milk production was recorded daily. SCC was measured weekly. Monitor DM concentrations in corn silage and rehydrated and ensiled corn grain wee...

Embodiment 2

[0084] Feed formulations for dairy cows can be prepared as follows (on a dry matter basis):

[0085] Element weight% corn silage 45.0 oat hay 4.0 Whole cottonseed 8.3 finely ground ripe corn 14.0 Citrus pomace 8.1 soybean meal 13.5 Low rumen degradability soybean meal (Soypass) 4.0 Vitamin and trace element premixes 1

[0091] 1.5% S

[0092] 10.6% Na

[0093] 7.4% Cl

[0094] ■ 11.5mg / kg of Co

[0095] ■417mg / kg of Cu (as CuSO 4 form)

[0096] ■1165mg / kg of Mn (as MnSO 4 form)

[0097] ■2330mg / kg of Zn (as ZnSO 4 form)

[0098] ■15mg / kg of Se (as Na 2 SeO 3 form)

[0099] ■ 17.5 mg / kg of I (in KI form)

[0100] 116,666 UI / kg of vitamin A

[0101] 33,333 UI / kg of vitamin D

[0102] ■Vitamin E at 833UI / kg

[0103] Mix the ingredients together.

Abstract

Use of one or more vitamin D3 compounds chosen from the group 1-alpha-hydroxy vitamin D3, 25-hydroxy vitamin D3, 1-alpha-,25-dihydroxy vitamin D3, to improve milk quality and / or to increase milk yield of an animal.

Description

technical field [0001] The present invention relates generally to the field of dairy animals. In particular, it relates to a feed supplement composition containing one or more vitamin D selected from the group 3 Compound: 1-alpha-hydroxyvitamin D 3 , 25-Hydroxyvitamin D 3 , 1-α-,25-dihydroxyvitamin D 3 . More specifically, the present invention relates to a feed supplement composition containing the above-mentioned ingredients for improving milk quality and / or increasing milk production of ruminants, especially dairy cows. Background technique [0002] Producing high quality milk is the goal of every dairy farmer. Therefore, the health of animals such as cattle and milk quality and yield are their main concerns. However, infections, such as mastitis, are quite common in cattle. Somatic cell count (SCC) is commonly used as a measure of milk quality. A high SCC is indicative of animal health problems and poor milk quality. The milk market often relies on somatic cell ...
