The discussion of effects of recombinant bovine somatotropin (rbST) administration on the metabolism of lactating dairy cows presented is divided into two parts: short term and long term. Short-term effects are evident during the initial period of treatment when milk production is increased but feed intake has not yet increased. During this period body reserves are mobilized to support the high...

Milk production systems in Eastern Australia vary from grazing improved pastures and fodder crops with strategic use of high energy supplements, to feeding complete diets under feedlot conditions. The nature of the production system within any area is dictated by climatic and economic factors. Economic return from milk production within a given area is a function of the genetic capacity of the ...

To evaluate the effects of physically processed flaxseed [ground flaxseed (GFS) and whole flaxseed(WFS)] as a replacement for extruded soybeans on feed intake, milk production, milk composition, milk fatty acid (FA) composition and blood biochemical parameters, nine primiparus Holstein dairy lactating cowsaveraging 495 ± 34.5 kg of body weight (BW) and 70 ± 5 days in milk (DIM) were assigned in...

Ankyloglossia (tongue tie) is a well-recognized cause of breastfeeding difficulties and, if untreated, can cause maternal nipple pain and trauma, ineffective feeding, and poor infant weight gain. In some cases, this condition will result in a downregulation of the maternal milk supply. Milk-production measurements (24-hour) for a breastfeeding infant with ankyloglossia revealed the ineffective ...

background: aflatoxin m 1 (afm 1 ) is the metabolite of aflatoxin b1 (afb 1 ) and is found in milk when lactating animals are fed with contaminated feedstuff.  the presence of afm 1 in milk, pose a major risk for humans especially kids as it can have immunosuppressive, mutagenic, teratogenic and carcinogenic effects. the present study is aimed to investigate the oc­currence of afm 1 in subsidiz...

BACKGROUND Varying degrees of success have been reported with strategies to increase milk production when lactation is failing. The objective of this study was to investigate the efficacy of domperidone in augmenting milk production in mothers of premature newborns. METHODS Twenty patients were randomly assigned to receive either domperidone or placebo for 7 days. Milk volume was measured dai...

Readily available inexpensive substrate with high product yield is the key to restoring acetone-butanol-ethanol (ABE) fermentation to economic competitiveness. Lactose-replete cheese whey tends to favor the production of butanol over acetone. In the current study, we investigated the fermentability of milk dust powder with high lactose content, for ABE production by Clostridium acetobutylicum a...

the purpose of this study was to investigate the polymorphism of k-casein (k-cn), β-lactoglobulin (b-lg) and leptin (lp) genes in iranian holstein cattle by polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) technique. dna was extracted from blood samples of 139 cows using a modified phenol chloroform method. association between k-cn, b-lg and lp genes’ polymorphism w...

Mastitis is by far the most common and most costly disease in milk production in industrialised countries. Costs are related to loss in milk quality, decreased milk production related to subclinical mastitis, discarded milk, replacement cows, cost of treatment and labour costs [1]. This disease is the most frequent reason for the use of antimicrobials in dairy cows [2]. It can be classified int...

The traits particularly important for milk production include milk yield, protein percentage, fat percentage, and the somatic cell score. Alpha-lactalbumin (α-LA) is an important whey protein of cow milk, and is also present in the milk of many other mammalian species. In this study, we analyzed the genetic polymorphisms of the α-LA gene and their relationship to milk production traits (milk yi...
