OBJECTIVE Human milk provides neonates with a meaningful degree of protection from infection, but the responsible mechanisms are not well understood. Discovering these mechanisms is important, because of the possibility of supplementing infant formulas with factors that simulate human milk's protective capacity. We postulated that granulocyte colony-stimulating factor (G-CSF), a cytokine known ...

In a double blind crossover study 10 children with infantile colic were fed breast milk and cow's milk formula, untreated and treated with lactase. Colic was present on 71% of breast milk and 89% of cow's milk days. Daily duration and severity of colic did not differ for milk preparations.

Rabbit dams fed 0.1% BSA for various periods before and during lactation produced anti-BSA of low avidity and IgG isotype in serum and milk. Milk anti-BSA and IgG concentrations were one-third to one-half of those in the serum. At birth, kits had IgG and anti-BSA serum concentrations approximately equal to their dams. Both fell rapidly for the first 10-20 days, levelling off at about 1 mg IgG/m...

abstract background: as any delay in the onset of milk production and ejection in the first few days after delivery can cause breast-feeding failure, this study has been done to determine factors that may affect the onset time of lactation in vaginal and cesarean section deliveries with and without labor pain (elective). methods: 300 partujient mothers selected from two private and university h...

Mammalian newborns exhibit avid responsiveness to odor compounds emanating from conspecific milk. Milk is however developmentally heterogeneous in composition as a function of both evolved constraints and offspring demand. The present study aimed to verify whether milk odor attractivity for neonates is equally distributed along lactation in Mus musculus (Balb-c strain). Therefore, we exposed pu...

Objective-  To study the effect of digit amputation on animal survival, and distribution of   lesions on limbs, days in milk and parity in operated cows.   Design- Retrospective descriptive study.   Animals- Thirteen cows in a dairy herd consisting 1100 lactating Holstein cows.   Procedures- Digit amputation by using a loop wire after inducing local intravenous anesthesia. Results- Digits of ...

the aim of this study was to evaluate the effect of replacing progesterone injections by progesterone vaginal inserts on productive and reproductive parameters of lactating cows with reproductive problems after prolonged periods of heat stress. fifteen holstein cows were randomly assigned to one of three treatments: 1) treated with two progesterone vaginal inserts (p4-ins); 2) treated with prog...

Introduction: Zinc plays a vital role in various biological functions and physical growth. More than 300 enzymes in body need zinc for proper function. In this study, the concentration of the zinc micronutrient in breast milk was evaluated and analyzed at the first month of breastfeeding. Materials and Methods: This was a descriptive study of 150 breastfeeding mothers in the 2014 who had given...

Forty-eight primiparous and pregnant Holstein cows at 202 (+/-59) days in milk and average daily milk production (DMP) of 22 (+/-5.3) kg at the beginning of the trial were used to study the possibility of identifying animals that are more responsive to recombinant bovine somatotropin (rbST). Animals were housed in free-stall barns, milked three times a day and fed a total mixed ration. Animals ...

Data containing 14,188 lactation and reproductive records of Korean Holstein cows at first parity distributed across 3734 herd-year-season groups were analyzed to get genetic (co)variance estimates for milk yield, fat yield, calving ease, and days open. Milk and Fat yields were adjusted to 305 d. Heritabilities and genetic correlations were estimated in two different animal models on which were...
