BACKGROUND The incidence of necrotizing enterocolitis (NEC) and possibly also of sepsis is lower in preterm infants fed their own mother's milk (hereafter 'mother's milk') compared with formula-fed infants. It is unclear whether this is caused by the protective properties of breast milk or by the absence of cow's milk. Especially in early life, mother's milk is often unavailable to preterm infa...

OBJECTIVES Because inadequate expression of human milk (EBM) in mothers of hospitalized infants were noticed in a neonatal center of our hospital, family education program was carried out to increase the EBM. METHODS A breast milk pumping diary was introduced to the mothers with preterm infant(s) admitted in the NICU. The ratios of EBM (days of EBM to NICU/hospitalized days), breast milk feed...

The objective of the present study was to determine the effects of rumen-protected choline (RPC) supplementation on body condition, milk production and milk choline content during the periparturient period. Thirty-two Holstein cows were allocated into two groups (RPC group - with RPC supplementation, and control group - without RPC supplementation) 28 days before the expected calving. Cows were...

the present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (dap) in the mineral mixt...

the objective fllowed in the present study was to evaluate the effects of different milkingfrequencies on milk production and on blood metabolites in holstein cows. sixty-six fresh holsteincows were allocated to two treatments namely: 4 (4x) vs. 6 times (6x) of daily milking, during the first3 months of lactation, and then switching on to a three times of daily milking until end of the lactatio...

tetracyclines (tcs) are broad-spectrum antibiotics that are used widely in veterinary medicine. the present study was carried out to trace the residues of oxytetracycline (otc) and tetracycline (tc) in pasteurized milk that is marketed in tehran with the use of a high performance liquid chromatography (hplc). ninety milk samples were collected during five sequential days from the products of si...

Animals with the same lactation breeding value can have different shapes of additive genetic curve, implying differences in persistency lactation. Since environmental conditions change across lactation, animals re-rank through leading to genotype by environment interaction for daily milk yield. The objectives this project is describe curve pattern estimated values and assess extent sire cow re-...
