Heat treatments may cause some chemical and physicochemical changes in milk, although milk is a heat-stable system. can different types of milk. This study aimed to compare the effects pasteurization boiling on goat cow milk's macromolecular contents, glutathione levels, superoxide dismutase activities. The protein level both decreased with process, also reduced Both heat activity levels While ...

thirty multiparous holstein dairy cows with average body weights of 687±15 kg and body condition scores of 3.25±0.15 were allocated to 1 out of each 3 groups, immediately after parturition (dim=11) and in a completely randomized design. the first group was fed diet low in rumen undegradable protein (rup; 5.1% of dry matter), the second group fed with medium rup (7.2% of dry matter) while the th...

milk thistle (silybum marianum l. gaertner) is an annual or biannual plant of the asteraceae family. this species is important not only as a medicinal plant traditionally, but also as an endemic plant to protect vegetative and natural resources in iran. this experiment was carried out to find the most effective treatments to break milk thistle seed dormancy and improve its cultivation in vast s...

A 2-yr study investigated effects of different levels of concentrate supplementation on milk production, composition, and lactation curves in pastured dairy goats. For both years, 44 Alpine goats (Capra hircus; 55 +/- 11 kg body weight) were randomly allocated to 4 groups. Animals were supplemented with 0.66 (treatments A and B), 0.33 (treatment C), or 0 kg of concentrate (treatment D) per kg o...

The objective of this study was to investigate the effects of dietary supplementation with raw or heat-treated sunflower oil seed with two levels of 7.5% or 15% on unsaturated fatty acids in milk fat and performances of high-yielding lactating cows. Twenty early lactating Holstein cows were used in a complete randomized design. Treatments included: 1) CON, control (without sunflower oil seed). ...

Metabolizable protein (MP) supply and amino acid balance in the intestine were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources and protected methionine (Met) supplementation. Four ruminallycannulated, multiparous Holstein cows averaging 193±13 days in milk were used in a 4×4 Latin square design to assess N utilization and milk production responses to ...

Eighteen Holstein dairy cows averaging 141 days in milk were used in a complete randomized design to determine the effects of feeding liquid acid whey (LAW) on milk production and composition. Animals received a diet consisting of berseem clover (Trifolium alexandrinum., L), wheat straw and concentrate (Control). Treatments were control and control plus 40 liters/cow/day of LAW. Daily individua...

a total of 240 japanese quail chicks (1 d old) were used in a 42-d trial to study the effects of artichoke leaf powder and vitamin e on growth performance and meat quality. this experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4×2 factorial arrangement with diet and gender as the main effects. four dietary treatments were formulated by a...
