Water is a critical nutrient for dairy cows, with intake varying with environment, production, and diet. However, little work has evaluated the effects of water intake on rumen parameters. Using dietary potassium carbonate (K2CO3) as a K supplement to increase water intake, the objective of this study was to evaluate the effect of K2CO3 supplementation on water intake and on rumen parameters of...

the objective of this study was to determine the effect of calcium borogluconate injection 48 and 24 hours prepartum and immediately after parturition on dry matter intake at day of calving, milk yield, incidence of metabolic disorders and uterine conditions during the first 21 days postpartum in cows fed anionic diets. thirty six lactating dairy cows were balanced by parity (1, 2, 3+) and allo...

This study was conducted to determine the relative contribution of feeding behavior, DMI, apparent DM digestibility (DMD), and passage rate on variation in BW gain. One hundred forty-three crossbred steers were used in this study to determine the factors that contribute to variation in BW gain. Steers were 304 ± 1 d of age and had an initial BW of 338 ± 3 kg. Steers had ad libitum access to fee...

this experiment was carried out the aim of the effect of sainfoin forage and forage:concentrate ratios on feed intake, nitrogen balance,ruminal biohydrogenation and milk fatty acid profile in dairy ewes using of eight lori breed ewes according to a replicated 4 × 4 latin square design. treatments were adjusted from one to four according to forage:concentrate ratios of 35:65 with and without sai...

introduction many herbal products (herbs and essential oils) are currently used as feed additives by the feed industry in the european :union: and elsewhere. these phytogenic substances which increase feed aroma or palatability of feeds are classified as sensory additives by european council. however, several publications show that some essential oils may have beneficial effects on animal perfo...

A study was carried out to evaluate nutrient intake and digestibility by West African Dwarf (WAD) sheep fed graded levels of dietary pigeon pea seed meal (PSM). Four diets designated A, B, C and D were formulated to contain 0, 10, 20, and 30% levels of PSM, respectively. Four WAD rams aged between 15 and 17 months and weighing between 16 and 19 kg were used to conduct digestibility study in a 4...

Twenty-four lactating Holstein dairy cows (12 first lactation and 12 multiparous; day in milk = 11 ± 5 days) were allotted to a randomised complete block design in a 2 × 3 factorial with four replicates per treatment to evaluate the effects of two methods of alfalfa feeding (dry and reconstituted to achieve a theoretical dry matter (DM) content of 350 g/kg) and three geometric mean (GM) particl...
