The objectives of this study were to measure particle size and evaluate the effect of increasing alfalfa hay particle size on production characteristics in lactating Holstein dairy cows. Ninety multiparous Holstein cows in early to mid-lactation were randomly assigned in a complete randomized design for a 30-day period. Animals were offered one of the three diets, which were identical in energy...

The objectives of our study were to determine the effects altering dietary ratio palmitic (C16:0) and oleic (cis-9 C18:1) acids on production metabolic responses early-lactation dairy cows during immediate postpartum period evaluate carryover treatment diets early in lactation. Fifty-six multiparous used a randomized complete block design randomly assigned 1 4 treatments (14 per treatment) fed ...

this study was conducted to evaluate production response of early lactating cows to rumen protected fats. twelve (nine multiparous and three primiparous) holstein cows (26±4 d in milk) were empolyed in a replicated 3×3 latin square design of 21-d periods. each period consisted of 14 days of adaptation and 7 days of sampling. cows received diets containing either one of two types of protected fa...

A 70-day feeding trial was performed to assess the effect of a mixture functional feed supplements (FFS; contains encapsulated cinnamaldehyde, condensed tannins, capsaicin, piperine, and curcumin) during mid-lactation on milk production composition, intake, blood profile multiparous dairy cows. Sixty Holstein cows (116.1 ± 17.1 days in milk, 606 9.3 kg BW, 45.73 6.7 kg/d production) were distri...

Forty Holstein dairy cows in their first and second lactation were used in a lactation study from 4-week prepartum through 14-week postpartum to investigate the potential effect of feeding different levels of ruminally protected methionine and choline on milk yield persistency of Holstein dairy cows. Cows were randomly assigned to receive one of the following treatments: 18 g/d of rumen-protect...

The objective of this study was to determine lactation performance by dairy cows fed corn snaplage either alone (SNAP) or in combination with ground dry shelled corn (SPDC) versus rolled high-moisture shelled corn (RHMC). Dry-matter content was greater for RHMC (78.2%) than SNAP (68.5%). The starch content of SNAP was approximately 10%-units lower than RHMC. Sixty Holstein cows (30 primiparous ...

This study aims to determine the effect of partial (50% and 75%) complete (100%) replacement barley corn silage with whole plant faba bean on milk production, feed intake efficiency, digestibility, rumen fermentation characteristics high producing cows. A repeated 4 × Latin square (early lactating cows: four cannulated non-cannulated) design was used. The used for treatments were different: con...
