Effects of Incremental Dietary Levels of Ground Flaxseed on Milk Production, Ruminal Metabolism, and Enteric Methane Emissions in Organic Dairy Cows [PDF]
, 2012 Ground Flaxseed (Linum uitatissimum) is a lipid supplement that is commonly fed to dairy cows. It is believed that supplemental lipid can change the Fatty Acid (FA) composition in the milk, and decrease methane production. Twenty lactating organic Jersey

Somatic Cell Score as Predictor of Daily Milk Yield in Holsteins
Journal of Agricultural and Marine Sciences [JAMS], 1998 The purpose of our Study was to determine if variation in milk yield at later Stages of lactation can be explained by expressions of early lactation somatic cell score (SCS) and if the prediction of future yield within lactation can be improved by including SCS among the predictors. Three data sets (n >600.000 each) were: milk yield with sample days

Cold markedly influences milk yield of Sardinian dairy sheep farms [PDF]
, 2007 The effects of cold stress on milk production have been widely examined in cattle and goats but little studied in dairy sheep. For this reason, the milk production of 10 dairy sheep farms, located throughout the Sardinian island, was analysed in ...

Genetic variability detected at the lactoferrin locus (LTF) in the Italian Mediterranean river buffalo [PDF]
, 2016 Lactoferrin (LTF) is multi-functional protein belonging to the whey protein fractions of the milk. The gene LTF encoding for such protein is considered a potential candidate for body measurement, milk composition and yield.

Profitability and milk yield response to protein supplementation in mid-lactation dairy cows. [PDF]
, 2009 This study utilized 120 Holstein-Friesian dairy cows in mid-lactation in a randomized block experimental design. The aim was to evaluate milk yield and composition responses to protein supplementation and profitability over an eight-week lactation period.

Relationship between Daily Milk Yield and Suckling Behavior in Beef Cattle
Nihon Chikusan Gakkaiho, 1989 肉用牛における乳量と吸乳行動の関係を明らかにするため,黒毛和種67組と無角和種10組の母•子牛を用いて,分娩後10,30,60,90,180日における1日当たりの乳量(1日乳量)と吸乳行動を調査した.1日乳量と1日当たりの吸乳回数(NSD)の関係は,黒毛和種においては各測定日とも相関係数が負であり,30,60日齢では,有意な相関が認められた.黒毛和種における1日乳量と1日当たりの吸乳時間(DSD)との関係は,NSDと同様に,1日乳量が増加するのに伴いDSDが短くなる傾向にあった.30,60日齢では有意な相関が認められた.無角和種では10日で乳量の増加に伴うDSDの短縮が認められた.1日乳量と1回当たりの吸乳時間(DSB)との関係は黒毛和種では認められなかったが ...
