The prevalence of mycobacterial infection among lactating Fulani cows
17 18 The prevalence of mycobacterial infection among lactating Fulani cows was investigated in 19 the Federal Capital Territory (FCT), Abuja and Kaduna State of Nigeria. Tuberculin testing 20 using single comparative intradermal tuberculin test (SCITT) showed a 14.6% positive, 4% 21 doubtful and 81.4% negative reactors. Mycobacterial infection was found to be present in the 22 nomadic (constan...
متن کاملExtended lactation in dairy cows: effects of milking frequency, calving season and nutrition on lactation persistency and milk quality.
Twelve spring-calving and twelve winter-calving cows were managed for extended lactation cycles of 18-months duration, with the former group then completing a second extended lactation. Half of the cows were fed according to standard management practice for the herd; the other half received supplementary concentrate from week 9 of lactation onwards. Commencing at the same time, half of the udde...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Derivation of standard lactation curves for South African dairy cows
Standard Lactation Curves were derived for South African Holstein and Jersey cows, using 20 herd-, 18 ageand six season classes. Six herd classes were below and 13 above the average production level for both breeds. A standard lactation curve was estimated for each combination of herd-, ageand season class, which resulted in 2 160 curves per trait per breed. Variation in Holstein yields was muc...
متن کاملGenetic analysis of lactation persistency in the Polish Holstein-Friesian cows*
The objectives of this study were to analyze the genetic properties of three measures of lactation persistency in Polish Holstein-Friesian cows, and possibly to choose one measure which could be used for estimation of breeding value for lactation persistency in the Polish dairy cattle population. Data included 117,327 first three lactations of 110,141 cows calved in 1995-2009. The lactation cur...
