Effects of yeast (Saccharomyces cerevisiae) supplementation on intake, digestibility, rumen fermentation and milk yield in Nili-Ravi buffaloes
Rumen Yeast® (RY; Saccharomyces cerevisiae), a live yeast strain, improves milk yield and composition and nutrients digestibility through balancing rumen ecosystem and increasing ruminal cellulolytic bacteria numbers in cattle. To examine the effects of dietary supplementation of RY in Nili-Ravi buffaloes, 16 buffaloes with 8 L average daily milk production were randomly divided into two groups...
متن کاملDefining appropriate model for genetic analysis of milk yield in different lactations of Iranian Holstein cows
In this study, appropriate genetic co (variance) structure across ages of milk production in the Iranian Holstein cows was modeled using 35167 records originated from 1098 sires and 27236 dams. These data were collected from 110 herds during 2011 to 2015 by the Iranian Animal Breeding Center. For all lactations, birth year, birth month, calving year, calving season, calving month, age and herd ...
متن کاملFactors Affecting Prevalence of Bovine Tuberculosis in Nili Ravi Buffaloes
A study was conducted to find out the prevalence of bovine tuberculosis (BTB) in Nili Ravi buffaloes at a livestock experimental station in the Punjab, Pakistan. On the basis of the comparative intradermal tuberculin test (CIDT), prevalence of BTB was found to be 10.06%. Epidemiological factors including old age, high milk production and parity played a significant role in the prevalence of the...
متن کاملRelationship of prepartum udder and teat measurements with subsequent milk production traits in primiparous Nili-Ravi buffaloes
AIM This study was conducted to find out the relationship of prepartum udder and teat measurements with subsequent milk production traits in primiparous Nili-Ravi buffaloes. MATERIALS AND METHODS A total of 12 Nili-Ravi buffalo heifers were selected from Buffalo Farm, Central Institute for Research on Buffaloes, Regional Station- Bir Dosanjh, Nabha, Patiala, Punjab. The udder length (UL), udd...
متن کاملRepeatability of Antral Follicular Count and Its Correlation with Super Stimulation in Nili-ravi Buffaloes
Small ovarian size and low number of follicles are major causes of low reproductive potential in buffalo (Bubalus bubalis). There is no tool through which reproductive performance of buffalo can be phenotyped. Therefore, aim of the present study was to develop a method on the basis of which reproductive performance of buffaloes can be phenotypically assessed. For this purpose two experiments we...
