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...

Genetic relationships between yield and type traits were investigated using multiple-trait REML procedures with an animal model. Computing strategies were developed to deal with large populations and numbers of traits. Data consisted of records for 3 production and 15 type traits for 20,836 primiparous cows from 1982 to 1988. The model included 2358 herd management effects, 28,749 animal effect...

An epidemiologic study was conducted on 581 dairy cows (indigenous and its crosses 371, exotic crosses 210) of 4 government establishments to find prevalence of udder and teat diseases and their association with udder and teat characteristic, milk yield and milk flow rate in dairy cows. Mastitis (25.5%) was most common disease followed by udder skin diseases (15.0%) and teat diseases (12.6%). P...

Udder Injuries often reduces the milk yield and the sustainability of economic returns. Ultrasonography was deployed to study the nature and number of  stulous tract, which developed as a consequence to mid gestational teat injury in afourth parity Jersey crossbred.Teat ultrasonography revealed the discontinuity of teat wall with a singular  stular tract on the lower one third of the left for...

Binational genetic evaluation between Germany and France were performed for each type trait using a single-trait MACE (multiple across-country evaluation) model. Daughter yield deviations (DYD) of bulls having 30 equivalent daughter contributions or more were the data for parameter estimation. Full pedigree information of bulls was used via sire and dam relationships. In general, across-country...

Objective- The aim of this study was to determine the normal ultrasonographic and morphologic appearance of mammary gland and teat in Caspian mares during lactation and dry period. Design- Experimental study. Animals- Seven mature Caspian mares Procedures- Using a 6.5-8.5 MHz linear transducer the ultrasonographic appearance of lactating and dry mammary glands was determined in 7 mature Casp...

The objective was to examine the direct and correlated responses of linear type, yield traits, and somatic cell scores (SCS) to divergent selection for predicted transmitting ability for type (PTAT) in Holsteins, while maintaining selection for yield traits across lines. For four generations, one-half of the University of Nebraska research Holstein herd was bred to Holstein sires with PTAT > 1....

Udder and teat morphology measurements were taken at approximately 7.5 hr after the a.m. milking for 131 East Friesian (EF) crossbred ewes at an average of 71 d in lactation. Additionally, milking time was recorded for each ewe during two evening and morning milkings. Average daily milk production, milking time, percentage of milk fat, percentage of milk protein, and somatic cell count were 2 L...
