Although it is still most common to rear dairy calves separately from adult cattle, the interest in prolonged contact between and lactating cows during early life increasing. Previous research has documented positive effects of cow-calf (CCC) on for example calf growth udder health suckled cows, but also negative such as increased separation distress reduced weight gains after weaning. The aim this study was use information European farms with identify innovative solutions challenges CCC...
Haplotypes with reduced or missing homozygosity may harbor deleterious alleles that compromise juvenile survival. A scan for homozygous haplotype deficiency revealed a short segment on bovine chromosome 19 (Braunvieh 2, BH2) was associated high mortality in Braunvieh cattle. However, the molecular genetic underpinnings and pathophysiology of BH2 remain to be elucidated.The frequency 6.5 % 8,446 animals from national genome databases. Both perinatal calves were higher than average cattle...
The optimal utilization of forages is crucial in cattle production, especially organic dairy systems that encourage forage-based feeding with limited concentrate amounts. Reduction the particle size known to improve feed intake and thus might be a viable option help cows cope less nutrient-dense feeds. main aim this study was evaluate effects reducing forage geometric mean 52 mm (conventional size; CON) 7 (reduced RED) high-forage diet (80% dry matter) on cows' sorting behavior, intake,...
This study aimed to develop a tool detect mildly lame cows by combining already existing data from sensors, AMSs, and routinely recorded animal farm data. For this purpose, ten dairy farms were visited every 30–42 days January 2020 May 2021. Locomotion scores (LCS, one for nonlame five severely lame) body condition (BCS) assessed at each visit, resulting in total of 594 animals. A questionnaire about management husbandry was completed the inclusion potential risk factors. lameness incidence...
Genetic parameters were estimated for semen production traits collected in an Austrian AI centre the years 2000-2004. In total, 12,746 ejaculates from 301 dual-purpose Simmental (Fleckvieh) bulls examined considering different effects on ejaculate volume, sperm concentration, percentage of viable spermatozoa ejaculate, total per and motility. The model genetic parameter estimation included fixed age bull, collection interval, number collections day, bull handler, collector, year month...
Abstract. The proportional hazards method was used to estimate breeding values for functional length of productive life within the endangered Slovak Pinzgau population. analyzed data set contained 21,985 cows, daughters 254 sires. risk culling higher cows with lower milk production relative herd average, age at first calving and in herds decreasing size. In lactation highest beginning, decreased during lactation. From second onwards an increasing observed. effect breed composition found...
In order to establish a total merit index, the relative economic values of traits considered must be known. Hence, objective this study was derive values, defined by value one unit superiority trait, for essential in dairy sheep based on herd model. These included (milk carrier = water, lactose and mineral nutrients, fat protein yield), fattening (daily gain, dressing percentage, EUROP grading score) functional (stillbirth rate, losses until first mating, litter size, lambing interval,...
Lactose is a sugar uniquely found in mammals' milk and it the major solid bovines. yield (LY, kg/d) responsible for volume, whereas lactose percentage (LP) thought to be more related epithelial integrity thus udder health. There paucity of studies that have investigated at genomic level dairy cows. This paper aimed improve our knowledge on LP LY, providing new insights into significant regions affecting these traits. A genome-wide association study LY was carried out Fleckvieh cattle by...
In recent decades, a general increase in multiple birth (MB) rate has been reported both dairy and dual-purpose cattle breeds. As there is evidence that MB negative effects on economically important traits cows, the aims of this study were to (i) investigate environmental genetic factors affecting (ii) assess impact productive nonproductive Austrian breeds Pinzgauer Tyrol Grey. The dataset included 99,141 calvings 33,791 68,454 19,244 Grey cows recorded from 2000 2022. Environmental...
Using pedigree data, the inbreeding coefficients of 715 Austrian dual-purpose Simmental (Fleckvieh) bulls stationed in two artificial insemination (AI) centres Upper and Lower Austria were calculated incorporated statistical models for analysis semen quality. Five quality parameters (volume, concentration, motility, number spermatozoa per ejaculate percentage viable spermatozoa) approximately 30,000 ejaculates, used separate data sets, investigated. The mixed model included fixed effects age...
