Fecundity of the Lagune Cow in Benin. Age at first calving and Calving Intervals

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2005
Data collected from 1987 to 2003 at the Samiondji farm in Benin were used to study the age at first calving (n = 200) and calving intervals (n = 805) in the Lagune cow. The age at first calving was 1373 ± 180 days (4 ± 0.5 years) and calving intervals were 426 ± 85 days (14 ± 2.8 months).

Effect of Parity on Productive Performance and Calving Interval in Water Buffaloes

, 2018
The aim of this study was to determine the effect of the parity on productive performance (lactation length, total milk yield and milk yield by day of calving interval) and calving interval in water buffaloes.

Modelling the reproductive efficiency in a beef cow herd: effect of calving date, bull exposure and body condition at calving on the calving–conception interval and calving distribution

, 2008
International audienceA model of reproductive performance was developed to study the influences of breeding management decisions and animal characteristics on the reproductive performance and the calving distribution in a beef herd.

Flow‐pattern evolution of the Scandinavian Ice Sheet indicated by the subglacial lineation record over Norway, Sweden and Finland

Boreas, EarlyView.
We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities

Conservation Biology, EarlyView.
Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Genomic Analysis of Inbreeding Depression on Productive Traits in Rubia Galega Beef Cattle Breed. [PDF]

J Anim Breed Genet
ABSTRACT In autochthonous livestock breeds with small populations, such as the Rubia Galega from Galicia (Spain), mating between relatives is common and can lead to inbreeding depression. Genomic inbreeding coefficients were estimated for 4984 animals using ~63,000 SNPs to assess inbreeding depression in four key traits: age at first calving (AFC) with

Kadar Milk Urea Nitrogen (MUN) pada Sapi Peranakan Friesian Holstein (PFH) Berdasarkan Calving Interval yang Berbeda [PDF]

, 2019
Milk urea nitrogen (MUN) analys may be used as a signal potential problem in feeding program. The aim of this research was to know levels of milk urea nitrogen with different calving interval. This research was using purposive sampling in KUD Tani Wilis,

Informing elephant management through demographic snapshots

Conservation Science and Practice, EarlyView.
Understanding demography is vital for managing species successfully; however, for elephants, traditional surveys are both costly and labor‐intensive. This study presents a cost‐effective method for estimating age structures of savannah elephants in southern Africa, revealing how water provisioning, density dependence, and fertility control influence ...

Genetic relationships between calving date, calving interval, age at first calving and type traits in beef cattle

, 2002
In this paper the genetic relationships between major reproductive traits in beef cattle (Calving Date, Calving Interval and Age at First Calving) and type traits have been estimated to evaluate the usefulness of type classification in predicting ...

Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range
