The implications of spring grazing management on animal liveweight gain, yield and root reserves of lucerne (Medicago sativa L.)
(Lincoln University, 2012)
Lucerne (Medicago sativa L.) is an important legume for New Zealand dryland farms. To ensure the productivity and persistence of lucerne stands rotational grazing is recommended. However, over spring ewes and lambs are ...
An analysis of lambing ewes three times in two years in Southland
(Lincoln University, 1989)
This study examines the management and profitability of three lambings in two years under Southland conditions, and how they
compare with those of a conventional Southland farming system.
There has been little work done ...
Evidence for paternal imprinting of the Beta-3 adrenergic receptor gene and a variant association with reduced twinning rate in New Zealand merino sheep (Ovis aries L.)
(Lincoln University, 2017-11-14)
Reproduction efficiency is key for the productivity and performance of New Zealand sheep farms. Thus improving reproduction efficiency and lamb survival is crucial for improving farm efficiency and profitability. Merino ...
Analysis of the keratin associated protein gene KRTAP6-1 in New Zealand Wiltshire sheep
(Lincoln University, 2016-11-14)
Keratin associated proteins (KAPs) and keratins (Ks) are key elements in the structure of wool fibre and determine the phenotypes seen in sheep. The abundance of the KAP gene family (KRTAP-n) varies in wool fibre. Variation ...
Molecular genetic analysis of IGF1 in Romney sheep and its role in growth
(Lincoln University, 2016-11)
In an effort to improve livestock breeding, recent focus has been on using marker-assisted selection (MAS) to increase the accuracy of the choices made in selecting breeding stock. MAS may increase the annual rate of genetic ...
The influence of mineral nutrition of pasture grasses on the grazing preference by sheep
(Lincoln University, 1993)
This investigation on grazing preference of sheep used two experimental methods; rate of intake by penned sheep and field grazing observations.
Ewe hoggets were fed fresh cut leaf to examine the rate of intake of six ...
The relationship between lean meat yield and birth weight in New Zealand Romney sheep
(Lincoln University, 2017-11-07)
Over recent years sheep numbers in New Zealand have steadily declined due to increased expansion of dairying. This has caused not only reduced ewe breeding flock numbers but also pushed lamb production to less productive ...
Investigation of the molecular genetic basis of fly-strike resistance in NZ sheep: analysis of the FABP4 gene
(Lincoln University, 2013)
Introduction: Fly-strike is a major economic and animal welfare issue in both the New Zealand and Australian sheep industry. There are several factors that predispose sheep to fly-strike, such as fleece-rot, urine staining ...
A bio-economic feasibility study of dairy sheep systems in Canterbury
(Lincoln University, 2014)
This research study outlines the investigative process to determine relevant factors initiating a change from conventional sheep farms to sheep dairy farms on the Canterbury plains and the potential of a sheep milking ...
Optimising a weighing protocol for sheep
(Lincoln University, 2014)
A series of experiments designed to investigate live weight error and analyse the effect fasting and multiple weighing has on live weight measurements were carried out. In the first experiment 24 mixed aged ewes were fasted ...
