Identification of the SP22 Sperm Protein in Santa Inês and Dorper Rams

Reproduction in Domestic Animals, 2010
The sperm membrane protein referred to as SP22 has been identified in different species and, at least in rats, is highly correlated with fertility. The goals of this study were to identify and to quantify the SP22 protein on spermatozoa from adult rams (Dorper and Santa Inês breeds), and to correlate its levels to morphological and kinematics ...

Estimates of the genetic parameters of a Dorper flock in Brazil

Small Ruminant Research, 2019
Abstract Dorper sheep breeding increased in several countries but the estimates of genetic parameters for some traits remain unknown. Therefore, this study aimed to estimate genetic parameters for body weights at birth (BW), 30 (W30), 60 (W60) and 90 (W90) days of age, total and daily weight gains from 0 to 30 (WG1 and DWG1), 30 to 60 (WG2 and DWG2 ...

Dorper BSI Monitoring with Load Cells and Raspberry PI

2019 IEEE 9th Symposium on Computer Applications & Industrial Electronics (ISCAIE), 2019
The paper describes an alternative method to weigh and monitor the health of livestock via BSI. One method is by recording the measured weight for each livestock for daily weight comparison. The farmer needs to manually lift each of the livestock onto the weighing scale, using rope, producing risk of injury to both farmer and livestock.

Specifika chovu ovcí plemene dorper

2023
The aim of the bachelor thesis was to assess the performance and reproductive indices in the selected breed. The assessment was carried out on a total of 10 dorper lambs, 5 of which were males and 5 females. Each of the animals was weighed and measured for back muscle height at the performance control, in 2021 at 3 months of lambing age and in 2022 at ...

Response of dorper and red Maasai lambs to trickle Haemonchus contortus infections

Research in Veterinary Science, 1996
Six-month-old red Maasai lambs were more resistant than Dorper lambs to repeated infections at one to two week intervals with 1000 Haemonchus contortus infective larvae. Resistance after infection was assessed by means of faecal egg counts, packed cell volumes, eosinophil counts, total serum protein concentrations and mortality rates.

The development of the Dorper, its nutrition and a perspective of the grazing ruminant on veld

Small Ruminant Research, 2000
The development of the non-woolled Dorper sheep breed is briefly reviewed. Despite the large number of Dorpers in South Africa, precious little research results have been published on its nutrition under harsh, arid grazing conditions, especially since this has been an objective for creating and developing the breed.

Energy requirements of Dorper crossbred ewe lambs.

Journal of animal science, 2015
The ME and NE requirements of Dorper crossbred ewe lambs grown from 35 to 50 kg BW were assessed in a comparative slaughter trial. Thirty-five ewe lambs (33.5 ± 0.6 kg BW) of F1 crosses of purebred Dorper and thin-tailed Han sheep were used: 7 lambs were slaughtered at the start of the trial to provide baseline measures of body composition and 7 lambs ...
