Effects of grape pomace on growth performance, serum biochemical indices, amino acid composition, and rumen microbial diversity in Dorper × Hu hybrid sheep [PDF]

open access: yesFrontiers in Veterinary Science
IntroductionGrape pomace (GP), a byproduct of wine-making, is rich in nutrients and bioactive compounds. However, its effects on the health and rumen microbial diversity of fattening rams remain insufficiently studied.

Genetic parameter estimates for pre-weaning weight traits in Dorper sheep

open access: yesSmall Ruminant Research, 2001
Genetic parameters were estimated for birth-, 42-day, and 100-day (weaning) weight in the Dorper flock of the Glen Agricultural Institute in South Africa. Direct heritability estimates of 0.11, 0.28 and 0.20 and maternal heritability estimates of 0.10, 0.10 and 0.10 were obtained for body weights at birth, 42 and 100 days, respectively.

On-station comparative analysis of reproductive and survival performance between Red Maasai, Dorper, and Merino sheep breeds

open access: yesAnimal, 2023
The reproductive performance of ewes and the survivability of lambs to weaning have a critical economic impact on sheep farming worldwide. Further, knowledge of major mortality causes allows an opportunity for improved flock management to evade financial

SIMPLE LINEAR AND MULTIPLE REGRESSION ANALYSES OF MORPHOLOGICAL TRAITS ON BODY WEIGHT IN FEMALE DORPER SHEEP LAMBS

open access: yesSiberian Journal of Life Sciences and Agriculture, 2021
Regression is a very influential statistical technique that uses independent variables to describe the dependent variable. The present study was performed to determine the best-fitted model from different regression techniques to predict body weight (BW)

Occurrence and Morphometric Characterization of <i>Cysticercus tenuicollis</i> in Sheep From Minas Gerais, Brazil. [PDF]

open access: yesVet Med Int
In livestock production, the health of slaughtered animals is crucial to ensuring food safety. In this context, animal cysticercosis poses serious problems within production systems. Cysticercosis caused by Cysticercus tenuicollis (larval stage of Taenia hydatigena) is common in pasture‐raised ruminants.

Nutritional Level and Type of Feed on the Reproductive Performance of Ewe and Its Effects on Offspring. [PDF]

open access: yesReprod Domest Anim
ABSTRACT The amount and source of nutrition are important factors that influence an ewe's reproductive ability, but the effects of diet on the reproductive performance of its offspring are unclear. This study aimed to investigate the impact of maternal nutrition (level of nutrition and source) on the reproductive performance of ewes and their female ...

Integrating transcriptome and metabolome to identify key genes regulating important muscular flavour precursors in sheep

open access: yesAnimal, 2022
Flavour precursors are the basis of meat flavour, and their metabolism is regulated by a variety of enzymes. Thus, it is of great significance to identify the key genes related to meat flavour precursors.
