Machine milkability of East Friesian and Lacaune dairy sheep

The Indian Journal of Animal Sciences, 2019
Udder morphology and milking characteristics are one of the factors determining milkability in dairy ewes. Udder morphology traits were measured and subjectively assessed by the use of linear scores in 150 ewes of Lacaune (LC) and East Friesian (EF) dairy breeds.

Study on Growth Performances of R1 Lacaune x Turcana Crossbred Lambs under Highlands Rearing Conditions

Scientific Papers Animal Science and Biotechnologies, 2023
Aim of the current research was to evaluate the effects that back-crossbreeding F1 Lacaune x Turcana ewes with Lacaune rams  has on the growth rates of the R1 progeny under highlands conditions. Researches were carried out at the Sheep and Goats Research

Profitability of a dairy sheep genetic improvement program using artificial insemination [PDF]

, 2010
This simulation study investigated the farm-level economic benefits of a genetic improvement scheme using artificial insemination (AI) with fresh ram semen in dairy sheep of the Chios breed in Greece. Data were collected from 67 farms associated with the

Study on the Effects of Crossbreeding the Turcana Ewes with Lacaune Rams and Performance of F1 Lacaune x Turcana throughout First Lactation

Scientific Papers Animal Science and Biotechnologies, 2023
This paper aimed to compare the milk yield of pure breed Turcana ewes and crossbreed F1 Lacaune x Turcana ewes during their first lactation. Growth performance of F1 Lacaune x Turcana crossbreed lambs and of purebreed Turcana lambs was registered, in ...

Host genetic control on rumen microbiota and its impact on dairy traits in sheep

Genetics Selection Evolution, 2022
Background Milk yield and fine composition in sheep depend on the volatile and long-chain fatty acids, microbial proteins, vitamins produced through feedstuff digestion by the rumen microbiota.

Harnessing microbial metabolism and nutrition to target the gut–mammary axis for better livestock production and health

iMetaOmics, Volume 3, Issue 3, September 2026.
The gut–mammary axis integrates intestinal health with mammary function through neural, endocrine, and immune pathways. Nutritional interventions (probiotics, prebiotics, metabolites) improve gut microecology, generating microbial signals that travel via the axis to the mammary gland. There, they relieve inflammation, enhance milk quality and lactation,

Screening of FecLL prolific allele of the B4GALNT2 gene in Algerian sheep populations

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux
Background: Research on the main genes controlling prolificacy in sheep, also known as fecundity genes (Fec genes), has highlighted the mechanisms involved in ewe fertility and the genetic improvement of prolificacy. The gene, FecL/B4GALNT2 (beta-1,4-N-

Racial susceptibility of sheep to gastrointestinal helminths
Suscetibilidade racial de ovinos a helmintos gastrintestinais

Semina: Ciências Agrárias, 2011
The objective was to compare the susceptibility of sheep breeds Lacaune, Bergamacia, Santa Ines and animals without defined breed (AWDB) kept confined to gastrointestinal helminths. The design used was a randomized block design being considered treatment
