Optimum timing for assessing phenotypic resistance against gastrointestinal nematodes in Pelibuey ewes [PDF]

Helminthologia, 2023
The objective was to identify the optimal stage of production to evaluate the resistance of Pelibuey ewes against gastrointestinal nematodes (GIN). Faecal egg count (FEC) was used to classify the ewes as resistant, sensible or intermediate against GIN ...

Residual Feed Intake and Rumen Metabolism in Growing Pelibuey Sheep. [PDF]

Animals (Basel), 2022
This study was carried out to evaluate the residual feed intake (RFI), volatile fatty acid (VFA) production and enteric methane (CH4) from growing Pelibuey sheep. In this case, 12 non-castrated Pelibuey with an initial average live weight (LW) of 21.17 ± 3.87 kg and an age of 3 months, were housed in individual pens and fed a basal diet with 16% of ...

Glycerol Supplementation During Oestrus Synchronisation With Fluorogestone Acetate Affects Follicular Proliferation, Maturation and Apoptosis of Granulosa Cells in Pelibuey Ewes. [PDF]

Reprod Domest Anim
ABSTRACT This study investigated the impact of glycerol supplementation on the expression of markers associated with follicular proliferation, maturation and apoptosis in Pelibuey ewes synchronised with long (11 days) and short (5 days) protocols using intravaginal fluorogestone acetate (FGA).

Effect of Astragalus mollissimus on Ruminal Fermentation, Methane Production and Performance of Sheep. [PDF]

Vet Med Sci
The effects of A. mollissimus (AM) supplementation on methane (CH4) production, volatile fatty acids, animal performance and nitro compound presence in blood were evaluated through two experiments. Results showed an CH4 reduction by up to 60%. No adverse effects on animal performance and no detectable nitro compound in plasma were reported.

Udder Measurements and Their Relationship with Milk Yield in Pelibuey Ewes. [PDF]

Animals (Basel), 2020
The study aimed to evaluate the relationship between udder measurements and milk yield (MY) in dairy Pelibuey ewes. Udder measurements were taken twice a week for eight weeks before (initial) and after (final) milking, including udder depth (UD), udder circumference (UC), udder width (UW), teat length (TL) and teat diameter (TD) in 38 multiparous ewes.
