- Abstract:
- ... The objectives were to determine the phenotypic correlations between biometric characteristics and obtain predictive functions of vicuña body weight (BW) at shearing. Measurements were recorded in 69 males and 119 females in the area of influence of the Campesino Community of Huachocolpa, Huancavelica region of Peru, during the annual management for the shearing or "chaccu", in 2017. The animals w ...

- Abstract:
- ... We assessed the effect of bentonite and montmorillonite, as sorbents, on feed utilization, lactation performance, and mycotoxin concentrations in milk. During the first week of lactation, fifteen lactating crossbred (Nubian × Baladi) goats weighing 20.5 ± 0.5 kg were randomly assigned to three treatments (five does each) in a complete randomized design for a 90-day trial with repeated measures. Go ...

- Abstract:
- ... This study evaluated the burdens of parasitic protozoans and helminths in dairy goats in two types of farming system in the Czech Republic. We examined nearly 660 faecal samples collected at 14 conventional and 14 organic farms. All farms tested positive for Eimeria oocysts and strongyle-type eggs. The output of coccidial oocysts was highest (86 880 oocysts per gramme - OPG) at an conventional far ...

- Abstract:
- ... Goats are the common grazing livestock integrated into the silvopasture system. Previous grazing studies with goats in southern-pine silvopastures showed significant debarking of pine trees during the cool-season grazing period. However, goats’ behavior in this system during the warm-season grazing period has not been previously reported. The objective of the study was to determine the diurnal beh ...

- Abstract:
- ... Goat production is central to resource-poor rural livelihoods in the tropics. However, it is constrained by high inbreeding levels and poor access to good quality breeding bucks. In this study, semen extenders differing in egg yolk and energy level were compared in their ability to maintain liquid semen from a tropical goat breed, when stored at physiological (37 °C) or refrigerator (4 °C) tempera ...

- Abstract:
- ... Tooth wear can be a considerable factor in shortening the lifespan of herbivores. It is mainly caused by the ingestion of silica particles, either phytoliths - internal to the ingested plants - or external abrasives, such as dust or grit. The avoidance of these abrasives can therefore be favourable to maintain healthy teeth, though it is not known to what extent herbivores are able to select diets ...

Within this protein group, high glycine tyrosine (HGT)-KAP play a crucial role in the definition of their physical-mechanical properties. Polymorphisms in HGT genes have been associated with the variation of different wool traits in sheeps and goats. The Argentine llama is a fiber-producing animal which is v ...

Forty pluriparous Damascus does were synchronized for estrus by double doses of PGF2α, 125 μg each, 10 days apart and were randomly divided into 3 groups. The first group served as control (n = 12), whereas superovulation was induced in the second group (n = 14) by 6 ...
