Tea waste (TW) has a protein content of approximately 30% and the potential to replace other sources. However, effect dietary TW supplement is still ambiguous. The objective this study was investigate three levels on performances physiological changes in goats. Nine multiparous crossbred Saanen lactating goats were arranged replicates 3 × Latin square. groups fed with 0, 5, or 10 by weight [wt%...

Heat stress is detrimental during gestation; however, the effects of heat on goat placental characteristics and kid survival remain unclear. The objective this study was to evaluate at final gestation cortisol concentration, placenta characteristics, expression genes related placenta. Forty-six primiparous multiparous Saanen goats were subjected control (CT; under a thermoneutral environment: a...

The Slovenian karst region and similar types of land are difficult to cultivate and often exposed to the process of being abandoned and overgrown with shrubs, trees, and brushwood. Co-grazing in a mixed group may be a way to optimize the management of sheep and goat flocks in such areas. To obtain more knowledge of the natural behavior of small ruminants, the experiment was designed on pasture ...

Ovarian cyclicity in the goat continues under short days (8L: 16D), while it ceases for 150-200 days under long days (16L: 8D). During the anovulatory period under long days, prolactin secretion is enhanced. Experiments were conducted to investigate the role of the pineal gland in the photoperiodic control of the gonadal function and prolactin secretion in the goat. Firstly, the effects of the ...

β-lactoglobulin (BLG), a dominant allergen in goat milk, is difficult to remove by traditional biochemical methods. Its elimination from goat milk by genetic modification therefore poses a major challenge for modern goat breeders. A shRNA targeting BLG mRNA with high interference efficiency was identified, with which lentiviral vectors were used for mediating stable shRNA interference in goat-f...

To investigate the genetic diversity of seven Chinese indigenous meat goat breeds (Tibet goat, Guizhou white goat, Shannan white goat, Yichang white goat, Matou goat, Changjiangsanjiaozhou white goat and Anhui white goat), explain their genetic relationship and assess their integrity and degree of admixture, 302 individuals from these breeds and 42 Boer goats introduced from Africa as reference...

The beneficial effects of polyphenol intake such as improved nitrogen retention make them interesting feed supplements for ruminants. In contrast, dietary polyphenols may have adverse on the bioavailability nutrients and palatability which might impair growth performance. differ between different ruminant species well direct metabolites via suckling when supplemented to lactating dams. This stu...

The aim of this study is a further characterization of the electrical conductivity (EC) signal of goat milk, acquired on-line by EC sensors, to identify new indexes representative of the EC variations that can be observed during milking, when considering not healthy (NH) glands. Two foremilk gland samples from 42 Saanen goats, were collected for three consecutive weeks and for three different l...
