Multi-attribute decision-making: Use of scoring methods to choose the best form of dietary fat supplement in pregnant Saanen goats.

Background: Nutritional manipulation with functional nutrients like polyunsaturated fatty acids can boost milk production efficiency in dairy farming. It is important to consider the animal's physiological periods, especially the second half of the first pregnancy for mammary gland development.

Objectives: By considering multiple factors and comparing them, multi-attribute decision-making (MADM) can be utilized to conduct further assessments and select the best diet for the animals.

Changes in the gene expression profile of the mammary gland lipogenic enzymes in Saanen goats in response to dietary fats.

Background: The second half of the first pregnancy is a critical period in the growth and development of the mammary gland. The use of functional compounds during this period may positively impact livestock performance.

Objectives: In this study, changes in lipogenic enzyme gene expression in the mammary gland of Saanen goats in response to different dietary fat sources were analysed.

Effects of supplementation of tris-egg yolk extender with different sugars and antioxidants on freezability of ram semen.

This study was designed to determine the effects of the combined addition of different levels of certain sugars (trehalose, sucrose and raffinose) and antioxidants (vitamin E, C and taurine), in Tris-egg yolk extender on frozen-thawed ram semen parameters. Semen samples were collected from five healthy, mature and fertile Iranian Afshari rams, twice a week for 8 weeks. Selected samples were pooled and diluted with a Tris-egg yolk extender containing different levels of sugars and antioxidants.
