The aim of this study was to assess the performance and meat quality of meat-type guinea fowl fed commercial diets under two different feeding programs similar to those for turkeys and broilers. Findings of the study suggest that these diets can be used in meat-type guinea fowl rearing without affecting the productive traits and meat quality. However, due to the lower price of chicken feed (due to lower protein content), its use seems to be more justified from an economic point of view.

Insulin-like growth factor 1 (IGF1) is one of the important endocrine hormones that plays a role in regulating growth and development of animals. In this study, we found two single nucleotide polymorphisms (SNPs) in the exon3 region of IGF1 in the Shitou goose. IGF1 mRNA was extensively expressed in various tissues, with high abundant expression in the liver, breast muscle and leg muscle at three growth stages. This provides a foundation for regulatory mechanisms of IGF1 in geese.

In this study, the meat quality traits and fatty acid composition of Hair Goat and Saanen × Hair Goat (G₁) crossbred kids fattened under intensive, semi-intensive and extensive conditions were determined. The conjugate linoleic acid contents of Hair Goat kids were respectively measured as 0.48 %, 0.55 % and 0.65 %. The conjugate linoleic acid contents of Saanen × Hair Goat (G₁) kids were respectively measured as 0.52 %, 0.58 % and 0.73 %.

As part of the development of a breeding programme for dairy goats to support sustainable production, we aimed to identify selection traits measured in regular milk recording. In summary, the length of the animal's productive life, lifetime efficiency, and the milk yield efficiency with respect the total number of lactating days are suitable traits to indicate lifetime productivity in dairy goats. Breeding associations must now decide which traits to implement in the breeding programme.

Tibetan pigs are well adapted to high-altitude environments with a set of physiological features for more efficient blood flow for oxygen delivery under hypobaric hypoxia. We established the anatomy, physiology and molecular characteristics of the lung adaptive intelligence. Our finding suggest that the lung genetic mechanism of hypoxic adaptation in Tibetan pigs is valuable to understand.
