The paper presents milk production results in a domestic Balkan goat breed reared in the north-western region of the Sharplanina massif. A characteristic of the domestic Balkan goat is that it is reared under poor conditions where other domestic animals can not find enough food to survive. These goats have a strong constitution, are robust and resistent to contagious and parasitic diseases, tolerant to hot, arid climate, and have modest nutritional requirements. The entire body (except the nose, hoofs, and lower portion of the tail) is covered by hair. Hair color varies. Most often it is reddish or gray, but can also be black, as well as chestnut, brown, patchy, and seldom, white. Body size increases with age, due to the fact that the domestic Balkan goat matures late, reaching full size at about 4 years of age. Mean values for height at withers and body length in mature goats were 66 and 70 cm, respectively. Lactation duration was 238 days, total milk production 178 kg per lactation, milk fat 3.68%. An average of 1.2 kids are obtained per goat annualy. Poor fertility of the domestic Balkan goat is caused by numerous reasons, mainly poor nutrition.

Marwari is a desert goat breed of India and is found in the western part of the country. It is well known for its tolerance of hot and cold climates, disease resistance and thriving in very harsh nutritional conditions. It is a hairy black coloured goat. The means of the body length, body weight and ear length were estimated as 54 cm, 83 cm and 20 cm in males and 49 cm, 72 cm and 16 cm in females. Males have larger and stronger horns than females. The average adult body weight in males and females is 46 and 30 kg, respectively. The overall milk yield at 200 days is 98 kg. The kidding percentage in field conditions is 79.3 percent and multiple birth is about 19 percent. The Marwari is an early maturing breed as the average age of puberty is 306 days. The mortality in kid is 3.3 percent and in adults 3.5 percent in field conditions. The marketing and production economics of goats in its home tract have been analysed to ascertain viability of goat enterprise. The breed improvement programme was started in 1990–91 in its home tract involving farmers' flocks.

The Asturcón Pony was on the verge of disappearing during the decade of the 1970. The creation of A. C. P. R. A (Breeders Association of Asturcón Ponies) and the measures undertaken by this association have made possible the present population of 400 of these animals and future perspectives for them to be bred at large for agrotourism and children's training in horseback riding and other equestrian sports. In spite of the fact that the recovery of the breed is being carried out with few individuals, our results show a high genetic variability. Analysing the allelic frequencies of blood polymorphism, we have obtained an average heterozygosity of 0.3649±0.1070 akin to that of other ponies such as the Dartmoor (0.3396±0.1060), Shetland (0.3158±0.1246 or the Connemara (0.3797±0.1000) and even superior to breeds such as the P. S. I. (0.2857±0.1194) and the Arabian (0.2299±0.0969).
