Milk goats autumn breeding technology

Milk goats exhibit a strong seasonal pattern in their estrus cycle, with most breeding occurring in the autumn months (September to October). Their lambs are typically born between February and March of the following year. High-performing dairy goats tend to have early estrus, higher ovulation rates, and better reproductive performance, while less productive sheep often experience delayed estrus, lower ovulation, and reduced fertility. Good-quality ram semen is characterized by high sperm concentration, good motility, and a large volume of ejaculate. During the first two months of the breeding season, it's important to improve the quality of forage feed. Rams and lean ewes should be given protein-rich green feeds, which are rich in vitamins and minerals. These nutrients help enhance male goats' performance, boost sperm vitality, and promote estrus in dairy goats, ultimately increasing ovulation rates. However, simply increasing the amount of concentrated feed isn't enough if you want to maintain high-quality breeding stock. As the saying goes, "Feed on your legs and feed on your mouth." That means balanced nutrition is key—overfeeding can lead to obesity, which reduces libido in rams and lowers pregnancy rates in ewes. In general, each ram during the breeding season should receive 10–15 kg of mixed feed daily, along with fresh grazing, 5–10 g of bone meal, 15–70 g of salt, and 2–3 eggs (crushed and mixed into the feed). Selecting high-performing males and females for breeding is crucial for improving both reproduction rates and productivity. In practice, it's essential to cull old, weak, or infertile animals and maintain a healthy proportion of ewes within the optimal breeding age to ensure the quality of the flock and increase profitability. Generally, lambs reach the ideal breeding age between 15 and 18 months, when their weight is around 30–40 kg. However, it's important to match them with the right breed to avoid raising them for an entire year unnecessarily. Proper breeding management is vital for the development of female goats. If young females with low weight or poor health are bred too early without proper feeding and care, it can negatively impact their growth and the quality of the next generation. The success of pregnancy is closely tied to the timing of breeding. Breeding during the peak of estrus significantly increases conception rates. Goats typically go into estrus every 20 days, with each cycle lasting 20 to 28 days. The mature egg remains viable for 4 to 8 hours after release, while ram sperm can survive in the female reproductive tract for about 24 hours. Therefore, the best time to breed is just before ovulation. For older ewes, whose estrus periods are shorter, timely breeding is crucial. Younger ewes may have longer estrus periods, so breeding can be slightly delayed. Middle-aged ewes fall in between. As the saying goes, "Old ones are quick, young ones are slow, and middle ones are just right." Additionally, multiple breedings during one estrus cycle can further improve conception rates.
