BOAR FEEDING AND REPRODUCTIVE HEALTH.

In pig farming the major aim is to produce large litter sizes that are healthy with high reproductive capacity.The success in pig farming is hinged on genetics as the pig cannot exceed the genetic capacity hence a good genetic line is chosen. Housing and management also influences the outcome of venture, proper housing and animal management is another crucial point. The major key to success is feeding programme,the animals must have access to good quality feed ,balanced and readily available. The importance of feed in the boar cannot be overemphasized as the quality of sperm produced will set the genetic track for the farm. When preparing the feed,you need to ensure that all ingredients that will ensure the following are available; proper muscle development, proper bone development and production of high quality and quantity of sperm. The feed should provide the necessary daily feed intake which must contain dietary energy and protein, additives and vitamins such as organic selenium, vitamin E, zinc, biotin, vitamin C. The breeding boars must be mature animals, so also must the to sows. An underweight or overweight boar or sow will often result in breeding failure,hence feeding should be monitored. Boar libido unlike sperm production, cannot be easily manipulated by changing dietary protein and energy levels but its a known fact only prolonged conditions of over-feeding or under-feeding, and excessive extreme cases of body condition change, can negatively impair boar libido. Scientific research proves that protein and amino acids lysine and methionine + cystine, play an important role in sperm production. In particular, the sulphur-containing amino acids methionine/cystine affect the secretory activity of the epididymis, thus significantly enhancing sperm volume. This effect is very marked in intensively used boars, where sperm production has been shown to be positively influenced when extra protein and methionine was added to the diet. Protein combined with adequate energy intake is very crucial for optimal sperm production.

VITAMIN E AND HORSE METABOLISM.

Vitamin E it benefits all horses, but will green grass and sunshine be enough? Would a high level performance horse benefit from additional vitamin E? What does vitamin E do in the horse? Vitamin E is a term used to describe a group of compounds known as tocopherols and tocotrienols. In equine nutrition most attention is paid to alpha-tocopherol. Alpha-tocopherol plays an important role in something called the glutathione pathway, which protects cells from oxidative damage, as well as reacting with free radicals produced by processes such as the lipid peroxidation chain reaction. Free radicals cause damage in cells because they have an odd number of electrons, which gives them an unstable electrical charge. In an attempt to become stable they “steal” electrons from other molecules. This causes a new molecule to be unstable, and it might not be able to perform its function within the body. A chain of oxidative destruction can result within the cell, which can negatively impact cell function and potentially cause cell death. Free radical formation is a natural consequence of various molecular processes within the cell, and we often hear it referred to as “oxidative stress.” It’s easy to label free radicals as “bad,” but they are in fact a perfectly natural consequence of the body using fats and carbohydrates for energy.Read more here;http://www.thehorse.com/articles/36737/when-do-horses-need-vitamin-e?utm_source=Newsletter&utm_medium=nutrition&utm_campaign=11-16-2015
