Management practices in a piggery include the following except

Management practices in a piggery include various activities that help to promote the health and well-being of the pigs and maximize their productivity. These practices typically include disinfecting pens, regular cleaning of feed and water troughs, and isolating sick animals to prevent the spread of disease. However, weekly vaccination of pigs is not a common management practice in many piggeries. While vaccination can be an effective way to prevent the spread of certain diseases, it may not be necessary to do so every week, depending on the specific diseases prevalent in the area and the health status of the herd. Other management practices that are commonly employed in a piggery include regular feeding and monitoring of the pigs, proper waste disposal, and regular veterinary checkups.
