概括

随意养系统允许母猪满足其营养需求,改善小猪生长和料效率,而不会对母猪的体重或受孕产生负面影响. 这些系统还可以通过增加食行为来提高母猪福利.

科学领域:

动物科学动物科学
动物养殖动物养殖
动物福利动物福利

背景情况:

在哺乳期,种子的营养需求会动态变化.
养方案必须适应播种行为和生产特征,以获得最佳结果.
目前的养系统可能无法完全满足母猪的生理和行为需求.

研究的目的:

评估四种不同的养系统在哺乳期对母猪和小猪生产率的影响.
评估养系统对母猪和小猪健康和福利指标的影响.
为了比较非随意养与计算机监控和机械随意养系统.

主要方法:

61只母猪及其幼被分配到四个养系统:控制系统 (CON,非自由食) 和三个自由食系统 (计算机监控的COMP,COMP+和机械MECH).
收集的数据包括每天的料消失,小猪生长,母猪体重,受孕率,健康评分和母猪行为分析 (96小时/母猪).
行为分析侧重于两个关键的哺乳阶段 (2-4日和23日) 的养时间和刻板印象.

主要成果:

与CON相比,Ad libitum系统 (COMP,COMP+,MECH) 导致总体料消失率较低,但每种消耗的料的小猪生长率较高.
猪胎死亡率,母猪体重减轻率和随后的受孕率在治疗过程中没有显著差异.
在COMP和COMP+系统中的小猪表现出较少的头部病变,所有自由选择组中的母猪在槽中花费了更多的时间,这表明养时间增加了.

结论:

随意养系统使母猪能够消耗适当量的料,有效地将其转化为小猪生长,而不会影响母猪的身体状况.
在ad libitum系统中增加食时间可能会满足母猪食的行为需求,可能会改善福利.
这些发现支持开发先进的哺乳养系统,以提高动物福利和生产力,同时优化料成本.

Parental Care

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

The Mammary Glands

The Mammary Glands

The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

Development of Human Microbiota

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...
