Relationship between pre-pubertal nutrition plane with reproduction performance and milk quality in Kurdish female kids

“…Reproduction is very energetically demanding, energy balance is arguably the next most powerful regulator of reproductive function. Variation in the level of nutrition (and changes in energy balance) can affect the reproductive cycle at almost any stage [2][3][4].…”

“…Various studies have shown that in small ruminant (sheep and goats) variations in energy balance, defined as the difference between the pool of disposable energy and the pool of expended energy, can influence any of the three levels of the reproductive axis (hypothalamus, pituitary gland, gonads) and also impact on regulatory feedback mechanisms [1,4,20]. And also, Jaborek et al [18] recommend that availability of energy has a key role on reproductive efficiency, because of the reproductive axis sensitivity to the adequacy of stores and nutrition of metabolic reserves.…”

“…Due to the live weight importance, the factors like before and after weaning weight gain crucial factors in determination of age at puberty [3]. Utilization of diet with high energy and protein increased plasma concentrations of leptin in ewe lambs [3,4]. If in the first autumn, a kid could not achieve puberty, until the next breeding season, it will be delayed [5,6].…”

“…This shrub was introduced in Tunisia for over a century, particularly in the semiarid and arid zones [23]. First, to serve the rangeland rehabilitation, due to the presence of 100-140 g crude protein/kg DM with a high levels of tannins CT (40-80 g Eq leucocyan/kg dry matter) [24]. Then it is used in antibacterial [25], and anti inflammatory [26] activities.…”
