“…It has been shown in Sahiwal dairy cows that oxytocin has considerable effects on some milk minerals like Na, Cl and Cu, respectively, were higher (19.74, 9.39 and 146.89%), while K and lactose decreased by 10.06 and 0.39%, respectively (Hameed et al 2016), while, Akhtar et al (2012) showed that milk production improved by oxytocin injection in Buffalo.…”

Ocitocina: funções e ativação RESUMO O objetivo desta revisão é descobrir a atividade da ocitocina em vários sistemas biológicos do corpo relacionados às funções reprodutivas. A ocitocina é um hormônio peptídico produzido no cérebro, armazenamento e secreção da hipófise na maioria dos animais, especialmente nos mamíferos. A ocitocina foi descoberta pela primeira vez por Henry Dale em 1906. Considerando que sua estrutura foi descoberta em 1952. A ocitocina possui uma ampla variedade de funções fisiológicas, como remoção de leite, comportamento materno, câncer e comportamento sexual nos dois tipos de sexo (masculino e feminino) , por exemplo, desempenha um papel no desempenho da excitação peniana, ejaculação, glândulas acessórias e nas contrações dos músculos lisos do útero e pélvica durante o acasalamento e parto, crescimento e desenvolvimento do nível do corpo lúteo e progesterona no sangue. Além disso, o efeito da ocitocina em alguns hormônios como a prolactina e o hormônio luteinizante. Além disso, existe uma relação entre ocitocina e tolerância ao estresse. Portanto, é importante e necessário entender os efeitos da ocitocina nas funções de alguém para fornecer informações sobre os processos biológicos do corpo que controlam esse hormônio. PALAVRAS-CHAVE: hormônio, remoção de leite, reprodução animal, tolerância ao estresse ABSTRACT The objective of this review is to uncover the activity of oxytocin in various biological systems in the body related to reproductive functions. Oxytocin is a peptide hormone produced in the brain, storage, and secretion from the pituitary gland in most animals especially the mammals. Oxytocin was discovered at first time by Henry Dale in 1906. Whereas, its structure was discovered in 1952. Oxytocin has a wide variety of physiological functions such as milk removal, maternal behavior, cancer and sexual behavior in both type sex (male and female), for example, its play a role in excitation penile, ejaculation, accessory glands performance and the contractions of smooth muscles of the uterus and pelvic during mating and parturition, growth and development of the corpus luteum and progesterone level in blood. Also, oxytocin effect on some hormones such as prolactin and luteinizing hormone. Furthermore, there is a relationship between oxytocin and stress tolerance. So, understanding the effects of oxytocin on somebody's functions is important and necessary to provide information about body biological processes which control by this hormone.

“…Milk fat is the most complex of all the natural fats as it contains many different fatty acids. The fatty acids profile of milk is associated with many factors such as animal origin (breed and selection), stage of lactation, mastitis, ruminal fermentation, feed-related factors, seasonal and regional effects [5][6][7][8]. Almost 98% of the fats in bovine milk are made up of triacylglycerides [9] and the remaining approximate 2% is made up of diacylglycerides, cholesterol, phospholipids, and free fatty acids [10].…”

Fat is a most important constituents in milk and enhance the nutritional value of milk. The fatty acids profile of milk is associated with many factors such as animal origin, lactation stage, ruminal fermentation, feed-related factors, seasonal and regional effects.The fatty acids composition in Himacahli Pahari cow, Jersey cross-bred cattle, Gaddi goat and local non-Gaddi goat milk was analyzed by gas chromatography-mass spectrometry (GC-MS). Maximum levels of saturated fatty acids (SFAs) were present in local non-Gaddi goat (78.80%) followed by Himacahli Pahari cattle (72.58%), and Jersey cross-bred cattle (59.12%) milk. Extremely low levels of polyunsaturated fatty acids (PUFAs) were present in Himacahli Pahari cattle, Jersey cross-bred, and local non-Gaddi goat milk. In Himacahli Pahari cattle milk, saturated palmitic acid (22.57%), stearic acid (15.92%) and monounsaturated oleic acid (26.17%) were present. In Jersey cross-bred cattle, higher amount of saturated myristic acid (18.42%), stearic acid (29.04%) and monounsaturated oleic acid (31.26%) were detected. The fat present in goat milk was found to be a rich source of medium chain fatty acids. The occurrence of palmitic acid in higher amount might be responsible for intense flavour in local non-Gaddi and Gaddi goat milk but needs further research. Among all the breeds the saturated fatty acid (SFA's) content was higher whereas the polyunsaturated fatty acid (PUFA's) present in lower amount.
