The aim of research was to evaluate changes of physico-chemical characteristics, somatic cell count and curd quality during lactation and their relationship in Lacaune ewes. The study was carried out on eighteen ewes of the second lactation on an organic farm in Valašská Bystřice (Czech Republic). It was found that the stage of lactation significantly affected almost all monitored traits except...

In early lactation, susceptibility to disease is greatest, impacting cow health and productivity and leading to economic losses. Mastitis is the most economically costly disease to the dairy industry and is most frequent at this time. The objective of this paper is to discuss the energetic fuels used by leukocytes in the metabolic response during mastitis that may reveal potential mechanisms li...

Parturition in the sow is followed by a period of anovulation which is prolonged by lactation. Follicular development and luteinizing hormone (LH) secretion are depressed during the last month of pregnancy. After parturition, LH secretion increases but is again inhibited by the establishment of lactation. Lactating sows are submitted to stimuli originating from the young, whose intensity culmin...

Background: Breastfeeding is the safest and best method for nurturing infant growth and health. While the harmful effects of alcohol during pregnancy are well-established, the consequences of alcohol intake during lactation have been far less examined. The effects of alcohol intake with large amounts noted on the infant include drowsiness, diaphoresis, deep sleep, weakness, decrease in linear g...

1 Interpretative Summary: Effect of oral calcium supplementation on early lactation health 1 and milk yield in commercial dairy herds. By Oetzel and Miller, page 000. Low blood 2 calcium often occurs in older cows around calving and impairs subsequent health and milk yield. 3 Second lactation or greater cows in 2 commercial dairies with effective milk fever prevention 4 were divided into contro...

The modern dairy cow has been selected over generations for high milk production, with many successful dairy operations averaging over 13,500 kg of milk per lactation cycle per cow. This amount of nutrient output in the form of milk components puts a tremendous amount of pressure on the metabolism of the dairy cow, especially during early lactation. In fact, it is common to all mammals, includi...

Abstract Background Sheep milk is a nutritional and health-promoting food source for humans. The DEATH superfamily conserved protein family, some of its members are closely related to lactation. Systematic studies the important further understanding functions in mammary gland during lactation; however, there currently lacking. Results Herein, 74 were identified sheep, phylogenetic analyses indi...

A study was conducted at Deir Al-Hajar Research Station for Shami Camels, Administration of Livestock Research, General Commission Scientific Agricultural (GCSAR) during 2019 and 2020 to find the relation between vitamin c concentrations in milk, either stage lactation, parity (lactation number) or presence mastitis. For this purpose, thirty lactating camels from different parties were used.Mil...

the purposes of this study were to estimate the effects of risk factors on stillbirth parturition and evaluatethe effects of stillbirth on lactation performance in holstein dairy cows. data were obtained from a dairycattle herd located in isfahan province, iran. the logit of the probability of stillbirth was modeled usinglogistic regression and the effect of stillbirth on lactation performance ...

Abstract Background Sows are frequently subjected to various stresses during late gestation and lactation, which trigger inflammatory response metabolic disorders. Dietary fiber can influence animal health by modulating gut microbiota their by-products, with the effects depending upon source of dietary fiber. This study aimed evaluate impacts different sources on body condition, serum biochemic...
