“…The current results reported that all experimental rations were isonitrogenous and isocaloric during time of lactation. The calculated chemical composition is in agreement with the chemical composition of experimental rations obtained by Ben Salem et al (2005) with dairy goats, in early lactating cows (Gowda et al, 2013), in primiparous buffalo (Abdel-Latif et al, 2016), and in sheep (Santos et al, 2017) which supplied with propylene glycol.…”

“…The PG could be increased the energy in the late phase of pregnancy and reduction levels of metabolites used for interpretation of energy balance such as beta-hydroxybutyric acid (BHBA) and non-esterified fatty acid (NEFA) concentrations (Mecitoğlu et al, 2017). It also optimized the metabolic parameters in pre and post-partum periods of sheep which have no negative effects on the suckling lambs (Santos et al, 2017). On the other hand, Akamatsu et al (2018) suggests that PG prevents liver dysfunction related to an insufficiency of bile excretion occurs in cows with ketosis.…”

To evaluate the effects of propylene glycol (PG as powder) on some nutrition parameters (digestion coefficient and nutritive values) and some productive parameters (milk yield and composition) and its effects on the quality of milk processing for Domiatti cheese). An experiment was conducted by eighteen lactating Zaraibi goats in 3 rd lactation season with an average body weight of 36±5.46 Kg and aged 39 months. In this experiment, three treatments were employed as six does in each treatment. The treatments done up to 21 weeks during lactation season and included: (1) control without PG (PG0), (2) 10g PG /doe/day (PG1) and ( 3) 20 g PG/doe/day. All treated goats were received basal ration contained 50% concentrate feed mixture (CFM) + 50% roughage (as berseem hay and rice straws) through lactation period up to 21 weeks. Apparent digestibility of CP, TDN and DCP was affected (P<0.05) by PG administration. Acetate and propionate were increased by using PG, but level of butyrate has increase significant for PG0. Moreover, the results could be showed that milk yield and milk compositions were affected (P<0.05) by the PG addition compared to control. Also, increasing PG levels from 10 to 20 g /does/day did not have any significant effect on milk yield, milk composition and other nutrition parameters. The cheese sample yield was slightly decreased particularly within PG1 and PG2 compared to PG0 cheese. The total solids and titratable acidity were slightly increased and pH values were slightly decreased by using PG milk. The PG cheese samples had significant (P<0.05) differences in TN/DM%, FA/DM% during the ripening period. The cheese made from PG1 and PG2 had the higher (P<0.05) score points for organoleptic properties than PG0 after continually storage period for 60 days. The results indicate that PG is an appropriate alternative for goats to prevent energy deficiency in the lactation period, while increasing the daily PG dose from 10 to 20 g has no significant but observed beneficial effect.

“…Therefore, the lower values for total proteins and globulins verified at 30 days probably represent the transition period in the immunoglobulin content in the bloodstream, which is characterized by the end of the degradation process of immunoglobulins passively received via colostrum and by the initial phase of active production of immunoglobulins by the animal itself (Mohri et al, 2007;Silva et al, 2010). In subsequent months, the increase in values results mainly from the increase in gamma globulin concentrations resulting from the antigenic stimulation of lambs (exposure to antigens in the extrauterine environment and by vaccination) and from the maturation of the immune system (Silva et al, 2010;Delfino et al, 2014;Santos et al, 2017).…”

“…According to Silva et al (2010) and Chai et al (2015), lambs older than 30 days already present rumination and become proficient in the use of nitrogenous compounds from the diet, which causes a gradual increase in albumin concentrations until 90 days, as observed in this study. The decrease observed at 120 days, as a delayed response from albumin, in turn, might have been caused mainly by weaning, since depriving the lambs of milk reduces the total dietary protein and energy intake (as observed at 76-90 days; Table 3) and, consequently, the use of available forage protein and albumin synthesis (Fernandes et al, 2012;Santos et al, 2017). It is noteworthy that the dynamics of albumin is not only changed by nutrition, but also by the ability of the liver to synthesize it, which, during the neonatal period, is still influenced by the development and maturation of hepatic metabolic processes (Mohri et al, 2007;Souza et al, 2014).…”

Ruminants Full-length research article Dynamics of biochemical parameters in lambs during the first four months of life ABSTRACT-We aimed to verify whether age influences the biochemical profile of healthy lambs during the first four months of life by characterizing the dynamics of its parameters and verifying whether there are differences between the profiles of growing animals and the reference values established for adults. Blood samples of 34 ½ White Dorper × ½ Suffolk female lambs were collected at 30, 60, 90, and 120 days of age, and the serum concentrations of total proteins, total globulins, albumin, urea, creatinine, bilirubins (total, conjugated, and unconjugated), total cholesterol, triglycerides, glucose, gamma-glutamyltransferase, aspartate aminotransferase, and creatine kinase were determined. Descriptive statistics of these parameters were performed to compare them with the reference intervals used for adult sheep. Age influenced the dynamics of all the biochemical parameters between 30 and 120 days of age. Moreover, except for the total, conjugated and unconjugated bilirubins, total cholesterol, and aspartate aminotransferase means, the values of the lambs differed from the reference intervals established for adults. In conclusion, there is an influence of age on biochemical parameters in healthy female lambs in the first four months of life, and often the biochemical parameters of young animals differ from those of adults. Therefore, the interpretation of tests performed on growing animals should be made based on specific reference intervals for this age group.

“…Varying feed composition, mainly by considering different batches of silage supplied during the experiment, could result in a small increase in uric acid levels in the second, third, and fourth weeks. The results also show that treatment with green propolis does not result in any hepatotoxic effects that can be observed through varying levels of total proteins (43).…”

Brazilian Green Propolis as a Therapeutic Agent for the Post-surgical Treatment of Caseous Lymphadenitis in Sheep

et al. 2019

As antibiotics are ineffective when used to treat caseous lymphadenitis, the surgical excision of lesions is often required. Iodine solution (10%) is currently the choice for the post-surgical treatment; however, it may cause histotoxicity. Propolis are resinous substances composed by a mixture of different plants parts and molecules secreted by bees. As green propolis has already proven to possess anti-bacterial and wound healing properties, this study aimed to evaluate the use of a green propolis-based ointment as a therapeutic agent for the post-surgical treatment of caseous lymphadenitis. The caseous lesions of 28 sheep were surgically excised before dividing animals into two groups: (1) iodine-treated animals and (2) sheep treated with an ointment made with a previously characterized green propolis extract. Clinical data of animals, size of the scar area, the presence of moisture and secretion in the surgical wound, the humoral immune response against the bacterium and the susceptibility of C. pseudotuberculosis clinical isolates to the green propolis extract were analyzed. The green propolis-treated group presented complete healing of the surgical wound 1 week before the iodine-treated group. Additionally, animals treated with the green propolis ointment had fewer cases of wound secretion, but it was not statistically different from the iodine-treated group. No clinical signs indicating green propolis toxicity or other side effects were found, associated with a faster and more organized hair recovery by propolis use. The green propolis extract was able to inhibit the growth of 23 from the 27 C. pseudotuberculosis clinical isolates, with minimum inhibitory and minimum bactericide concentrations ranging from 01 to 08 mg/mL, and did not interfere with the humoral immune response against the bacterium. In addition, green propolis was able to inhibit biofilm formation by four of the C. pseudotuberculosis clinical isolates. We concluded that green propolis is a promising therapeutic agent to be used in the post-surgical treatment of caseous lymphadenitis in small ruminants due to its effects on surgical wound healing, hair recovery, inhibition of wound contamination and bacterial growth.
