Boswellia Sacra

As an attempt to prevent transition-period-associated metabolic disorders and/or diseases, the potential benefits of Boswellia sacra (Bs) resin on hematology, immunity, metabolic status, udder and uterus health biomarkers, and milk production were examined in transitioning goats. From 2 weeks prepartum to 7 weeks postpartum, goats (n = 7/treatment) orally received 0 (control, nBS), 2 (BsL), or 4 (BsH) g of Bs resin/goat/day. The results showed that both Bs treatments significantly improved the activity of phagocytes. Both Bs treatments significantly decreased the concentrations of blood plasma urea, non-esterified fatty acids, hydroxybutyric acid, and interleukin-1β, whereas they increased the total antioxidant capacity compared with the nBS treatment. Both Bs treatments significantly decreased the uterine horn diameter and tended to decrease the intrauterine fluid content, indicating improved uterine involution compared with no treatment. Compared with the nBS treatment, both Bs treatments significantly decreased the milk somatic cell count. The lowest milk interleukin-1β content was observed in goats that received the BsL treatment, followed by those that received the BsH and nBS treatments. The BsL treatment significantly increased the concentration of immunoglobulin M (IgM) in the colostrum compared with the other treatments. Both Bs treatments significantly increased the daily milk yield compared with the nBS treatment but did not affect milk composition or the fat-to-protein ratio. In conclusion, supplementing lactating goats in the transition period with Bs resin at a dose of 2 g/goat/day positively affected the body lipid metabolism, udder and uterus health, colostrum IgM content, and milk yield due to its antioxidant and anti-inflammatory effects.

Crossbreeding in dairy cattle has been used to improve functional traits, milk composition, and efficiency of Holstein herds. The objective of the study was to compare indicators of the metabolic energy balance, nonesterified fatty acids (NEFA), beta-hydroxybutyrate (BHBA), glucose, body condition score (BCS) back fat thickness (BFT), as well as milk yield and milk composition of Holstein and Simmental cows, and their crosses from the prepartum period until the 100th day of lactation at the Livestock Center of the Ludwig Maximilians University (Munich, Germany). In total, 164 cows formed five genetic groups according to their theoretic proportion of Holstein and Simmental genes as follows: Holstein (100% Holstein; n = 9), R1-Hol (51–99% Holstein; n = 30), first generation (F1) crossbreds (50% Holstein, 50% Simmental; n = 17), R1-Sim (1–49% Holstein; n = 81) and Simmental (100% Simmental; n = 27). The study took place between April 2018 and August 2019. BCS, BFT blood parameters, such as BHBA, glucose, and NEFA were recorded weekly. A mixed model analysis with fixed effects breed, week (relative to calving), the interaction of breed and week, parity, calving year, calving season, milking season, and the repeated measure effect of cow was used. BCS increased with the Simmental proportion. All genetic groups lost BCS and BFT after calving. Simmental cows showed lower NEFA values. BHBA and glucose did not differ among genetic groups, but they differed depending on the week relative to calving. Simmental and R1-Sim cows showed a smaller effect than the other genetic groups regarding changes in body weight, BCS, or back fat thickness after a period of a negative energy balance after calving. There was no significant difference for milk yield among genetic groups, although Simmental cows showed a lower milk yield after the third week after calving. Generally, Simmental and R1-Simmental cows seemed to deal better with a negative energy balance after calving than purebred Holstein and the other crossbred lines. Based on a positive heterosis effect of 10.06% for energy corrected milk (ECM), the F1, however, was the most efficient crossbred line.

In a scientific economic experiment conducted in the experimental farm «Klenovo-Chegodaevo» (Moscow) on three groups of Holsteinized black-and-white cows with a milk yield of 7000 kg of milk per lactation, 10 heads in each, it was found that the inclusion in the diet of cows of the experimental groups tested protected fats (hydrogenated and fractionated) in the amount of 300 g per head per day, contributed to the tendency for more intensive metabolic processes in the rumen due to a slight increase in the concentration of volatile fatty acids by 5,6–7,4% and an increase in the mass of microorganisms in the contents of the rumen by 5,4–14,4% (P≥0,05). At the same time, an increase in the concentration of metabolic energy in the dry matter of the cows ration from 10,7 to 11,0 MJ / kg in the period from 21 to 120 days of lactation, due to the inclusion of protected fats in the diet of cows from the experimental groups, contributed to an increase in milk yield 4% fat content for 100 days of the experiment by 9,7% and 11,0% (P≤0,05), compared with the control, as well as the production of milk fat and protein, respectively by 9,6–11,0% (P≤0,05 in the second case) and 7,4–8,3%, feed costs expressed in ME decreased by 4,9–5,2%.

Lactose Synthesis

Dairy goats are often fed a high-concentrate (HC) diet to meet their lactation demands; however, long-term concentrate feeding is unhealthy and leads to milk yield and lactose content decreases. Therefore, we tested whether a buffering agent is able to increase the output of glucose in the liver and influence lactose synthesis. Eight lactating goats were randomly assigned to two groups: one group received a HC diet (Concentrate : Forage = 6:4, HG) and the other group received the same diet with a buffering agent added (0.2 % NaHCO3, 0.1 % MgO, BG) over a 19-week experimental period. The total volatile fatty acids and lipopolysaccharide (LPS) declined in the rumen, which led the rumen pH to become stabile in the BG goats. The milk yield and lactose content increased. The alanine aminotransferase, aspartate transaminase, alkaline phosphatase, pro-inflammatory cytokines, LPS and lactate contents in the plasma significantly decreased, whereas the prolactin and growth hormone levels increased. The hepatic vein glucose content increased. In addition, pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK) and glucose-6-phosphatase (G6PC) expression in the liver was significantly up-regulated. In the mammary glands, the levels of glucose transporter type 1, 8, 12 as well as of sodium-glucose cotransporter 1 increased. Cumulative buffering agent treatment increased the blood concentrations of glucose via gluconeogenesis and promoted its synthesis in the liver. This treatment may contribute to the increase of the milk yield and lactose synthesis of lactating goats.

A study was conducted on dairy cows aged 3-6 lactation, which were additionally fed with the Ketostop-El supplement at the rate of 300 g per head for 4 weeks after calving. The use of the feed supplement for 14 days led to a decrease in the number of monocytes, total protein, glucose, creatinine, total calcium and the activity of ALT and AST compared to their level before the use of Ketostop-El. Changes in the physical and chemical properties of urine and increase in the average daily milk yield were noted. The use of the supplement for 28 days contributed to a decrease in hematocrit, the sorption capacity of red blood cells, total protein, glucose, bilirubin, creatinine, total calcium, reserve alkalinity, ALT and AST activity and an increase in the number of basophils, eosinophils, and the concentration of inorganic phosphorus compared to the initial data. At the same time, a decrease in the level of protein and ketones in the urine was observed. An increase in the average daily milk yield and the mass fraction of fat in milk was also recorded. The feed supplement "Ketostop-El" has a positive effect on the body of dairy cows, as evidenced by the normalization of the clinical and metabolic status, as well as an increase in the dairy productivity of animals.

The Impact

Abstract The industries of Pomegranate juice processing generate enormous waste in peel’s form which are suggested and evaluated as a supplement in animal feed but pomegranate peel have high percent of tannins, So the aim of this paper is to assess the impact of mixing pomegranate peel (PP), detanninated pomegranate peel (DPP) and pomegranate peel with polyethylene glycol (PEG) on the digestibility of nutrients, the yield of goats milk and its composition, feed conversion and some parameters of blood. Moreover, simple economic assessment of the examined rations are considered. Sixteen lactating Zaraibi goats of about 3-4 years old (in their 2nd to 4th of lactation seasons with an average body weight of about 25 + 0.5 kg are used in the present study. After 14 days of parturition was randomly assigned into four groups, four animals per each tested ration (R) for 90days, R1: Control : 50% CFM + 25% Egyptian clover and 25% wheat straw, R2: Control ration+1% PP, R3: Control ration+1% PP + 20 g (PEG) and R4:Control ration+1% DPP. The results revealed that the PP contained 90.85% DM, 4.84% CP, 15.53% CF, 87.21%OM, 4.69% EE, 62.15% NFE and 15.28% tannins. No significant differences were found between the tested rations regarding nutrients digestibility except EE digestibility. Nutritive values of R2 and R3 were slightly higher than R4 and R1, respectively. Ration three (R3) was the best ration for daily milk yield and total milk yield, where R4 showed the worst one. Also, there are no significant differences for dry matter, SV and TDN intake. While, values of DCP intake were higher significantly (P<0.05), for R3 and R2 followed by R4 then R1. Regarding feed conversion, R4 was superior to other tested rations followed by R1 then R3 followed by R2. All blood serum parameters were in the normal rang which support that the healthy effect of tested additives in goats rations. It seems that R2 and R3 could be used successfully for lactating goats, but R3 is very expensive from economical point of view, where R3 was negatively economical effect, and not recommended.

SummaryFive lactating goats which had kidded normally in March were mated during seasonal anoestrus in May, at the time of peak milk production, after ovulation had been induced using gonadotrophin-releasing hormone (Knight et al. 1988). Milk yield was unaffected by the hormone treatment, and decreased at the same rate as that of control (non-pregnant) goats for the first 8 weeks of the pregnancy. Thereafter yield declined more quickly in the test goats and just before parturition (in October) was 57% of the control value. Following parturition in the test animals, yield rose rapidly as the second lactation was established. None became ‘dry’ at any stage. Yield continued to decline with advancing lactation in the controls, which were mated normally in October or November and dried-off in December. During their second (‘extra’) lactation in the winter the test animals produced 12% less than in a normal second lactation in summertime; during the year the extra lactation meant that the test animals produced 73% more milk than the controls. In some, a second concurrent pregnancy was established during the extra lactation, with the resuit that three lactations were obtained in the time normally taken for two. Mammary cell number and proliferation rate were both higher in the pregnant animals than in the controls in week 23 of the first lactation.

The objective of this experiment was to investigate the effects of forage species and feeding systems on ruminal fermentation, microbiota (Butyrivibrio fibrisolvens, Fibrobacter succinogenes and total bacteria) and conjugated linoleic acid (CLA) concentration of milk in dairy goats. Twenty female crossbred Saanen lactating goats (~35 ± 3.0 kg bodyweight) in early to mid-lactation stage were assigned to a 45-day completely randomised-design feeding experiment, with the following four forage (roughage) treatments: cut-and-carry grass (CG), grazing of grass (GG), cut-and-carry leucaena (CL) and grazing of leucaena (GL; n = 5). All animals were given concentrate equivalent to 1.5% of their bodyweight. The grass used in the study was napier Pak Chong 1 grass (Pennisetum purpureum × Pennisetum americanum hybrid). The results showed that irrespective of the type of forage, grazing goats (GG and GL) had a higher (P B. fibrisolvens, F. succinogenes and total bacteria were significantly (P P B. fibrisolvens (involved in the synthesis of milk CLA), resulting in a higher milk yield, and enhances c9, t11 and t10, c12 CLA in goat milk.
