Effect of adding sunflower oil in the ration on some productive traits in Awassi ewes

This study was designed to investigate the effects of the addition of different ratios of sunflower oil to the diet of Awasi ewes on the rumen fermentation and milk composition. It was conducted by using 12 Awassi ewes (2-3.5 years old) with average body weight 56.62 kg. The ewes were randomly divided into three groups. Each group had four ewes according to the age, body weight and milk yield. The ewe in each group received 1.4 kg/ dry matter for three rations consisting of barley, wheat bran, soybean meal and alfalfa hay. The first group was fed on control ration, while 2.5 and 5 % of sunflower oil were included in the rations of the second and third groups, respectively. The results showed that the treatments had no significant effect on the average body weight, milk production and milk composition (lactose, protein and SNF percentage). Milk Fat percentage was significantly (P<0.05) decreased in second and third groups (4.30 ±0.31 and 4.23 ±0.40) %, respectively as compared with the control group (5.89 ±0.53 %). The pH value of rumen liquor in hours (0 and 3) after feeding showed no significant differences between groups, also there were no significant differences in the volatile fatty acid and ammonia concentration in the rumen liquor in all groups, despite that the volatile fatty acid decreased insignificantly in all treated groups as compared with the control group after feeding. The blood parameters were not affected by the experimental treatments. These results indicated that the fermentation patterns were affected by the increased oil supplementation to the diet of ewes.

Introduction: Recently, new commercial infant formulas have been composed considering novel fat blends and oligosaccharides to better resemble the fatty acid (FA) composition and stereospecific distribution (e.g., increased amount of ß-palmitate) as well as probiotics content of human breast milk. We hypothesized that these newly composed infant formulas may decrease fecal FA soap excretion and may positively affect erythrocyte FA profiles compared with regular formulas. Methods: Healthy infants were randomly assigned to receive a high-sn-2-palmitate formula (>25% of the PA is esterified to the sn-2 position of the glycerol backbone, verum: n = 30) or a “standard” formula containing <10% of PA in sn-2 position and no oligosaccharides (control: n = 27); a non-randomized group of breast-fed infants served as control. Anthropometric data of the infants (body weight, recumbent length, and head circumference) were recorded at inclusion (visit 1) and 6 and 12 weeks after onset of intervention (visits 2 and 3). Blood samples for erythrocyte FA analysis (gas chromatography) were taken at visits 1 and 2; stool samples were collected at visit 2. Results: Quantitative formula intake (mL/kg body weight × day) at visit 2 (verum: 155 ± 30, control: 164 ± 30) and visit 3 (verum: 134 ± 26, control: 134 ± 21) was comparable. Six weeks after onset of intervention, stool total FA soaps, palmitate soaps, and total FAs were similar in both formula-fed groups but significantly higher than in breast-fed infants. During the 6-week intervention, erythrocyte palmitate decreased significantly from baseline in all 3 groups with no group differences (verum: 29.20 ± 1.17 to 27.12 ± 0.66, control: 29.88 ± 2.00 to 27.01 ± 0.94, breast-fed: 30.20 ± 0.86 to 26.84 ± 0.98). For selected FAs, significant changes over time in verum and control group were obvious but without formula effects. Some variations in the FA profile of breast-fed infants compared to both verum and control groups were observed. Conclusions: In contrast to our hypothesis, feeding a newly composed infant formula based on a fat blend with 25% of PA in the sn-2 position of triacylglycerols and supplemented with a prebiotic could not decrease insoluble FA soap excretion compared with a standard product; in this respect, breastfeeding is obviously the best choice. Surprisingly, erythrocyte FA profiles were comparable in formula-fed and breast-fed infants; obvious alterations in FA composition of the respective fat sources and structure did not affect FA incorporation into membranes. Caution should be, however, exercised in drawing robust conclusions in the absence of larger, adequately powered intervention studies.

The current experiment was designed to investigate the effect of zeranol implantation on lambs and goats’ kids raised under commercial conditions. Ten male Awassi lambs (AL) (4-5 months old) with an average body weight of 33.7 ± 0.5 kg and 10 male black goat kids (GK) (3-4 months old) with an average body weight of 18.8 ± 0.7 kg were used in the experiment. The experiment was conducted in Berebuhar village close to Duhok city in May the 15th, 2019The animals from each group were randomly divided into two subgroups, the first group was the control group and the other group was implanted with 24 mg zeranol. The animals were grown for 43 days and then slaughtered. Growth rate, average daily gain and carcass characteristics were measured. Data were analysed as factorial 2 × 2. The results showed that implantation both animal groups with zeranol significantly reduced testicular weight by approximately 55 % and 71 % for goat kids and Awassi lambs respectively. Moreover, the results showed that zeranol implantation found to reduce total body fat from 892 to 816g in goat kids and from 3395 to 2856 g in Awassi lambs. It can be concluded that zeranol implantation has an effect on total body fat and fat tissue distribution.

The purpose of this study was to evaluate present level of productivity and determine linear body traits of Alpine goats raised in Serbia on smallholder farms. Data were collected from 22 smallholder farms located in Belgrade district, with total of 330 purebred Alpine does 2-9 years of age, 145 yearling does and 476 kids. Traits measured were: body weight of does, body weight of kids at birth, 30 days of age and at weaning (90-120 days), prolificacy of mature and yearling (primiparous) does, six linear body traits of does (wither height, body length, hearth girth, chest depth, chest width, pelvic width) and milk production (milk yield, milk fat and milk protein content). The analysis showed the average body weight of does to be 54.96 kg, while the average body weight of kids at birth, 30 days of age and weaning was 2.73 kg, 8.7 kg and 18.3 kg., respectively. Prolificacy was 144% in mature and 125% in yearling does. Measurements of linear body traits were: wither height 67.87 cm, body length 71.92 cm, hearth girth 81.79 cm, chest depth 32.93, chest width 21.49 cm and pelvic width 17.63 cm. Among dairy production traits, following results were obtained: lactation length 220.73 days, total milk yield 531.66 kg, milk fat content 3.33% and milk protein content 3.16%. It was concluded that the overall productivity of Alpine goats raised under smallholder production systems in Serbia is satisfying. Giving the fact that these animals are usually kept under poor conditions, many of these productive traits are very good.

Purpose. Evaluate the effect of metabolic control of gestational diabetes mellitus (GDM) on the perinatal period course and anthropometric parameters of newborns.Materials and methods. 300 newborns were divided into 4 groups depending on the metabolic control of the mother. Group 1: fasting glycemia <5.1 mmol/L, 1 hour after meals <7.0 mmol/L (n = 50); Group 2: <5.3 mmol/L and <7.8 mmol/L (n = 90); Group 3: > 5.3 mmol/L and> 7.8 mmol/L (n = 46), respectively; Group 4: control (n = 114). The analysis of the perinatal period course was carried out, the anthropometric parameters were estimated according to the tables INTERGROWTH-21st.Results. Differences in the frequency of obstetric injuries, which risk is associated with «above average» body weight of the newborn (p = 0.04), were found between the GDM group and the control group (38.7 and 12.3%, respectively, p = 0.0000005). The risk of having a baby with «above average» body weight (Group 1/Group 4, OR = 1.9, p = 0.1; Gr. 2/Gr. 4, OR = 2.6, and Gr. 3/Gr. 4, OR = 3.7, p <0.05), the ratio of weight/length (Gr. 1/Gr. 4, OR = 0.9, p = 0.9; Gr. 2/Gr. 4, OR = 3.6, and Gr. 3/Gr. 4, OR = 4.9, p <0.05) and head circumference (G.1/Gr. 4, OR = 1.1, p = 0.6; Gr. 2/Gr. 4, OR = 2.5, and Gr. 3/Gr. 4, OR = 2.9, p <0.05) was higher in Groups 2 and 3 than in Group 4. In the early neonatal period with GDM, hypoglycemia was more common than in the control Group 4. The lowest risk was in Group 1 (Gr. 1/Gr. 4, OR = 4.8; Gr. 2/Gr. 4, OR = 6.7; Gr. 3/Gr. 4, OR = 7.9, р < 0,05).Conclusions. Group 1 showed the lowest frequency and risk of adverse effects, which meets the control criteria of the Russian consensus.

Effect Of Feeding

Twenty–one multiparous Holsteins were used in a cross over design with two 28-d periods. Cows were randomly assigned to two treatments to assess the effect of textured and pelleted concentrates fed with alfalfa cubes on feed intake, milk yield, milk composition and rumen volatile fatty acid concentrations. Those animals receiving the textured concentrate had significantly (P < 0.05) higher milk yield and milk fat percentage than did those animals fed the pelleted concentrate. A significant difference in the ratio of milk protein to milk fat was also observed with the cows receiving the pelleted concentrate having a ratio of 1.31 and the cows receiving the textured concentrate a ratio of 1.02. No significant (P < 0.05) differences were observed between the textured and pelleted feeds in total or individual volatile fatty acid concentrations. These results indicate that the feeding of textured concentrates can lead to an increase in milk fat production when compared with the feeding of pelleted concentrates.

The aim of the present study was to assess the effects of a prolonged photoperiod on growth rate and sexual maturation in brook trout Salvelinus fontinalis. The task of the experiment was to determine the most effective light regimen capable to minimizing the effects of puberty, including impairment of somatic growth and further general characteristics. In this regard, the studied fish were reared under three photoperiod regimens in which fish were exposed to 24 h continuous light alternating with 24 or 48 h under the ambient photoperiod or 48 h continuous light alternating with a 24 h ambient photoperiod. A control group was reared under the natural ambient photoperiod. Four-hundred and fifty fish with an average initial body weight of 101.3 ± 1.2 g were used for each experimental group (three replicates of each treatment plus control). A statistically lower growth rate showed control groups in both sexes. At the end of the study, control males had an average body weight of 226.6 ± 39.8 g and control females a body weight of 199.8 ± 12.2 g. At the same period, a significantly higher average body weight was found in groups reared 24 h under ambient photoperiod alternating with a 48 h continuous light regime (2CP:1AP) in both sexes (296.56 ± 62.5 g—males, and 239.9 ± 19.2 g—females, respectively). A significantly higher percentage of sexually mature fish was observed in the control group (80% of males and 29% of females, respectively). We found significantly fewer sexually mature females compared to males. The lowest survival was observed in group 2CP:1AP at 92%. It was concluded that regimen under which fish was exposed to 48 h of natural ambient photoperiod alternating with 24 h of constant light (1CP:2AP) lead to the successful delay of gonad development and onset of puberty and increased somatic growth in both sexes.

In this work there was investigated the influence of selenium and deodinases blockers on juvenile rats body weight during three months. The experiment was carried out on 64 rats divided into eight groups with eight individual animals per group. Following groups were formed: 1. Se+PTU-IA- (control group), 2. Se+PTU+IA+, 3. Se+PTU+IA-, 4. Se+PTU- IA+, 5. Se-PTU-IA-, 6. Se-PTU+IA+, 7. Se-PTU+IA- and 8. Se-PTU-IA+. The groups labeled (Se+) were selenium adequate and they were fed with food that contained 0.334 mg Se/kg. The groups labeled (Se-) were selenium deficient and obtained food with 0.031 mg Se/kg. As deiodinases blockers there were used propylthiouracil (PTU+) in a dose of 150 mg/L of drinking water and iopanoic acid (IA+) in a dose of 6 mg/100 g TM intraperitoneally. Body weight of experimental rats was measured every seven days. After three weeks of treatment there were taken blood samples of animals from all experimental groups and following parameters were determined: selenium concentration in blood, thyroxine (T4), triiodothyronine (T3) and thyroidstimulating hormone (TSH) in blood plasma. Analysis of the samples showed that the animals from the groups treated with PTU had lower body weight in regard to the control group, as well as lower concentration of T3 and T4 in plasma. Selenium deficient rats had lower average body weight compared to the selenium adequate ones after three weeks, but there were no differences in thyroid hormones concentration. The lowest average body weight was noticed in selenium deficient rats groups treated with PTU.

Abstract. The aim of the presented study was an estimation of the zinc bioavailability derived from amino acid complexes with methionine, lysine and glycine in growing lambs. 48 lambs, Polish Merino × Romanowski × Charolaise crossbreed, at age about 10 weeks and average body weight of 20 kg were randomly divided into 4 experimental groups. Animals were kept collectively and fed with concentrate and hay in amount: 0.7–1.2 and 0.3–0.5 kg/day/head, respectively. After rearing period 6 rams from each group with average body weight of about 30 kg were divided into digestibility-balance experiments. At the end of the experiment the blood samples were taken, then from each group 8 lambs were chosen, killed and during dissection tissue samples were taken (liver, pancreas, kidney and rib bone). In tissue samples as well as in fodders and excrements the content of zinc was determined. Obtained data in digestibility experiments allowed on calculation of apparent absorption and retention of zinc and the level of Zn determined in tissues’ samples were used to the estimation of bioavailability of zinc from different ones applied in experiment sources. Apparent absorption and retention of zinc were higher (P≤0.01) in lambs receiving in mixtures amino acid complexes of zinc than in animals from the control group. The higher content of zinc in soft and hard tissues of lambs which received organic forms of zinc might indicate better assimilation and bioavailability of zinc from these forms than from oxide. Among tested organic forms of zinc, the zinc-lysine complex was characterized as having the most advantageous property.
