Nutrients Digestibility

The aim of the present study was to evaluate the effect of replacing concentrate feed (CFM) mixture with different levels of treated lemon pulp (TLP) on milk production and composition, nutrients digestibility, and blood parameters of Zaribi goats. A total of 24 Zaribi female goats at the end of the pregnant period were divided into three groups of eight according to live weight. Concentrate feed mixture and clover hay at a rate of 50:50 were offered twice a day. Treatedlemon pulp replaced CFM at rates 0%, 25%, and 50 % in diets of R1, R2, and R3 treatment groups, respectively. The feeding trial lasted 90 days. Dry matter digestibility and Nitrogen free extract digestibility were significantly raised by the increased level of TLP in groups R2 (72.37% and 70.36%) and R3 (72.28% and 70.30%), compared to (70.99% and 68.51%) in R1, respectively. The same trend was observed for organic matter digestibility (OMD), crude protein digestibility (CPD), crude fiber digestibility (CFD), and ether extract digestibility (EED) with R3, compared with either R1 or R2. However, there were insignificant differences between R1 and R2 in terms of OMD, CPD, and EED but CFD was significantly higher in R2, compared to R1. There was a significant increase in the milk yield by the increased level of TLP in the diet and for R2 (1448.4g/h/d) and R3(1558.7g/h/d), while it was reported as 1377.6 g/h/d in the control group. Feeding dams on the R3 diet had a significant effect on improving total antioxidant capacity by 63.5%, compared with control. The results of the present study indicated that the replacement of CFM by TLP decreased the costs of feed and increase milk production for the replacement level by 50% (R3). Moreover, no adverse effects were noticed on nutrients digestibility and blood parameters of the investigated samples.

The paper presents testing results of feeding dry cows and horses with cryo-feed, preserved by using natural techniques, at winter grazing (tebenevka). Research into digestibility of nutrition substances of cow ration was carried out on 30 cows of Sirrrmental breed divided into three groups (control and two experimental ones, whose ration included 4 and 1.5 kg of cryo-feed respectively). The introduction of cryo-feed in the ration of cows increased the level of metabolizable energy and had a positive impact on the efficiency of energy metabolism. Cows of the 1 st experimental group, where cryo-feed accounted for 12% of the nutrition ration, showed 5.8% higher protein digestibility than the control group. Feeding cows with cryo-feed in the dry period contributed to the maintenance of reproductive qualities. The percentage of fertilization of cows was 90-100%. It was established that feeding horses on cryo-feed significantly increased their nutritional level at tebenevka in the winter time and fully met the need of animals in feeding elements. This marked a high horse feeding capacity per 1 ha of cryo-feed, which amounted to 129-142 horse days. The advantage in organic matter digestibility at tebenevka on cryo-feed accounted for 11.9%, dry matter - 10.48%, crude protein - 18.3%, crude fiber- 21.9%, crude fat - 13.3%, and nitrogen-free extractive substances - 11.7%. The energy supply of a horse organism per 100 kg of live weight was 32.6 MJ, which exceeded the norm by 14.5%. Better digestibility of nutrients of winter-green mass of oats compared to the grass stand was due to the high content of carotene and provitamin Е in plants preserved on the root by natural cold. During the study it was established that the actual foal crop increased by 12-14% at tebenevka with horses on cryo-feed compared to traditional technology.

SUMMARYSixty-four young male Sudan desert lambs were group-fed for 87 days on four diets, all containing approximately 10% crude protein. The four diets contained 0, 1·3, 1·7 and 2·7% urea, respectively.Average daily gains were 0·15, 0·14, 0·14 and 0·13 kg; feed conversion ratios (kg of feed required to produce 1 kg live-weight gain) were 7·26, 8·14, 8·92 and 7·92; dressing percentages were 43·6, 42·1, 44·1 and 42·3.Digestibility trials with lambs fed on diets with 0 or 2·7% urea gave higher digestibility coefficients for crude fibre and nitrogen-free extract for the urea-supplemented lambs. Crude protein digestibility and nitrogen retention values were lower for urea-supplemented lambs.

AbstractTwenty-nine Holstein-Friesian and 20 Norwegian dairy herd replacements were used to investigate the effect of habituating heifers to the milking parlour environment prior to calving on subsequent lactational performance. The heifers commenced the study at 3 weeks prior to calving when they were allocated on the basis of breed, genetic merit and live weight to either a habituation or no habituation (control) treatment. Heifers were housed together in cubicle accommodation with grass silage offered ad libitum along with 1 kg of concentrates per head per day offered in the feeding passage (control treatment) or in the food managers in the milking parlour (habituation treatment). Animals in the habituation treatment were exposed to the full milking parlour routine once daily (afternoon milking) in a 20-point rotary herringbone parlour. Holstein-Friesian heifers averaged 2.6 kg/day more milk than the Norwegian replacements. Holstein-Friesian heifers also had higher fat and protein yields than Norwegian heifers, however they also lost more body condition during the first 3 months of lactation. Habituated heifers yielded on average 1.3 kg/day more milk (P < 0.001) than the control group of heifers over the first 100 days of lactation (26.7 v. 25.4 (s.e.d. 0.38) kg/day), with the difference being greatest in the first 2 to 3 weeks of lactation. In early lactation, animals on the habituation treatment lost more live weight (0.16 v. 0.02 (s.e.d. 0.061) kg/day) (P < 0.05) and body condition than those on the control treatment. Duration of milking was longer (P < 0.001) (378.4 v. 340.5 (s.e.d. 6.53) s) and milk flow rate slower (P < 0.001) (2.20 v. 2.46 (s.e.d. 0.041) kg/min) respectively for the habituation compared with control group. Somatic cell counts (SCC) were lower (P < 0.001) for habituation group (1.66 v. 1.79 (s.e.d. 0.037) log10SCC per ml), but there was no significant treatment effect on locomotion scores. Reproductive performance was lower for habituated heifers, with increased intervals to conception (P < 0.05) (102 v. 83 (s.e.d. 9.22) days). Habituating heifers to the milking parlour environment prior to calving increased milk production but appeared to have some detrimental effects on reproductive performance.

In this study, it was investigated the effect of clove oil supplementation at increasing levels into laying hens’ diets on performance, egg quality traits, some blood parameters and yolk TBARS (Thiobarbituric Acid Reagent) values. For this purpose 96 Lohman white laying hens, 28 weeks of age, were divided into four treatment groups. Control group was fed with basal diet (C) and treatment groups were fed with diets formed by addition of clove oil at 50 ppm (CO1), 100 ppm (CO2) and 150 ppm (CO3), respectively. During the trial, feed and water were given as ad-libitum, and poultry house was illuminated for 17 hours. Experiment lasted for 13 weeks. Addition clove oil at increasing rates into diet did not affect the live weight. The data analysed as polynomial showed that supplementation of clove oil into layer diet linearly improved feed conversion ratio and increased the egg production. But, daily feed consumption, egg weight, damaged egg ratio and egg quality parameters were not affected by treatments. Serum parameters such as triglyceride, glucose, aspartate aminotransferase, alanine aminotransferase and calcium were not affected by the clove oil supplementation. TBARS values in C, CO1, and CO2 were found higher than the CO3 group fed with diet including 150 ppm clove oil. In conclusion, clove oil at 150 ppm level in diets of laying hens could be used due to extend the egg shelf life and to decline serum cholesterol content.

In the modern world the technology of production becomes a decisive factor in the growth of the economic potential of all branches of animal husbandry, a profi table direction and object of application of capital and resources, an instrument of competition. Technology determines the level of intensity and effi ciency of production, its environmental safety, production quality, biological and nutritional value of food. In recent years, highly productive cattle of Black-and-White breed with a high proportion of blood of Holstein breed are used to produce milk. For expression of their genetic potential of productivity it is necessary to work out technology of rearing of replacement heifers as it is known that conditions of rearing have essential infl uence on further productivity of animals. From one-year-old heifers and heifers to 6-month pregnancy, the control group has been housed in a cell-group method on slotted cast-iron fl oors, and the experimental group has been housed in a loose-boxes technology. Diff erent ways of housing had an impact on the growth and development of animals. Heifers of the experimental group in the fi rst period of research from 12 to 15 months had a lower absolute gain in body weight, which has been associated according to our opinion with the stressful situation from the habituation of animals to each other, since the number of animals in the group has been increased by 2 times. However, by 18 months of age the live weight of heifers in the experimental group has reached the live weight of heifers in the control group, while they had a higher average daily gain by 45,1 g (P < 0,05). Further, the heifers of the experimental group were superior to the heifers of the control group. It has been established that the loose-boxes method of housing allows to increase labour productivity and accordingly the effi ciency of milk production.

AbstractThirty-six 5-month-old Dorset ram lambs (28·7 kg) were used to investigate the effects of fasting and transport on performance and selected blood parameters. Three treatment groups (no. = 12) were: (1) control-food and water, without transport; (2) fasting for 72 h, without transport; and (3) transport in a trailer to a nearby auction-barn, then driven 8 h/day for 3 days without food or water for a total of 72 h. Lambs were given a total mixed diet containing 163 g/kg crude protein throughout the 28-day post-transport period. Both fasted and transported lambs consumed less food than the control group during the first 7 days post treatment (P < 0·05). Water intake was similar for all treatment groups on the 1st day post transport, after which both fasted and transport lambs drank less ivater than control lambs during the following 6 days (P < 0·05). Live-weight loss after the 3-day fast and transport period and subsequent body-weight gain during the 28-day realimentation period differed across all treatment groups (P < 0·05 and P < 0·09; (1) 1% and 305 g, (2) 14·8% and 343 g, and (3) 20·0% and 390 g, respectively, though control lambs had the highest weight gains over the 32-day experimental period. Plasma urea nitrogen was lower in both fasted and transported lambs on days 6, 7 and 11 compared with control lambs (P < 0·05). Plasma glucose concentrations on days 4 and 5 were lower in transported lambs than in fasted lambs, and highest in control lambs (P < 0·05); glucose concentration levels remained lower in both fasted and transported lambs than in control lambs on days 6 and 7 (P < 0·05). Plasma cortisol concentrations were highest in transported lambs during the 3-day transport period and for 2 days immediately following transport (P < 0·05). Effects of the 72 h fast were exacerbated by auction barn activity and subsequent transport, and compensatory gains by fasted and transport lambs were incomplete within the 28-day post transport period.

The article analyses the issues of balanced feeding of broiler chickens and their balanced diet. The results of studies aimed to determine the effect of mixed feeds on the productivity of Arbor Acres cross broiler chickens and the economic efficiency of poultry meat production companies are presented. It was found that broilers from the experimental group, who were fed with improved compound feed with additional sources of proteins and carbohydrates and feed additives exceeded broilers from the control group by their live weight at all ages. At the slaughter age, the average weight was more than 39.2%. The experimental group consumed 10-15% less feed whose conversion was 2.4 and 1.9 kg in favour of the group feeding with the new compound feed. The new compound feed had a positive effect on the viability of broilers: there were no deaths during the period under study. According to the control slaughter results, it was found that the pre-slaughter live weight was higher by 35% in the experimental group. The weight of edible parts increased by 6%. The improved compound feed can be used both in industrial conditions and by poultry farms.

<p>The purpose of this study was to compare the effect of dietary zinc from inorganic and organic sources on the concentration of Zn, Cu, Mn and Fe in plasma, tissues and faeces of rabbits. Simultaneously, the activities of total superoxide dismutase (SOD), specific Cu/Zn SOD, glutathione peroxidase (GPx), lipid peroxidation and total antioxidant capacity (TAC) in liver and kidney were also determined. Ninety-six 49-day-old broiler rabbits were allocated to 4 dietary treatments, each replicated 6 times with 4 animals per replicate. For the subsequent 6 wk, the rabbits were fed an identical basal diet (BD) supplemented with an equivalent dose of Zn (100 mg/kg) from different sources. Group 1 (control) received the unsupplemented BD, while the BD for groups 2, 3 and 4 was supplemented with Zn from Zn sulphate, Zn chelate of glycine hydrate (Zn-Gly) and Zn chelate of protein hydrolysate (Zn-Pro), respectively. The intake of dietary Zn sulphate resulted in an increase in Zn plasma concentration (1.85 vs. 1.48 mg/L; <em>P</em>&lt;0.05) compared to the control group. Feeding the diets enriched with Zn increased the deposition of Zn in the liver (<em>P</em>&lt;0.05), irrespective of the Zn source. The addition of Zn-Pro resulted in significantly higher Cu uptake in liver (<em>P</em>&lt;0.05) than in the control and Zn sulphate group (56.0 vs. 35.0 and 36.7 mg/kg dry matter (DM), respectively). Neither Mn nor Fe concentration in plasma and tissues were affected by dietary Zn supplementation, with the exception of Fe deposition in muscle, which was significantly decreased (<em>P</em>&lt;0.05) in rabbits supplemented with inorganic Zn sulphate compared to control and Zn-Gly group (9.8 vs. 13.3 and 12.2 mg/kg DM, respectively). Intake of organic Zn-Gly significantly increased the activities of total SOD (43.9 vs. 35.9 U/mg protein; <em>P</em>&lt;0.05) and Cu/Zn SOD (31.1 vs. 23.8 U/mg protein; <em>P</em>&lt;0.01) as well as TAC (37.8 vs. 31.2 μmol/g protein; <em>P</em>&lt;0.05) in the kidney when compared to that of the control group. The presented results did not indicate any differences between dietary Zn sources in Zn deposition and measured antioxidant indices in rabbit tissues. Higher dietary Zn intake did not cause any interactions with respect to Mn, Cu and Fe deposition in liver and kidney tissues, but did increase the faecal mineral concentrations. Dietary organic Zn-Gly improved the antioxidant status in rabbit kidney.</p>

Abstract The objective of this study was to determine the impact of dihydroquercetin from Siberian larch and dry distilled rose petals (DDRP) on growth performance, carcasses characteristics and blood parameters of lambs from the Bulgarian Dairy Synthetic population sheep. For the purpose of the study there were used 30 clinically healthy male lambs aged 65 days, levelled by live weight. They were housed in a totally indoor barn and were divided into one control and two experimental groups, each consisting of 10 animals that were fed for 50 days. The control group (C) was fed ground alfalfa + granulated compound feed. The experimental groups (D) and (R) were fed on the same diet supplemented either with 7.5 mg dihydroquercetin/kg/day or with 545 mg DDRP/kg/day respectively. The carcass yield of lambs having consumed dihydroquercetin or DDRP compared to lambs from control group C do not have significant differences (p > 0.05). The carcass conformation of C or R groups lambs do not differ (70% - class P, 30% - class O). The 90% of lamb's carcasses from the experimental group D were classified in class P. The dihydroquercetin feeding increases the relative fat content (p ≤ 0.01) of lamb carcasses but adversely affects their conformation. No significant differences (p > 0.05) were found between 1st h and 24th h post-mortem pH of control group C and experimental group D. Compared to them the pH values of the experimental group R were by 0.14-0.15 pH units lower (p ≤ 0.05). No significant differences (p > 0.05) were found in the blood count of the three studied groups of lambs. Exceptions were made for haemoglobin (HGL) in the experimental group D which were with 6-7 g/l higher (p ≤ 0.05) than these in control group C and experimental group R and the blood glucose (GLU) in the experimental group R which is with 0.25-0.28 mmol/l lower than determined in control group C and experimental group D.
