"The study was carried out to ascertain the effect of feeding water soaked rapeseed-mustard cake (RMC) based diet on the performance of lactating cows. Eighteen Holstein Friesian crossbred lactating cows were randomly allocated to 3 dietary treatments of 6 each viz. Control, RMC-dry and RMC-sani, respectively for an experimental period of 90 days. The glucosinolates (GLS) content of raw RMC was 149.50 µmol/g DM and it gets reduced by 31.96 per cent to 101.72 µmol/g DM in overnight water soaked (1:3 w/v ratio) RMC. The daily intake of concentrate and total DM by lactating cows did not differ significantly (Pgreater than0.05) irrespective of the dietary treatments. The digestibility coefficient (%) of DM, OM, CP, EE, NDF and ADF; nutrient density (%) and intake (g/kgW0.75) of composite diets in terms of DCP and TDN did not differ significantly (P>0.05) irrespective of dietary treatments. Milk yield and its basic quality parameters including milk fat, milk protein, total solids and SNF content were comparable among the dietary treatments. Though thiocyanate (CNS) concentration of blood serum (8.65 to 12.65 µg/ml) and milk (24.77 to 39.84 µg/ml) was significantly (P less than 0.01) increased in RMC fed groups as compared to control, it was significantly (P less than 0.01) reduced in RMC-sani as compared to RMC-dry. The serum T3 (2.07 - 2.15 nmol/L) and T4 (70.62 - 73.67 nmol/L) concentrations were comparable among the dietary treatments. Alongwith substantial reduction in the GLS content of water soaked RMC, no adverse effect could be noticed by feeding raw or water soaked RMC based diet on the performance of lactating cows and CNS excretion in the body fluids get reduced by dose dependent intake of dietary GLS.

Thirty-six lactating cows, after their first week on spring pasture, were subdivided into three groups of 12 cows each and assigned to one of three pelleted grain mixtures containing 0, 5 or 10% protected lipid. These grain mixtures were fed in the milking parlor at the rate of 1.0 kg/4.0 kg of milk yield for a period of 14 days and then the cows were switched to the next ration in the sequence. Milk yield and grain intake were recorded daily. Milk samples for fat, protein and lactose determinations were taken during the last week of the drylot feeding period, during the preliminary pasture period and on the last 2 days of each experimental period. The change in feeding system from drylot to pasture resulted in an average decrease of 0.65 and 0.10 percentage units in milk fat and lactose contents, respectively, and an increase of 0.27 of a percentage unit in protein content. Refusals of the grain mixture were greater (P < 0.05) but milk yields per kilogram of grain intake were higher (P < 0.05) for grain mixtures containing 10% protected lipid than for the control ration. Protected lipid was not effective in countering the milk fat depression caused by the onset of the spring grazing season. The feeding of protected lipid at the rate of 5 and 10% resulted in only a 10 and 27% recovery in total fat yield compared to cows fed the control ration.

The purpose of the research was to study the effectiveness of the use of rations for freshly calved cows during the increasing the milk yield period with the use of new mineral granulated complexes produced by Uralchem LLC. The results of research on the replacement of the mineral part of the vitamin and mineral premix in the rations of lactating cows with the mineral granular complex developed according to two recipes have been presented in the article. Research has shown that cows of the 1st and 2nd experimental groups during the experiment period gave more milk than their herdmates from the control group by 70,8 (P ≥ 0,95) and 106,2 kg (P ≥ 0,95). Due to the higher milk yield of animals that consumed the granulated complex, the yield of milk fat was greater than that of the control analogues by 3,21 (P ≥ 0,95) and 5,17 kg (P ≥ 0,95), protein by 2,70 and 4,30 kg (P ≥ 0,95). The milk yield of cows of the 1st and 2nd experimental groups for 305 days of lactation was higher than in the control group, respectively, by 205,3 (P ≥ 0,95) and 296,8 kg (P ≥ 0,95). In the milk of cows that consumed the granulated complex, there was a tendency for a higher content of dry matter (0,09 and 0,16 %), lactose (0,01 and 0,06 %), nonfat milk solids (0,09 and 0,07 %), ash (0,05 and 0,05 %) in comparison with analogues from the control group. A similar trend has been established between groups of cows in terms of milk density, acidity and rennet coagulability. The revenue from the sale of milk produced from cows of the 1st and 2nd experimental groups was more than in the control group for the experimental period (120 days) by 2074,6 and 3344,0 rubles and for the 305 days of lactation by 7055,4 and 9950,6 rubles.

Unbalanced mineral and vitamin nutrition of lactating cows can be a critical factor in the realization of their productive potential. The development and introduction into production of inexpensive, but effective feed additives is the main trend of improving the feeding of modern animal husbandry. Under the conditions of the Tyumen region such natural raw materials can be sapropels, which successfully combine a variety of biologically active substances. The purpose of the research was to study the digestibility of nutrients and energy metabolism in lactating cows when sapropel is included in the ration. Scientifi c and economic experiment in the study of the effectiveness of feeding sapropel lake Nepryak has been carried out in the training and experimental farm of the State Northern Trans-Urals Agrarian University. The animals of the control group have been fed the main diet. Cows of the 1st and 2nd experimental groups have been fed 300 and 500 g of sapropel per head/day, respectively, in addition to the main ration. It has been found as a result of research that the introduction of sapropel into the ration of cows has a positive effect on the digestibility of nutrients. The digestibility coefficients were higher in the animals of the 1st and 2nd experimental groups compared with the cows of the control group. Cows from the experimental groups digested all the organic substances of the ration better. During the experiment period cows of the 1st and 2nd experimental groups in contrast to the control group had higher milk yield by 11,31 and 10,38 %, respectively, milk protein yield by 10,56 and 5,95 %, milk fat yield by 17,18 and 12,99 %. It has been established that the introduction of sapropel into the ration of cows has the positive effect on the digestibility of nutrients, contributes to the increase of milk productivity, normalizes the metabolism in the body.

SUMMARYFour young females of four ruminant species, namely cattle, buffalo, sheep and goat, were fed, in chopped form, a mixture of species of dry grass (Apluda aristata and Themada quadvivalvis; 3·85% crude protein) during a 28-day experimental period. Voluntary intake of grass was determined during the last 10 days and digestibility of feed nutrients during the last 6 days.The digestibility coefficients of dry matter (D.M.) and crude fibre were higher for goats than other species, of organic matter, crude protein (CP) and ether extract were higher for goats and sheep than cows and buffaloes and of nitrogen-free extract higher for goats than cows and buffaloes and for sheep and buffaloes than cows. The daily intake of D.M., digestible CP and total digestible nutrients (TDN) is discussed in relation to body weight (BW) and kg W0·75.Dry grass fed with mineral and vitamin supplement was adequate to sustain the body weights of buffaloes and goats but not of cows and sheep. Buffaloes utilized the dry grass better than other species as is evident from the highest feed and TDN intakes and marginal gain in weight.

The aim of this study was to examine the behavioral, productive, reproductive and thermoregulatory performance of 3/4 and 7/8 Holstein/Gir (HG) dairy cows to identify which genetic composition suffers the least heat stress. A completely randomized design was adopted involving 20 multiparous, lactating crossbred cows from a dairy farm located in the municipality of Turvânia - GO, Brazil. During the experimental period, data on behavioral, productive, reproductive and thermoregulatory traits were collected every 15 days. Bioestat (5.0) statistical software was used for statistical analysis. The mean temperature-humidity index, ambient temperature and relative humidity obtained throughout the experimental period were 74.45, 30.51 ºC and 63.64%, respectively. In terms of reproductive performance, there was a significant difference (p < 0.05) between the genetic compositions for the time from calving to first service, with a longer period shown by the animals with greater Holstein breed genetic composition. Service period and calving interval differed significantly (p < 0.05) during the experimental period between the genetic compositions. A significant difference (p < 0.05) was also detected between the compositions for respiratory rate, with higher values observed in the animals with higher European genetic composition. Benezra thermal comfort index also differed significantly (p < 0.05), with the 7/8 HG animals showing a higher value. Lactating cows with a 7/8 HG genetic composition achieved better results in milk production, whereas those with 3/4 HG genetic composition showed superiority in milk fat composition and reproductive and thermoregulatory performance, indicating greater adaptation to the climatic conditions of the region.

A total of 160 crossbred weanling pigs [(Landrace × Yorkshire) × Duroc, 28 days old] with an initial bodyweight of 8.01 ± 0.74 kg were used in a 42-day trial (Phase 1: Days 1–14, Phase 2: Days 14–42). The experiment was conducted to evaluate the effects of the inclusion of fermented oats (FO) to a corn and soybean meal-based diet on the performance of weanling pigs fed with high nutrient-density (HD) and low nutrient-density (LD) diets. Pigs were randomly distributed into one of four dietary treatments in a 2 × 2 factorial arrangement. Two levels of nutrient density [LD = 3323 (Phase 1: 1–14 days) and 3269 kcal/kg (Phase 2: 14–42 days); HD = 3446 (Phase 1: 1–14 days) and 3325 kcal/kg (Phase 2: 14–42 days), the differences in dietary energy were based on differences in the content of fish meal, animal fat, corn and FO [0%, 5% (Phase 1) or 2.5% (Phase 2)] were used according to the bodyweight and sex of pigs [8 replicate pens per treatment with 5 pigs in a pen (3 gilts and 2 barrows)]. During the overall trial period (Days 1–42), the average daily gain and gain:feed ratio of pigs fed HD and FO diets were significantly higher (P ≤ 0.05) than those of pigs fed with LD and non-fermented oats diets respectively. On Day 14, the apparent total tract digestibility of dry matter and nitrogen of the HD groups were significantly greater (P ≤ 0.05) than those of the LD groups. The apparent total tract digestibility of energy of the FO groups was significantly greater (P ≤ 0.05) than that of the non-fermented oats diet groups during the whole experimental period. Pigs fed with FO showed higher (P ≤ 0.05) ileal Lactobacillus and lower (P ≤ 0.05) Escherichia coli counts compared with those fed with the non-fermented oats diet. In conclusion, administration of FO to a LD diet demonstrated beneficial effects on the growth performance, nutrient digestibility and ileal microorganisms balance of weanling pigs.

Four trials, each employing 10 cows were designed as 2 × 2 latin squares, with each experimental period consisting of a 1-wk preliminary period and a 4-wk period for data collection. The objective of the experiments was to determine the effectiveness of either sodium bicarbonate (NaHCO3), NaHCO3 plus magnesium oxide (MgO) or bentonite as buffers when they were mixed with corn silage just prior to feeding. The treatments compared were: Trial I, control vs. NaHCO3 (180 g·cow−1·day−1); Trial II, control vs. bentonite (300 g·cow−1·day−1); Trial III, control vs. NaHCO3 (180 g·cow−1·day−1) plus magnesium oxide (MgO, 60 g·cow−1·day−1) and Trial IV, NaHCO3 (180 g·cow−1·day−1) vs. bentonite (300 g·cow−1·day−1). Silage dry matter intakes (SDMI) were 10.61 vs. 10.93 and milk yields were 26.6 vs. 29.3 kg/day for control vs. NaHCO3 in Trial I; 10.03 vs. 10.39, and 29.5 vs. 30.1 for control vs. bentonite in trial II; 10.62 vs. 10.69, and 23.6 vs. 24.7 for control vs. NaHCO3 + MgO in Trial III and 11.49 vs. 10.79, and 29.4 vs. 29.5 for NaHCO3 vs. bentonite in Trial IV. In the latter trial cows fed silage supplemented with bentonite had significantly lower milk fat and protein percentages and rumen pH compared to those supplemented with NaHCO3. Similarly in Trial II cows fed bentonite had lower rumen pH and milk protein percentage than the control cows. It was concluded the bentonite did not act as a buffer and was not beneficial when added to corn silage just prior to feeding. NaHCO3 improved milk yield in one trial and milk fat percentage but the degree of response did not warrant its routine use as a supplement to corn silage. Key words: NaHCO3, MgO, bentonite, corn silage, lactating cows, buffers

SUMMARY1. The effect of feeding a salt solution containing ammonium acetate on the yield and fatty acid composition of cows' milk fat has been studied.2. The trials involved eighteen lactating Jersey cows. In the first trial one group of 5 cows was fed the treatment diet throughout an experimental period of 10 weeks and another group of 5 cows acted as controls. In the second trial which extended over four 28-day periods, two groups of 4 cows spent alternate periods on treatment or control diets. The overall results of the two trials were in agreement.3. The outputs of C4-C14 acids and of palmitic acid per kg of milk yielded were greater than the intakes. The output of C18 acids was less than the intake per kg of milk yielded. These observations were noted on both treatment and control.4. Treatment resulted in an increased secretion of C4-C14 acids and of palmitic acid and a decreased secretion of C18 acids per kg of milk yielded.5. The results have been discussed in the light of present knowledge concerning the synthesis of fat in the mammary gland.

The aim of the study was to evaluate the effect of extruded rapeseed cake in diets of dairy cows on changes in milk fatty acid profile and iodine content in milk and on the thyroid gland status. An experiment was carried out on four lactating Holstein cows divided into 2 groups – experimental (R) fed a diet based on extruded rapeseed cake and control (S) fed a diet based on extruded full-fat soya. The experiment was divided into 4 periods of 42 days (21 days of preliminary period and 21 days of experimental period). Samples of milk and blood were taken three times a week during the experimental period. DMI was not affected by the treatment (<i>P</i> > 0.05). Milk yield and 4% FCM were lower in R compared to S (<i>P</i> < 0.05). Percentages of milk fat and protein were higher in R than in S (<i>P</i> < 0.05). The total content of SFA and UFA was not affected by the treatment (<i>P</i> > 0.05). However, the content of MUFA in R was higher (34.71 g/100 g) and the content of PUFA was lower (4.00 g/100 g) than in S (32.14 and 5.54 g/100 g, respectively (<i>P</i> < 0.05). The contents of C18:2 and C18:3 isomers and metabolites in R were lower than in S (<i>P</i> < 0.05). The content of <I>cis</I>-9, <I>trans</I>-11 CLA and <I>trans</I>-10, <I>cis</I>-12 CLA was lower in R (0.71 and 0.016 g/100 g) compared to S (0.97 and 0.022 g/100 g, respectively, <i>P</i> < 0.05). The index of atherogenicity and peroxidisability in R was lower than in S (<i>P</i> < 0.05). The index of desaturation was not affected by the treatment (<i>P</i> > 0.05). The mean daily intake of glucosinolates (Gls) in R was 50.14 mmol and resulted in a significant decrease in iodine concentration in milk in R (196.7 &mu;g/l) in comparison with S (367.0 &mu;g/l, <i>P</i> < 0.05) resulting in the lower daily iodine output in milk in R compared to S (4.4 and 9.2 mg/day, respectively, <i>P</i> < 0.05). Concentrations of T<sub>3</sub> and T<sub>4</sub> in blood plasma were not affected by the treatment (<i>P</i> > 0.05).

An experiment was conducted with fifty four, 21 days old synthetic broiler (fifth generation) to study the effect of different levels of dietary protein on the performance of broiler during growing and finisher period. Three levels of protein i.e. T1 (18% CP), T2 (19% CP) and T3 (20%CP) were considered as the dietary treatments. The body weight achieved at 42 days of age was 1422.00, 1705.37 and 1563.67 gm in T1, T2 and T3, respectively which differs significantly (p< 0.01). The live weight gain at 42 days was also highest in T2 (19% CP) diet and significantly (p< 0.05) differed from T1 (18% CP) and T3 (20% CP) diets. Feed conversion ratios at the end of experimental period were 2.20, 1.75 and 1.87 in T1, T2 and T3, respectively which differs significantly (p<0.05). The performance index at 42 days of age was 50.66, 82.67 and 63.58 for T1, T2 and T3 respectively while feed consumption, livability and meat yield were not significantly (p>0.05) affected by dietary treatments. The net profit per kg live broiler was significantly highest (Tk.14.09/kg) (p<0.01) in T2 diet as compared to other treatments. It may be concluded that 19% crude protein diet, was the best with respect to growth, FCR and net profit for synthetic broiler (fifth generation) during growing and finisher period.DOI = http://dx.doi.org/10.3329/bjvm.v8i2.11193 Bangl.
