AbstractThe aim of this work was to study the effect of the contemporary administration, in separate troughs, of two diets differing in digestible energy (DE) and crude fibre (CF) content, on the performance of lactating rabbit does. At the first mating (130 days of age and 3·8 kg), 54 nulliparous rabbit does (New Zealand) were assigned to the control group offered a conventional lactation diet (diet C: 188 g crude protein (CP) per kg dry matter (DM) and 11·43 MJ DE per kg DM); whilst another 54 rabbit does were offered at the same time, in separate troughs, diet E (203 g CP per kg DM and 12·66 MJ DE per kg DM) and diet F (178 g CP per kg DM and 10·73 MJ DE per kg DM). The contemporary administration of two diets did not significantly affect food intake. However, the rabbit does in group F + E, due to the greater consumption of diet E (approx. 0·76 of the total), consumed more digestible protein (DP) both during the first (14·40 v. 13·44 g/day per kg M0·75 and 80·1 v. 73·5 g/day per kg M0·75, respectively for days 1 to 21 and days 22 to 35) and subsequent lactations (15·37 v. 14·35 g/day per kg M0·75 and 82·6 v. 76·5 g/day per kg M0·75 respectively for days 1 to 21 and days 22 to 35). Also the DE intake was higher for the rabbit does of group F + E during the 22- to 35-day period (6708 v. 6361 kJ/day and 6918 v. 6620 kJ/day respectively for primiparous and multiparous). The improved performance of rabbit does given two different diets does not justify the extra time involved in such a technique, as the intake of diet E was constant during the experimental period and was not influenced by the different energy requirements during lactation.

An experiment was carried out to evaluate two temperate forage legumes (Trifolium pratense and Trifolium repens) and two tropical forage legumes (Stylosanthes guianensis and Centrosema molle) for hay intake and digestibility in the cool tropical climate of Vom, Jos, Plateau State of Nigeria. The legumes were planted in the month of June, 2016 and harvested at early-podding stage for hay. Sixteen (16) growing male New Zealand White rabbits were used for the digestibility study. The rabbits were arranged in a Completely Randomised Design and in individual cages measuring 55 cm x 39 cm x 40 cm. Nutrient contents, intake and digestibility in rabbits were determined. Crude protein content was significantly (P<0.01) higher in T. repens (18.38%) compared to T. pratense (16.50 %), whereas S. guianensis produced the least value of 13.83%. The crude fibre content of the hay was significantly higher (P<0.0I) in S. guianensis (37.29 %) compared to the other forage legumes. Dry matter intake was significantly (P<0.01) higher in rabbits fed T. repens (77.88%) compared to T. pratense (76.57%), and the lowest value of 62.97% was obtained in S. guianensis. Crude protein intake was significantly (P<0.01) higher in rabbits fed T. repens (15.05 g d-1) compared to those fed T. pratense (12.71 g d-1), but S. guianensis had the least value of 8.64 g d-1. On the other hand, rabbits fed S. guianensis hay had a higher (P<0.01) crude fibre intake (23.39%). Trifolium repens was significantly (P<0.01) higher in dry matter and crude protein digestibility (64.79 and 85. 88 %), while S. guianensis had lower values of 56.89 and 71.33%, respectively. Trifolium repens also had a significantly (P<0.01) higher total nitrogen intake and retained compared to the other forage legumes. Nitrogen retained in T. repens was 2.40 g d-1 compared to 1.87 g d-1 in T. pretense, while S. guianensis had the lowest of 1.34 g d-1. The temperate forage legume hays were higher in nutrient content, intake and digestibility compared to the tropical legume hays. Therefore, the forage crops may serve as better supplementary feeds for livestock feeding especially during the dry season.

The analysis of the literature data shows that there is not enough information on the enrichment of the ration of cows of Black-and-White breed with a balanced feed complex Felucen K 1–2 that has caused the relevance of our researches. The purpose of the research was to increase the productive qualities of cows Black-and-White breed when using different doses of the balanced feed complex Felucen K 1–2 in their ration. The studies have been carried out in the Southern Urals, the optimal dose of use of feed complex Felucen K 1–2 that enhance milk productivity of cows of Black-and-White breed. According to the scheme of the experiment cows of the 2nd, 3rd and 4th experimental groups have been additionally fed to main ration 300 g, 350 and 400 g of the balanced feed complex Felucen K 1–2, consisting of vegetable protein and fat, easily fermentable carbohydrates, high-purity sodium chloride, macronutrients, trace elements, and vitamins. Animals of the 1st group have been served as control and complex Felucen have not been received. Studies have shown that cows of the 1st control group used less dry matter, EFU, metabolic energy, digestible protein, crude protein, crude fiber, and crude fat than their experimental herdmates. Thus, the superiority of cows of the experimental groups over the herdmates of the 1st control group in terms of EFU was 93,1–231,2 kg; metabolic energy – 933,7–2314,7 MJ; dry matter – 9,0–125,8; digestible protein – 8,9–29,7; crude protein – 4,6–18,3; crude fiber-13,1–48,4; crude fat – 11,6–21,0 kg. Animals of all experimental groups in comparison with the control group exceeded in terms of milk yield for 305 days of lactation by 435,2 kg or 6,60 % (P < 0,001); 814,4 kg or 12,34 % (P < 0,001); 684,1 kg or 10,37 % (P < 0,001); for 100 days of lactation – by 98,7 kg or 4,28 % (P < 0,001); 191,0 kg or 8,29 % (P < 0,001) and 167,8 kg or 7,28 % (p<0,001), respectively. The use of Felucen K 1–2 feed complex in the rations of lactating Black-and-White cows has shown its effectiveness, which has affected the feed consumption and effectiveness of their use, hematological indicators, the level of milk productivity and milk quality. From an economic point of view the dose of 350 g of balanced feed complex Felucen To 1–2 per animal per day is more reasonable.

1. Ayr Line Potato oats was studied in the later stages of development for 3 years under upland conditions in Kincardineshire, Scotland. Some major changes in yield and chemical composition of the crop and certain effects of haymaking have been demonstrated.2. In each year, between the ‘milky’ stage and full ripeness of the grain, the growth curve falls into the distinct phases of growth, maturity and senescence when dry-matter loss occurs. The position of the peak yield in terms of stage of maturity varies from year to year.3. Percentage crude protein is low throughout, falling to a minimum after the early ‘milky’ stage and rising again to a maximum at the last cut. Yield of crude protein is highest at the last cut in one year and at the penultimate cut in two years.4. Percentage crude fibre tends to decrease with increasing maturity, while crude fibre yield is low at both extremes of the experimental period.5. More detailed chemical analyses at different stages of maturity show total ash content to be low. The content of calcium is especially poor.6. Separation of the whole of the aerial part of the plant into leaf, stem and inflorescence shows that chemical constituents are being actively re-distributed throughout the plant during the experimental period; with the exception of crude fibre and calcium all constituents estimated tend to be concentrated in the grain with advancing maturity.7. In one year, dry-matter losses during curing range from 22 to 7% at the first and last cuts respectively, while corresponding figures for crude protein are 18 and 10%.8. In the absence of digestibility data and feeding trials under Scottish conditions, the tentative conclusion is drawn that in the higher rainfall areas of the north and west where the crop is most likely to be used, cutting between the late ‘milky’ and late cheesy' stages should give optimum results.9. Attention is drawn to the need for caution in the general application of the results.

An experiment to compare the effects on digestibility of alkali treated Gamba grass (Andropogon gayanus) straw was conducted with four Borno white male goats (22.25 ± 1.0kg body weight) in a 4 x 4 Latin square design. Treatments were (A) untreated straw (control), (B) Sodium hydroxide (NaOH) treated straw, (C) Kanwa-treated and (D) Kantu-treated straws. Straw was treated separately with solutions (8%) of NaOH, Kanwa and Kantu for 10 minutes prior to ensiling for 20 days. In treatment A, straw was soaked in water before ensiling. Alkali treatment increased the ash and crude protein, but decreased the crude fibre, nitrogen free extract and energy contents of the silage diets. The ether extract content of the diets was not affected by treatment. Dry matter intake (g/day/Wkg ) of alkali treated diets was significantly higher (P<0.05) than the control The NaOH-treated diet was consumed less (P<0.05) than the Kantu-treated diet, but to the same extent as the Kanwa diet. Nitrogen balance was positive in animals consuming the alkali-treated diets and negative for those in the control group. Apparent N-digestibility were similar in the alkali treated diets and better (P<0.05) titan in the control. Digestibility coefficients of dry matter, crude protein and crude fibre were not significantly different among the alkali treated diets. However, they were markedly improved (P<0.05) than in the control diet (A). The results indicated that the natural alkali sources (Kanwa and Kantu) compared favourably with NaOH in improving the nutritive value of Gamba grass hay. Further work however should be undertaken to ascertain the optimal level of their application under the semi-arid environment of Borno State.

The influence of supplementation of a lecithin emulsifier (0.1%) to the feed mixture for piglets after weaning was studied. 16 piglets in the control group (C &ndash; without lecithin) and 16 piglets in an experimental (E) group were monitored in three replications in a 28-day experimental period. We observed higher digestibility of monitored nutrients in the experimental group (crude fat: C = 66.28 &plusmn; 12.11, E = 69.75 &plusmn; 9.85%, crude protein: C = 78.72 &plusmn; 5.47, E = 82.17 &plusmn; 2.23%, crude fibre: C = 56.70 &plusmn; 12.85, E = 59.10 &plusmn; 12.04%, nitrogen free extract: C&nbsp;=&nbsp;86.67 &plusmn; 3.32, E = 87.75 &plusmn; 3.00%, ash: C = 63.63 &plusmn; 11.59, E = 65.73 &plusmn; 10.35%). Statistically insignificantly higher daily average gain (C = 374.1 &plusmn; 107.0, E = 399.1 &plusmn; 104.7 g) of experimental groups and a lower feed conversion ratio (C = 2.285 &plusmn; 0.416, E = 1.768 &plusmn; 0.048 kg/kg) were found out. It was also confirmed in an additional field experiment (C = 279, E = 312 piglets from birth to 71 days of age) where average daily gain weight was 270 g in control and 290 g in experimental group. The influence of lecithin on the occurrence of haemolytic strains of Escherichia coli was not proved. This experiment confirmed a positive effect of the lecithin emulsifier supplement on the efficiency of piglets. &nbsp;

Abstract. The current study examined the effects of probiotics (Pronifer and More-yeast) supplementation to growing lambs. 25 crossbred (Osimi×Rahmani) growing lambs of about 6–8 months age and an average initial live body weight of 25 kg were used. Lambs divided into five groups (5 lambs for each group) and the experimental period lasted for 169 days. The control group T1 received concentrate feed mixture (CFM), group T2 and T3 received 1.5 and 3 kg Pronifer/Mg (megagram) CFM and group T4 and T5 received 2.5 and 5 kg More-yeast/ Mg CFM, respectively. Rumen liquor and blood samples were taken and digestibility trial was conducted at the end of the experiment. Results showed higher digestibility values for crude protein (P<0.05) in T3 and T4 when compared to control. Nutritive ratio was lower (P<0.05) in groups T3 and T4 than in group T2. More-yeast supplementation improved dry matter intake (P<0.001), while a reverse trend was observed with Pronifer supplementation. All treatments had little effect on ruminal liquor except ruminal ammonia concentration in T5 was lower (P<0.05) than other treatments. The differences in most blood plasma parameters due to treatment effect were not significant, except plasma urea and globulin concentrations increased (P<0.05) with T5 treatment. The obtained results appear to indicate that Moreyeast supplementation improved lambs performance and digestibility, whereas, Pronifer supplementation enhanced digestibility.

1. Twenty cows were used in an experiment to compare the effect of five different diets on the fat and solids-not-fat content and yield of milk.2. During initial and final control periods all the cows received 18 lb. hay daily and about 4 lb. of a balanced concentrate mixture (crude protein 16·5%) per 10 lb. of milk produced. In the experimental period, which lasted 7 weeks, a control group of four cows remained on this diet. Two similar groups received daily only 4 lb. hay and about 6 lb. extra concentrates; in these groups the concentrates contained 22·3% crude protein. The remaining two groups received similar treatment except that the concentrates contained only 11·6% crude protein. In addition, 10 1b. macerated delignified straw pulp (containing 1 lb. crude fibre) were given to half the cows receiving each type of concentrate. At the end of the experiment the cows were turned out to grass.3. With the diets low in hay and high in concentrates there was a fall in the fat content of the milk, with some variability in the response of individual cows (see 4 below). With the concentrates high in protein, the fall appeared to be rather slower than with those low in protein, but by the sixth and seventh weeks of experimental treatment it was estimated to be 0·67% fat with high and 0·72% fat with low protein concentrates. The experiment showed, therefore, that serious falls in fat content may occur in cows early in lactation with diets of 4 lb. hay and concentrates containing 22·3 or 11·6% protein. The addition of a limited amount of crude fibre as straw pulp brought about no recovery in milk fat content.4. The extent of the depression brought about by the change to diets low in hay diminished with advancing stage of lactation.

По результатам научных исследований, выполненных за ряд лет в растениеводстве и животноводстве, показана целесообразность интродукции в кормопроизводство Пермского края новой многолетней бобовой культуры эспарцета песчаного. По четырёхлетним наблюдениям (2012 2015 годы) в полевых опытах культура не уступала по урожайности кормовой массы традиционному для региона клеверу луговому, а по концентрации обменной энергии и сырого протеина в сухом веществе была на уровне клевера лугового и люцерны изменчивой, но в разы превосходила их по содержанию сахара. Сенаж это единственный вид зимнего корма, максимально сохраняющий обменную энергию, протеин, сахар, каротин, достаточно концентрированный, чтобы обеспечивать потребности высокопродуктивных животных. В 2018 году на Лобановском молочном комплексе ООО Русь в Пермском районе Пермского края были проведены научнохозяйственный и физиологический опыты по скармливанию сенажа из эспарцета песчаного голштинизированным коровам чёрнопёстрой породы. При использовании сенажа из эспарцета песчаного животные в сутки потребляли сухого вещества на 2,3 3,9 кг на голову больше по сравнению с группой, где в рационе было сено (контроль). В результате использования сенажа из эспарцета песчаного переваримость сухого вещества рациона у опытных групп животных была выше на 2,55 5,80 по сравнению с контрольной органического вещества на 2,54 4,14 . За учётный период научнохозяйственного опыта (120 дней) от коров опытных групп получено по 399327,2 и 414431,9 кг молока, что со средней степенью достоверности выше продуктивности животных контрольной группы (391045,4). По содержанию молочного жира и молочного белка преимущество достоверно также было за опытными группами. Затраты корма на 1 кг молока составили в контроле 0,74 энергетических корм. ед. (ЭКЕ), в опытных группах 0,71 и 0,69 ЭКЕ. Hungarian sainfoin was shown to be an effective perennial legume crop in the forage production of the Perm Territory. For 4 years (2012 2015) this crop produced forage mass, exchange energy and crude protein comparable to the ones of red clover and bastard alfalfa but exceeded them significantly in carbohydrate content. Haylage is the only type of winter forage that has sufficient concentrations of exchange energy, protein, carbohydrates and carotene, satisfying needs of highproductive livestock in nutrients. Haylage from Hungarian sainfoin was fed to Holstein BlackandWhite cows in the frame of experiments conducted in 2018. Cows consumed 2.3 3.9 kg more of dry matter (DM) with the haylage, compared to hay (control). Digestibilities of DM and organic matter were 2.55 5.80 and 2.54 4.14 higher than in the control group, respectively. For 120 days the experimental groups produced 3993 27.2 and 4144 31.9 kg of milk versus 3910 45.4 kg of the control one. The former also exceeded the latter in milk fat and protein contents. Fodder costs per 1 kg of milk amounted to 0.74 energy feed units in the control and 0.71 and 0.69 energy feed units in the experimental groups.

Obesity is a common problem in cats. In the experimental cat family of the institute of animal nutrition besides a “normal” lean phenotype, cats with predisposition to an overweight phenotype are present. To investigate energy requirements and food intake behaviour of intact male cats of different phenotypes, six “normal” lean cats (GL) and six cats disposed to overweight (GO) were used. At the beginning of the experiment, all cats had an ideal body condition score of 5. To reach this the GO cats had to pass a weight-loss program. Energy requirements of the cats were determined using respiration chambers, whereas the amount and frequency of food intake was measured with a feeding station recording the data automatically. Energy requirement at weight constancy of the GO cats was even on fat-free mass (FFM) significantly (P=0.02) lower (162.6 kJ/kg FFM/d) than that of the “normal” lean cats (246 kJ/kg FFM/d). The GO cats also showed a higher food intake34.5±1.5 g dry matter/kg body weight0.67compared to the GL cats (24.0±2.1 g dry matter/kg body weight0.67)(P=0.001). In conclusion quantifiable differences in food intake and behaviour in cats predisposed to overweight compared to “normal” lean cats were found.
