The objective of this study was to determine the effect of spineless cactus incorporation in food of dairy goats and growing kids on milk production and composition and on kid's growth and meat characteristics. Two experiments were conducted on Tunisian local goats. In the first, 30 females were divided into two groups; goats of Control group were reared on grazing pasture receiving indoor 0.5 kg of hay and 0.4 kg of concentrate. Goats for the second group (Cac-FL) were kept in feedlot and fed cactus ad libitum more 0.5 kg of hay and 0.4 kg of concentrate. In the second experiment, 14 kids were divided into 2 groups receiving 600 g of hay. The Control group received ad libitum a concentrate containing 130 g crude protein (CP) per kg of dry matter. The second group received cactus ad-libitum plus the half concentrate quantity of control one with 260 g CP/kg DM (Cactus). The daily milk production averaged 485 ml for Control group and 407 ml for Cac-FL one. The milk fat content was significantly higher for Control than Cac-FL group. In the second experiment, animals in Control and Cactus groups had similar growth rate. Carcass fat was significantly lower in Cactus than in the Control group. Cactus in the diet was associated with more C18:2 and conjugated linoleic acid as well as a higher proportion of PUFA than Control ones.

Two feeding regimes were compared using 13 lactating cows (11 Holstein- Fresian and two Brown Swiss) confined in corrals. The rations consisted of a conventional concentrates mixture and sorghum silage in treatment A, and of 22.5 percent sugarcane bagasse mixed with 20.0 percent molasses and 57.5 percent other concentrates (complete ration) in treatment B. The experimental design was a double-reversal with 10-week periods, each divided into a 3-week adjustment and a 7-week comparison phase, preceded by a 25-day preliminary period. During the 7 weeks of the comparison phase of the first of the three experimental periods, five cows on treatment A averaged 37.0 pounds of concentrates and 30.5 pounds of silage consumption daily, while eight cows on treatment B consumed an average of 48.0 pounds of the complete ration. Average daily milk production with these respective rations during the comparison phase in question was 53.1 and 56.9 pounds. No significant differences between treatments were found. Over the three experimental periods of the double-reversal, daily intakes averaged 36.6 pounds of conventional concentrates mixture, 30.2 pounds of silage, and 45.1 pounds of complete ration. On treatments A and B, daily milk production averaged 48.6 and 47.4 pounds; milk fat percentage, 2.85 and 3.23; milk solids-notfat percentage, 9.08 and 9.03; milk total solids percentage, 11.92 and 12.26; milk protein percentage, 3.53 and 3.43; and daily liveweight gain, 1.15 and 1.01 pounds, respectively. The difference between treatment means was significant for milk fat (P < .01) and milk total solids (P < .05) percentages. Since the complete ration resulted in productive performance comparable to that obtained with ad libitum consumption of conventional concentrates, it is concluded that the former is capable of sustaining milk production at nearly maximum capacity. Milk production on treatment B was also equal to that obtained in a previous experiment with a complete ration containing 7.5 percent less bagasse and 5.0 percent less molasses, and correspondingly higher proportions of soybean meal and shelled corn.

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.

The aim of research was to study the effect of different amounts of cobalt citrate produced by nanotechnology on biochemical processes in cows, their productivity and biological value of milk in the first two months of lactation. To achieve this goal the subsequent problems have been solved. We investigated the effect of different amounts of cobalt citrate on biochemical parameters of blood and milk of cows and controlled their average daily yield. The experiment has been conducted in 3 groups of cows (5 cows each) of Ukrainian black and white dairy cattle, analogue by body weight (590–620 kg), performance (6,5–6,8 thousand kg of milk per past lactation) and lactation (3–4 lactation). Unlike the control cows, animals experimental (ІІ) group for two months were fed by mineral supplements in the form of cobalt citrate in an amount of 19 mg Co/kg of dry matter of diet and research (ІІІ) – cobalt citrate in an amount of 34 mg Co/kg of dry matter of diet. Duration of cobalt citrate feeding of cows of research groups was 2 months. In all groups of cows the samples of venous blood were taken in preparation for feeding additives period and during 60 day of additives feeding period in order to determine the concentration of total protein, ceruloplasmin, sialic acids, hexoses bound to proteins and activity of amino transferases. The milk production has been controlled in days of sampling with the definition of daily milk yield per cow and taking an average sample for the determination of milk fat, protein, lactose, inorganic phosphorus and calcium. It has been established that the inclusion in the diet of cows of experimental (ІІ) group of mineral supplements contributed to an increase in animal blood total protein content by 11.9% (P < 0.05), inorganic phosphorus by 15.3% (P < 0.05) and hexoses bound protein by 8.8% (P < 0.05). Under these conditions milk content of inorganic phosphorus increased by 5.6% (P < 0.05) and average daily milk production increased by 4.5%. The use of mineral additives in third experimental group of animals within two months contributed to an increase in blood ceruloplasmin content by 5.1% (P < 0.05) and hexoses bound protein by 11.5% (P < 0.01). Mineral supplements promote 5.4% raise of average daily milk production and increase it to the lactose content by 0.10% (in absolute).

Milk production under grazing conditions is carried out in the intertropical region of hot climates due to its low production cost. The Tropical Milking criollo breed (LT) is characterized by its hardiness in this region, and its high milk quality and cheese yield. Grazing supplementation can increase milk production; however, it can also change its chemical composition. The effect of supplementation with commercial feed in LT cows was evaluated concerning the quantity and physicochemical traits of their milk by lactation. The treatments used were feeding based only on grazing para grass (Brachiaria mutica) and grazing plus 1 kg supplementation with 20 % protein commercial feed for every 5 kg of milk produced daily. The daily milk production per cow increased from 5.82 ± 0.18 to 7.10 ± 0.18 kg due to supplementation. Dry matter intake was similar in both treatments. The concentration of fat, protein, lactose, non-fat, and total solids did not suffer modifications (p > 0.05), but the daily production of each component per cow increased in animals supplemented due to the multiplicative effect of the amount of milk. The number of calvings affected milk production, fat, and ureic nitrogen in milk, and somatic cell count (p ≤ 0.05). It can be concluded that the supplementation used in this study was enough to increase milk production by 22 %, without modifying its chemical composition.

This paper shows the results of production and chemical compo­sition of cow’s milk on a farm MILKO-HF, Prilep, R. Macedonia with capacity of 100 cows of Holstein-Frisian breed divided into two groups (control and experimental). In control group I which was fed in a standard way of nutrition (ration used on the farm), average daily production of milk per cow ws 22.49 kg with the following chemical composition of milk: average daily content of milk fat is 3.75%, protein 3.57%, lactose 4.65%, nonfat dry matter 9.56% and total dry matter 13.31%. In experimental group II which were fed with the ration according to normatives, average daily production of milk per cow is 24.04 kg with the following chemical composition of milk: average daily content of milk fat is 3.99%, protein 3.57%, lactose 4.65%, non-fat dry matter 9.58% and total dry matter 13.57%. The obtained results show the increase in milk production for 1.55 kg-6.89% and better chemical composition of milk in the experimental group of cows. Thus, dry matter was increased from 13.31% to 13.57%-1.95%, milk fat content from 3.75% to 3.99%-6.4%, nonfat dry matter from 9.56% to 9.58%-0.21%, while the content of protein and lactose stayed on equal level. It was determined that the normed nutrition has influenced on production increase and better chemical composition of milk without unnecessary spent high level of nutrient i.e. nutrition of cows according to recommended normative.

ABSTRACT: The effect of insulin administration on the productive responses of Saanen goats during early lactation was investigated. Ten of 20 adult females were subjected to subcutaneous administration of intermediate-acting insulin (0.14UI/kg body weight) at 2, 9, and 14 days postpartum. Milk yield was measured twice daily for 13 weeks and milk samples were collected to measure protein and fat contents. Plasma levels of progesterone, insulin, non-esterifies fatty acids, glucose and other metabolites were measured. Results showed a significantly increased effect of insulin treatment on the content of milk fat and protein; moreover, milk production in the first and second postpartum weeks were higher than control group. The peak of lactation in the insulin group was achieved one week earlier in comparison to the control group. In addition, the milk production rate showed lower persistency (milk yield 13 week/milk yield at peak) in the same group. During the first four weeks of postpartum, treated animals showed greater weight loss and higher non-esterified fatty acid concentration, whereas no effect was observed on the concentration of progesterone and other metabolites. The above results indicated that repeated administration of insulin in dairy goats during early lactation increase yield and qualitative components of milk, but has substantial consequences on animal productive rate and metabolic response.

SUMMARYStatistical analyses were carried out on the data obtained under very strict conditions in metabolism stalls with 41 different rations fed to 127 adult non-pregnant dry cows, and with 14 other different rations fed to 35 adult non-pregnant lactating cows that had calved 2–6 months earlier and whose daily milk production ranged from 11 to 20 kg.The authors have calculated and studied the correlations between faecal and urinary losses of chloride, chloride excretion with the milk, digestible chloride and chloride balance and many other nutritive factors which were analysed for each of the 55 above mentioned experimental diets.The results show that the digestion and utilization of chloride is not influenced by the amount of ingested chloride at the time of the trial. The digestion is generally very high, negatively correlated with dry matter, energy, and pentosans intakes, and positively with nitrogen and potassium intakes. But the most important factor in the fate of dietary chloride seems to be the necessity for the cow to eliminate most of the time high amounts of potassium in the urines.

Repeat breeding is a reproductive disorder that harms dairy farmers because of the unachieved target to obtain one calf per year and decreased milk production. The repeat breeding syndrome can be caused by malnutrition. This study aimed to determine the effect of feeding silage, complete feed, and growth promoters in repeat breeder cows to restore the services per conception (S/C) and daily milk production. Thirty repeat breeder Holstein Friesian cows were divided randomly into three groups. The control group (P0) was fed 30-40 kg forage and 3-4 kg concentrate/head/day. Group P1 was given 8-10 kg silage or complete feed alternately every day; whereas P2 was given the same as for the P1 group, added with 10 ml growth promoter/head/day. Milk production and S/C were measured after six months of treatment. The results showed that the P1 and P2 groups returned S/C to normal (1.40 ± 0.52 and 1.30 ± 0.48), while the S/C of P0 group was 3.20 ± 0.63 (p <0.05). Daily milk production in the P1 and P2 groups (14.20 ± 1.40 and 14.60 ± 1.43 l/d) was also higher (p <0.05) than the control group (8.30 ± 1.06 l/d). It could be concluded that feeding silage and complete feeds alternately daily, with or without the addition of growth promoter, improved the S/C to the normal range and increased milk production.

The application of oxytocin induction to milk production in relation to the performance of kids in dairy goats had been carried out in the "PEGUMAS" dairy goat farmer group Gumelar District, Banyumas. This activity aimed to increase milk production and kid performance through the induction of the hormone oxytocin in dairy goats. The approach method was designed in two stages: the first stage carried out the socialization activities and demonstration of techniques for applying IPTEKS, and the second stage applied hormonal technology in the form of oxytocin hormone induction in dairy goats. The material used was dairy goat parity I aged 1.5 - 2 years allocated into 2 groups of 10 individuals each. Group I was dairy goat experiment not induced with the oxytocin hormone as the control. Group II was dairy goat experiment induced with the oxytocin hormone at a dose of 1 ml (10 IU) intramuscularly before milking. Milk production was measured morning and evening as daily milk production in milliliters (ml). Milk was given to the kid of each parent. The kid's performance was measured based on the daily weight gain of the kid during the study. Overall, the application of science and technology could be adopted by farmers, and oxytocin-induced dairy goat milk production (503.2 ml) was significantly higher (P<0.05) than control (305.4 ml) with an increase of 64.77%, with a positive level of correlation (r = 0.45) and contributed 19.83% to the kids daily body weight gain.

Investigation of some production traits in two production years (2005, 2006) was carried out on East-Friesian sheep. Considerably (P<0.01) higher milk production (346 lit.) in 2005, in comparison to 2006 (250 lit.) was registered. The duration of lactation is considerably (P<0.01) greater in 2006 (264 days), compared to 2005 (232 days). The content of milk fat in the milk from this breed is in average 5.01%, i.e. 5.64%, for the two years consequently. The production of milk fat is 17.34 kg in 2005 and 14.11 kg in 2006. The percentage of proteins in our research, in average is 4.68% in 2005, i.e. 4.85% in 2006, while the production is 16.19, i.e. 12.12 kg. The number of obtained lambs per sheep is not considerably higher (P<0.05) in 2005 (1.64 lambs) in comparison to 2006 (1.48 lambs). Almost all the examined factors (year, lactation, number of milk control) highly influence (P<0.001) the daily milk production, with the exception of the year, which influences with a considerable importance (P<0.05) the evening milk. In regard to the milk fat, statistically highly significant (P<0,001) influence was established only of the number of sequence and the month of the milk control, while all the rest fixed factors (year, lactation, number of lambs) didn?t influence significantly (P>0,05) this component of milk. Except of the fats, all the examined factors influenced statistically highly significantly (P<0,001) proteins in the milk, with an exception of the number of lambs, which did not influence considerably (P>0,05) this component.
