Twenty-two elements have been identified as essential to the growth and health of animals. They include 7 macroelements and 15 microelements, which play four key functions in the body: structural, physiological, catalytic and regulatory. Mineral deficiencies can result from low quality feed, impaired absorption or assimilation in the body or increased demand for minerals during intensive growth, pregnancy and lactation. Mineral-deficient feed and diets with an unbalanced mineral content impair the growth and development of young animals, decrease appetite, lower nutrient absorption, decrease immunity and increase susceptibility to contagious diseases. This paper discusses the consequences of low levels of macronutrients and micronutrients that are required for the optimal growth of calves, lambs and kids, including calcium, phosphorus, magnesium, selenium, cobalt, iron, zinc, copper, sodium, potassium and chloride.
The efficiency of tranfer of maternal immunity and its infuence on the kids' health was observed in a herd in which kids (n=20) had whole contact with the dam (n=13). The factors associated with dam, kid and human, which influence the efficiency of passive transfer were observed. It was estimated that the single-born kids reached higher serum y-globulin level (mean 23.14 g/dm3) than twin kids (mean 18.2 g/ dm3) (p < 0.05). The y-globulin level was the highest in single-born kids at 48 h, and in twin kids in 24 h of life. The IgG class antibodies to herd-homologous strains of Pasteurella multocida and Escherichia coli were estimated using ELISA in sera, colostrum and milk whey samples of dams and sera of kids. It was found that maternal antibodies specific to these two facultative pathogens decreased in kids sera rapidly and the self humoral immune response occurred within the period of observation. Two kids delivered by goats with lowest hierarchic position in the herd showed failure of passive transfer, and died at the 10th and 12th weeks of life due to chronic infections induced by both above mentioned bacterial strains.
The purpose of the paper was to assess the effect of administering a feed containing flax seeds on the fatty acid composition and cholesterol content in the meat of goat kids and ram lambs. The basic physicochemical properties of the meat were also determined. The analyses showed a significantly higher (p≤0.05) protein content in the goat kids (20.20 g) as compared with the ram lambs (19.50 g). The other chemical composition parameters were similar. The pH1 and pH2 results confirmed correct glycolytic metabolism. The obtained values were 6.39 and 6.27 for the goat kids and ram lambs, respectively. The pH2 value was 5.70 for both groups of animals. The analysed goat kid meat was characterised by better UFA:SFA and PUFA:MUFA ratios. The addition of flax seeds significantly differentiated the CLA (p≤0.01) and cholesterol (p≤0.05) content.
The experiment was conducted to determine the effect of adequate zinc level supplementation (inorganic versus organic form) on the innate immune response of kids. The count of white blood cells, leukocyte differential count, phagocytic activity, and phagocytic index (as markers of the immune functions) were determined. Phagocyticic activity was not significantly higher in the inorganic-zinc-treated group in comparison to the control (64.7±8.91 vs 61.2 ± 9.15 %). The production of reactive oxygen species (ROS) by goat's blood neutrophils was detected by luminol-enhanced chemiluminescence (CL). CL was performed to determine integral CL, peak CL, and peak-time after addition of calcium ionophore A23187 (Cal-I), opsonised zymosan (OZP), and phorbol- 12-myristate-13-acetate (PMA). A significant ROS increase reflected in peak CL (P≤0.05) was found in the lactate-Zn-treated group when Ca-I was used as activator. In the same group there was a significant integral CL increase (P≤0.05) when we used Ca-I as activator. Others parameters showed no significant changes.
Contagious ecthyma (CE) is a highly contagious viral skin disease that is typically self-limited. Treatment options include topical antiseptics, such as KMNO₄, local antibiotics and systemic antibiotics to prevent secondary skin infections. The aim of this study was to compare the effectiveness of the lincomycin/spectinomycin combination and dexpanthenol (Dxp) in goat kids with CE. The study was conducted at a Saanen dairy goat farm in Bursa, Turkey. The owner of the goat herd inquired at the veterinary hospital about the appearance of granulomatous lesions on the muzzles of goat kids. In this study, 24 goat kids (1-month-olds) were used. All animals were subjected to the same conditions. Blood and papule samples were taken from the animals’ lips, muzzle and buccal mucosa for virological analysis. Swab samples were taken from the lesions for culture and antibiogram. The animals were divided into three groups. Lesions were clinically scored at days 1, 7 and 15 according to a modified previously used scoring system. Goat kids were equally grouped on the basis of lesions on the buccal mucosa, lips and muzzle. The animals in group A received 15 mg/kg lincomycin/ spectinomycin combination (Lypectin®, Vilsan) intramuscularly for 3 consecutive days, group B received 20 mg/kg Dxp (Bepanthen® amp, Bayer, Germany) intramuscularly for 3 consecutive days, and group C received 0.9% NaCl (2 ml), the control treatment. Clinical recoveries were almost equal in all groups, but by day 14, group A showed better recovery than group B and group C. Both study groups also showed better results than the control group for all days. In conclusion, we believe that the lincomycin/spectinomycin combination or dexpanthenol can be useful in the supplementary treatment of CE in goat kids.
The aim of the study was to estimate the content of Pb, Cd, Zn, Mn, Cu, Fe, Ca in meat and liver of male kids and ram lambs fed mixtures containing 10% of flax seeds. Castrated male kids (n = 7) of White Upgraded breed and castrated ram lambs (n = 7) of Polish Lowland sheep fattened up to about 35 kg of body weight were used as experimental material. The animals were fed mixture CJ ad libitum, supplemented with 10% of flax seeds and meadow hay as a structural supplement. Contents of the chemical elements were analysed in samples of longissimus dorsi muscle. The content of Cd (0.01 mg kg–1) in male kid meat was lower than in ram lamb meat (p ≤ 0.05). Similarly, Pb content was lower (p ≤ 0.05) in male kids (0.04±0.003 mg kg–1) than in ram lambs (0.07±0.002 mg kg–1). Slightly lower content of Pb (by 0.01 mg kg–1) and Cd (by 0.01 mg kg–1) in male kid liver was determined, and the differences were statistically insignificant. Significantly larger (p ≤ 0.01) Cu content (1.14±0.07 mg kg–1) in muscular tissue of ram lambs was also stated. Male kid meat, however, was richer in Mn, Fe, Zn and Ca, with the differences tested at p ≤ 0.05 and p ≤ 0.01. The liver was an organ which accumulated not only Pb and Cd but also Cu, Mn and Zn both in ram lambs and male kids. Especially high level of Cu and Mn in liver was found, which could be the result of a high content of the chemical elements in mixtures. Moreover, significantly larger content of Ca (15.24±1.68 mg kg–1) in ram lamb liver compared to male kid liver was stated. On the other hand, muscular tissue of male kids contained more Ca (21.94±1.74 mg kg–1) than that of ram lambs. The content of chemical elements (especially heavy metals) in muscular tissue and liver was lower than the norms established by the Minister for Health and the European Committee, which prove that the tested food products were fully safe for consumption.
In the experiment, goat kids of white improved breed and ram lambs of the Polish Lowland sheep fattened up to 150 days, were studied. After weaning, the animals at the age of about 70 days old were fattened "ad libitum" with all-mash pelleted feed CJ the additive containing 6.1 MJ EN and 182 g of crude protein, and meadow hay additionally. The main aim our study was determined the differences in fatty acids compositions of intramuscular fat of goat kid and ram lambs, fed with the same feed and kept in the same conditions. Results of the study showed that lambs were significantly heavier (36.64 kg) and had got a higher weight of warm carcass (16.67 kg). The kid meat showed significantly higher content of protein (20.21%) and mineral compounds (1.13%) and lower fat content (2.28%). Lamb meat contained more dry matter as well as crude fat and less protein and mineral elements than goat meat. Muscles of goat kid characterized 3.55 p.j. (percentage units) lesser contents of palmitic acid (C16:0 ) and 4.33 p.j. of stearinic acid (C18:0 ). Significance of differences was confirmed statistically. Among determined monosaturated acids dominated oleinic acid (C18:1 ): in goat kid tissue 54.1% and ram lambs tissue 47.5%. From among acids polyunsaturated significant differences stepped out among fatty acids; C18:2 , C18:3 , C20:4. In the researcher's study, this indicator was slightly below this optimum ratio and ranged from 1.60 for goats and 1.29 for rams. In the experiment, favorable proportion of UFA:SFA characterized of goat kids (1.69) incomparision with ram lambs (1.22). The differences among studied animals were significant statistically.
Slaughter indicators of synthetic Whiteheaded Mutton line ram lambs (RLs) were compared to those of 75% Boer and 25% White Improved crossbred male kids (MKs), both groups fattened to the age of 100 days. Considered was body weight (BW) at slaughter, individual organs and tissues content of BW, carcass quality indicators and carcass tissue composition. At the age of 100 days RLs reached higher BW and dressing percentage than MKs, and share of valuable cuts in their carcasses appeared higher. Carcasses of RLs showed better conformation (a wider thorax, wider rump, bigger leg circumference, higher leg rounding index), but their subcutaneous fat layer was thicker than that of MKs. Meat per cent of RLs carcasses was found similar to that of MKs carcasses, but the former contained more fat and less bone than carcasses of MKs.
