Abstract: aiming to understanding the goat industry in the state of rio de janeiro, from 1998-2000, this study was carried out in 48 goat farms, 72.9% of which with an area of less than eight hectares. also, 62.5% of the farms had irregular topography, and 69% of them kept saanen breed in a confined system (93.7%). animals were housed between 16 to 24 hours/day in suspended wooden stalls, and 83.3% were dairy goats.

Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2005.411
Abstract: Good goat nutrition is fundamental to the success and sustainability of dairy goat farming in terms of economics, goat health, high quality products, and minimizing environmental impact.

Abstract: two dairy goat systems conducted according to the household model were evaluated in terms of income generation. an enterprise budget analysis was performed using data collected from august, 2004, to july, 2005. farms named a and b were smallholdings and raised saanem goats intensively. herd indexes, incomes, taxes, fuel, energy, concentrates, opportunity costs and interest in capital were computed. net present value and internal rate of return were estimated to appreciate the business appeal in terms of income generation. herd indexes were mostly affected by management decisions interfering on the amounts and time-trends related to milk production. seasonal variation was reduced at unit b due to heat induction, a decision not shared by farmer a. the daily body weight gain of doelings after weaning (89 and 76 g/d for a and b) was low if compared to current recommendations. average records of lactation (441 and 606 l/doe) and fertility (86.95% and 85.71%) were amongst the literature range. daily tasks related to unit b consumed 5 hours and 55 minutes for an average milk production of 40.9 l/d, whereas 8 hours and 16 minutes on average were daily spent at unit a in order to produce 32.2 l/d. unit b presented a total production cost (r$ 0.79548/l) lower than unit a (r$ 1.50239/l), but operated profitably. unit a presented a positive gross margin (r$ 0.284/l), but operated unprofitably. the income generated on b was equivalent to a monthly salary of r$ 732.96 (us$ 278.52), a competitive income compared to the brazilian minimum wage of r$ 300.00 (us$ 114.00) paid monthly. these results corroborate the hypothesis that the dairy goat husbandry fits adequately to the household production model and generates income competitively.

Agricultural Journal , 2013,
Abstract: A data issued from 16 years performances schedule of local goat, Alpine, Damascus, Murciana and crossed groups was used to study the genotypes productive behaviour under Tunisian oases conditions. The aim is to evaluate the possibilities of local goat productivity improvement by cross breeding in intensive mode and also, to choose the better improving breed and the cross level. About 1923 individual goat milking data was used to evaluate the dairy potentialities of local goat, imported breeds and crossed genotypes. A statistical analysis was applied on estimated dairy performances such as, daily milk average, total production by lactation and milking period. The cross breeding with imported breeds improves the dairy performances since the first generation. The crossing between these goats races appreciably improves the dairy performance of the local goat and this, as of the first generation. The dairy production with this generation is, about 248 kg for the Alpine one, of 181 kg for Damascus and 190 kg for Murciana, is only 137 kg by lactation for the local breed.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2010.429.435
Abstract: Agriculture especially animal product markets are vulnerable in the crises times. The 2006-2008 period has passed within different crises in entire world. Each crisis has an effect on agricultural sector. Extreme meteorological events due to climate change, food crises and finally Global Financial Crises in 2006-2008 affect the number of actors. In this study, it was studied that the outlook of the agricultural sector and dairy sub sector in Turkey in this period. Therefore, general structure of crises, economic and sectoral developments were given. And dairy sub sector expected to be mostly affected was examined as a case.

Agricultural Journal , 2013, DOI: 10.3923/aj.2012.414.415
Abstract: Agave plant is the main ingredient for tequila manufacturing mainly due to sugar content of the core which is cooked before juices extraction, the solid waste (pulp) obtained may be used in animal feeding. Nine lactating dairy goats were blocked by production level and used to assess three substitution rates (0, 25 or 50%, dry matter basis) of agave pulp instead forage in the diet. Animals were individually lodged and feed ad libitum, fresh tap water was offered daily. The trial was 21 days long and the last week was used for sample collection, measurements of intake, milk yield and milk quality. The goats were weighted at the beginning and at the end of the trial. Feed intake averaged 2.41 kg day-1 and was not affected by the level of pulp (p>0.05). Milk yield augmented 34% with the 50% of agave pulp in the feed (p<0.05) but percentage of nutrient was unaltered (p>0.05), however the nutrient daily production of protein and lactose was increased (p<0.05). Body weight and back fat were similar among treatments (p>0.05). Based on the finding, it could be concluded that the pulp can substitute corn stover in dairy goat without affecting animal health and performance.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.4585.4592
Abstract: Ghrelin, a gastric acylated peptide has been shown to express in gastrointestinal tract of many animals. However, little is known about its expression pattern in gastrointestinal tract of ruminants such as goat. In this study, researchers investigated the expression and distribution of ghrelin in the gastrointestinal tract of goat (Saanen dairy goat) including esophagus, rumen, reticulum, omasum, abomasus, duodenum, jejunum, ileum, appendix, colon and rectum by PCR, Immunohistochemistry (IHC) and Western blot. The PCR detection showed that ghrelin mRNA existed in all the above tissues and was significantly higher in the abomasus than in other tissues detected (p<0.05). Immunohistochemistry assay showed that ghrelin-positive cells were observed in the mucosal layer of all segments examined. The ghrelin-positive cells were most numerous in the abomasus, less abundant in the duodenum, occasional in jejunum, ileum, appendix, colon and rectum and rare in esophagus, rumen, reticulum, omasum and abomasus. Western blot analysis confirmed the ghrelin protein expression pattern in the gastrointestinal tract of the goat. These results demonstrate that ghrelin is expressed in the gastrointestinal tract of Saanen dairy goat, especially in the abomasus.

Ciência Rural , 2008, DOI: 10.1590/S0103-84782008000200044
Abstract: poisoning of a goat by leucaena leucocephalai (leg. mimosoideae) in the state of rio de janeiro, brazil, is described. fresh leaves of the plant were ingested as the animal's main meal for at least 4 months before it developed total alopecia. at necropsy the thyroid was moderately enlarged. histological examination revealed a decrease in the number of hair follicles (empty or in telogenic phase), vacuolation of keratinocytes of the epidermis and hair follicles, and superficial and follicular hyperkeratosis. myxedema was found between skeletal and cardiac muscles fibers, in the kidneys, and in the submucosa/muscular layer of the digestive tract. the thyroid follicles were enlarged and filled with copious amounts of colloid (colloidal goiter). although l. leucocephala is common in several tropical regions, natural poisoning by this plant in goats seems to be rare. it is the first report about spontaneous poisoning in goats by l. leucocephala in brazil.

Abstract: The productive characteristics of Chinese Henan dairy goat and its development in central China are presented. Adult males being 82.86 cm and adult females 65.27 cm high at withers, weighing 69.9 and 39.96 kg, respectively. This breed has a high reproductive performance. Male and female kids reached puberty at a mean age of 120 and 150 days, respectively. The number of kids at one time varies from single to septuplet with the kidding rate is given as 2.02. Goat fed only on grass in first parity period, produced 619.19 kg milk in 305 days of lactation and 668.4 kg in second parity, 698.73 kg in third parity. The total solids, protein, ash content were rich in goat milk. On slaughter performance when kids are 10 months old, the live eight is 37.25 and 33.15 kg, carcass weight is 19.00 kg and 16.34, the slaughter rate are 54.09 and 53.00%, carcass dressing rate are 43.62 and 42.11%, respectively in male and female kids. The dairy goat s fate in Henan province will be great attention.
