“…Some researchers reported high persistency of Egyptian goat breeds (Baladi, Zaraibi and Damascus), with a slightly higher yield during the initial part of lactation (Laes-Fettback and Peters, 1995). Similarly in Damascus goats, Katanos et al (2005) recorded no significant differences between the average daily milk yield (1.26 ± 0.06) at weaning (7–8th week) and that at mid stage of lactation.…”

The objective of this study was to elucidate the impact of lactation stage on milk composition, hematological and biochemical parameters of dairy Baladi goats under Egyptian conditions. Forty-eight Baladi goats (32.8 ± 2.9 kg of BW) were enrolled in the current study. The lactation period has been divided into three stages; early (DIM less than 80 days), Mid (DIM 80–140 days), and Late (DIM over 140 days). Baladi goats had decreased daily-MY at a rate of 18.4% and 31.9% at mid and late stages of lactation, compared with early stage, respectively (p = 0.001). Furthermore, lactose% decreased significantly with progress of lactation (p = 0.017). Total solids%, however, decreased significantly at early stage of lactation in comparison with mid and late stages (p = 0.022). On the contrary, no significant differences were found in protein, fat and SNF percentages at different stages of lactation (p = 0.836, 0.625 and 0.281, respectively). Serum glucose and total protein were significantly reduced at late stage of lactation in comparison with early and mid stages (p = 0.001 and 0.001, respectively). On the contrary, no significant differences were found for erythrocytes count, hemoglobin, serum cholesterol, catalase and triiodothyronine at different stages of lactation. There were high and positive correlations between daily-MY and serum total protein (r = 0.87, P < 0.01) and triiodothyronine (r = 0.41, P < 0.01). However, negative estimates were reported between daily-MY and triglycerides (r = −0.55, P < 0.01) and cholesterol (r = −0.33, P < 0.05). Our results indicate that dairy Baladi goats produce milk with relatively stable protein, fat and solid not fat (SNF) contents at the different stages of lactation, encouraging the continuous utilization of their milk in processing. Also, dairy Baladi goats seem able to maintain the most vital biochemical parameters.

Udder morphology traits were measured and subjectively assessed by the use of linear scores in 266 ewes of Tsigai (T), Improved Walachian (IW) and Lacaune (LC) dairy breeds. Animals were recorded repeatedly within and between lactations, therefore 772 sets of measurements and linear scores were collected in total. Udder measurements included: udder length, udder width, rear udder depth, cistern depth, teat length, teat angle, sum of cistern cross-section areas scanned by the ultrasound technique from the side and from the bottom in a water bath. Linear scores were assessed for: udder depth, cistern depth, teat placement, teat length, udder attachment, udder cleft, and udder shape from the aspect of machine milking. Analysis of variance was conducted by the mixed procedure of SAS statistical package. The model included effects of experimental day, parity, days in milk, random effect of animal and residual error. Subsequently, correlations between random animal effects for udder measurements and linear scores were computed for individual examined breeds separately. Subjectively assessed linear scores for udder depth, cistern depth, teat position and teat size showed high correlations with actual measurements of the respective traits on udder in all examined breeds (r p = 0.65-0.80). Linear scores for cistern depth and teat position were highly correlated (r p = 0.84; 0.77 and 0.90 for T; IW and LC ewes), suggesting that they are nearly identical traits. Linear score for udder shape was significantly correlated with the linear score for udder attachment in all examined breeds (r p = 0.79; 0.80 and 0.78 for T; IW and LC). In T and IW assessments of the udder shape were also highly correlated with linear score for udder height (r p = 0.84 resp. r p = 0.79) while in LC this correlation was close to zero. In LC assessment of the udder shape was more dependent on teat position (r p = -0.37) and cistern depth (r p = -0.30).

“…In one study carried out on dairy goat farms with different type of breeds in Greece, Katanos et al (2005) have mentioned that traditional milking technique has a negative impact on the quality of milk and its products as well. The average milk yield per day was found as 1.99 ± 0.11 kg in Saanen breed and it was higher compared to other breeds such as Damascus, Saanen Â Local, Saanen Â Alphin and (Saanen Â Local) Â Saanen.…”

In order to determine the current status of milking characteristics, hygiene and health protection practices in Saanen goat farms in Turkey, data were obtained from 92 farms through surveys in Çanakkale province. The farms are grouped according to the number of animals as small-scale (25-75 heads), medium-scale (76-150 heads) and large-scale (151 and overheads). As a result of the data observed, it has been seen that the majority of the farms (63.04%) had primary education and only 8.69% had education at the university level. While 44 farms have a milking machine or milking system in their farms, the other 48 farms use the hand milking. The 72.8% of the farms stated that they did not receive any training on milking hygiene and milking machines. Breast diseases are among the most common health problems in the farms (61.9%), followed by, digestive system diseases (8.6%), bacterial diseases (5.4%), foot diseases (2.1%) and viral diseases (4.3%), respectively. The prevalence of mastitis which is the leading cause of breast disease differs statistically in terms of scale (p < .05). In this period, the scale of the farms increased and the use of machine milking became widespread in dairy goat farms. Considering that Saanen breed goats, which have high milk yield, are also sensitive to diseases and are delicate breeds, it is important for the farmers to be educated and informed about breeding, herd management, and milking hygiene practices in order to increase milk production and quality and to prevent economic losses. HIGHLIGHTSThe current status of milking hygiene and practices was evaluated. Mastitis was the most common disease (39.1%) observed in Saanen goat farms. To prevent economic losses due to diseases, farmers should be trained on hygiene and management practices. ARTICLE HISTORY
