The aim of this study was to evaluate production and reproduction parameters after the birth of twins in holstein cattle (H = 100 %). Evaluation was made in terms of days open (the period between calving and conception; DO), milk production (kg of milk; % of fat, protein and lactose; kg of fat and protein; somatic cell count) and frequence of culling after the birth of twins. Milk production following the birth of twins was compared with milk production in controls matched on characteristics such as identical father, mother reaching the same breeding value of milk kg (± 10 %), evalued lactation occurring on the same farm, in the same year and period (±3 months). The goal was to pairs cows as cohorts with similar origins and production parameters under the same conditions and time. Days open after twinning in the multiple births were compared with days open in previous lactation and also with their cohorts. The data were analysed for 196 Holstein cows which gave birth to twins. The results showed a significantly (P ≤ 0.05) longer number of days open for the twin births. The prolongation was an average of 19 days. Days open through twin births was 132.62 days (sx = 62.22); in the previous lactation it was 113.54 days (sx = 63.14) and in cohorts 113.00 days (sx = 50.57). Milk production was similar in cows with twins and in cohorts (7907; 7871 kg). Average fat, protein and lactose percent in lactation was insignificantly lower in cows with twins (reduction: −0.08; −0.05; −0.02 %). Fat, protein and lactose percent was as follows in the group with twins compared to cohorts (3.72 vs. 3.80; 3.33 vs. 3.38; 4.94 vs. 4.96 %). From this arose an insignificantly lower production in kg of fat and protein (291.14 vs. 297.13; 261.49 vs. 264.74 kg). In the first three milk yield control after multiple births was found an insignificantly lower somatic cell count than in controls (149,7 thousand vs. 188.87 thousand). Frequence of culling after twin births (196 cows = 100%) were on health and reproductive grounds 78 cows (39.8 %) and for other reasons, 15 cows (7.65 %).

This study was carried out to investigate the effect of udder measurements group on somatic cell count (SCC) and daily milk production. Milk samples and udder measurements were collected monthly from 79 lactating Holstein cows on commercial dairy in the province of Niğde. In the study, front teat length (FTL), rear teat length (RTL), front teat diameter (FTD), rear teat diameter (RTD), distance between front teats (DBFT), distance between rear teats (DBRT), front udder height, (FTH), rear udder height (RUH), distance between front and rear teats (DBST) were obtained in before afternoon milking. Udder measurements were divided into 5 groups according to the measurements. The effect of DBFT, DBRT, FTH, RTD, FTD and DBRT groups on daily milk production were statistically significant, while FTH, RUH and DBRT were found non-significant. The effect of udder measurements groups on SCC was found not significant, except rear teat diameter (RTD). Average daily milk production and SCC were estimated as 28.25 kg/day and 274.90 cell/ml, respectively. In conclusion, it can be said that the distance between teats, teat’s diameter and front udder height of Holstein cattle is important factor for milk yield of Holstein dairy cattle. Also, SCC is effected by rear teat diameter.

The level of production and the physiochemical traits of rabbit milk affect the growth and the mortality of bunnies during lactation. The goal of the study was to analyze the effect of litter size and day of lactation on the quality traits of rabbit milk, milk production, and associative traits. The study was conducted on 32 Hycole does and their litters. The rabbit milk pH ranged from 6.61 to 7.46. The colostrum was characterized by the highest content of total solids (31.54 and 31.80 g kg−1) and fat content (15.73 and 15.9 g kg−1). The milk from the beginning of the lactation was characterized by the highest level of somatic cell count (SCC) (523.67 and 536.57 103 mL−1), which gradually decreased to reach the lowest level on days 17 and 21 of lactation. The daily milk production was greater for does nursing 10 kits per litter compared to those nursing eight kits per litter (p < 0.001). The peak of milk production occurred on day 17 postpartum. To conclude, the litter size has a clear effect on milk production as well as litter weight and litter weight gains. It is also important to note that the day of lactation affected the physiochemical traits of rabbit milk.
